In this paper, we propose an algorithm to estimate sleep quality based on a heart rate variability using chaos analysis. Polysomnography(PSG) is a conventional and reliable system to diagnose sleep disorder and to evaluate its severity and therapeatic effect, by estimating sleep quality based on multiple channels. However, a recording process requires a lot of time and a controlled environment for measurement and then an analyzing process of PSG data is hard work because the huge sensed data should be manually evaluated. On the other hand, it is focused that some people make a mistake or cause an accident due to lost of regular sleep and of homeostasis these days. Therefore a simple home system for checking own sleep is required and then the estimation algorithm for the system should be developed. Therefore we propose an algorithm to estimate sleep quality based only on a heart rate variability which can be measured by a simple sensor such as a pressure sensor and an infrared sensor in an uncontrolled environment, by experimentally finding the relationship between chaos indices and sleep quality. The system including the estimation algorithm can inform patterns and quality of own daily sleep to a user, and then the user can previously arranges his life schedule, pays more attention based on sleep results and consult with a doctor.

Parallel beam structure has many significant features, as follows. (i) The tip moves in parallel at the end. (ii)This structure converts the small displacement into the large strain. (iii) Each unit doesn't interfere to the other units by piling up this structures. We used this structure for piezoelectric vibrating gyroscope (angular rate sensor). In this paper, we analyzed features of the parallel beam structure by Finite Element Method, and showed that the resonance frequency of the drive unit and the sensor unit can be easily adjusted by changing the mass at the tip. From this result, this structure suits for the gyroscope. Experimental results are shown.

電子ビーム誘発された堆積(EBID)はカーボンナノチューブ(CNT)エミッターを通して実現された。ナノマニピュレーションによってナノチューブエミッターと基板の間のギャップが377nmに調整され, 120Vのバイアスをかけて, 2μAの放出電流が得られることを示した。同じ真空室の電界放出走査電子顕微鏡(FESEM)の熱電子銃による従来のEBIDと比較すると, ナノチューブエミッターのバイアスと放出電流は, それぞれFESEMの熱電子銃のわずか0.8%および1.9%であるが, 堆積率はそれの12.2%に達したことが分かった。そして, 最後にパラレルEBIDは提案された。

Development of fabrication technology made it feasible to fabricate micro order structures. Those technologies include machining, MEMS (Micro Electro Mechanical System) and laser fabrication. In micro-world, assembly becomes especially a crucial problem. We have developed an easy and fast assembly process of microparts called STAMP (Stacked Microassembly Process). In this process, three-dimensional structural object is fabricated by stacking up two-dimensional layers and micro-structures are cut apart after all the assembly is completed. Here, as an example, we have fabricated a model of stag beetle. Two-dimensional layer parts are fabricated by SU-8 photolithography and electroplating. Stacked parts are bolted together using micro-rivets.
