Abstract: A humidifier includes: a water supply portion (supply pipe, supply part, and nozzle) to supply water; a flat-shaped diffusing member that is provided below the water supply portion, and diffuses the water supplied from the water supply portion in a plane direction and in a thickness direction; a humidifying member that is fixed and has a top surface in contact with and the diffusing member, and evaporates the water supplied from the diffusing member via the top surface; and fixing parts that apply pressure to at least a part of a portion of contact between the diffusing member and the humidifying member.

Abstract: A probe pin includes a coil spring, a first plunger, and second and third plungers. The second and third plungers respectively are independently operable and include a main body and first and second elastic pieces that extend from the main body in the same direction to each other. The first plunger is inserted between the first and second elastic pieces each of the second and third plungers.

Abstract: A probe pin includes a coil spring, a first plunger, a first end of which is inserted from a first end of the coil spring into the coil spring and a second end of which is exposed to outside of the coil spring, and a second plunger, a first end of which is inserted from a second end of the coil spring into the coil spring to be in contact with the first end of the first plunger and a second end of which is exposed to the outside of the coil spring. The second plunger includes at least one elastic arm extending from the second end of the second plunger, and a touch portion is provided at a leading end of the elastic arm and displaceable in a direction intersecting an axial center direction when pressing force in the axial center direction is applied to the touch portion.

Abstract: A contact element (25) (electroformed product) is produced by electroforming. The contact element (25) has a surface on which an insulating film (28) having been formed by use of a dry film resist or the like is provided. In a process of producing the contact element (25), the insulating film (28) is provided after a step of producing the contact element 25. This makes it possible to provide electroformed components configured so that respective electroformed products (contact terminals) are arranged at narrow pitches while maintaining electrical insulation of the electroformed products from each other.

Abstract: In a probe pin including a coil spring, and first and second plungers, when the first and second plungers are respectively inserted from both ends of the coil spring toward an inside thereof, the first and second plungers are disposed in a reciprocable manner along an axis center of the coil spring while slide contact surfaces thereof are in slide contact with each other, and the first and second plungers are formed so that the coil spring can be held between a body portion of the first plunger and a body portion of the second plunger. The first and second plungers are formed so that the first and second plungers are close to each other and a contact area where the slide contact surface of the first plunger is in contact with the slide contact surface of the second plunger is tilted with respect to the axis center.

Abstract: A probe pin has a coil spring having a first end and a second end, a first plunger having a major portion, and a first elastic extension and a second elastic extension that from the major portion in the same direction, and a second plunger forcedly inserted between the first and the second elastic extensions. The first and the second plungers have electric conductivity. The first and the second plungers are inserted from the first and second ends of the coil spring, respectively, so that the first and the second elastic extensions of the first plunger hold the second plunger with the first elastic extension making a forced contact with a surface of the second plunger to form thereat an electric connection between the first and the second plungers.

Abstract: A connecting mechanism having a male contact and a female contact, each of the male and female contacts having a first surface including at least in part a flat surface portion defined therein, a second surface opposing the first surface, and a contact surface extending between the first surface and the second surface. The contact surface is designed so that, when the first contact and the second contact are electrically connected with each other, the contact surfaces of the first contact and the second contact make a surface contact therebetween that inclines with respect to the flat surface portions of the first and second contacts in a cross section that crosses the first surface, the second surface, and the contact surface.
