  • Publication number: 20030147530
    Abstract: An information processing system that is configured in such a manner that computational processing is performed on input data in accordance with a processing sequence, for outputting data, comprises: a plurality of arithmetic units (7-1 to 7-x), each computing at an arithmetic precision 2m bits (where m is a natural number) based on the processing sequence; and a plurality of cascade connection terminals for cascading these arithmetic units each other. When the maximum arithmetic precision that is required during computational processing is 2n bits (where n is a natural number and is fixed), x numbers of (where x is a natural number) the arithmetic units are cascaded in a manner such that the inequality x≧2n/2m is satisfied. When an arithmetic precision of 2n1 bits (where n1≦n, and n1 is variable) is necessary during computational processing, x1 numbers of the arithmetic units are cascaded in a manner such that the inequality x1≧2n1/2m (where x1 is a natural number and is variable) is satisfied.

  • Patent number: 6496524
    Abstract: A laser diode module is provided which is capable of suppressing reduction in the efficiency of laser beam coupling with an optical fiber even in the case where a warp is caused in the mounting surface of a thermo electrical cooler on which a laser diode chip is mounted. A laser diode module has a heat sink and optical coupling portion mounted directly or indirectly on a mounting surface of a thermo electrical cooler. A laser diode chip and the optical coupling portion are located on the same side of the mounting surface along the emitting direction of a laser beam emitted from the laser diode chip, with respect to a first center line (Lcpp) intersecting perpendicularly with a tangential plane tangent to the mounting surface of the thermo electrical cooler at the center thereof and/or a second center line passing through the center of the mounting surface of the thermo electrical cooler and perpendicular to both the first center line and an axis representative of the emitting direction of the laser beam.

  • Patent number: 5577857
    Abstract: End plates are forcibly fixed on the longitudinal end surfaces of pillars such as foundation piles buried in the ground. The upper and lower end plates are butted, and are vertically held by a circumferential recessed groove on the inner surface of an inside ring which is divided in a plurality of parts in the circumferential direction. The inside ring is provided with a conical taper around the outside diameter surface. The conical taper is fastened by an outside ring externally fitted around the outside diameter surface of the inside ring, to join the pillars to each other. This joint structure is simple, and makes it possible to certainly join the pillars at the job site, without any welding. Moreover, there can be provided a tough joint structure against bending.

  • Patent number: 5181042
    Abstract: A planar microstrip array antenna with a beam tilt, which comprises a plurality of pairs of circularly polarized wave radiating elements, the orientation angles of the two radiating elements in each pair being different by a predetermined angle within the plane of the planar antenna. The antenna further comprises a feed line for supplying electric power to the radiating elements. The feed line is provided with a plurality of pairs of terminal feeding portions which diverge corresponding individually to the pairs of circularly polarized wave radiating elements. The paired feeding portions are equal in electrical length. Since the respective orientation angles of the paired radiating elements are different, a phase difference is produced between the radiating elements, thus providing a beam tilt. Since no phase shift portion for producing a phase difference is formed between the paired terminal feeding portions, the configuration of the feed line is simple.

  • Patent number: 5156861
    Abstract: A washing apparatus of a screw for extruder including a casing, support rollers installed in the casing so as to support a screw rotatably, a drive motor for rotating the screw, a water jet assembly having a nozzle and nozzle rotation section, a nozzle inclination motor to incline the water jet assembly relative to the axis direction of the screw. A nozzle hole of the water jet assembly is inclined to face one way relative to the axis of the screw placed on support roller assemblies. The nozzle is rotated eccentrically about the nozzle hole and moved from one end to the other of the screw, changing the nozzle hole direction to the other way relative to the screw at the other end of the screw. The screw is rotated so that an unwashed part of the screw faces the nozzle and is washed. This cycle is repeated until the entire surface of the screw is rotated.
