Title: Adjustment for dot form position deviation by pixel information not forming dot
Inventor: KANETANI MUNEHIDE
IPC: B41J2/51
Filed: 2000-03-01
Abstract: PROBLEM TO BE SOLVED: To reduce a positional deviation of dots in a main scanning direction and improve an image quality by forming images with the use of delay data for compensating for a difference of arrival times to pixels of each nozzle array in a main scan in addition to image pixel value data for forming dots to each pixel. SOLUTION: A printer 22 main scans to relatively reciprocate a printing head 28 to a printing medium, and at the same time, sub scans to send the printing medium in a sub scanning direction. During the time, the printer drives the printing head 28 according to printing data thereby forming dots on at least part of a plurality of pixels arranged in a direction of the main scan. At this time, when dots are formed, image pixel value data showing a dot form state in image pixels and delay data showing a delay amount for compensating for a difference of arrival times to pixels in the main scan in accordance with a distance between nozzle arrays set via a predetermined interval in the main scanning direction are used to compensate for a deviation of a dot form position of each nozzle in the main scanning direction.

Title: Process and apparatus for separating and recovering aromatic component from liquid oil
Inventor: TAKINO YOSHIHIDE
IPC: B01D17/00
Filed: 2000-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a process for separating and recovering aromatic hydrocarbon compounds such as polycyclic aromatics from a liquid oil at a low energy consumption and a low cost without the necessity for high temperatures, high pressures, and an expensive catalyst and without producing a large quantity of carbon dioxide. SOLUTION: This process comprises adding a nucleophilic reagent such as an alcoholic solvent or water to a liquid oil to enhance the selectivity of the solvent for the organosulfur compounds because of attention paid to the fact that an aromatic hydrocarbon has powerful electron-donating properties, that organosulfur compounds themselves have aromatic rings, and that the divalent lone electron pair on the sulfur atom has powerful electron-donating properties and the aromatic hydrocarbon compounds; separating the mixture of the organosulfur compounds having more powerful electron-donating properties with the aromatic hydrocarbon compounds from the liquid oil; adding a highly electron-donating solvent to the mixture to thereby separate and recover the organosulfur compounds from the aromatic hydrocarbon compounds in virtue of the difference between their electron donating properties.

Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a charged particle beam lithography system which can plot a pattern with high accuracy without interrupting the light or laser beam used for measuring the height fluctuation of a sample, by preventing a charge-up phenomenon due to scattered electrons on the end face of the sample at the time of plotting the pattern by using a charged particle beam.

At the time of plotting the pattern, a scattered electron interrupting plate 2a is set up for interrupting charged particles scattered on the surface of the sample 1 and in the lithography system in such a way that the height of the top face of the plate 2a becomes equal to or slightly higher than the surface 11 of the sample 1. Consequently, the accuracy of plotting positions in the peripheral area of the sample 1 can be improved, because the plate 2a does not interrupt the light or laser beam emitted from a light source 5 for measuring the height of the sample 1.
