  • Patent number: 9424557
    Abstract: A communication unit connects an e-mail data transfer protocol to transfer e-mail data item via near-field wireless communications with an external device. A retrieval unit retrieves the e-mail data item transferred from the external device when the protocol is connected. A storage unit stores the retrieved e-mail data item. A control unit causes the external device to transfer the e-mail data item in each indication unit of the indication device thereby to cause the storage unit to store the retrieved e-mail data item, when the protocol is connected, and even when a user does not implement a browsing operation of an e-mail list. The control unit further causes an indication device to indicate the e-mail list of the stored e-mail data item when the user implements the browsing operation.

  • Patent number: 5248133
    Abstract: A plurality of eccentric rotors are rotatably fitted between a fixed base and an output shaft on which an object to be vibrationproofed is mounted, the output shaft being supported movably in 3 to 6 Degree-of-Freedom, magnet spring mechanisms are provided on fitted wall surfaces between the fixed base and the eccentric rotor, a composite vibrationproof adjusting spring is provided between the fixed base and the output shaft, the magnet spring mechanism responding to a fine displacement of the output shaft, and in a case where the output shaft is greatly displaced, the output shaft is braked so as to be restored to a predetermined position by the composite vibrationproof adjusting spring mechanism. The magnet spring mechanism produces a large braking force since a rotational angle is large and a rotational-angle speed is high due to eccentricity of eccentric rotors.
