Title: Amplifier
Inventor: MORI TOSHIKI
IPC: H03F3/45
Filed: 1978-06-23
Abstract: PURPOSE:To suit two FETs, constituting a differential couple, to be IC-implemented with the number of terminals reduced, by fixing output direct-current potentials by making source and drain currents different when pinch-off voltages are equal each other with zero gate voltage. CONSTITUTION:To the gate of input-side FETT3 constituting a differential couple together with FETT4, an input signal is applied from input signal supply 301 and the direct-current potential of this input signal is equalized to that of negative voltage supply terminal 304. Then, FETs T3 and T4 are made into a differential couple with source and drain currents different each other when pinch-off voltages are equal while gate voltages are zero, so that the output direct-current potential can be determined without using any capacitor. Consequently, the both can be suited to be IC-implemented by reducing terminals in number.

Abstract: PURPOSE:To maintain a constant fixing strength regardless of the thickness of paper to be printed by providing pressuring force on a heating roller by a spring through a pressuring roller as well as varying fixing pressure responding to the thickness of the paper. CONSTITUTION:The paper is inserted in between a heating roller 1 and a pressurizing roller 2, and printing is carried out by fixing an electrophotograph to this paper. At this time, pressurizing strength is provided to the pressuring roller 2 with the spring 4, and with the variation in compressed quantity of this spring 4, the size of the pressurizing strength is varied. By sliding a sliding part with taper 5 in the direction of an arrow 6, the compressed quantity of the spring 4 is varied, and the pressurizing force of the roller 2 to the heating roller 1 is varied. Because the pressurizing force of the roller 2 is varied responding to the thickness of the paper, even when the thickness of the paper varies, a constant strength can be maintained.

Title: Control device for automatic transmission
Inventor: NOBEMOTO HIDETOSHI
IPC: B60W10/10
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide the high gear ratio of a transmission as much as possible and improve engine fuel consumption by correcting the gear ratio of a transmission toward a higher level by the preset value, upon the detection of the unstable combustion state of an engine. SOLUTION: When the unstable combustion state of an engine is detected with an unstable combustion means 121, a gear ratio corrected toward an increase with a gear ratio correction means 122 is stored as a High ratio limit value rhigh in a memory means 123. When a control unit starts or stops an operation, the High ratio limit value rhigh of a High ratio limit map is initialized. Furthermore, when the travel of a vehicle is in unstable travel state, a target engine speed is calculated. Also, the number of pulses is calculated so as to keep an actual engine speed equal to the target engine speed, and pulse signals are subsequently outputted, thereby applying feedback control to the gear ratio of a transmission 12. According to this construction, the application of the High ratio range to the transmission 12 is facilitated, and the fuel consumption of the engine is thereby improved.

IPC: C22B7/00
Filed: 1984-04-17
Abstract: PURPOSE:To provide the titled regenerated raw material for melting which is easy to handle and yields a molten metal having high quality at a good yield by mixing much aluminum swarf and magnesia cement and solidifying the mixture. CONSTITUTION:The mixture composed of about 15-1% outer percentage magnesium oxide powder and about 15-1% magnesium chloride as well as about 1-10% water are added and mixed to and with aluminum swarf and the mixture is put into dies and is molded under pressure. The molding is put into a thermostatic furnace kept at about 50-200 deg.C and is dried for about 20-90min, by which the molding is dehydrated. Many small pieces of the aluminum swarf are thus solidified with the magnesia cement formed by the interreaction of the magnesium oxide and magnesium chloride as a binder, by which the regenerated raw material for melting is obtd.

Title: Semiconductor circuit
Inventor: SUGANO KAZUHIRO
IPC: H03F3/34
Filed: 1990-03-27
Abstract: PURPOSE:To reduce an input offset voltage by providing a transistor(TR) whose emitter is connected to a current output terminal of a current mirror circuit and whose collector is connected to an output terminal of a differential amplifier circuit so as to make a level of a current input terminal of the current mirror circuit substantially equal to a level of an output terminal of the current mirror circuit. CONSTITUTION:A potential of the collector of a TR Q2 depends on the base voltage of a TR Q5, and the base voltage is a voltage resulting from a power supply voltage VCC subtracted by two base.emitter voltage (2XVBE). Since the collector potential of the TR Q2 is boosted by the base.emitter voltage VBE from the base voltage of the TR Q5, then equal to (VCC-VBE) and the collector.emitter voltage of both the TRs Q1, Q2 is equal to each other. Thus, no early effect is caused and the collector current of the TR Q1 and that of the TR Q2 at no signal input are equal to each other. Thus, the matching of the collector current of the TRs Q3, Q4 being components of a differential input stage is improved by the operation above and an input offset voltage is decreased.

Abstract: PROBLEM TO BE SOLVED: To surely solder a circuit board to a case main body with good workability on a shield case which loads the circuit board soldered with the case main body. SOLUTION: In a shield case, a soldering part 12A is integrally installed in a case main body 8 and a circuit board 9 is soldered/fixed to the case main body 8 with the soldered part 12A.
