Title: Halftone image output device
Inventor: ISHIKAWA HIROSHI
IPC: B41J2/44
Filed: 1987-02-05
Abstract: PURPOSE:To prevent position shift of an exposure beam even if the speed of an image forming body is irregular by detecting the irregularity in the speed of said body and moving a write device based on a signal generated in said detection. CONSTITUTION:A rotation speed detector 11 detects the rotation speed of the photosensitive body 7, transmitting an obtained frequency signal to an arithmetic operation part 20 to rotate a motor 22 so that a light emitting unit 24 is carried in parallel moving. At the time when the unit 24 in a position A, a laser beam is scanning just the position of (a) on the photosensitive body 7, however, if the unit 24 is moved to a position B, the laser beam moves on the body 7 for the same length as that the unit 24 moves and scans a position (b). The length of said moving is determined from an irregular-speed frequency at which a streak tends to appear and its magnitude. In such a way, the positional shift of an exposure beam even if the speed of an image forming body is irregular, and the occurrence of a periodic streaks on a halftone image can be prevented.

IPC: G03C1/08
Filed: 1989-02-03
Abstract: PURPOSE:To obtain high image quality and to lessen the increase of fogging by lapse of a long period of time and the deterioration of photographic performance, etc., by the degradation of graininess, etc., by specifying the total ratio of the potassium ions to be incorporated into the photosensitive material. CONSTITUTION:The total ratio of the potassium ions to be incorporated into the photosensitive material which is the silver halide photographic sensitive material contg. photosensitive silver halide emulsion layers on a base is specified to <=1X10<-3> by the total weight of silver. The increase of fogging by the lapse of time and the deterioration of the graininess arise drastically when the total ratio, by weight, of the potassium ions incorporated into the photosensitive material exceeds 1X10<-3> by the total weight of the silver. The total ratio of the potassium ions to be incorporated into the photosensitive material is preferably <=5X10<-4>, more particularly preferably <=3X10<-4> by the total weight of silver. The increase of the fogging and the degradation of the graininess when the photosensitive material is rested for a long period of time after production are lessened in this way.

Title: Wiring method of wiring passing over functional block
Inventor: GOI SATOSHI
IPC: H01L23/52
Filed: 1989-02-03
Abstract: PURPOSE:To reduce wasteful wiring regions by determining the direction of the passage of a wiring over a functional block according to the state of the periphery of the functional block. CONSTITUTION:More wirings 41 are passed over a functional block 20, and fewer wirings 42 bypass the functional block 20. Wirings (wirings to be passed on shortest-distance wirings) to be passed through the functional block 20 are picked up for that, the number of wirings passed in the lateral direction and wiring passed in the longitudinal direction in these wirings is acquired and compared, and the direction of more wirings may be determined in the direction of wirings on the functional block. That is, since there are five longitudinal wirings 41 and two lateral wirings 42, longitudinal wirings are made more than lateral wirings, thus deciding the direction of wirings passed on the functional block as the longitudinal direction, then passing the longitudinal wirings 41 on the functional block, provided that the lateral wirings 42 bypass the functional block. Accordingly, wasteful wiring regions are decreased, thus reducing the area of a chip.

An objective lens 35 is then moved so as to negative a focus error signal even if the distance between a recording medium 18 and the lens 35 does not change. The distance between the recording medium and the lens 35 is thus changed. The spot size by the lens 35 has the specified and min. value within the focal depth of the lens 35 and therefore the spot size is taken larger as compared to the size in the stage of a recording mode by moving the lens 35 beyond the focal depth of the lens 35.

Title: Dew condensation preventing heater of copying machine
Inventor: ARAI HARUO
IPC: H05B3/00
Filed: 1984-02-14
Abstract: PURPOSE:To prevent dew condensation under two-stage temperature control which does not require strictly the precision and also to prevent unnecessary power consumption by using a half-wave rectifier when the temperature in a machine rises by using two temperature switches. CONSTITUTION:The on temperature of the 1st and the 2nd thermostats 7 and 8 are set to about 5 deg.C and the dew condensation preventing heater 3 is powered on below said temperature. At this time, the 2nd thermostat 8 short-circuits the half-wave rectifier 9 and flows a full-wave AC current to the heater 3, which generates heat. Even when the room temperature rises after the start of room heating, the heater 3 is put in operation, so no dew is condensed. When the temperature in the machine rises up to 15 deg.C owing to the rise in the room temperature, the 2nd thermostat 8 turns off and the current flowing through the heater 3 passes through the 1st thermostat 7 and half-wave rectifier 9 to reduce the heating value of the heater 3 to about half. When the temperature in the machine attains to about 20 deg.C, the 1st temperature switch 7 is also turned off and no current flows to the heater 3, so that no heat is generated.
