Title: Balanced modulator
Inventor: YAMAHA YOSHIRO
IPC: H03C1/54
Filed: 1992-12-04
Abstract: PURPOSE:To suppress an undesired signal due to an offset voltage with simple circuit configuration by employing one operational amplifier so as to avoid the production of a difference from the offset voltage between an inverting signal and a noninverting signal. CONSTITUTION:Only capacitors C3, C4 among capacitors C1, C2, C3, C4, C(=CA+ CB) are charmed by an input signal VS with switches phiM, phi1 closed and when a switch phi2 is closed, charges of Q=2CVS from 2nd and 4th switched capacitors (SC) and charges of Q'=-CVS from the 1st SC are summed at an inverting input terminal of an operational amplifier 1 and an output signal VS is obtained at an output terminal VO. The capacitor C4 is charmed by the input signal VS with the switch phiM opened and with the switch phi1 closed and when the switch phi2 is closed, charges of Q=CVS from the 2nd SC and charges of Q'=-2CVS from the 1st and 3rd SC are summed at the inverting input terminal of the operational amplifier 1 and an output signal -VS is obtained at the output terminal VO. Since the one operational amplifier is employed, no difference of the offset voltage between the voltages VS and -VS is produced.

Abstract: PROBLEM TO BE SOLVED: To suppress the initiation of a crack by containing fibrillar Aramid short fiber at specified parts by weight in a rubber composition forming a tread part, and preventing the fibrillar Aramid short fiber from working as a foreign matter. SOLUTION: A rubber composition used for tread rubber 6 contains fibrillar Aramid short fiber 7 compounded at 0.3-20.0 pts.wt to 100 pts.wt. of rubber. The fibrillar Aramid fiber is also called pulp-like Aramid fiber. Para-Aramid fiber is rubbed by a specified method to form the surface of fiber into fibrils with a large number of whisker-like fine fibers of about 1-2 mm formed on the surface, and the fiber diameter is smaller than normal short fiber not formed into fibrils. Adverse effect of the fibrillar Aramid fiber 7 working as a foreign matter in the rubber composion in the case of being compounded is therefore small so as to suppress the initiation of a crack easily initiated when rubber is deteriorated by ozone.

Filed: 1992-12-04
Abstract: PURPOSE:To perform thermal transfer printing in multiple colors on a piece of recording paper having a low-smoothness and eliminate the need of an ink sheet which turns into refuse, by a method wherein solid inks are melted by the heat of a thermal head and images in two or more colors are once transferred and superimposed on an intermediate transfer medium and then transferred on the recording paper at a time. CONSTITUTION:A thermal printer is provided with an intermediate transfer medium 28, an ink cartridge 21 where two or more solid inks 22-25 are slowed and a thermal head 27. The thermal transfer printing is carried out in two steps: first and second transfer steps. In the first transfer step to form images on the intermediate transfer medium 28, a heat energy is imposed on the intermediate transfer medium 28 from behind by the thermal head 27 to melt the solid inks which are in contact with the surface of the intermediate transfer medium 28. In the second transfer step, the image on the intermediate transfer medium 28 is retransferred on a piece of recording paper 29. The ink cartridge 21 contains two or more solid inks 22-25 and is turned so that other contact faces of the ink cartridge 21 are brought in contact with the intermediate transfer medium 28. Thereby, images in two or more colors are superimposed on the intermediate transfer medium 28 and formed into a multi-color image. After that, the multicolor image is transferred on the recording paper 29 in one transfer step.

Abstract: PURPOSE:To eliminate limit on the design of a circuit by respectively inserting Pch (P channel) transistors between the respective source electrodes of two Pch transistors for feedback and a power source, and turning ON/OFF the transistors by two pairs of clocks. CONSTITUTION:Between Pch transistors 31 and 32 to feed back the Lo outputs of inverters 21 and 22 to an input terminal 5 and a power source 4, Pch transistors 51 and 52 are inserted to be respectively turned ON/OFF synchronously with the clocks. Since the added transistors 51 and 52 are the Pch transistors, they ate turned OFF when the data are read and two-phase clocks phi1 and phi2 are Hi. Then, when the data are read, the Pch transistors 31 and 32 are turned OFF without fail by the operations of the added Pch transistors 51 and 52. Therefore, it is not necessary to set the current supply ability of the Pch transistors 31 and 32 within a limited value and thus, the degree of freedom for the circuit design is increased.

IPC: H05B41/24
Filed: 1989-12-15
Abstract: PURPOSE:To prevent an excessive stress from being applied to circuit elements by providing a power source voltage fluctuation compensating circuit with a means for inverting a direction for changing an oscillation frequency at a constant frequency higher than a resonance frequency of an inverter circuit when power source voltage drops. CONSTITUTION:A power source voltage fluctuation compensating circuit 3 connects a serial circuit of resistors R1, R'1 between an (a) point of a current mirror circuit composed of transistors Q3, Q4, etc., while a diode D1 is connected between connection of this serial circuit and a collector of the transistor Q4. Therefore when power source voltage drops, it inverts a direction for changing an oscillation frequency at a constant frequency higher than a resonance frequency of an inverter circuit. Thus while a function for compensating a power source fluctuation is not lost, even if an extreme drop in voltage or an instantaneous power failure occurs, the direction of change in the oscillation frequency can be inverted before the oscillation frequency reaches the resonance frequency of a resonance circuit so that an excessive stress may not applied to circuit elements.

Abstract: PURPOSE:To compensate a portion of slippage with an actual air quantity to be produced at the time of transient driving in an accurate manner by reducing a reflecting degree of the last detected value in the moderated value when each size of this moderated value and this time detected value goes into reverse as to the intake air quantity. CONSTITUTION:A control unit 50 operated such a value as processed so as to reflect the last detected value to this time detected value detected by an air flow sensor 31 as far as the specified rate. Here, when each size of the actual detected value by the air flow sensor 31 and the moderated value goes into reverse, it is compensated so as to reduce a reflecting degree of the last detected value. With this constitution, since the moderated value is approximated to this time detected value and it is compensated so as to check a slippage range of the moderated value to smallness, any slippage in an air-fuel ratio with a time leg due to moderate processing after an overshoot being produced at time of transient driving and the convergeability are thus preventable from worsening.
