Abstract: PURPOSE:To improve accuracy in detecting abnormality in a perforating tool by detecting the abnormality, particularly the life, of a perforating tool by the average of movement in the defined number of machining based on a load data at the rear stage of machining. CONSTITUTION:A load applied to a drill is detected from the value of a main- shaft current of a drill driving motor by a load detecting means 1, and is inputted into a microcomputer via an A/D converter 2.

Filed: 1992-04-10
Abstract: PURPOSE: To inform a host system of the presence of barrier conditions by detecting an average junction temperature of an IC device and generating electric signals, when exceeding a predetermined value. CONSTITUTION: A fundamental structure of a sense circuit is a comparator comprising transistors Q3 , Q4 , which are strong in a local junction temperature, and of which an input is a predictable voltage. The junction temperature is detected by first and second junction diode strings D3 to D6 , D7 to D10 connected so as to generate a complementary increase and decrease of an input voltage of this comparator. A voltage, corresponding to a predetermined threshold temperature, is preset by selecting a suitable resistance value, and a state of the comparator is changed by this voltage. When a state change of this comparator is detected, namely when an average junction temperature exceeds a predetermined value, electric signals are generated. Thereby, a fatal damages to the device are avoided, and the presence of barrier conditions can be informed to a host system.
