Title: Production of optically active halogen-substituted alcohol
Inventor: YAMAMOTO HIROAKI
IPC: C12P7/04
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To efficiently synthesize an optically active 4-halo-3-hydroxylactic ester having high optical purity. SOLUTION: Asymmetric reduction of a halogen-substituted ketone such as a 4-haloacetoacetic ester is carried out at a low temperature by utilizing a secondary alcohol dehydrogenase and using an alcohol as a substrate for NADH regeneration to synthesize an optically active halogen-substituted alcohol such as an optically active 4-halo-3-hydroxylactic ester. Toxicity of the halogen- substituted ketone such as the 4-haloacetoacetic acid ester and a halogen- substituted optically active alcohol such as 4-halo-3-hydroxylactic ester to an enzyme is reduced by carrying out the above reaction at a low temperature. Thereby, accumulated concentration of the optically active halogen-substituted alcohol such as the optically active 4-halo-3-hydroxylactic ester can be increased while retaining high stereoselectivity of the secondary alcohol dehydrogenase.

Title: Device for disposing of waste water
Inventor: KAWAMURA HIROSHI
IPC: B01D21/24
Filed: 1978-04-19
Abstract: PURPOSE: To continuously perform the separation and concentration of sludge from waste water through a single apparatus, by providing a sludge conveying concentrator at a sludge pocket of a sludge sedimentation vessel.  
     CONSTITUTION: The sludge is separated from the waste water in the sedimentation vessel 1 and sinks into the sludge pocket 2. The sludge is propelled through a casing 3 by a spiral blade 5. At that time, the grains of the sludge are rearranged so that the solid and liquid of the sludge are separated from each other. After the sludge is transferred into a pipe 6 of smaller inside diameter than the casing 3, the sludge is compressed further in the vertical part of the pipe 6 so that the separation of the solid from liquid of the sludge is accelerated. Because the pipe 6 extends upward above the sedimentation vessel 1, the sludge is removed of water when the sludge is pushed from the upper end of the pipe 6 into a mesh screen 7. Therefore, the sludge can be concentrated without using a separate concentrator.

The signal from the circuit 12 is processed by a subtractor 13, a multiplier 14, and an adder 15, through memory circuits 18-20 for positions, rates of change, and levels. The result is given to the subtractor 7, and only the distance signal which does not include the large error signal is outputted through a comparator 9. Therefore the measuring accuracy can be improved.
