The directional solidification  of lead can be performed by raising electric heater.

Title: Circuit for improving picture quality of sons picture in pip (picture in picture)
Inventor: YO KWON
IPC: H04N5/45
Filed: 1990-03-27
Granted: 1992-11-02
Abstract: The circuit for improving the picture quality of  picture  in picture (PIP) without increasing the capacitance of  memory  sect. comprises:  a  demodulator  (1)  demodulating  the  applied  video signal; an A/ D convertor (2)  converting  the  demodulated  analog signal into the digital  signal  by  sampling  with  the  constant frequency; an input data latch (3) outputting the  digital  signal outputted from the A/D convertor; a memory part  (4)  storing  the data outputted from the latch; a memory controller (5); an  output data latch  (6) outputting  the  data  of  memory  sect.;  a  D/A convertor converting the digital signal outputted from  the  latch (6) into the analog  signal;  a  modulator  outputting  the  video signal from the D/A convertor.

Title: Process for producing cleaning powder detergent
Inventor: CHA SEUNG-HO
IPC: C11D11/02
Filed: 1990-04-03
Granted: 1992-06-15
Abstract: The powdered detergent is prepared  by  (A)  upward  spraying 3-15 wt.%  (with  respect  to  finally  dried  detergent  powder) zeolite- dispersed solution containing 25-45 wt.% solid  part  from the bottom of countercurrent spray dryer so that zeolite  solution is attached to  detergent  powder,  (B)  drying  and  evaporating moisture on outer surfaces of detergent particles, while  downward spraying detergent slurry from the  top  of  countercurrent  spray dryer, and (C) completely drying and evaporating  moisture  inside detergent particles.
