摘要:
L-Cysteine, L-cystine, a derivative or precursor thereof, or a mixture thereof is produced by culturing a bacterium belonging to the family Enterobacteriaceae, which has L-cysteine-producing ability and has been modified so that the activity of a protein encoded by a tolC gene, for example, a protein defined in the following (a) or (b), is increased in a medium, and by collecting L-cysteine, L-cystine, a derivative or precursor thereof, or a mixture thereof from the medium: (a) a protein comprising the amino acid sequence of SEQ ID NO: 2, (b) a protein comprising the amino acid sequence of SEQ ID NO: 2, but wherein one or several amino acid residues are substituted, deleted, inserted or added, increase of which activity in the bacterium improves the ability of the bacterium to produce L-cysteine.

摘要:
An image retrieval assisting apparatus and method for retrieving a desired image program from a number of image programs, such as broadcast contents in a broadcast-contents-recording/reproducing apparatus or a broadcast receiving set. A classification criterion information storage portion stores classification criterion for classifying broadcast contents into a plurality of categories. A program information acquisition portion acquires program information of the broadcast contents. A program information classification portion classifies the program information into the plurality of categories according to the stored classification criterion. An HDD stores the classified program information, and a display displays categories defined by the stored classification criterion horizontally on a monitor screen in a selectable manner and displays only the program information categorized in a selected category vertically on the monitor screen in a selectable manner.

A method for measuring the viscosity of a green compact includes the steps of finding a corrected value V′ of the sample volume of the green compact, where the corrected value V′ of the sample volume is a volume occupied by the inorganic powder in the green compact; finding a corrected value (dh/dt)′ of the sample deformation rate of the green compact, where the corrected value (dh/dt)′ of the sample deformation rate is the difference between the apparent sample deformation rate and the sample deformation rate due to sintering shrinkage; separating a temperature range X in which sintering shrinkage dominates and a temperature range Y in which plastic deformation dominates with respect to the displacement of the green compact; substituting the corrected value V′ of the sample volume for the sample volume V and substituting the corrected value (dh/dt)′ of the sample deformation rate for the sample deformation rate dh/dt in the Gent equation with respect to the temperature range X; and substituting the corrected value V′ of the sample volume for the sample volume V in the Gent equation with respect to the temperature range Y.
