    • In a magnetic tape cassette, a top end portion of a reel urging plate spring for urging a tape reel is subjected to a surface treatment to prevent from a friction. A distance between a couple of flanges of the tape reel is selected to keep a form of the wound magnetic tape, and to prevent the tape running from being disturbed by the increase of a contact resistance of the tape edges to the flanges. Additionally, positioning portions for positioning the magnetic tape cassette relative to a magnetic tape drive device are formed of a differential resin from the resin of the remaining part of the cassette case. Additionally, at least one of both end faces of each guide roller is surface treated so that the end face is not worn through its contact with the cassette half. Further, an information presenting section for displaying variable information is provided at a location other than label areas of the tape cassette.
    • 在磁带盒中,对用于推动磁带卷轴的卷轴推动板簧的顶端部进行表面处理以防止摩擦。 选择磁带卷盘的几个凸缘之间的距离以保持卷绕的磁带的形式,并且为了防止由于带边缘到凸缘的接触电阻的增加而妨碍磁带的运行。 此外,用于将磁带盒相对于磁带驱动装置定位的定位部分由与盒壳体的其余部分的树脂不同的树脂形成。 此外,每个导辊的两个端面中的至少一个被表面处理,使得端面不会通过其与盒半部的接触而磨损。 此外,用于显示可变信息的信息呈现部分设置在除了带盒的标签区域之外的位置处。

    • The present invention relates to cis- and trans-forms of pyrazole derivatives, salts thereof, or agents containing the same, and represented by the general formula (I): wherein G represents a nitrogen containing saturated heterocyclic structure represented by the following formula: These compounds exhibit anti-tumor activity on 5-FU-resistant tumors and effects on P glycoprotein expressing, multiple-drug resistant tumors. An example of a pyrazole derivative which demonstrates 50% inhibition of tumor cell growth is 3-[4-(3-chloro-5-fluorophenyl)-1piperazinyl]-1-[1-(3-chloro-2-pyridyl)-5-methyl-4-pyrazolyl)-1-trans-propene hydrochloride. Synthesis of the compounds represented by formula (I) can be prepared by any one of various routes such as a Mannich reaction, a Wittig reaction, reductive amination or substitution by allylation.

    • Disclosed is an unfired refractory composition comprising a refractory aggregate and a binder for the refractory aggregate, in which the binder comprises a water-soluble or water-dispersible siliceous binder in an amount of 1 to 20% by weight based on the refractory aggregate, a carbonizable organic binder in an amount of 2 to 15% by weight based on the refractory aggregate and a phosphate type hardening agent in an amount of 0.5 to 20% by weight based on the refractory aggregate.This refractory composition is moldable and hardenable at normal temperatures, and has an excellent mechanical strength not only at relatively low temperatures below about 500.degree. C. and high aggregate-firing temperatures but also intermediate temperatures between these low and high temperatures. Accordingly, if this refractory composition is used as a liner for a furnace or the like, break-down of the liner in the intermediate region between the inner surface side and the outer surface side is effectively prevented, resulting in prominent elongation of the life of the liner. Furthermore, this refractory composition has a long pot life in the kneaded state and is excellent in the working property and processability.
    • 公开了一种未烧成的耐火材料组合物,其包含耐火骨料和用于耐火骨料的粘合剂,其中粘合剂包含基于耐火骨料1至20重量%的水溶性或水分散性硅质粘合剂, 相对于耐火骨料,基于耐火骨料和2〜15重量%的可碳化有机粘合剂,相对于耐火骨料为0.5〜20重量%的磷酸盐型硬化剂。 该耐火材料组合物在常温下是可模塑的和可硬化的,并且具有优异的机械强度,不仅在低于约500℃的较低温度和高聚集体焙烧温度下,而且在这些低温和高温之间的中间温度。 因此,如果将该耐火材料组合物用作炉等的衬垫,则有效地防止衬里在内表面侧和外表面侧之间的中间区域的分解,导致显着延长寿命 班轮 此外,该耐火材料组合物在捏合状态下的使用寿命长,加工性和加工性优异。
