Abstract:
A timepiece component of the present disclosure includes a back cover which is a circumferential rim base that is provided with an attachment hole and attached to a wristwatch case, a terminal attachment member which is arranged in and attached to the attachment hole of the back cover, and charging terminals which are provided in the terminal attachment member and exposed therefrom. The terminal attachment member is made of insulative first resin, the back cover is made of conductive second resin, and a welding layer lies between the terminal attachment member and the back cover. As a result, the circumferential rim base and each terminal are prevented from being electrically connected to each other.
Abstract:
A biological information measuring device provided with a belt which includes at least one electrode detecting a voltage based on biological information in accordance with contact between the at least one electrode and a human body; a supporting member which supports a tank where a predetermined fluid is stored; an attachment which attaches the belt to the supporting member and has a fluid supply portion supplying the fluid to the at least one electrode; and a biological information circuit which measures biological information based on the voltage detected by the at least one electrode.
Abstract:
An electronic device includes a housing and an internal pressure regulator valve. The internal pressure regulator valve includes a valve body of flexible material. The valve body has a valve hole and a hollow. The hollow is continuous with the valve hole and opens into the housing. Through the valve hole, gas is released to outside.
Abstract:
A wireless device includes a circuit board, a communicator disposed on the circuit board, and a casing accommodating the circuit board and the communicator. The casing has a through-hole in a side face. An antenna element is disposed on the exterior of the casing. A feeder extends through the through-hole in the casing and feeds electrical power from the communicator to the antenna element at a predetermined feeding position. A ground terminal extends through the through-hole in the casing and electrically connects the circuit board to the antenna element at a ground position of the antenna element at a predetermined distance from the feeding position.
Abstract:
An acoustic device including: a vibrating film which has waterproofness; a support which is located alongside the vibrating film in a direction and supports the vibrating film; a waterproof which is in contact with the support; an insulating plate which is located on an opposite side of the waterproof to a side where the support is arranged, and which has a first through hole leading to the vibrating film; and a metal plate which is located on an opposite side of the insulating plate to the waterproof, which has a second through hole communicating with or containing the first through hole, and which is fixed in a state pressing the insulating plate along the direction.
