Filed: 1991-07-09
Abstract: PURPOSE:To prevent the wrong detection by providing a synchronizing separa tion circuit having a clamping circuit of the slow responsiveness and a synchro nizing separation circuit having a clamping circuit of the fast responsiveness respectively. CONSTITUTION:A synchronizing separation circuit 1 has a clamping circuit 4 of the slow responsiveness, and a synchronizing separation circuit 2 has a clamping circuit 7 of the fast responsiveness. The circuit 4 is unable to secure a completely fixed DC level and therefore a timing error is caused to the synchronizing signal separated by the circuit 1. However, the noise component can be eliminated out of the output of the circuit 2. Meanwhile, a fixed DC component is secured by the circuit 7 and therefore no timing error is caused to the synchronizing signal separated by the circuit 2. Then the output of the circuit 1 is used as a clamping pulse to the circuit 7. Furthermore, the noise component is eliminated out of the output of the circuit 1 and the fluctuation of a clamping level is never caused by the noises in the circuit 2.

Title: Input signal buffer circuit
Inventor: HIRANO HIROSHIGE
IPC: G11C11/409
Filed: 1990-07-23
Abstract: PURPOSE:To enable operation at a stable input switching level over a wide range of power supply voltage by decreasing an input switching level when the power supply voltage becomes higher than constant voltage and increasing the input switching level when the power supply voltage is reduced with a power supply voltage detection circuit. CONSTITUTION:When the power supply voltage is, for example, more than 6.5V, nodes N1 and N2 are both 'H', a transistor Qp3 is turned off, and a transistor Qn3 is turned on. When an input signal A is 'L' or 'H', power supply voltage VCC is supplied only through a transistor Qp1 to the node of an output signal B, and since grounded voltage VSS is supplied through transistors Qn1 and Qn2, an input switching level is decreased. Next, when the power supply voltage is, for example, less than 3.5V, both of the nodes N1 and N2 are 'L', the transistor Qp3 is turned on, and the transistor Qn3 is turned off, and the input switching level becomes higher compared with when the power supply voltage is more than 3.5V or less than 6.5V. Thus, the operation at a stable input switching level over a wide range of power supply voltage can be performed.

Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a heat pump type air conditioner by controlling the opening of a flow adjustment means according to the output of a delivery temperature detecting means and controlling the flow rate of an engine cooling water flowing through an outdoor evaporator. SOLUTION: A flow control actuator 32 functioning as a flow adjustment means is provided in a hot water inlet of a sub-evaporator 8 and the opening of the flow control actuator 32 is controlled according to a compressor delivery temperature When the delivery temperature of a compressor 2 increases more than a prescribed value, it is so controlled that the hot water flow rate to the sub-evaporator 8 is reduced in the high temperature range. This constitution reduces the hot water flow to the sub-evaporator 8 in the high temperature range so as to reduce the heat absorption rate from the hot water or a refrigerant and moderate the increase in the cycle pressure and cycle temperature.  Therefore, the overshoot caused by ON-OFF control of the flow control actuator 32 can be prevented so that the cycle pressure, etc., are prevented from exceeding the control value and the reliability is improved.
