Abstract: The formation of a bellows made up of a stack of a predetermined number of ring-convolutions and having an intermediate plate supported within said stack is achieved by supplying several thin metal rings, each having inner and outer edges. A pair of these metal rings are positioned in contiguous relationship and their adjacent inside edges are welded together to form a ring-convolution. This process is repeated until a sufficient number of ring-convolutions are made to eventually make the desired bellows. Before these separate ring-convolutions are fused to each other, an intermediate plate and a support ring are made. The intermediate plate is a disc of metal that is sized smaller than the inside diameter of the rings and is secured to the support ring. The support ring is then positioned between two formed ring-convolutions in contiguous relationship and the three abutting outside edges are welded to each other to form a support plate convolution.

Abstract: A ceramic heater, heat exchange unit, and warm water washing toilet seat are provided having excellent temperature rise characteristics and a shortened heating time to reach a predetermined water temperature. A ceramic heater having a pattern watt density of 50 W/cm2 and above, and a surface watt density of 25 W/cm2 and above has a short start-up time and excellent temperature rise characteristics. Further, the thickness of a core is reduced to between 0.5 mm and 1.9 mm (circular tube thickness is between 1 mm and 2.4 mm), which enables efficient transfer of heat from the ceramic heater to water flowing in the circular tube. Accordingly, a gap between a heat exchanger and the ceramic heater is not necessarily narrowed, such that air bubbles are not likely trapped and breakage of the ceramic heater by thermal shock can be suppressed.
