  • Patent number: 11543782
    Abstract: 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.

  • Patent number: 9854983
    Abstract: The effect of prolonged skin contact with an electronic apparatus is appropriately suppressed. An electronic apparatus 1 includes a temperature acquisition unit 54, a temperature integration unit 55, and a temperature management unit 56. The temperature acquisition unit 54 acquires the temperature of the apparatus. The temperature integration unit 55 acquires information (limit time) about the effect on the skin which changes depending on the temperature. The temperature management unit 56 executes a preset process, based on the temperature of the apparatus acquired by the temperature acquisition unit 54 and the information about the effect on the skin acquired by the temperature integration unit 55.

  • Patent number: 9510091
    Abstract: 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.
