Title: Counter fault detecting circuit
Inventor: OKADA KOUICHIROU
IPC: H03K21/40
Filed: 1991-04-18
Abstract: PURPOSE:To obtain a circuit which detects the fault of a counter without duplexing the counter. CONSTITUTION:The counted value 2 is outputted from a 4-bit counter 1 and then inputted to a horizontal parity generating circuit 3. The circuit 3 generates the horizontal parity value based on the value 2. Then horizontal parity value is outputted from the circuit 3 and inputted to a fault detecting circuit 4. Then the circuit 4 turns two continuous horizontal parity values into a pair and secures the exclusive OR of both values to generate the checked value. The fault of the counter 1 is decided when the checked value is equal to '0', and a fault detection signal 6 is transmitted from the circuit 4. In regard of the checking timing, a detection timing control circuit 5 instructs a check every two counting operations of the counter 1.

Title: Semiconductor photodetector
Inventor: ISHIHARA HISAHIRO
IPC: H01L31/10
Filed: 1990-05-22
Abstract: PURPOSE:To obtain a high quantum efficiency characteristic securely without spoiling the high-speed response characteristic, by providing a semiconductor region having a band gap smaller than a photoabsorption layer between a buffer layer and a board region excluding the part under light-receiving region, at a Pin-PD where multi-layer semiconductor films are laminated. CONSTITUTION:After an n-InGaAs 2 is crystal-grown on a semi-insulating InP substrate 1, the n-InGaAs 2 of a circular region is removed by selective etching. After that (n<+>-InP 3/n-InP 4) buffer layers, an n<->-InGaAs photoabsorption layer 5, and an n-InP window layer 6 are lattice-matched and grown consecutively. After that circular p-n junction is formed in the InGaAs layer 5 by selective thermal diffusion. Hereupon this p<+> diffusion region is overlapped with the selectively etched region, and this circular region makes a light-receiving region. Next a p-side electrode 9 and an n-side electrode 10 are formed on the substrate 1. Lastly, a multi-layer reflecting film consisting of an insulating film 11 and a reflecting matal 12 is formed on the rear. As a transmitted light component, unabsorbed one of incident signal light, is reflected on the rear of the board and strikes the photoabsorption layer again, the practical thickness of the photoabsorption layer increases and quantum efficiency can be increased.

Title: Still picture television telephone set
Inventor: KURIBAYASHI AKIRA
IPC: H04N7/14
Filed: 1991-05-09
Abstract: PURPOSE:To implement transmission reception simultaneously and to improve the transmission efficiency by adding transmission signals whose phase are inverted with a signal addition function so as to cancel the transmission signal thereby demodulating only a reception data. CONSTITUTION:An NCU section 3 disconnects a telephone set from a telephone line on the reception of a picture signal to connect a signal addition section 9 to a telephone line 6. When no picture signal is sent, a reception signal is demodulated by a demodulation section 4 and converted into a picture data via an A/D converter section 5 and the data is received. In the case of sending the picture data, the section 3 connects a modulation section 2 to the line 6, the section 2 modulates the picture data and the result is sent to the line 6. When the picture data is sent from an opposite party during the transmission, the transmission signal and the reception signal are synthesized on the line 6 and the synthesis signal is inputted to the section 9. In this case, since the transmission signal whose phase is inverted by a phase inversion section 8 is synthesized by the section 9, the section 4 cancels the transmission signal and only the reception signal is demodulated, Then the normal reception signal is received via the section 5.

Title: Device for preventing springback of wire in drum type wire drawing machine
Inventor: KISHI SEIKI
IPC: B21C1/02
Filed: 1995-05-08
Abstract: PURPOSE: To secure safety of an operator and to improve workability by covering with a material for producing a friction force sufficiently for preventing springback at the time of contact with a wire. CONSTITUTION: With an end of a wire 1 fixed on a drum 4, the drawing of the wire is performed by a rotational force of the drum 4. Since the rotating of the drum 4 stops when the tail end 7 of the wire 1 is passed through a die 3, a cylindrical roll 5 is pushed to a position 8 close to the wire 1 so that the tail end 7 of the wire may not be turned free. As a result, springback coming loose in the axial direction of the wire 1 is stopped by the cylindrical roll 5. With the rotation of the drum 4 stopping, springback also appears in the tail end 7 returning in the axial direction of the wire 1 as indicated by the arrow C. This is prevented by restraining the wire 1 by a friction force between the wire 1 and the cylindrical roll 5. The surface of the cylindrical roll 5 is 'SOLIDUR(R)' covered 11. Consequently, springback of the wire is prevented without causing scratches on it.
