Inventor: SUGA YUJI
IPC: B60K7/00
Filed: 1995-02-17
Abstract: PURPOSE: To enhance the safety by providing a floating, rotating body, which is supported by a locking member and which comes in contact with a power transmitting member for the sake of driven rotation, and cancelling the locking action of an elastic body by means of tension of the power transmitting member, which cts on the floating, rotating body, in order to lock the axle in case the power transmitting member is slackened or cut. CONSTITUTION: The locking mechanism 20 as a floating, rotating body consists of a roller 21, which comes in contact with a chain 10 for the sake of driven rotation, a square-bar-like stopper 23 as a locking member, which supports this roller 21 in a freely rotatable manner and which is attached to a bracket 11 in a slidable (movable) manner, and a coil spring 24 as an elastic member, which is interposed between the stopper 23 and the bracket 11. As far as the chain 10 is in contact with the roller 21, thereby rotating the roller 21, the position of the roller 21 in the axial direction is held at a prescribed place, resisting the energyzing force of the coil spring 24, owing to the tension of the chain 10, so that the locking action by the coil spring 24 is cancelled.

Abstract: PURPOSE: To enable fragile articles such as fruit and eggs to be picked up and dropped into a packaging container by using a plurality of grippers mounted on an endless chain.  
     CONSTITUTION: When a gripping arm 12 is at a parallel position, gripping an egg E, the upper surfaces of the arm 12 and an operating rod 27 are held by a guide regulating edge 37, so that fingers 20W21 keep gripping the egg E, and when the arm 12 is rotated from the parallel position to the perpendicular position by a shaft 13, the arm 12 and the operating rod 27 move being held by the regulating edge 37 by the upper surfaces. Thereafter, when the upper surface of the operating rod 27 is released from the end 37a of the regulating edge to enter a recess 35, the rod 27 is counterclockwise rotated about a pin 30 by the repulsion force of a spring 32, causing a movable piece 23 and movable fingers 22 to rotate counterclockwise about a pin 24, so that the movable fingers 22 separate from the fixed fingers 20 and 21 to release the gripped egg.

Title: Original conveying device
Inventor: YAMADA YASUSHI
IPC: B65H3/52
Filed: 1987-02-13
Abstract: PURPOSE:To reduce the number of parts and simplify structure by using a common driving source for the lifting/lowering mechanism of a gate member, one-rotation control mechanism of a push-out belt, and driven rotation control mechanism of a stop roller. CONSTITUTION:A gate member 7 is placed in a lifted position when originals 4 are advanced by the push-out action of a rear end restricting board 5 and, as the front ends of the originals 4 arrive at the detecting position of a stack sensor 27, the gate member 7 falls by its own weight at a certain timing and placed on the originals 4. As the gate member 7 is lowered by the reverse rotation of a shaft 11 and falls on the originals 4, a clutch lever is separated upward from the projection of a spring clutch, which, in turn, is returned to its original position by the action of a housed spring, to restrain the rotation of a stop roller 22. Also, a push-out belt 20 is put around semicircular rollers 28, 29 and sucks a sheet on the lower layer by means of a suction fan. The semicircular roller 28 obtains its driving force equally to a paper feeding belt 21 from a main motor 100 via a one-rotation spring clutch.

IPC: F28G7/00
Filed: 1982-02-26
Abstract: PURPOSE:To remove dust attached to the outer surfaces of heat exchanger tubes effectively by the function of friction caused by vibration of a dust removing net. CONSTITUTION:A dust removing net 4 is obtained by knitting a string-like member 5 of a heat-resisting material into a net-like form, and the string-like member 5 is constituted by knitted braids of a heat-resisting, inorganic textile material, tapes, tubes, etc. The dust removing net 4 consists of lateral strings 5a disposed at the same pitch as the longitudinal pitch of heat-exchanger tubes 1 and longitudinal strings 5b extended perpendicularly to the lateral strings 5a which are knitted into a net-like form. During the heat exchanging process, dust contained in exhaust gas is attached to the surface of the heat exchanger tubes 1. When the dust removing net 4 depended in hanging scroll form from net suspending metals 6 is vibrated in a self-excited manner by the pressure of exhaust- gas flow, the lateral strings 5a held in contact with the heat exchanger tubes 1 in the dust growing direction is vibrated vertically, so that dust attached to the tubes 1 is shaken off and removed. The dust thus shaken off is removed together  with exhaust gas.

Title: Electrolyte substrate and flat cell manufacturing method
Inventor: TAKATSUKI SEIJI
IPC: H01M8/12
Filed: 1994-02-28
Abstract: PURPOSE:To provide a smooth electrolyte substrate suitable for a supporting body by baking a laminated body composed of an even number of green sheets formed by doctor blade method. CONSTITUTION:Green sheets 21 with 100-300mum thickness are formed of a slurry consisting of yttria-stabilized zirconia(YSZ) with 0.1mum particle size, a binder, a dispersant, a plastisizer, a dispersing solvent, etc., by a doctor blade method. Two green sheets 21 are stuck to each other by a dibutyl phthalate while the back sides thereof at the time of film formation are positioned face to face to obtain a laminated body 22. After being dried by hot air while sandwiched between glass plates, the laminated green sheets are baked at 1300 deg.C to obtain an electrolyte substrate with 300-600mum thickness. An electrolyte substrate with sufficient thickness and suitable for a supporting body for a self-standing film type cell is obtained by laminating the green sheets which have uniform thickness since they are formed by doctor blade method. The shrinkage anisotropy of green sheets in the film thickness direction at the time of firing is offset by layering the sheets while setting the back sides of the sheets face to face and warping is prevented.
