Title: Image forming device
Inventor: MOGI SHIN
IPC: H04N1/04
Filed: 1992-07-30
Abstract: PURPOSE:To extend the life of a laser by providing reduced laser beam power when not in an effective scanning period which starts a predetermined period of time after a synchronism detection period has ended. CONSTITUTION:A CPU starts measuring the elapsed time and stops driving of a differential amplifier PT in response to a signal input thereto, and temporarily turns off laser radiation by means of the differential amplifier PT according to data transmitted thereto from a data portion via a D/A converter 2. After a period of time tF elapses after a BD sensor has conducted, the differential amplifier PT causes modulated laser radiation via the data portion and a gate for a period of time t0 from that point. After the period of time t0 elapses and a period of time TR elapses after the differential amplifier PT has stopped the laser radiation, the differential amplifier PT restarts laser radiation for a period of time T1, in which case the current value is designated by the CPU as one corresponding to about 1/2 or less of specific laser power.

IPC: H02H7/22
Filed: 1990-08-01
Abstract: PURPOSE:To obtain a double bus protective relay unit, in which a sound bus is not disconnected upon occurrence of a ground fault, by an arrangement wherein a current data inputted to the double bus protective relay unit is substituted substantially with zero when a bus-tie circuit breaker is in an interrupted state. CONSTITUTION:Current data I11, I21 measured through instrument current transformers 11, 21 and data S3 discriminating between open and close of a bus-tie circuit breaker 3 are inputted to a current value substituting section 95. Zero data of S3 represents open state of the bus-tie circuit breaker 3 in which switches 98, 99 are turned OFF, and the current data I11 can not be inputted to protective relay operating section 96 for bus B. Consequently, even if a ground fault F occurs on the bus interconnecting the bus-tie circuit breaker 3 and the instrument current transformer 11 and the current is measured through the instrument current transformer 11, the ground fault current has no influence on the protective relay operating section 96 for bus B and thereby the sound bus, i.e., bus B, is not disconnected from the system.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need of copying data except the map at every scroll at the time of map scrolling while basically adopting a method copying the map data and data except the map and constituting a display picture. SOLUTION: In the case of scroll start, the mask data are formed based on data except the map (b). Concretely, the mask data are the binary data where the part where data except the map exist is made '1', and the part where data except the map don't exist is made '0'. Then referring to the mask data, only the map data correspondent to the part of '0' in the mask data are copied in a display image generating storage area (c). Although the copying is performed by superscribing the data, since the map data correspondent to the part of '1' in the mask data aren't copied, the matter that the map data are copied on the part where data except the map exist is eliminated.
