Abstract: PURPOSE:To lower a consumed power, to make compact a circuit scale and to decrease a loss in the circuit by using an FET in a PSK demodulation circuit in a transmission line of a responding system using the same carrier wave. CONSTITUTION:In a strip line, in accordance with a termination condition, a reflected wave having a different phase with respect to an incident wave is produced. When the termination is opened, the reflected wave of the in-phase is produced and in the case of a short circuit, the reflected wave of an opposite phase having a phase difference of 180 deg. is generated. Accordingly, when a control signal is applied to an input terminal 5 in a response station, a control voltage is impressed to a gate G of the FET 8 through a high frequency noise removing low-pass filter 4 constituted by the strip lines. Thereby, in the termination of a matching section 7 constituted by the strip lines with respect to the incident carrier wave from a base station of the response system receiving from an antenna 1, correspondingly to an inoperative time or an operative time of the FET 8, the in-phase or the opposite phase reflected wave is generated.

Title: Controlling system of moving machine having backlash
Inventor: FUTAMI SHIGERU
IPC: G05B13/00
Filed: 1982-06-08
Abstract: PURPOSE:To ensure the highly accurate control with no shock for a moving machine having a backlash, by adding a function to obtain a boundary line with which the desired time is shifted on the position and speed phase surfaces from the changing point of acceleration and deceleration and then performs a gap control with the boundary line used as the boundary conditions. CONSTITUTION:When a gap due to a backlash is set at the acceleration side during a start, switch devices 14 and 15 are switched toward 14b and 15b by a deciding device 13. Thus the acceleration is controlled for a motor M. Then the device 15 is switched to a switch 15a to perform the deceleration control. Thus the gap is set at 0. When the device 15 is switched to a switch 15b, the motor M receives the acceleration control. Then the position and speed reach the value on an auxiliary switch curve with which the time is shifted early. Thus the position and speed are switched to perform the deceleration control. When the position and speed coincide with the value on the switch curve, the acceleration control is perfomed to set the gap of the deceleration side at 0. At this time point, the device 14 is switched to continue the deceleration control up to the target value.
