摘要:
A polyester film for recording medium, having one major surface thereof provided with a coating layer containing fine particles of 5 to 60 nm diameter and an organic compound, wherein the number of fine surface projections existing on the surface of the coating layer is in the range of 3 million to 100 million/mm2, and the number of surface defects of 120 nm or greater height attributed to foreign matter contained in the film is 30/100 cm2 or less, and wherein the polyester contains a titanium compound substantially not having any particle diameter. Thus, there are provided a magnetic recording tape for digital data recording that can reduce dropouts and excels in durability, and further provided a polyester film that is suitable as a base film thereof.

摘要:
An electrophotographic apparatus includes a plurality of image forming devices, wherein each image forming device includes a developing device having a tip end part and a toner storage part coupled to the tip end part. A thickness of the tip end part is smaller than a thickness of the toner storage part. An exposure device, which is an LED array, is arranged near the tip end part.

摘要:
2-Hydroxymethyl-3,4,5-trihydroxy piperidine, or moranoline, is prepared by culturing a moranoline-producing strain of microorganism of the genus Streptomyces in an appropriate culture medium and thereafter isolating moranoline from the culture medium.
摘要:
2-Hydroxymethyl-3,4,5-trihydroxy-N-alkylpiperidines and their acid addition salts are antihyperglycemic agents. A typical example is 2-hydroxymethyl-3,4,5-trihydroxy-N-methylpiperidine.
