Abstract: PURPOSE:To decrease defect density of GaAs thin film layer, e.g. by growing a silicon thin film layer prior to formation of semiconductor compound thin films such as GaAs on a silicon substrate, and then growing the semiconductor compound thin films without exposing the silicon substrate to the air. CONSTITUTION:A silicon substrate is mounted on a growing device, and hydrogen gas, as carrier gas, is heated to a temperature of 900 deg.C and kept at the temperature for about 30 minutes.

After that, the temperature of the substrate is lowered to 450 deg.C. At the temperature, TMC and AsH3 are supplied. GaAs continues to grow until the film thickness gets to 500Angstrom ngstrom, and then the supply of TMG is temporarily interrupted. After the interruption, the temperature of the substrate is raised up to 700 deg., and again TMG is supplied. After obtaining the desired film thickness of the GaAs layer, the supply of TMG is interrupted again, and the temperature of the substrate is made to fall down.

Title: Thin-film photoelectric conversion element
Inventor: SATO KAZUHIKO
IPC: H01L31/0224
Filed: 1985-05-23

Title: Gyroscope apparatus
Inventor: FUJIWARA JIYUNICHI
IPC: G01C19/08
Filed: 1979-08-30
Abstract: PURPOSE: To reduce the settling time, by using the gyroscope itself as the weight, decreasing the adjusting time through lifting up and down from remote location, and tentatively lowering the center of gravity externally.  
     CONSTITUTION: When the power supply is applied, AC is fed to two rolling wheels through the conductive waves of the inner and outer sphere to drive them. On the other hand, to adjust the position of center of gravity, when a given a voltage is produced at the potentiometer 37, the modulator 38 generates the modultion signal having the frequency corresponding to this voltage and feeds it to the primary side of the modulation transformer 36. The modulation transformer 36 amplitude-modulates the secondary output and feeds it in the inner sphere 2. This modulation component is converted into the voltage corresponding to the modulation frequency at the frequency-voltage converter 41 and fed to the comparator 40. The comparator 40 compares this voltage with the output voltage of the potentiometer 21 and produces the voltage of difference. This voltage is amplified at the servo-amplifier 42 to control the direction of rotation of the servomotor 17 and the rotation frequency.

Abstract: PURPOSE:To increase the yield of hydrogen per mole of methane 1 in an internal heat type reformer, and reduce the carbon dioxide in a cell waste gas by recycling only a part of the waste fuel gas in the outlet of a fuel cell body to the internal heat type reformer. CONSTITUTION:A starting fuel gas 1 such as methane is reformed into hydrogen and carbon monoxide by an internal heat type reformer 2. The carbon monoxide is modified into hydrogen by a carbon monoxide modifying device 3, and this hydrogen is used for generation in a fuel cell body 4 to generate a waste fuel gas 5 containing hydrogen, carbon monoxide and carbon dioxide. A part (about 10-30 %) of the gas 5 is recycled to the reformer 2, the hydrogen and carbon monoxide are used as a part of the reforming heat source in the reformer 2, and the carbon dioxide is reacted with methane to generate hydrogen. Since the hydrogen yield per mole of methane 1 in the internal heat reformer is thus increased, the efficiency of the generating system is improved, and the exhaust quantity of carbon dioxide can be also reduced.

IPC: F24S90/00
Filed: 1978-09-08
Abstract: PURPOSE: To save power by separating water-lifting pump from water circulation pump whereby water could be circulated by a water circulation pump of small capacity.  
     CONSTITUTION: Water circulation pump 5a starts operation by the openings for an amount of the prescribed temp. at the upper 16a and the lower 16b temp. difference sensors, and because at that time, water surface switch 11 is closed, solenoid valve 8 is opened which closes the pressure switch 7. By this action, hot water pump 4 starts operation which makes water pour into the water bowl 10 thru return pipe 13 after filling the solar heat collector 1. When the water bowl 10 is fully filled, its water surface reaches the tip of the return pipe 13 and the solenoid valve 8 is closed. This action increases the pressure within the hot water pipe 17 and stops operation of the hot water supply pump 4. Water circulation to be performed afterward is regulated by the water head difference between the surface of the water bowl 10 and the hot water tank 2a, and the water circulation is performed by the operation of the pump 5a whose capacity is only larger than the aggregated sum of the resistances of water passages concerned, and the required electric power is saved to a great degree.

Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To shield a part of the visibility while ventilation and translucency is kept by providing a face plate which is erected between adjacent pergola long members, and capable of shielding a part of the visibility from the outdoor side to a building frame. SOLUTION: A face plate 30 capable of shielding a part of the visibility is erected between adjacent pergola long members 20. The face plate 30 is formed of the lattice shape by a large lattice 32 and a small lattice. The small lattice is formed close to the building frame side rather than to the large lattice 32, and the building frame side is more difficult to see through the face plate 30 from a counter building frame. Thickness is reduced more and taper is reduced more to the end as a transverse member for the large lattice and a longitudinal member for the large lattice are located closer to the counter building frame side. When viewed through the face plate 30, the visibility from the opposite side is the range of the narrower angle.  Upper and lower ends of the face plate 30 are held by upper and lower metal frames 51, 52, and fixed to the members 20 to control the stress concentration. Privacy can be protected thereby.
