Abstract: An external connection terminal connector as a separate part that mounts the igniter is abolished, and the external connection terminal is integrated with the igniter itself. The igniter has the electronic components mounted on an internal wiring substrate, and the electronic components within the igniter and the external connection terminal are directly connected by wire bonding.

Abstract: A method for introducing hydroxyl groups into vitamin D compound at the 1.alpha.- and/or 25-positions in the presence of a cyclodextrin compound by the use of a reaction mixture containing a microorganism being capable of hydroxylating vitamin D compound or a enzyme produced from the microorganism, is disclosed.

Abstract: A DNA fragment or a restriction enzyme-digested DNA fragment, the DNA fragment containing a gene, acyA, encoding a 3-acylation enzyme for macrolide antibiotics, characterized by being derived from a strain belonging to the genus Streptomyces, having a size of about 1.8 kb or about 3.2 kb, and having a DNA base sequence shown in a restriction enzyme map shown in FIG. 1(A) or FIG. 1(B), respectively, in the attached drawing. 3-Acylated macrolide antibiotics can be produced advantageously using macrolide antibiotics-producing bacteria transformed with vector plasmids having inserted therein the DNA fragment.

Abstract: A DNA fragment containing acyB gene coding for an enzyme capable of acylating the 4"-position of a macrolide antibiotic, said DNA fragment being derived from a microorganism of the genus Streptomyces, having a size of about 3.1 kb and being characterized by the restriction endonuclease map shown in FIG. 1 , and a DNA restriction fragment resulting from digestion with a restriction endonuclease; a recombinant DNA plasmid containing this DNA fragment; a microorganism transformed with this recombinant plasmid; and a process for producing a 4"-acylated macrolide antibiotic by using the transformant.

Abstract: This invention provides a blood typing training kit comprising a red blood cell model and an antiserum model with no use of human blood in experiments for blood agglutination and in learning of blood typing, the red blood cell model being an easily available granule which can be suspended in water such as agarose bead, Sepharose, cellulose, Sephadex, cellulofine, alginate, tamarind polysaccharide, gelatin, xanthan gum, etc. or the saccharide- or protein-bound form thereof and the antiserum model being lectin, boric acid-containing liquid or immunoglobulin G.

Abstract: A floppy disk drive in which a frame, disposed in opposition to a base to define a path for a magnetic medium therebetween, is formed of a plate material which is suitably bent so as to facilitate mounting of a clamp and a clamp arm thereon while maintaining its function to guide a magnetic medium.

Abstract: A group of novel depsipeptide antibiotics, neoviridogriseins I, II and III are produced by fermentation of Streptomyces sp. P8648 (FERM-P 3562; ATCC 31289). The antibiotics are highly active against Gram-positive bacteria and mycoplasmas.
