摘要： A shell-and-tube type heat exchanger of the smallest possible length necessary for heat exchange is disclosed which is capable of obtaining uniform distribution of flow of a shell side fluid and substantially eliminating the structural restriction imposed on the shell side. This shell-and-tube type heat exchanger is provided with one annular conduit furnished with not less than two partitions concurrently serving as an expansion joint for introducing and discharging a shell side fluid and allowing the flow path for said shell side fluid to be separated into an introducing part and a discharging part and which comprises a place having no array of heat-transfer tubes in the flow path for said shell side fluid. It prevents the equipment from necessitating an unnecessary enlargement due to the structural restriction on the shell side and enables the shell side fluid to produce a uniform flow.

摘要： Disclosed is a key sheet having a base sheet equipped with a hard resin plate and a key sheet manufacturing method, wherein a reduction is achieved in the thickness of the base sheet and in the effort and cost for the molding. Further, accurate depressing operation is realized without impairing the outward appearance of the key sheet. The key sheet has a hard base plate having a communicating groove connecting through-holes with each other. The communicating groove has a connecting portion formed so as to be continuous and integral with operating portions formed respectively at the through-holes. Thus, there is no need to form inlets for a rubber-like elastic material respectively corresponding to the through-holes in the mold. As a result, the mold structure can be simplified to thereby achieve a reduction in cost. Further, since the entire front or back surface of the hard base plate is not covered with the rubber-like elastic material, it is possible to achieve an overall reduction in the thickness of the base sheet.
