Title: Locking mechanism for bicycle
Inventor: ISHIDA SHOJI
IPC: B62H5/00
Filed: 1993-04-16
Abstract: PURPOSE:To obviate a locking operation by providing a lock body on a fixing plate fitted to a rear axle and journaling a stand, retreating the lock body through abutting to a projecting body projectingly provided on the stand in the standing process of the stand, and advancing the lock body at completing standing so as to lock the projecting body. CONSTITUTION:When a stand 2 is operated to stand, a projecting body 21 abuts to the side wall 32 of a lock body 3, so as to retreat the lock body 3. At that time, the projecting body 21 presses the lock body against the resiliency of a winding spring 34, and the inner face of a side wall 32 is approached to the circular arc edge 13 side. When the projecting body 21 is passed through a bending point 35, the projecting body 21 enters the territory of circular arc 311. The lock body 3 is rotationally moved around a shaft 33, released from pressing of the projecting body, returned to the initial position by the force of the winding spring 34, and locked with the projecting body 21. Hereby, the stand 2 can not fall down by locking. When a bicycle is used, a cylinder lock is operated to rotationally move the lock body in the unlock direction through a transmission wire 4 foe unlocking.

Title: Manufacture of integral skin urethane foam
Inventor: YAMAMOTO KENJI
IPC: C08J9/02
Filed: 1992-04-07
Abstract: PURPOSE:To obtain a manufacture of an integral skin urethane foam which can adjust easily a quantity of a foaming agent and does not exert bad influence upon earthly environment, by performing RIM molding of urethane raw materials. CONSTITUTION:Urethane raw materials are constituted of the first component containing the first foaming agent comprised of chlorofluorocarbon gas consisting mainly of polyol and having the boiling point of not exceeding 0 deg.C, the second component comprised of isocyanate and the third component containing the second foaming agent having a coloring agent, the polyol for dispersion of the coloring agent and the boiling point of at least 20 deg.C. The first foaming agent and second foaming agent do not contain specific chlorofluorocarbon. Therefore, a danger causing environmental destruction to be generated drastically is little. Then since the boiling point of the first foaming agent is low like 0 deg.C or lower, the first foaming agent is apt to be scattered and lost out of series by gasification so far as the second foaming agent having the high boiling point is not used like a conventional example. Therefore, though it becomes difficult to keep a quantity of the foaming agent constant during production, since the second foaming agent having the high boiling point is used for the third component, the first foaming agent removed through volatilization can be interpolated.

Filed: 1979-09-06
Abstract: PURPOSE: To enable the reaction or refining of liquid, by locating both the electrodes enclosed with diaphragm in the cell and forming the flow path of liquid respectively in the cell and diaphragm.  
     CONSTITUTION: When liquid flows from the liquid flowing inlet 5' of the upper cover of the electrolytic cell, the liquid flows down in the diaphragm 9 and reaches the cover 6 and flows out of the liquid flowing outlet 6'. Further, when current flows to the electrodes 7, 8, ions produced by the electrolysis migrate into other liquid through the diaphragm 9. Accordingly, required ions migrate from one liquid to another among two liquids, a substance is produced by the electrochemical reaction as a liquid with high purity. Further, refining can be achieved by allowing the impurity ions to migrate from one liquid to another liquid, and if the two liquids are of the same kind, the concentration of the liquid can be increased.
