Title: Error correction device of two bit consecutive error and differential coding digital communication equipment using it
Inventor: SHIMAZU MIKIO
IPC: H04L1/00
Filed: 1994-06-01
Abstract: PURPOSE:To suppress the lowering of an effective transmission rate by means of a redandant bit by correcting a two-bit consecutive error generated by differential coding by means of the combination of a one-bit error correcting code and a parity inspection code. CONSTITUTION:An input digital signal Din is transmitted from the transmission part 16 of a transmission system to a transmission route by modulating corresponding to a communication medium. Even when a one-bit error generated on the transmission line becomes the two-bit consecutive error at a difference arithmetic circuit 22, a bit distribution and input circuit 23 sorts an input signal alternately two systems by each bit. Thereby, the two-bit consecutive error becomes the one-bit error at a correction and copying circuit 24 and a parity detection error correction circuit 25 so that the circuit 24 is capable of correction- processing the error and informs the circuit 25 of the piece of error position information at the time of correcting the error. The circuit 25 specifies the one-bit error position by this error position information and the result of parity detection so as to execute correction processing. The redundant bit of parity inspection is one bit and less than bit redundant which is necessary in the one-bit error correction code so that the lowering of the effective transmission rate can be suppressed.

Title: Extrusion molding equipment for ceramic honeycomb structure
Inventor: SHIYARURU BIREERUDEIUUZEEDO
IPC: B28B3/20
Filed: 1988-05-19
Abstract: PURPOSE: To obtain honeycomb structure by using paste with poor plasticity by distributing so that ceramic paste intake holes disposed in network becomes nearly equal to the width of ribbon-shaped paste extruded from these holes. CONSTITUTION: Slits 11 have been disposed along concentric circles 11a and radii 11b of these circles. To give nearly equal width to ribbons of paste that comes out of each hole 10 and extrudes through these slits 11, most of the holes 10 have been disposed at locations off crossings 13 of the slits 11. However, some holes 10a have been disposed on crossings 13 to achieve optimization of distribution. By stipulating distribution of paste intakes in this manner, honeycomb structure with magnetic material can easily be manufactured even when the paste does not have sufficient plasticity.
