IPC: C22C14/00
Filed: 1988-02-06
Abstract: PURPOSE:To manufacture hydrogen storage alloy powder without needing activating treatment at low cost by coating rare earth metal group hydrogen storage alloy on the outer surface of Ti base hydrogen storage alloy powder. CONSTITUTION:On the outer surface of the Ti base hydrogen storage alloy powder, such as typically TiFe, TiMn, the rare earth metal group hydrogen storage alloy, such as typically LaNi5, MmNi5 is coated by using spattering, etc. Then, the coating of the rare earth metal group hydrogen storage alloy may be not always perfectly coated, but the higher the coating ratio is, the more favorable the hydrogen storage alloy is. By this method, the hydrogen storage alloy powder, which can very quickly absorb a large quantity of hydrogen and easily and quickly discharges hydrogen with only a little heating, is obtd.

Title: Fuel cell power generation system, its operating method, and operation control method for it
Inventor: TAKE TETSUO
IPC: H01M8/04
Filed: 1994-02-24
Abstract: PURPOSE:To carry out the valve operation tests without changing over to another fuel by performing the control upon instal ling a bypass line and flow control valves additionally in one of the fuel systems. CONSTITUTION:The operation tests for flow control valves 3. 6 for fuel change-over are made during power generation with urban gas by putting a control device 51 in the fuel change-over test mode. With a signal given by the control device 51, a valve 47 on a bypass line 48 is opened, and at the same time, valves 32, 52 are closed while a valve 10 is opened. The gas 4 is passed through the line 48 and supplied to a desulfurizing device 7, and the power generation goes on. Because the valve 32 is closed, a pressure sensor 5 senses the drop of the supply pressure and gives a signal to the control device 51. The device 51 receives the signal, and closes the valve 6 while opens the valve 3. Liquefied propane gas is combusted by a burner 9 of a reformer device and not used in the power generation. With controlling by the device 51, the valves are restituted to the condition before the opening/closing test, i.e., into the steady generating mode. The gas 4 is sent from the normal supply line via the valve 6 and supplied to the desulfurizing device 7, and power generation with gas 4 goes on without interruption.

Title: Manufacture of photoconductive thin film
Inventor: HARADA YOICHI
IPC: H01L31/0248
Filed: 1989-02-06
Abstract: PURPOSE:To obtain easily a thin film whose Cu concentration can be controlled correctly and is distributed uniformly by adding CuCl2 to a target principally composed of CdS, CdSe or a solid solution of CdS/CdSe. CONSTITUTION:A thin film is formed on an insulative substrate by a sputtering process using a target principally composed of CdS or CdSe, or a solid solution thereof (CdS/CdSe) and additionally containing a trace quantity of CuCl2, and the film is thermally treated in an atmosphere containing CdCl2. According to this method, the film contains Cu at a concentration substantially proportional to the concentration of CuCl2 at the time of preparing the evaporating source and, therefore, the concentration of Cu can be controlled with good controllability. Consequently, control of Cu concentration in the sputtering process can be performed more correctly and distribution of the concentration can be made uniform.

Title: Optical disk record reproducer
Inventor: NAKANE HIROSHI
IPC: G11B27/36
Filed: 1983-02-21
Abstract: PURPOSE:To detect accurately the position of a disk where a dropout is produced by lowering the open loop gain of a tracking control system and at the same time increasing the detection sensitivity after estimating the position where the dropout of the disk is produced. CONSTITUTION:When the first dropout is detected under reproduction, a level comparator 26 inverts the level of an output terminal. In this case, the output signal of the comparator 26 is delayed by a delay circuit 44 by a period needed for about one revolution of a disk. Therefore switching circuits 35, 40 and 41 are driven when the next dropout is produced to lead out the signals to be supplied to each terminal (b). Thus the next dropout is estimated and each open loop gain is kept at a low level for a fixed period, and at the same time the sensitivity of the comparator 26 is increased by a reference voltage generator B43. Therefore the dropout compensation is secured with high quality when the 2nd and subsequent dropouts are produced, and at the same time the position of the disk dropout is accurately detected.

This retrieved data is turned into the segment data of the spots, lines, circles, circular arcs, etc., and an error component alpha is added to or subtracted from the maximum and minimum positions of coordinates occupied by each segment. So that an area including the segments is set. When the coordinate position of the cursor 19 is included in the set area, the distance D between the mouse coordinate position and a segment is compared with the component alpha. Then, the record number of the NC data is acquired and the corresponding NC data is displayed on the screen 15F when alpha>D is satisfied.

SOLUTION: A saturable absorption layer 203 is arranged in a position coinciding with the peak of the intensity of light in a distributed Bragg reflector or the like where the periodic distribution of the refractive index starts with a low-refractive index layer 201. When an optical pulse having a wide pulse width is made incident on this distributed Bragg reflector, the intensity of the optical pulse is increased by the low-refractive index layer 201 and a refractive index layer 202, and a part to be the leading edge of the optical pulse with respect to the time disappears by the saturable absorption layer 203. Thus, the pulse width is compressed only with one reflection.
