Title: Dma counter
Inventor: KIM HONG-KI
IPC: G06F13/16
Filed: 1988-06-18
Granted: 1994-04-20
Abstract: The circuit directly counts data and address when input-outptut devices access a memory without helping of a process. The circuit is structured that the data inputted to bus drivers (DR1-DR3) are passed through multiplexers (M1)(M2) and inverters (I1-I8) to be applied to data counters (C1-C4) and data recovery inverters (I9-I16). Inverter outputs (I4-I16) are applied to bus drivers (DR4-DR8) through address counters (C5-C9). The counters (C1-C4),(C5-C9) connects to the ET terminals of higher bit counters (C4)(C9) from RC terminals of the lower bit counters (C1)(C5). The COUNT/ (/LOAD), /BUSAK and /READY signals are applied to clock (CK) and EP terminal of counters (C1-C9) through NOR-Gate (NO1), D flip-flop (F1) and AND-Gate (AG1).

Title: Vaccines and diagnostic assays for haemophilus influenzae
Inventor: DEICH ROBERT A
IPC: G02F1/35
Filed: 1987-12-23
Granted: 1996-12-06
Abstract: Peptides and proteins related to an epitope comprising an outer membrane protein of Haemophilus influenzae. The peptides and proteins can be prepared by methods including novel and improved methods of purification from H. influenzae cultures, and by recombinant DNA and chemical synthetic techniques. Additionally, recombinant vectors containing nucleotide sequences encoding PBOMP-1 related peptides and proteins are also described. Recombinant vectors include plasmid DNA and viral DNA such as human viruses, animal viruses, insect viruses and bacteriophages that direct the expression of PBOMP-1 related peptides and proteins in appropriate host cells. The peptides, proteins and viruses both "live" and "inactivated" are used as immunogens in vaccine formulations to protect against H. influenzae infections. The peptides and proteins are also used as reagents in immunoassays as well as to prepare immunoglobulins for passage immunization. Use of the nucleotide sequences encoding the PBOMP related peptides and proteins in hybridization assays is also described.

Patent KR-0137031-B1 (KR)
Title: Plug-resistant arch-vent for a tire mold
Inventor: ROCKARTS RENE LEON
IPC: B29C33/42
Filed: 1989-02-08
Granted: 1998-04-25
Abstract: A split tire mold having a tread ring in which provision is made for venting air circumferentially across the inner surface of the tread ring so that the air escapes from the parting line of the mold halves, dispenses with widely used, conventional, radially protruding vent stubs. The air is vented through "butterfly-shaped" or "double-wedge-shaped" arch-vents which provide passage for trapped air above each tread block of the tread as it is moved against the inner surface of the tread ring. The shape of the arch-vent passages and the angulation of the wedges is critical to the effectiveness of the arch-vent which forms an arch-vent bridge of cured rubber in a cured tire. The configuration of the bridge allows a cured tire to be easily removed from the mold cavity without leaving a broken-off piece of the rubber bridge to plug the arch-vents. This arch-vent design leaves unobtrusive flat-sided, narrow wedge-shaped pieces of rubber as the arch-vent stubs, tapered in two directions. The arch-vent stubs, when viewed in the radial direction towards the center of the tire, are so unobtrusive as to be cosmetically acceptable in a finished tire. The upper surface of the arch-vent is close to the inner surface of the tread ring and essentially horizontal, while the lower surface of each arch-vent is inclined at an angle in the range from 30 DEG -50 DEG  to the horizontal plane, but in opposite directions. An angle in this range provides surprising strength in the base area of the arch-vent stub so that, upon stripping the tire from the mold, the arch-vent bridge of cured rubber breaks cleanly and reliably at the narrowest and weakest point in the bridge.

Abstract: 본 발명은 반도체 레이저 다이오드에 관한 것으로 선택적 에피택시 방법으로 고효율 및 낮은 문턱 전류를 갖는 매립형 반도체 레이저 다이오드 제조방법에 관한 것이다. 
     종래의 매립형 반도체 레이저 다이오드 제조방법은 기판위에 DH(Double Heterostucture)를 증착하고 선택적 에칭으로 메사 구조를 형성하였다. 
     따라서, 선택적 에칭에 필요한 용액 선택이 어렵고 선택 에칭시 DH 구조시 표면이 산화되어 문턱 전류가 증가되고 소자 특성이 저하되었다. 
     반면, 본 발명은 기판위에 DH 구조를 선택적 성장법으로 메사 구조를 형성하고 DH 구조 맨위에 산화 방지층을 형성하였다. 
     따라서 고효율 및 낮은 문턱 절류를 갖는 레이저 다이오드를 제조할 수 있고 메사 형태를 구성하는 구성 물질 및 구조에 제한을 받지 않아 다양한 매립형 반도체 레이저 다이오드를 제작할 수 있다.

Title: Process for preparing ashes containing amorphous silica
Inventor: LEE DUCK-SOO
IPC: C01B33/18
Filed: 1992-12-08
Granted: 1996-02-13
Abstract: The amorphous SiO2 containing ash is prepared by (A) calcining wood dust ash at 500 deg.C, which is collected by an electric precipitator; (B) extracting alkali components, such as Na2O, K2O and CaO, from the dissolved wood dust ash in a leaching tank; (C) filtering the leachate and, drying and grinding the residue; and (D) combusting again the residue at 450 deg.C to produce a complete ash. The SiO2 containing ash is used to enhance the strength of cement-cured concrete by mixing with cement.

Abstract: In formula(I), (II) and (III), R is C1-C4 alkyl group, C2-C4 alkenyl group, arylalkyl group or aryl group. R2 is phenyl group which can have one or more selected replacement group from H, C1-C4 alkyl group or not fixed position halogen, nitro group and methyl group. R3 is H, methyl group, ethyl group or phenyl group. R4 is methyl group or ethyl group. Methylene maloneite derivatives of formula(III) react with ditiocarbazeite derivatives of formula(II) to get the formula(I) compound under a reaction, which solvent is ethanol, tetrahydrofurane or methylenedicloride. Base used in reaction is alkali metal(C1-C5) alkoxide or 3rd amine. Compound is used as a herbcide.
