Abstract: A wireless switch includes a switch body, a push button connected to the switch body in a state of being movable along an approaching/separating direction between a non-operating position and an operating position, a signal output device accommodated in the switch body and configured to output a switch signal in response to a movement of the push button from the non-operating position to the operating position, and a restriction member that restricts the movement of the push button from the non-operating position to the operation position when the push button is located at the non-operating position.

Abstract: The present invention facilitates making electrical connections. In this terminal block, when an electric wire is inserted in a housing, the end of the electric wire pushes in a block part of a movable member, and a contact part of a locking member with the block part interposed therebetween, thereby releasing the locking of a leaf spring moving part by a hook part of the locking member, and the electric wire is secured by the leaf spring moving part, and the degree to which a display part of the movable member moving in conjunction with the block part is visible through a window part changes according to the change in position of the display part.

Abstract: A connector is provided with a locking portion having hook portions extending in the first direction, arranged at intervals around the first direction, and capable of being resilient deformation in a second direction intersecting the first direction and away from the connector main body, and a holding portion having a tubular shape encircling the locking portion around the first direction and having a screw groove portion provided on an inner peripheral surface at an end portion in the first direction and adjacent to a connection portion. The holding portion is moveable between a holding position where the holding portion holds the locking portion locked to a to-be-locked portion of a first mating connector, a hold releasing position where the holding portion releases the holding of the locking portion, and a fitting position where the screw groove portion is fitted to a screw thread portion of a second mating connector.

Abstract: A terminal block includes a display-use moveable member which has a main body portion that can reciprocate in the direction intersecting a terminal connection surface and a contact moveable portion that extends along a guide surface, has a first end portion in an extension direction that is disposed so as to come into contact with a conductor portion in an electric wire passage portion and move in a first direction away from the terminal connection surface, and has a second end portion in the extension direction that is connected to the main body portion, and moves in an array direction in response to movement of the first end portion in the first direction to move the main body portion in a second direction toward the terminal connection surface.

Abstract: A screwless terminal block allows easy insertion and removal of a wire. A housing (2) includes a fixture insertion opening (23) through which a rod-like fixture (6) is inserted to come in contact with a contact pressure spring (4) and deform the spring (4) away from a wire (5). When the fixture (6) is inserted through the fixture insertion opening (23), an acute angle of 45° or less is formed by an axis of the fixture (6) and a straight line connecting a contact point A between the housing (2) and a part of the fixture (6) adjacent to the wire insertion opening (24) and a contact point B between the housing (2) and a part of the fixture (6) adjacent to the spring (4) at a cross-section taken along a plane including the axis of the fixture (6) and parallel to a pressing direction of the spring (4).

Abstract: A composition for effectively preventing or treating peptic ulcers not caused by Helicobacter pylori that does not cause any adverse reaction and thus is highly safe is provided. The present invention relates to a composition for preventing and/or treating peptic ulcers not caused by Helicobacter pylori, which comprises as an active ingredient a browning reaction product of a sugar and a protein.

Abstract: A Coulomb-blockade element includes a silicon layer formed on a substrate through an insulating film. The silicon layer includes a narrow wire portion and first and second electrode portions. The narrow wire portion serves as a conductive island for confining a charge. The first and second electrode portions are formed to be connected to the two ends of the narrow wire portion and are wider than the narrow wire portion. Each of the first and second electrode portions has constrictions on at least one of the upper and lower surfaces thereof, which make a portion near the narrow wire portion thinner than the narrow wire portion.
