    摘要: In a disc drive for achieving cooling of an electronic part therein, as well as, suppressing transmission of noises generated from a disc clamper, etc., a channel member 18 for introducing an outside air into an inside is disposed between a supporting member 15 and a top-cover 10, within an inside thereof is formed a vortex-like channel, extending from a center to an outer periphery thereof. At the center of the channel member 18 is formed an opening 19 for introducing the outside air into the inside of the disc drive, and on the top-cover 10 are provided plural numbers of openings 20 for taking the outside air into the channel member 18. When an optical disc 6 rotates, pressure generated on an upper surface thereof comes to be negative to the outside air, then the outside air is taken from the openings 20, through the vortex-like channel of the channel member 18 and the opening 19, into the inside of the drive, so as to pass through electronic parts, such as, an optical pickup, etc., thereby cooling them. Noises generated from the disc clamper 17 are attenuated within the vortex-like channel of a long route, which is formed within the channel member 18.

    摘要: A DC power supply capable of obviating undue resetting and malfunction of CPU, immediately after starting the operation of a switching regulator, by inputting sleep signals input asynchronously during a switching cycle of the switching regulator. In the DC power supply adapted to apply a DC voltage to an output terminal by selectively switching between a first voltage from a switching regulator and a second voltage, the switching regulator includes a first switching element and a inductor serially connected between an input terminal for receiving an input voltage and an output terminal, and a second switching element for use in synchronous rectification between the first switching element and the ground, together with a first drive circuit for driving the first switching element, a second drive circuit for driving the second switching element, and a control circuit for controlling the first and second drive circuits. The control circuit is configured to control signals to the first and second drive circuits such that the second switching element is kept turned off until the first switching element is turned on when the operation of the switching regulator is initiated.

    摘要: A switching regulator including two switching elements and a control switching part. The two switching elements perform a switching operation according to a control signal to control an output voltage. One of the two switching elements is larger in ON-resistance and smaller in control electrode capacitance than the other. The control switching part performs PFM control over the one of the two switching elements to output a first predetermined voltage in a first operation mode, performs PWM control over the two switching elements to output a second predetermined voltage higher than the first predetermined voltage in a second operation mode, and switches the first operation mode to the second operation mode by performing the PFM control, changing the first predetermined voltage to the second predetermined voltage, and switching the PFM control to the PWM control after a first predetermined time elapses since start of increase in the output voltage.

    摘要: An anti-reaction valve device is configured to open such that a plunger and a sheet member move away from each other in association with first and second set difference pressures. Two anti-reaction valve devices are provided between two pipes fluidically connected to a hydraulically powered actuator such that directional relationship of connection of primary and secondary ports is reversed between the two anti-reaction valve devices so that a reaction of the actuator is inhibited quickly and reliably. A one-way valve means is positioned between the secondary port and an open and close control chamber within which the plunger and the sheet member are movable into contact with and away from each other and serves to inhibit a back flow of a hydraulic fluid. The one-way valve means is capable of inhibiting the plunger and the sheet member from moving away from each other undesirably, and hence malfunction of the anti-reaction valve devices.
