Title: Head cap and ink jet recording device using that
Inventor: SUGIMOTO HITOSHI
IPC: B41J2/165
Filed: 1990-04-11
Abstract: PURPOSE:To ensure that all the ink remaining in a cap is removed after suction recovery action by providing a constitution in which the interior of the cap is tapered so that the internal surface becomes smaller toward an ink discharge orifice. CONSTITUTION:A cavity part 224 which is tapered toward an ink discharge orifice 222 is provided on the internal surface of a head cap 22. If the head cap 22 begins to be used, its tightly sealed part 221 sticks to the discharge orifice surface of a recording head tightly, resulting in the creation of a hermetically closed state on the internal surface of the cap. In this case, a suction pump is activated to cause a negative pressure state in the cap 22. Subsequently, ink is sucked from each discharge orifice of a recording head 101 and the head 101 is filled with the ink. The ink runs out into the suction pump through an ink discharge orifice 222 and an ink discharge path 223. Next, the internal surface of the cap retains the ink, while the head cap 22 becomes separated from the discharge orifice surface 1 of the recording heat. Therefore, the ink remaining in the cap 22 is sucked out by activating the suction pump once again. As a result, it is ensured that all the ink remaining in the cap is removed.

Filed: 1981-06-22
Abstract: PURPOSE:To reduce friction to lessen the load, by providing a charge cam on a shaft, which is turned in accordance with turning of a film winding lever, in a film winding mechanism for camera. CONSTITUTION:The turning of a film winding lever 1 is transmitted to a gear 20, which is formed as one body together with a shaft 21, through a one-way clutch. This turning is transmitted to a gear 64, which is attached freely turnably to the shaft 21, through shutter gears 49 and 51, a sprocket gear 53, etc., and a charge cam 65 formed as one body together with this gear 64 charges a mirror and a stop mechanism. When a motor is driven, the driving force is inputted from a coupler 67 to the gear 64 in one body, and the rotation is transmitted through a route opposit to that for the manual operation and reaches the gear 20. Since the shaft 21 and the gear 64 are always turned in the same direction, friction for the winding operation is reduced to make the film winding light.

Title: Semiconductor device
Inventor: SAKURAI NAOKI
IPC: H01L29/744
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To increase the short-circuit resistance and reduce the cost by inserting a resistance between a source diffusion layer and emitter electrode. SOLUTION: The collector of a pnp transistor 3 is connected to the base of an npn transistor 2 and also emitter electrode 5 through a resistance 8 of a base layer. The base (substrate potential) of an insulated gate transistor 1 is connected to the emitter electrode 5. A resistor 4 is inserted between the source of the insulated transistor and emitter electrode 5. When a load is short- circuited to flow a high current, a voltage across the resistance 4 is generated to rise the source potential of the insulated gate transistor 1 which causes the threshold voltage of this transistor 1 to rise. Owing to the threshold voltage rise, the saturation current is controlled to improve the short-circuit resistance. Since no complicated circuit is contained, the production cost is reduced.
