Title: Air liquefying cycle engine
Inventor: HIRAKOSO HIROYUKI
IPC: B64G1/40
Filed: 1990-07-30
Abstract: PURPOSE:To increase intake air quantity and improve performance by providing an air passage for compressing the residual air in an air liquefying chamber by an air compressor and sending it to a combustion chamber in a one in which the air is liquefied by use of a cold heat source, force-fed to the combustion chamber, and combusted with a propellant as the cold heat source. CONSTITUTION:The air is sucked into an air liquefying chamber 1 from an air intake hole 1a and passed through an air precooler 1 to reduce the temperature, and the liquefying latent heat is taken in an air liquefier 3 to liquefy a part of the air. The liquefied air is stored in a liquefied air tank 4 and guided to a gas-liquid mixer 7 by boosting a liquefying air pump 5. The gaseous air remaining in the air liquefying chamber 1 is boosted by an air compressor 6, passed through the gas-liquid mixer 7, mixed with the liquefied air, and injected into a combustion chamber 8. Liquid hydrogen which is a fuel is supplied from a tank through a liquid hydrogen pump 9, passed through the air liquefier 3 and the air precooler 2, and injected into the combustion chamber 8, in which it is mixed with the air and combusted to obtain a thrust. A part of the hydrogen getting out of the air precooler 2 is branched and supplied to a turbine 10 for driving the air compressor 6.

IPC: F01D5/26
Filed: 1994-08-24
Abstract: PURPOSE: To realize the diaphragm of a steam turbine for setting the number of nozzle wake vibrations different from the number of intrinsic vibrations of a moving blade and reducing a nozzle wave exciting force applied to the moving blade of having short moving blades of the number of intrinsic vibrations of a particularly high frequency for generating no resonance between the moving blade and the nozzle wake. CONSTITUTION: Nozzles 4, 5 and 6 disposed in the circumferential direction of a diaphragm are placed in a plurality of combinations of different pitches A, B, and C and attached to the diaphragm and thereby a nozzle wake which is generated due to a part of a nozzle trailing edge having a slot steam flow, is so formed as including mixture of different frequencies caused by difference in pitches so that a nozzle wake exciting force having a constant frequency, may not be generated for preventing its resonance with the intrinsic number of vibrations of the moving blade. Thus, in designing the vibrationproof strength of the steam turbine, only a harmonic exciting force having only an exciting force of 1/10 the nozzle wake exciting force to be considered and thus the design is made extremely easy.

CONSTITUTION:When a throttle valve 8 is closed in order to shift the accelerating or constant speed operation of the engine into the decelerating operation, vacuum in the suction air path 4 is increased and fuel, adhered to the internal surface 11a of the porous pipe 11, is tried to suck it into the combustion chamber by one effort. At this time, a valve opening signal (a) is outputted from a control unit 17 to a vacuum control valve 16 based on the valve closing signal (b) from a throttle valve opening degree sensor 18. According to this method, the suction vacuum is introduced into the vacuum chamber 14a of a driving device 14 and the shutter valve 13 is closed through a diaphragm 14c and a rod 14d. Accordingly, the fuel adhered to said internal surface 11a is precluded from being sucked into the combustion chamber 3 directly. Then, the fuel is sucked out of the fine holes of the porous pipe 11 gradually and induced into the combustion chamber step by step in a small amount.

Title: Insulation gate type field effect semiconductor device
Inventor: YAMAZAKI SHUNPEI
IPC: H01L29/78
Filed: 1990-07-26
Abstract: PURPOSE:To minimize the generation of interface charge, facilitate anisotropic etching and manufacture by turning a projected region for the formation of a micro channel into rectangular shape and every side of it to (100) planes. CONSTITUTION:As a single crystal semiconductor substrate having planes (100), is selected for example, a silicon single crystal semiconductor having planes (100). A rectangular-shaped and projected region 35, when viewed from above, is formed by using a first photo mask. To prepare the device, preferably, photoresist 32 should be formed as a mask by anisotropic etching of a silicon single crystal substrate. Most importantly, this corner section must shows its vertical side sharply, say, at 90 deg. to the top of the substrate. The height of this projected region 35 is adapted to range from 0.5 to 4mum, for example, it is specified as 1.5mum. The rectangular projected region 35 allows its channel formation region to be (100) sides (<100> oriented 40). A parasitic prevention plane is also (010) sided (<010> oriented 40'). This construction makes it possible to reduce the fixed charge density at every side to about 1/2 compared with other crystal planes (11), and (111).
