Title: Solvent fractionation of heavy oil
Inventor: UEDA TAKASHI
IPC: G01N33/28
Filed: 1984-03-01
Abstract: PURPOSE:To perform solvent fractionation of heavy oil with minimized analysis error even on a small amt. of specimen, by treating the heavy oil with a solvent with high solvency power and a solvent with low solvency power. CONSTITUTION:A heavy oil (liquefied coal, residual oil of vacuum distillation, residual oil of normal pressure distillation, etc.) is dissolved in a solvent with high solvency power (e.g. quinoline, pyridine or tetrahydrofuran) under stirring. The soln. is condensed to such an extent that the solvent may be present in an amt. 0.5-2 times as much as heavy oil. Then a solvent having low solvency power (e.g. benzene, toluene or n-hexane) is added in an amt. about 20-30 times as much as heavy oil by weight. After agitation, solvent insolubles are made to settle down. The soln. is left at rest and insoluble components are filtered out by means of a glass filter, etc., followed by drying and weighing. Heavy oil can be fractionated into various components by varying combination of the two types of solvents.

Abstract: PURPOSE:To control tensio in such a position where a spread quantity control mechanism and the like required for unifying tension is installed by providing a control means for a shaft moving means to control the shaft moving means, so that a moving shaft may be always positioned in a range where the movement of a moving shaft is not obstructed by means of a fixed shaft. CONSTITUTION:When tension (t) becomes very large, force is out of balance, a moving shaft 2 is pushed down, and the distance between the range finder 16 on the lower face of a fixed shaft 1 and the metallic piece 17 of the moving shaft 2, namely output of the range finder 16 is increased. Because a distance measured value is more than a target value, in a distance control 19 control output is increased. Namely the target value of an air controller 13 is increased, and the air controller 13 controls a pressure control valve 15 so as to conform an air pressure measured value to its target value. As the result, the air pressure of an air cylinder 3 is increased, a rotor 4 and the moving shaft 2 are pushed up by means of the air cylinder 3, and the distance betwee the fixed shaft 1 and the moving shaft 2 reaches its target value so as to be stabilized. Consequently control in response to tension variation can be performed.

Abstract: PURPOSE: To provide a closed safe injector having a pull back two heads needle by inclining, bending, surrounding, and closing an inner side needle of a carrier by an outer sleeve 2 in the position where the needle is withdrawn in the outer sleeve. CONSTITUTION: A needle 8 communicates with a blood-collecting vessel in an outer sleeve 2, and a position control button 28 is formed protrudingly from a needle carrier 18 on the outer sleeve 2 so as to slide via a guide groove extending in the axial direction. After a blood sample is obtained by thrusting a vein of a patient, the needle 8 is transferred to the withdrawn position where the needle is closed by the outer sleeve 2. As the needle carrier 18 moves in a proximal direction via the outer sleeve 2, the distal end part of the needle carrier 18 which holds the needle 8 is forced to rotate and the needle 8 is inclined and bent toward the outer sleeve 2. Consequently, reusing of the needle 8 is prevented and the danger of thrusting a needle accidentally into a medical worker can be avoided and the injector 1 is disposed safely.

Abstract: PURPOSE:To compensate the dark fringe part of an image and to improve resolution by forming such a deformed raster with a projecting part that the periferal part of the image is enlarged more than its center part and correcting the deformed raster with an optical system from a projecting lens to a screen to recover an original raster shape. CONSTITUTION:For example, as for a G projecting tube arranged at the center, such a raster 6 is formed that its peripheral part is enlarged more than the original raster shape 5. Thus deformed raster is corrected by the optical system extending from the projecting lens 2 to the screen 4 to recover the original raster shape, which is projected on the screen 4. Namely, by reducing the size of the peripheral part through the use of a concave mirror for a mirror 7, the image is recovered to the original shape and size. At this time, the enlarged part is reduced in size. Thus, the light quantity of the peripheral part is increased, brightness is improved and also the resolution is improved.
