Title: Insert casting method for metallic parts
Inventor: SUGAWARA TOSHIO
IPC: B22D19/00
Filed: 1985-07-24
Abstract: PURPOSE:To unite a casting part and metallic part with a foamed molding as an expendable mold by tentatively fixing the metallic part into the cavity of metallic molds for expansion molding and executing expansion molding. CONSTITUTION:The metallic member (b) is tentatively fixed to a tentative fixing member 4 of one metallic mold 2 of expansion molding tools and after both metallic molds 1, 2 are closed, expandable thermoplastic resin particles are packed into the mold cavity 3 formed between the molds 1 and 2 and the expansion molding is executed. The expansion molding F formed in such a manner is then embedded as the expendable mold for casting into molding sand 6 and a molten metal is poured into the mold from a runner 60. Then the molding F is melted and expended by the heat of the molten metal and the molding F is substd. with the molten metal. The casting A of the shape corresponding to the molding F is thus produced and the metallic member (b) is embedded into the central part of the casting A, by which said member and casting are integrally bound.

IPC: H01L21/3213
Filed: 1990-06-21
Abstract: PURPOSE:To prevent generation of residual resist when a contact hole is opened in an insulating film on a second wiring film by protecting a wiring film when the hole is opened in the insulating film by a conductive film. CONSTITUTION:A thin metal film 6 is selectively formed by using catalytic actions of second wiring films 5a, 5b, which are covered therewith. Then, a third insulating film 7 made of a multilayer film of a silicon oxide film is formed, the film 7 is partly selectively removed to open contact holes 8a, 8b. In this case, the film 6 as a protective film is desirably a material which has large etching selection ratio to the multilayer film of a silicon oxide film for forming the film 7 and high volatility of reactive product with etching gas by RIE. Thus, the wiring film is protected against an overetching at the time of opening the hole to prevent generation of residual resist and to improve yield and reliability.

IPC: H03K19/0175
Filed: 1992-05-29
Abstract: PURPOSE:To obtain an output circuit protected against a short-circuit or bus contention by setting the output circuit to an output enable state or an output disable state based on an input signal, a delayed input signal and a detection signal. CONSTITUTION:When an input signal (a) is changed, a difference is caused between an output (c) of a delay circuit 1 and the input signal (a), an output (d) of an exclusive OR circuit 10 is set to 'true', an output (g) of an OR circuit 10 goes to 'true', the output circuit 2 is set to the output enable state and from which a signal (b) is outputted. The signal (b) is fed to an exclusive NOR circuit 12 through an output detection circuit 3, the exclusive NOr circuit 12 compares the signal (b) with the signal (a) and when they are coincident, a signal (f) goes to 'true' and the output enable state is maintained. On the other hand, when dissident and the output level of the delay circuit 1 is equal to the level of the signal (a), the signal (d) goes to 'false' and since the signal (f) is set also to 'false', the output circuit 2 is set to the output disable state. That is, when the signal (g) is set to 'true', no bus contention takes place and when any contention takes place, the signal (g) is set to 'false'.

Title: Paper sheet feeder
Inventor: NAKAMURA KUNIHIKO
IPC: B65H3/48
Filed: 1982-09-22
Abstract: PURPOSE:To reliably prevent multi-feeding of paper by a suction cylinder opposed to a rotary drum and to adsorb and take out the paper sheet adsorbed and stopped on a groove of the suction cylinder by rotating the rotary drum to easily separate the paper sheet from the suction cylinder by a next suction hole. CONSTITUTION:Where a suction hole 33 of a rotary drum 41 adsorbs and feed out two and more sheets of paper stacked on a placing table 28 at one time, the back surfaces of the leading end portions of the lower paper sheets are sequantially adsorbed and stopped by a suction cylinder 31, so that only the uppermost paper sheet is transported by the rotary drum 41 to prevent multi-feeding. The stopped paper sheet is stopped in such a manner as to be on a groove 32 mounted on the suction cylinder 31 in the paper feed direction. Both side ends of each groove 32 communicating with the air can considerably lessen a volumen change per a unit time in separating the paper sheet from the suction cylinder 31 by the next suction hole 42 of the rotary drum 41, so as to reduce resisting force of negative pressure caused by such volume change. Thus, the stopped paper sheet can be easily separated from the suction cylinder and adsorbed to be taken out.

Title: Semiconductor device and its manufacture
Inventor: MAKIYAMA KOZO
IPC: H01L21/318
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To protect a semiconductor element from moisture, etc., without deteriorating the high-frequency characteristic of the element by preventing the gate capacity of the element from increasing, by forming a T-shaped gate electrode having an overhang section on an element layer and covering the gate electrode with a cover film, and then, providing a clearance under the overhang section of the gate electrode. SOLUTION: A low-resistance layer 16 is formed on an electron supplying layer 14 and a T-shaped gate electrode 24 is connected to the layer 14 in a recess hole 22 extending to the layer 14. The electrode 24 is formed in such a way that its overhang section 24a is extended to the part of an area excluding the recess hole 22 above the lower-resistance layer 16. Therefore, the clearance under the overhang section 24a becomes narrower. In addition, a protective film 38 composed of an SiN film is formed on the whole surface so as to cover the gate electrode 24 and a cover film 28 is formed on the whole surface excluding the area below the overhang section 24a of the gate electrode 24. Since the clearance 26 under the overhang section 24a is narrow, the cover film 28 is not formed in the clearance 26. Therefore, the increase of the gate capacity of a semiconductor device can be prevented.

Title: Servo valve
Inventor: KATO YOSHIRO
IPC: F15B13/043
Filed: 1985-07-25
Abstract: PURPOSE:To enhance both accuracy and reliability by using an piezoelectric- crystal element for driving a nozzle flapper. CONSTITUTION:The upper end part of a nozzle flapper 11 is pivotally supported by a rotating shaft 11a so that the flapper 11 can be inclined. The inner surfaces of piezoelectric-crystal elements 14 and 15 touch both side-surfaces of the nozzle flapper 11. With this contrivance, when electric voltage is impressed, the piezoelectric-crystal elements 14 and 15 are elongated due to the piezo electric effect, thereby inclining the nozzle flapper 11. As a result, both electric power consumption and calorific values are lessened, thereby enhancing the accuracy, reliability, and responsibility.

Title: Desulfurizing method of molten iron
Inventor: YAMADA SUMIO
IPC: C21C1/02
Filed: 1982-09-22
Abstract: PURPOSE:To obtain high desulfurization efficiency particularly with the molten iron in a low sulfur region by blowing a desulfurizing agent consisting of CaCO3 powder obtd. by disintegrating limestone directly into the molten iron by using a carrier gas and desulfurizing the molten iron at a low cost. CONSTITUTION:A desulfurizing agent consisting of CaCO3 powder obtd. by disintegrating preferably natural limestone is blown directly into molten iron by using a carrier gas and the molten iron is desulfurized. The blowing of such treating agent is particularly effective for desulfurization in a low concn. region of S because a larger amt. of gas is generated from CaCO3 and the molten iron is intensively stirred. However, if the generated gas, that is, gaseous CO, is so much that the desulfurization is adversely affected, the powder mixture compounded with <=30wt% quicklime in the CaCO3 powder is used. For higher efficiency of reaction with Ca, >=1 kind of halide of alkaline (earth) metals such as fluorite, NaF, MgF2, etc. are compounded as a flux with the CaCO3 powder, whereby the slagging is accelerated.
