Title: Coding method
Inventor: YAMAUCHI TOSHITANE
IPC: H03M13/00
Filed: 1979-09-04
Abstract: PURPOSE:To increase the coding efficiency at the inferior transmission circuit and also securing high reliability, by converting the information word of the CRC coding method into the matrix and then giving the parity check code to the matrix. CONSTITUTION:For example, the undetected error rate PB is reduced by adding the internal coding of the information length R bit to the (n, R, 4) CRC (Cyclic Redundancy Check) coding of the code length (n) bit, the information R bit and the intercode distance 4. Then the R bit has constitution (R=aXb) of the row (a) and the column (b) each, and the data obtained by calculating the parity of each row direction of the row (a) and the column (b-1) up to the (b-1) column, i.e., the composite coding method having the horizontal parity code is adopted for the column (b) data of the final column. The figure shows the matrix in which the information word of (k) bit is set for the row (a) and the column (b) each, and the (r) bit is the CRC check bit, i.e., the redundant bit which means the residual obtained by dividing the equation aXb=k by the grown polynomial g(x).

Abstract: PURPOSE:To enable a high printing position accuracy to be maintained even with some play between a hammer and bearings holding the hammer, by a method wherein a means allowing slide at right angles to a projecting direction is provided on at least one abutting surface between a type element and the hammer. CONSTITUTION:A coating layer of Teflon, molybdenum disulfide, or the like having a low frictional coefficient is formed on an abutting part of a hammer top part 1a against a type element 2. The coating layer 1b reduces a frictional force to a large extent, thus resulting in the longitudinal rigidity of the type element 2 larger than the frictional force and the occurrence of slide between the type element 2 and the hammer top part 1a. Therefore, the type element 2 depends only on the crosswise motion of the hammer top part 1a and reaches a platen at a proper printing position 2 independently of the motion of the hammer top part 1a. In this manner, a printing position accuracy can be maintained high.
