摘要： PROBLEM TO BE SOLVED: To provide a vacuum valve with a high reliability which is improved in a property for refrigeration and allows a large current passage by forming a flowing path at least in a movable shaft or a fixed shaft, and prevents a refrigerating fluid in the flowing path from leaking to a vacuum container. SOLUTION: The fixed shaft or the movable shaft is formed from an end shaft with an end on the inside of the vacuum container and a bottom on the outside of the vacuum container, and a bottom shaft joined to the bottom of the end shaft on the outside of the vacuum container. A flowing path, which enters through an entrance at the bottom, goes to the end, is folded, and returns to an exit at the bottom, is formed in the end shaft. A path of the refrigerating fluid for flowing in and out, which is joined to the entrance and the exit opened at the bottom of the end shaft, is formed in the bottom shaft.

摘要： PROBLEM TO BE SOLVED: To enhance corrosion resistance, antifreezing performance and cooling efficiency while sustaining insulation performance by employing an aqueous solution containing a specified vol.% of water soluble alcohol as a medium for cooling a power converter comprising power elements. SOLUTION: An aqueous solution being used as a medium for cooling electric parts of an inverter, e.g. semiconductor elements and resistors, is composed of pure water, water soluble alcohol and a rust preventing agent. Content of the water soluble alcohol is set at 60 vol.% or below in order to be exempted from regulations on hazardous materials and a saturated or unsaturated 15-21C higher aliphatic carboxylate of an alkali metal of organic carbonate is employed as the rust preventing agent. When aluminum is employed as the material of heat sink for a power converter, high corrosion resistance can be attained if the content of alcohol effective as an alcohol solution is 10% or above. When corrosion resistance, antifreezing performance and cooling efficiency are taken into account, the content of water soluble alcohol is preferably set at 20-30%.

摘要： PURPOSE:To control a steam generation quantity at a prescribed value, and operate a power generation system optimally by controlling a power generation quantity while adjusting flow rate of cooling water flowed into a fuel cell cooling system according to power generation output detected by a power generation output detecting means. CONSTITUTION:Power generation output of a fuel cell body 1 is detected by means of a power generation output detector 10, and when its detected value is given to a flow rate control device 11, opening of a flow rate adjusting valve 9 is found in the device 11 according to the power generation output, and opening control signals are given to the valve 9. Thereby, the opening of the valve 9 is adjusted by means of the opening control signals, and flow rate of cooling water flowed into a fuel cell cooling system IC of the body 1 is controlled. In this case, the flow rate of cooling water is controlled, so that the cooling water becomes the optimal temperature to the body 1, and also that two phase flow having a prescribed quality of vapor dryness of steam can be obtained from the fuel cell cooling system. Here, the steam recovered as high quality exhaust heat is used, for example, in an absorption type refrigerating machine 7. Furthermore, even if a cooler is not arranged in a passage on the inlet port side of the cooling system IC, the cooling water having the optimal temperature can be supplied to the body 1.

摘要： PURPOSE:To enable detection of temperature of an element surface without decreasing a contact area between the cooling body and the element surface, by a method wherein a thermocouple or a conductive wire is inserted in a rectangular pipe, and the rectangular pipe is bent and further wound in spiral form. CONSTITUTION:When a rectangular pipe 12 of metal with high thermal conduction, such as copper or aluminium, is bent together with a forward path 13 and a return path 14 being circulation path for a cooling medium into spiral form from the center portion, a thermocouple wire 17 is inserted between the forward path 13 and the return path 14. A heat sensitive member 18 is disposed at position of an element to be detected, and a cooling body 1 is formed by such a contact that a gap is not produced between adjacent pipes. And then a contact surface with the element is slightly processed in both surfaces to accomplish the surface finishing.

摘要： PROBLEM TO BE SOLVED: To obtain a power conversion system in which noise accompanying the driving is reduced through a common noise reducer, even when a plurality of power converters are connected in parallel, and the size can be reduced easily. SOLUTION: A DC voltage is applied from an AC input line via an insulating transformer 9 and a rectifier circuit 10 to a positive side output line P1 and a negative side output line N1. The DC voltage is divided by capacitors Cp, Cn, by fixing the intermediate series joint 11 to the earth potential. Consequently, the positive side output line P1 can supply a positive constant voltage at all times with respect to ground potential, and the negative side output line N1 can supply a negative constant voltage constantly. When transistors Tr1, Tr2 are turned on/off by an amplifier 7, a noise compensation current i flows through the series joint 11 of Cp, Cn between the grounded AC input line and the ground. Joints of a noise reducer are concentrated at the prestage of each power converter through such an operation to more the noise reducer shared.

摘要： PURPOSE:To enhance the reliability by applying a pressure higher than the atmospheric pressure to a storage tank, thereby eliminating the decrease in the coolant in the upper part of a thyristor bulb when a pump is stopped. CONSTITUTION:A storage tank 13 is formed in a completely sealed structure, a compression chamber 20 of the upper part and a compressor 21 are piped to apply pressure higher than the atmospheric pressure. When a pump 16 becomes abnormal or is stopped, coolant in thyristor bulbs 10-40 is applied with the pressure higher than the atmospheric pressure. Accordingly, it does not fall. Accordingly, insulation breakdown due to the damage or discharge of the tubes 12A, 12B can be prevented.
