摘要： A differential code (DPCM) transmission system for an audio signal, in case higher frequency components thereof are dominant, every another samples of the input signal are alternately into two groups, in each of which differential coding effected, so as to maintain a dynamic range in higher frequency range; when a near instantaneously compressed DPCM signal is transmitted, coding errors caused by the compression are corrected by varying the difference between samples in response to the comparison between a locally decoded signal and the original signal; when the frequency components exceeding one fourth of the sampling frequency are contained in the input signal, successive 3 MSB's having a pattern "1, 0, 1" or "0, 1, 0" are corrected into "1, 1, 1" or "0, 0, 0" respectively; and in case 2 symbols of a tertiary code converted from 3 bits of a binary code are transmitted and restored, peripheral bit arrangement of a matrix having rows consisting of the first symbols of the converted tertiary codes and columns consisting of the second symbols thereof are allotted such as Gray codes are obtained, while an inner 2.times.2 matrix of a 4.times. 4 matrix formed by inserting a new threshold level between two threshold levels provided for detecting the tertiary code is allocated with bits relating to bits arranged at adjacent positions, so as to reduce the bit error rate of the restored binary code.

摘要： A signal transmission system for high definition television that can handle a second television signal which is superior in quality to a first television signal such as an NTSC (National Television System Committee) television signal. The transmitting end of the system transmits a first television signal including a video signal, audio signals, etc., through a main transmission line, as well as a third television signal including a high definition components obtained as the difference between the second and the first television signal through an auxiliary transmission line. The receiving end of the system receives and synthesizes the first television signal transmitted through the main transmission line and the third television signal transmitted through the auxiliary transmission line to produce the second television signal.

摘要： An automatic cassette tape recorder stop apparatus which can drive a plurality of magnetic tapes simultaneously or individually and includes a sensor for each of the tapes; and a lock release block which receives the load applied to each sensor, rotates a trigger lever through a conversion lever, and actuates a cam gear, a lock release plate and a lock plate. The automatic stop apparatus further includes a load-receiving resilient member for each sensor which does not allow the load on the sensor to be transmitted to the trigger lever while the tape is running but allows the load to be transmitted to the trigger lever for its rotation when the tape has been wound to the end.

摘要： A cassette tape player comprises a reproduction head mounted on a subchassis, and a nonprogram section detection circuit for searching a nonprogram section provided between two adjacent programs recorded on a magnetic tape while the magnetic tape is driven to travel at a fast speed. When a fast forward lever or a fast rewind lever is locked under the condition where a playback lever is locked and the subchassis is held at a predetermined position, a switch mounted on the subchassis is switched on to power supply the nonprogram section detection circuit. That is, the cassette tape player is placed in a nonprogram section detection mode when both the playback lever, and the fast forward lever or the fast rewind lever are locked. Upon detecting the nonprogram section, a plunger is activated to unlock the fast forward lever or the fast rewind lever to return the cassette tape player to a normal playback mode.

摘要： A route guidance apparatus comprises a guiding device for, every time a turning point for which guidance is to be provided existing on a route for reaching a destination is approached, providing travel guidance for that turning point by at least a voice generated from a voice generating device. In particular, when the turning point for which guidance is to be provided is included in a traffic circle and the route turns from the traffic circle to an exit road toward an outer side thereof at the turning point, the guiding device provides travel guidance specifying how many ahead the exit road to be taken is among exit roads toward the outer side of the traffic circle. As a result, travel guidance with which a user can exit from the traffic circle through a correct exit.
