Title: Quality evaluation method for carbon material
Inventor: EBARA KOJI
IPC: G01N27/00
Filed: 1991-05-15
Abstract: PURPOSE:To make it possible to simply evaluate the degree of contents of impurities in a carbon material specially such as dopant impurities of boron, phosphor and others. CONSTITUTION:A carbon material 4 and a silicon wafer W are placed in adjacent to each other; an epitaxial layer is grown on the silicon wafer W; and electric resistance is compared between the first measuring portion close to the carbon material 4 of this epitaxial wafer 4 and the second measuring portion which is at least 3 cm away from the first measuring portion. Or the electric resistance is compared between the target silicon wafer W, on which an epitaxial layer is grown in adjacent to the carbon material 4, and a reference silicon wafer on which an epitaxial layer is grown independently.

Abstract: PURPOSE:To prevent abnormal variation of a can by disposing a pressure regulating member made of an elastic material in a case connected with a frame in the can, thereby suppressing the pressure difference between the interior and the exterior of the can. CONSTITUTION:A case 25 is composed of a mounting unit 27, and a cylinder 29 disposed axially between a frame 1 connected with the unit 27 and a can 3 and having a hole 28 at a stator 2 side. A cylindrical elastic material 31 is provided in the cylinder 29. When insulating oil B around the stator 2 largely expands due to temperature rise, the expansion of the volume is released through the hole 28 of the case 25 into the case 25. Since the interior of the room 32 of the material 31 is connected through the holes 21, 24, 26, the chamber 23 and a connecting slot 11 with the periphery of a rotor 12. Accordingly, the material 31 is compressed until the pressure around the stator 2 becomes substantially equal to that around the rotor 12.

Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent short circuit in soldered portion between lands by providing a bend portion forming solder storage space in a lead bend portion or a portion from the bent portion to a packaged end portion. SOLUTION: A slantwise packaged semiconductor device 2 has a bend portion 15 forming solder storage space 14 open on a package surface side, in a bend portion 6 of a lead 4 or a portion from the bend portion 6 to a packaged end portion 11. If solder packaging is performed with respect to a packaging substrate 3, solder on the lands of the packaging substrate 3 is sucked within the solder storage space 14 and set there. Accordingly, the solder does not overflow sideways, and contact between solder between adjacent lands or close adjacency, lowering reliability, does not occur. Further, as the solder does not climb via the lead 4 to the side of a package 17, short circuit phenomenon in an insulating film does not occur.

Abstract: PURPOSE:To prevent the heat generation of a gradation voltage generation circuit and the disconnection of wiring and to reduce the distortion of a gradation voltage waveform by timely switching gradation voltages to be impressed to gradation voltage input lines. CONSTITUTION:The voltage state of plural gradation voltage input lines 13 connected to a driving circuit 8 for driving a liquid crystal panel 1 is switched to the prescribed gradation voltage at every fixed time.
