Title: Method for processing silver halide color photographic sensitive material
Inventor: FUJITA YOSHIHIRO
IPC: G03C7/42
Filed: 1988-06-20
Abstract: PURPOSE:To prevent the generation of a stain and a flaw in the photosensitive material by specifying a cross-over time between a bath having fixing ability and a washing bath or a stabilizing bath having a specified replenishing amount. CONSTITUTION:The cross-over time between the bath having the fixing ability and the washing bath or the stabilizing bath having the replenishing amount of <=1,000ml per 1m<2> of the photosensitive material s specified to <=10sec. And the distance between the carrier entrance 2 of the photosensitive material 8 and the liquid level 1 of the processing solution is reduced to shorten the cross- over distance. The air-oxidation of a fixing agent (a thiosulfate salt) contd. in the bath having the fixing ability is remarkably reduced by shortening the cross-over time to <=10sec, and the generation of a sulfide and a foreign matter is prevented. Thus, the adhesion of the foreign matter to the crossover-rack roll, etc., of an automatic developing machine, and the adhesion of the stain to the photosensitive material itself and the generation of the flaw in the sensitive material are prevented.

Inventor: DOI KAZUYUKI
IPC: F15B11/08
Filed: 1992-05-19
Abstract: PURPOSE:To improve the safety and working efficiency of a construction machine, by a method wherein both a lock valve for an arm and a check valve therefor are, in parallel, provided in the circuit in which an oil chamber on the loaded side of an arm-cylinder communicates with a pilot-operated directional control valve while the arm-cylinder is not operated, and a side pilot line is provided for the pilot-operated directional control valve. CONSTITUTION:While an arm-cylinder 40 is not operated, a pilot-operated directional control valve 44 for an arm is allowed to be at its neutral position and a side pilot 44p is allowed to be at a position (f) where an oil way communicates with a tank. Therefore, a passage in a lock valve 52 for the arm is closed since a pilot pressure is not applied to a piston chamber 52p. As the result of it, the circuit between an oil chamber 42b on the loaded side of the arm-cylinder 40 and the pilot-operated directional control valve 44 is oiltightly closed by both the lock valve 52 and a check valve 54, and the arm- cylinder 40 is locked. In this way, when a construction machine is used as a crane by attaching a lifting device in the vicinity of the top end part of the arm, such a trouble that a lifted load lowers by its dead weight can be prevented.
