    摘要: A biological process for producing steroids hydroxylated at the 25-position thereof comprises adding steroids (excluding cholesterol) to the cells or culture liquid of a microorganism of the genus Amycolata or Sphingomonas capable of hydroxylating the steroids at the 25-position thereof to convert a hydrogen atom bonded to a carbon atom at the 25-position of each steroid into hydroxyl group. By this process, steroids(other than cholesterol) can be biologically hydroxylated at the 25-position by using microorganisms other than those of the genus Streptomyces.

    摘要: An element for detecting internal faults in an insulating gas charged electrical apparatus comprises a substrate disposed in the electrical apparatus charged with an insulating gas, a pair of electrodes disposed on the substrate, and a thin metal film covering the pair of electrodes and the exposed surface of the substrate. This film is capable of producing fluorides with low conductivity upon reacting with a decomposed gas produced by internal faults of the electrical apparatus. Since the thin metal film exhibits high response characteristics readily in reaction with even a trace amount of a decomposed gas, it is possible to promptly detect faults occurring in the electrical apparatus, such as a partial discharge or local heating. In addition, a device for detecting internal faults in an insulating gas charge electrical apparatus using the internal fault detection element utilizes an optical signal for transmitting signals. Accordingly, the device is free from electromagnetically induced interference and is capable of remote monitoring because of the low level of loss in signal transmission.
