Title: Evaporator for liquefied natural gas
Inventor: ATSUMI TETSUO
IPC: F17C9/02
Filed: 1979-07-17
Abstract: PURPOSE: To vaporize the liquefied natural gas (LNG) effectively without being affected by seasonal changes by bringing the vapor of a heat medium to the saturated pressure at the temperature of a heat source in a process in which an intermediate heat medium is vaporized by heating, liquefied natural gas is vaporized by utilizing its heat of condensation, and then the liquid medium is recycled for reuse.  
     CONSTITUTION: The liquid propane 1 as the intermediate heat medium is vaporized by heating by means of the sea water 19 in an evaporator 3, and then the propane vapor is sent to a condensor 5 where LNG 20 in a heat exchanger 4 is vaporized by the heat of condensation of propane. The condensed propane is directed through the conduit 8 into the evaporator 3, atomized into the heat medium vaporization portion 2 through a nozzle, and then heat-exchanged directly with vaporized propane for vaporization. By keeping the propane vapor at the saturated pressure at the temperature of the sea water as a heat source in this way, the recovery of energy of Rankine system with the intermediate heat medium can be made maximum and LNG can be therefore vaporized effectively.

Abstract: PURPOSE:To prolong the life of an electric power supply circuit, by supplying electric power to a heat element in turn with time lag, when the electric power is applied to the heat element. CONSTITUTION:When a power source switch 5 is turned on, AC voltage is supplied to a controlling circuit 13 through a transformer 6 and a rectifier 12. Therefore, the 1st relay 10 is excited in a moment and AC voltage is supplied to the 1st heat element 21 at the same time when the switch 5 is turned on. While, at the same time, when DC voltage is stored in a capacitor 16 and the set voltage of a voltage regulator diode 15 is obtained, the 2nd relay 11 is excited and AC current flows to the 2nd heat element 22. By such a way, as the circuit 13 supplies electric current to the 1st heat element 21 and the 2nd heat element 22 in turn with time lag, when the switch 5 is turned on, maximum rush current is dispersedly generated, and therefore, the life of an electric power supply circuit is prolonged.

Title: Automatic chemical analyser
Inventor: SHIBUYA HITOSHI
IPC: G01N35/10
Filed: 1985-04-30
Abstract: PURPOSE:To enable the discharge treatment of the residual reagent in a reagent tube and a reagent distribution nozzle without contaminating a reaction container, by providing a discharged solution receiving tray enabled in advance and retraction movement in the moving course of the nozzle distributing a reagent in the reaction container. CONSTITUTION:When the residual reagents in reagent distribution nozzles 2 and reagent tubes 3 are discharged after the analysis of a specimen was finished, a discharged solution receiving tray 7 is positionally set directly under the nozzles by driving a drive means 10. The residual reagents in the nozzles 2 and the tubes 3 are discharged in the tray 7 by the operation of a reagent pump and the discharged reagents are sucked through a tube 9 by a discharge pump to be discharged to the outside. When the discharge amount of the residual reagents is much, the greater part of said reagents can be absorbed by the sponge 8 mounted to the bottom surface of the tray 7 and, therefore, the scattering of the reagents to the circumference can be prevented. By this mechanism, an automatic chemical analyser equipped with function capable of discharging the reagents in the reagent tubes 3 and the reagent distribution nozzles 2 without contaminating a reaction container 5 can be obtained.

Title: Photo coupler
Inventor: HIROSE TSUNEO
IPC: G02B6/28
Filed: 1978-07-26
Abstract: PURPOSE: To make possible in and out of light signal in arbitrary positions of one optical fiber and make multiplied use of one optical fiber by integrally providing a triangular prism or the like on the outside circumferential surface of the optical fiber.  
     CONSTITUTION: When the photo coupler consisting of a cylindrical bar form body 1 and a triangular prism type light transmittable member 6 of a refractive index smaller than that thereof is inserted between optical fibers 3 and 4, the light 5 from the optical fiber 3 does not leak in the outer air of a smaller refractive index even after it has entered the inside of the cylindrical bar form body 1, thus this light propagates in said body. In the case of imputting the light 8 from the outside to the optical fiber 4, the refractive index of the light transmittable member 7 is so selected as to reflect the entire light having entered from the optical fiber 3 and prevent such light from going to the outside and this makes it possible to effectively draw out the light from the way of the optical fiber or adding light.

Abstract: PROBLEM TO BE SOLVED: To guarantee the smooth turning of a door by freely turnably pivotally supporting both ends of a rotary shaft extended along one long side to a main body for the door and providing a rib inside the main body facing the almost center of the rotary shaft. SOLUTION: On the lower end side of the door 6, the rotary shaft 7 is integrally resin-molded in the shape of being along the longitudinal direction. The left and right ends of the rotary shaft 7 are both projected in left and right directions exceeding the width of the door 6 and the tip part is freely turnably pivotally supported by a bearing part 8 integrally formed on the inner surface of the main body 3. The rib 11 is formed on the extension line of the rotary shaft 7 inside the main body 3 facing the almost center of the door 6.
