IPC: H04Q7/36
Filed: 1984-02-29
Abstract: PURPOSE:To prevent surely mis-calling between zones by transmitting a signal added with a scramble code in an optional bit of a selective call signal with prescribed logical operation from a base station to allow a receiver to operate inversely the scramble code. CONSTITUTION:The selective call number and message information from a subscriber telephone set are received by a base station of the selective call system, and the coder codes the call number and the message into an information bit (16-bit) comprising an individual number code (11-bit) and a message (5-bit). A check bit in 15-bit is added to the information bit 16, a scramble code (A) in 4-bit is added to the end while exclusive OR operation is applied and the result is transmitted. Then the receiver provided with an inverse logical operation circuit 10, a scramble code operation circuit 11, a ROM5, an error correction operating circuit 3 and a collation circuit 4 operates inversely the transmitted scramble code to prevent mis-calling between zones.

Filed: 1988-02-22
Abstract: PURPOSE:To improve the accuracy of the rotation detection of an optical rotation detector by dividing the optical beam projected on an encoder into three parts by means of a grating plate and using the central beam for focusing and beams on both sides for obtaining rotation detect signals. CONSTITUTION:An optical beam is projected from a pickup 31 on an optical encoder constituted in a laminated state of a reflecting member provided with plural pits arranged at regular angles in the circumferential direction, protecting member, and transparent member. The optical beam is divided into three parts by means of a grating plate (diffraction grating plate) and projected on the encoder as three beams. Of the three reflecting beams from the encoder, the central one is led to 4 photodetectors Da-Dd arranged in the form of a square and electric signals A-D to be used for focus control are obtained. The reflecting beams on both sides are led to photodetectors De and Df and become electric signals E and F for obtaining rotation detect signals. The signals E and F are supplied to an encoder signal processing section 33 and becomes A- and B-phase signals having a phase difference of pi/2 radian in electric angle between them.

IPC: H01H3/24
Filed: 1990-02-21
Abstract: PURPOSE:To equalize operating times of a pressure oil pump for a long period by operating a solenoid valve connecting a high and a low pressure side of an oil pressure system to each other at every predetermined interval so as to forcibly operate the pressure oil pump. CONSTITUTION:Upon operation of a pressure oil pump 1, a pressure is increased. A pressure switch 17a is turned off, and an electromagnetic contactor 22 is deenergized. A contact 22a is turned off, and a contact 22c is turned on simultaneously with a stoppage of the pump 1, thus energizing a timer relay 27. After an elapse of a predetermined time, a contact 27a is turned on to energize an electromagnetic contactor 29. A contact 29a excites a solenoid valve 30 to operate. As a result, high pressure oil is released from a high pressure side to a low pressure side via the valve 30. With a decrease in high pressure oil pressure, the switch 17a is turned on to energize the contactor 22, thus operating the pump 1. In addition, upon detection of the operation of the contact 22a of the contactor 22, the relay 27 is driven to operate the solenoid valve between high and low pressure so that operating times of the solenoid valve can be reduced with respect to an increase in interior leak.
