Abstract: In order to make an operation display device that performs floor setting or maintenance work remotely with a remote controller smaller and better in design, it is equipped with: a faceplate 6 having a display opening 6a; a transmissive plate 7 closing the display opening 6a; an internal sheet metal 9 having a wiring opening 9a and disposed on the back side of the faceplate 6; a liquid crystal display 8 fixed to the front face of the internal sheet metal 9 so as to face the display opening 6a and having a cable 10 passed through the wiring opening 9a to the back side of the internal sheet metal 9; and an infrared receiving device 12 provided on the back side of the internal sheet metal 9 to receive infrared rays 5a from the remote controller 5.

Abstract: An electric power control apparatus, an electric power control method, and an electric power feeding system by which the maximum operating point of a generating element such as a solar battery can be controlled to be maintained, and electric power loss can be avoided. The electric power control apparatus is provided with an electric power path switch unit to which a plurality of generating elements can be connected, and a voltage conversion unit that converts a voltage level which is generated by the generating elements and supplied via the electric power path switch unit. The electric power path switch unit includes a first connection switching function which switches between series connection and parallel connection for the plurality of generating elements, and a second connection switching function which switches between connected and non-connected to an input side of the voltage conversion unit for the generating elements connected in series or parallel.

Abstract: An animal test device for performing a behavior test of a test animal and which can automatically perform optimization of the test includes a cage configuring a living environment of the test animal; a chamber removably attached to the cage; a touch panel provided in the chamber, presenting a problem to the test animal, detecting a response of the test animal, and obtaining response data; a position measurement device that measures a position of the test animal in the cage and the chamber and obtains position data; a data storage unit that stores the response data and the position data as test data; and a problem improvement unit that improves the problem presented by the touch panel, based on the test data.
