摘要： A flight machinery with high stability in the air having a pendulum structure and an active posture control principle which can be designed for universal purposes at a low cost is provided.The flight machinery includes a structure in which a main body and a lightweight wing having an unvalued weight compared with the main body are connected by use of a power joint on a line joining the center of a lift force and the center of gravity of the wing in the manner that the main body is positioned under the wing. Accordingly, it is possible to exhibit a function of the flight machinery by adjusting the power joint connecting the upper part and the lower part or the wing to the main body even if the wing and the main body have different characteristics. Additionally, it is possible to stabilize a posture by positioning the total center of gravity at the main body at the lower part. At the same time, it is possible to stabilize the posture just by controlling the position of the servomotor of the power joint. The flight machinery is inexpensive because the structure of the flight machinery is simple, and can be used conveniently and economically in industry because a design/development cost is low.

摘要： The exhaust temperature of the jet engine is set up to 750° C. so that a fiber group sound absorber member such as glass fibers having a high sound-proofing performance can be used by cooling it with bypass air. In order to prevent the fibers from being scattered by a jet flow, a boundary is covered with a mesh metal to form a boundary layer with the bypass air, so that the fiber group sound absorber member can be protected against the jet flow of a high temperature and a high speed and so that the sound-proofing effect of the excellent fiber group sound absorber member can be kept. Moreover, the sound absorber member is prepared by combining sound absorber members of different frequency characteristics, thereby to realize a remarkably high sound-proofing performance exceeding 200 dB.

摘要： A substrate such as a sapphire substrate or the like is set to a molecular beam epitaxy (MBE) apparatus. Next, the temperature of the substrate is elevated to the temperature which is lower than the temperature at which a predetermined ZnO based oxide semiconductor layer (i.e. function layer) is grown (S1). Then, raw materials containing oxygen radical is irradiated to the substrate to grow a buffer layer made of ZnO based oxide semiconductor (S2). Subsequently, the irradiation of oxygen radical is stopped so as to eliminate the influence of oxygen onto the buffer layer (S3). Then, the temperature of the substrate is elevated to the temperature at which the predetermined ZnO based oxide semiconductor layer is grown (S4). After that, raw materials containing oxygen radical is irradiated so as to sequentially grow a ZnO based oxide semiconductor layer as a function layer (S5). As a result, a ZnO based oxide semiconductor layer with low concentration of residual carrier can be grown, and a semiconductor light emitting device such as light emitting diode and laser diode with high light emitting characteristics can be obtained.
