Abstract: Provided is an electric device made more convenient by being configured such that the temperature of a wide area in each accommodation section can be individually adjustable. In an electric device, a first refrigerant pipe is provided to a right-side member constituting a side surface of a first accommodation chamber, and a second refrigerant pipe is provided to a left-side member constituting a side surface of a second accommodation chamber. The first refrigerant pipe and the second refrigerant pipe are independent of each other. A regulating valve includes: a first regulating valve provided to the first refrigerant pipe, and a second regulating valve provided to the second refrigerant pipe.

Abstract: Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.

Abstract: A linear extension and retraction mechanism that is mounted in a robot arm mechanism includes: a plurality of first pieces having a flat plate shape which are bendably connected to each other at front and rear end faces; a plurality of second pieces having a groove shape which are bendably connected to each other at front and rear end faces of a bottom part, with the first and second pieces becoming linearly rigid when superposed, and the first and second pieces returning to a bent state when separated from each other; a head section which joins a leading first piece of the plurality of first pieces and a leading second piece of the plurality of second pieces; and a sending-out mechanism section including a plurality of rollers and for firmly superposing the first and second pieces and supporting the first and second pieces movably to front and rear. At least one groove section that extends from front to rear is formed in the surfaces of the first and second pieces that contact the rollers.
