Patent JP-S61156908-A (JP)
Title: Isolation amplifier
Inventor: YAMAMURO KIYOSHI
IPC: H03F3/20
Filed: 1984-12-28
Abstract: PURPOSE:To improve the linearity and temperature characteristic of the output by making a delay in on-off of an output of a photocoupler very small and decreasing a residual voltage of a comparator in a demodulation circuit. CONSTITUTION:An output from a pulse width modulation circuit 1 having the duty ratio proportional to an input voltage Vin turns on/off a light emitting diode of the photocoupler 2. The emitter E and the collector C of a phototransistor at the secondary side are turned on/off by the turning on/off above and when the transistor is turned on, a potential VC- of comparators Q31, Q32 is higher than a potential VC+ by the barrier voltage of a diode D32 and the output of the comparators Q31, Q32 goes to LOW. A residual voltage VCO31 is generated at the output of the comparator Q31 relative to a current flowing from a power supply voltage E3. The residual voltage VCO31 is smaller as the flowing current is decreased. The delay in the on/off of the photocoupler is made very small in this way and the residual voltage of the comparator is decreased, allowing to improve the linearity and temperature characteristic of the output.

Title: Frequency characteristic compensation circuit
Inventor: SUZUKI TAKAO
IPC: H03H11/18
Filed: 1985-12-06
Abstract: PURPOSE:To attain the flat phase characteristic and to preclude the possibility of phase distortion by inserting and connecting a transversal filter to the output side of a D/A converter or the input side of an A/D converter. CONSTITUTION:A sampling peak digital signal from an input terminal 1 is converted into an analog signal having the 0-th order hold by a D/A converter 2 and the result is given to a cosine equalizer 3 for compensating a (sinx)/x characteristic. The cosine equalizer 3 utilizes the total reflection at a connection end with a differential amplifier 8 being a nearly open end of a delay line 6 and the one delay line 6 constitutes a three-tap transversal filter. In order to compensate the (sinx)/x characteristic of the D/A converter 2, the compensation close to the ideal is attained, a flat phase characteristic is obtained and phase distortion is eliminated without the high-order compensation as with a filter using L, C, R by employing the cosine equalizer 3 using the delay line 6.

IPC: H04J3/00
Filed: 1984-12-28
Abstract: PURPOSE:To attain data changing transfer between die groups by providing a memory capable of rewriting a data, an address generating section outputting a memory address, a write control section applying write control to a data into a memory and a selector controlling switchingly plural said synchronous serial data in response to the data read out of the memory. CONSTITUTION:A control data decoded by a changing transfer selector control converting section 2 at the transmission side and transmitting a changeover data to apply switch control to a changing transfer selector 1 at the transmission side are described in a memory section 3. Since the memory section 3 is accessed by an address in, e.g., 5-bit, 32 ways of control data are stored. Thus, a prescribed changing transfer control is attained by writing properly a data of the memory section 3 to a write control section 12 based on which state the changing transfer control is applied. The entirely converse operation has only to be executed in case of the reception. Thus, changing transfer of plural synchronous serial data at each word is attained by writing a data to the memory without special hardware change.
