Title: Fuel cell power generation system
Inventor: TAKEMOTO TOSHIAKI
IPC: H01M8/06
Filed: 1984-03-30
Abstract: PURPOSE:To increase the density of hydrogen storage so as to reduce the whole size of a fuel storage device by using a hydrogen-absorbing alloy for hydrogen storage in the device. CONSTITUTION:A fuel storage device 2 is constituted of a gas tank 16, a hydrogen-absorbing alloy 17 installed in the gas tank 16, and the like. The hydrogen- absorbing alloy 17 is connected to a part of a cell temperature controller 11, or the cooling water discharge side of a cooler 9 and the suction side of a water supply pump 14, so that the temperature of the hydrogen-absorbing alloy 17 is controlled by warmed cooling water. When a fuel temperature detector 27 detects that the temperature of a fuel cell 1 has increased to a given level during starting, valves 25 and 18 are gradually opened and warm water is introduced to the heat exchange part of the fuel storage device 2 from the outlet of the fuel- cooling system. The thus introduced warm water warms the hydrogen-absorbing alloy 17 to produce hydrogen gas. The thus produced hydrogen is then led to the anode.

Title: Can cap rotating device
Inventor: KAWAGUCHI AKIRA
IPC: B21D43/14
Filed: 1990-03-12
Abstract: PURPOSE:To facilitate the smooth discharge of can caps in the selective discharge positions for discharging defective can caps, etc., by providing an injection port to inject a positive pressure gas to the side of a vent path to be exclusively used in a common vent path so as to position in the communicating place with this vent to be exclusively used existing in the selective discharge position for the can caps. CONSTITUTION:The attraction force in a can cap mounting stage 18 existing in the selective discharge position is temporarily weakened and the can cap K can be easily and selectively discharged if the positive pressure gas is temporarily supplied to the injection port if the can cap K on the mounting stag 18 is required to be discharged. Since the can cap stage 18 is communicated with the common vent path 31 by the respectively separate vent paths 40 to be exclusively used, the pressure on the can cap mounting stage existing in the other position is prevented from being changed by the pressure of the positive pressure gas from the above-mentioned injection port. The attraction of the can cap in an ordinary manner is executed according to the rotating position of a turn table 12 on the other can cap mounting stage. The exact positioning of the can cap is executed by this attraction if the constitution of a V-groove, etc., for guiding the can cap is previously provided on the mounting stage. The discharge of the can caps in the position for discharging the defective can caps, etc., is facilitated in this way.

Title: Ionization chamber type radiation detector
Inventor: KONAGAI CHIKARA
IPC: H01J47/02
Filed: 1978-05-24
Abstract: PURPOSE:To make the manufacture of the detector easy by making electrode supports by metal material and supporting signal electrodes to the electrode supports by way of insulators. CONSTITUTION:Electrode supports 9a are made of metal material of easy grooving to facilitate provision of multichannels in proximity. In addition, both end edges of the signal electrodes 6a are secured by being sandwiched to one of the long end edges of two rectargular strip form insulators 11. The other of the long end edges are fitted in the grooves 12 of the electrode supports 9a. A bias electrode 5a is connected and fixed directly into the grooves 12 of the electrode supports 9a. This eliminates the need for providing a terminal for application of bias voltage to each sheet of the bias electrodes. If the length of the insulators which holds the signal electrodes from both sides is suitably selected or if grooves crossing these are provided, the countermeasure for prevention of creeping discharge may be readily taken. In this way, the manufacture of the detector may be made easy.
