Abstract: PURPOSE:To evaluate an element substrate for each collected wafer and to improve the yield by using the conductor and drive film patterns for evaluation test to evaluate the quality of an insulated film. CONSTITUTION:Patterns 11 and 13 having shape slown in top view are set opposite to each other in their thickness direction via an insulated film, and a belt-shaped pattern 12 is set at the middle of the thickness direction of the insulated film. These patterns 11-13 are formed so that they are partially set opposite to each other in the thickness direction. At the same time, terminal parts 11a-13a having exposed upper surfaces are formed at an end of each pattern. For these patterns 11-13, probe pins are abutted to the parts 11a-13a to measure the electrostatic capacity of insulated films 5, 7 and 14 respectively.

Abstract: PURPOSE:To facilitate easy detection for a short break of a power supply of an end office by always transmitting a signal showing that the power supply of a terminal is turned on to a central end office device. CONSTITUTION:An initial program load (IPL) request is given when the power supply of an end office 2 is turned on for transfer of signals between a central end office device 1 and the end office device 2. The device 1 gives an IPL to a desired station. Then the device 1 stores the end of the IPL of the device 2 when receiving an ACK signal from the device 2. Hereafter the above-mentioned operation is repeated between the device 1 and all end office devices. Then the communication is carried out among end offices. If the device 2 has a short break of the power supply during operation, the device 2 delivers an IPL (IPL') request. Thus the device 1 knows the short break of the device 2 since the IPL' request is the second IPL request.
