Title: Method for reusing liquid phase oxidizing catalyst
Inventor: HASEBE REN
IPC: C07C51/265
Filed: 1992-01-10
Abstract: PURPOSE:To efficiently and inexpensively produce aromatic carboxylic acid by concentrating a liquid obtained by separating aromatic carboxylic acid from a reactional product and adding water to the obtained concentrate to precipitate and separate a byproduct containing a reaction intermediate and a reaction inhibitor to obtain a catalyst-containing solution and reusing this solution. CONSTITUTION:A mono- or di-substituted aromatic compound represented by formula I or II (wherein R1 and R2 are hydrogen, a methyl group, an ethyl group, an isopropyl group or an acyl group and do not take hydrogen at the same time) is subjected to liquid phase oxidation in a 2-4C lower aliphatic monocarboxylic acid solvent solution in the presence of a catalyst consisting of a heavy metal and bromine using molecular oxygen or molecular oxygen- containing gas to obtain a reactional product. Aromatic carboxylic acid is separated from the reactional product and the catalyst in the obtained separated solution is reused. At this time, the separated solution is concentrated and water is added to the obtained concentrate to precipitate and separate a reaction intermediate and a byproduct to obtain a catalyst-containing solution which is, in turn, used as a liquid phase oxidizing catalyst.

Abstract: PURPOSE:To provide a pseudo gradation device improving an output picture in response to a feature of an input picture. CONSTITUTION:A threshold level matrix storage means 10 stores plural threshold matrices. An inference means 12 infers a feature of the lightness depending on a change in the lightness being a factor of the structure of the picture elements or a dispersion in the lightness. A selection means 14 selects a threshold level matrix stored in the threshold level matrix storage means 10 based on the feature of the lightness inferred by the inference means 12. Thus, pseudo gradation in response to the feature of an input picture is implemented.

Title: Pulse doppler radar equipment
Inventor: YASUFUKU MASAKI
IPC: G01S13/532
Filed: 1984-01-09
Abstract: PURPOSE:To enable the removal of mutually interfered waves without removing the true target by mistake by cutting outputs when a signal of the same amplitude exists at equal range gate intervals. CONSTITUTION:Amplitude comparison circuits 7 compare signals corresponding to range gates and send signals to ON/OFF circuits 8 to cut the outputs of band pass filters 6 when a signal of the same amplitude exists at equal range gage intervals. Otherwise, the ON/OFF circuit 8 is turned ON to allow the outputting from the band pass filters 6 as intact. In the case of mutual interference, outputs of the band pass filters 6 corresponding to the Doppler frequency of interfered waves are cut to remove the interfered waves. Thus, the true target is hardly removed taken for mutually interfered waves.
