A magnesium base alloy pipe having high strength and toughness is provided along with a method of manufacturing such pipes. A magnesium base alloy pipe, wherein the pipe is produced by drawing a pipe blank of a magnesium base alloy comprising containing either of the following ingredients (1) or (2): (1) about 0.1-12.0 mass % of Al; or (2) about 1.0-10.0 mass % of Zn and about 0.1-2.0 mass % of Zr. The novel alloy pipe is manufactured by a method comprising steps of providing the above-described pipe blank, pointing the pipe blank, and drawing the pointed pipe blank. The drawing step is executed at a drawing temperature above approx. 50° C.

A method for producing D-lactic acid in high yield, and to provide a method for producing D-lactic acid with high selectivity, in which optical purity is high and a by-product organic acid is small. In one aspect, a microorganism, wherein activity of pyruvate formate-lyase (pfl) is inactivated or decreased, and further activity of Escherichia coli-derived NADH-dependent D-lactate dehydrogenase (ldhA) is enhanced, is cultured to efficiently produce D-lactic acid. With regard to a method for enhancing ldhA activity, by linking, on a genome, a gene encoding ldhA with a promoter of a gene which controls expression of a protein involved in a glycolytic pathway, a nucleic acid biosynthesis pathway or an amino acid biosynthesis pathway, suitable results are obtained compared to the method for enhancing expression of the gene using an expression vector. A microorganism in which a dld gene is substantially inactivated or decreased is cultured to produce high quality D-lactic acid with reduced concentration of pyruvic acid.

There are provided a bracket 3 that has a frame section 11 integrally formed by a transparent material, an apparatus mounting section 12 disposed in an inner peripheral edge of the frame section, and parts fixing sections 13, 13, . . . disposed on the outside of the frame section; a front panel 2 that is formed by a transparent material and disposed on the front surface side of the bracket; an apparatus body section 4 that has a screen surface 4a and is mounted at the apparatus mounting section of the bracket; holding members 31, 31 that hold the front panel and the bracket in the state that they are connected together at the front and rear; and functional sections that are fixed to the parts fixing sections of the bracket so as to be disposed on the outside of the front panel, and that sends and receives electric signals to exhibit a predetermined function. Signal paths 35, 35 to perform sending and receiving of electric signals between the apparatus body section and the functional sections are formed in the inside of the bracket or in a boundary portion between the front panel and the bracket. This enables sending and receiving of electric signals between the apparatus body section and the functional sections that send and receive electric signals to exhibit a predetermined function, while maintaining good design quality.

A photosensitive layer contains an electron-transfer agent that makes use of a compound represented by the following general formula (1): wherein R1 through R4 are each independently selected from the group consisting of hydrogen, cyano, nitro, halogen, hydroxyl, alkyl, aryl, heterocyclic ring, ester, alkoxy, aralkyl, allyl, amide, amino, acyl, alkenyl, alkynyl, carboxyl, carbonyl, and carboxylic acid; X is selected from the group consisting of oxygen, sulfur, and ═C(CN)2; and W is a 4- to 8-membered ring.
摘要:
A stand on which a flat panel display main body is placed has low-pitched sound speakers built therein and a speaker of the flat panel display main body and the low-pitched sound speakers of the stand are combined together to construct a powerful sound system with large sound volume. The low-pitched sound speakers are located at the back side of the flat panel display main body when the flat panel display main body is placed on the stand. In a flat panel display apparatus composed of the flat panel display main body having the speaker built therein and the stand supporting this flat panel display main body thereon, it is possible to easily realize a powerful sound system using the low-pitched sound speakers (woofers) without requiring any extra space.
摘要:
A semiconductor substrate is of first-conductivity-type and has a principal surface. A first semiconductor region and a second semiconductor region are of second-conductivity-type and formed apart from each other in the principal surface of the semiconductor substrate. A third semiconductor region is of second-conductivity-type and formed on the first semiconductor region. The third semiconductor region has an impurity concentration higher than that of the first semiconductor region. A fourth semiconductor region is of first-conductivity-type and formed on the third semiconductor region. A first main electrode is formed on the fourth semiconductor region. A second main electrode is formed on the second semiconductor region. A gate electrode is formed, at least on the first semiconductor region and on the principal surface of the semiconductor substrate between the fourth semiconductor region and the second semiconductor region, with a gate insulating film therebetween.
