A liquid crystal display element having an improved response speed by using a liquid crystal compound having a high K, while neither improving nor deteriorating all the characteristics as a liquid crystal display element. The liquid crystal display elementof the present invention has a first substrate, a second substrate', and a liquid crystal composition layerinterposed between the first substrateand the second substrate&#x2032;, wherein at least one of the first substrateand the second substrate&#x2032; has an electrode that controls the liquid crystal composition layerand the bend elastic constant Kof at least one kind of liquid crystal compounds in the liquid crystal composition constituting the liquid crystal composition layeris 20 pN or more.

Liquid crystal display element

The novel benzamide derivative represented by formula (1) and the novel anilide derivative represented by formula (13) of this invention has differentiation-inducing effect, and are, therefore, useful a therapeutic or improving agent for malignant tumors, autoimmune diseases, dermatologic diseases and parasitism. In particular, they are highly effective as an anticancer drug, specifically to a hematologic malignancy and a solid carcinoma.

A charging member, which is to be provided in contact with an object member and to which a voltage is to be applied to electrostatically charge the object member, has a substrate, and a metal layer and a surface layer of a seamless tube. The charging member may be used with a process cartridge and an electrophotographic apparatus.

Charging member, and process cartridge and electrophotographic apparatus

A contact charging member to be abutted against a charge-receiving member and supplied with a voltage for charging the charge-receiving member is provided. The charging member includes an electroconductive substrate, an elastic layer and a surface layer disposed in lamination. The surface layer comprises crosslinked polymer crosslinked by irradiation with an electron beam. The surface layer may preferably be in the form of a seamless tube formed of the crosslinked polymer. The surface layer crosslinked by electron beam irradiation is less liable to suffer from transfer of a crosslinking agent or a decomposition product thereof to the charge-receiving member. Accordingly, the charging member shows improved durability and stably uniform charging ability suitable for electrophotographic image formation under various environmental conditions.
