Inventor: ONO TAIICHI
IPC: H01H1/36
Filed: 1990-10-31
Abstract: PURPOSE:To stabilize the force of a rare metal contact to push a resistor and enhance reliability of this invention as a contact by extending a base member along a surface on which the contact is slid, and also connecting the rare metal contact to the base member in the direction roughly perpendicular to a position of the contact where it makes contact with the surface on which the contact is slid. CONSTITUTION:The end portion of a base member 13 to which a rare metal contact 14 is fixed is parallel to a resistor 11 and is bent so that the contact 14 is roughly perpendicular to a sliding surface, for the purpose of making uniform a pushing force exerted on the rare metal contact 14. A sliding contact is extended in such a way as permitting the base member 13 to slide on the surface of the resistor 11 and also the rare metal contact 14 is formed in this extended portion whereby the base member 13 can be made longer than usual. Therefore the base member 13 made of an elastic member can stabilize a pushing force for the resistor 11 at its end portion, i.e., where the rare metal contact 14 is fixed. Reliability of the invention as a contact can thus be enhanced.

Title: Liquid crystal display driving method
Inventor: YASUI MASARU
IPC: H04N5/66
Filed: 1986-12-08
Abstract: PURPOSE:To make flickers in the case of interlaced scanning unnoticeable by switching the voltage drive direction at the time of switching frames by combining a first kind of in which the voltage direction is not changed and a second kind of frame in which the voltage direction is changed. CONSTITUTION:The first kind of frame in which the voltage impression direction against a liquid crystal is not changed neither for odd-number fields nor even- number fields the second kind of frame in which said impression direction is changed for every field, are combined to form one cycle with four frames; said voltage impression direction is changed at the time of switching the frames. This means that, during the second field, a negative directional voltage is impressed, but in a third field where the frame is shifted from the first kind to the second kind, the voltage is impressed in the positive direction. Similarly, in a fourth field, the voltage is impressed in the negative direction, but in a fifth field where the frame shifted from the second kind to the first kind, the voltage is impressed in the positive direction. As a result, the direction of voltage impression is inverted in 45Hz field frequency out of 60Hz, and flickers accordingly come unnoticeable.

IPC: G07B17/00
Filed: 1994-11-28
Abstract: PURPOSE: To clearly display a weight by inputting a prescribed key in the state where a message is displayed on a display part, judging the weighing data from a scale part is zero point or not by a weight judging means, and switching the message display to a weight display based on the weighing data by a weight display switching means when the zero point is judged. CONSTITUTION: When a key 15 is inputted while a message is displayed, the message display is released, and it is judged by a weight judging means whether the load corresponding to the weighing data from a scale part is zero point or not. When the load is judged to be the zero point, a weighing operation (weight, unit price, and amount) is displayed on a display part 14 by a weight display switching means. When the load is judged not to be the zero point, an error is displayed, but no weighing operation is displayed. When the zero setting conforming to this error display is precisely performed, the weighting operation is displayed, whereby the display of weight, unit price and amount and the message are switchingly displayed as occasion demands by use of one display part 14 to perform a clear weight display from zero point.

Abstract: PURPOSE: To enhance the calmness of a sheet conveyance device by providing a moving member for assisting the bend of a sheet by moving while abutting on the surface of a sheet, namely, a paper sheet to reduce an impulsive sound generated when the paper sheet forms a loop. CONSTITUTION: A paper sheet supplied one by one from a cassette reaches a second register roller 2 and its tip is detected by a paper detection sensor 13 and after that, it runs against a first register roller 1 which is stopping and waiting. At the same time, a solenoid 24 is turned on, thereby rotating a lever 21 to make a roller 23 enter a paper conveyance path which is held between a lower guide plate and an upper guide plate 12. The loop of a paper sheet is pushed up in the direction perpendicular to the advancing direction of the paper sheet, thereby forming a loop before the paper sheet by itself is buckled up. A loop is forcibly formed in the paper sheet, thereby reducing an impulsive sound generated when the paper sheet is buckled.
