Title: Decoding apparatus
Inventor: GONDO DEZUZIRO
IPC: H04N19/00
Filed: 1989-02-03
Granted: 1997-05-07
Abstract: A decoding apparatus decodes data, such as a digital video signal or the like transmitted from a coding (transmission) apparatus for coding an original datum with a less number of bits than that of the original datum. Adjacent sample data of a sample datum to be decoded are separated from the transmitted data. These data are compared with the sample datum to be decoded and the correcting datum is generated based on the compared output. The original datum is recovered from the sample datum to be decoded and the correcting datum, thereby the quantizing error or distortion can be reduced without increasing the encoding data amount.

Abstract: The self-aligned storage node trench capacitor cell  is  mfd. by (a) forming a well on the substrate and forming a  deep  trench field oxide film by the masking, oxygen-ion  implanting  and  heat cycle process, (b) forming a gate oxide film, a  gate  polysilicon and a HTO for a cap gate, patterning it, and  then  implanting  Nion, (c) forming a side wall, and then forming a  trench  using  a photoresist, (d) lifting off the photoresist, and then  implanting N+ ion to form a lifhtly doped  drain  (LDD)  structure,  and  (e) forming a high dielectric material and a  polysilicon  for  a  top electrode, and then patterning it. The capacitor  cell  is  useful for a high grade device.

Abstract: 100 wt.pts. of polyarylene sulfide resin; 0.5-20 wt.pts. of high density polyethylene having 0.941-0.965 density; and 25-150 wt.pts. of fiber form filler selected from glass fiber, carbon fiber, silica fiber, titanic acid kalium fiber, titanium fiber, aramide fiber or asbestos fiber. The polyarylene sulfide resin has 10-20,000 poise of melting viscosity at 300 deg.C and 1200/sec shear rate. The obtd. resin compsn. has good appearance and formability for molding.
