摘要:
The invention relates to a high molecular weight .beta.-1,3-glucan composed of repeated glucopyranose units, each unit being represented by the formula: ##STR1## The .beta.-1,3-glucan exhibits anticarcinogenic activity. A process for producing said glucan is also claimed.
摘要:
The present invention provides a process for preparing a optically active .beta.-(S)-aminoglutaric acid monoalkyl ester of the formula: ##STR1## wherein R is a lower alkyl group having 1 to 4 carbon atoms, which comprises subjecting a .beta.-N-protected aminoglutaric acid dialkyl ester of the formula: ##STR2## wherein each R is as defined above and A is an easily removable protecting group, to an action of an enzyme produced by a microorganism belonging to the genera Flavobacterium, Achromobacter, Xanthomonas, Alcaligenes, Serratia, Gluconobacter, Chromobacterium and Acetobacter, to selectively hydrolyze only one of the two ester groups, and then removing the protecting group.
摘要:
Phenopicolinic acid is produced by culturing a strain of Paecilomyces. The compound, which may be alternatively named as 5-(4-hydroxybenzyl)-2-pyridinecarboxylic acid, is a hypotensive agent.
摘要:
Apparatus for exposing an image of a desired pattern, such as a lead frame pattern for producing lead frames of IC devices, with a predetermined pitch on a photosensitive beltlike material consisting of a film carrier and a photoresist-coated metallic foil laminated on the carrier.Apparatus typically comprises a first means for positively supporting and accurately positioning the beltlike material at an exposing position, a second means for intermittently conveying the material and a third means for photoelectrically detecting the amount of the movement of the beltlike material to control the first and the second means.
摘要:
There is disclosed a new antibiotic called calvatic acid having the structure p-carboxyphenyl-azoxycarbonitrile and processes for its production by fermentation and processes for its recovery and purification. This substance is effective in inhibiting the growth of Gram-positive bacteria and carcinoma.

摘要:
According to one embodiment, a recording/reproduction apparatus includes a power source controller. The power source controller includes a determination unit, a stand-by mode execution unit, and a pause mode execution unit. The determination unit determines whether or not an event associated with at least one of recording and reproduction of the information signal occurs at start-up time. The stand-by mode execution unit executes a stand-by mode in which the power level of each of the encoder, the decoder, the recording medium, and the plurality of signal processors is controlled to be lower than a predetermined level. The pause mode execution unit executes a pause mode in which the power to each of the encoder, the decoder, the recording medium, and the plurality of signal processors is turned off, and the power level of the process controller is controlled to be lower than the predetermined level.
