Title: Solid electrolyte type fuel cell electrode
Inventor: FUKUI TAKEHISA
IPC: H01M4/86
Filed: 1991-09-24
Abstract: PURPOSE:To suppress the deterioration of electrical characteristic caused by thermal stress between different kind materials by providing a stress concentration portion in an electrode. CONSTITUTION:The electrode 2 on solid electrolyte 1 is formed into an uneven shape having plural number of recess portions 3. The recess portions 3 become stress concentration portions, and stress, applied to the recess portions 3, acts toward the electrolyte 1, being different kind material, so as to produce cracks in a longitudinal direction. The number of the stress concentration portions is decided so considering that thermal stress, applied between different kind materials according to the shape of the stress concentration portion, is well relaxed, and no deterioration of electrode strength and electrical characteristic is induced. Thereby the thermal stress between the electrode and the solid electrolyte or between the electrode and an inter-connector is relaxed, so that the separation of the electrode is reduced and the deterioration of electrical characteristic can be suppressed.

Title: Mechanism for suction/discharge valve for piston type compressor
Inventor: IKEDA ISATO
IPC: F04B39/10
Filed: 1985-12-05
Abstract: PURPOSE:To suppress the vibration of suction and discharge valves and damp down noise resulting from pulsation by forming at least one of the opening areas of a suction port and a discharge port provided on a valve board, non-symmetrically with respect to the center line of the arms of corresponding suction valve and discharge valve. CONSTITUTION:The opening areas of a suction port 9 and a discharge port 10 which are provided on a valve board 4 closely combined with a suction valve 11 and a discharge valve 12, are formed non-symmetrically with respect to the center axis x-x' of arms, or preferably, so that the opening areas on the flowing direction side (y) of a gas cooling medium are the larger. Accordingly, since gas pressure acts on the suction valve 11 and the discharge valve 12 in a lopsided form with respect to the center axis x-x' of these valves, these valves are stably deflected on the lopsided side, which acts so as to also suppress vibration in the regular deflecting direction x-x', thereby, effectively damping down suction and discharge pulsation. Also, by setting the opening areas of the suction port 9 and the discharge port 10 which are formed non-symmetrically, in such a way that the flowing direction side (y) of the gas cooling medium is the larger, the deflecting direction of valves can be stabilized without being against a gas flow.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a shrinkage hole by partially heating around a rises until a die is filled with molten metal, partially and forcedly cooling the position liable to cause the shrinkage cavity after filling up, delaying the solidification of the riser and holding the fluidity. SOLUTION: The riser 42 supplements the molten metal by solidified shrinkage while applying the pressure to a product part 41 through a riser gate part 42a having small cross sectional area. A heating member 50 for heating the riser 42 is constituted by boring a hole 51 from the outer surface to insert a resistant exothermic heater in the inner part. In order to hold the temp. of the riser 42, a refractoriness and heat insulting material layer is arranged on the inner wall surface 42b.

In the double tube, the cooling water is passed through the inner tube and spouted from the tip opening hole and passed through the gap between the inner tube and the outer tube and returned back to the supplying source. By this method, the fluidity of the riser is held to high and the riser is effectively operated and the occurrence of the shrinkage cavity in the cast product can be prevented.
