Abstract:
A target to be used in forming a transparent thin oxide film having a high refractive index by direct-current sputtering and a method of forming the film by using the target. Although it has been a practice to form a highly refractive film by direct-current sputtering wherein a metallic target is sputtered in an oxygenic atmosphere, this method is problematic owing to the extremely low speed of film formation. An alternative method therefor comprises using oxide ceramics as the target, but this method is also problematic in that the ceramics are nonconductive and hence direct-current sputtering is difficult. The invention method enables a highly refractive film to be produced rapidly by direct-current sputtering by using a target mainly comprising a metal oxide, MOx, wherein oxygen is contained in a stoichiometrically insufficient quantity and M represents at least one metal selected among Ti, Nb, Ta, Mo, W, Zr and Hf.

Abstract:
An expression vector capable of expressing in a fission yeast Schizosaccharomyces pombe; a multicloning vector for constructing the expression vector; a method of constructing the expression vector; a transformant holding the expression vector; and a process for producing a foreign protein by using the transformant. The multicloning vector has a sequence of -ACATGT- starting with the 5' side at the tip of the multicloning site as the restriction enzyme recognition site for introducing a structural gene of a foreign protein. An expression vector is constructed by introducing a structural gene of a foreign protein by using the above recognition site in such a manner that the tip of the structural gene will have a sequence of -ACATGN- (N being an arbitrary base) starting with the 5' side and that the ATG region of the sequence will function as a translation initiation site of the structural gene. Since it is possible to use an arbitrary base as the N in the sequence of ATGN of the expression vector, it becomes possible to introduce a structural gene of any foreign protein and to express the structural gene to a high level.

A method of treating an outdoor article which comprises forming athin coating on the surface of a hydrophobic synthetic resin coating of an outdoor article by treating the surface with a surface treatment comprising 0.01 - 100 parts by weight of a silane compound (A) having a silanol group formed by hydrolyzing a tetraalkoxysilane or oligomer thereof and 100 parts by weight of a medium. It can prevent streaky stain from occurring in the part where raindrops gather and flow , such as the lower part of a window frame of a building.
Abstract:
A process for producing a fluoropolymer containing a fluoroolefin unit as the principal constitutional unit, which comprises employing CF3(CF2)nCH2CH3 or CF3(CF2)nH (wherein n is an integer from 1 to 8) as a polymerization medium and CF2ClCF2CHClF and/or CF3CF2CHCl2 as a chain transfer agent. The process affords a fluoropolymer having favorable resistances to heat, solvents, chemicals, etc., by the use of a polymerization medium which is less apt to cause environmental destruction. The chain transfer agent has good compatibility with the polymerization medium which is less apt to cause environmental destruction and thus can effectively produce a fluoropolymer having favorable resistances to heat, solvents, etc. Moreover, it has high affinities for both the objective polymer and the polymerization medium, and can easily be handled in the post-treatment step such as granulation and drying.
