Title: Measuring device for dynamic characteristic of switch
Inventor: OKINO TADASHI
IPC: G01R31/327
Filed: 1981-01-16
Abstract: PURPOSE:To enable to perform a reliable measurement of a dynamic characteristic through the separation of chattering and contact resistance, by a method wherein voltages, corresponding to a contact resistance and a reference resistance of a switch, are compared to form a time width signal by means of a dif- ference between the two voltages, an the signal is compared with a standard value. CONSTITUTION:With a switch 1 closed, a contact resistance reduces gradually, and an applied voltage falls. An output of a comparator 5 is inverted to a high level to set s FF 9, a counter 25 counts a frequency dividing output, and simultaneously, an AND gate 15 opens. If the contact resistance of the switch 1 falls further to a reference value, an AD gate 17 opens through the working of a comparator 7, a counter counts the frequency dividing output until the FF 9 is reset after the counter 29 performs a given number of countings, and this forms a time width signal corresponding to a difference in voltage based on the difference in contact resistance of the switch 1. Meanwhile, if chattering occurs, the counting operation of the counter 29 is controlled in a similar manner to separate the chattering from the contact resistance, and the dynamic characteristic of the switch is measured reliably through comparison of the time width signal with a standard value by means of a comparator 33.

IPC: G01R27/02
Filed: 1990-01-11
Abstract: PURPOSE:To miniaturize a device and to improve easiness of operation, reduction of inspecting cost and quickness of inspection by detecting a leak defect of capacitor to be inspected and a defective contact to the capacitor to be inspected, based on a contact confirming value and leak detecting value. CONSTITUTION:A DC voltage is impressed on the capacitor (DUT) 10 to be inspected from a power source 14 for inspection of the leak, and a current of DUT 10 is subjected to sample-hold by a sample-and-hold circuit 38 and outputted as the contact confirming value. After a specified time is elapsed further, the current value of DUT 10 is fetched by the circuit 38 and outputted as the leak inspecting value. In the case the contact to the DUT 10 is defective or the wiring is disconnected, the current is not supplied to an amplifier 18 for leak measurement due to the no current to flow into the DUT 10. That is, the output of circuit 38 becomes the value indicating that an electric charging is not being made for the DUT 10. Consequently, the leak defect of DUT 10 and the defective contact to the DUT 10 can be detected from the contact confirming value and leak inspecting value.
