Title: Cutoff lever of safety device
Inventor: SUZUKI TATSUO
IPC: F16P3/08
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a cutoff lever for a hydraulic function cutoff device capable of concentratedly working without large shaking of the cutoff lever in the random direction by the vibration or the like of an enging during working, preventing the hindrance of passage even if a worker pushes away the cutoff lever at the time of emergency escape or when the worker once leaves the operation room, and further preventing the damage of the cutoff lever. SOLUTION: When a cutoff lever 2 is fixed to the lock position, a lever part 3 is made to be displaceable only in the horizontal direction making the base point of a connecting base part 4. Further, the cutoff lever 2 is not the whole of the lever part 3, but is constituted to have a place having pliability or flexibility in the neighborhood of the connecting part 8 between the lever part 3 and the above connecting base part 4. Therefore, when a worker X leaves the driver's seat Y, the cutoff lever 2 does not prevent the passage of the worker, and the worker X can easily pass through over the lever 2.

Title: Molding and coating method of sand mold for casting
Inventor: OOTA TAKASHI
IPC: B22C3/00
Filed: 1979-11-12
Abstract: PURPOSE: To obtain a cast product of superior dimensional accuracy and casting surfaces by beforehand coating a graphite coat contg. cement on a pattern, and transfer-adhering this to the molding surface of a sand mold using cement at the molding.  
     CONSTITUTION: In the case of applying a coat on the molding surface of a sand mold, a graphite-coat contg. cement is beforehand coated on a pattern for molding using the molding by spraying etc. Thickness is about 0.2W4mm. Cement is filled in the pattern having been coated with said graphite coat, and molding is carried out. When the mold is left for a fixed time after ending of the molding, the graphite in the coat and the cement water in the sand mold cause chemical reaction and the cement water encloses the graphite and connects thereto so that the coat layer hardens and is secured to the sand mold surface. If the pattern is rapped after the hardening, the coat layer having been applied on the pattern is transfer-adhered to the molding surface of the sand mold, whereby the molding work and coating work of the sand mold are completed simultaneously.
