Title: Semiconductor device and semiconductor module
Inventor: GOORABU MAJIYUMUDAARU
IPC: H01L23/495
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To make a size of a semiconductor module small, along with a good withstanding voltage. SOLUTION: An outer terminal 7 is projected from a side wall of a sealing resin 2, and a heat sink 1 is exposed from a bottom face of a sealing resin 2. The sealing resin 2 surrounding a boundary edge part of the heat sink 1 has a step face 21 recessed from an exposed face of heat sink 1. When the semiconductor device is used, the exposed face of the heat sink 1 is put in facial contact with a flat face 41a of a heat radiating fin 41, while an insulating sheet 31 is put and pressed between the step face 21 and the flat face 41a under pressure. The insulating sheet 31 is formed in a way that the flat face 41a facing to the outer terminal 7 is covered with the insulating sheet 31.  Then, the height of the outer terminal 7 from the exposed face of the heat sink 1 is made smaller than a length usually defined by a rated voltage, while a withstanding voltage between the outer terminal 7 and the heat radiating fin 41 is kept constant at the rated voltage.

Abstract: PURPOSE:To make practicable measurement with a high sensitivity by removing moisture from a gaseous sample by contact with phosphorus pentaoxide, then introducing the gaseous sample to a carrier gas-entraining precut column to precut the essential components, then introducing the gaseous sample via a main column into a D type detector. CONSTITUTION:The gaseous sample after subjected to the moisture removal in a moisture removing device 1 is passed through ports L 1, L 2, a measuring pipe 2 and ports L 5, L 6 of a 6-way cock L, by which the gaseous sample is discharged. The carrier gas is simultaneously bisected and one thereof is discharged through the ports L 3, L 4 and the precut column 7. The other is introduced through ports M 3, M 2 of a 4-way cock M and the main column 4 to the detector 5 to put the same into a stable state. The 1st carrier gas is entrained therein with the gaseous sample in the measuring pipe 2 by the operation of the cock L, M and is discharged through the column 7 and this state is maintained, by which the essential components of the gaseous sample are discharged earlier than the components to be analyzed. The 2nd carrier gas entraining the components to be analyzed is introduced into the column 4 where the respective components to be analyzed are separated. The separated components are successively introduced into the detector 5 and the respective concns. are determined from the ratios between the detected values thereof and the detected values of a standard gas. The practical measurement is made with high sensitivity in this way.

Abstract: PURPOSE:To produce a logic circuit for storage of technology by generating a grant logic that can be acquired within a range where the output logic of the logic circuit is not changed and producing a physical logic circuit based on the connection information on a virtual logic circuit and the grant logic. CONSTITUTION:The input (a) of an AND gate 3 is referred to as '0, 1, 1, 0' together with the other input (b) as '0, 1, 1, 1', and the grant logic of the output (c) of the gate 3 as '0, *, 1, 0' respectively. Under such conditions, the grant logic of the (c) and the logic of the (b) are equal to 0 and the logic (c) is equal to 0 regardless of the value of the (a). The value of the (a) is not transmitted and the grant logic of the (a) is equal to *. As the grant logic of the (c) is equal to *, the value of the (a) is never transmitted via the (c) and therefor equal to *. Then the (a) is also equal to 1 in order to transmit 1 to the (c) since the grant logic of the (c) and the logic of the (b) are equal to 1. Meanwhile the (a) is equal to 0 in order to transmit 0 to the (c) since the grant value of the (c) and the logic value of the (b) are equal to 0 and 1 respectively. Thus the grant logic of the (a) is equal to '*, *, 1, 0'. In such a constitution, a logic circuit of high quality is obtained.

Filed: 1992-11-24
Abstract: PURPOSE:To produce a brass-coated steel wire contg. dispersed grains highly adhesive to rubber by plating a steel wire with brass in which unvulcanized rubber grains are dispersed in a Cu-Zn alloy plating and drying the wire. CONSTITUTION:Unvqlcanized rubber grains 1 are uniformly dispersed in a Cu-Zn alloy plating, and a steel wire is electroplated with brass. When the steel wire is then drawn, Cu reacts with Zn at the interface between the grain 1 in the plating and the brass 3 by the generated heat to form a compd. 2 such as CuxS and ZnS. Meanwhile, the grain 1 out of contact with the plating adheres to the rubber in vulcanization by which the grain is bonded to the rubber to make contribution to reinforcement by adhesion. Consequently, the adhesion of the brass plating to rubber is increased in vulcanization.

Title: Measuring method for partial discharge
Inventor: ENDO TAKESHI
IPC: G01R31/12
Filed: 1989-12-02
Abstract: PURPOSE:To safely measure partial discharge with high sensitivity by adding a high frequency transformer to the held wire of the gapless arrester between metal sheaths separating an insulating connection part (IJB) and measuring the output thereof. CONSTITUTION:When partial discharge is generated in a cable 1T at t part on the left side from an IJB 2T, potential difference is generated between sheaths on both sides and a partial discharge current flows through the internal electrostatic capacity in the gapless arrester 3T connected thereto. This current flows to the connection of the gapless arrester and an induced current is generated in the secondary winding of a high frequency transformer 6 and measured by the measuring apparatus 9 connected to detection impedance 8. A high frequency iron core 10 enhances the effective impedance of the cross bond wire between an ST and a TR and suppresses that the partial discharge current generated between the sheaths on both sides of an IJB 2T is bypassed through the bond wire 4 and simultaneously prevents the penetration of noise from the outside.
