摘要:
A recombinant .beta.-amylase which is superior to the original recombinant .beta.-amylase in thermostability has been obtained by a site-directed mutagenesis with the recombinant .beta.-amylase gene coding 531 amino acid residues. Substitutions were MET.sub.181 of said enzyme with Leu, Ser.sub.291 with Ala, Ile.sub.293 with Val, Ser.sub.346 with Pro, Ser.sub.347 with Pro, Gln.sub.348, with Asp and Ala.sub.372 with Ser.

摘要:
A seal member is attached to a cover which occludes a gear case as a housing unit. The seal member is formed of elastomer and integrally formed with: a plate-shaped portion formed into a disc shape which covers the inner surface of the cover; an inner seal portion which is positioned on the inner peripheral edge of a through-hole, and comes into sliding contact with the outer peripheral surface of an output member; an outer seal portion which is positioned on the periphery of the cover, and comes into contact with the opening end of the housing unit; and anchor portions which latch onto the front surface of the cover via mounting holes provided to the cover. The boundary between the seal member and the cover extends only to the outside of the gear case, and does not extend to the inside of the gear case.

摘要:
An isolated and purified nucleic acid comprising a gene specifically expressed in hop lupulin glands. Hops are dioecious, and only female plants bear cones, the lupulin glands of which contain secondary metabolic products which provide bitterness and flavor to beer. These secondary metabolic products contain some pharmacologically effective compounds. In order to breed a more useful cultivar of hops by manipulating the constituent of such useful secondary metabolic products relying on genetic engineering techniques, this invention provides an isolated and purified nucleic acid comprising a gene specifically expressed in hop lupulin glands. By using this nucleic acid, it is possible to develop a novel method for breeding hops with transformation techniques and molecular selection techniques. Furthermore, the present invention also provides a nucleic acid comprising the regulatory region for specifically expressing genes in lupulin glands. This nucleic acid can be used also for hop breeding.
摘要:
A conductive pattern of a first layer isolated by an isolation trench is formed on a conductive foil, and a plurality of layers of the conductive patterns are formed thereon to create a multilayered wiring structure, and furthermore, a circuit element is mounted and molded with an insulating resin and the back surface of the conductive foil is etched. It is possible to implement a method of manufacturing a circuit device which provides very power saving and is suitable for mass production, then the circuit device having conductive patterns of a multilayered structure are provided.
摘要:
After conductive patterns are formed on the conductive foil every block by employing isolation trenches, conductive plating layers are arranged selectively on the conductive patterns. Therefore, it is possible to accomplish the circuit device manufacturing method by which the die bonding of the circuit elements can be applied stably and the wire bonding can also be applied stably and which can fit to the mass-production while saving the resource.
