Abstract: The present invention provides an optical disk recording apparatus which can reduce consumption of a power calibration area and prevent recording quality from being deteriorated by appropriately renewing an optimum recording power, and a method for setting an optimum recording power in an optical disk recording apparatus. The optical disk recording apparatus stores an optimum recording power which is obtained by performing trial writing in the power calibration area and an amplitude level Am of a reproduction signal, and in case of additional recording in a write-once optical disk, obtains an amplitude level Ar by reproducing again the area in which the trial writing is previously performed, and compares the stored amplitude level Am with the amplitude level Ar. When the amplitude level is lowered, an optimum recording power is renewed by performing trial writing again, and when the amplitude level is not lowered, the additional recording is performed using the stored optimum recording power.

Abstract: A data broadcasting station transmits a multiplexed signal in which multimedia data encoded in a prescribed coding system are at least multiplexed in a broadcasting form. A file manager stores the multimedia data received by a tuner and decoded by a decoder in a storage device while creating management information therefor and registering it in a table. A browser requests of the file manager multimedia data to be referred to, and lets it be displayed on a monitor. The file manager increments/decrements a retention coefficient on the basis of a frequency of reference to the multimedia, and determines whether or not to delete each multimedia data stored in the storage device. Thus provided is a terminal device which can effectively utilize the capacity of the storage device without deleting multimedia data frequently referred to by the user.

Abstract: In an optical disc apparatus, a semiconductor SLD driving device is mounted on an optical pickup in order to realize a high speed switching of drive current for a semiconductor laser diode (SLD), necessary for recording data. The SLD is placed. within 5 cm from the SLD driving device. The driving device becomes a heat source due to driving current of the SLD, and increases a temperature of the optical pickup.

The SLD driving device is mounted to the optical pickup, and this driving device handles N pieces of input signals for setting semiconductor laser power and N pieces of switch-timing-input-signals for selecting respective input signals.

Abstract: A moving picture encoding decoding processing apparatus for detecting a motion vector by forming the image data of the search area for motion vector with small capacity of memory rapidly and efficiently. A moving picture encoding decoding processing apparatus detects the macroblock number by a macroblock counter. A macroblock recognition part recognizes whether the search area for the motion vector of the macroblock is extending over the frame image area or not based on the position of the macroblock in the frame image. A macroblock recognition part generates an extrapolation pattern signal which indicates the pattern of the extrapolation for the inputted macroblock. If the whole search area is within the frame area, image data formed on a frame memory 2 are used. If the search area extends beyond the frame area, image data formed on a prediction memory 3 are used. A control unit 1 includes an image data transmission means.

Abstract: The invention presents a magnetic recording and reproducing apparatus capable of reducing the size and preventing external force from propagating directly to the internal mechanism. To achieve the object, a main arm 26 and a sub-arm 29 are constituted so as not to intersect with a photo detector 31 always during rotating operation within a plane including the photo detector 31, and the dimension can be hence reduced in the width direction of the apparatus, and moreover as the wall thickness of MIC-SW 46 is reduced, the upper end of the MIC-SW 46 is held by a back plate 48, so that the dimension of the apparatus can be reduced also in the depth direction, and further a cassette holder 13 is locked by a damper 42 to prevent effects from outside when a sub-chassis 19 moves from unloading position to loading position.

Abstract: A resin-molded semiconductor device includes: signal leads; a die pad with a central portion elevated above a peripheral portion thereof; support leads, each including a raised portion higher in level than the other portions; and DB paste for use in die bonding. All of these members are encapsulated within a resin encapsulant. The lower part of each of these signal leads protrudes downward out of the resin encapsulant and functions as an external electrode. Each of the support leads is provided with two bent portions to cushion the deforming force. By forming a half-blanked portion in the die pad, the central portion is elevated above the peripheral portion, thus preventing the semiconductor chip from being hampered by the support leads. Accordingly, the size of the semiconductor chip mounted can be selected from a broader range and the humidity resistance of the device can also be improved.

Abstract: In case two slots among the communications slots 0 through 7 in a time-division-multiplexed frame is used and the receiving field level of a communications signal from the first base station 1 has dropped below a predetermined reference value while data transmission/reception is in progress, retrieval of an announcement signal from another base station in the remaining idle slots is started. A link channel is established to a candidate base station and processing from TCH synchronization to CONNECT reception is performed while communications with the first base station 1 is maintained. On receiving CONNECT (speed enable signal), communications with the first base station is halted and data transmission/reception to/from the candidate base station is started to perform voice or data communications and complete a handover. Thus, it is provided a handover control method whereby the mute time in a handover during communications is minimized to continue conversation seamlessly.
