    摘要: Fumaric acid is produced by reacting a culture of a microorganism which produces maleate isomerase that exhibits a maximum activity at not less than 50.degree. C. or a treated product thereof with maleic acid in an aqueous solution, and isomerizing maleic acid to produce fumaric acid. L-aspartic acid is produced by reacting both of a culture of a microorganism which produces maleate isomerase or a treated product thereof and a culture of a microorganism which produces aspartase or a treated product thereof with maleic acid and ammonia in an aqueous solution, producing L-aspartic acid from maleic acid and ammonia by enzyme reactions, and recovering L-aspartic acid from the reaction mixture.

    摘要: An osteotomy assistance kit includes a bone treatment assistance device and an attaching position confirmation device. The attaching position confirmation device includes a feature point indication rod to be applied via a tip portion to a feature point of the bone, a rod support unit that removably supports the feature point indication rod such that the tip portion is indicating the feature point of the bone, and a second support member that movably supports the rod support unit and indicates one of scales on the rod support unit. The bone treatment assistance device includes cutting slits, and first guide holes that guides first rods set to a predetermined positional relation. The second support member of the attaching position confirmation device is attached to the protrusion of the bone treatment assistance device.

    摘要: In order to melt snow and prevent freezing without consuming energy wastefully and to monitor a road surface state remotely, a road surface sensor includes: a rotating stand provided so as to be reciprocatingly rotatable upward on the road surface; a snow-melting/freezing heat quantity measurement dummy road surface having an electric heater buried therein and to use as a reference road surface for heat quantity measurement to derive a melting heat quantity for snow falling on the surface and a heat quantity required for freezing prevention; a reference light irradiating/reflected light receiving device that is attached so as to be rotatable with the rotating stand; a space reflected light receiving device; a non-contact road temperature measuring device; a non-contact snow cover depth measuring device; a road surface image pickup device; and a moisture sensor. The reference light irradiating/reflected light receiving device includes a reference light irradiating device for irradiating reference light and a reflected light receiving device for receiving reflected light of the reference light from the road surface, and the reflected light receiving device separates and receives only reflected light of the reference light out of the reflected light from the road surface.
