Title: Deashing transportation of coal slurry
Inventor: ONIZUKA SHIGENORI
IPC: C10L9/00
Filed: 1982-02-17
Abstract: PURPOSE:To enable reduction in the ash content of coal and removal of rust and scale formed on an internal surface of pipe as well as long-distance transportation of coal, by dispersing ash-containing pulverized coal in an aqueous solution of a specified deashing agent to prepare pulverized coal slurry. CONSTITUTION:Ash-containing coal is pulverized. Separately, an aqueous solution of a deashing agent is prepared by mixing acidic ammonium fluoride with an aqueous solution of hydrochloric or citric acid containing a corrosion inhibitor in a tank 1. The obtained deashing agent is mixed with the pulverized coal and water in a tank 2 to prepare pulverized coal slurry, which is then pumped to a destination through a long-distance transportation pipe 4 using a pump 3. During the transportation, the ash is dissolved by the deashing agent and iron rust with the pipe 4 is dissolved and removed. The coal slurry is taken out of the terminal of the pipe 4 and separated into deashed pulverized coal and the aqueous solution in the first dehydrator 5. The pulverized coal is washed in a washing tank 6, dehydrated in the second dehydrator 7 and, if necessary, dried in  a dryer 8 to give finished deashed pulverized coal.

Abstract: PROBLEM TO BE SOLVED: To improve position detection precision and to reduce the cost. SOLUTION: An operation part calculates declination ϕ against the Y-axis (Yv ) of an absolute coordinate system from the distances d1 and d2 of reflectors A and B, which are measured by a laser distance laser, the positions P1 (x1 , y1 ) and P2 (x2 , y2 ) of the operation coordinate system at that time, travel azimuth angles ϕ1 and ϕ2 against the y-axis (yv ) of the operation coordinate system and the coordinates (XA, YA) and (XB, YB) of the reflectors A and B. Furthermore, the absolute coordinate (X2 , Y2 ) of a position P2 is calculated. Then, P2 (x2 , y2 ) of the operation coordinate system containing an estimation error is corrected to the absolute coordinate (X2 , Y2 ) and the estimation error is removed. Thus, position precision improves. Since only one expensive laser distance sensor is required and the cost is low.

Abstract: PURPOSE:To prevent the depressing operation of a shake correction executing switch from becoming the cause of camera shake by arranging the shake correction executing switch so that it may be positioned on an opposite side to a release button by putting a photographing lens between them. CONSTITUTION:A switch button 101 (shake correction selecting switch) which can be externally operated constitutes a switch SW3 and is a self-reset type switch where the switch SW3 is turned on while the button 101 is operated to be depressed and it is turned off when the button 101 is released. When the switch SW3 is turned on, a shake correction means 11 is driven based on detection output from a shake amount detection means 1. In such a case, since the button 101 is a switch button constituting the shake correction selecting switch SW3 and is arranged on the opposite side to the release button 100 by putting the photographing lens between them, a camera must be necessarily held with both hands in the case of operating the button 101, whereby the camera shake caused with stopping the shake correcting operation is extremely restrained.
