Abstract: PROBLEM TO BE SOLVED: To remove substances on a water surface without scattering them by holding the insides of an intermediate cylinder and an external cylinder under negative pressure, sucking the water surface to be decontaminated to their tips, and generating an air flow from the inside of the intermediate cylinder to the inside of the external cylinder. SOLUTION: The tip of the external cylinder 24 is made to abut against the wall surface 21 of a nuclear reactor container 2 filled with water and a suction device 33 is placed in operation to reduce the pressure in the external cylinder 24, and air is sent from an air sending device 30 to the inside of the intermediate cylinder 22. At this time, the quantity of suction is made larger than the quantity of air sending to hold the insides of the intermediate cylinder 22 and external cylinder 24 under negative pressure, thereby bringing the tips of the intermediate cylinder 22 and external cylinder 24 into contact with the wall surface 21. After the water in the external cylinder 24 is discharged, air flows are generated from an air sending pipe 29 to a suction pipe 31 through the inside of the intermediate cylinder 22 and the space at the outer periphery of the external cylinder 24.  The substances sticking on the wall surface 21 are broken and peeled, but the tips of the intermediate cylinder 22 and external cylinder 24 are in contact with the wall surface 21, so they are never scattered into the pressure container 2. Further, the peeled substances are carried to a filter 32 with the air flowing in the suction pipe 31.

Filed: 1992-05-06
Abstract: PURPOSE:To provide a root extracting arithmetic unit which never deteriorates its performance even though the hardware scale of a multiplier is reduced. CONSTITUTION:A remainder holding means 10 uses the higher order of an operand normalized every two bits outputted from a normalizing means 7 as an address and retrieves an approximate reciprocal of the square root through a table information storing means 8 to define the 0-th remainder as a normalized operand. Then, the output of the means 10 is multiplied by the approximate reciprocal of the square root through a multiplication means 11. Thus, a partial square root is obtained. The partial square root of each repetition are merged together by a digit matching means 20 and an addition means 21. Then, the remainder of the next step of the repetitive calculation is obtained when the product of the merged square root and the partial square root is subtracted from the remainder by an inverting means 15, a multiplicand generating means 16, and a (R+SXT) arithmetic means 17. Furthermore, the output of the means 11 is rounded at the position smaller than the least significant bit of the partial square root by one bit.

Abstract: PURPOSE:To conduct detection of high accuracy and to perform etching with excellent flatness, by detecting the point of completion of etching according to a variation in the intensity of a reflected light which appears corresponding to a variation in the height of a stepped portion formed by etching and to an angle of inclination on the lateral side of the stepped portion. CONSTITUTION:A laser beam Li is applied from the lateral side of a substrate 4 at an angle of about 5 degrees to the surface of the substrate 4. A reflected light Lr is made to enter a photodetector 11 through a condenser lens 9 and an optical filter 10 and converted into an electric signal corresponding to the intensity thereof, and the signal is inputted to a signal recording device 12. The intensity R of the reflected light Lr is monitored continuously by the device 12. An intensity P at a starting time point S rises first sequentially and generally, then a change appears in the state of its rising, and subsequently the intensity increases sharply up to a prescribed level. An etching process is ended at a time point E whereat the prescribed intensity is reached. By this method, detection of high accuracy is implemented, and etching is performed with excellent flatness.
