Title: Supervisory system for unlicensed mobile station
Inventor: KANO EIICHI
IPC: H04B17/345
Filed: 1995-03-15
Abstract: PURPOSE: To specify a mobile station radiating unlicensed radio wave automatically. CONSTITUTION: An antenna 16 having steep directivity receives radio wave radiated from a mobile station 12 and a controller 14 extracts each frequency component from the output signal of the antenna 16. The controller 14 compares the level of each frequency component thus extracted with a predetermined allowable level and delivers a trigger signal when the level of each frequency component deviates from the allowable level. A camera 18 photographs the mobile station 12 in response to the trigger signal. Since the mobile station 12 radiating unlicensed radio wave is photographed, the mobile station 12 can be identified from the number plate of automobile.

Title: Control circuit of oscillation voltage
Inventor: TSUCHIYA SHIGEO
IPC: H03L5/00
Filed: 1983-05-13
Abstract: PURPOSE:To suppress the undesired spurious component and at the same time to control the oscillation voltage at a fixed level with oscillation frequencies of a wide range so that the stable working of a control circuit for oscillation voltage despite the reduction of voltage, by detecting the oscillation voltage and varying the power supply voltage to be supplied to an oscillating circuit by the detection output of said oscillation voltage. CONSTITUTION:No output is delivered from an oscillating circuit at an oscillation starting time point when a power supply VCC is applied. Therefore no detection output is delivered from an oscillation voltage detecting circuit 13 via a buffer amplifier 12. A field effect transistor TRQ3 of an oscillation voltage control circuit 14 supplies a current IDSS obtained when the start current is increased to a TRQ1 of the circuit 11. As a result, the circuit 11 starts its oscillation with oscillation frequencies of prescribed crystal oscillators X1-Xn selected by a switch S. Thus the detection output of the circuit 13 is supplied to the TRQ3 of the circuit 14 via the amplifier 12. Therefore the oscillation voltage of the circuit 11 is controlled to be set at a certain fixed level lower than the level set immediately after the start of oscillation.
