Reduction of particulate matter (PM) in exhaust gas from automobile engines is in high demand. Fuel stuck on the engine wall causes incomplete combustion, and generates a large amount of PM. To prevent this, shape of fuel injection spray must be controlled with precision. We focused on the valve offset of the injector as a factor influencing the spray shape. Computational analysis was conducted to investigate the effects of the valve offset on inner nozzle flow and spray shape (spray direction and liquid penetration). Simulated spray behavior image, footprint, and liquid penetration agreed well with experimental results. From the inner nozzle flow simulation results with the valve offset, it was found that fuel tends to flow in the direction of the valve offset near a sac in the nozzle to provide the fuel to the holes. This flow was caused by the smaller flow path fomed in the valve offset direction. From the spray simulation results, shifts in the spray direction of the plumes were caused by the flows near the sac. Some plumes were injected in the direction opposite to the valve offset. The holes with larger drill angle located in the valve offset direction, and larger valve offset caused larger changes of spray directions. Furthermore, liquid penetration was investigated. We showed that the flow separation in the holes caused by the valve offset affects the velocity distribution at the hole outlet and results in changes of the penetration length when the drill angle is small. It was found that the valve offset causes the change in the inner nozzle flow, and results in the change of the spray shape. We concluded that the correlation of nozzle geometry and valve offset is important for controlling the spray shape.

On 6 types of Ni-Ti spreader (Roeko NiTi # 15; Roeko NiTi # 25; Roeko NiTi # 35; Roeko NiTi D11T; Brasseler Naviflex NT D11T; Brasseler Naviflex NT 4SP), dimensions were measured under digital microscope, and a load application test was performed in the axial direction of the spreader. The results were as follows: 1. In Roeko NiTi # 15, D<sub>3</sub> was 0.38 mm, D<sub>16</sub> was 0.61 mm, taper was 0.018, and tip angle was 28.9°. Similarly, the above values were 0.32 mm, 0.68 mm, 0.027, and 28.0° respectively in Roeko NiTi # 25. The values were 0.50 mm, 0.70 mm, 0.016, and 32.5° respectively in Roeko NiTi # 35, and the values were 0.37 mm, 0.88 mm, 0.039, and 10.6° respectively in Roeko NiTi D11T. The values were 0.27 mm, 0.77 mm, 0.038, and 29.9° respectively in Brasseler Naviflex NT D11T, and 0.30 mm, 1.06 mm, 0.059, and 35.9° respectively in Brasseler Naviflex NT 4SP. 2. When a load was applied in the axial direction of the spreader, the load was 0.56 kgf in case the portion of 16 mm in length from the tip in Roeko NiTi # 15 was bent at a stroke. When the portion of 5 mm in length from the tip was fixed and the portion of 11 mm in length from the tip was bent at a stroke, the load was 4.32 kgf. The above values were 1.13 kgf and 7.52 kgf respectively in Roeko NiTi # 25, 1.24 kgf and 8.58 kgf in Roeko NiTi # 35, 0.82 kgf and 10.28 kgf in Roeko NiTi D11T, 0.63 kgf and 7.27 kgf in Brasseler Naviflex NT D11t, and 1.02 kgf and 17.61 kgf in Brasseler Naviflex NT 4SP. 3. The Ni-Ti spreader has super-elasticity and is flexible. Thus, it is difficult to apply pressure on it in the axial direction, during lateral condensation. However, this study revealed that sudden bending may be avoided if at least the tip portion of 5 mm in length from the tip is inserted into the root canal.

