    摘要: To provide an optical disk drive having an enhanced replaying capability in case of an abnormality occurring in various kinds of synchronization of the optical disk drive or in replay of a defective sector. A frame synchronization counter value address translation decoder, low order ID address translation decoder, adder/subtracter, high order ID address translation decoder, and adder are used to translate information read from an optical disk medium into an absolute storage address in a storage medium, and thus data that is highly replayed can be stored in the storage medium.

    摘要: A control device for a toroidal type continuously variable transmission is provided which controls the speed ratio of the toroidal type continuously variable transmission depending upon a current throttle opening and a current vehicle speed. This transmission includes an input disc and an output disc having mutually facing toroidal faces with oil films formed thereon, and a friction roller disposed between the input disc and the output disc to effect power transmission therebetween such that the speed ratio is changed by controlling an angle of inclination of the friction roller. The control device of the invention determines a temperature of the oil films, and sets at least one of an upper limit and a lower limit of the angle of inclination based on the determined temperature of the oil films, so that the speed ratio is controlled within the range of the angle of inclination set by the control device.

    摘要: In an optical pickup, an optical guide member is provided in an optical path of light from a light source, and has a plurality of inclined surfaces inclined with respect to a light beam emitted from the light source. A light-receiving element is provided for receiving light and for converting the received light into an electrical signal. The optical guide member and the light-receiving element are contained in a packaging member. The light beam from the light source is reflected by the plurality of inclined surfaces of the optical guide member, and then are directed to a recording medium. The reflected light from the recording medium is directed to the light-receiving element. At least one of dry air and inert gas such as nitrogen gas is charged in the interior of the packaging member at a pressure of 0.5 atm to 1.5 atm, thereby preventing the optical characteristics from being degraded.

    摘要: A bus interface system has a bus interface, a common memory, a local bus, and a memory controller for use in a memory control. The memory controller has a buffer and is connected to the local bus. The bus interface has a burst disassembling control circuit which disassembles burst transfer data into one or a plurality of block transfers and one or a plurality of one-word transfers, which are supplied to the memory controller so that when the bus interface receives all requested data received from the common memory during a read access, the bus interface adds information on a destination device, connected to a system bus, to all the requested data and sends all the requested data with that information to the destination device via the system bus.
