Abstract: PURPOSE:To record correct data signal in a column by realizing transmission of an extremely wide band from a DC to a high frequency. CONSTITUTION:A data channel 4 of a rotary transformer transmits a data signal to a secondary side core of a rotor side. A slicer 7 converts the signal to a binary signal according to whether the signal exceeds a predetermined level or not. A quantized feedback circuit 8 quantizes the binary signal from the slicer 7.

Filed: 1987-12-22
Abstract: PURPOSE:To enhance response, by connecting a response improving circuit and a condenser of predetermined capacity to the gate input of an MOS input type differential amplifying means for inputting the photocurrent generated from a photodiode. CONSTITUTION:Immediately after a power supply is closed, a charge current is allowed to flow to the MOS capacity of a differential amplifier A connected to a spot photodiode 2 for a certain definite time through the line l2 of a response improving circuit RES. After a predetermined time, photometry by the photodiode is performed. Next, when the level of a change-over signal S/A is changed over, a charge current is allowed to flow to the MOS capacity connected to an average photodiode 1 for a certain definite time through the line l1 of the circuit RES. After a predetermined time, photometry is performed by the photodiode 1. In average photometry, according to circumstances, an output signal V0 does not reach a steady level at a photometry time. Thereupon, a condenser C of predetermined capacity is connected to the gate input terminal on the side of the photodiode 1 and, when the capacity thereof is increased, ringing is relaxes and the time reaching a steady level can be shortened and response is enhanced.
