Title: Electric discharge machining
Inventor: YAMADA SHIGEO
IPC: B23H1/02
Filed: 1987-07-20
Abstract: PURPOSE:To keep consumption of a tool electrode in a minimized state, by a method wherein a current value during rise of a pulse current is set to a value being 0.2-0.35 of that during fall, the inclination factor of a current with which a current value is increased to that during fall is inversely proportional to a current value during fall. CONSTITUTION:A pulse current having a pulse width tauP fed from a power source for machining to a fine gap between a workpiece and a tool electrode is prevented from steep rise in a way that a current value IB during rise is always decreased to a value lower than a peak current IP during fall and the pulse current produces a trapezoidal wave current which is increased with a positive inclination factor theta by means of a slope current IS during a time between an initial stage current IB serving as a starting point and the peak current IP. In which case, a ratio IB/IP between the initial stage current value IB and the peak current IP is set to 0.2-0.35, and the magnitude of the inclination factor theta is set in a manner to be inversely proportional to the intensity of the peak current IP during fall. This method enables improvement of machining speed in a state that consumption of the tool electrode is held at a minimum.

Abstract: PURPOSE:To balance the operation efficiency with the service life of a filter body by automatically optimizing the frequency of backwashings for each backwashing in accordance with the lower-limit differential pressure value immediately after each backwashing, namely the progress of clogging of the filter body. CONSTITUTION:The lower-limit differential pressure increment of the present lower- limit differential pressure value against the preceding lower-limit differential pressure value read out from a lower-limit differential pressure storage means 221 is calculated by a lower-limit differential pressure increment calculating means 222. The increasing rate of the present lower-limit differential pressure value against the past, namely whether the present lower-limit differential pressure increment is the maximum among the past plural lower-limit differential pressure increments read out from a lower-limit differential pressure increment storage means 223 or not, is judged by a lower-limit differential pressure increment discriminating means 224. Only when the present lower- limit differential pressure increment is judged to be the maximum, the frequency of backwashings higher than the frequency of backwashings in the conventional backwashing is specified by a backwashing frequency specifying means 225 for the succeeding backwashing.

Filed: 1987-07-22
Abstract: PURPOSE:To make it possible to form a film at a low temperature and to improve light sensitivity expressed by photoelectric conductivity/dark-current conductivity, by depositing an a-Si film on a substrate by a thermal CVD method by using disilane gas, and performing hydrogen plasma treatment. CONSTITUTION:Disilane gas as a raw material passes through a disilane gas flowmeter 5. The gas is mixed with diluting gas, which passes through a flowmeter 6 at a specified diluting rate. The gas is introduced into a reaction tube 1. The gas, which is used for reaction is exhausted through an exhaust system 8. Hydrogen plasma is generated from hydrogen gas, which passes through a hydrogen gas flowmeter 7, in a high frequency generator 9. After a substrate stage 2 is heated to a specified temperature, the disilane and the diluting gas are introduced into the reacting tube 1 at specified flow rates at the same time. Thermal CVD is performed, and an a-Si film is deposited on a substrate 4. Thereafter plasma treatment is carried out as follows: the inside of the reaction tube is substituted with the hydrogen; the temperature is set at 100-500 deg.C; and the hydrogen plasma is yielded with the high frequency generator 9. Thus, a film is formed at a temperature lower than that in a thermal CVD method using monosilane.
