Title: Electrophotographic process
Inventor: KINOU HIDEKI
IPC: G03G21/00
Filed: 1981-10-08
Abstract: PURPOSE:To stabilize electrostatic charging characteristics in an electrophotographic method using an Ai:H type material as a photoreceptor by irradiating light to the surface of the photoreceptor in the fore stage of ordinary processes. CONSTITUTION:In an electrophotographic method using an amorphous silicon (a-Si:H) type photoreceptor contg. hydrogen, the use of white light for photosensitization and destaticiation leads to a finding that while said photoreceptor has large fluctuations in electrostatic charging initially it has stable characteristics on long-term repetitive use. Thereupon, the idle operation of irradiating the photoreceptor by a light source 6 for destaticization (or a light source to be used exclusively for the same may be used) is performed prior to an actual operation, whereby the initial stability in characteristics is eliminated and the electrostatic charging is kept stable at all times.

Title: Fault location detection system for loop transmission line
Inventor: SHIMADA HAJIME
IPC: H04L12/42
Filed: 1990-06-20
Abstract: PURPOSE:To detect a fault point in a short time without making the system complicated by sending sequentially a reply request signal to each monitored station and discriminating an interrupting state of a fault signal so as to detect a position at which the fault takes place. CONSTITUTION:When a fault takes place in a transmission line 1 for data transmission, a reception circuit 3 of a monitored station S1 just after a fault location A detects it and sends a fault detection signal 11 to a control circuit 7. Upon the receipt of the fault detection signal 11, the control circuit 7 generates a fault signal 12. The fault signal 12 is sent to a transmission line 2 via a reply control circuit 6 and a changeover circuit 5 from a transmission circuit 4a. A fault signal from the reception circuit 3 passes through a reply control circuit 6 and is sent from the transmission circuit 4a to the transmission line 2 and sent to a monitor station M via a monitored station at the host side of the transmission line 1 sequentially. The fault signal is sent to a monitor control circuit 10 via a reception circuit 8a of the monitor station M and the fault is detected by the monitor control circuit 10. Thus, a fault location is detected in short time with simple constitution.

Title: Liquid crystal display device
Inventor: FUKUDA MINORU
IPC: G02F1/1335
Filed: 1988-06-29
Abstract: PURPOSE:To reduce the power consumption of a lighting means by detecting ambient illuminance and adjusting the brightness of a means which light a liquid crystal display part from behind according to the detected illuminance. CONSTITUTION:When the ambient illuminance L is high, the emitter current (i) of a photosensor 61 is large corresponding to the illuminance L and the collector-emitter voltage EA of a transistor 63 for amplification is low. As the voltage EA becomes low, the collector-emitter impedance of a transistor 71, i.e. the output impedance Z of a brightness adjustment part 7 increases and a source current to a back light 3 decreases, so the brightness B of the back light 3 decreases. Therefore, when the ambient illuminance L increases with a switch 5 on, the brightness B of the back light 3 decreases automatically. Consequently, the power consumption of the back light 3 can be reduced.
