Patent number: 4477945Abstract: Slubbing, which is to be drawn, is pulled from cans (25), which are mounted behind a drawing frame. The frame comprises a double draw head section with devices for filling two cans (7 and 8), which are situated at respective filling stations. The filled cans (7 and 8) are then automatically replaced by empty cans (2): A slide (15 and 16) moves two empty cans (2) rectilinearly, counter to the working direction of the draw heads, into the filling stations and simultaneously moves the filled cans (7 and 8) rectilinearly in the same direction into two removal stations (13 and 14). Thus, the replacement of the cans (7 and 8) proceeds very rapidly and with a minimal gap between the filled cans (7 and 8) and the empty cans (2), which avoids the need for the frame to be stopped. A device (M and H) for controlling and driving the frame is accommodated in a rear part (6) of the frame housing which is situated on the side of the removal stations (13 and 14) facing the filling stations (7 and 8).Type: GrantFiled: August 18, 1982Date of Patent: October 23, 1984Assignee: Heberlein Hispano SAInventors: Louis Vignon, Alf Schopper

Patent number: 4477963Abstract: Semiconductor electrode structure with low parasitic capacitance and method for forming low capacitance first and second electrodes in a semiconductor device, such as a static induction transistor, while avoiding the requirement for precision mask alignment and mask to mask registration. During formation of electrode contacts, the first electrodes are protected by silicon nitride and a low resistivity silicon layer is grown over the semiconductor wafer, forming epitaxial regions over the second electrodes of a polycrystalline region over protected portions of the wafer. The silicon layer is selectively etched by a mixture which removes the polycrystalline region but does not appreciably affect the epitaxial regions. Second electrode metallic contacts are made in enlarged regions of the second electrodes where mask alignment is not critical. The reduction in contact window overlap by metallic contacts reduces parasitic capacitance.Type: GrantFiled: February 17, 1983Date of Patent: October 23, 1984Assignee: GTE Laboratories IncorporatedInventor: Adrian I. Cogan

Patent number: 4477965Abstract: The invention proposes a process for manufacturing a monolithic integrated circuit comprising at least one bipolar transistor in which the dopings of the regions are inserted into the substrate (2) exclusively by way of ion implantations. The invention deals with the problem of the current gain value variations during mass-production. This problem is solved in that during the implantation of the base dopings, in which the base area (32) is defined by means of a photoresist mask (5), the emitter area (11) is covered with an oxidation masking layer portion (71), with the ions of the base region (3) being implanted into the substrate surface once at a low accelerating energy and a great dose, with the oxidation masking layer portion (71) serving as the mask and, the next time, at a high accelerating energy and a relatively small dose, in the course of which the oxidation masking layer portion (1) is penetrated.Type: GrantFiled: August 3, 1982Date of Patent: October 23, 1984Assignee: ITT Industries, Inc.Inventor: Lothar Blossfeld

Patent number: 4477967Abstract: A conductor of a rectangular cross-section is overlapped with an insulator having a greater width than the width of the conductor and wound to form a coil assembly. The oversized portions of the insulator are folded and cemented together. The coil assembly is mounted on a stator pole core so that the folded insulator portions are respectively adjacent to the pole piece of the core and to the inner wall of a cylindrical yoke when the pole core is secured to the yoke. The folded portions of the insulator are depressed by an amount sufficient to allow the coil assembly to be firmly clamped in position.Type: GrantFiled: August 23, 1983Date of Patent: October 23, 1984Assignee: Nippondenso Co., Ltd.Inventors: Susumu Yabuoshi, Shogo Uzura, Nobuyuki Hayashi
