A sensitivity adjustment device adjusts radio wave sensitivity of an antenna which wirelessly transmits/receives a signal to/from an external device. The sensitivity adjustment device includes: a sensitivity adjuster and an adjuster moving section. The sensitivity adjuster includes (a) a shielding part which shields a radio wave and (b) a penetration part which allows penetration of a radio wave. The adjuster moving section moves the sensitivity adjuster with respect to the antenna in such a way as (a) to change a position of the shielding part and a position of the penetration part with respect to the antenna, and (b) to adjust a covered area of the antenna covered with the sensitivity adjuster, so as to adjust the radio wave sensitivity of the antenna.

Sensitivity adjustment device and radio wave communication device

A switch device of the present invention includes a cylindrical member attached to a through hole of a wristwatch case, an operation member having an operation shaft section inserted into the cylindrical member and an operation head section provided at the outer end of the operation member, a cushioning member attached to the operation head section of the operation member to cover the operation head section, and an exterior member fixed to the operation head section to cover the cushioning member and from which a plurality of portions of the cushioning member project outwardly. Therefore, when the exterior member receives an external impact, the impact can be mitigated by the cushioning member projecting outwardly from the exterior member. As a result, the operation member and the cylindrical member can be prevented from being damaged by the external impact, whereby the impact resistance can be increased.

A band, a wristwatch with the band and a method of making the band are described. The band includes a strip-like body with a series of holes provided therein along a length thereof for adjusting an effective length thereof. The body includes a band-shaped support layer of woven or knit fabric of bundles of one or more kinds of fibers, the fibers being selected from a group including carbon fibers, glass fibers, aramid fibers and boron fibers. The body also includes a first resin layer adhering closely to one surface of the support layer, and a second resin layer adhering closely to the other surface of the support layer. The fibers of the support layer extend at a predetermined angle to longitudinal and transverse directions of the body.

A watchband attaching structure includes paired projections provided on a case-side end part of a watchband and having coaxial first through-holes, and an intermediate part provided at a predetermined position on an outer circumference of a wristwatch case, placed between the projections, and having a second through-hole coaxial to the first holes. A diameter of the second hole is smaller than that of the first hole. Headed first and second screw members inserted into center holes of first and second tubular members are introduced into the first holes of the projections and the second hole of the intermediate part from both sides thereof. Male threads and female threads of the distal ends of the first and second members are connected to each other in the second hole while the heads thereof with the first and second tubular members are arranged in the first holes of the projections.

The present invention relates to a connecting adapter for connecting an earphone with a body part of a writs type of music player. In a casing , an earphone jack , and a circuit board having a continuity with the earphone jack are provided. A connection terminal having a continuity with an earphone connector of the body art is provided so as to penetrate the inside and the outside of the casing and have a continuity with the circuit board . On the outer surface of the casing , a fixed hook for engaging with a concavity of the body part and a movable hook for engaging with a concavity of the body part , which is incorporated so as to be rotatable and to be biased toward the body part , are provided.

Adapter for external connection and electronic apparatus

A band which can be changed easily and speedily comprises a first band member to which a case is attached detachably, a second band member disposed to overlap on the first band member, and a loop into which the second band member and a right end portion of the first band member are inserted to overlap each other to secure the right end portion of the first band member to the second band member detachably. By pulling out the right end portion of the first band member from the loop, the right end portion of the first band member can be detached from the second band member. By inserting the right end portion of the first band member and the second band member into the loop to overlap each other, the right end portion of the first band member can be attached to the second band member.
