Abstract: PURPOSE:To prevent silver from coming into direct contact with a glass insulator and to prevent development of migration by applying nickel plating to all the ends of an inner electrode conductor at the side whereon an insulating layer and an outer electrode are formed. CONSTITUTION:Conductor paste is applied to two side surfaces of a slice plate 4 excepting a cut surface whereon an inner electrode conductor 2 is exposed at every other layer to form a temporary electrode 5. Then, the slice plate 4 is immersed into nickel plating solution, and nickel plating 6 is applied to an end surface of an inner electrode conductor 2 which is exposed to a cut surface using the temporary electrode 5 as plating electrodes. Nickel plating is applied in this way to all the end surfaces of an inner conductor at the side whereon an insulating layer and an external electrode are formed; thereby, a silver electrode is prevented from coming into direct contact with a glass insulator. Development of migration can be prevented in this way.

Title: Sampling tracing circuit
Inventor: KAWAKITA HIDEYUKI
IPC: G06F11/28
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To efficiently use a tracing memory by discriminating whether valid data are written or not when tracing data are overwritten based on a trigger signal and a V flag, which are written in the tracing memory in accordance with tracing data. SOLUTION: A write buffer 5 outputs the inversion (L flag) of the trigger signal showing final write position to a data line, shows whether data are overwritten in blocks or not and outputs the overflow signal (V flag) of a lower side counter 3 to the data line. Namely, it is discriminated whether valid data are written or not in the respective blocks even if overwriting is executed by checking two bits stored with tracing data and the L flag and the V flag. Thus, it can be discriminated whether valid data are written or not even if tracing data are overwritten in the trace memory 1 at the time of sampling tracing.

Title: Holding circuit
Inventor: DOMENIKO ROTSUSHI
IPC: H03K17/00
Filed: 1988-12-22
Abstract: PURPOSE: To hold a power transistor(TR) in a conductive state at the time of service interruption by connecting a diode between the drain of a 1st TR and the gate of a power TR and respectively connecting the gate and drain of a 2nd TR to the gates of the 1st TR and the power TR. CONSTITUTION: When a feeder 2 is interrupted (VA=0), a gate capacitor CGS in a power TR MP is charged with electricity and a TR M2 is in an interrupted state. Since voltage VA is lower than the gate voltage VGP of the TR MP, a diode D is reversely biased and the discharge of the gate capacitor CGS of the TR MO is suppressed. A current is leaked only from a TR M1 having an inherent diode DM1 and the diode D and the gate capacitor CGS of the TR MP is separated from a driver 3. Thereby when power supply voltage VA is dropped, the gate of the TR MP is automatically separated from all constitutional elements of a holding circuit 1 and the TR MR is held at a permanently conductive state.
