A value=(100×[C]−6×[insol.Cr]−2×[insol.Mo]−24×[insol.V]−13×[insol.Nb])×([Mo]−[insol.Mo]), where [insol.Cr], [insol.Mo], [insol.Nb], and [insol.V] are contents (in mass percent) of Cr, Mo, Nb, and V, respectively, present as a compound after stress-relief heat treatment, and [C] and [Mo] are contents (in mass percent) of C and Mo, respectively, contained in the weld metal. | 11-28-2013 |
20130153368 | FEEDING SYSTEM FOR REDUCED IRON MATERIAL - Not only the cracking of granular reduced iron materials is reduced, but also reduced iron materials are fed uniformly onto a furnace floor regardless of a width of the furnace floor. A feeding system for reduced iron material includes a plurality of material feeding equipments | 06-20-2013 |
20110278272 | ROBOT CONTROLLER THAT CONTROLS TANDEM ARC WELDING SYSTEM, ARC TRACKING CONTROLLING METHOD USING THE ROBOT CONTROLLER, AND THE TANDEM ARC WELDING SYSTEM - A robot controller that controls a tandem arc welding system according to the present invention includes a leading-electrode correcting section that calculates a leading-electrode correction amount, used for correcting a displacement in a left-right direction and an up-down direction, from a leading-electrode changing amount calculated by a leading-electrode processing section; a leading-electrode correcting section that calculates a trailed-electrode correction amount, used for correcting a displacement in a rotational direction, from a trailed-electrode changing amount calculated by a trailed-electrode processing section; a rotational-displacement correction controlling processing section that calculates a rotational-center correction amount for correcting the displacement of the leading electrode; and a robot trajectory planning processing section that corrects a teaching position and a position of a rotational center of a welding torch during tracking correction. By such a structure, even if arc tracking is carried out at any rotational center, displacement of the leading electrode does not occur, so that defective welding does not occur. | 11-17-2011 |
20100179230 | METHOD AND APPARATUS FOR MANUFACTURING LIQUID MICROSPHERES - The present invention provides microsphere manufacturing method and apparatus capable of stable obtaining microspheres of a desired size and reducing facility cost. According to the method and the apparatus, to manufacture microspheres made of a second liquid in a first liquid, the first liquid is supplied into a first channel to flow therein and the second liquid is supplied to an intermediate part of the first channel through a second channel. The supply velocities of the first and second liquids are set such that the second liquid closes the first channel and the closing part of the second liquid is cut off due to a pressure difference between an upstream side and a downstream side to form microspheres. | 07-15-2010 |
20100135844 | COLD-WORK DIE STEEL AND DIE - The present invention relates to a cold-work die steel, comprising by mass %: 0.5 to 0.7% of C; 0.5 to 2.0% of Si; 0.1 to 2.0% of Mn; 5 to 7% of Cr; 0.01 to 1.0% of Al; 0.003 to 0.025% of N; 0.25 to 1% of Cu; 0.25 to 1% of Ni; 0.5 to 3% of Mo; 2% or less (including 0%) of W; and 0.1% or less (excluding 0%) of S, with a remainder being iron and an unavoidable impurity; wherein the following requirements (1) to (3) are satisfied: (1) [Cr]×[C]≦4; (2) [Al]/[N]: 1 to 30; and (3) [Mo]+0.5×[W]: 0.5 to 3.00%, wherein the bracket means a content (%) of an element written therein. | 06-03-2010 |
20100019540 | VEHICLE BODY PANEL STRUCTURE - A vehicle body panel structure, wherein an inner panel is disposed on the inner surface of an outer panel and a reinforcing inner panel is disposed on the inner surface of the inner panel. A plurality of recesses and projections forming a wave shape in cross section are formed on the inner panel and the reinforcing inner panel in the longitudinal direction of a vehicle body. These panels are joined to each other so that a closed cross section is formed of the inner panel and the reinforcing inner panel at the lower part of a joined part between the outer panel and the inner panel and a closed cross section is formed of the outer panel and the inner panel at the upper part of a joined part between the inner panel and the reinforcing inner panel. Accordingly, even if a head part moving distance is small, an HIC value can be lowered and uniformized at those portions other than an impact portion. Thus, even an Al alloy hood can sufficiently reduce the HIC value to contribute to a reduction in the weight of the vehicle body. | 01-28-2010 |
