摘要:
A method for fabricating a sample stage for microspectrometric analysis in which an optical material is used, wherein said method is characterized in that an optical material is immersed in a liquid obtained by dissolving a water-repellent or oil-repellent perfluoroalkyl-polyether-group-containing silane compound in a solvent, the immersed optical material is heated and subsequently washed, and the surface of the optical material is surface-modified to become water- or oil-repellent.

Provided is a device capable of evaluating an atomic emission profile or cathode luminescence at an exceptional depth-direction resolution at the same time as or separately from a surface analysis method using ion sputtering. An ion-beam-induced atomic emission spectrometer wherein a commercial ultra-high vacuum surface analysis apparatus is provided, within a radius of 30 to 50 cm from a sputtering ion or electron beam irradiation position, with an optical system of a light emission detector and a spectrograph for spectroscopy of an atomic emission spectrum or cathode luminescence emitted from a sample.

Disclosed is a carbon fiber made from an acrylic fiber, the carbon crystal of which has a crystal size Lc of 15 to 65 Å as determined by the wide angle X-ray diffractometry. This carbon fiber has regions with a lower crystallinity in the surface layer portion thereof than that of the central portion thereof, and the compressive strength σ cf (GPa) of the single filament thereof determined by the loop method satisfies formula (I): σ cf ≧ 10.78 - 0.1176 x Lc (I). The carbon fiber is produced by ionizing in vacuo an atom or molecule which is solid or gaseous at normal temperature, accelerating the ionized atom or molecule by an electric field, and implanting the accelerated ionized atom or molecule in a bundle of carbon fibers.

摘要:
A process for producing biologically active fused proteins whereby novel biologically active fused proteins usable as a remedy or a diagnostic drug or applicable to gene therapy can be efficiently produced by appropriately selecting the optimum linker polypeptide. This process comprises incubating transformants obtained by the transformation by expression vectors which contain the DNA sequences encoding the amino acid sequences of proteins represented by the following formula: A-X-B wherein A and B represent respectively the subunits of a dimer protein or biologically active proteins and may be the same; and X represents a linker polypeptide.

An electrophoresis fractionator comprises a multiplicity of separate cells (10, 11) provided on respective contact surfaces of two members (1, 2) which are in contact with each other movably relative to each other and move relative to each other to enable alternate switching between a position where the multiplicity of cells (10, 11) are connected to a single electrophoresis passage P together and a position where the multiplicity of cells (10, 11) are separated from one another, and electrodes (14, 15) provided on both respective ends of the electrophoresis passage P which is formed to be single.
