Title: Low-temperature separation of thermally cracked hydrocarbons
Inventor: YOKOBORI YOSHINORI
IPC: C07C7/09
Filed: 1984-09-13
Abstract: PURPOSE:Thermally cracked hydrocarbon is separated into the demethanator feed and light gas and the methane fractions from both feeds are combined to give the condensed methane fraction, which is fed to the demethanator to recover ethylene fraction in the methane fraction. CONSTITUTION:Thermally cracked hydrocarbon gas is pressurized, cooled down in color E1, and the condensed ethylene fraction is introduced into the feed tank D1 for the demethanator and the uncondensed gas is cooled in coolers E2 and E3 to condense ethylene and thane, which are sent to ethylene separation tank D2. The light gas from tank D2 is sent to the second step and the condensed liquid is used as a coolant, then sent to tank D1. The condensed liquid of ethylene fraction from tank D1 is sent to the demethanator column T1 to take ethylene fraction of the bottom and take methane fraction out of the column top and uncondensed methane is sent to the second step. The light gas from tank 2 is separated by means of coolers E5, E6 and separation tanks D3 and D4 into hydrogen and condensed methane and the hydrogen is recovered 25. The methane from the third step is cooled with cooler E4 and the condensed methane is combined and sent to separation tank D5 where uncondensed fraction is recovered 26 and the condensed fraction is sent to the demethanator T1.

Title: Optical information recording medium
Inventor: ARIGA SHUJI
IPC: G11B7/246
Filed: 1984-09-13
Abstract: PURPOSE:To shut off impurities to accelerate the color fading of a dye, above all, the permeation of moisture by forming a transparent inorg. oxide film on an optical recording layer by a low-temp. physical vapor deposition method and to maintain a good dye characteristic for the longer period of time by maintaining an atmosphere in which the color fading of the die arises hardly. CONSTITUTION:The inside of an org. dye layer can be confined into an oxidizing atmosphere by forming a transparent inorg. oxide film on the org. dye layer or the high-polymer film contg. the org. dye by the low-temp. physical vapor deposition method. Such a dye which has the intermolecular cation in the molecu lar skeleton of the org. dye induces usually color fading when reduced by light but the color fading by the photoreduction can be substantially eliminated by main- taining the dye layer in the oxidizing atmosphere by forming the inorg. oxide film. The temp. in the stage of forming the film is desired at <=300 deg.C in order to confine the dye layer into the oxidation atmosphere by forming the more active oxide film. However, the dye itself deteriorates thermal ly at >=250 deg.C. The film forming temp. is therefore restricted to <=250 deg.C.

Title: Color converting data preparing method and color converter using the same
Inventor: SHIMAZAKI OSAMU
IPC: H04N1/00
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To shorten time required for preparing color converting data by finding converting characteristics for converting color image data C, M, Y and K for color image data C', M', Y' and K' while using the specified relation of color image data C, M and Y with the color image data K. SOLUTION: A color printer 18 sets the color converting data for obtaining color print proof image A5 for highly accurately predicting a color printed matter A4 while using a test chart T1 prepared by a color printer 17 and a test chart T2 prepared by the printer 18 itself. These color converting data independently find color converting data for converting the color image data C, M and Y to C', M' and Y' and converting the color image data K to K' while using the relation expression of K=f(C, M, Y). Thus, the time required for preparing the color converting data can be remarkably shortened and since the amount of color converting data is made irreducibly minimum, storage capacity can be decreased.
