Title: Production of synchronizer ring made of brass type copper alloy for automobile gearbox, excellent in seizure resistance
Inventor: KOBAYASHI MASAO
IPC: C22F1/00
Filed: 1994-10-14
Abstract: PURPOSE: To produce a synchronizer ring for automobile gearbox, excellent in seizure resistance, by subjecting a brass type copper alloy stock, having a matrix structure composed of α+β' phase or β' phase, to finish machining into the prescribed shape and then to annealing at specific temp. CONSTITUTION: An ingot of a brass type copper alloy, which has the prescribed composition consisting of Zn, Al, Ni, Ti, Mg, etc., and Cu and also has a structure composed of α+β' phase or β' phase, is extruded, hot-forged, and then finish-machined into the prescribed shape. The resultant synchronizer ring having >=about 240Hv Vickers hardness is annealed at 300-500 deg.C. By completely removing this annealing working strain, Vickers hardness is reduced to about 170-220Hv. By this method, the synchronizer ring made of brass type copper alloy for automobile gear, excellent in seizure resistance and having long service life, can be obtained.

IPC: H04N5/361
Filed: 1990-10-17
Abstract: PURPOSE:To obtain a signal suppressing an FPN at a dark state stably by reading a 1st half signal for one horizontal scanning period, resetting a stored charge, reading the signal again for a latter half, matching the timing of both read signals at an external circuit and applying subtraction processing to the signal without no photo charge from a signal in response to the photo charge. CONSTITUTION:A signal in response to a photo charge by one horizontal picture element string is read for a first half for one horizontal scanning period by applying high speed horizontal scanning to a solid-state image pickup element 1 and the stored charge is subject to high speed horizontal scanning again to read a signal by a same horizontal picture element while the stored charge is reset simultaneously or being reset for the latter half. A memory control section 12 is subject to time axis conversion by controlling a phase of a memory read pulse, the result is D/A-converted by D/A converters 9, 10, resulting in obtaining a signal B by a photo charge and a signal C at a dark state returned to the usual time axis. Then the signal B by the photo charge and the signal C at the dark state are inputted to a subtractor 11, in which the signal C is subtracted by the signal B by the photo charge to obtain a video signal D in which the FPN at dark state is suppressed is obtained.

IPC: G01N15/14
Filed: 1994-11-11
Abstract: PURPOSE: To obtain a charge distribution measuring apparatus for particle in which the measurement of charge distribution for zero point correction can be carried out accurately. CONSTITUTION: Particles 45 are fed downward toward a measuring cell 4 and subjected to an electric field in the way of running. Shift of the particle from a predetermined direction or the shifted moving speed is then detected and a charge distribution is measured based on the detection output.

Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To shorten a charging time by charging a plurality of batteries simultaneously with charging power of one battery without changing the weight and external dimensions of a charging device. SOLUTION: Based on the charging current of a battery 71 obtained through a detecting resistor 61, an OP-amp 521 and an A/D converter, an operating means 4 calculates the charging current of a battery 72 in such a way as to keep electric energy constant.

Title: Output buffer circuit
Inventor: SAKURAI MIKIO
IPC: H03K19/0175
Filed: 1993-11-08
Abstract: PURPOSE:To reduce the through current of an output buffer by providing another transistor for reducing the potential of the gate of a transistor to output low-order data corresponding to the control signal of the gate of a transistor to output high-order data. CONSTITUTION:A first driver transistor TR is correspondent to an NMOS TR 2 and a second driver transistor is correspondent to an NMOS TR 3. In this case, an NMOS TR 7 is provided to turn the potential of a node B to 'L' while receiving the signal of a node A. With the operation of this NMOS TR 7, namely, while receiving the potential of the node A turned to 'H' at a gate potential, the NMOS TR 7 is turned to a conducted state, and the node B and a ground potential node are conducted. Accordingly, although a capacitor 6 is provided, the node B is speedily completely turned to 'L' at prescribed timing. Therefore, since the time zone when the NMOS TR 2 and 3 are simultaneously turned on are extremely shortened in comparison with the conventional circuit, the through current at the output buffer is considerably reduced as well.
