IPC: G01R31/26
Filed: 1985-01-31
Abstract: PURPOSE:To obtain a method for inspecting automatically a waveform characteristic in a reverse direction with high accuracy by impressing a triangular wave voltage to a semiconductor element and detecting leak current near a reference voltage value. CONSTITUTION:The staircase wave voltage E1 of a DC power source 1 is impressed between the collector and emitter of a transistor Tr and the breakdown voltage value (reference voltage value) V2 when the collector current (leak current) is at a specified value is detected. The triangular wave E2 of a triangular wave DC power source 3 is impressed between the collector and emitter and the leak current is measured by an ammeter 5. The peaks value V3 of the voltage E2 is made 110% of the reference voltage value V2. The defectiveness or non-defectiveness in the rising part of the leak current waveform is detected by comparing the leak current value at E2=V1 (90% value of V2) with the reference value. The defectiveness or non-defectiveness of the inclination of the leak current waveform is detected by comparing the peak value of the leak current at E2=V3 with the reference value and the defectively oscillating element is detected by detecting the oscillation condition of the leak current at E2=V1.

Inventor: SUZUKI SHINICHIRO
IPC: H03K17/945
Filed: 1987-01-30
Abstract: PURPOSE:To prevent the time till an output transistor (TR) is turned off after the detection of overcurrent by providing a buffer circuit between a timer capacitor and a voltage detection circuit, providing a level shift TR between the two circuits and connecting a constant current circuit to an input terminal of the voltage detection circuit. CONSTITUTION:A TR 50 constitutes a level shift circuit and it is provided between a buffer circuit and a Schmitt trigger circuit. Moreover, a base of a TR 51 is connected to a base of a TR 52, the base and emitter are connected and the TRs 51, 52 constitute a current mirror circuit. When the potential of the timer capacitor 18 changes from a high voltage to zero V, a TR 48 is turned on and no current flows to the TR 50. Then, the electric charge in the base- emitter capacitance is absorbed through the TR 51 and the response till the TR 43 is turned off is quickened. When the level of the timer capacitor 18 changes from zero V to a high voltage, the TR 48 is turned off and a current flows through the TR 50. Then, nearly a half current is absorbed through the TR 51, while the TR 43 is operated sufficiently stably in the remaining current.

Abstract: PROBLEM TO BE SOLVED: To obtain a correct process result without making the same mistake again by rewriting the priority of priority information on an element which derives the process result according to whether the process result of a process part is correct or incorrect. SOLUTION: An analysis result is displayed by an update learning part 7 and if a user judges that the modification of one paragraph is incorrect, the user selects a rule which seems corrects out of grammatical rules which are already stored in a result storage part 6 or inputs a new grammatical rule. Then the priority flag 5C of the current rule is set OFF. The priority flag 5C of the rule which gives correct modification, on the other hand, is set ON. When the rule is updated and learnt, information showing whether or not the priority flag TC is ON or OFF effectively operates in next and succeeding analyzing processes. The load of a calculation quantity is smaller when the priority flag 5C is re-set ON or OFF than when the probability of a rule is changed at each time, and the immediateness of learning effect is higher.
