Patent number: 4488317Abstract: A garment having a seamless crotch is described. The seamless crotch of the present invention may be used in conventional pants, such as dress pants and jeans, as well as in shorts. In conventionally lengthed pants, an essentially curved diamond-shaped crotch piece with concave edges and long tapering sections which extend down the insides of the legs of the garment is sewn into the garment.

Patent number: 4488346Abstract: A pipe and sleeve telescoped joint with the pipe and sleeve in sealing engagement and keys embedded in both pipe and sleeve at their interface. The size and number of the keys are calculated from the size and strength of the pipe. The sleeve is sized and its strength selected from the strength of the pipe, and the sleeve ends are shaped to hold the joint circular when it is made. The apparatus includes means for holding the midportion of the sleeve circular when creating the joint, and for cooperating with the sleeve ends to keep them circular. The sealing engagement is created by firing a propellant into a substantially incompressible medium, like water, held by the apparatus in a cavity about the sleeve, and a piston separates the explosive propellant from the pressure medium.Type: GrantFiled: June 22, 1981Date of Patent: December 18, 1984Assignee: Akzona IncorporatedInventor: Lee A.

Patent number: 4488347Abstract: A method and apparatus is proposed for the simultaneous joining together of a multiplicity of individual helical coils in forming a link belt section intended for co-operation with other like sections to produce a link belt of a requisite length, coils of opposite hand being arranged side-by-side in pairs and such pairs being combined together to form the section. Hinge wires are threaded through the interdigitated turns of adjacent coils to maintain the integrity of the total structure.The apparatus includes a guide means for locating the individual coils one relative to another and a roller nip arrangement through which the coils, in a requisite relative disposition, are caused to pass. Hinge wire insertion means is also provided, whereby individual hinge wires are introduced into the interdigitated turns of adjacent coils.Type: GrantFiled: July 8, 1981Date of Patent: December 18, 1984Assignee: Textiel Techniek Haaksbergen B.V.Inventor: Gerrit W.

Patent number: 4488348Abstract: A method and structure for producing a vertically built MOS structure which permits the out diffusion of dopant from a layer of chemically deposited (CVD) doped oxide into a layer of CVD laser recrystallized polysilicon is disclosed. This out diffusion is accomplished during a high temperature oxidation treatment of an intermediate structure. Source and drain mask alignment is chosen such that this out diffusion of dopant from the CVD glass at its boundary limit will meet with a diffusion of implanted ions. This process makes possible minimal overlap of the drain and source zones with the gate, thus reducing coupling capacitance while providing increased packing density.Type: GrantFiled: June 15, 1983Date of Patent: December 18, 1984Assignee: Hewlett-Packard CompanyInventor: Richard D.

Patent number: 4488349Abstract: A method of repairing shorts in parallel connected vertical semiconductor devices including a plurality of parallel-connected transistors comprises an anodizing step, before the electrodes are formed, in addition to the conventional manufacturing steps. Since defective semiconductor regions due to short circuit, poor withstand voltage or pin holes are insulated from the corresponding electrodes by an insulating material formed in the anodizing step, even if any of parallel-connected transistors are defective, the integrated circuit is usable, thus reducing the percentage of defectiveness of the vertical semiconductor devices in the assembly line production thereof.Type: GrantFiled: March 15, 1983Date of Patent: December 18, 1984Assignee: Nissan Motor Company, LimitedInventors: Koichi Murakami, Teruyoshi Mihara

Patent number: 4488350Abstract: A static bipolar random access memory cell includes first and second transistors formed in epitaxial silicon pockets 41 and 42 in a substrate. The collectors 19 and 19' and bases 15 and 15' of the transistors are interconnected with polycrystalline silicon 21 doped to match the conductivity types of the regions contacted. Undesired PN junctions 40 and 40' created thereby are shorted using an overlying layer of a metal silicide 25. In a region overlying the N conductivity type polycrystalline silicon 23 or 23', the metal silicide is removed and a PN junction 37 or 37' created by depositing P conductivity type polycrystalline silicon 35c or 35c'. If desired additional P type polycrystalline silicon 35a and 35b may be deposited across the surface of the epitaxial layer where the base regions of the two transistors are formed to reduce the base series resistance.Type: GrantFiled: October 27, 1981Date of Patent: December 18, 1984Assignee: Fairchild Camera & Instrument Corp.Inventors: Madhukar B.

Patent number: 4488351Abstract: A method for manufacturing a semiconductor device, capable of forming, with good controllability, impurity regions of a low impurity concentration, includes the steps of: forming a gate electrode on a surface of a semiconductor substrate through a gate oxide film; forming a first film on the surfaces of the gate electrode and the semiconductor substrate; forming a non-single-crystalline silicon film to cover the entire surface; forming a second film to cover the entire surface; performing anisotropic etching of the second film to form residual second films on the side walls of that step portion non-single-crystalline silicon film which is formed corresponding to a shape of the gate electrode; performing etching of the non-single-crystalline silicon film by using the residual second films as masks to form residual non-single-crystalline silicon films on the side walls of the gate electrode through the first film; ion-implanting an impurity having a conductivity type opposite to that of the semiconductor substrType: GrantFiled: January 25, 1984Date of Patent: December 18, 1984Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventor: Hiroshi Momose
