摘要:
A planetary gear mechanism includes a planetary carrier and pinions rotatably carried on the planetary carrier through pinion shafts. An annular lubricating oil supply member is mounted on a ring gear supporting member which supports a ring gear on its outer periphery and which is rotatable. The lubricating oil supply member has a plurality of fins formed radially thereon. The lubricating oil received within the lubricating oil supply member while submerged in the lubricating oil is scattered by a centrifugal force and supplied to oil reservoirs defined in the adjacent side of the planetary carrier and then from the oil reservoirs via oil passages in the pinion shafts to the needle bearing which supports the pinions. With the above construction, it is possible to effectively supply the lubricating oil to the pinion shafts of the planetary gear mechanism when the planetary is in a fixed position.

Disclosed is a novel antibiotic SF-2107 series substance consisting essentially of Substance SF-2107 A-1, Substance SF-2107 B and/or Substance SF-2107 C, each having the phisico-chemical properties as described in the specification, which substance exhibits an antibacterial activity against both gram-positive and gram-negative bacteria and is useful for pharmaceuticals, bactericides, disinfectants, etc. Also disclosed is a process for preparing the substance.
摘要:
Antibiotics, designated as SF-2080A substance and SF-2080B substance, are described, and are obtained by cultivating an SF-2080 substance-producing strain belonging to the genus Streptomyces, for example, Streptomyces sp. SF-2080 (FERM-P No. 5072, ATCC No. 31673), in a nutrient medium, and recovering the desired substance from the culture.
摘要:
An antibiotic SF-1942 substance produced by cultivating an SF-1942 substance producing strain of the genus Streptomyces in a nutrient medium under aerobic conditions to produce and accumulate the SF-1942 substance in the nutrient medium and isolating the SF-1942 substance from the fermentation broth followed by purification and a process for the production of the antibiotic SF-1942 substance. The SF-1942 substance is effective as an antimicrobial agent and an antitumor agent against Sarcoma 180 tumor cells in mice.

New antibiotics SF-1130-x.sub.1 substance and SF-1130-x.sub.2 substance are produced by cultivating a microorganism Streptomyces myxogenes SF-1130 now deposited under FERM-P. 676 and ATCC. 31305 in a liquid culture medium under aerobic conditions, and these antibiotics may be isolated from the fermentation broth and are useful as an activator for enhancing the host defense system in living animals. The activity of these antibiotics may be improved when used in combination with one or more of maltose, maltotriose, maltotetraose, maltopentaose, maltohexaose and maltoheptaose.
摘要:
A new antibiotic designated as SF-1623 substance exhibiting a useful antibacterial activity against gram-negative bacteria is now produced by cultivating a new strain ATCC 21999 of the known species Streptomyces chartreusis. The SF-1623 substance in the form of its an alkali metal salt may be recovered from the culture when the cultivation is effected under aerobic conditions in the presence of an alkali metal thiosulfate.
摘要:
This invention relates to a process for preparing a cephamycin type antibiotic substance which comprises cultivating a microorganism belonging to the genus Streptomyces under aerobic conditions and a primary object of this invention is to provide a process for preparing the said product on a simple and industrial scale.
摘要:
An antibiotic SF-2103A substance or a salt thereof, and a process for the production thereof are described, and the process comprises cultivating an antibiotic SF-2103A substance-producing strain in a nutrient medium and recovering the desired substance from the culture broth.
摘要:
New antibiotic, SF-2052 substance is produced by cultivating a microorganism, Dactylosporangium matsuzakiense SF-2052 now deposited under FERM-P 4670 or ATCC No. 31570 in a liquid culture medium under aerobic conditions, and this antibiotic may be isolated from the culture broth by conventional method and is useful as antibacterial agent.
