In this paper, we investigate a new type of soft rubber actuator to realize a human friendly support device. Since the structure of the actuator is a soft mechanism that a sponge rubber is covered with silicone rubber, the actuator can realize a flexible motion to a human body. Further, the actuator can estimate external forces by making use of the equation with respect to the relation between inner pressure and external force. Therefore, the actuator can be used as a force sensor. In this study, we clear basic characteristics of the proposed actuator.

This paper answers how multiple satellites are seen from the ground. This question is inspired by space-advertising, a public exhibition in the night sky using a dot matrix of satellites that are bright enough to be seen by the naked eye. Thus, it is important for space advertisement that the specific dot matrix is seen. Moreover, the stability of the dot matrix during a visible span is very valuable. To stabilize the dot matrix, this study formulates an apparent position of a dot from a representative dot seen from the ground. The formulation, linear functions of a set of relative orbital elements, reveals the appearance of the dot matrix. The proposed relative variable in the formulation drives the instability of the dot matrix, thereby revealing an initial stable configuration of deputies from a chief. The arbitrary dot matrix designed using the configuration is stable even at low elevations without orbital control during the visible span.

本文开发了半导体融体的热扩散率的测量装置。通过引入石英玻璃试样容器将激光闪光法扩展到适合于融体试样。首先在实验及理论上研究了石英玻璃层对试样的热辐射及温度相应的影响,结果发现在室温以上温度范围,石英玻璃层的存在只减小红外辐射探测器的信号幅度但不改变时阃变化历程。由闪光法的原理,包含石英玻璃层的复合试样则可以作为单层试样处理。根据这一原理,我们首次对三元红外半导体融体In1-xGaxSb在不同组分时,温度范围800K至1200 K的热扩散率进行了测量。

ZnSe is a sereiconductor with a wide direct energy gap（2.7 eV）at room temperature and is suitable for blue light emitting diodes, lasers and other opto electronic devices. GaAs has been mainly used as a substrate of ZnSe. However. there exists a 0.27％lattice ismatch between them. This mismateh causes the generation of many dislocations and defects, and as a result the quality of ZnSe layers becomes poor. InxGa1-xAs can be adjusted its lattice con

用提拉法从熔体中拉制了InSb单晶。在长晶过程中,通过碳坩埚将超声振动导入熔体。拉出之晶体中心的小晶面区转移到了晶体的四周,尺寸也同时缩小了,这是因为超声振动搅动了熔体,并提高了它的温度。此外,还讲述了小晶面区和无小晶面区二者之间扩散电阻值的差别。这些结果表明:导入超声振动改善了晶体内部杂质浓度分布的不均匀。
