摘要： PROBLEM TO BE SOLVED: To provide a method for locating a metal touch portion when a buried metal tube is in metal-touch with another metal tube buried in parallel therewith. SOLUTION: This method is for detecting the metal touch portion of the buried metal tube with an anticorrosive coating with the other metal tube close-buried in parallel therewith. AC signals of different frequencies are applied to the buried metal tube and to the ground from both the sides of an objective zone of detection. The intensity of a magnetic field is measured by moving magnetometric sensors disposed on a ground surface to each of measurement points placed at prescribed intervals in the extension direction of the buried metal tube while scanning in the orthogonal direction. By signal-processing obtained data, changes in the intensity of the magnetic field are compared with each other at respective measurement points corresponding to the signals of different frequencies, thereby determining whether there is a metal touch portion, and its location.

摘要： PURPOSE: To smoothly execute the change-over of blowing tanks while holding the balance of blowing flow rate by gradually closing a blowing control value for a blowing tank to a regulating opening degree at the time of judging the completion of blowing and at the same time, gradually opening a control value for a blowing tank under waiting to a regulating opening degree. CONSTITUTION: The blowing from the blowing tank 1-1 processes and the weighing value from a weighing device 3-1 becomes the regulating value or lower, and at the time of judging the completion of blowing the blowing control value 7B-1 is gradually closed to the regulated opening degree with a flow rate controller 6-1. Further, a cutoff valve 2A-2 is opened and the blowing control valve 7B-2 is gradually opened according to the blowing flow rate with a flow rate controller 6-2. At this time, since the blowing tans 1-1, 1-2 are controlled to almost the same pressure, the pressure variation in the blowing tanks and a carrying pipe 8 and the blowing flow rate variation caused by the start of closing the blowing control valve 7B-1 and the start of opening the blowing control valve 7B-2 are made to the min. limit. Successively, a blowing cutoff valve 2A-1 and the blowing control valve 7B-1 are fully closed and the blowing cutoff valve 2A-2 and the blowing control valve 7B-2 are fully opened.

摘要： PURPOSE:To enable uniform treatment on a large area substrate in the radial direction in a plasma treatment using microwave. CONSTITUTION:A face H in section extending between a connection part with a microwave waveguide 3 and a connection part with a plasma generation chamber 1 is gradually changed so as to have a diameter, a part of a radius or all of the radius, and at least one of the face E is changed from a circular arc to a circle, whereby a mode transducing waveguide 10 is formed. At least such a microwave waveguide 10 is provided. With such a microwave waveguide 10 a large diameter microwave waveguide is formed so that uniform microwave of large area plane wave can be supplied to the plasma chamber. It is thus possible to perform uniform and large area treatment at the time of plasma treatment of sputtering, CVD, etching and the like.

摘要： PROBLEM TO BE SOLVED: To recover highly stable steam by suppressing a thermal change incidental to a change in the inventory in a prechamber of a dry coke quencher into which red-hot coke is simultaneously introduced from two batteries of coke ovens and improving the efficiency of heat recovery. SOLUTION: In a dry coke quencher wherein red-hot coke pushed out of two large and small coke ovens of different capacities is fed into a prechamber, then cooled with a recirculating gas at the cooling chamber under the prechamber to recover the heat, and discharged from the lower discharge device. The amount of the coke present in the prechamber is monitored, and the amount of the coke discharged from the coke discharge device is controlled so that this amount may be increased when it approaches the lower limit, while it may be decreased when it approaches the upper limit.

摘要： PURPOSE:To provide an electroplating device, by which the overcoat is effectively prevented from occurring without mechanically masking the edge parts of a steel sheet. CONSTITUTION:In the electroplating device, the non plating electrolyte supply means 5 for supplying non-plating electrolyte such as H2SO4 to the edge parts of the steel sheet 1 are provided in the plating cell 4 having the electrodes 2 of wider width than the sheet width of the steel sheet 1. Thus the overcoat in the edge parts of the steel sheet 1 is prevented from occurring in such an arrangement of each of the edge parts of the steel sheet 1 and the adjacent non-plating electrolyte supply means 5 that they are being apart from each other.

摘要： PURPOSE:To facilitate the manufacture of a rotary current-carrying roll, and to perform the even plating efficiently in the case where a steel plate is carried and electroplated simultaneously. CONSTITUTION:A current-carrying roll 1 is formed into a hollow cylindrical shape by connecting a barrel part 3 and shaft parts 4a, 4b, which are arranged coaxial with the barrel part 3, with bolts, and a conductive sleeve 5 forming the inner peripheral surface thereof is fitted to the barrel part 3 by shrinkage fitting. Loose ends of bus bars 11a-11d, which are supported like a cantilever by a truck 9 provided outside of the current-carrying roll 1, are provided with current-collectors 12a-12b, and connection/disconnection is performed by a link 15a driven by a rod 13a of an air cylinder 13. The current-collectors 12a-12b and the sleeve 5 are electrified selectively. Since the roll 1 consists of the barrel part 3 and shaft parts 4a, 4b, it is easy to form the roll 1 into a hollow cylindrical shape. Furthermore, since the current-carrying is performed through the sleeve 5 provided in the barrel part 3, current is not flowed into the shaft parts, and the uniform plating can be performed efficiently at the time of electroplating a steel plate.

摘要： PURPOSE:To provide a means for effectively preventing overcoating of plating without mechanically concealing the ends of a steel sheet. CONSTITUTION:Nozzles 6 directed to the edges of the steel sheet from the central region at the width of the steel sheet are installed in the electroplating device which is vertically disposed with electrodes 2 broader than the width of the steel sheet to form the plating bath 4 and plates the steel sheet by passing the steel sheet in the intermediate part thereof. A nonplating electrolyte is blown out of these nozzles toward the edges of the steel sheet. Since the nonplating electrolyte is effectively supplied only to the edges, the overcoating of the plating is prevented without causing the deficiency of the plating in the central part of the steel sheet.
