Title: Method for high quality compression of binary text images
Inventor: CHEVION DAN S
IPC: H04N1/411
Filed: 1990-06-15
Granted: 1995-05-30
Abstract: The invention relates to a method for the compression and decompression  of  binary  text  images.   The  method distinguishes between large low-frequency areas and small high-frequency  areas  in  the  original  frame.  For  the low-frequency areas,  a scheme for lossy compression is used,  whereas for the high-frequency areas,  a  scheme permitting   lossless   compression   is   applied.   The compression/ decompression process involves the following five  stages  -  (1)  prefiltering  to  remove  all  black patches (e.g. by removing all black pixels, except where they belong to a large black segment; (2) fast evaluation of  compressibility  by  partitioning  the  images  into mutually  exclusive  segments  and  applying  different compression  modes  to  each  segment;  (3)  connectivity oriented  subsampling  to  reduce  the  resolution  in horizontal  and  vertical  directions  (the  image  is segmented into blocks, and a 1-pixel representation for each block is determined);  (4) lossless compression and decompression where the reduced file is compressed by conventional  techniques;  and  (5)  reconstruction  by sequence reversal (lossless decompression will retrieve the subsampled file,  expansion of the subsampled file through replacement of each pixel by a block having equal value, postfiltering).

Title: Scroll type compressor with improved lubricating arrangement for movable parts thereof
Inventor: FUKANUMA TETSUHIKO
IPC: F04C18/02
Filed: 1992-03-04
Granted: 1997-03-18
Abstract: In a scroll type compressor, a movable scroll is engaged with an immovable scroll so that spaces are formed for taking in a fluid including a lubricating oil mist to be compressed.  The movable scroll is revolved around a central axis of the immovable scroll so that, as the spaces are displaced toward a center of the immovable scroll, a volume thereof is reduced to compress the fluid therein.  The immovable scroll has a passage through which each of the spaces is communicated with a discharge chamber upon reaching the center, whereby the compressed fluid is successively discharged through the passage into the chamber.  An oil-separating plate is disposed in the chamber at a given level lower than the passage, and a reed valve is provided at the passage.  A retainer for the reed valve is shaped such that the compressed fluid discharged from the passage through the reed valve is directed to and impinged on an upper surface of the plate, to thereby separate a lubricating oil from fluid, whereby the separated oil is reserved in a lower portion of the chamber defined by the plate, and thus a level of the reserved oil is maintained at the upper surface thereof.
