Abstract: The packaging paper is manufactured by attaching crosswisely flat yarns of polypropylene, polyethylene, polyester or nylon to paper as a reinforcement layer. The crosswisely attached flat yarns maintain a high strength for the packaging paper, prevent curling of paper, and improve the packaging performance.

Title: Header error control decoder using 5 byte syndrom generator
Inventor: CHON JONG-AM
IPC: H03M13/00
Filed: 1993-05-18
Granted: 1997-02-21
Abstract: The 6 bytes shift register(21) modifies single bit error of the cell header and the 5 bytes syndrome generator(22) generates the syndrome signal of the 5 successive bytes per byte clock. The multiplexor(23) multiplexes the syndrome load and the syndrome register(24) stores the output signal temporarily, then outputs it. The exclusive OR calculus means(25) updates the syndrome signal and the syndrome decoder(28) generates the judgement signal of the syndrome calculation. The syndrome pattern decoder(27) decodes 8 syndrome pattern which single bit error generates in the first byte among 5 bytes data returning step by step. The error modifier(26) amends the error, if the error signal is single bit error, single bit error decoder sets single bit error signal to one.

Abstract: 본 발명은 프레임과 화상담지 부재와,  화상담지 부재에 작용하는 프로세스 수단과 프로세스 카트리지를 파지하는 파지부를 포함하고,  화상 형성장치에 장착 가능한 프로세스 카트리지를 제공한다.   파지부는,  프로세스 카트리지를 화상 형성장치에 장착할 때에 프로세스 카트리지와 본체상의 부재 사이의 결합에 의해 발생되는 보다 큰 장착저항이 프레임에 부세되는 위치의 방향으로 오프셋 되도록 상기 프레임 위에 형성된다(제 49도).
