Filed: 1992-03-27
Abstract: PURPOSE:To automatically generate a brake force by providing two memory means which store the set states of switches and levers at a point of time when a brake force is generated by means of a brake automatic generating means and a point of time when the generation of the brake force is stopped. CONSTITUTION:At a step S42, the set states of switches and levers at a present point of time are read. At a step S44, the set states of the switches and the levers already read at a step S31 and at a point of time when brake automatic brake control operation is started are read from a memory. At a step S46, the two set states are compared with each other and it is decided whether the two set states coincide with each other. When it is decided at the step S46 that the two set states coincide with each other, the two set states coincide with each other and when it is decided that all the switches and the levers are not switched during automatic brake control operation, a series of control procedures is completed.

Title: Ink jet printer
Inventor: IIDA YASUSHI
IPC: B41J2/175
Filed: 1986-05-07
Abstract: PURPOSE:To detect the residual amount of ink with high accuracy in a small sized in jet printer, by providing a detection means for detecting the consumption of ink on the basis of the gas exhausted from a hermetically closed type ink storage tank in the ink supply route between a recording head and said ink storage tank. CONSTITUTION:The ink residual amount detector 6 communicating with an ink tank 7 is connected to a control part and equipped with a suction means 9 such as a pump for reducing the pressure in the detector 6. When it is detected that the resistance value between a hollow needle 6-2 and an electrode 6-3 is abnormally high because of the consumption of the ink in the tank 7, an information means 1255 issues such an alarm that ink is not almost left to an operator. Corresponding to said alarm, the operator performs replacement work and, when the replacement of the tank 7 is detected by a microswitch, the pump 9 is driven to exhaust the gas in the ink residual amount detector 6 through a pump communication port 6-5 and the interior of said detector 6 is brought to a negative pressure state to introduce the ink in the tank 7 into the detector 6. This negative pressure state is held until the resistance value between the hollow needle 6-2 and the electrode 6-3 becomes low and the pump 9 is stopped.

Filed: 1990-04-19
Abstract: PURPOSE:To prevent mutual agglutination of slide contact surfaces of a pair of a fixed scroll and a rotary scroll by composing the scrolls of Al-Si alloy, and applying a tin plating to the engagement surface of one of them. CONSTITUTION:A fixed scroll 1 and a rotary scroll 2 are forged of Al-Si alloy in a high pressure hardening method, and they are cut and processed to be finished in a predetermined form. The rotary scroll is then degreased and cleaned using alkaline liquid, and it is immersed in chemical plating liquid of stannic acid soda to be plated with tin. A coating of tin plating covers rigid grains of primary crystals of Si or eutectic crystals of Si protruding from the surface to prevent direct contact of Si grains with each other or with the base alloy, so an initial conformability is improved. Mutual attachment of slide contact surfaces of the scrolls 1, 2 can thus be prevented.

Title: Device for preventing paper sheet from yawing
Inventor: OIZUMI TOSHIAKI
IPC: B65H1/04
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent paper sheets from yawing left and right when drawn out from a paper feeding part by providing a pair of paper pressers for pressing both side edges of the uppermost paper sheet so that the paper sheets drawn out at both sides of a rear part of the paper sheets may not yaw left and right. SOLUTION: The end central parts of paper sheets 4 are drawn out by a drawing roller when the sheets 4 are drawn out, so that the left and right drawing force is unstable and a rear ends of the sheets 4 sometimes yaw left or light as shown by an arrow D. The upward movement of the side edges along a pressing face 16a can be prevented because the oblique force shown by an arrow C is acted on the side edges of the sheets 4 by the inclined pressing face 16a of a pressing block 16, even when the force in the left direction shown by an arrow D acts on the uppermost sheet 4, so that the movement of the sheets 4 in the D direction can not be found. Further even when the neighborhood of the side edges of the sheets 4 are upwardly curled, the paper can be properly fed because the side edge of the sheets 4 are pressed by the pressing face 16a.
