Title: Electric discharge machine
Inventor: ITO TETSURO
IPC: B23H1/02
Filed: 1986-06-03
Abstract: PURPOSE:To prevent accidents due to damage of an electrode, by detecting the degree of insulation of an insulative machining fluid existing in the gap between the electrode and a workpiece and by comparing thus detected value with a reference value to control the current peak value of pulses applied across the interpole gap. CONSTITUTION:A control instruction signal generating device 17 superposes high frequency alternate voltage from a rower sources 18 during a deionizing period or the quiescent time of pulse voltage applied between a wire electrode 2 and a workpiece 1 from a machining power source 15, and a current detector 6 detects interpole leakage current running due to the lowering of insulation of the machining fluid 3 which is caused by machined chips, so that thus detected current is compared with a preset reference value to discriminate the interpole condition. With the result of the discrimina tion a control instruction signal is fed to a control device 14 and the machining power source 15, and if there would be any risk that the degree of insulation of insulative machining fluid 3 is lowered so that abnormal electric discharge occurs, the current peak value of pulses applied across the interpole gap from a machining power source 15 is controlled. Thus, it is possible to prevent breakage of the wire electrode without the machining rate being lowered.

Title: Combustion control method for waste incinerator
Inventor: FUJII SATOSHI
IPC: F23G5/50
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain stabilized generating amount of steam even in a case when the nature of wastes, supplied into an incinerator, is changed suddenly. SOLUTION: The generating amount of steam of a boiler 8b is measured by a flow meter 11 and the concentration of O2 in exhaust gas is measured by an O2 -concentration meter 14. When the concentration of O2 in the exhaust gas is lower than an upper limit concentration, the amount of combustion air is adjusted in accordance with an objective amount of air based on the generating amount of steam, however, the amount of combustion air is controlled so as to coincide with the amount of air of either smaller one when an objective amount of air or the concentration of O2 has exceeded the upper limit concentration at first when the concentration of O2 in the exhaust gas has exceeded the upper limit concentration. Further, a combustion air temperature is adjusted in accordance with the low calorific power of wastes. According to this method, drying is advanced with the optimum amount of air and the condition of combustion is restored quickly even when humid wastes are supplied suddenly whereby the generating amount of steam is stabilized.
