摘要： If a determination is made that a signal is not normally detected by the pre-pit-region detection circuit 53, an error signal is obtained from a pulse generator 58 to control the rotations of the disk 50. If a determination is made that a signal is normally detected by the pre-pit-region detection circuit 53 and if the synchronizing signals are not normally detected at predetermined intervals, an error signal is obtained from the wobble signal so that the rotations of the disk 50 are controlled. If a determination is made that synchronizing signals are detected by the pre-pit-region detection circuit 53 at predetermined intervals, an error signal is obtained from clocks synchronized with the reproduced signal generated by the PLL circuit 54 so that rotations of the disk 50 are controlled.

摘要： An audio signal is recorded in a semiconductor memory in a plurality of hierarchical levels, with the lowest level sufficing for reproduction with a certain reduced degree of fidelity. Successfully higher hierarchical levels provide successively greater fidelity when reproduced. When the memory has been determined to have reached maximum capacity, recording continues by overwriting the highest hierarchical level of data currently stored in the memory with lower hierarchical levels of new data. A code is recorded in the memory, indicating the number of hierarchical levels recorded therein, for subsequent reproduction. The audio signal can furthermore be recorded in variable-length frames and reproduced at high speed by reading every N-th frame, N being a positive integer, or by reading only frames having at least a certain minimum length.

摘要： An audio signal is recorded in a semiconductor memory in a plurality of hierarchical levels, with the lowest level being adequate for reproduction with a certain reduced degree of fidelity. Successively higher hierarchial levels provide successively greater fidelity when reproduced. When the memory has been determined to have reached maximum capacity, recording continues by overwriting the highest hierarchical level of data currently stored in the memory with lower hierarchical levels of new data. A code is recorded in the memory, indicating the number of hierarchical levels recorded therein, for subsequent reproduction.

摘要： A conductive connecting structure for electrically connecting first and second electronic parts each having a plurality of connecting terminals arranged at a small pitch is disclosed. A conductive bonding agent is interposed between the plurality of connecting terminals of the first and second electronic parts. The conductive bonding agent is prepared by mixing a plurality of fine connecting particles in an insulating adhesive. Each fine connecting particle is designed such that a fine conductive particle or a fine insulating particle with a plating layer formed on its surface is covered with an insulating layer consisting of a material which is broken upon thermocompression bonding. When the conductive bonding agent is subjected to thermocompression bonding between the connecting terminals of the first and second electronic parts, portions of the fine connecting particles which are urged by the respective fine connecting terminals are broken. However, the insulating layers of the fine connecting particles in the planar direction are not broken and remain as they are. In this conductive connecting structure, even if the ratio of fine connecting particles is increased, and adjacent fine connecting particles are brought into contact with each other, insulating properties can be kept in the planar direction, while conduction is obtained only in the direction of thickness.

摘要： A pulse code modulation (PCM) recording and reproducing apparatus for recording analog signals from N channels which are sampled at a predetermined sampling frequency and converted into samples of a variable number of bits each. The samples of PCM data are assembled into a frame consisting of a specific number of samples and the frames are assembled into a number of blocks of PCM data comprising a specific number of tracks. The number of bits per frame is set to a value equal to the least common multiple of all values of bit quantization numbers which the samples may have such that digital signal sources of varying bit quantization formats may be accomodated by the recording apparatus utilizing a simplified structure.
