Inventor: WON YONG-MU
IPC: C10L1/10
Filed: 1983-11-23
Granted: 1985-12-30
Abstract: An emulsifier for fuel emulsion is prepared by mixing a nonionic activating agent(I), i.e., etylene oxide compd. having formula C9H19- C6H4-(O-CH2-CH2)3-OH, and an anionic activating agent(II) comprising of a mixture of calcium and magnesium salt of linear chained C10-C12 alkyl benzene sulfonic acid. Weight ratio of calcium salt to magnesium salt is 70 - 90 : 30 - 10. Weight ratio of (I) to (II) is 50 - 75 : 50 - 25. The fuel emulsion is used for combustion to reduce the emission of pollutants, i.e., smoke, SOx, and NOx.

Title: Cultivation with acetate concentration monitoring
Inventor: SIMIJU NORIO
IPC: C12M1/36
Filed: 1988-02-13
Granted: 1990-10-17
Abstract: A method for cultivation of a microorganism or an animal cell or plant cell to produce a metabolite is characterised by monitoring acetate concn. in the culture broth and regulating assimilation of acetate in the culture broth to control the acetate concn. to a set value or less. The acetate concn. may be controlled by regulating assimilation of the acetate through control of a feeding substrate such as a nutrient e.g. casamino acid, an amino acid, glucose or yeast extract. The method is used for e.g. E. coli, yeast, B. subtilis, plant or animal cells, the growth of which is inhibited by acetic acid. The acetate concn. can be reduced to achieve high density cultivation, high cell yield and high prodn. of desired prods.

Title: High speed seek system by using a pilot signal
Inventor: SHIN CHUNG-SUN
IPC: G11B27/10
Filed: 1990-09-08
Granted: 1993-09-22
Abstract: The system comprises a free equalizer (103) synchronized with the signal of the drum head (1);  a  ATP  pilot  signal  detection filter for  detection  of  ATP  signal  from  the  output  of  the equalizer; an edge detection circuit for  edge  detection  of  the output signal; a counter (108) for counting the number of the edge detection circuit output;  a  latch  circuit  part  (109);  a  PWM encoder (110) for modulation of  the  latch  output;  a  low  pass filter (111) for the output of PWM  encoder;  and  a  motor  drive circuit (112) for driving of the drum motor (101).

Title: Method for purification of spiculisporic acid
Inventor: JO KI-HWAN
IPC: C12P17/18
Filed: 1990-09-14
Granted: 1992-09-26
Abstract: A  spiculisporic  acid  is  separated  and   purifyed   from Penicillum  spiculisporium  ATCC  16071  culture  broth   by   (a) concentrating the culture broth, (b) extracting spiculisporic acid by mixing with organic solvent, and (c) filtering the mixed  soln. and removing  organic  solvent  to  obtain  the  precipitate.  The organic solvent is acetone, methanol or ethanol.
