摘要： PURPOSE:To prevent a peak of a thickness increase rate, and to prevent a defect such as an irregular deformation, an intercrystalline crack, etc. by raising nonlinearly a pressure speed of a pipe material until it reaches a prescribed speed and controlling it to a slow rise pressure speed, when starting a thickness increase working of the pipe material. CONSTITUTION:A pattern of a pressure speed of a pressure cylinder 3 is set so as to go to nonlinear at the time of rise by a speed control device 12, and also thereafter, so as to reach a prescribed speed. Subsequently, based on the speed pattern, the pressure cylinder 3 is brought to a driving control by controlling an opening of a servo-valve 10 of the pressure cylinder 3. In such a state, when the pressure cylinder 3 starts to move gradually, a position detecting means 9 detects momentarily a moving position of the pressure cylinder 3, and the speed control device 12 executes an operation and controls continuously the next opening of the servo-valve 10, based on a prescribed speed pattern, therefore, a speed at the time of rise of the pressure cylinder 3 and a prescribed speed after the rise are controlled with a high accuracy, and it is suppressed that the thickness increase rate reaches a peak.

摘要： PURPOSE:To relieve a stress concentration caused by a large electromagnetic force produced in a water cooled coil of a hibrid magnet system by a method wherein a plurality of helical coil layers are arranged coaxially and concentrically and the plate thickness of each layer to the side of a cylinder supporting both ends is varied. CONSTITUTION:The plate thickness to the side of cylinder supporting both ends at a jointing part 6 is varied to distribute the stress concentrated to the neighborhood of an end 61 of the jointing part over the whole jointing part 6 and the maximum stress near the end of the jointing part 61 is reduced and the stress is prevented from exceeding the allowable valve. A shaded part 7 in the figure shows the jointing part of a oil conductor 11 and the cylinder 12 supporting both ends.

摘要： PROBLEM TO BE SOLVED: To eliminate an unstable molten state of a base material and to obtain the sound result of welding by detecting an arc voltage only in an optional electrode position, calculating the difference voltage between the arc voltage and the reference arc voltage and vertically transferring a welding torch with respect to the base material. SOLUTION: An arc voltage detection is commanded to an arc voltage detecting device 17 by a unified controller 20 when the welding torch 3 'is detected to be in the prescribed position of a weaving amplitude. The arc voltage is detected by the arc voltage detecting device 17, the difference voltage between the arc voltage and the reference arc voltage is calculated by a difference voltage calculating device 18, and the transferring amount of a welding torch supporting part required for becoming a suitable arc length is calculated from the difference voltage with a transfer calculating device 19 of a welding torch supporting part. The arc length is judged to be large with the unified controller 20 when the difference voltage is positive, the command to drive in the direction approaching to the base material 4 is sent to a welding torch supporting part transfer stage controller 12, while the arc length is judged to be small when the difference voltage is negative, the command driving in the direction separating from the base material 4 is sent to the same, whereby a welding torch supporting part transfer stage 11 is driven via the command.

摘要： PURPOSE:To make information control efficient by adding various attribute data on a negotiation object person who samples memorandom records and a time series in sampling units of memorandom information. CONSTITUTION:When a consumer 110 demands the repair of equipment, etc., a supervisor 108 in charge of consumer service investigates the contents of an object base 104 stored with relative information, retrieves the contents of the memorandom information in a memorandom data base 101 in time-series order when the memorandom information is present, and passes the result as memorandom history information 11 to an engineer 109 on a business trip. The engineer on the business trip visits the consumer by referring to the memorandom history information 11 and performs the operation. The operation result and negotiation contents are recorded as memorandom information 112 and the memorandom contents are read through a scanner 107 after the engineer returns to the company. The supervisor 108 extracts only necessary parts from the inputted memorandom information and adds them to the consumer memorandom information in the memorandom data base 101. Consequently, the information control is made efficient.

摘要： PURPOSE:To measure the pitch size between the commutator bar and the insulating material of a commutator highly accurately and continuously by combining and using an optical displacement gage and a rotary angle scale for the commutator. CONSTITUTION:In a commutator 1, commutator bars 1a and insulating materials 1b are alternately arranged in a ring shape. The commutator 1 is mounted on a rotary table 4. The rotary table 4 is rotated by a driving device 5. The rotary angle is read with an angle scale 3. An optical displacement gage 2 is provided at the outer surface of the commutator with a specified distance being provided. The distance to the commutator 1 is measured. The rotary table 4 is rotated, and the output of the angle scale 3 at a position where the output of the optical displacement gage 2 is suddenly changed is read. Thus the pitch of the commutator 1 is accurately measured.

摘要： PURPOSE:To bend a plate material by one stage and to reduce the man-hour for the work by changing a bending span due to the movement of a bolster prepared in an equipment and a pressurizing position of an upper die in bending a plate material in a semi-ring shape. CONSTITUTION:A material 1 is positioned at a prescribed site on the bolster 2. Then, the bolster 2 is moved by the drive of a hydraulic cylinder, etc., simultaneously with bending work to reduce a bending span. At this time, pressure is applied from a press 7 through an upper die 3 and bending work is carried out gradually. In addition, in time of the final bending, that bending span is enlarged to be worked by application of the final pressure of the upper die 3 in a prescribed semi-ring shape. Furthermore, if the bolster 2 is moved up or down this structure can correspond even to H-dimension determined by various bending shapes.
