Title: Wire code-multiplex communication system
Inventor: SUGIYAMA HIROSHI
IPC: H04J13/00
Filed: 1986-04-16
Abstract: PURPOSE:To attain plural communications simultaneously with simple constitution, to reduce the signal deterioration due to external disturbance and to enhance the secrecy by providing a pseudo random number generator of the same constitution to a master station and plural slave station and operating them synchronously via a wired transmission line. CONSTITUTION:The pseudo random number generator 14 of each station is operated synchronously by using a reference clock from a generator 15 of the master station 12. One or two pseudo random number strings of common code to the stations l3a,13b from a generator 14 of each station are sent to a common line modulator 21 and a common line demodulator 23 of each station for the common signal transmission line. The common line signal is sent by a pseudo random number series of each common code prior to the transmission of information to apply the information transmission to the master station 12 and the master station 12 assigns two idle information pseudo random number series other than the common code of the generator 14 for the information transmission of two communication stations. Then each communication station supplies each assigned random series to the information modulator 27 and the demodulator 28 of one's own station from the generator 14 of one's own station to transmit/receive the information signal.

Filed: 1993-03-24
Abstract: PURPOSE:To automatize channel setting and to improve the operability by detecting the channel data by non-reproducing access and selecting/setting the data in a prescribed priority order. CONSTITUTION:When a reproducing instruction is inputted by depressing a key 11 by a user, a CPU 13 operates a CD pickup mechanism 17 through a servo control circuit 15 for the CD mechanism. When program searching is completed, the mechanism 17 makes access to the track area on a target track for a prescribed time in the prohibition state of reproducing a sound and an image and detects the channel data of a disk. When the disk has channel data '2' and '0' in common, the channel data '2' are preferentially set. Then, non- reproducing access is stopped, the pickup is retreated and the natural reproduction of a sound and image is started. Consequently, automatic channel setting is performed and the operability of a CD-G player is improved.

Abstract: PURPOSE:To simplify the circuit constitution and to attain that said constitution is easily made into one chip by connecting transistors for accessing word and bit lines to both output terminals of a memory cell, a pair of bits and a word line and setting freely the slice of a memory array. CONSTITUTION:When the bit lines 2a and 2b selected by a bit slice access are activated to '1', Q7 and Q8 connected to the output terminals 1a and 1b of the memory cell 1 and the word lines 3a and 3b are turned on. Thus the lines 3a and 3b are activated, and stored contents in the cell 1 are read out. Reading at the time of the word slice access is carried out in the same manner through Q5 and Q6 connected to the lines 2a and 2b and the output terminals 1a and 1b, and writing to the cell 4 is similarly executed. Accordingly the bit slice access and word slice access can be freely carried out, and a flip network for re-arranging data is made unnecessary, whereby the circuit constitution can be simplified and making into one chip is facilitated. As a result, an associa tive memory system is scaled down and simplified.
