Title: Checking method for defect of optical disk
Inventor: ARAI SHIGERU
IPC: G01N21/88
Filed: 1983-04-18
Abstract: PURPOSE:To check a minute projecting/recessing-form defect of an optical disk by irradiating a laser beam to the optical disk to detect the reflected light sent from the optical disk by four divided optical detectors set at the far field positions within an optical head and comparing the sum and difference signals with a reference value respectively. CONSTITUTION:The laser beam delivered from a semiconductor laser 32 is reflected by 90 deg. by a polarized beam splitter 34 via a collimator lens 33 and focused by an objective lens 36 with the polarized surface turned by a 1/4 wavelength plate 35 and then irradiated on an optical disk 1. For the reflected laser beam, the polarized surface is further turned by the plate 35 through the lens 36. Then the reflected beam is detected by an optical detector 31 after passing through the splitter 34. This detector 31 contains four divided photodetecting elements. An adder 4 calculates the sum signal, the difference signal of the disk radius direction and the difference signal of the disk circumference direction. These signals are compared with each reference value through a defect detecting circuit 5, and the signals exceeding the reference value are counted and stored temporarily in a data buffer 6. Then the data processing is carried out by a calculating device 7. In such a way, a defect can be detected for a minute projection/ recessing of an optical disk.

Title: Fault location retrieval system in optical relay transmission system
Inventor: TANAKA SHIGEKI
IPC: H04B17/40
Filed: 1985-03-29
Abstract: PURPOSE:To retrieve a faulty location even when any terminal station by applying loopback automatically to a repeater of a faulty location and allocating a specific delay to each repeater when a transmission line is faulty. CONSTITUTION:A violent code detector 71a of a repeater 4 detects a violent code due to a fault at a point P to drive a changeover circuit 72 for loopback. As a result, since an input signal of an outgoing transmission line 6b of a repeater 3 does not satisfy a code mark inversion (CMT) code rule, the repeater 3 applies automatically loopback. When loopback is applied in a transmission line at a fault, a reference loopback pulse pattern for measure measurement inputted to a CMI coding circuit of a terminal station 1 is sent to a transmission line 6 by a signal sending circuit as the CMI code and subject to loopback by a delay amount. Then the signal is received by the signal reception circuit of the same terminal station 1 as the transmission and the CMI coding circuit outputs the original measuring pulse pattern. In this case, the time difference between the reference pulse pattern and the reception pulse pattern is read to decide a faulty location.

Title: Safety device for hot air heater
Inventor: YAMAGUCHI HIROSHI
IPC: F24H3/04
Filed: 1989-03-22
Abstract: PURPOSE:To prevent the generation of accidents by installing a microcomputer, to which a detection signal of a flame sensor is inputted by way of a first input terminal and which shutdowns a fuel system during emergency, and a second input terminal which has a high impedance grounding resistance and forms a leak electric current for the microcomputer. CONSTITUTION:When voltage is applied to a flame sensor 2, ion electric current flows through a resistor 4 and then a potential difference is produced between an input terminal 5 of a microcomputer 1 and its earth. When the combustion of a burner 3 is subject to an abnormal state, the potential difference of the terminal 5 is reduced so that the abnormal state may be identified and an output signal 8 shutdowns a solenoid valve for a fuel supply passage by way of a relay 10. Even when the temperature of a heater rises above a specified temperature by emergency combustion and leak current is produced inside the microcomptuer 1, the electric current is divided into A and B and flows to the earth side, if a leak current is produced in the microcomputer 1. No fluctuation can be observed in the value of electric current flowing through an earth resistor 7a, depending on the magnitude of the leak current. However, the leak current B flows into the earth by way of a resistor 22, a high impedance resistor 7, producing a potential difference between the input terminal 6 and the earth. The microcomputer 1, when this potential difference is detected, halts the operation.
