Abstract: A heat pipe includes a tubular member that is a hollow member in which liquid is encapsulated and of which an inner surface is subjected to an oxidation treatment in advance and a movement section that moves the liquid encapsulated and liquefied in the tubular member along a longitudinal direction of the tubular member by means of a capillary phenomenon and of which a surface is subjected to an oxidation treatment in advance.

Abstract: A fixing device includes a belt member that cyclically moves, a pressing unit that comes into contact with the belt member and presses a recording medium moving between the belt member and the pressing unit, and a heat source that includes a base material, a resistance heating element disposed on a surface of the base material along a longitudinal direction of the base material, and an insulator covering the resistance heating element and that comes into contact with the pressing unit via the belt member to heat an inner surface of the belt member, in which the insulator is formed to cover a corner portion of the base material in a direction of movement of the belt member.

Abstract: A breaker includes a fixed piece having a fixed contact, a movable piece having an elastically deformable elastic portion and a movable contact formed at a tip portion of the elastic portion and pushed to contact with the fixed contact, a thermally actuated element deformable according to a temperature change to shift the state of the movable piece from a conductive state to a cut-off state, and a case accommodating the fixed piece, the movable piece, and the thermally actuated element. The movable piece is cantilevered by the case on a base end portion side of the elastic portion, the elastic portion includes a first narrow portion having a smaller width dimension in a short direction perpendicular to a longitudinal direction of the elastic portion than the base end portion, and the first narrow portion has an arc-shaped contour in plan view from a thickness direction of the elastic portion.

Abstract: A breaker 1 includes a fixed piece 2 having a fixed contact 21, a movable piece 4 having an elastically deformable elastic portion 44 and a movable contact 41 formed at a tip portion of the elastic portion 44 and pushed to be in contact with the fixed contact 21, a thermally actuated element 5 deformable in accordance with a temperature change to shift the state of the movable piece 4 from a conductive state to a cut-off state, and a case 10 accommodating the fixed piece 2, the movable piece 4, and the thermally actuated element 5.

Abstract: A pair of destaticizing elements and a resistive element for delaying an electrostatic pulse are provided between a short-circuiting line short-circuiting a plurality of data lines and an upper end portion of each of the data lines. When a short electrostatic pulse is applied to an upper end portion of one data line from the outside, the leading edge of the pulse is made gentle by the resistive element. As a result, the destaticizing element can work well in response to even the short electrostatic pulse.
