    Abstract: A coated metal sheet provided with a coating on at least one surface thereof. The coating contains a polyester resin as a main component and a ?-hydroxyalkylamide compound as a curing agent. Since the coating has an elongation of not less than 200% under test conditions of 90° C., the coated metal sheet has excellent can-making workability without metal exposure even if the coated metal sheet is subjected to severe working such as drawing and ironing. Also disclosed is a drawn-ironed can formed of the coated metal sheet.

  • Publication number: 20210395977
    Abstract: A sensibility meter detects biometric information relating to an operator corresponding to an output from a target appliance, and determines a comfort level of the operator based on the biometric information. A first control unit determines a second target value relating to the output based on a difference between a first target value relating to the comfort level and the comfort level. A second control unit determines a control input to the target appliance based on a difference between the second target value and the output. A ? setting unit performs weighting corresponding to an operation level of the operator, for an operation input to the target appliance by the operator, and for the control input. An adder adds the weighted operation input and control input, and inputs the resultant to the target appliance.
