Title: Torch nozzle for laser machining
Inventor: KISHI MASAO
IPC: B23K26/064
Filed: 1992-02-19
Abstract: PURPOSE:To improve heat resistance and to prevent scattered fused materials from sticking to the outer wall of a nozzle by forming the main body of a torch nozzle with copper and coating a part of the outer periphery and the inner periphery of a hole with molybdenum.

Title: Ball extracting device for ball tray of pachinko machine
Inventor: KAWAI TSUTOMU
IPC: A63F7/02
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To easily extract balls from the upper and lower ball trays of pachinko machine. SOLUTION: When an upper ball extract button is pressed at time t1 by one-action operation, an electromagnetic solenoid 25 is turned off, and an opening part 24a is opened. When ball clogging temporarily occurs at time t2, the electromagnetic solenoid is not immediately returned to ON even without detecting any game ball through an upper tray ball detecting sensor 26 for a term T1(<T0). By pressing the upper tray ball extract button during ball extraction, the electromagnetic solenoid is turned on and the ball extraction can be easily stopped. When no game ball is detected longer than the prescribed time T0 by the upper tray ball detecting sensor, the electromagnetic solenoid is turned on and the opening part is automatically closed. Therefore, when starting play by supplying the game balls into the ball trays, the supplied game ball is not extracted.
