摘要:
An ocular fundus portion analyzer and the method are provided for attaining accurate and quick detection and diagnoses of an ocular fundus defect portion, such as an excavation of an optic disk caused by glaucoma and a macula retinae caused by retinal detachment, by dealing with a large number of single-shot ocular fundus images, for example, taken in physical examinations. It is configured to include an image importing portion for importing an image of an ocular fundus portion taken by a visible radiation or a near-infrared radiation; a pixel data generation portion for generating pixel data including pixel positions and luminance of pixels constituting the image; a local plane gradient image generation portion for generating a three-dimensional image from pixel positions and luminance of the pixel data, obtaining a local approximation plane at any pixel and generating a local plane gradient image from a gradient angle with respect to a control plane of the three-dimensional image; and a display portion for displaying the local plane gradient image.

摘要:
A casing and a lid which are supplied to a casing/lid supply machine are fed to a main assembly line where a light-shielding sheet is mounted on the casing and a film cover supplied from a film cover assembly line is mounted in the casing. Pressers supplied from a presser assembly line are mounted on the lid. The casing and the lid are combined with each other, completing a film case. The film case manufacturing system is capable of efficiently manufacturing highly accurate film cases and is relatively compact in structure.

摘要:
A high temperature (1000.degree. C. or higher) gas distributor for a fluidized bed, which comprises a pair of refractory supporting bricks which are each provided with grooves at given intervals and which are positioned with a space therebetween in such a manner that the grooves face each other; plates made of electrocast zirconia brick, both ends of which are inserted into the respective grooves of opposing supporting bricks and are secured therein by mortar; and refractory holding bricks for holding the refractory supporting bricks and the ends of the plates in relative position.
摘要:
A high temperature (1000.degree. C. or higher) gas distributor for a fluidized bed, comprising a plurality of plates which are made of an oxide-based burned refractory material and which are reduced in thickness in the longitudinal direction thereof leaving both sides thicker, refractory supporting bricks holding in position both sides of the plates, and refractory holding bricks holding in position the above refractory supporting bricks and the ends of the plates.
摘要:
A process for controlling the coke balance as well as the size of coke particles within a fluidized bed in the range adapted for continuous operation of a heavy residual oil cracking apparatus, wherein thermal cracking of heavy residual oil is performed under fluidization of coke particles and steam, which comprises classifying one portion of the coke particles withdrawn from the fluidized bed into coarse particles and fine particles by means of a pneumatic classifier, and after the size of said coarse particles have been reduced by combustion, returning them to the fluidized bed along with said fine particles.
