Title: Production of carbon cluster c60
Inventor: YOSHIDA YOSHITAKA
IPC: B01D15/08
Filed: 1992-01-14
Abstract: PURPOSE:To obtain a carbon cluster C60 of improved purity by separating carbon cluster C60 through liquid column chromatography from a carbon cluster mixture obtained by extracting soot in an exhaust gas from an internal combustion engine with an aromatic hydrocarbon. CONSTITUTION:A fuel such as gasoline is burned in the cylinder of an internal combustion engine and soot is collected from the exhaust gas from an exhaust vent. The soot is then extracted with an aromatic hydrocarbon such as benzene using a Soxhlet extractor to obtain a carbon cluster mixture whose content is 0.1-5wt.% in the soot. On subjecting the mixture to mass spectroscopy, carbon cluster (hereafter, referred to as fullerene) C60 and fullerene C70 can be recognized at mass/charge of 720 and 840, respectively. The mixture is then developed with e.g. hexane using liquid column chromatography packed with neutral Al2O3 as absorbent to obtain a hexane solution of fullerene C60 followed by evaporating the hexane, thus obtaining the objective high-purity fullerene C60.

Title: Thermal transfer gradation recording
Inventor: DOI ATSUHIRO
IPC: B41J2/36
Filed: 1986-01-17
Abstract: PURPOSE:To make it possible to moderate the variations in the optical density of an image output with applied energy and to easily output gradations, by recording gradations through a construction wherein each heat generating resistor has a thermal output distribution in the area of a picture element. CONSTITUTION:A thermal head 1 comprises heat generating resistors 31-3n respectively in picture element regions 11-1n, the area of each of the resistors being about 1/2 times the area of each of the picture element regions, so that a temperature distribution is generated when energy is applied, and the temperature distribution of the heat generating resistor in one picture element does not overlaps with those in the adjacent picture elements. When energy, or an electric current, is applied to each of the heat generating resistors 31-3n, the image output density D of each of the picture element is not affected by those of the adjacent picture elements. Accordingly, since the area of the heat generating element or a piece of material provided in proximity thereto is set to be smaller than the area of the picture element, or is divided into areas smaller than the are of the picture element, or current distribution is generated, the variations in optical density with the applied energy can be moderated, and gradations can be easily outputted.
