Title: Automatic adjusting device for filter
Inventor: NAKANO KOICHI
IPC: H03H11/04
Filed: 1989-12-01
Abstract: PURPOSE:To suppress the fluctuation of the cut-off frequency of a filter even when a resistance or a capacitance is fluctuated by comparing the phase of an output signal of a reference filter with the phase of an inputted reference signal land generating a control signal in response to the difference. CONSTITUTION:A phase comparator 19 consists of a limiter 13, a multiplier 14 and an integration device 15 and the phase difference between a reference signal generated from a reference signal oscillation circuit 11 and an output signal from a reference filter 12 is compared. When the cut-off frequency of the filter 12 is correct, since the phase difference is a set value, no control signal is generated from the comparator 19. When the cut-off frequency of the filter 12 is fluctuated due to temperature fluctuation or the like and the cut-off frequency of a filter 16 to be adjusted is fluctuated, since the phase difference between the output signal of the filter 12 and the reference signal is not a set value, a control signal is generated from the comparator 19 and fed to the filters 12,16 to set the cut-off frequency of both the filters 12,16 to a set value.

Title: Transmitting device for optical radio data
Inventor: IWASAKI YOSHIKI
IPC: H04B10/60
Filed: 1988-12-12
Abstract: PURPOSE:To use a light emitting element with higher efficiency by driving intermittently the light emitting element and thereby to suppress the temperature rise of the element. CONSTITUTION:A light emitting element is turned on and off at a prescribed time interval. The input dat is written into a buffer 1 with no delay with a write clock and then read of the data out of the buffer 1 is executed with the read clock given from a CPU 2. Thus the output data sent to the CPU 2 from the buffer 1 is sent to a light emitting driver 3. The driver 3 drives a light emitting element 4 based on the received output data and transmits an optical signal. The input data, even if received continuously, are sent from the buffer 1 after the CPU pause time t2 as long as the buffer 1 has a sufficient capacity. Thus it is possible to prevent the inadvertent rise of temperature of a light emitter and to ensure a highly efficient light emitting action.

Abstract: PURPOSE:To simplify the circuit constitution by inputting the output of one current voltage conversion circuit to an A/D converter while using the output as the reference of the order. CONSTITUTION:The output of an A/D converter 11 is expressed by a ratio of an input voltage to a reference voltage; and in the case of 8-bit constitution, an output (FF)H/2 is equal to 80H when a servo error signal should be 0, and it is larger at the time of A>B, and it is smaller at the time of A<B, and the servo error signal is expanded with the center value 80H of the output as the center. Consequently, the full scale of the converter 11 is allowed to correspond to V, and the output of the converter 11 is converted and is inputted to a differential amplifier 13 having the reference value as V/2 to obtain an objective k(A-B)/(A+B). At such a time, the output VA of a current/voltage conversion circuit 14 is used as the reference of a current/voltage conversion circuit 15, and the output of the circuit 15 is assumed as the sum VA+VB of them in viwing from a reference potential V0 of the circuit 14.

Abstract: PURPOSE:To easily execute the detection by comparing and collating one kind by inverting received frame format data in accordance with necessity. CONSTITUTION:Parallel conversion data 4 in an n-bit unit from a series-parallel converting part 3 is compared and collated with an (n) bit frame synchronizing pattern 6 from a local frame generating part 5 by a timing of a comparison/ collation timing signal 10, in a comparing/collating part 7.

Abstract: PURPOSE:To suppress the reduction of the speed of a read operation with a low source voltage, to prevent data from being written or erased erroneously, and to make an operating source voltage into a low voltage by connecting the gate of an N-channel transistor to the output of a constant potential supply circuit. CONSTITUTION:The constant potential supply circuit 9 is comprised of a Pch- transistor 10 and Nch-transistors 11-13.
