Abstract: PURPOSE:To decrease the leakage of a clock by detecting the leakage of a clock applied to a gate in an analog switch comprising series connection of an MOSFET switch and a capacitive MOSFET to control the phase difference of the two clocks. CONSTITUTION:If the leakage of a clock signal takes place in the analog switch comprising MOSFETs M41, M42, the same amount of the signal leakage is caused also in the analog switch comprising MOSFETs M43, M44, and the leakage is amplified by an operational amplifier OP42 and integrated by integration circuits R41, C43 and an operational amplifier OP43, the result is fed to a gate of an MOSFETM45 to change the drain-source resistance, and a clock N4 is delayed by the cooperation of a resistor R43 and a capacitor C44 to control the phase. When an output of the operational amplifier OP42 is negative, for example, an output of the operational amplifier OP43 is increased as the sample holding is repeated, the resistance value of the FETM45 is decreased, the delay of the clock to the FETs M42, M44 is increased, and the leakage error is decreased and becomes close to zero.

The auxiliary electrode 9 is made thick, so that the proportion of  the thermal-conduction loss of the electrode 9 to the stored-heat quantity of the  electrode 9 is larger than that of the thermal-conduction loss of the main electrode  7 to the stored-heat quantity of the main electrode 7. Consequently, the current  which flows when the temperature of these electrodes differ and the main electrode  7 serves as a cathode, is made larger than the current which flows when the auxiliary electrode 9 serves as a cathode.

Title: Electric discharge machining device
Inventor: NISHIGAKI HARUO
IPC: B23H1/10
Filed: 1987-01-28
Abstract: PURPOSE:To aim at enhancing the life of machining oil and at reducing the running cost by charging anion exchange resin, solely in an ion exchanger constituting a specific resistance maintaining device so as to remove anionically deteriorating products which lower the specific resistance of deteriorated machining liquid. CONSTITUTION:Ionically deteriorating products in deteriorated machining liquid have hydrogen ions and ferric ions exhibiting acid as main component when they are cations, but have organic acid ions such as formic acid ions or acetic ions as main components when they are anions. Generally, ions causes the specific resistance of deteriorated machining liquid to be remarkably lowered. If the forming acid ions form organic acid consisting of hydrogen ions and organic acid ions, the specific resistance of the machining liquid is remarkably lowered. Accordingly, if anion exchange resin 411 is charged in an ion exchanger 41, it coexists with the ferric ions so that the organic acid ions forming stable polynuclear complex salt are not removed. Accordingly, it is possible to enhance the life of machining liquid and to reduce the running cost.
