Abstract: An information processing apparatus, a method, and a non-transitory recording medium. The information processing apparatus, in a case the controller completes an activation after the operation panel completes an activation, detects a connection error between the operation panel and the controller by performing a first determination process of determining whether activation of the controller is completed within a first predetermined period of time after activation of the operation panel is completed and by performing a second determination process of determining whether communication between the operation panel and the controller is established within a second predetermined period of time after completion of the activation of the controller, and in a case the controller completes the activation before the operation panel completes the activation, detects the connection error between the operation panel and the controller by performing the second determination process.

Abstract: A composite material includes: an iron-based alloy layer; an intermediate layer provided on the iron-based alloy layer; and a tungsten-containing layer provided on the intermediate layer, wherein the intermediate layer is composed of pure nickel or is an alloy that contains at least one selected from a group consisting of copper, cobalt, and iron at more than 0 mass % and less than or equal to 71 mass % in total, and that contains nickel at more than or equal to 29 mass % and less than 100 mass %.
