An antenna receiving apparatus includes, a first antenna; a second antenna that is synchronized with a frequency band different from the first antenna; a substrate that includes a receiving circuit connected to each of the first antenna and the second antenna; and a back lid that includes a conductor, wherein the conductor is in at least a portion of the back lid. The substrate includes a grounding surface of the first antenna. The substrate and the second antenna are positioned between the first antenna and the back lid. The second antenna is positioned on a side of the substrate opposite of the first antenna, and the second antenna is electrically connected to the conductor of the back lid and grounded.

Antenna receiving apparatus and electronic watch

A timepiece is provided which ensures connection reliability and improves antenna characteristics. This timepiece includes a wristwatch case which houses a timepiece module, and an antenna which is provided on the upper surface of the wristwatch case in a discontinuous annular shape along the circumferential direction of the wristwatch case and electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case. As a result, since the antenna is electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case, the antenna and the timepiece module are unfailingly and favorably connected to each other. Accordingly, the connection reliability of the antenna is ensured and radio waves are favorably received. In addition, the reception performance and the antenna gain are improved, whereby the antenna characteristics are improved.

Timepiece

An antenna device includes a parasitic antenna which is a metal member used as a windshield fixing frame of a wristwatch type electronic device, and a feed antenna which is a conductor. The parasitic antenna has an annular shape, and is disposed close to the feed antenna, and is electromagnetically or capacitively coupled with the feed antenna, and acts as a parasitic antenna to which power is fed from the feed antenna in a non-contact manner, and thereby the feed antenna and the parasitic antenna act in cooperation with each other as a circular polarized antenna for receiving radar waves which are circularly polarized waves having a predetermined wavelength.

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.

Wireless device having low susceptibility to static electricity

A waterproof electronic device includes a waterproof case in which electronic components are embedded and a display which is able to display and which is placed in an opening of the waterproof case in an air tight manner. The waterproof electronic device includes a space for waterproof testing therein and the waterproof electronic device includes a window for waterproof testing at positions (i) corresponding to the space for waterproof testing and (ii) avoiding the display.

Waterproof electronic device

An electronic device includes a case with an opening portion; a cover member arranged in the opening portion so as to close the opening portion; a seal member provided between an outer circumferential surface of the cover member and an inner circumferential surface of the opening portion; a reinforcing portion made of a nonconductive material and provided, in the case, on a portion outside the inner circumferential surface in a direction orthogonal to an axial direction of the opening portion; an antenna; and an electronic component arranged in the case and configured to process a radio wave received by the antenna.

Electronic device

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.

The effect of prolonged skin contact with an electronic apparatus is appropriately suppressed. An electronic apparatusincludes a temperature acquisition unit, a temperature integration unit, and a temperature management unit. The temperature acquisition unitacquires the temperature of the apparatus. The temperature integration unitacquires information (limit time) about the effect on the skin which changes depending on the temperature. The temperature management unitexecutes a preset process, based on the temperature of the apparatus acquired by the temperature acquisition unitand the information about the effect on the skin acquired by the temperature integration unit

Electronic apparatus and operation management method utilizing temperature information to suppress temperature effects caused by apparatus in contact with skin

When external pressure extremely increases, a waterproof vibration membrane tends to be resiliently deformed extremely toward the inside. However, an inward resilient deformation inhibiting member provided on the inner side of the waterproof vibration membrane with a space therebetween inhibits this extreme inward resilient deformation of the waterproof vibration membrane, whereby the waterproof vibration membrane is prevented from being ruptured or plastically deformed. On the other hand, when the internal pressure extremely increases, the waterproof vibration membrane tends to be resiliently deformed extremely toward the outside. However, an outward resilient deformation inhibiting member provided on the outer side of the waterproof vibration membrane with a space therebetween inhibits this extreme outward resilient deformation of the waterproof vibration membrane, whereby the waterproof vibration membrane is prevented from being ruptured or plastically deformed.
