Title: Water supply circuit for cup type automatic vending machine
Inventor: UMEMOTO KATSUHISA
IPC: G07F13/06
Filed: 1990-11-24
Abstract: PURPOSE:To prevent an insanitary state from occurring due to the stagnation of water of normal temperature by supplying the water of normal temperature to an ice making machine on a first pipeline, and eliminating foreign matters by a filter via a second pipeline. CONSTITUTION:The water level of the water of normal temperature in a reservoir tub 8 can be kept within the upper and lower limits, and the water runs to the ice making machine 9 by head between the ice making machine 9 and the reservoir tub 8 passing the first pipeline 23. Such flow can be stopped transiently by switching a three way valve 28. When drink water is sold, or the water level in a hot water tub 10 arrives at the lower limit, ice in the reservoir part 18 of the ice making machine 9 is molten, and is added on the water of normal temperature. Thereby, the three way valve 28 is switched, and a pump 25 is started up, and the water flows in the hot water tub 10 and the cooling tube of a cooling machine 11 passing most of the pipeline 23, a bypass pipeline 41, pipelines 27, 29. Thereby, the foreign matters can be eliminated by the filter 24 provided at the pipeline 27, and the propagation of the foreign matters due to the stagnation of the water of normal temperature can be prevented from occurring, which prevents odor from occurring.

IPC: G02B6/44
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To stably produce an optical fiber cord having a cross sectional shape of a rectangular shape over a long length. SOLUTION: The viscosity of a resin liquid at the time of coating thereof is specified to 6000 to 8000 cPs at the time of producing the optical fiber cord 4 by placing plural pieces of tension members 2, 2... longitudinally along an optical fiber 1, feeding this optical fiber into a die and applying the resin liquid constituting a coating layer 3 on the fiber in this die, then curing the resin liquid. The adjustment of the viscosity may be executed by the kind, compsn., temp., etc., of the resin liquid. A method of changing the temp. of the resin liquid is usually adopted. If the viscosity of the resin liquid at the time of coating is below 6000 cPs, the cross sectional shape of the resulted optical fiber cord is made elliptic, providing inconvenience.  When the viscosity exceeds 8000 cPs, the inclusion of air bubbles into the resin liquid and the flow defect thereof occur, providing inconvenience.

Filed: 1993-12-20
Abstract: PURPOSE:To change the composition of a refrigerant circulating through a freezing cycle and to improve efficiency by a method wherein when the amount of a refrigerant dissolved in lubricating oil is varied with the change of the temperature and the pressure of lubricating oil. CONSTITUTION:High-temperature high-pressure refrigerant steam compressed by a compressor 1 releases heat in a condenser 2 and condensed and liquefied. Thereafter, the refrigerant steam is reduced in pressure and expanded by a throttling device 3 and produces a gas-liquid two-phase refrigerant. The refrigerant absorbs heat in a vaporizer 4 for vaporization and gasification and turns into refrigerant steam and is sucked in the compressor 1 again. In this case, lubricating oil during a freezing cycle having characteristics differing with the change of temperature and pressure from those of the refrigerant is used. In this case, the temperature of lubricating oil in the compressor 1 is controlled by a lubricating oil temperature regulator 5. This constitution varies generation capacity by changing the composition of lubricating refrigerant and improves efficiency.
