  • Patent number: 10073504
    Abstract: The present invention provides a storage subsystem capable of preventing abnormal temperature rise within the subsystem and realizing an efficient cooling effect. Therefore, the storage subsystem has two or more controllers having two or more temperature sensors, and each controller determines a provisional rotational speed based on the value of the temperature sensors. One controller out of the multiple controllers operates as the master controller, and the other controllers (slave controllers) transmit a provisional rotational speed determined in its own system to the master controller. The master controller determines a greater value of the provisional rotational speed information received from the slave controllers and the provisional rotational speed determined in its own system as the final rotational speed of the fan.

  • Patent number: 8760987
    Abstract: An optical disc drive device has a metallic exterior casing and an internal unit to be housed in the exterior casing. The internal unit further includes an optical pickup unit for performing recording or reproduction of information signals on an optical disc, and a printed wiring substrate on which a connector electrically connected to the optical pickup unit and serving for transmission and reception of electrical signals from and to external electronic equipment is mounted. The exterior casing has an opening for allowing the connector to be exposed outside, the printed wiring substrate has a ground pattern formed to surround the connector, and a fringe portion of the opening of the exterior casing and the ground pattern are in electrical contact with each other. Thus, radiation noise from around wiring lines contained in the optical disc drive device or the like is reduced.
