Patent JP-S6292312-A (JP)
Title: Preparation of compound semiconductor substrate
Inventor: SHIMIZU MASABUMI
IPC: H01L21/205
Filed: 1985-10-17
Abstract: PURPOSE:To form easily a single crystal layer of compound semiconductor on a Si substrate of large area, by forming a preliminary deposition layer on a Si substrate by plasma vapor growth, and forming a compound semiconductor substrate thereon. CONSTITUTION:A Si substrate 3 is mounted between high frequency electrodes 6 of a plasma reaction vessel 7, and the substrate 3 is heated by a heater 8. Reaction gas is introduced into the vessel 7 through a reaction gas inlet 9. Deposition is progressed in plasma discharge by a high frequency power source 10, and a polycrystalline GaAs approximate to amorphous state (preliminary deposition layer 5) is formed on the substrate 3. After the plasma discharge is interrupted, the temperature of the substrate 3 on which the deposition layer 5 is formed is raised at 650 deg.C, and this state is kept for 10min. After that, the reduced pressure MOCVD growth is performed at a pressure of about 100Torr, and a GaAs layer (compound semiconductor layer 1) is formed. A single crystal layer of compound semiconductor is easily formed on the substrate 3, thereby.

Title: Fuel cell
Inventor: IYASU KYOTARO
IPC: H01M8/04
Filed: 1986-10-02
Abstract: PURPOSE:To prevent the corrosion and the deterioration of pipings and fittings, and to acquire a fuel cell of a high reliability, by making the filling rate of a metallic wool at the gas inlet side higher than that at the gas outlet side. CONSTITUTION:In a scrubber 4, metallic wools 5a to 5c to remove the phosphoric acid are filled to make the wool diameters from the wool 5a at the gas inlet side to the wool 5c at the gas outlet side smaller in order. Since the phosphoric acid is at a high temperature, it reacts instantly making a phosphate, which is accumulated over the metallic wool 5a. Because the diameter of the metallic wool 5a is about 1 mm, for example, the phosphate never closes off its porousness. On the other hand, since the diameter of the metallic wool 5b is about 0.5 mm, for example, the majority of the phosphate which is not removed at the wool 5a is removed there. Finally, the metallic wool 5c contacting to the metallic wool 5b has the smallest diameter, about 0.2 mm, for example, and the phosphate is removed there perfectly, and then the gas is exhausted from the outlet piping 6b.

Title: Roll rigidity control equipment for vehicle
Inventor: SUGASAWA FUKASHI
IPC: B60G17/016
Filed: 1983-12-12
Abstract: PURPOSE:To improve stability in steering and ride comfort by means of constitution in which roll rigidity is increased by controlling roll rigidity variable mechanism as soon as the amount of steering per unit time, which is calculated from detected steering angle, exceeds the predetermined value. CONSTITUTION:Steering angle theta and vehicle speed V are detected by a detector 2 and a detector 4 respectively and input into a control equipment 5. The control equipment 5 processes the said data on theta and V in accordance with a predetermined program and selects both the amount of steering angle for judgment DELTAtheta and a variable m. Then, based on the most recent steering angle variable thetan that has been stored, the control equipment 5 specifies the previous steering angle variable thetan-m that is ahead of the present variable by m times. Next, the equipment 5 calculates an additional steering angle thetan-thetan-m per unit time. Then, this thetan-thetan-m is compared with amount of steering for judgment DELTAtheta. For thetan-thetan-m>DELTAtheta, a damping force control signal is output to damping force variable shock absorbers 7a-7d, thereby increasing the roll ridigity. With this constitution, both ride comfort and steering stability can be improved.
