Patent number: 5443994Abstract: A bipolar transistor and a PMOS device achieves improved performance through the use of borosilicate glass (BSG) as the sidewall spacer material. The sidewall spacer material also is used for injection of boron into adjacent substrate material for forming shallow p+ doped junctions. By using diffusion from the BSG to form and/or maintain (during subsequent processing) a bipolar base region, or a PMOS source and/or drain region, rather than ion implantation, a base region is formed which is both shallow and has a low sheet resistance.Type: GrantFiled: September 23, 1994Date of Patent: August 22, 1995Assignee: National Semiconductor CorporationInventor: Alan G.

Patent number: 5444460Abstract: A circuit for reducing the number of times a character read-only memory (ROM) in a video display must be accessed in order to display outlined characters. For each pixel on a scan line in a character to be displayed the circuit outputs information on the current scan line and the scan lines above and below the current scan line. The pixels above and below the current pixel on the current scan line are summed and output as a single value. Thus, the number of accesses to the character ROM is reduced from three to two.Type: GrantFiled: October 15, 1993Date of Patent: August 22, 1995Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Shigeaki Fujitaka, Akio Kiji

Patent number: 5442606Abstract: An apparatus for the dynamic positioning of an objective lens in an optical disk drive comprises a housing, a lens unit movable in a focusing and a tracking direction, a magnetic circuit mounted to the lens unit for creating a first magnetic field, a pair of current conducting coils mounted to the housing and arranged orthogonal to the first magnetic field, and a flexure for flexibly supporting the lens unit in the housing. An active region comprising at least half of the coil creates the second magnetic field in response to current passing therethrough to interact with the first magnetic field and apply a force to the lens unit. This efficient coil arrangement allows for a small, lightweight dual-purpose magnetic circuit which substantially reduces the weight of the lens positioning apparatus. The housing is a one-piece injection molded ceramic component which maximizes stiffness and minimizes weight to improve the performance of the apparatus.Type: GrantFiled: June 13, 1994Date of Patent: August 15, 1995Assignee: Hyundai Electronics America, Inc.Inventors: Martin McCaslin, Brad Johnson

Patent number: 5442757Abstract: A pipeline control system is distributed over the functional units (15, 17, 20, 25) in a processor (10). Decoder logic (12) issues operations, each with an associated tag, to the functional units, with up to n operations allowed to be outstanding. The units execute the operations and report termination information back to the decoder logic, but do not irrevocably change the state of the machine. Based on the termination information, the decoder logic retires normally terminated operations in order. If an operation terminates abnormally, the decoder logic instructs the units to back out of those operations that include and are later than the operation that terminated abnormally.Type: GrantFiled: March 3, 1993Date of Patent: August 15, 1995Assignee: NexGen, Inc.Inventors: Harold L. McFarland, David R. Stiles, Korbin S. Van Dyke, Shrenik Mehta, John G. Favor, Dale R. Greenley, Robert A. Cargnoni

Patent number: 5441085Abstract: An insertion device for a series-shed loom having a rotor including combs (2) and shedding members for guiding the warp threads (3) over a predetermined angular region for shedding. The insertion device has a laying bar (10) with recesses (24) to guide the warp thread (3). It is moved to and fro parallel to the rotor by a drive mechanism for inserting the warp threads (3) into the shedding members on the rotor. Each laying bar (10) is associated with a guide bar (25) for deflecting the warp thread (3) for aligning it with the recess (24) in the laying bar (10). As a result the laying bar (10) is advantageously relieved of most of the warp thread tension and only directs the warp just parallel to the rotor. The laying bar (10) may consequently have a low mass.Type: GrantFiled: November 19, 1993Date of Patent: August 15, 1995Assignee: Sulzer Rueti AGInventors: Andreas Hunziker, Rudolf Frischknecht

Patent number: 5442565Abstract: Real time in-process data is collected to determine the contour and position of the interface between dissimilar layers of material. A control system is automatically programmed, based on the determined contour and position of the interface, to autonomously control the trajectory of a cutter through a conventional motion control system to separate the dissimilar layers of material. The motion control system controls the cutter movement through, for example, a conventional linear motion device including a servomotor, lead screw, and slidable carriage that holds the cutter.Type: GrantFiled: April 30, 1993Date of Patent: August 15, 1995Assignee: SeamXInventor: Zev Galel

The disk has regions with differing properties with respect to electromagnetic energy. The apparatus includes first means for emitting a first sequence of electromagnetic energy pulses in a first direction toward the disk. The first emitting means are mounted on the first structure adjacent a first side of the disk. The apparatus also includes second means for emitting a second sequence of electromagnetic energy pulses in a second direction toward the disk, the second emitting means also being mounted on the first structure adjacent the first side of the disk. The first and second directions are such that the first and second sequences of electromagnetic energy pulses reflect from the first side of the disk in different areas, the areas being separated in the direction of rotation of the disk.Type: GrantFiled: June 1, 1993Date of Patent: August 15, 1995Assignee: EnScan, Inc.Inventors: Myron I.

Patent number: 5441803Abstract: This invention relates to a method for forming, and constructs of, bonded composites of single crystal materials. The method comprises the steps of optically contacting the surfaces of the single crystal materials selected to form an assembly, bonding the surfaces by gradually heating the assembly to a temperature and for a duration sufficient to diffusion bond the surfaces, and cooling the bonded assembly at a rate which avoids thermal shock and allows the removal of stress by annealing. No bonding agents are necessary. Moreover, since the bonding temperature does not have to reach the substances' melting or fusing temperature, minimal distortion and displacement of the surfaces results.Type: GrantFiled: July 29, 1992Date of Patent: August 15, 1995Assignee: Onyx OpticsInventor: Helmuth E. Meissner

Patent number: RE35016Abstract: A three-axis force measurement stylus includes a housing and a cartridge and an interface between the housing and the cartridge wherein the interface comprises a plurality of pressure sensitive sheets, preferably of variable resistance pressure sensitive Mylar films which sense the force between the cartridge and the housing. The cartridge and the housings are disposed at a skew angle relative to the axis of the stylus to be able to sense forces in three dimensions. In a specific embodiment, the cartridge forms a conical section which mates with a complimentary conical section of the housing. Membranes of the force sensitive material are provided along three fingers from an apex of the conical section. The cartridge is preloaded against the conical section by a spring between the housing and the cartridge. Alternatively to the force sensitive film, a sheet of a piezoelectric pressure-sensitive material may be substituted.Type: GrantFiled: January 30, 1992Date of Patent: August 15, 1995Assignee: SRI International, Inc.Inventors: Larry S.
