Abstract: PURPOSE:To use economically one button as both a pause button and a redialing button and to eliminate a trouble in operation by providing an on-hook and off-hook discriminating circuit to the pause terminal of a dial circuit. CONSTITUTION:A source voltage VDD is supplied to the other input terminal of an IC 2 through HS 4 in an on-hook state and the output goes up to a high level to make a pause mode effective. When the combined-use button 3 is pressed in this state, the highlevel signal is sent to the dial circuit LSI 1 through the combined-use button 3 and the dial circuit LSI l sets the pause time at the time of abbreviated dialing registration. Further, the other input terminal of the IC 2 is grounded through the HS 4 in an off-hook state and the output goes down to a low level to make the pause mode ineffective, so that a redialing terminal 6 is made effectively. When the combined-use button 3 is pressed in this state, the dial circuit LSI 1 judges redialing.

CONSTITUTION:In order to turn off the PNPN switches, S1, S2 a switch S11 is turned on and a switch S22 is turned off. When the voltage level at an anode terminal A1 is higher than a negative voltage source V2, a current I2 flows as a base current of a PNP transistor (TR)Q3 and the TRQ3 is turned on. As a result, a base and an emitter of TRs QN1, QN2 are short-circuit respectively, the TRs QN1, QP2 are turned off and the PNPN switches S1, S2 are turned off. The collector voltage and the emitter voltage of TRs Q3, Q4 are not effected from the voltage of terminals A1, K2 during this period. That is, the base- emitter voltage of the TRs QN1, QP2 is kept to zero voltage and the off state of the PNPN switches S1, S2 is maintained. Since the PNPN switches S1, S2 are turned off, the current sources I1, I2 are not leaked external via the terminal A1, K2.

IPC: B60C23/14
Filed: 1978-07-14
Abstract: PURPOSE: To accomplish indirect air pressure loading very quickly at a high efficiency by charging the primary pressure from the compressor into tire after once stroed into a tank.  
     CONSTITUTION: The primary pressure from a compressor COP is stored into a tank T 1  through a direction controlling valve A being pressed with a spring pilot a while sent to a fixed pressure regulating valve 11 (high pressure) and a preset pressure regulating valve 11. The pressure of the valve 10 enters a tank T 3  through a direction controlling valve B and actuates a charging pilot b of the valve A to switch the valve A. In this manner, the internal pressure of the tank T 1  is fed into a tire TA1. At the same time, the primary pressure of the compressor COP enters the tank T 2  through the control valve A and actuates a fixed pressure pilot d to exhaust the pressure of the tank T 2  while the pilot b returns to the original position by a pilot a. When the tire pressure reaches a preset level by repeating this procedure, pilots b and c are balanced and the action of the direction controlling valves B and A is halted.
