IPC: H01L21/338
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To change the maximum output of a semiconductor device in the wide range by setting the total gate width of the gate electrode of each field effect transistor(FET) in the different length, and providing the means which supplies the drain voltage for the respective FET unit at the same time. SOLUTION: A semiconductor device 19 comprises a first FET unit 20 and a second FET unit 21. A first unit source electrode 23 and a drain electrode 24 are set at the gate width Lg1 of a gate electrode 22. A second unit source electrode 31 and a drain electrode 32 are set at the gate width Lg2 of a gate electrode 30. They are set as likewise respectively. The gate width Lg1 is made shorter than Lg2. When the FET unit 20 is operated, the constant drain voltage is supplied to the drain electrode 24 through a first drain pad 29. When the second FET unit 21 is operated, the voltage is applied on the drain electrode 32 via a second drain pad 35.

Title: Harness
Inventor: ISHIHARA SHUSUKE
IPC: B60R16/02
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a harness resistant to the fold. SOLUTION: Plural parallel hole parts 154 are formed longitudinally in an outer skin part 152 of the harness 10, and lead wires 156 are longitudinally and slidably contained in the hole parts 154. When the harness 10 is folded around the width directional axis to partially change the axial lengths of the internal circumferences of the hole parts 154, if the lead wires 156 within the hole parts 154 cannot follow the fold, the lead wires 156 are longitudinally slid to the outer skin part 152. Thereby, an excessive stress does not concentrate on the lead wires 156, which prevents occurrence of cracks and breaking of the lead wires 156.

Title: Image encoder
Inventor: SUZUKI TOSHIHIKO
IPC: H04N7/30
Filed: 1994-09-02
Abstract: PURPOSE: To provide an image encoder capable of reducing a noise adaptively on visual characteristic for a color. CONSTITUTION: Orthogonal transformation is applied to an 8×8 picture element block 1 by a DCT device 2. and DCT coefficient data 7 is added on an NR(noise reduction) device 20. A DC coefficient device 22 discriminates the color based on a DC coefficient 21 out of DCT coefficients. and generates color information 23 for the color. The NR device 20 performs NR when the color information 23 shows the color of an axis I system, and performs no NR when it shows the color of an axis Q system. Image data to which the NR is applied is encoded after being quantized. In this way, the noise reduction can be performed corresponding to the visual characteristic of the color, which improves picture quality.

Title: Laminate for high frequency
Inventor: HEIUCHI TAKAHIRO
IPC: B32B15/08
Filed: 1988-08-24
Abstract: PURPOSE:To improve high frequency performance by keeping resin composition, which contains polyphenylene oxide, crosslinkable polymer and/or conomer, and crosslinkable prepolymer, at a specific temperature so as to make it into a compact or impregnate a substrate with it, and next doing primary formation and secondary formation. CONSTITUTION:Resin composition which contains polyphenylene oxide, crosslinkable polymer and/or monomer, and crosslinkable prepolymer is kept above 40 deg.C so as to make it into a compact or impregnate a base material with it. The polyphenylene oxide is relatively high in glass transition point and is thermosetting resin with low permittivity and with low dielectric loss factor. The resin composition containing the polyphenylene oxide is made to contain the crosslinkable polymer and/or monomer excellent in high frequency performance. And primary formation is done at a temperature that the resin component becomes the fused condition, that is, at 70-140 deg.C. Next, to completely harden it, secondary formation is done at 170-190 deg.C. And it is to be desired that this primary formation should by done for 10-40 minutes and the secondary formation for 60-120 minutes. Hereby, the contraction during hardening is small and the internal stress lowers, therefore the interlayer bonding force of a laminate and the metallic foil adhesive strength improve.

Abstract: PURPOSE:To uniformize working quality by providing an approach section and die hole section on the die hole section, controlling an approach angle within a prescribed angle in the range where the inner diameter of the approach section is specified fold of the inner diameter of the die hole section. CONSTITUTION:The approach section 12 and die hole section 13 are formed continuously on the hole part of the drawing die 11. At this case, in the range where the diameter (d0) of the approach section 12 is 1.05-1.20 fold of the diameter (d1) of the die hole section 13, the approach angle alpha1 is controlled to be <=4 deg.. Further, between that part and the die hole section 13, the approach angle alpha2 is formed to be >4 deg. and to become larger gradually. By this method, because the approach angle of the part where the blank stock is contacted with at first is small, the uniformized wire drawing is performed, generations of a seizure, etc., are reduced. Therefore, the quality of the wire drawing is uniformized.

IPC: B25B23/151
Filed: 1986-09-06
Abstract: PURPOSE:To enable safe and sure plastic range tightening by watching the increase amount of torque of a bolt being tightened, and facilitating correction for an angle of following turn, in case of controlling the turning angle of connecting rod/bolt in a internal combustion engine. CONSTITUTION:A torque increase amount T6 per unit turning angle of a bolt is constantly watched during its fastening operation. The torque value which loses more than a certain torque amount (T7) or more is regarded as a following turn start point T8, while the torque value which is resumed within the range of a certain torque amount (T9) is designated as a following turn end point T10. A turning angle amount A4 from the start point T8 to the end point T10 is added to a set turning angle A5, then correction is carried out to an angle A6. Actually, such a control method is adopted that the angle from the following turn start point T8 to the end point T10 is not counted. In order to minimize erroneous control caused by wavy swell resulting from noise, the correction by following turn should be performed once a cycle of fastening.

Filed: 1982-12-02
Abstract: PURPOSE:To improve purification effect of exhaust gas by providing ejector effect variable boards at the downstream of two filters thereby improving combustion of particulates and reducing choking. CONSTITUTION:The downstream side of filters 2A, 2B are partitioned into two by a partition wall 7 then a rotatable ejector effect variable board 9 is provided at the outlet. During catching of particulates by means of a filter 2A, the variable board 9 is pushed up in proportion to the gas flow through the filter 2A while at the variable board 9, particulate combustion gas G where particulates from the filter 2B have been burnt is sucked by exhaust gas E after passing through the filter 2A. In other words, the ejector effect overcoming against the resistance of rear exhaust tube 10, to flow out exhaust gas E through the filter 2A will cause negative pressure in the rear chamber of filter 2B thus to increase the suction effect as the exhaust gas flow through the filter 2A increase without causing damage on burner combustion and to increase residual air flow resulting in improvement of combustion of carbon particles in filter 2B.
