Title: Printed-circuit board testing device
Inventor: KAKIUCHI HIDENAO
IPC: G01R31/316
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To discharge a capacitor with the minimum discharge time by counting the capacity of the capacitor on a printed-circuit board with a count signal before inspection and performing discharge by a timer circuit. SOLUTION: When a printed-circuit board 1 mounting electrical parts and a large-capacity capacitor 8 is to be fitted, a detection circuit 2 outputs a non- supply signal for indicating that no power supply is being applied to the printed- circuit board 1. Also, a count circuit 3 performs the pulse conversion of the capacity of the capacitor 8 by a non-supply signal that is outputted from the detection circuit 2 for outputting a count signal. An oscillator 4 outputs a pulse signal with a specific frequency. Then a timer circuit 5 counts the number of count signals based on a pulse signal from the oscillator 4 and outputs a discharge signal when a specific count value is exceeded, and then resets the count value by the count signals.  Then, a discharge resistor is connected between the electrodes of the capacitor 8 by the discharge signal and the non-supply signal from the timer circuit 5 using a discharge circuit 6, and then the discharge resistor is cut from the area between the electrodes of the capacitor 8 when the voltage between the electrodes of the capacitor 8 becomes equal to or less than a specific voltage.

Title: Hair curler
Inventor: ARAI YUICHI
IPC: A45D2/36
Filed: 1993-04-15
Abstract: PURPOSE:To provide a hair curler whose surface has fine grooves running in parallel with the axis of a cylinder, where these fine grooves enable the curler to keep the moisture, and eliminate the necessity for the absorptive layer of a water absorbing material, and by which plastic forming process is simplified. CONSTITUTION:An R section 28 is responsible for cleaning the grooves 22 effectively. For instance, when an alien substance such as a hair shifts toward the groove edge 26, the alien substance moves along the R section and is discharged from the groove 22 at the groove edge 26. The water supplied to the hair curler 10 is absorbed and kept in the groove 22 by capillarity. This water is heated by the heat transmission from the stainless cylinder 14 heated by electromagnetic induction heating, and is dispersed as a vapor, which protects the hair from being short of moisture as well as realizes a comfortable curing. A water- absorptive layer such as the one made of felt is not necessary. The process of adhering such absorptive material to a hair curler surface 16 is not necessary. At the same time, as the grooves 22 can be formed in the course of plastic forming of the hair roller 10 using a synthetic resin such as polyester elastomer, its manufacturing process is simplified.
