IPC: H04W88/02
Filed: 1988-06-24
Abstract: PURPOSE:To reduce the current consumption of the title receiver so that the battery of the receiver can be extended in service life by operating the receiver with high-speed clocks only when it is detected that the receiver itself is called during the receiving period of the group to which the receiver itself belongs, with the receiver being operated with low-speed clocks while the receiver itself is not called. CONSTITUTION:A control circuit 40 outputs ON/OFF control signals to a battery saving circuit 10 after acquisition of synchronism is completed to set a radio circuit 2 and demodulator circuit 3 to reception operating states during the receiving period of its own group 2 only. The control circuit 40 leads in and uses low-speed clocks generated from the 2nd clock oscillator 29 as operating clocks through the full period of one frame unless a call to its own receiver is detected. Upon detecting a call to its own receiver as a result of collation to individual number coding, the circuit 40 switches the operating clocks from the low-speed clocks to high-speed clocks generated by a 1st clock oscillator 91. Thereafter, message codes are decoded synchronously to the high-speed clocks and, upon completing the decoding, the operating clocks are returned to the low-speed clocks.

Title: Optical logical circuit
Inventor: INOUE NAOHISA
IPC: H03K19/14
Filed: 1984-07-26
Abstract: PURPOSE:To cause a transfer of optical power between two optical waveguides and to control a transfer of light with impressed voltage when the voltage is impressed to an electrode and the phase constant is made equal due to the variation of refractive index at the part where the voltage is impressed, by making the phase constant of mutually adjacent part of two optical waveguides differ. CONSTITUTION:When the logical values of an input optical signal IinA and IinB are both 0, and output optical signal Iout is also 0. Also when the logical value of the optical signal IinA is 1 and that of the optical signal IinB is 0, the output signal Iout is 0. In case when IinA is 0 and IinB is 1, no electromotive force occurs at a light electromotive element 31. When both of input optical signal IinA and IinB are 1, a voltage is evoked at the light electromotive element 31 by the light travelling through a waveguide 11, and impressed to an electrode 21. Therefore, the light travelling through an optical waiveguide 13 is transferred by a directional coupler to an optical waveguide 14 resulting in output optical signal Iout being 1.
