Abstract: Disclosed are a papermaking method of preparing a paper having a reinforced strength wherein a polymer latex is added to a paper stock in an amount of from 2.5 to 30 % by weight. The polymer latex is prepared by neutralizing a seed polymer with an acid or a salt or by quaternizing it with a quaternizing agent. The surfaces of the emulsion grains are highly densely cationated. The seed polymer is formed by adding a monomer as represented by the following formula (I) or a mixture of the monomer (I) and copolymerizable ethylenic unsaturated monomer(s) (II) to a seed latex of a carboxyl-modified synthetic rubber latex or synthetic resin emulsion and polymerizing them: <CHEM>  R1 represents H or CH3;  R2 represents an alkylene group having from 2 to 5 carbon atoms; R3 and R4 each represent H or an alkyl group having from 1 to 5 carbon atoms;  A represents   - @-O- or   -@-NH-; and R1, R3 and R4 and so selected that the monomer is hardly soluble or insoluble in water.   The paper has a noticeably improved paper-strength.

Abstract: The thermoplastic resin compsn. a having chemical resistance comprises : 60-99 wt.pts of ABS resin; 40-1 wt.pts of polyolefin resin; 20-100 wt.pts (w.r.t. 100 wt.pts of the polyolefin resin) of thermoplastic styrene copolymer. The polyolefin resin comprises 100-90 wt.pts of polyethylene and 90-10 wt.pts of polypropylene. Pref. the polyethylene resin is a homopolymer or copolymer having below 10g/min of the melt flow rate, 30000-50000 of number ave. Mw and 3-15 of the molecular weight distribution. Pref. the polypropylene resin is a crystal polypropylene homopolymer having below 8g/min of the melt flow rate.

Abstract: 본 발명은 디지탈신호의 통신 및 전송에서 데이터의 동기를 검출하기위한 시스템에 관한 것으로, 송신측에서 에러정정을 위한 소정의 코딩과 에러발생의 확산을 위한 인터리빙을 수행한 전송데이터를 수신하여 변조된 신호를 소정의 주파수로 복조하는 수단과, 복조된 전송데이터에 대해 송신측에서 수행한 인터리빙과정의 역과정에 해당하는 디인터리빙과정을 수행하는 수단과, 디인터리빙된 데이터의 동기가 맞지 않으면 데이터의 디인터리빙순서를 가변시켜 디인터리빙된 데이터의  동기가 맞을 때까지 반복적으로 디인터리빙순서를 가변시키는 수단을 구비하여, 송신측에서 전송데이터에 별도의 동기신호를 삽입하지 않아도 수신측에서 데이터의 동기가 자동으로 검출된다.

Abstract: 본 발명은, 광정보처리장치의 소형화를 도모하기 위하여, 앞쪽초점면과 뒤쪽초점면간의 거리를 단축한 푸리에 변환렌즈 또는 렌즈길이를 단축한 푸리에 변환렌즈 및 푸리에 변환광학계의 도중에 반환점을 형성한 광정보처리장치를 제공하는 것을 목적으로 한 것으로서, 그 구성에 있어서, 물체쪽으로부터 차례로 전방그룹 G1이 정의파워를 가지고 중간그룹 G2가 부의파워를 가지고 후방그룹 G3이 정의파워를 가지도록 광학계를 배치함으로써, 앞쪽초점면 H와 뒤쪽초점면 Ha사이의 거리를 초점거리의 2배보다 짧게 할 수 있다. 따라서, 상기 푸리에 변환렌즈를 사용함으로써 광로길이가 단축되어, 광정보처리장치의 소형화를 실현할 수 있는 것을 특징으로 한다.
