Abstract: According to an aspect of the present invention, an antenna system comprises: an antenna panel (1) which has fine irregularities (4) on front and back surfaces thereof, the fine irregularities (4) being formed by blasting so as to regularly reflect service radio waves having longer wavelength than sunlight and scatter sunlight. Further, according to another aspect of the present invention, a method for manufacturing an antenna system in which an antenna panel (1) is manufactured by combining a plurality of constituent parts, comprises the steps of: finishing front and back surface portions of each of the constituent parts so as to thin down the thickness of constituent parts; blasting the front and back surface portions of the constituent parts with abrasive grains; combining the plurality of constituent parts subjected to the blasting step so as to form the antenna panel (1) into a desired shape; and attaching an assistant reflecting mirror (3) to the antenna panel (1) acting as a main reflecting mirror.

Abstract: This disclosure relates to a uniaxial eccentric screw pump. A boss 10a is integrally formed on one end (on the side of a pump casing 8) of the rotor 10, the screw pump 100, and one end of a flexible shaft 9 is inserted in the boss 10a and bonded together with the rotor 10 integrally by means of an adhesive. The flexible shaft 9 is made at least in part from a rod-like member which is extruded from PEEK (polyetheretherketone) which is one of the engineering plastics, into a cylinder. A metal rod 17 is provided in the middle of the flexible shaft in the longitudinal direction, or a metal sleeve is mounted over the outer circumference of the flexible shaft.

Abstract: A process and an apparatus for manufacturing a cast product in which the cavity 2c is defined by a top die 1, a bottom die 2 and a slidable die insert 11 relative to the top die 1 and a pressure is applied to the die insert 11 by a hydraulic cylinder 13 before casting, injecting a molten metal 6 at a pressure higher than that on the die insert 11 to cause the die insert 11 to move rearward, whereby the molten metal 6 is additionally filled in the cavity 2c by an amount corresponding to the shrinkage due to pressurization, and a pressure on the molten metal 6 within the cavity 2c is maintained through the die insert 11 even after the molten metal 6 in the gate 2b has been solidified and the injection pressure has: not been transmitted anymore.

Abstract: A method and an apparatus for sorting chromosomes or cells by utilizing a difference in fluorescent profilepatterns. A linear laser beam having a high beam intensity is formed from several fringe patterns, and fluorescence intensities from local portions of chromosome or cell are measured in real-time. Resolution of chromosome or cell is improved. A type of flowing chromosome or cell which permits the rotational conditions within a range can be sorted accurately and rapidly.

Abstract: A rotor is formed by rotationally cutting a metal mass mounted on a machine tool shaft under computer control, and also its outer periphery is formed with annular grooves by rotational cutting. The rotor is rotated on a shaft while feeding an abrasive to it, while a workpiece set on a stage movable along three perpendicular axes, i.e., X-, Y and Z-axes, urged against the rotor by moving the stage in the Z-axis direction. The surface of the workpiece is polished by causing the stage to be moved in the X-axis direction and reciprocated in the Y-axis direction, the urging pressure being controlled by measuring it with a pressure sensor.

Abstract: A manufacturing method for a defect-free cast product comprises the steps of forming a cavity surrounded by a plurality of dies, charging molten conductive material into the cavity, and applying pressure to the conductive material by pressure means. In the method, additional pressure is selectively applied to the portion of the conductive material which may suffer shrinkage cavities due to delay in solidification, by utilizing the pressure applied by the pressure means and by relatively moving a portion of the dies with respect to the conductive material when the conductive material solidifies and shrinks, whereby shrinkage cavities are prevented. Accordingly, with a cast rotor core obtained by this method, it is possible to prevent shrinkage cavities from occurring in the conductive material and it is also possible to improve the efficiency and torque characteristics of the motor, thereby achieving reductions in the size and weight of the motor.

Abstract: In order to discriminate minute particles such as biological particles or organic polymers, a suspension of minute particles is formed into a particle stream with the individual particles substantially separated from each other, the particle stream is irradiated with a high-intensity light beam, the particle stream irradiated with the high-intensity light beam is formed into droplets, and the particle in each droplet is discriminated in accordance with the intensity of light emited from the particle upon irradiation with the high-intensity light beam. In discriminating the particles, a high-intensity light pulse is used as the high-intensity light beam, and each minute particle is discriminated in accordance with a change in the emitted light intensity over a period of time.

Abstract: The element "lithium" has strong absorption lines near 6707.84 A and 3232.61 A and possesses specific isotope shifts at the respective absorption lines. With the aid of a laser capable of controlling the oscillation spectral width accurately to 0.01 A, the isotopes of this element are separated from each other by irradiating lithium atomic beam with a laser beam tuned to the absorption line of either of the isotopes, .sup.6 Li and .sup.7 Li, for thereby selectively exciting the isotope, ionizing the excited isotope along by irradiation with a laser beam having one photon energy enough to pump it from the excited state to the ionized state and separating the ionized isotope from the un-ionized isotope by means of a mass-filter.

Abstract: An elongated jointing device in the shape of beam body has a substantially H-shape in cross section, the lateral bar portion connecting the pair of parallel vertical portions of the H configuration serving as a distributed fulcrum. A pair of flanged members are positioned with the contact surfaces of their flanges being mated. One of the grooves of the jointing device is fitted onto the mated flanges and pinches them. By inserting at least one wedge into the other groove of the device, the one groove is narrowed thereby pinching the mated flanges and an intimate joint is formed between the two members.
