摘要： A widthwise-compressing machine for applying a compression force through press tools to a material to reduce a width of the material while applying vibrations to said material to forcibly vibrate said material has a compression unit for producing a compression force forming a working force, and a vibration-applying unit for applying the vibration to said material. The vibration-applying unit is provided independently of the compression unit. In the widthwise-compressing machine, when the material is plastically worked, the material can be vibrated at an extremely high frequency to make it possible to resonate the material, thereby allowing the plastic-deformation thereof to be promoted.

摘要： An upper shearing blade equipped with a protrusion of a triangle-columnar shape and a lower shearing blade equipped with a protrusion of the same shape are applied onto the overlapped portion of metal plates to be bonded, and then pressed into the metal plates in an oblique direction inclined with respect to the thickness direction by a stroke in such a range that the metal plates are not completely cut off. The operating loci of the upper, shearing blade and the lower shearing blade are overlapped each other so that one falls inside the other, and the sheared surfaces of the metal plates are formed into a bonded portion by plastic flow deformation. Therein, since a compressive force is applied onto the portions to be bonded, the portion being defined by the amount of overlap, and the portions are compressed to form a compressed portion after completion of bonding, the bonding strength enhances. Besides, since the protrusions on the shearing blades generate a pressing force pressing the sheared surfaces onto each other, by an effect of their inclined surfaces, a compression force applied onto the bonded portion further increases.
摘要翻译：将配备有三角柱状突起的上剪切刀片和配备有相同形状的突起的下剪切刀片施加到要接合的金属板的重叠部分上，然后以倾斜的方式压入金属板相对于厚度方向倾斜的方向为金属板未完全切断的范围内的行程。上剪切刀片和下剪切刀片的操作轨迹彼此重叠，使得其彼此落下，并且金属板的剪切表面通过塑性流动变形形成接合部分。其中，由于在要接合的部分上施加压缩力，该部分由重叠量限定，并且在结合完成之后压缩该部分以形成压缩部分，因此提高了接合强度。此外，由于剪切刀片上的突起产生按压剪切面彼此的挤压力，所以通过它们的倾斜表面的作用，施加在接合部分上的压缩力进一步增加。

摘要： In a tandem mill system, at least one first type rolling mill is arranged in the upstream side and at least one second type rolling mill is arranged in the downstream side. The first type rolling mill is of the so-called work roll crossing mill in which a pair of work rolls are inclined with respect to a pair of back-up rolls supporting the work rolls and simultaneously crossed each other in a horizontal plane to control transverse thickness distribution of a strip. The second type rolling mill is of the so-called HC mill which controls the strip crown and shape by a combination of axial movement of intermediate rolls and work roll bending. Such an arrangement makes it possible to increase a capability of controlling the strip crown and shape, particularly, a capability of correcting the quarter buckle, and eliminate a fear of causing scratches on the strip and roll surfaces, with the result of improved production efficiency. Plural lines of lubricant supply device are also provided to stop supply of a lubricant immediately before biting of the strip into the work roll crossing mill and start the supply again after the biting. A system of lubricating the work roll crossing mill is thereby improved.

摘要： To eliminate a vertically asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of upper and lower work rolls 2, 3 during rolling, a device for comparing values measured on the upper and lower sides and calculating the difference therebetween, and a horizontal deflection controller four determining whether the difference exceeds a predetermined range or not and imparting a horizontal bending to at least one of the work rolls. To eliminate a transversely asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of at least one of the work rolls at axially spaced positions during rolling, a device for comparing values measured on at the axially spaced positions and calculating the difference therebetween, and a horizontal deflection controller for determining whether the difference exceeds a predetermined range or not and imparting a horizontal bending to the one work roll at least one of the axially spaced positions. This prevents an adverse effect by the work rolls being horizontally deflected in a vertically or transversely asymmetrical way, reduces the diameter of the work rolls, and increases the allowable rolling load. Stable rolling of high-quality strips with good shape or flatness is thus achieved.

摘要： A sealing structure in which free-cutting spacers on a sealing base plate and sealing fins on a rotor are opposed to each other is provided. The sealing base plate is disposed so as to be movable in an axial direction of the rotor. When a steam turbine increases in load, a pressure head moves in an axial steam-pressure loading direction of the rotor and the sealing base plate connected to the pressure head moves in the axial steam-pressure loading direction. Since the free-cutting spacers at positions opposed to those of the sealing fins existing after the movement of the sealing base plate are maintained in a non-contact state, clearances between the sealing fins and the free-cutting spacers are dimensionally minimized.
