Title: Discharge control system at wire-cut electric discharge machine
Inventor: FUKUI MASAHIKO
IPC: B23H7/04
Filed: 1978-07-25
Abstract: PURPOSE:To unify the time basis density of discharge generation in a mechanism wherein by keeping off charge signal supplied to the switching element for condenser charging for a set period of time, repetition number of the maximum discharge is limited and breaking of wire is prevented. CONSTITUTION:Charge signal P to be given to the switching element 3 for charging finishing condenser 4 is kept off for a set period of time right after discharge. For example, rising voltage V caused by the discharge between the wire 5 and the work 6 is detected by the discharge detection circuit 7, generating a single pulse at every detection, and the discharge interruption time 8, receiving the pulse, transfers a ''1'' signal for a set period of time T to the inverter 9. AND gate 10 is closed by a ''0'' signal outputted by the inverter 9 during this period, intercepting the passage of the charge signal P thru the AND gate 10 and the charging of condenser is interrupted during the set time T. By the above constitution, number of repetition of the maximum discharge is limited below 1/T, breakage of wire is prevented, and finishing efficiency is enhanced by unifying the time basis density of discharge generation.

Abstract: PURPOSE:To achieve a stable ON action of a switch under a sufficient actuation force by composing in such a way that a second resilient body and a third resilient body having a tactile actuation property are displaced in parallel by resilient displacement of a first resilient body. CONSTITUTION:When a key top 16 is pressed down to be displaced against the spring force of a coil spring 13 from the switch OFF condition, the spring force of the coil spring 13 is increased gradually, and when the spring force of the coil spring 13 gets larger than the automatic resiliency of an inversion spring 25, the inversion spring 25 gets inverted, where an operator feels a click feeling. A lever 24 rotates clockwise about a rotary shaft 20 of a rotary holder 21, and a resilient contact part 23 presses a movable contact 4 of a membrane switch substrate 3 toward a fixed contact 6 until both contacts get in contact with each other.
