IPC: G02F1/1335
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a structure which protects a polarizing layer built in a reflection type display device against deterioration. SOLUTION: The reflection type display device is assembled by using a pair of substrates 1, 2. The first substrate 1 exists on an incident side and is formed with transparent electrodes 6.

Title: Weyl combination test circuit
Inventor: CHIYOU TERUMICHI
IPC: G01R31/327
Filed: 1994-10-27
Abstract: PURPOSE: To protect a capacitor against breakdown by connecting a resistor in series with a capacitor for regulating the transient recovery voltage delay time in a voltage supply circuit thereby preventing a high frequency current from flowing into the capacitor even if a circuit breaker to be tested flashes over with the peak value. CONSTITUTION: A resistor Ro is connected in series with a capacitor Co for regulating the transient recovery voltage delay time in a power supply circuit being connected in parallel with a circuit breaker CBT to be tested. The resistor Ro has resistance of several Ω being set to provide a delay time satisfying a regulation. Since the resistor Ro is connected in series with the capacitor Co, an unoscillating current flows through the resistor Ro-capacitor Co circuit and a high frequency oscillating current does not flow through the circuit. Consequently, the capacitor Co can be protected against breakdown.
