Title: Control of wiper
Inventor: TAKEDA NOBUHIRO
IPC: B60S1/08
Filed: 1980-12-19
Abstract: PURPOSE: To change over an operation mode of a wiper by means of one switch by providing a momentary switch and rendering one motion of the wiper for one operation of the switch made within a certain period or intermittent motions determined by the operation interval of the switch for two operations.   
     CONSTITUTION: When a momentary switch 19 for one or intermittent operation is depressed once, a mono-multiplexor outputs a signal H for 0.5 second. A relay Y 1  is actuated during the period and a contact point (y 1 ) is changed over to electrify a low speed brush of a motor M. Although the contact point (y 1 ) is instantly restored, a contact point (m) is remained so that the motor M is turned till a completion of one operation of a wiper. If the wiper 19 is not be redepressed within the 30 seconds pass after the initial depression, that is, after a lapse of 20 seconds, for example, the motor M is controlled in such a manner that intermittent operation of the wiper is thereafter made on the 20-second interval basis.

Abstract: PURPOSE:To inexpensively obtain a constant speed control circuit of a semiconductor motor having good efficiency by allowing the voltage at one end of an armature coil to conincide with the prescribed voltage by the state of a power source voltage applied to an armature coil to drive a drive circuit. CONSTITUTION:When rotating speed decreases, the output of a tachometer generator 2 drops, the output of an OP amplifier 3 positively rises, the output of an OP amplifier 11 negatively drops, the output of a Hall element 14 increases, and the energizing current of an armature coil 34 increases. Accordingly, the decreases in the rotating speed is suppressed. When the rotating speed increases, the increase in the rotating speed is suppressed in the control reverse to the above operation, thereby maintaining constant speed. When the minimum value of the voltage at one end of the coil 34 becomes lower than the prescribed voltage V2, the output of the OP amplifier 36 increases, is compared by a comparator 40 with the output of a sawtooth wave generator 39, the ON period of a transistor 41 is lengthened, the voltage of a condenser 21 increases, and the voltage at one end of the coil 34 is allowed to be coincident to the prescribed voltage V2. When the minimum value increases as compared with the prescribed voltage V2, it is coincident to the prescribed voltage V2 under the control reverse to the above operation.

Abstract: PURPOSE:To obtain a wide-band phase modulator of simple structure by connecting one of two-branched balanced lines upside down at the multiplexing point of the lines, and then connecting diodes to those branch lines in the opposite directions. CONSTITUTION:An input signal from a microstrip line M1 is branched in phase to branch lines S1 and S2, and applied to diodes D1 and D2 provided at a distance of about lambda/2 from the branch point. When a positive voltage is applied to a bias terminal B, the diode D1 turns on and the diode D2 turns off to allow the input signal to propagate to a microstrip line M2 through the branch line S1. On the other hand, when a negative voltage is applied to a bias terminal B, the diode D1 turns off and the diode D2 turns on to send the input signal to the branch line S2. This branch line S2 is connected to an earth plate G through the diode D2, and the branch line G2 on the earth side is connected to the microstrip line M2, so the phase of the output signal is inverted.
