Title: Data compression method and circuit for restoring compressed code
Inventor: MASUDA KAZUYA
IPC: G06K15/02
Filed: 1995-05-31
Abstract: PURPOSE: To raise the compression rate of a compression code in the Huffman compression method by sampling character font data in the unit of four bits as the compression bit width to compress the data. CONSTITUTION: Character font data 9 expresses various characters by font data indicating white or black in each of squares in 40 rows and 40 columns. In the data compression method, the compression bit width for data compression of each font data of character font data 9 is set to four bits as the bit width of bit strings 9a. Since the bit width of bit strings 9a for compression is set to four bits in this manner, there are 16 kinds of bit strings 9a of character font data 9 to be compressed. Since one kind of the bit string 9a occurs concentratedly with respect to frequencies in occurrence of bit strings 9a, bit strings 9a in the unit of four bits have a form most suitable for high compression.

Abstract: PURPOSE:To reduce thermal stress produced due to the accumulation phenomenon of liquefied sodium in a piping which is used in the primary or secondary system of a fast breeder reactor by longitudinally installing inside the piping helical partition sheets which are the means of mixing coolant at a uniform ratio. CONSTITUTION:Two partition sheets 12 and 13 which provide two current passages separated from each other are disposed inside a piping 11 in the longitudinal direction thereof as to have the end parts of both the sheets intersecting each other. Both the partition sheets 12 and 13 are twisted 90 deg. clockwise from the respective inlets to the respective outlets and arranged in series with each other as to have the longitudinal directions of their inlet-side end faces coincide with the perpendicular direction. Sodiums 9a and 9b having high and low temperatures are mixed at a uniform rate by means of both the partition sheets 12 and 13 to create other sodium layer having a medium temperature, on account of which the liquefied sodium flows in the phases of three layers 9a to 9c inside the piping 11. Differences in temperature between adjacent layers of the liquified sodium therefore become unnoticeable so that thermal stress may be reduced.
