Abstract: To provide a sealing material sheet for a solar-cell module that has high productivity, and can also suppress unevenness in thickness at the time of integration as a solar-cell module. There is provided a sealing material sheet 1 in which there are two inflection point temperatures that are temperatures only around which a change rate of the linear expansion coefficient locally increases, a first inflection point temperature at a low temperature side of two inflection point temperatures is within a range of 55° C. to 70° C., and a second inflection point at a high temperature side of the inflection point temperatures is within a range of 80° C. to 95° C.

Abstract: A controller for a work machine includes a main board and a PC board. The main board includes a main controller that runs on a built-in work machine operating system, a first activator that activates the main controller when an activation signal for activating the controller is inputted, and an activation commander that outputs an activation-command signal to the PC board when the main controller becomes active. The PC board includes a PC controller that runs on an operating system for PCs, a network terminal, a network controller that outputs the activation signal to the main board when a specific signal for commanding activation is inputted, and a second activator that activates the PC controller when the activation-command signal outputted from the activation commander of the main board is inputted.
