Abstract: A funnel structure for a cathode ray tube satisfies following equations 0.33≦Rhmaj/Rhmaj≦0.51, Rhmaj=Hmaj/Umaj, Rmaj=amaj/bmaj, wherein a length of a major axis evaluation line as an imaginary line connecting the major axis outer end of a sealing surface, at which a panel meets a funnel, with the major axis outer end of a TOR (top of round), at which a body portion meets a yoke portion, is defined as bmaj; a length from a point on the major axis evaluation line, which has a maximum vertical line length to the outer surface of the funnel, to the major axis outer end of the sealing surface is defined as amaj; a maximum length of the vertical line is defined as Hmaj; and ½ of a major axis length of an effective surface of the panel is defined as Umaj.

Abstract: A funnel structure of a CRT in which provided that a deflection angle is 110° or more, a length of an outer surface evaluation line formed by connecting a TOR outer surface end where the funnel yoke portion and the funnel body portion meet and a neck seal outer surface end where the funnel yoke portion and the neck portion meet by a straight line is ‘a’ and a length of a straight line from the outer surface evaluation line where a vertical distance between the funnel yoke portion outer surface and the outer surface evaluation line is maximized, to the neck seal outer surface end is ‘b’, a formula of 0.20≦b/a≦0.40 is satisfied, so that a sensitivity of a deflection yoke is improved and a beam shadow neck margin of the electron beam can be satisfied.

Abstract: The present invention relates to anti-adhesion barriers which prevents an adhesion between tissues at an operated legion and have various shapes, comprising sodium carboxymethyl cellulose (NaCMC) and gellan gum in 1:(0.1˜10) of weight ratio.

Abstract: Disclosed is a color cathode-ray tube which has an optimum funnel structure so that it has a slim tube structure while reducing stress caused by its internal vacuum pressure. The color cathode-ray tube satisfies a relation of 0.12×L′<S<0.27×L′ where “L” represents a length from a seal line, where a panel and a funnel are sealably coupled together, to a yoke line of the funnel in an axial direction of the tube, “L′” represents ½ of the length of the seal line, “A” represents ½ of a seal stress adjustment line formed by connecting points spaced apart from the seal line by a distance of “L×0.67” toward the yoke portion, and “S” represents a difference between “L′” and “A”.

Abstract: Implosion protection band for color cathode ray tube having a panel with a wedge ratio of 1.1˜1.8 and a substantially flat outer surface, wherein the implosion protection band is strapped around an outer circumference of the panel to satisfy a condition of 0.2≦UW/LW≦0.5, where the UW denotes an upper band width and the LW denotes a lower band width with reference to an extension line from an inside surface of the panel at a center thereof, thereby reducing a maximum stress on the panel by approx. 5%˜7% compared to the same in the related art and improve an implosion proof characteristics.

Abstract: Disclosed is a structure of panel in flat-type CRT (Cathode Ray Tube), which is capable of securing a stable vacuum intensity by applying a sufficient tension to a face part of a panel using a straight safety band, and of effectively reducing an advance of crack and a scatter of fragments due to an external shock by optimizing the relationship among an MMH (Mold Match Height), a CFT (Center Face Thickness) and an OAH (Overall Height), which are design factors. The structure of panel in flat-type CRT (Cathode Ray Tube) includes a face part having a flat outer surface and an inner surface of a fixed curvature, and a skirt part extending from an edge of the face part to a rear portion.

Abstract: Disclosed is the use of biosurfactants as biological control products. In particular, rhamnolipid biosurfactants produced by Pseudomonas spp. were demonstrated to rapidly kill zoospores by rupturing the plasma membrane of three representative zoosporic plant pathogenic microorganisms: Pythium aphanidernatum, Plasmopara lactucae-radicis, and Phytophthora capsici.
