An electrical connector includes a socket housing and socket terminals. Each socket terminal includes a front terminal and a rear terminal. The front terminal contacts a plug connector inserted into the socket housing. The front terminal includes front contact-point portion that contacts the plug connector and an elastic piece that supports the front contact-point portion so as to be elastically displaceable. The rear terminal includes a rear contact-point portion and an elastic piece that supports the rear contact-point portion so as to be elastically displaceable. The rear contact-point portion contacts the plug connector after the front contact-point portion has contacted the plug connector. The front contact-point portion and the elastic piece, and the rear contact-point portion and the elastic piece are each formed so as to maintain a plate surface of a flat metal plate.

An oral care instrument, which can maintain a sufficient support strength of a long neck, leaves little residue of a medicant after using, has a low contamination risk from nozzle tip, allows smooth spouting of a medical solution from the beginning, prevents excessive supply of gelatinous or creamy oral-care composition in the case of flowing the composition in a supply channel inside the same, and contributes to the maintenance of the durability of a manufacturing mold. In the aforesaid oral care instrument, which comprises a handle (2), a head (3) and a neck (4), a channel (11) for supplying oral-care composition running within the neck (4) to a nozzle (10) of the head (3) via the handle (2), is formed; and the head (3) is connected in a detachable manner to the neck (4).

A motorcycle includes an ignition switch unit that allows at least starting operation of an engine and unlocking operation of a handlebar by operation of an ignition knob after restriction of turning of the ignition knob by a lock mechanism is canceled when electronic authentication is conducted. An emergency release mechanism is configured to directly or indirectly allow the starting operation of the engine by an emergency release key regardless of the electronic authentication. The emergency release key has a rod-like grip portion, and a magnet key provided to a lateral on a side of an end of the grip portion. A keyhole for the magnet key of the emergency release mechanism is arranged in a direction opposed to an insertion direction of the emergency release key.

A clip includes a pin having at at least a part thereof a noncircular cross-section, and a grommet having an insertion hole into which the pin can be inserted, wherein a part of the grommet is adapted to be expandable by insertion of the pin into the insertion hole. The grommet has slope surfaces provided at an entrance-side hole edge of the insertion hole to lead the pin into the insertion hole when the pin is displaced from a normal position to be in contact with the entrance-side hole edge of the insertion hole.

An implantable electrode array includes an elongated carrier (20) and a plurality of electrodes mounted within the carrier. A actuator adjusts the curvature of the carrier and can be controlled by varying an electric potential applied to the actuator. The actuator is based on an electrochemical cells and may be a conducting polymer based actuator.

A battery (100) includes an electrode body (80) having a positive electrode and a negative electrode and also includes an exterior case (50) formed in a box-like shape having an inner space corresponding to the electrode body (80). An insulation film (10) is provided between the electrode body (80) and the exterior case (50) to isolate them from each other. The insulation film (10) has a bag-like shape surrounding the electrode body (80) and is placed so as not to come into contact with corners (58) of the inner space.

An interior permanent magnet motor includes: a rotor; a stator; and a plurality of permanent magnets respectively inserted into a plurality of magnet insertion holes formed in a rotor core, the rotor core being formed by laminating a plurality of magnetic steel sheets, the magnetic steel sheets including first magnetic steel sheets each not having a magnet stopper in the magnet insertion hole, and second magnetic steel sheets each having magnet stoppers at both end portions of the magnet insertion hole, the rotor core including a laminate of the magnetic steel sheets in a lamination mode in which, when Hn represents a distance between an upper end surface of the second magnetic steel sheet and an upper end surface of the n-th second magnetic steel sheet, a progression of differences of Hn is a geometric progression.

An interdental cleaning instrument is equipped with a base part and a cleaning part. The base part has a shaft part and a grip part. At least the shape of the base part is set in a manner such that a first pressing force required to press a portion spaced 2.5 mm apart from a tip of the cleaning part in 10 mm is 0.3 N or more and 1.4 N or less in a state in which a portion spaced 10 mm apart from the tip of the cleaning part is fixed, and a second pressing force required to press a portion spaced 8.0 mm apart from the tip of the cleaning part in 10 mm is 0.5 N or more and 2.5 N or less in a state in which a portion spaced 35 mm apart from the tip of the cleaning part is fixed.

The endoscope illuminating optical system includes a transparent resin member, and a lighting member which outputs illumination light. The transparent resin member has a through hole in which an image sensor is disposed, a non-through hole in which the lighting member is disposed, an internal optical surface which is formed at an interior of the transparent resin member by the non-through hole, and an outer surface from which the illumination light incident on the transparent resin member via the internal optical surface, is emerged toward an object. The outer surface has a curved-surface area through which the illumination light passes, and the curved-surface area has a boundary with the through hole. In the curved-surface area, a displacement of each point of the curved-surface area from the boundary occurs in a direction away from the object.

In a medical examination sight maintaining videoscope of the present invention, in a state where an examination attachment is attached, it becomes possible to position a scope tip-end section and an object to be examined in a positional relationship in which the scope tip-end section and the object to be examined are straightly aligned with a line of sight of the user. At this time, a monitor is situated at such a position that the user can look straight at the monitor and the line of sight of the user is avoided.

A connector includes a connector main body having a flow path, an insertion body having a tip serving as a connection opening for the flow path, a valve body formed of an elastic body and arranged on the tip of the insertion body to block the connection opening, and a cap which holds the valve body together with the insertion body. The valve body includes a valve main body having slits, an inner projection formed in an annular shape having an outer diameter smaller than the inner diameter of the insertion body and projecting from a bottom face of the valve main body, and a pair of outer projections arranged point-symmetrically to each other with respect to the axis of the inner projection, each of the pair of outer projections projecting from the bottom face on the outer side in the radial direction with respect to the inner projection and being arranged on the inner side of the insertion body.
