Abstract: An accumulated wear amount calculation section calculates a wear amount of a blade edge of a punch and a wear amount of a blade edge of a die when a tool set of the punch and the die has processed a sheet metal once. The accumulated wear amount calculation section calculates an accumulated wear amount of the blade edge of the punch and an accumulated wear amount of the blade edge of the die by accumulating wear amounts of respective times when the tool set has processed the sheet metal multiple times. A tool management information managing section manages a state of the blade edge of each punch and each die by causing a tool management information storage section to store tool management information associating a tool identification code given to each punch and each die with the accumulated wear amounts calculated by the accumulated wear amount calculation section.

Abstract: Provided is a plating catalyst coating agent that offers good plating quality, is excellent in adhesion, and enables thinning of a plating catalyst layer. The plating catalyst coating agent includes a carrier (A) supporting catalytic metal fine particles and a binder (B), the binder (B) includes an aqueous resin emulsion (B1), the carrier (A) has an average particle diameter (D50) of 20 to 90 nm, the catalytic metal fine particles supported on the carrier (A) include palladium, and a content ratio of the binder (B) to the carrier (A) ((B)/(A)) is 0.25 to 0.60.

Abstract: A fuel cell fuel reformer including a gas reactor for producing reformed fuel and an electric heater for heating the gas reactor. An external container includes an inner vacuum chamber, which accommodates the gas reactor and the electric heater, and receiving portions. An electric wire extends through the external container to supply electric power to the electric heater in the inner vacuum chamber. Fluid tubes are received by the receiving portions and extend through the external container. A sealant seals gaps between the fluid tubes and the receiving portions. The gas reactor, the fluid tubes, the external container, and the sealant each have thermal expansion coefficients, with the maximum one of the thermal expansion coefficients being ten-times the minimum one of the thermal expansion coefficients or less.
