Title: See-saw electromagnetic relay
Inventor: IKEDA SUEJIRO
IPC: H01H51/24
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To reduce the consumed power for driving and enhance the production efficiency by forming at least one side of a movable spring as a pair of bi-prong contact pieces having movable contacts, providing a step, and thereby facilitating matching to a magnetic attraction force. SOLUTION: The spring part of a movable spring 2 led out from a holding part 1d is bi-pronged on the way on one side, and at the tips, movable contacts 3a, 3b are installed. Two contacts 3a, 3b and 4a, 4b are furnished on contact pieces 2a, 2b and ac at the ends of this spring 2, and a bi-pronged contact is accomplished. At the level of this bi-pronged contact, a step H is provided so that the distances from the contacts 3a, 3b to a stationary contact 5 differ, and a continuous contact is formed by varying the contacting/separating timing of the bi-prong contacts. This gives a load characteristic flat and having a less load energy, which facilitates matching to a magnetic attraction force, reduces the consumed power for driving, and allows enhancement of the production efficiency.

Abstract: PROBLEM TO BE SOLVED: To enable screening effectively a data holding characteristic and to enable coping with deterioration in the case of deterioration of a characteristic during use. SOLUTION: In this method, threshold voltage of a memory cell is gradually varied by applying a write-in pulse at the time of write-in of data before baking, and threshold voltage of a memory cell is discriminated whenever a write-in pulse is applied. Then, when this threshold voltage is the upper limit value or more, after threshold voltage is dropped by applying an erasing pulse, a write-in pulse is applied again.

Title: Controller for fixing device
Inventor: SUZUKI SHIGEHIRO
IPC: G03G15/20
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To shorten the rising time of a fixing device in the fixing device of an equipment in which an unused driving part other than the fixing device exists at the time of rise time. SOLUTION: A selecting circuit for a direct circuit 50 and a silicon device circuit 52 is serially connected to a fixing heater 44. The term silicon device circuit means a circuit making a current flow in a forward direction in a silicon semiconductor having PN junction. Power is supplied through a direct circuit 50 at the time of starting, and power equal to or more than a power value required for fixing is generated after the starting. However, since the device part which is not energized at the time of the rise time exists, the total power consumption of the equipment at the time of the starting does not exceed the specification power value or the equipment. Since the voltage drop value of the circuit 52 is scarcely related to the flowing current, a constant voltage can be applied on the fixing heater.

Title: Developing device
Inventor: OTA TOSHIHIRO
IPC: G03G15/08
Filed: 1994-03-02
Abstract: PURPOSE:To prevent the low molecular component of a developing roller from being transferred to a photoreceptor drum so as to prevent the quality of a printed image from being lowered by forming a toner layer which is thicker than the toner layer in the case of developing processing between the surface of the photoreceptor and the surface of the developing roller after finishing the developing processing. CONSTITUTION:When printing is finished, the developing roller 1 and the photoreceptor drum 8 succeedingly rotate. A supplying roller 4 succeedingly rotates while a circumferential speed is increased from time when the printing is finished. Electrified amount on toner between the roller 1 and the roller 4 is increased by increasing the circumferential speed of the roller 4. As a result, more toner adheres on the roller 1 than usual, so that the thickness of the toner layer between the roller 1 and the photoreceptor drum 8 in the case the roller 1 and the photoreceptor drum 8 are stopped is increased. Thus, stain on the photoreceptor drum 8 caused when the low molecular component of the roller 1 is transferred to the photoreceptor drum 8 in the case of standby is prevented, so that the good quality on the printed image can be obtained.
