Abstract: PURPOSE: To provide a method and device for curved surface image input which can stably input the two-dimensional image of an object from a certain position with simple constitution even if the curved surface of the object is roughly positioned or without determining an image input start position. CONSTITUTION: A line sensor camera 2 rotates the object 1 on a rotary stage 3 along a certain distance to the curved surface of the object 1, and then a two-dimensional image is obtained by the linear scanning and rotary movement subscanning of the line sensor camera 2.

Title: Dispersing mechanism of three-phase fluidized reactor
Inventor: MAKINO SHIGEO
IPC: B01J8/22
Filed: 1985-07-03
Abstract: PURPOSE:To enhance the contact efficiency of gas-liquid-solid, by covering the under surface of the outer edge of the downward dish shaped cap fixed to the upper end of a dispersing cylinder with the thin disc shaped plate having elasticity engaged with and fixed to the dispersing cylinder at a position lower than the outflow port of said cylinder. CONSTITUTION:The gas-liquid mixed phase fluid flowed in a dispersing cap 9 pushes down a plate 8 as shown by a dotted line by the pressure of said fluid to be injected from the gap between the dispersing cap 9 and the plate 8. This gap is forcibly widened on the basis of an angle theta and becomes large toward the outside and enhances the dispersing effect when the fluid is injected. Because the plate 8 has elasticity, said plate 8 vibrates when the gas-liquid mixed phase fluid is injected to be finely divided and gas is formed into fine bubbles. When no fluid is injected, the plate 8 is contacted with the cap 9 and, therefore, a solid particle such as a catalyst is prevented from penetrating in a mixed bed 5 from a dispersing cylinder 4.
