IPC: G03G15/08
Filed: 1989-06-14
Abstract: PURPOSE:To sufficiently convey a developer to a developing area without the scattering of the developer and to eliminate the occurrence of fogging, etc., on an image by providing an electric field curtain generating means for developer conveyance and an electric field curtain generating means for development. CONSTITUTION:When the developer is supplied onto a developer carrying and conveying body 11, it is conveyed to the developing area facing an image carrier 20 by the action of an electric field curtain generated by the electric field curtain generating means 30 provided on the developer carrying and conveying body 11 for the developer conveyance. When, the developer is conveyed to the developing area facing the image carrier 20, then in this developing area, the developer is carried away by the action of an electric field curtain generated by the electric field curtain generating means 40 provided between the developer carrying and conveying body 11 and the image carrier 20 for the development, softly brought into contact with the image carrier 20 and supplied to the electrostatic latent image point of the image carrier 20.

Title: Electrostatic recorder
Inventor: YAGI KEIICHI
IPC: G03G15/00
Filed: 1990-06-12
Abstract: PURPOSE:To prevent picture quality from deteriorating even if a recording sheet of paper is stained by providing a sucking means which sucks the recording medium nearby a transfer means. CONSTITUTION:The sucking means 25 which sucks the recording medium 28 is provided nearby the transfer means 22. Therefore, even when what is called cut paper which is cut to specific size previously is used as the recording medium 28, the front and rear end parts of the recording medium 28 can be sucked by the sucking means 25 provided nearby the transfer means 22. Consequently, the recording medium 28 can be held at a specific position when the front end part and rear end part of the recording medium 28 passes the transfer part 22 and the recording medium 28 is never stained due to contact with a developer carrier 4 which carries a thin layer of a developer 2. Consequently, the print surface, etc., of the recording medium 117 is not stained and deterioration in the picture quality is eliminated.

Title: Heat pump type hot water feeder
Inventor: OKUMA KEIKO
IPC: F25B30/02
Filed: 1987-06-17
Abstract: PURPOSE:To enable a high economic operation to be performed by a method wherein the operation is controlled in such a way as an amount of remained hot water within a hot water storing tank is suppressed substantially at a constant value within a certain set time and in turn an amount of remaining hot water in the hot water storing tank is kept full within a time period of low electric power bill. CONSTITUTION:An amount of remained hot water is detected by a hot water temperature sensor 22 within a set time for setting an amount of remained hot water. In case that a temperature of the temperature sensor 22 is less than a set value, a microcomputer type controller 24 may perform an operation of a hot water side heat pump 2 in such a way as an amount of remained hot water within the hot water storing tank 1 is kept constant. Then, in case that it is more economic to fill the hot water storing tank 1 with hot water at night having a low electrical fee, it is judged by a temperature sensor 21 whether the tank is full of hot water or not. If a temperature of the temperature sensor 21 is less than the set temperature, the microcomputer type controller 24 may operate the heat pump 2 until the amount of remaining hot water within the hot water storing tank 1 is replenished to the full.
