Title: Mold forming method of lead frame and mold forming equipment
Inventor: YAMAGUCHI TATSUYOSHI
IPC: H01L21/56
Filed: 1989-12-26
Abstract: PURPOSE:To prevent generation of microgap in sealing resin by installing a bending metal mold for forming an outer lead, in adjacent to a metal mold having a resin sealing cavity and outer lead clamping parts. CONSTITUTION:A lead frame 40 of a semiconductor chip 50 is set on a lower metal mold 14, an outer lead 42 is made to protrude between a punch 30 and a lower die 32 of a bending metal mold, and a guide pin 36 is inserted into a guide hole, thereby positioning the chip. An upper metal mold 12 and the lower metal mold 14 are fastened, a base part of the lead 42 is clamped and retained with a clamping part 15, and the lead 42 is subjected to bending work between the punch 30 and the lower die 32. While the frame 40 is clamped and retained as it is, a cavity 10 is filled with melted resin, and resin sealing 60 is performed. After curing, the punch 30 and the molds 12, 14 are opened, and the package is released with ejector pins 20, 22. Since the outer lead is subjected to bending work by the same equipment before resin sealing, the generation of microgap or the like in a boundary part can be prevented.

Abstract: PROBLEM TO BE SOLVED: To obtain a new neutral xylanase capable of specifically hydrolyzing various xylanes and xylooligosaccharides comprising xylotetraose or above and providing low molecular weight xylooligosaccharide for functional food raw materials from a microorganism of the genus Acremonium. SOLUTION: This neutral xylanase specifically acts on various xylanes and xylooligosaccharides comprising xylotetraose or above and the b-xyloside bond is cleaved by end type mechanism to produce xyloologosaccharide having low molecular weight, mainly comprising xylose, xylobiose and xylotriose. Optimum pH is about 7.0 and stable pH is 6.0-10.0 when the xylanase is treated at 37 deg.C for 15min and optimum temperature is 50 deg.C and the xylanase is stable until 40 deg.C when it is treated at pH7.0 for 20min and the xylanase has about 15% residual activity even at 80 deg.C and has about 22500 molecular weight (SDS electrophoretic method) and about 4.7 isoelectric point. The enzyme is obtained by culturing Acremonium sp. TOTO-9304 strain (FERM P-13639) at pH6.0-11.0.

Title: Scroll compressor having economizer injection port in optimum position
Inventor: BUSH JAMES W
IPC: F04C29/00
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To provide the optimum position for a scroll compressor economizer injection port. SOLUTION: The positions of economizer ports 26, 28 in a scroll compressor 20 are so optimized as to supply auxiliary fluid to a compression chamber before outer seal points of the ports close the compression chamber. Accordingly, the economizer ports 26, 28 can supply fluid under low mean pressure, and the amount of fluid to be injected from the economizers is maximized. It is desirable that the positions of the economizer ports 26, 28 are selected that compression waves generated by fluid injection from the economizer ports 26, 28 may not reach the outer seal points until the outer seal points close the compression chamber. Accordingly, back flow from the economizer ports 26, 28 to a main suction chamber is not generated, and the main suction flow is not reduced with it.

Title: Manufacture of mos transistor
Inventor: SHIMIZU SATORU
IPC: H01L29/78
Filed: 1991-12-24
Abstract: PURPOSE:To obtain a large current driving capacity without limiting the area of a cell by a channel width by so setting a carrier running direction of a channel as to be parallel to a surface of a semiconductor substrate and a channel width direction as to be perpendicular to the surface of the substrate. CONSTITUTION:A gate and an element isolation part of a substrate 1 are respectively formed in a columnar well state and a groove state. The gate is oxidized, the well state gate is covered with a gate insulating film 7, and then the gate is buried with polysilicon 9. Thus, since a channel width direction is perpendicular to the surface of the substrate, a channel width can be increased by deeply digging a columnar well state hole of a gate electrode, and the area of a transistor of a cell can be reduced while holding a current driving capacity large. Further, since the gate electrode has a structure for burying it in the substrate, the driving capacity can be increased because both sidewalls of the gate electrode are used as channels.

IPC: G01R31/28
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor memory device in which a slight abnormality is judged to be a defective product by detecting a leakage current, across respective cells and across wells at a memory cell, which does not appear as a defect in output data. SOLUTION: When a test signal TE is supplied, a sense amplifier 1, an X- docoder 5, a Y-decoder 6 and charging circuits 3, 4 are stopped. Then, when a test mode signal TM is supplied, an inverter 72 outputs its level inverting signal TMB. When the signal TM is set at a high level, gate potentials of transistors Q00 to Qik are set at a high level, and their source potentials and their drain potentials are set at a low level. At this time, when a defect exists in bonding parts of word lines ML0 to WLi and in gate oxide films at the transistors Q00 to Qik a leakage current flows to a ground from the gates, a power supply current flows to the transistors Q00 to Qik via a switching circuit 74, and, even when the amplifier 1 and the circuits 3, 4 are stopped, a current in the amplifier and the circuits is increased.  As a result, when the current is confirmed, a leakage current is found out, and whether a semiconductor memory device is good or defective can be judged.
