Title: Electric discharge machine
Inventor: IMANAGA AKIYOSHI
IPC: B23H1/02
Filed: 1985-06-21
Abstract: PURPOSE:To improve the generating frequency of a normal discharge so as to increase a machining speed, by eliminating an abnormal discharge to disappear in an early stage through a pulse control device. CONSTITUTION:A control circuit 6, when it receives a signal of arc short-circuit abnormal conditions from a discriminator circuit 8, immediately turns off a switch 4 to be turned on after the second pulse off time. The discriminator circuit 8 discriminates a gap condition, and this action is repeated till generation of the arc signal disappears. Further in this case, even if the switch 4 is turned off immediately after the arc signal is generated, the control circuit 6, generating a current pulse for a period exceeding the generation period of a check pulse, performs the action removing a connection arc discharge by preventing a machined surface from damage. Accordingly, a machine, increasing the frequency of a normal discharge as a whole, enables a machining speed to be increased.

Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To easily treat even a high viscosity org. waste, etc., by mounting a scattering means and an agitating means on a runing rail placed at the upper edge part of a treating tank side wall, scattering the org. waste, etc., with the scattering means, then agitating with the agitating means. SOLUTION: A scattering frame 7, in which the org. waste, etc., crushed with a crusher 2 provided with a hopper is filled, is advanced. When the scattering frame 7 is brought into contact with a limit switch on the side surface of the runing rails 9a and 9b, a scattering door is opened, and the scattering frame 7 is advanced while falling the org. waste, etc., to uniformly scatter the org. waste, etc. When the scattering frame 7 is returned to the starting position, an agitation frame 8 is advanced to agitate the scattered org. waste, etc. The advanced agitation frame 8 is retreated just before the agitation frame is brought into contact with the scattering frame 1, but at that case, an agitation route is different at reciprocating passage since an agitation blade is traversed by a diameter level of an agitation shaft by an actuation of a traversing motor of a traversing frame.  Thus, even a high viscosity org. waste, etc., can be treated easily.
