Title: Measuring apparatus of partial discharge
Inventor: NAKAGAWA MASAYOSHI
IPC: G01R31/12
Filed: 1988-02-29
Abstract: PURPOSE:To remove noise from a discharge pulse accurately and to conduct highly- precise measurement of partial discharge, by providing means of discharge pulse detection, gate pulse signal generation, noise discrimination and observation. CONSTITUTION:A three-phase AC voltage being applied to cables, a pulse is discriminated from the voltage of a cable Ca by a transformer PTa, and it is amplified and converted into a pulse A of a prescribed amplitude by a binary-coding circuit 11a. After the AC voltage is stepped down, a time difference between the pulse and a processing system is corrected by a phase-shifting circuit 15a, and a signal generating circuit 16a gives a pulse every time when a phase angle of the voltage reaches a prescribed value, while a gate 17 selects these pulses and gives a pulse S1. Based on signals A-C and S1, a logic circuit 12 gives a pulse S2 of 'H' when the signals A-C are of partial discharge. Using the signals S2 and A-C, a logic circuit 13 judges the pulses to be of a partial discharge when the one-phase or two-phase outputs A-C and the signal S2 are 'H' and adds 1 to a count circuit 19. Noise can be removed accurately from the discharge pulse by using the characteristics of the phase angle and the partial discharge pulse according to this constitution, and therefore the partial discharge can be measured with high precision.

Title: Manufacture of copper junction ceramic substrate
Inventor: ITO SOTARO
IPC: H05K3/38
Filed: 1991-03-12
Abstract: PURPOSE:To enable a preform body to be joined to a ceramic substrate and a copper circuit pattern with a different coating thickness to be formed simply and surely by overlapping the copper preform body with thick and thin coating portions on a ceramic base and then heating it. CONSTITUTION:A copper thin film is formed on a surface of an aluminum nitride base 5 by chemical plating. The copper thin film is changed to a copper oxide thin film 6 by oxidation treatment. A preform body 3 is superposed on the aluminum nitride base 5 where the copper oxide thin film 6 is formed. Junction treatment is performed by heating it in a nitrogen gas environment including oxygen. Since the copper preform body 3 with a thick coating portion 1 and a thin coating portion 2 is joined by one heating treatment, an entire manufacturing process can be simplified without using a conventional method where each circuit pattern is formed according to a coating thickness of a copper plate and they are joined individually.

Title: Method for adjustment of dynamic characteristic of electret converter and communication apparatus provided with gain-adjusted electret microphone
Inventor: ANDORE JIEI BAN SHINDERU
IPC: H04M1/03
Filed: 1993-02-13
Abstract: PURPOSE: To provide a uniform reference quality value by exposing an electret transducer under the radiations of sound source and X-rays, until the sensitivity characteristic of that transducer is decreased to a prescribed value, when these acoustic sensitivity characteristics are higher than the prescribed value. CONSTITUTION: During production, a telephone system is set in an off-hook state and placed on a holding plane 9 in the processing environment that an operating current is supplied from a controller 40. The controller 40 operates a loudspeaker 60 for exciting an electret microphone 26, so as to measure the gain characteristic of transmission circuit in that telephone system. As a result, an electric/audio band signal is received by a controller 40. Normally, the electric/audio band signal is larger than a required amplitude. In such a case, this process is continued by the controller 40 and ionizing radiation rays are radiated from an X-ray source 50. Because of this radiation, the amplitude of electric/audio band signal is decreased.  When the amplitude of electric/audio band signal is decreased to a requested standard amplitude, that telephone system is removed from the processing environment.
