Abstract: One pair of resonant electrodes is formed in a loop shape or a spiral shape in a substrate stacking direction symmetrically to each other. This allows a longitudinal space in substrate to be reduced. A first capacitor having an electrode connected to the grounding conductor layer, an electrode connected to an open-end side of the resonant electrode, and a dielectric layer is provided. A second capacitor having an electrode connected to the grounding conductor layer, an electrode connected to an open-end side of the resonant electrode, and a dielectric layer is also provided. This results in having a desired characteristic even if a length of the resonant electrode is short.

Abstract: This invention is a method for manufacturing a high-frequency module device. A high-frequency circuit unit (2) in which first to third unit wiring layers (5) to (7), each having a capacitor (12) or the like at a part, are stacked and formed on flattened one surface of a dummy board (30) so that a third pattern wiring is exposed from a connection surface (2a) of an uppermost layer is mounted on a mounting surface (3a) of a base board (3) where an input/output terminal part (18) is exposed, in such a manner that the third pattern wiring and the input/output terminal part are connected with each other, and after that, the dummy board is removed. A high-frequency module device is thus manufactured.

Abstract: There is provided a semiconductor device with enhanced reliability having a heat sink mounting a plurality of semiconductor chips, a plurality of inner leads connected electrically to the semiconductor chips, a molding body for resin molding the plurality of semiconductor chips and the plurality of inner leads, a plurality of wires for providing electrical connections between the respective electrodes of the semiconductor chips and the inner leads corresponding thereto, and wide outer leads connecting to the inner leads and exposed outside the molding body. A plurality of slits are formed in the respective portions of the outer leads located outside the molding body to extend lengthwise in directions in which the outer leads are extracted. This achieves a reduction in lead stress which is placed on the outer leads by thermal stress or the like after the mounting of a MOSFET and thereby enhances the reliability of the MOSFET.

Abstract: An additional information signal is recorded at a predetermined position in a series of sectors in which image data coded by an intra-frame or intra-field coding method are recorded. The additional information signal is extracted and a pickup driving circuit is controlled. Thus, only the intra-frame or intra-field coded image data sets can be reproduced. A transfer rate is recorded as the additional information, so that the image data can be stably reproduced. It is possible to predict the position of the first sector to be the next reproduced of the series of sectors in which the intra-frame coded image data are recorded, on the basis of the position of the first one of the series of sectors in which intra-frame coded image data are recorded and the position of the first one of a previous series of sectors in which the intra-frame coded image data are recorded.

Abstract: When data is recorded to a recording medium having a sector structure, the data is recorded with synchronization signals (frame marks) placed at a constant interval for use during data reproduction. When the data is then reproduced from this recording medium, these frame marks are detected to demodulate the data based on the detected signals.

Abstract: An apparatus for intermittently recording or reproducing a time-varying image includes a buffer interposed between a compression-encoder unit and a recording processor or between a decoder and a reproducing processor, a buffer controller for monitoring the quantity of effective information stored in the buffer, and a system controller for interrupting and restarting the operation of the recording processor or the reproducing processor according to the quantity of the effective information stored in the buffer. During recording, a plurality of consecutive image frames is separated into a plurality of groups, in each of which the image frames are intraframe or interframe compression-coded to digital image information. The total quantity of compression-coded digital image information is limited to a value smaller than a first predetermined value. The digital image information contained in each group is partitioned in units of a second predetermined value smaller than the first predetermined value.

Abstract: In an audio and video recording apparatus, a video signal is separated into a luminance signal and a chrominance signal. The luminance signal is separated into low frequency and high frequency components. The high frequency component signal is subjected to balanced modulation to be thereafter band-compressed by interleaving the lower side band thereof to the low frequency component. The chrominance signal is processed to be a line sequential color difference signal. An audio signal is sampled and encoded. The luminance signal, the color difference signal and the audio signal are subjected to time-axis compression multiplexing in one frame with a synchronizing signal, address signals and control signals. The multiplex signal is recorded on a recording medium.
