摘要:
According to the present invention, the E. coli mutant strain having chromosomal DNA that is at least 470 kbp shorter than that of a wild-type E. coli strain exhibits such a property that the number of the cells after a certain period of culture is greater than a wild-type strain. Thus, by culturing the mutant strain in a medium so as to generate and accumulate a useful substance in the culture, a useful substance such as proteins, peptides, amino acids, nucleic acids, vitamins, saccharides, organic acids, and lipids can be efficiently produced.

The present invention is directed to a process for producing trans-4-hydroxy-L-proline, which is useful as a raw material for medicines or as an additive to foods. In the process, L-proline is converted into trans-4-hydroxy-L-proline in the presence of an enzyme source which is derived from a microorganism belonging to the genus Dactylosporangium, Amycolatopsis or Streptomyces and which catalyzes the hydroxylation of L-proline into trans-4-hydroxy-L-proline, a divalent iron ion and 2-ketoglutaric acid, in an aqueous medium, and the produced trans-4-hydroxy-L-proline is collected from the aqueous medium. In addition, the present invention is directed to a process for producing trans-4-hydroxy-L-proline, wherein the L-proline biosynthesis activity of the host cell of the transformant is reinforced.

摘要:
In an inertia-press-fit method in which a kinetic energy is applied to at least one of two members in a direction which causes the two members to approach each other, and the two members are press-fitted with each other, an end surface 80 of the first member 10 and a bottom surface 82 of the second member 12 are caused, for stabilizing a relative position of the two members at a time when the press-fitting ends, to butt each other to define the relative position of the two members 10, 12 at the time when the press-fitting ends and, immediately after the butting, at least one of the two members 10, 12 is caused to plastically deform and thereby absorb a remaining kinetic energy of the one of the two members. Thus, the relative position of the two members 10, 12 when the press-fitting ends is stabilized. In the case where respective plastic-deformation capabilities of the two members 10, 12 are great, a maximal value occurs to a graph whose axis of abscissa represents kinetic energy and whose axis of ordinate represents amount of deviation of relative position of the two members. If the respective plastic-deformation capabilities of the two members 10, 12 are so chosen as to decrease the maximal value, then the amount of deviation of the relative position is decreased even though the accuracy of control of the applied amount of kinetic energy may be low.
摘要:
A method of continuously casting molten metal has the step of feeding molten metal into a mold to produce a casting continuously while generating an electromagnetic field in the mold by applying a high frequency to the mold. The application of the high frequency is controlled in such a manner that a magnitude of an electromagnetic field which is applied to a solidification shell forming start location of the mold becomes equal to or greater than a minimum required flux density to be applied to the mold. The minimum required flux density is determined according to the following equation: B min = 1130 × t n - 5 f × ( t n - 0.05 ) where t n = cos - 1 ( v / 2 π × f m × a ) / ( π × f m ) Bmin: minimum required flux density (gauss) tn: negative time strip (second) f: frequency in electromagnetic field (kHz) v: casting velocity (m/sec) fm: number of oscillation or frequency of mold (Hz) a: one-way stroke of mold (m).
摘要:
A data transfer method transfers data to an information-side driver for driving a display apparatus. Wherein, driver circuits each comprise chip address/video data discrimination circuit and a unit driver are mounted around the display apparatus. A unique chip address is set for each of the unit drivers by a hardware pattern. Data exchange with the driver circuits is performed so that chip address information and video data information are time-divisionally transferred to the target unit driver using a chip address/video data common bus line and a chip address/video data discrimination control signal.
