We develop termite prevention-of-the-breeding and extermination robots system. This robot system is applied technology of rescue robot system. The most important feature of this robot system is in collaboration with a worker to protect house from termites. Therefore, these robots are design according as safety guideline for service robots. The name of the robots system is named "mirubo". This research shows the method of evaluations for the mirubo III. The evaluations include main five examinations as mobility exam, velocity exam, illumination exam, injection exam and step-over-performance exam.

Matsushiro earthquake swarm is a most well known and well studied earthquake swarm in the history of seismology. From viewpoints of geophysics, geology and geochemistry, various observations, field surveys and analyses had been made to reveal characteristics of the swarm. On the basis of these studies, several models had been proposed to explain why and how the swarm originated and developed. However, majority of studies had focused on the activity around the climatic stage of the swarm in 1966 and so far, studies on the initial stage of the swarm in mid 1965 had remained few due to lack of sufficient observation data. The exact area where the swarm was born had not been known and the swarm was vaguely believed to originate from the area around Mt. Minakami in former Matsushiro town (now belongs to Nagano city). Considering that the manner of initial development of swarm activity represents an important characteristic of the swarm earthquake, we tried to get more clear view about initial stage of the swarm activity in this study. We re-investigated seismograms obtained by routine observation and studied seismograms of temporal stations for the first time which had not been processed yet. By scanning analogue seismograms, we made a complete data set of S-P times with high precision for each station. Although the data set of S-P times from two stations are not sufficient for conventional hypocenter location, we were able to narrow down a possible source area of the swarm activity under the reasonable assumptions. By considering direction of initial motion of P waves and assuming local velocity model of the upper crust in the region and plausible focal depth of 4.5km of the swarm earthquake, we found that the area of swarm in the very beginning in August, 1965 is located about 4km north-east of the Matsushiro earthquake fault (MEF) in former Wakaho town near its border with former Matsushiro town. Size of the initial swarm area was 3-4km in diameter. While swarm activity in the initial region was gradually decaying in September new swarm activity appeared separately from the initial swarm area around southern and south-west part of the MEF. Activity in the new swarm area had been increasing and it was developed to more intense swarm after October, 1965 when establishment of temporal seismic station network of the Earthquake Research Institute, University of Tokyo enabled detailed hypocenter location. The new swarm area coincides with the area where large amount of ground water moved upward and was released on the ground surface in the climatic stage of the swarm. It was well known that source area of the swarm was split and expanded toward north-east and south-west after March, 1967 in its climatic stage. Present study on the initial development of swarm area suggested that characteristics of the Matsushiro earthquake swarm such as splitting and expansion of its source area toward northeast and southwest were inherent in their early stage of the activity in August and September, 1965.

An analytical method for the determination of aromatic compounds exhalated from hand skin has been proposed. The sampling of exhalated aromatic compounds was performed as follows: after the intake of aromatic compounds included in chewing gum or a capsule, exhalated skin gas was collected from a hand. The hand was covered with a sampling bag of poly vinyl fluoride (PVF) for 30 min. Then, the inner space of the sampling bag was sprayed with a 25% of ethanol aqueous solution. After removing the hand from the bag, the trapped solution containing skin gas was collected. The aromatic compounds in the trapped solution were extracted to the solid phase as Twister® (stir bar coated with poly dimethyl siloxane, Gerstel). Extracts were determined by gas-chromatograph mass spectrometry using a thermo desorption system and a selective ion mode. Linalool, citronellol and geraniol, which are the main components of rose essential oil, were detected from the skin of a hand after an oral intake of rose oil. The exhalated absolute amount of linalool, citronellol and geraniol increased in 30 to 60 min, and then decreased after intake. The recoveries of linalool, citronellol and geraniol were 53.5%, 66.7% and 55.1%, respectively. The correlation coefficient of the standard curves for linalool, citronellol and geraniol were 0.9977, 0.9994 and 0.9987, respectively. Each compound exahalated from the skin of a human body during 6 hours after intake was estimated to be, according to the amount of intake, 0.39%, 0.09% and 0.25%, respectively, for one subject. The absolute amount of geraniol exhalated from a hand increased significantly after oral intake for 8 subjects (P<0.025). This is the first report to present hard proof that an aromatic compound was exhalated from human skin after its intake as food.
