Title: Device for forming solid shape
Inventor: OKADA GENSUKE
IPC: G01B11/245
Filed: 1984-04-17
Abstract: PURPOSE:To manufacture a solid shape of the same shape as an object by having a means to measure the sectional shape of the surface of the object from the relation of the locus shape of a light image obtainable from a two-dimensional image pickup means and of slitted light irradiating means and two-dimensional image pickup means. CONSTITUTION:A light irradiating device 2 is fixed to a rack 8 and the rack 8 is fixed to a ball nut, so by rotating a ball screw shaft 5 with a motor, the rack 8 can be driven vertically against an axis Z step by step by the height of the thickness DELTAh of a slitted light. A light image locus is then found each diameter DELTAh of the slitted light 2' from the extreme bottom end Z0 to the extreme top end Zm of a model 1 which is an object on the plane formed by a slitted light, i.e., on the plane of X-Y axis, and shape data Xi, Yi are found each change of the diameter DELTAh of a slitted light. These data are then inputted into an NC laser cutting machine and from the thickness DELTAh of a thin sheet, a same form sheet with the shape data is produced and by overlapping those in order, a solid shape same as an object can be manufactured.

Title: Calibration method of concentration measuring apparatus in salt-making plant
IPC: G01N29/02
Filed: 1992-03-31
Abstract: PURPOSE:To simply perform a calibration operation by a method wherein a mother liquor from which salt is precipitated is used, the velocity of sound in a calibration liquid is measured by using a concentration measuring apparatus and the concentration measuring apparatus is calibrated. CONSTITUTION:When a calibration operation is performed, a warmwater pipe (c) is used as a calibration-liquid supply pipe. A calibration liquid in the state of a mother liquor is supplied to the warm-water pipe (c); a sample tank 5 is filled with the calibration liquid via a motor valve 3, a sampling pipe (d) and a sampling pump 4; the calibration liquid is measured; the calibration operation is performed on the basis of the velocity of sound which is displayed on a display part 11. Even when the precipitation amount of salt is changed at this time due to, e.g. a change in the temperature of the calibration liquid, the velocity of sound of the calibration liquid becomes nearly definite. Consequently, the value of the velocity of sound which is displayed on the display part 11 can be evaluated absolutely. In addition, the calibration operation itself can be handled simply, and the calibration operation can be performed easily even when many measuring apparatuses are calibrated.

Title: Optical fiber cable
Inventor: HAYASHI YOSHIAKI
IPC: G02B6/44
Filed: 1988-03-29
Abstract: PURPOSE:To prevent deterioration of transmitting function of an optical fiber cable against the lapse of time by filling optical fibers comprising a metal halide as a raw material in a metallic protective tube having an oxidized film on an inside surface. CONSTITUTION:A metal component of a metallic protective tube 11 is isolated from a metal halide in optical fibers 13 and moisture by forming an oxidized film 12 on an inside surface of the metallic protective tube 11. Thereby, a chemical reaction between the metal component of the metallic protective tube 11 and metal halide in the optical fiber 13 is retarded, and degeneration of a surface layer and crystal boundary of the optical fiber 13 is prevented. Since Scattering or absorption of infrared rays is not increased, so decrease of transmittance of the optical fiber is also prevented. Aluminium or iron group metal in addition to conventionally useful stainless steel may be useful for the metallic protective tube so far as it is suited to form a stable oxide film on the inside of a tube made thereof. By this constitution, deterioration of transmission function of an optical fiber cable against the lapse of time is prevented.

Abstract: PURPOSE:To form a small amount of fine particles and to obtain polymer particles having narrow particle diameter distribution, by subjecting a vinyl monomer to suspension polymerization in an aqueous medium in the presence of a specific compound and adding a water-soluble metallic salt to the polymerization system at a specific conversion ratio of polymerization. CONSTITUTION:In subjecting a vinyl monomer (e.g. styrene, vinyltoluene, etc.) to suspension polymerization in an aqueous medium usually in the presence of a radical initiator such as benzoyl peroxide, etc., preferably 0.2-0.5pt.wt. based on 100pts.wt. monomer of a slightly soluble inorganic salt (e.g. calcium phosphate, etc.) as a suspension stabilizer, preferably 0.002-0.02pt.wt. alkylnaphthalenesulfonate as an auxiliary for the suspension stabilizer and 0.001-0.01pt.wt. nonionic surface active agent (e.g. dodecylbenzenesulfonate, etc.) as a growth promotor for particle diameter are added to the polymerization system at <55% conversion ratio of polymerization and polymerization is carried out. While the conversion ratio of polymerization shows 55-75%, a water- soluble metallic salt (e.g. Na2SO4, etc.) exhibiting neutrality in an aqueous medium is added to the polymerization system.

Title: Inverter unit
Inventor: YAMANAKA YUKIO
IPC: H05B41/24
Filed: 1990-03-27
Abstract: PURPOSE:To suppress distortion of input current by feeding back a resonance current to an input AC power supply at every cycle of high frequency and shaping thus fed back resonance current through a filter or the like. CONSTITUTION:Upon throwing in a power supply, a transistor(TR)Tr2 is turned ON and the voltage across the transistor goes Low. Consequently, a starting circuit stops and the TRTr2 is turned OFF upon elapse of a predetermined time thus conducting a diode(DI)D1. Furthermore, a TRTr1 is turned ON and current flows through the TRTr1 when the current of a DID1 goes zero. When the core of an inductor L1 is saturated, time variation of the collector current of the TRTr1 goes infinite. When the collector current of the TRTr1 reaches (hfe) times of the base current, the TRTr1 is turned OFF. Subsequently, the DID1 is conducted and current flows through the DID1. Consequently, voltage across the TRTr2 goes zero and biased forwardly. After the oscillating current flowing through the DID2 goes zero, current flows from a capacitor C3.
