Title: Transportation system of slurry
Inventor: MOKUYA KINJI
IPC: B65G53/30
Filed: 1982-06-23
Abstract: PURPOSE:To avoid blocking of a system and easily restore the system to a normal condition, by constituting the transportation system of slurry, consisting of a slurry transport pipe and a water return pipe, in such a manner that selective use can be performed by flowing the slurry in the return pipe and water in the slurry pipe. CONSTITUTION:When a transportation pipe 18 is blocked during transportation of lump coal slurry by the pipe 18, a signal of pressure measuring units 13-17 is input to a control unit 12 and abnormality is detected. The control part 12 closes valves 2, 5, 6, 9 while opens valves 3, 4, 7, 8. In this way, the lump coal slurry from a pump 1 flows in through a pipe 45, return pipe 19 and a pipe 48 and is fed to a dehydrating pump 11. Dehydrated water flows in through a return feed pump 10, pipe 47, transport pipe 18 and a pipe 46 and is returned. By such constitution, the blocked slurry is caused to reversely flow by the dehydrated water, and blocking can be released while operation can be continued during that time.

Title: Exhaust pipe for internal combustion engine for vehicle
Inventor: EGAWA HIROFUMI
IPC: B66F9/075
Filed: 1990-04-23
Abstract: PURPOSE:To prevent personnel, equipment and materials from being contaminated by dirty water, and prevent equipment and materials from being contaminated by dust raised from the ground surface, by providing a tail pipe which turns reversibly its exhaust to a diagonally downward direction at lower temperature due to its heat sensitive deformation, and to an almost horizontal direction at higher temperature. CONSTITUTION:A one way shape-memory effect type TiNi-system alloy is wire-drawn to a coil spring 5, and the coil spring is then fixed and held at temperatures around 500 deg.C for several ten minutes to store its shape. One end of the coil spring 5 is fixed to a connecting ring 72 and the other end is fixed to one end of a coil spring 6. The other end of the coil spring 6 is fixed to a muffler 8. The coil spring energizes an L-shaped pipe part 73 through the coil spring 5 so that the pipe part is turned around an axis-line M so as for its exhaust port to be oriented downward. At lower temperatures, the exhaust port 81 of the L-shaped pipe part 73 is energized by the coil spring 6 to blow out exhaust gas. When the coil spring 5 is heated, for example, over 100 deg.C, the coil spring turns the L-shaped pipe part 73 against energizing force of the coil spring 6 which is returned to its original shape, to turn the exhaust port 81 of the L-shaped pipe part 73 in the horizontal direction.

Title: Speed controller for servo-motor
Inventor: SAKAMOTO KEIJI
IPC: H02P29/00
Filed: 1987-04-30
Abstract: PURPOSE:To improve resolution at the time of a low speed, by performing arithmetic on the estimated speed of a servo-motor through discretely fed-back speed signal, and by obtaining a storage gain in inverse proportion to the estimated speed. CONSTITUTION:So far as a speed controller is concerned, speed command is fed to a compensating circuit 2 via an adder circuit 1, and a servo-motor 3 is driving-controlled. To the adder circuit 1, an estimated speed obtainable by estimating an actual speed from the servo-motor 3 is fed back, and by the estimated speed, and arithmetic is performed on an error, and output for a speed deviation is directed to the compensating circuit 2. On the compensating circuit 2, its storage gain is varied and said estimated speed is varied. Then, an observer 4 for performing arithmetic on said estimated speed through actual speed signal W from the servo-motor 3 and torque command T is set, and said storage gain in inverse proportion to the estimated speed is set. This setting is performed by a gain setting unit 5. As this result, the resolution of speed signal at the time of a low speed can be improved.

Filed: 1983-06-17
Abstract: PURPOSE:To prevent a miscopy by detecting the erroneous feed of an original, controlling a process related to a copying operation basing on the detected output, and stopping an optical system and other process succeeding to the erroneous feed. CONSTITUTION:In case the original 3 is fed and set correctly to a prescribed position, both sensors 8, 9 detect a state that the original 3 exists, therefore, a process is not stopped and copying is executed. For instance, however, in case the original 3 is set onto a platen 1 as shown by a broken line due to the erroneous feed, the sensor 9 detects the state that the original 3 does not exist. Therefore, a fact of the erroneous feed is displayed by an erroneous feed display part, and also a process related to an optical system and other copying operation is stopped. In this way, the erroneous feed is detected securely the generation of a miscopy is prevented, and also a copy form is not consumed wastefully.

Abstract: PURPOSE:To prevent a sub-standard product due to a deviation of wall thickness and a damage of a metallic die due to a deviated load by dividing an upper punch to an outer punch and an inner punch and arranging the inner punch so that it is protruded beyond the outer punch and is movable free by backward and forward through a spring more than the outer punch so as it is protruding beyond the outer punch. CONSTITUTION:In case a blank material 1 is inclined and set above a lower punch 2, when the upper punch 4 is lowered, an inner punch 6 first pushes the blank material 1. Accordingly, the inner punch 6 corrects the posture of the material 1 by the pressing force of an urethane spring 9 at the rear end and a stroke difference of the extruded portion and an outer punch 5. Then by pressing the bottom part of the blank material against the lower punch 2 with the inner punch 6, the outer punch 5 is lowered for extrusion. Subsequently, an aperture end of the material 1 is extruded. And in the extrusion-molding, an external wall of the cup only is molded by an outer punch 5, and the punch 6 is held by an urethane spring 9 having no sufficient power for molding and it does not contribute for the molding.
