Filed: 1989-12-12
Abstract: PURPOSE:To simplify structure and to facilitate the exchange of a unit by separating a storage area for unused toner from a storage area for toner already used by a partitioning body and housing the respective storage areas and the partitioning body into one unit. CONSTITUTION:The unused toner 5 which is previously formed is inserted in the cylindrical axis direction of the partitioning body 7 in a state where the partitioning body 7 is leftmost. Next, the unused toner 5 which is going to move counterclockwise is pressed by the partitioning body 7 and a part of the toner 5 is heated by a heater on a fixed wall 8 and conducted to a supply port 9. Then, a gap between a developing electrode 11 and a photosensitive drum 1 is filled with the heater toner and development is performed. The toner which is used for the development gets into the empty part of a container 4 where the partitioning body 7 moves from a discharge port 10. Finally, the toner 6 already used, which has nearly same shape as it is supplied, is collected by taking out the toner 6 which is cooled to be solidified. Thus, the constitution is simplified and the exchange of the unit is facilitated.

Filed: 1988-12-21
Abstract: PURPOSE:To prevent peel off of a magnet and to improve the characteristic of a rotary machine by making a recess for receiving the magnet in a magnet securing case then inserting a magnet therein and pressure securing the case to a frame. CONSTITUTION:A magnet 2 is inserted in a recess made in a non-magnetic tubular magnet fixing case 5, then the magnet fixing case 5 inserted with the magnet 2 is pressure inserted into a predetermined position of a frame 1.

Abstract: PROBLEM TO BE SOLVED: To increase the converting efficiency of a transformer by increasing the temperature of an iron core for reducing an iron loss. SOLUTION: A transformer content 1 is provided with an iron core 2, a thermal insulating plate 5 covering the whole face of the iron core 2, and a coil 7. When a fixed power is supplied to a primary coil 7a, heat is generated inside the iron core 2 due to an iron loss, and heat radiation is suppressed by the heat insulating plate 5 as a thermal insulting means so that the temperature of the iron core 2 can be increased. Thus, the iron loss can be reduced according to the increase of the temperature of the iron core 2, and the converting efficiency of the transformer can be increased. Also, the temperature of the iron core 2 can be controlled in a fixed high temperature by operating negative feedback such as the decrease of the generated heat due to the decrease of the iron loss to the iron core 2.

Title: Electrophotographic copying machine
Inventor: YOSHIKAWA SHINICHI
IPC: G03G15/20
Filed: 1989-12-13
Abstract: PURPOSE:To increase efficiency of copying operation by storing the operational condition of a start switch when the start switch is operated before a fixing device reaches a fixed temperature and automatically turning on the start switch after the fixing device reaches the fixed temperature. CONSTITUTION:When a power source switch is turned on, power is supplied only to a heat roller 16, which emits heat. However, a copying action does not start. The way that the start switch is operated is stored, and after the heat roller 16 reaches the fixed temperature, a start lamp is lit to start the copying operation. Consequently, an operator need not to wait in front of the copying machine until the fixing device reaches the fixed temperature, and he can do something while waiting. When the start switch is operated while the operator waits for the start of the copying machine main body, the copying action starts the instant that the fixing device 14 reaches the fixed temperature, thereby increasing copying efficiency.
