Disclosed is a polymerizable liquid crystal compound having at least one polymerizable reactive group and showing nematic liquid crystal properties, having a &Dgr;n/n value of 0.14 or more wherein n is average refractive index and &Dgr;n is extraordinary light refractive index (ne) minus ordinary light refractive index (no), and being aligned by application onto an alignment film.
摘要:
The present invention provides an activator in arylamination using a palladium compound as a catalyst, which is superior to conventional phosphines in stability and performance. With the phosphine sulfide as an activator, an arylamination reaction achieves improved selectivity to produce a desired aromatic amine in an obviously increased yield as compared with a reaction using the corresponding phosphine compound. Moreover, the phosphine sulfide of the invention is impervious to oxidation and exists stably in air and therefore sufficiently withstands use on an industrial scale.

A mounting structure including: an outer housing having a first locking portion; a ceiling including a lamp opening portion in a central portion thereof; an inner housing including: a first locking facing portion which is locked in the first locking portion of the outer housing; and a second locking portion on and directly attached to the inner housing; and a reinforcement having a second locking facing portion which is locked on the second locking portion of the inner housing. The ceiling is fixed between the outer housing and the inner housing by locking the first locking facing portion of the inner housing in the first locking portion of the outer housing via the lamp opening portion in the ceiling. A bracket portion shaped so as to follow a shape of an upper side of the ceiling is provided along an outer circumference of the inner housing.
摘要:
A disposable lancing device including: a housing; a spring member; a lancet having a skin puncture needle, the spring member and the lancet being housed within the housing such that a needle tip of the skin puncture needle is adapted to be projected out from the housing under urging of the lancet by the spring member to perform skin puncture procedure; and a protective cap having a needle passage hole and covering the needle tip of the skin puncture needle, the protective cap being adapted to separate from the skin puncture needle and rotate so that the needle passage hole of the protective cap is positioned on a path of projection of the skin puncture needle, and the skin puncture procedure is performed with the protective cap supported on the housing.
摘要:

A method for producing a chemical compound, comprising contacting a substrate with a molecular oxygen in the presence of the above-mentioned oxidation catalyst.
摘要:
A method of coloring a surface of a zirconium-based metallic glass component that includes the step of imparting interference colors by carrying out an anodizing process using an alkaline solution to form a film having a thickness of 300 nm or less on the surface of the zirconium-based metallic glass component.
摘要:
A supported composite particle material comprises: a composite particle formed of an oxidized nickel and X (wherein X represents at least one of elements selected from the group consisting of nickel, palladium, platinum, ruthenium, gold, silver and copper); and a support on which the composite particle is supported, the supported composite particle material having a supported layer in which the composite particle is localized.
摘要:
Provided is a safety needle assembly for protecting a needle point, a safety type needle assembly having a curved portion, to which an erroneous piercing preventing mechanism is added, or a safety type Hoover needle assembly thereby to prevent the piercing accident. The safety needle assembly comprises a needle having a point at its leading end, a hub for holding the root end portion of the needle, and a leading end protecting portion. The safety needle assembly is characterized by further comprising a restricting portion for restricting the distance between the needle and the hub, in that the leading end protecting portion includes a mechanism for warping the needle point, when the leading end protecting portion moves the leading end of the needle to a projecting position, thereby to accommodate the needle point in the inner side of the leading end protecting portion, so that the leading end of the needle is protected.

A catalog of images whose lightness has been changed in accordance with human vision is generated. For this purpose, a first image having reference shadow lightness, a second image having reference highlight lightness, a third image having desired lightness, a fourth image having lightness that is visually perceived to evenly divide the lightness between the first image and the third image, and a fifth image having lightness that is visually perceived to evenly divide the lightness between the third image and the second image are generated. The first to fifth images are included in a catalog image.
