Title: Photometric circuit
Inventor: ARIMA JIRO
IPC: G01J1/44
Filed: 1987-07-07
Abstract: PURPOSE:To obtain a photometric circuit simple in constitution with good light measurement accuracy by photodetecting stationary light and chopped light by using only one sensor. CONSTITUTION:A resistance 13 which converts a photocurrent into a voltage is connected in series with the sensor 3 and a capacitor 15 which leads only an AC component out is connected to the connection point to pass a high frequency signal and cut a low frequency signal. The output of the AC component is amplified by an amplifier 16, whose output is supplied to a circuit 8 which generates a timing signal for sample holding from the signal of the AC component and an absolute value circuit 9. Further, the photoelectric current of the sensor 3 is amplified by an amplifier 14, whose output is sent to a sample holding circuit 7 for extracting the signal of the DC component. Consequently, the signals of the DC and AC components are amplified only by the amplifiers 14 and 16 to improve the S/N. The variations of the signals of the DC and AC components are about 10<3> times and >=100 times, but this circuit uses the amplifiers 14 and 16 individually, so proper magnification can be applied.

Title: Pulse generator
Inventor: IO SHINICHI
IPC: H03K17/968
Filed: 1984-08-15
Abstract: PURPOSE:To prevent malfunction due to displacement of a shut device caused by vibration or the like by providing a control circuit increasing the light emitting amount when an optical signal received intermittently from a light emitting element via the shut device reaches the operating level of a photodetector. CONSTITUTION:A slit disc 1 is fitted to a rotary shaft 2 turned proportional to a wheel, a slit 3 having a prescribed width is formed to the peripheral at an equal interval, and alight emitting diode D1 and a photo transistor (Tr)1 are arranged while clipping the slip 3. As the disc 1 is turned, a pulse current i2 flows through resistors R2, R3 to the Tr1 by using an optical signal from the D1 intermitted by the slit 3. When the level by the current i2 reaches the operating setting level of a Tr2, a current i3 flows to the Tr2 and the level of an output terminal OUT goes to a low potential. Then the diode D2 of a light emitting amount control circuit 5 is conducted by it, a current i4 flows thereto and a current (i1+i4) flows to the D1 to increase the light emitting quantity. Thus, the conductive period of the Tr2 is prolonged and made stable, the effect of the deviation of the slit 3 due to minute vibration of the shaft 2 is less and malfunction is prevented.

Title: Parallel feedback type analog-digital converter
Inventor: SHIMIZU SHIYOUICHI
IPC: H03M1/36
Filed: 1979-12-27
Abstract: PURPOSE:To improve the differentiation linearity, by eliminating the offset effect of a D/A converter. CONSTITUTION:For the switching comparators 3-5, the unit comparators 3a-5a of the upper side operate first to perform a comparison between the input analog  voltage and the 1st reference voltage, and the higher-rank bit group is obtained  through the encoding circuit 28 for the A/D conversion output. The digital codes of  the higher-rank bit group are stored in the registers 29 and 30. The output of the register 29 is converted into the analog voltage through the D/A converter 31 to be fed back as the reference voltage to obtain the lower-rank bit group. The auxiliary comparators 24-27 are provided in addition to the main comparators 3-5. Thus the value of the lower-rank bit group is set up by the comparison results of the auxiliary comparators in case the input analog voltage gets out of the range of comparison of the main comparators when the 2nd reference voltage becomes out of the normal value due to the offset of the D/A converter and other factors. At the same time, the value is compensated also for the higher-rank bit group.

IPC: H04J1/00
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To prevent easy suffering of the disturbance to communication without complicating the constitution and to increase the range of communication by converting the modulated signals or secondary modulating signals via an impulse string signal in terms of frequency to scatter the converted signals as plural frequency signals for radio communication, integrating the frequency signals via an envelope detection circuit in terms of time at the receiving side to perform synthesizing of signals and relatively improving the S/N ratio.

Meanwhile, the BPF 1 and BPF 2 of the receiver side have the characteristics of the central frequency and the pass-band width which are equal to those of the BPF 1 and BPF 2 of the transmitter side. Two envelope detection circuits perform the envelope detection of outputs of the BPF 1 and BPF 2 respectively. Each of both envelope circuits has a circuit which rectifies the input signals, a filter circuit which filters the rectified signals with a prescribed time constant via a capacitor, etc., and a circuit which discharges the charged electric charge of the capacitor.

Title: Encoding system
Inventor: KAMEDA HIROMI
IPC: H03M13/00
Filed: 1983-09-18
Abstract: PURPOSE:To reduce an error generation rate and to ensure speedy and secure random access by adding error detecting codes (CRC) for exclusive-use of address data and constituting address data and a CRC subblock. CONSTITUTION:A CRC for exclusive-use of address data is added to an encoding format so as to have such bit constitution as shown in the figure. As a result, one conventional block becomes 168 bits in all and one block in this invention becomes 184 bits. An address data error detecting test at the time of random access is implemented by 160 bits in the conventional system. The present system tests errors by address data and the CRC (subblock) for address, and the number of bits is 32. Consequently, a bit error rate of reproduced data at the time of random access decreases to one-fifth compared with the conventional system. Through the separation of said CRC code, CRC codes for address and for data are imputted into CRC check circuit for address 5 and CRC check circuit for PCM data 6, respectively. If the circuit 5 detects no error, a computer 8 random-accesses. If there are errors, the computer informs storage media of invalidity of data.

Abstract: PURPOSE:To obtain the titled device which is suppressed a bad influence on lattice unconformity by laminating a distorted super lattice layer composed of >=2 kinds of II-VI compd. semiconductor on an insulating film formed on a principal surface of the semiconductor substrate or an insulating film substrate. CONSTITUTION:The titled device is composed of for example, the Si substrate 1, the SiO2 thermal oxidation film 2, the optical wave guide layer composed of ZnS0.5Se0.5 monocrystal thin film 3, the distorted super lattice layer 4, 4' composed of ZnS and ZnS0.5Se0.5, and the clad layer for optical confinement composed of ZnS monocrystal thin film 5. The good epitaxial glowth film is formed by epitaxially growing the II-VI compd. semiconductor on the SiO2 substrate interposing the distorted super lattice layer as a buffer layer between them, thereby mitigating disparity of the crystal structure and the grating constant. And, the SiO2 film is sufficiently useful for the clad layer having a difference of the refractive index. Thus, the generation of defects such as a misfit arrangement, etc., due to the lattice unconformity and the lowering of crystallization are prevented.
