Title: Fuel cell power generating system
Inventor: KAMOSHITA TOMOYOSHI
IPC: H01M8/06
Filed: 1989-03-23
Abstract: PURPOSE:To make a system follow to quick increase or decrease of load current without use of an auxiliary storage battery by installing a circulation line connecting fuel gas supply line and a fuel exhaust gas line, and further installing a fuel gas storage line branched from the gas supply line. CONSTITUTION:When load current is sharply increased, a fuel cell can follow it because fuel gas equivalent to 100% load current flows within the fuel cell, but since the inner volume of a fuel gas circulation line passage 6 is not large, a valve 37 is opened and fuel gas in a fuel storage tank 16 is temporarily supplied to the fuel cell through a pressure control valve 15 and a stored fuel supply passage 13. Although a reformer 9 must reform increased fuel gas and must supply reformed gas to the fuel cell 1, since off-gas from the fuel cell 1 cannot follow immediately, fuel gas used in a burner 10 is temporarily supplied by quickly opening a valve 38 from the fuel storage tank 16 through the pressure control valve 15 and the stored fuel supply passage 13 to keep heat balance in the reformer.

Title: Method for annealing stainless steel without occurrence of surface roughening
Inventor: YAMAZAKI SHINJI
IPC: C21D1/76
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To stably obtain a stainless steel free from surface roughening by previously determining the min. oxidation power to obviate the occurrence of the surface roughening and executing annealing in an atmosphere contg. gaseous nitrogen while controlling the compsn. and dew point of the gas in such a manner that the oxidation power higher than this oxidation power is attained. SOLUTION: The annealing conditions are previously empirically determined in such a manner that the surface roughening by nitriding does not arise at all in the stainless steel. The oxidation power expressed by Gibbs free energy ΔG is previously calculated from the determined annealing conditions. The annealing conditions with the actual machine are then so controlled that the oxidation power ΔG determined from the annealing conditions with the actual annealing equipment is kept smaller than the oxidation power ΔG at all times. At this time, the annealing temp. is relatively little in the degree of freedom in change and, therefore, the control of the dew point and the control of the components (the concn. of hydrogen in the case of the gaseous mixture composed of the hydrogen and nitrogen) of the atmosphere gas are preferably executed.  As a result, the nitriding of the surface of the stainless steel at the time of the annealing is prevented with good accuracy.

Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an SOI substrate which is helpful in elimination of resources and reducing the cost and, at the same time, a method for manufacturing low-cost photoelectric conversion device by saving resources such as the solar battery, etc., by which substrates can be separated completely by using a porous Si layer and the need of strong adhesion between the substrates and a jig can be eliminated. SOLUTION: In a method for manufacturing thin film, Si thin films are formed by separating the nonporous Si layer 2 and less porous Si layer 4 of a substrate, in which a porous Si layer 3 is formed on the nonporous Si layer 2 and a less porous Si layer 4 is formed on the porous Si layer 3, by using the layer 3. In separating the layers 2 and 4, heat is preferentially transferred to the layer 3 by winding a metallic wire 10 around the side face of the substrate and generating heat from the wire 10 by making an electric current flow to the wire 10. Then, an SOI substrate is manufactured from separated substrates 4, 7, and 6 and the nonporous Si layer 2 is again utilized for the manufacturing process of the SOI substrate.

Title: Disk brake
Inventor: AOYANAGI SHINJI
IPC: F16D55/224
Filed: 1995-03-06
Abstract: PURPOSE: To restrain a caliper from the generation of flat surface turning moment and reduce the uneven wear of a pad by extending the length of a main pin on the rotor rotation side of a guide pin supporting movably the caliper to span the rotor and setting the main pin length longer than that of the opposing surface parts of an outer pad and the rotor. CONSTITUTION: In breaking operation, an inner pad 22 is pressed against a rotor 10, and an outer pad 26 is pressed against the rotor 10 through a caliper 12 by press reaction. The breaking torque of the outer pad 26 is then transmitted through a caliper claw 24 to a main guide pin 16 to be supported by a vehicle body. Then, the length of the main guide pin 16 is set longer than that reaching the outer surface of the rotor 10, and the respective main and sub-guide pins 16, 18 are located outside the braking center of the outer pad 26. Thus, the torque is tramsmitted to the calilper 12 around the guide pin 16 to press both pins 16, 18 so that vibrations are restrained to prevent uneven wear.

Title: Lens driving device
Inventor: NII TAMOTSU
IPC: G02B7/04
Filed: 1983-04-25
Abstract: PURPOSE:To simplify the structure, to reduce the processing cost and to make a device compact by repelling a permanent magnet in the end position in the direction of the optical axis with an electromagnet in a lens supporting frame. CONSTITUTION:If power is so supplied to an electromagnet 8 of the second lens group 3 that the side of the third lens group 4 is the S pole when the second lens group 3 is free, the group 3 is moved to the side of the group 4 because the electromagnet and a permanent magnet 6 of the group 4 attract with each other with N and S poles and the electromagnet and a permanent magnet 5 of a lens group 2 repel with each other with N poles. Consequently, when a current having the opposite polarity is flowed to the electromagnet 8 of the group 3, the group 3 is moved in the opposite direction to the side of the group 2. Even if the current is cut off after the group 3 is attracted to the group 2 or 4, the group 3 is fixed in the moved position because an iron core 8b is attracted to the magnet 5 or 6. The current is flowed to electromagnets and permanent magnets facing each other to generate a repellent (or attraction) in this manner, thereby driving lenses.

Title: Secondary-air controlling system
Inventor: OOTSUKI HIROMI
IPC: F01N3/22
Filed: 1979-06-08
Abstract: PURPOSE: To control a secondary-air control valve optimally according to the level of engine load, by providing an orifice passage in a signal circuit connecting a pressure source producing a pressure corresponding to the engine load and a pressure chamber of the secondary-air control valve, and thereby controlling the opening area of said orifice passage.  
     CONSTITUTION: When secondary air is supplied to exhaust port 10 by opening secondary-air control valve 6, electrmagnetic valve 8 for transmitting negative pressure to pressure chamber 22 is energized. When ports 8a and 8c of the valve 8 are communicated with each other, pressure in intake pipe 2 of internal combustion engine 1 is transmitted to vacuum sensing port 21 via vacuum transmission control valve 9. When the engine load is low and partial vacuum in intake pipe 2 is fairly high, the partial vacuum is transmitted to thin plate 14 via valve 9, port 18, diaphragm 10 and shaft 12, so that the thin plate 14 is turned upward. Resultantly, the opening area of orifice passage 15 is reduced and pressure in intake pipe 2 is thus transmitted to pressure chamber 22. Therefore, pressure in pressure chamber 22 is lowered gradually and valve 6 is opened slowly.
