Title: Welding method for al-li alloy material
Inventor: KOBAYASHI KAZUNORI
IPC: B23K9/23
Filed: 1993-01-20
Abstract: PURPOSE:To attain a defectless and strong welding structure body by performing the arc welding of an Al-Li alloy within a specific range of a welding current value and a welding speed respectively. CONSTITUTION:An arc welding is performed to an Al-Li alloy within ranges that a welding current value is 90 to 150A and a welding speed is 14 to 23cm/ min. Since the melting temperature of an Al-Li alloy is lower than that of the structural Al alloy, a welding is possible by a low current. With that, even if a welding speed is made fast, proper welding beads can be formed. In a state of <90A welding current, the penetration of a joined portion is insufficient, and proper welding beads are not formed. When the welding current exceeds 150A, the penetration is violent, a part influenced by heat is enlarged, and the performance of a joint strength, etc., deteriorate. In a state of <14cm/min welding speed, the penetration is violent. When it exceeds 23cm/min, the penetration is insufficient, and proper welding beads are not formed.

Filed: 1988-01-19
Abstract: PURPOSE:To enable even an operator who has no technical knowledge of characteristics to easily calculate insurance points by selecting a formula among those plural prepared types of general formulas in response to check contents. CONSTITUTION:A check item receiving part 1 sends a set item if detected to a set item calculation part 2 out of inputted information. The part 2 performs the set calculation based on said set item and stores the result of this calculation in a memory part 2a. In the same way, the part 1 sends a combined calculation item if detected to a combined item calculation part 3 and other remaining simple items to a simple item calculation part 4 respectively. Thus the part 3 carries out the combined calculation and stores the result of this calculation in a memory part 3a. Then the part 4 carries out single calculation and stores the result of this calculation in a memory part 4a. When the parts 2-4 work, a formula is selected out of plural prepared types of general formulas in response to the check contents. Thus the insurance points are calculated and totalized 5 for output 6.

Filed: 1986-01-17
Abstract: PURPOSE:To impart a constant configurational dimension and strength, by controlling the amount of a powder pushed in between pistons by automatically adjusting the rotation of a powder mixing and push-in blade so that the configurational dimension of a detected pellet coincides with an objective value. CONSTITUTION:At the time of the finish of compression molding, the relation between two pistons 49, 50 detected by position detectors 55, 56, that is, the thickness of a formed pellet is inputted to an operational controller 53. On the basis of this information, the number of rotations of an electromotor 44 are changed by the operational controller 53 to adjust the feed amount of a powder to a powder receiving part 46 by a powder mixing and push-in blade 45. Concretely, when the thickness of the formed pellet detected as the gap between the pistons 49, 50 by the position detectors 55, 56 at the time of the finish of compression is larger than an objective value, the number of rotations of the electromotor 44 are lowered to reduce the amount of the powder fed to the powder receiving part 46 by the powder mixing and push-in blade 45.

Abstract: PURPOSE:To atomize the liq. droplet to be sprayed by providing a throttle part having a cross section smaller than a confluent part side to the ejection port side of a nozzle in the confluent passage of a two-fluid spray nozzle. CONSTITUTION:The spray nozzle especially the two-fluid spray nozzle is used for atomizing low-range fuel oil and reducing the dust in waste gas, when a fluid to be atomized and an atomization fluid are fed forcibly under pressure. A confluent passage 9A is provided and connected to the conical part of an atomization fluid passage 7, and a confluent passage 9B leading from the conflu ent passage 9A to the ejection port on the front surface of the nozzle forms a throttle part having a cross section smaller than that of the confluent part 9A. Consequently, an atomization fluid B joins the fluid A to be atomized at almost right angles to each other, and is throttled by the passage 9B. Besides, the fluid A is detached from the wall surface of the passage, and atomized uniformly by the fluid B. Accordingly, the droplet to be sprayed is atomized, and the combustion efficiency can be enhanced even when low-grade fuel oil is used.

CONSTITUTION:An edge point surface 8a, if an edge tool 8 is inserted to be longitudinally slided between an abrasive surface 25 of a base bed 10A and an abrasive surface 28 of a base bed 10B, is brought into contact with cemented carbides 16 on the base bed 10A and cemented carbides 16b on the base bed 10B, and rough polishing is performed. While a part 8b other than the edge point surface can be brought into contact with the cemented carbides 16 and cemented carbides 16a applying rough grinding by sliding the edge tool 8 tilting its upper end side to angles as shown by arrow heads alpha, beta. And if abrasive work advances, the edge tool 8, when it is slided, is brought into contact with and cooled by a water absorptive material 20 by infiltrating water in a water storage part into the water absorptive material 20, and water adhering to the edge tool 8 disperses on front faces of the abrasive surfaces 25, 28 forming a water film, thus cooling the cemented carbides 16, 16a, 16b.

Abstract: PURPOSE:To effect more severe objective value control and high-grade power control by a method wherein the storing, renewing and printing of a maximum demand value, a contracted power value and an obtactive value are operated in an operational processing unit. CONSTITUTION:An operational processing unit 32 operates an actual maximum demand value of each month and stores the maximum demand value in past one year into a memory unit 34 while renewing it every months. The operational processing unit 32 renews a contracted power value and an objective value every months and records by printing the contracted power value, the increasing and decreasing value of the same and an estimated value of next month through a printer unit 35. The transitions and increasing and decreasing values are printed and, therefore, the status can be seen at a glance for the control of power. On the other hand, a schedule thereafter and a control program can be established whereby more severe objective value control and high-grade power control can be effected. Further, a problem where the power control is effected with same objective value throughout one year or the power control is set manually or setting thereof is missed, can be eliminated.

Abstract: PURPOSE:To provide an atomic power plant and a water quality control method, a fuel rod, and a fuel assembly for the atomic power plant and capable of sufficiently suppressing the redissolution of the activated nuclid into a reactor water. CONSTITUTION:A water contact surface on the inside of a channel box 12 is formed of a high potential material layer 13 (for example, magnetite is formed in a film on the water contact surface on the inside of the channel box 12 by plating) higher in potential than a mixed clad 15 adhered to the surface of a fuel clad pipe 11a. A current is carried from the high potential material layer 13 having a high potential to the mixed clad 50 through the surface of a fuel clad pipe 11a, and since the mixed clad 50 is lower in potential than the high potential material layer 13 to form in an oxidizing environment for emitting electrons, the redissolution of ferrite contained in the mixed clad can be suppressed.
