A process for manufacturing an aluminum support for a planographic printing plate material, the process containing the steps of: (a) electrolytically surface-roughening an aluminum plate in an electrolyte solution containing hydrochloric acid as a main component; and (b) anodizing the surface-roughened aluminum plate, wherein the step (a) contains: (i) a first stage which surface-roughens the aluminum plate employing a sine-wave alternating current; and (ii) a second stage which surface-roughens the aluminum plate employing a controlled sine-wave alternating current using a thyristor so that a current flow starts at a phase angle of 60 to 120 degree of an alternating current cycle.

L-cysteine is produced by culturing a coryneform bacterium in which intracellular serine acetyltransferase activity is increased by transformation with a gene coding for serine acetyltransferase, such modification of an expression control sequence of a gene coding for serine acetyltransferase that expression of the gene in a cell should be enhanced and for forth, preferably in which L-cysteine decomposition system is further suppressed, in a medium to produce and accumulate L-cysteine in culture and collecting the L-cysteine from the culture.

L-Cysteine is produced by culturing a bacterium belonging to the genus Escherichia having an L-cysteine producing ability and modified so that cystathionine-β-lyase activity or cystathionine-β-lyase activity and tryptophanase activity should be reduced or eliminated in a medium to produce and accumulate L-cysteine in the medium and collecting the L-cysteine from the medium.

A four-wheel drive vehicle includes a coupling, which varies the distribution ratio of torque to the front wheels and the rear wheels. The distribution ratio of torque to the front wheels and the rear wheels is determined by the engaging force of the coupling. An ECU sets first to third determination threshold values for the opening degree of a throttle valve of an engine in accordance with the detected vehicle speed. The ECU determines whether the vehicle is in a steady driving state by comparing the detected throttle opening degree with the set first to third determination threshold values and controls the engaging force of the coupling in accordance with the determination result. Thus, the steady driving state of the vehicle is correctly determined.

An apparatus for measuring the dynamic characteristics of the vehicle wheel alignment in non-contact fashion with high accuracy is disclosed. A laser light source (4) emits a laser beam of a predetermined geometric pattern toward the wheel side surface. A laser beam control device (6) controls the width of the laser beam in such a manner as to be radiated only in a predetermined range of the wheel side surface. Two laser light sources (120), (121) emit non-parallel laser beams. A photdetecting device (122) receives the two laser beams and converts them to two corresponding image data. A processing unit calculates the distance between the two images based on the two image data and calculates the wheel alignment based on the same distance.

A method for measuring the viscosity of a green compact sample includes the steps of finding a corrected value V′ of the sample volume of the green compact sample, where the corrected value V′ of the sample volume is a volume occupied by the inorganic powder in the green compact sample; finding a corrected value (dh/dt)′ of the sample deformation rate of the green compact sample, 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 sample; 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.
