Title: Image forming device
Inventor: SUGINO OSAMU
IPC: G03G15/00
Filed: 1986-06-23
Abstract: PURPOSE:To prevent the generation of an image flow, even in case a corona product has adhered onto the surface of an image carrying body, setting a set value of a temperature control means so as to be higher than usual at least for a prescribed time after a power source is turned on. CONSTITUTION:When an electric conduction detecting circuit 11 detects, for instance, OFF of an electric conduction at night, and thereafter, detects turn-on of a main switch, said circuit outputs a detecting signal to a controlling circuit 12. In such a case, the controlling circuit 12 measures humidity of the use environment by a temperature sensor 10, compares it with a reference value which is determined in advance and controls the supply power to a preheater 9. That is to say, at the time of high humidity, the supply power is made to ascend and raised quickly to a temperature control temperature, and in the course of a preliminary rotation of a photosensitive drum 1, its temperature is kept long, by which a corona product which is adhered to the surface of the photosensitive drum 1 is discharged, and generation of an image flow is suppressed. In such a case, the supply power to the preheater 9 is high, therefore, even if continuous copying is executed, a temperature of the photosensitive drum 1 does not fall, and in this respect, as well, generation of the image flow can be suppressed exactly.

Title: Control apparatus for cooling fuel used in vehicle
Inventor: WATANABE SHIYUUSUKE
IPC: F02M37/08
Filed: 1982-08-26
Abstract: PURPOSE:To prevent occurrence of vapor-lock, by driving a fuel pump driving motor intermittently for a prescribed while when the fuel temperature is raised at the time when an engine is not in operation. CONSTITUTION:When the fuel temperature (t) is raised along a characteristic curve A after the time (m0) when operation of an engine is stopped and reaches a set temperature (te), a timer circuit T is set into operation at a time (m1) and a transistor Tr1 is energized. Resultantly, an intermittent driving circuit IN is set into operation and a transistor Tr2 is energized intermittently, which causes intermittent opening and closing of a contact (a2) of a relay RL2, so that a fuel pump driving motor M is operated intermittently. Thus, since the fuel temperature is lowered rapidly as shown by a characteristic curve B, it is enabled to prevent occurrence of vapor-lock.

Title: Exposure device of copying machine
Inventor: MIYAMOTO JUNZO
IPC: G03G15/043
Filed: 1984-07-17
Abstract: PURPOSE:To keep always the illuminance distribution of a projected image on a photosensitive surface uniform by peeling properly parts of a coating layer corresponding to respective corner parts of a platen to increase the light going from corner parts of the platen toward the photosensitive surface. CONSTITUTION:Both faces of a platen 3 are coated with reflection preventing films 8, and the front face is coated with a transparent conductive film 9 furthermore to form a coating layer, and parts of this coating layer corresponding to corner parts C of the platen 3 are peeled. Thus, the quantity of light irradiated from corner parts C of the platen 3 to the photosensitive surface is hardly smaller than that irradiated to corner parts C. Since the quantity of light reaching parts other than corner parts C is reduced uniformly by the reduction of the transmittance due to the coating layer, the quantity of light irradiated to the photosensitive surface from parts other than corner parts C of the platen 3 is slightly smaller than the quantity of light irradiated to these parts. As the result, the quantity of light irradiated from corner parts C of the platen 3 and that from other parts are approximately equal to each other relatively, and a lack of illuminance on parts of the photosensitive surface corresponding to corner parts C is eliminated, and the copy quality is kept well.
