IPC: H04L7/00
Filed: 1993-09-10
Abstract: PURPOSE:To eliminate the occurrence of error for decoding by comparing values preceding and following the sample having a maximum synchronous addition value to correct the timing of A/D conversion. CONSTITUTION:A clock deviation detecting circuit 22 uses a result 19 obtained by a synchronous addition circuit 18 to compare the synchronous addition result of a sample M-1 just preceding the sample M having a maximum synchronous addition result and that of a sample M+1 just following it with each other with respect to the correcting direction and the correction value of the phase difference between transmission and reception clocks, and the timing is not corrected when the difference between them is smaller than a set value. When it is larger, the timing is corrected in the accelerating direction; and when the synchronous addition result or the sample M+1 is larger than that of the sample M-1, the timing is corrected in the delaying direction. A timing correction circuit 24 corrects the timing of conversion start of A/D converters 7 and 8 based on a correction value 23. Thus, the phase difference between transmitter and receiver clocks is absorbed, and the receiver performance is improved without increasing the oversampling of A/D converters, and the occurrence of error for decoding is eliminated.

Title: Moving coil type cartridge
Inventor: OOKURA KENICHI
IPC: H04R9/12
Filed: 1983-12-26
Abstract: PURPOSE:To improve the power generating efficiency, to simplify the assembling and to attain stylus replacement by generating a magnetic field with a magnetic pair and placing eccentrically a coil off the center axis of a cuntilever. CONSTITUTION:Since a magnetizing line of magnets 11a, 11b and a center axis of a core 12a are parallel when the cuntilever 2 is not vibrated, the magnetic flux enters coil 8a at a right angle, and goes through the center of the core 12a toward both ends and reaches the S pole of the magnets 11a, 11b from both ends of the magnetic core. No current flows to the coil 8a in this case. When the cuntilever 2 moves upward, since the magnetic gap between the magnets 11a, 11b and the left end of the magnetic core 12a is smaller, a current in response to the change in magnetic flux flows to the coil 8a. Higher magnetic flux is realized by bringing the magnets 11a, 11b close together, and the power generating efficiency is increased. Since the vibrating system and the magnetic system are separated. The MC stereo catridge capable of replacing the stylus is offered.
