A liquid crystal module includes a planar light source device and a liquid crystal panel which are combined together by use of a double-sided adhesive tape (not illustrated). The double-sided adhesive tape is provided on a part of a resin frame, which part is on a light-exit-plane side. A part of the resin frame, which part is not provided with the double-sided adhesive tape, has an uneven surface or has a slit on a surface thereof. In other words, a part of the resin frame, which part corresponds to sections where the planar light source device and the liquid crystal panel are not combined together, has an uneven surface or has a slit on a surface thereof.

A liquid crystal display device (100) of the present invention includes an edge light type backlight unit (10) and a liquid crystal panel (20). The backlight unit (10) includes a light guide plate (2) and a light source (1) that emits light to a light entrance end surface (2a) of the light guide plate (2). An opposite end surface (2b), of the light guide plate (2), which is opposite to the light entrance end surface (2a), is shaped to have one or more triangular shape(s) or one or more rounded shape(s) in a cross section both in a thickness direction of the light guide plate (2) and in a peak luminance direction of light from the light source (1). Light parallel to the peak luminance direction, which light is from the light source (1), is suitably reflected without being scattered by an inclined surface of the opposite end surface (2b).

A billet produced by continuous casting having little central segregation, in particular a billet of high carbon steel produced by continuous casting, and a manufacturing method therefor are provided. In the continuous casting billet, the size of the dendritic equiaxed crystal in a billet central portion is reduced to be not more than 6 mm. For this purpose, electromagnetic stirring is performed so that the inclining angle of the primary dendrite within 10 mm of a billet surface layer is increased to be not less than 10°. Furthermore, the mechanical soft reduction is performed during continuous casting so that the diameter of the center porosity in the billet central portion is reduced to be not more than 4 mm. Thereby, in particular in the manufacturing of the continuous casting billet having a carbon content of not less than 0.6% by mass and a billet size of not more than 160 mm can be provided a billet in which breaking troubles in wire drawing after rolling to a rod are reduced by reducing the central segregation in the billet.

The present invention provides a steel for steel sheets excellent in workability and showing significantly decreased formation of surface defects, and a method of deoxidizing molten steel for the steel for steel sheets which prevents nozzle clogging during continuous-casting the molten steel. That is, the steel for steel sheets excellent in workability, comprises, based on weight, 0.0001 to 0.0030% of C, up to 0.03% of Si, 0.05 to 0.30% of Mn, up to 0.015% of P, 0.001 to 0.015% of S, up to 0.008% of Al, 0.02 to 0.08% of Ti, 0.0005 to 0.0020% of Ca, 0.0005 to 0.01% of N, optionally containing at least one of 0.001 to 0.02 wt % of Nb and 0.0001 to 0.0010 wt % of B, and the balance of Fe and unavoidable impurities. Moreover, the deoxidation method of the steel for steel sheets comprises properly adjusting addition amounts of Ca and Al as deoxidizing agents for the steel having the chemical composition mentioned above so that the chemical composition of the nonmetallic inclusions is controlled to prevent clogging of the casting nozzle.
摘要:
The presence of endotoxin in the outer membrane of cell wall of a Gram-negative bacteria is used to determine bacterial contamination in a biological product. The amount of endotoxin present in a biological product is accurately measured without influence of a limulus reaction-activating substance which causes a false-positive reaction, by a method including the steps of: inactivating the limulus reaction-activating substance, if any, in the biological product, by exposing the biological product to a surfactant at a temperature ranging from the surfactant's freezing point to 50° C.; and measuring the amount of endotoxin present in the biological product, using a limulus reagent.

This invention provides (1) a reagent for endotoxin assay which comprises aprotinin and a limulus amebocyte lysate reagent, (2) a kit for endotoxin assay which comprises the limulus amebocyte lysate reagent and a reagent containing aprotinin, (3) a method for assaying endotoxin in a sample using the limulus amebocyte lysate reagent in which aprotinin is added to the lysate reagent and/or the sample, (4) a method for assaying endotoxin in a serine protease-containing sample using the limulus amebocyte lysate reagent in which the sample is allowed to contact with an aprotinin-immobilized insoluble carrier in advance of endotoxin assay, (5) a carrier for pretreating a serine protease-containing sample on which aprotinin is immobilized, (6) a method for inhibiting factor G activation in which aprotinin is added to the limulus amebocyte lysate reagent and (7) a factor G activation inhibitor which comprises aprotinin as an active ingredient. Endotoxin assay can be effected based on the factor C system reaction, without influences of factor G contained in the limulus amebocyte lysate reagent and/or serine proteases contained in samples.

Disclosed are a reagent for endotoxin-specific assay which comprises an insoluble carrier having immobilized thereon at least an endotoxin-sensitive factor derived from a limulus amebocyte; a kit for endotoxin-specific assay containing said reagent and a substrate for activated factor C or a substrate for clotting enzyme; a method for assaying endotoxin comprising applying a sample solution to said reagent to cause endotoxin in the sample to react with factor C in said reagent and determining a change of a substrate; and a process for preparing said reagent which comprises physically or chemically immobilizing at least an endotoxin-sensitive factor derived from a limulus amebocyte on an insoluble carrier. Endotoxin in a sample, even turbid or colored, can be specifically assayed with ease and rapidness without the influence of a (1.fwdarw.3)-.beta.-glucan.

摘要:
Bacterial endotoxin in an assay sample is determined by an amoebocyte lysate component of horseshoe crab in the presence or absence of a substrate for endotoxin determination by using an assay sample in the liquid state obtained by treating said assay sample with an endotoxin-free acid having a pKa.sup.25.degree. C. value of not more than 3 at a pH of not more than 3; and a kit therefor, a receptacle containing (a) an endotoxin-free acid having a pKa.sup.25.degree. C. value of not more than 3 e.g. perchloric acid, trichloroacetic acid, nitric acid, for treating the assay sample and a receptacle containing (b) an amoebocyte lysate component or horseshoe crab. The acid treatment of the assay sample results in improved accuracy, reliability and reproducibility of the bacterial endotoxin determination.
