Inventor: KAGEYAMA SADAO
IPC: C12P41/00
Filed: 1987-01-12
Abstract: PURPOSE:To easily obtain D-lactic acid having high optical purify, by culturing a microbial strain assimilating L-lactic acid in a medium containing racemic lactic acid or a mixture of the recemic compound and an optically active lactic acid or by contacting the racemic lactic acid, etc., with cultured microorganism. CONSTITUTION:A culture medium is prepared by using racemic lactic acid or a mixture of racemic lactic acid and an optically active lactic acid as a carbon source and compounding the source with a nitrogen source such as urea, inorganic salt such as MgSO4 and, if necessary, a proliferation promoting factor such as yeast extract. The obtained medium is inoculated with a microbial strain (e.g. Bacillus subtilis IFO 3134) belonging to Bacillus genus and having an assimilation rate of L-lactic acid high than that of D-lactic acid. The strain is cultured in the medium at 3-10pH and 20-60 deg.C for several hours several days under supply of air. The microbial cells are separated and removed from the cultured product and the supernatant liquid is concentrated and refined by ion exchange treatment, solvent extraction, etc., to obtain the objective D-lactic acid.

Abstract: PURPOSE: To provide the subject device to be provided at the entrance of a clean room, wherein the floor of the main structure of an air shower chamber is rotated to compensate the dead angle of the injection angle of a high-speed air injection nozzle, whereby removal of dust and miscellaneous bacteria can be carried out, effectively.  
     CONSTITUTION: When an operator wearing a dust-free clothing enters the main structure 1 of an air shower chamber to operate a blast unit 5 and a rotating unit 11, purified germ-free air is injected through respective high-speed injection nozzles 3 -1 , 3 -2  and the like. Simultaneously, since the floor 1a rotates slowly, injected germ-free high-speed air reaches uniformly the dust-free clothing of the operator. By these operations it is possible to wash off smoothly and effectively dusts and miscellaneous bacteria in the main structure 1 of the air shower chamber.

Filed: 1988-01-12
Abstract: PURPOSE:To shorten the detecting/catching time of a mobile object by increasing continuously the aperture of a light beam until the mobile object is caught to stop the increase of the caliber when the mobile object is caught, reducing successively the beam aperture while catching the mobile object to stop the reduction said beam aperture at a prescribed aperture of the tracking light beam and to finish the catching action of the mobile object, and starting a tracking action of the mobile object. CONSTITUTION:The aperture of a light beam LB produced by a light beam generator 110 is increased by a variable condenser lens 120 and scanned into a space in the form of a luminous flux beam LBe. Then the beam LBe is recurred as a feedback beam RB which is incident on a recursive reflector 200 of a mobile object and photodetected. Based on this photodetecting signal, the aperture of the lens 120 is controlled. Then the increase is stopped for the aperture of the beam LBe and this aperture is reduced. The reduction of the aperture of the beam LBe is stopped at a prescribed aperture of a prescribed tracking light beam while catching the reflector 200. The the light beam of a reduced aperture is made incident on the reflector 200 and a scanning mechanism 130 is controlled so that the photodetecting output of the recurring beam RB has no change vertically and horizontally for tracking of the reflector 200. Thus the detecting/catching time of the mobile object can be shortened.
