Abstract: The present invention relates to a method of acrylonitrile-butadiene-styrene (ABS) rubber latex, and the acrylonitrile-butadiene-styrene (ABS) latex is prepared by graft-polymerizing butadiene rubber with the monomers of acrlylonitrile and styrene through emulsion-polymerization, so that the ABS rubber latex of the present invention has high solid content. The method of ABS rubber latex of the present invention comprises the step of emulsion-polymerizing i) polybutadiene rubber latex; ii) aromatic vinyl compound; and iii) vinyl cyanide with the addition of a reactive emulsifier. According to the method of the present invention, the ABS rubber latex has high solid content due to a decrease in the amount of coagulated materials and film, which formed on the rubber latex during polymerization, and an increase in the production volume.

Abstract: A lot dispatching method and system for variably applying the most suitable processing equipment and/or processing condition in a succeeding process of a semiconductor manufacturing process, wherein the succeeding process is influenced by the result of a preceding process. A lot processed by the preceding process is dispatched to the succeeding processing equipment according to a systematic analysis result obtained from a relationship between a process result of the preceding process and an efficiency and the characteristics of a plurality of processing equipment in the succeeding process. A plurality of process conditions for the succeeding process corresponding to the performance of the preceding process is provided. A respective process condition has characteristics that minimize the difference in performance in the succeeding process from a desired or target performance.

Abstract: The present invention relates to a method of acrylonitrile-butadiene-styrene (ABS) rubber latex, and the acrylonitrile-butadiene-styrene (ABS) rubber latex is prepared by graft-polymerizing butadiene rubber with the monomers of acrlylonitrile and styrene through emulsion-polymerization, so that the ABS rubber latex of the present invention has high solid content.

Abstract: A flexible printed circuit film that is capable of preventing a bonded pad from being separated or opened because of a force applied to a bonded part when the flexible printed circuit film is engaged to a printed circuit board. In the film, a first pad is provided at one end of a body to be adhesively connected to a second pad of a first printed circuit board. A third pad is provided at other end of the body to be engaged to a connecter of a second printed circuit board. At least one recess is defined in the body of the flexible printed circuit film. Accordingly, it becomes possible to prevent a contact portion between other pad of the FPC film and the pad of the data circuit board from being separated or opened due to a force applied upon engagement of one pad of the FPC film to the connecter of the timing control board.

Abstract: A cartridge magazine for a firearm comprises a case having a guiding extrusion extending downwardly along at least one wall therein selected from a front wall and a rear wall, a bullet support provided inside the case so as to move up and down and including another guiding extrusion to be movably inserted in the guiding extrusion at a portion selected from a front and a rear portion thereof and having a balance protrusion at another portion thereof, and a spring for elastically and constantly supporting the bullet supporting means. The cartridge serves to smoothly send bullets loaded therein toward a powder chamber of a firearm while maintaining a horizontal level of the bullet support.

Abstract: A cassette loading and unloading device for use in a video cassette recorder ("VCR") comprises a door hinged at the front panel such that it is inwardly swingable, a first and a second side walls, each of which has an upper and a lower guide slots, a cassette holder having at each side surface an upper and a lower slide pins which are respectively fitted in and movable along the upper and the lower guide slots of the side walls, and a first and a second pivot arms tightly fitted on both ends of a shaft rotatably held by the side walls. The first pivot arm has a gear portion at a bottom end. A door opener is rotatably mounted onto the first side wall adjacent to the first pivot arm. The door opener is linked at an upper portion to the door and at a lower portion provided with a cam follower. A lengthwise movable elongate bar has a rack portion engaged with the gear portion of the first pivot arm and a cam provided with a cam surface.

Abstract: A reel table driving device, for a video cassette recorder, comprises a pulley, a driving gear rotated with the pulley, and a first and a second idle gears rotatably fitted on a post fixed to a bracket pivotably mounted to the deck. The first and the idle gears are frictionally coupled to each other through a friction member. The pulley is provided with a boss tightly fitted on a shaft rotatably held by the deck, the boss having a pair of opposite guide groove axially extending. The driving gear has a pair of protrusions inwardly protruding from an inner surface thereof and is fitted onto the boss of the pulley in such a manner that the protrusions are inserted in the respective guide grooves. The driving gear is movable up and down along the guide grooves and rotated together with the pulley by the interaction of the protrusion and the guide groove.

Abstract: A reel table braking device for use in a video cassette recorder having a deck and a reel table rotatably fixed on the deck through a shaft. The reel table braking device comprises a brake assembly mounted on the shaft of the reel table and movable along the shaft between the reel table and the deck, and a slide plate provided with a first and a second urging means having different height from each other. The brake assembly includes a main brake, a sub brake, and a compressive spring fitted on the periphery of the main brake. The main brake has at least one elastic hook and a bottom plate. The bottom plate protrudes from the periphery of the main brake and supports the spring. Furthermore, the sub brake has at least one hook seat corresponding to the elastic hook, is fitted on the main brake in such a way that the hook is inserted in the hook seat, and is biased upwardly by the spring.
