摘要： A ceramic blade for a hybrid type gas turbine blade has a dovetail portion, a platform portion formed on the dovetail portion and blade portions formed on the platform portion. The number of the blade portions formed on one platform portion is two or more. The upper surface of the platform portion is shaped into an arc-like form, and the dovetail portion is linearly formed in a tangential direction to a turbine rotation direction. By the utilization of this blade, the hybrid type gas turbine blade can inhibit the leakage of a gas and can be easily manufactured and is excellent in durability.

摘要： A method for manufacturing a ceramic shell-and-tube type heat exchanger having a plurality of heat transfer tubes and tubular plates joined to both the end portions of these heat transfer tubes which has the steps of inserting the heat transfer tubes of sintered tubular ceramics into through-holes of the tubular plates of unsintered plate-like ceramics having a plurality of the through-holes, standing the heat transfer tubes vertically to a floor surface, and then firing them in a condition where the tubular plates are positioned at both the upper and lower end portions of the heat transfer tubes, thereby integrally joining the tubular plates to both the end portions of the plurality of heat transfer tubes by the utilization of a difference between firing shrinkage ratios of both the members, the method having the steps of interposing at least one tubular plate between the tubular plate positioned at the upper end portions and the tubular plate positioned at the lower end portions of the heat transfer tubes, and then firing them to integrally join them. The ceramic shell-and-tube type heat exchanger can be obtained in which the deformation of the heat transfer tubes can be remarkably inhibited and which is free from the deterioration of joining strength due to the deformation of the heat transfer tubes in the firing join step and the occurrence of gas leakage due to a joining failure.

摘要： A mold includes a gate communicating with the entire perimeter of a cavity serving as a space configured to form a molded article. A self-curable molding material with flowability is fed into the perimeter of the cavity through the gate; hence, the mold has a small number of dead ends compared with the case where, for example, the molding material is fed into the cavity through a part of the cavity, preventing the formation of bubbles left in the cavity. The arrangement of a gate and a vent each making an acute angle results in the spontaneous separation of the molded article in the cavity from solidified material portions in the gate and the vent due to shrinkage on curing.

摘要： The present invention relates to a ceramic tube for a high-intensity discharge lamp, comprising a hollow member and a plug member. The hollow member contains a substantially cylindrical body and a closure for closing one end of the body, and the plug member is inserted into an insertion opening formed at the other end of the body. Before the insertion of the plug member, the insertion opening has a tapered portion with a diameter decreasing in the direction from the open end to the inside at least in an area into which the plug member is inserted. After the insertion of the plug member, an outer wall of the plug member is bonded to an inner wall of the insertion opening.
