Abstract: A housing includes a first wall and a second wall. The first wall and the second wall face each other in a first direction. A printed circuit board is accommodated in the housing with one surface of a substrate facing the first wall. The housing has a through hole. The through hole extends from an outer surface through an inner surface of the housing. The through hole is open in the inner surface of the housing along a second direction. The second direction is orthogonal to the first direction.

Abstract: The blinking device includes multiple power terminals, multiple load terminals, multiple contact switches, a control circuit, and multiple mounting substrates, and a case in a box shape for accommodating these therein. The multiple contact switches are individually associated with multiple power supply paths individually connected to multiple pairs each defined as a pair of one power terminal of the multiple power terminals and one load terminal of the multiple load terminals. At least one power supply path of the multiple power supply paths is formed on at least one of a front face, where at least one contact switch is mounted, and a rear face, where no contact switch is mounted, of each of the multiple mounting substrates. The case is configured to accommodate the multiple mounting substrates so that the multiple mounting substrates are stacked in a thickness direction.

Abstract: A terminal cover is capable of improving the workability. The terminal device includes a first cover portion to be positioned above the first screw terminals, wherein the first cover portion including the first operation openings which respectively expose screws of the first screw terminals, a second cover portion to be positioned above the second screw terminals, the second cover portion including the second operation openings which respectively expose screws of the second screw terminals. And the terminal device further includes a connecting portion connecting the first cover portion with the second cover portion and including wire insertion holes through which electric wires connected to the first screw terminals respectively pass and wire insertion paths which communicate with the wire insertion holes and through which the electric wires respectively pass, each insertion path being provided on an upper surface of the second cover portion between two adjacent second operation openings.

Abstract: A promoter of a glyceraldehyde-3-phosphate dehydrogenase gene of Acremonium chrysogenum and a transformant which is obtained by using the expression plasmid containing the promoter and is capable of producing a cephalosporin are disclosed.

Abstract: A novel urease having an optimal pH for activity in the acidic region is produced by a microorganism belonging to the genus Lactobacillus or Streptococcus. The urease is superior to the conventional urease in pH stability, temperature stability and alcohol stability.

Abstract: Ethyl carbamate in an alcoholic liquor is decomposed by contacting the alcoholic liquor with a culture broth or processed matter thereof obtained from a microorganism which belongs to the genus Gluconobacter, Flavobacterium, Arthrobacter, Achromobacter, Alcaligenes, Pseudomonas, Klebsiella, Rhodotorula, Rhodosporidium, Trichosporon or Candida, and is capable of decomposing ethyl carbamate. The alcoholic liquor is improved in quality, and has a low ethyl carbamate content.

Abstract: Alcoholic liquors containing carbamide are treated with the urease which has the optimal pH for the activity in an acid region, especially in the region of pH2 to 5. By such treatment, the carbamide can be completely decomposed and removed from the alcoholic liquors in a much smaller amount of urease and in a short time as compared with a conventional treatment according to a urease having the optimal pH in the neutral to alkaline region. This method is more advantageous from the viewpoint of practical use and the quality of the thus obtained alcoholic liquors are superior to that obtained by the conventional treatment.

Abstract: A method of producing guanosine using an adenine-requiring microorganism, in which method the amount of the adenine-containing material to be added to the initial medium is restricted to not more than 50% of the required amount and, after the adenine-containing material added to the initial medium has been consumed almost completely, the remainder of the required amount is added intermittently or continuously.

Abstract: In a fermentation procedure for the production of nucleosides i.e. inosine and/or guanosine using an adenine-requiring microorganism, the fermentation is carried out by allowing a source of adenine to be present in the medium in an excess amount over the amount of adenine that would be conductive to a maximum yield of inosine and/or guanosine in aerobic culture using ordinary air, and cultivating the microorganism while an oxygen-rich gas is bubbled into the medium. Thus, inosine and/or guanosine are accumulated in high yield in the fermentation broth.

Abstract: A method of producing inosine and/or guanosine comprising cultivating a microorganism in a medium containing a carbohydrate, in which method a carbohydrate is added either continuously or intermittently to the medium when and in the state that the concentration of the carbohydrate in the medium is less than about 1 percent so that the carbohydrate concentration of the medium is maintained below about 1 percent.

Abstract: A novel antibiotic P-2563 is produced by cultivating a microorganism of the genus Pseudomonas.The antibiotic is useful as a drug for the treatment of pustule, and also useful as a disinfectant.
