Title: Decoding system for error correction code
Inventor: DOI NOBUKAZU
IPC: H03M13/00
Filed: 1985-04-23
Abstract: PURPOSE:To increase the ability in error correction and to simplify the ability in signal processing and reduce the size of a device by utilizing analog information that a received signal has in addition to syndrome information. CONSTITUTION:The received signal inputted from an input terminal 9 is converted by a binary coding circuit 10 and a ternary coding circuit 11 into a binary and a ternary signal. A nine-bit binary sequence which constitutes an error correction block is parity-checked by a parity checking circuit 13, which outputs a signal '0' to a correcting circuit 15 when there is no parity error or a signal '1' when a parity error is found. A decision circuit 14 receives the ternary signal from the ternary coding circuit 11 and outputs '0' when the signal '0' or '1', or '1' when the signal is an absence bit 'e'. A gate circuit 16 discriminates that an error is correctable or that an error is detected, so its output is used for signal processing. Thus, the ability in error correction is increased and the signal processing is facilitated, so the size of the device is reducible.

Title: Dampening water composition
Inventor: NANBA HIROAKI
IPC: B41N3/08
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To improve printing suitability and aging stability of a water solution and to obtain a printed product having excellent stability by using a carboxymethylcellulose changed by a cellulase as a water solubule polymer compound and specifying viscosity of the solution and substitution degree of a carboxymethyl-containing group. SOLUTION: In the dampening water composition for a lithographic printing plate containing a water soluble polymer compound, as the compound, a carboxymethylcellulose(CMC) changed by a cellulase is used, a viscosity of the solution of 20 wt.% is set to a range of 6 to 500 cps at 25 deg.C, and substitution degree of a carboxymethyl-containing group is set to 0.4 to 2.5. In the case of reducing the viscosity of the CMC in this manner, when an enzymt (cellulase) is used without using a peroxide, its molecular weight is reduced, and the reduction in the viscosity can be expedited. Since it is an enzyme reaction, if it is once deactivated, a problem of a side reaction is eliminated, reaction conditions are moderate, and the CMC can be suppressed in coloring. Thus, stable moistening water composition can be obtained.
