摘要:
A cationic dye-dyeable polyester resin composition comprising a cationic dye-dyeable polyester resin and a melt viscosity depressant.Addition of the melt viscosity depressant to the cationic dye-dyeable polyester resin reduces the melt viscosity of the resin without decreasing the intrinsic viscosity thereby making the resin melt-spinnable. A cationic dye-dyeable polyester fiber with high strength can be obtained from the polyester resin composition.

A new melt viscosity depressant for a polyester resin having a structure of an aromatic carbonyl compound is disclosed.Addition of the melt viscosity depressant to a polyester resin reduces the melt viscosity of the resin remarkably, thereby facilitating mold processing and melt-spinning of the polyester resin composition, from which high strength polyester molding products and polyester fibers can be obtained.
摘要:
A wavelength selection switch that includes an optical component for adjusting an optical path with an image magnification of M that is provided between a second imaging position and a mirror array. Therefore, it is possible to provide a small wavelength selection optical switch with a short optical path length that is capable of reducing the focal length of each of a first lens and a second lens to 1/M while maintaining the structure of the spectral element, the fiber array, and the mirror array according to the related art. Since the optical path length is reduced, it is possible to reduce the number of reflecting mirrors used to convert an optical path and thus reduce the size of a housing. Therefore, it is possible to reduce manufacturing costs.

摘要:
Provided is a rubber composition comprising an inorganic filler, a compound having at least one group A reacting with a rubber and two or more groups B adsorbing on the inorganic filler described above in the same molecule, a compound having the group A reacting with a rubber and an amino group in the same molecule or acrylate or methacrylate having a specific structure and further comprising, if necessary, a silane coupling agent. This makes it possible to provide a rubber composition which is excellent in the dispersibility of an inorganic filler, so that it does not elevate a viscosity of a non-vulcanized rubber and does not damage the processability and which does not bring about roughening on the surface of a rubber and is improved in a storage modulus.
