    • Disclosed is an improved hinge structure for joining a temple and a front or lens rim together in eyeglasses. It comprises two semicolon-like rotary pieces each having a step-like circular extension integrally connected to its triangular block. The step-like circular extension has a through hole made therein. The semicolon-like rotary pieces are so combined that their step-like circular extensions are laid on each other, with a flat washer sandwiched therebetween. The semicolon-like rotary pieces are joined together by inserting a pivot pin in the through holes of the step-like extensions with another flat washer laid on one side of the so combined rotary pieces, and with the outward-curved resilient washer laid the other side of the so combined rotary pieces. The pivot pin is swaged against the so combined rotary pieces. The triangular blocks of the rotary pieces are to be fixed to the temple and the front or lens rim of the frame.

    • 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.
