Title: Fluiding bed type dust collector for blast furnace waste gas
Inventor: SUGAWARA TAKAYUKI
IPC: B01D46/34
Filed: 1980-02-23
Abstract: PURPOSE: To increase filtering area per tank and raise the performances of cleaning and treatment by using a structure in which the inside of a tank is divided in a lattice form to form a double filtering layer and the primary filtering layer and the secondary filtering layer are mutually surrounded by each other.  
     CONSTITUTION: Tower top waste gas is supplied through an inlet 10 into the conical portion 1a of a tank 1 and then directed through each inlet 16 into the primary filtering layer chamber 3 opening in the conical portion 1a. The incoming waste gas flows out in four ways through a souble filtering layer 5 provided on each side of the primary filtering layer chamber 3 to the surrounding secondary filtering layer chamber 4 whose pressure is lower than that of the primary filtering layer chamber 3. Clean gas coming into the secondary filtering layer chamber 4 goes up in the chamber and then is collected through a conduit 11 into a clean gas supply pipe 17 outside the tank.

Title: Gamma camera
Inventor: KANEDA AKIYOSHI
IPC: G01T1/164
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To make automatizable the body motion correction by acquiring a subject image and an image for body motion correction with different cameras, obtaining body motion quantity from a body motion parameter obtained from the image for body motion correction and correcting the subject image. SOLUTION: A buffer 3 for gamma camera image collection collects and holds the gamma camera image of a subject P imaged by a gamma camera 1 and a buffer 4 for infrared image collection collects and holds infrared image of the subject P formed by an infrared camera 2. Based on an infrared image, a center-of-gravity calculator 5 calculates the position of the center of gravity of the subject P as a body motion parameter. This threshold is judged in a threshold judgment part 6. When it is within a threshold value, the gamma camera image data is added to an initial image data in an image adder 8. When it exceeds the threshold value, an image corrector 7 shifts the image data to the opposite direction to the motion of the center of gravity and the image adder 8 adds this to the initial image data.
