Title: Supply discharge damper for powder
Inventor: YAGI MASAHIRO
IPC: B65G65/40
Filed: 1989-09-07
Abstract: PURPOSE:To prevent leakage of powder from between a side wall or the like and the bottom by providing at a lower part inside side walls a plate which, when the damper closes, functions as a seal by contact with the bottom. CONSTITUTION:An supply-discharge damper has side walls 3 in the form of a box and two bottoms 1, 1 which freely perform the opening and closing. The transversely cutaway section of each of the bottoms 1, 1 forms as arc having a horizontal axis, and the rotational axis 2 for the opening and closing, extending in parallel with the axis of the arc, is at an eccentric position shifted from the axis of the arc at the time of the closure toward the direction of the opening turn. At a lower position inside the side walls 3 there is provided a plate 6 which, when the damper closes, functions as a seal by contact with the bottoms. This constitution prevents leakage at the time of the closure even when particulates with minor particle diameters are handled.

Abstract: PROBLEM TO BE SOLVED: To continuously measure a hold amount of sludge in a reaction tank, etc., by picking up images of a state of a sludge in the tank, recognizing an interface of the sludge, processing obtained image signals and operating a concentration of the sludge. SOLUTION: A measuring apparatus for a hold amount of a sludge of a reaction tank 1 processing, e.g. anaerobes has an image pickup part 8 moving up and down and picking up images of the sludge, a position-measuring part 9 measuring a position of the sludge, and an operating part 10 operating a hold amount of the sludge from signals of the pickup part and measuring part. For instance, the image pickup part 8 is sunk to a bottom part 1a of the reaction tank 1 and then pulled up in a sludge phase 3. An image of an area to be measured of the sludge phase 3 is input to the operating part 10, whereby sizes of the sludge distributed in the phase are wholly measured. A concentration of the sludge at each position is calculated in a predetermined method from a measured value of a particle diameter of the sludge and a VSS per unit volume of the sludge analyzed beforehand.  A height of the sludge phase 3 is obtained from an image signal when the image pickup part 8 crosses an interface 5 of the sludge. The hold amount of the sludge is operated accordingly.

Title: Measurement output recorder
Inventor: FUKUMA TOSHIAKI
IPC: G01N21/27
Filed: 1986-09-30
Abstract: PURPOSE:To enable highly accurate measurement and recording at peak value with a relatively small capacity memory, by a method wherein a measuring output sampling interval is widened while hourly rate of change is small and it is narrowed while the rate is large. CONSTITUTION:When the sampling interval Po is wide, it is determined whether a difference between the current sampling data and the preceding sampling data is larger than a first reference DELTAA1 or not and when the difference is smaller than the DELTAA1, the subsequent sampling pitch is set for Po to start the subsequent operation from the first step. Then, when the rate of change is large, the subsequent sampling interval is set to P=Po/10 to determine whether the peak of a measuring output is exceeded or not. When the peak is not exceeded, the sampling interval P is set subsequently. When the exceeding of the peak of a measuring output is found, jndgement is made on whether the variation of a measured value is smaller than the second reference DELTAA2 and when it is smaller, the sampling interval is put back to Po. This enables highly accurate measurement and recording at peak value with a relatively small capacity memory.
