Abstract: PURPOSE:To enable safe disposal by agitating a sludge in a long-term storage tank to make it a slurry, sending a liquid feed tank after taking it out of the tank and making it a uniform cement solidified body along with measuring, regulating and controlling radiation concentration thereof during the predetermined processes. CONSTITUTION:A sludge in a long-term storage tank 1 is agitated by a submerged agitating pump 2, is taken out using a taking-out nozzle 3 to be recycled and is sent to a day tank 6 along with watching a radiation monitor 4 and opening a liquid feed valve 5, when radioactivity reaches a certain level. At the tank 6, the sludge is uniformly agitated by an agitator 7 and, when a value of a radiation monitor 8 is high, concentration thereof is regulated through calculation of dilution factor derived from water pouring by a water pouring valve 9 and a partial returning by a returning line 10. In case the concentration is too low, the concentration regulated by stop and operation of the agitator 7, and sedimentation, is confirmed by the monitor 8, and then is homogenized. After that, the sludge is recycled to a recycle line 13 by a slurry pump 12 and the concentration is conformed by the monitor 8, and then cement is supplied from a cement feeder 23 to produce a uniform cement solidified body. In this way, the solidified body can be safely disposed.

Title: Method for inspecting pinhole
Inventor: YOSHIDA TAKAO
IPC: G01M3/16
Filed: 1989-12-20
Abstract: PURPOSE:To easily detect a pinhole which links partitioned chambers in a liquid containing container with high accuracy by applying a voltage or current to liquid charged in one chamber through the container wall of one chamber and measuring electric variation generated in the liquid in the other chamber through the container wall of the other chamber. CONSTITUTION:When a plastic plate 22 charged electrostatically is put close to the liquid 61 charged in a chamber 6 of the container 1 across the container wall 21, charges 23 having the opposite polarity from static electricity accumulated in the plate 22 gather to the side of the liquid 61 which faces the plate 22 and charges 24 having the same polarity like to leave as much as possible. When there is no pinhole between the chamber 6 and a chamber 7, the charges 24 only migrate to the opposite side and the liquid body has no change, so a voltage detector 26 which is put close to the chamber 7 does not generate any change. If there is the pinhole 25 which links the chambers, the charges 24 migrate into the chamber 7 through the pinhole 25 and a voltage is developed in the liquid body 71. Then the static electricity detecting aluminum foil 27 of the voltage detector 26 put close to the chamber 7 is opened and the presence of the pinhole 25 is detected.

Title: Method and instrument for measuring property or characteristics of material by using changing electromagnetic field
Inventor: JIYOFUREI MAYO
IPC: G01R27/26
Filed: 1989-12-20
Abstract: PURPOSE: To accurately measure the property or characteristics of a nonmetallic material, especially, foodstuff by positioning a sensing coil near an electromagnetic field which changes with time and detect the signal which is generated when a nonmagnetic material is introduced to the electromagnetic field. CONSTITUTION: A transmission coil 1 is connected to an RF(radio frequency) source 2 and the primary coil of the RF source 2 generates a periodically changing electromagnetic field when a selected frequency is supplied. A reception (secondary) coil 3 is placed near the transmission coil 1 and the coils 1 and 3 are arranged so as to surround a material passed through the coils 1 and 3. Another secondary coil 4 is formed to have a number of turns which is twice as large as that of the coil 3 and an area which is about 1/5 of that of the coil 3 and positioned so that the coil 4 does not surround the passing material. When a relatively conductive material passes through the coils 1 and 3, an overcurrent is generated in the material and induces a signal in the coil 3.  In order to induce the signal in the coil 3 when the material exists in the electromagnetic field, it is necessary to supply a frequency that generates the electromagnetic field which gives a distinguishable change to the invalid part of the signal from the RF source 2 after selection.
