Title: Pipe pressing tool
Inventor: KIKURA YOSHIKUNI
IPC: B30B1/32
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To perform a pipe pressing and restoring work by oneself in small space by tilting a pinching mechanism from a state where it erects upwards to a state where it is bent a specified angle to a pinching part. SOLUTION: When repairing and exchanging a gas pipe, a worker holds a pinching mechanism 3 and places a pinching part 2 near the repairing portion of the gas pipe in a digging hole. The worker operates the pinching mechanism 3 while he holds it and pinches and moves the movable part 2A of the pinching part 2. The gas pipe is pinched and pressed by a pinching part 2 to shut off gas. After the repairing and exchanging work is finished, the worker bends the pinching mechanism 3 a specified angle to the pinching part 2 by a bending mechanism 4 and changes the pinching angle of the pinching part 2 and pinches the pinched portion of the gas pipe again and returns it.  Since he changes the pinching angle of the pinching part 2 and performs the returning work of the pinched portion of the gas pipe, the working space is nearly equal to that for pinching and pressing the gas pipe, which improves workability.

Title: Container for photographic processing agent and photographic processing agent supply mechanism
Inventor: KENMOCHI TORU
IPC: G03D13/02
Filed: 1994-12-16
Abstract: PURPOSE: To make a photographic processing agent in container flow out even when the container is set at the filling port of a tank in a state where a cap is still attached. CONSTITUTION: An outer cap 34 attached to the discharge port 30 of a container 24 is engaged with the filling port 36 of a tank 12 in which a photographic processing agent in the container 24 is put, and kept in a state where the discharge port 30 of the container 24 turns downward. The pouring port 38 of the outer cap 34 is hermetically sealed by a cover 42 attached to the outer cap 34 so as to be able to be opened/closed. An operation lever 48 is actuated along a guide groove 50 from the outside of the tank 12. Since the operating lever 48 presses the locking piece 46 of the cover 42 along the opening locus of the cover 42 just like it draws a circular arc, the cover 42 is opened and the photographic processing agent in the container 24 flows in the tank 12 through the pouring port 38. Thus, the trouble of unsealing the cap is saved and hands are prevented from being soiled.