触刺激に対するζポイント, ζ_tが網地に遭遇した魚の前進行動の継続に与える影響を調べるため, 失明させたコイ, ニジマス, ティラピア, ブルーギルを用いた水槽実験を行った。供試種では, 魚体の長さ方向での接触位置により前進後退行動が入れ替わり, ζ_tポイントの存在を確認できた。ζ_tポイントの位置は種固有で種間で異なる。網地に遭遇した魚の前進継続率は, 目合い, 縮結によって異なり, ζ_tポイントに基づく前進後退行動の分岐モデルに基づいて計算した前進継続確率でよく説明できた。刺網の漁獲過程で網地に遭遇した魚が網目に進入する確率は, ζ_tポイントの位置, 魚体の大きさと形状, 目合いと縮結に影響されると結論した。Two series of glass-tank experiments with blinded fish were conducted to investigate the existence of a ζ-point (a body section over which external stimulation alters forward and back ward motions of fish) against tactile stimulation and its effect in determining the direction of swimming upon contact with a net webbing. Cyprinus carpio, Salmo mykiss, Tilapia mossambica and Lepomis macrochirus were tested. Longitudinally random positions over the bodies of these fish were stimulated using thin sticks and they moved either forward or backward according to the location of the stimulated positions. Cyprinus carpio which encountered net webbing expanded in a tank proceeded into a mesh at different ratios under the conditions of three mesh sizes and three hang-in ratios. Geometrical analysis of contact of a netting twine and a fish body section indicated that the probability of proceeding into an encountered mesh increases with mesh size and is modally maximised at a certain hang-in ratio. It was concluded that, (1) a tactile ζ-point, ζ_t exists at a body section which is unique to each species, and (2) the probability for fish to proceed into a mesh of gillnet is affected by the position of ζ_t, body form and size, mesh size and hang-in ratio.

&nbsp;More than 75,000 emergency houses, called the standard prefabricated house, were built in Okinawa after the war in approximately four years, beginning in 1946, which made a great contribution to reconstruction. The standard prefabricated house was designed by a local architect named Hisao Nakaza (1904-1962) at the U.S. naval military government Okinawa public works department on Nov. 30, 1945.<br>&nbsp;The purpose of this study is to clarify the details of the situation about the process, the design and the supply system of the standard prefabricated house, and to also clarify the actual factor of the massive and quick supply. This paper consists of five chapters.<br>&nbsp;Chapter 1 describes the background based on the career and articles of Nakaza and why he began to design the standard house. According to his career, he had experience with evacuation house construction in wartime. After the experience was evaluated, Nakaza designed the standard house at the U. S. naval military government Okinawa public works department.<br>&nbsp;Chapter 2 considers the standard house plan situation of the U.S. naval government from directions. The naval government gave orders that let local people resettle from camps to their original places of residence on October 23, 1945. Therefore, the government had to supply houses. The direction of October 31, 1945 shows the design guide of the houses. It is thought that the scale and materials of the standard prefabricated house were decided based on this.<br>&nbsp;Chapter 3 analyzes the design drawing. The standard prefabricated house responded to the situation of a lack of engineers in that the frames of the walls and roof trusses were designed as prefabs which were produced at a factory. Furthermore, the design can respond to the lack of material flexibly, and the choice of finishing materials depending on the local situation is possible.<br>&nbsp;Chapter 4 investigates Nakaza's article and the Okinawa public works department relations documents, and understands the supply system. For approximately four months, from January to May in 1946, the constructions were instructed by three people, including Nakaza. From the period of May, 1946 to the end of 1949, constructions were carried out by an organized system by the public works department of Okinawa civil administration. The department was able to settle the U.S. government budget directly. Architectural division managed the material yards and carried out construction by construction units. In addition, motor pools of the land transport division took transports.<br>&nbsp;Chapter 5 analyzes the monthly construction number on the activity reports of the U.S. military government and assumes the construction end time. Construction was carried out most actively during the periods from the beginning of 1946 to mid 1947. The first action system was good; more than 4,000 houses a month in December, 1946 and January, 1947 were built. There are construction reports until October, 1949, which show that the houses were built until about the end of 1949. A total of about 76,815 houses were supplied within four years, from January, 1946 to October, 1949.<br>&nbsp;As above, the standard prefabricated house was designed by architect Hisao Nakaza, and supervised by the U.S. military government, and managed by local government, and constructed by mutual support among residents.<br>&nbsp;The main reasons to be able to serve a large quantity and quick supply are as follows. (1) The houses were a prefabricated type which the residents could easily build. (2) The design could respond to the lack of material flexibly, and the choice of finishing materials depending on the local situation was possible. (3) The compact organization system could perform the stocking, manufacturing, sending, and budgeting execution of the construction.

小倉 郵政改革で小泉さんは「小泉内閣が潰れるか、自民党が潰れるか」と言ったのは認識が明らかに違っていました。「小泉内閣は潰れても構わないから、郵政省を潰す」と言うべきでした。改革の目的は、郵政省という官僚組織をなくすこと。その点を明確にしないといけなかった。 青木 最近の外務省の不祥事を見ても、役人たちが好き放題をやっている。
