CONSTITUTION:In the case of running right/left wheels respectively on paved/ non-paved road surfaces, in/out moving to/from a cylinder of a piston rod 15 of a car height adjusting unit L10 is performed more frequently than that of a car height adjusting unit R10, to place a pump up flow amount of operating fluid in the unit L10 in a condition larger than that of the unit R10, but by a difference between high pressure operating fluid pressures in the units R10, L10, a high pressure operating fluid in the unit L10 passes through a high pressure communicating pipe 31 to flow into the unit R10, and a pressure is uniformly generated. Accordingly, no difference is generated between right/left car heights. The operating fluid, flowing from the unit L10 to the unit R10, passes through a low pressure communicating pipe 32 to return to the unit L10. When a vehicle is turned, an orifice 33 in the high pressure communicating pipe 31 suppresses a flow to prevent a rolling amount from increasing.

Abstract: PURPOSE:To prevent distortion in an output and to detect a signal correctly by inputting an input signal to a noninverting input of an operational amplifier of an inverting feedback circuit via a time constant circuit comprising a resistor A and a capacitor, a resistor B and two diodes connected in anti-parallel. CONSTITUTION:An input signal from an input signal terminal 1 is inputted to a noninverting input of an operational amplifier 8 of an inverting feedback circuit using resistors 2, 3 via a time constant circuit comprising a resistor 4 and an electrolytic capacitor 7. Furthermore, a series circuit comprising two diodes 6 connected in anti-parallel and a resistor 5 are connected between terminals of the resistor 4. When a fluctuation of the input signal is large, a voltage across the resistor 2 is high, the diode 6 is operated, and a combined resistance of the resistors 4, 5 is small, then the time constant is formed by the resistor 4 only and the capacitor 7. A reference voltage of the amplifier 8 is tracked early or slowly with the fluctuation in by the small or large time constant. Thus, distortion of an output signal being a square wave is prevented and the signal is correctly detected.

Abstract: PURPOSE:To interchange power between power sources having different frequencies by providing two synchronous machines connected in series and operating at least one of them as a secondary AC-excited synchronous machine. CONSTITUTION:A frequency converter is constituted as shown on the drawing. When power is fed from a 60Hz system to a 50Hz system through such frequency converter, a secondary AC-excited synchronous machined 12(hereinafter, referred to AESM) is connected to the 50Hz system whereas an AESM 13 is connected to the 60Hz system.
