Abstract: A method and a system for diagnosing an apparatus are provided. The method for diagnosing the apparatus includes: determining whether the apparatus is to enter a diagnostic mode after a system is started; performing a diagnosis of the apparatus by executing a diagnostic proge apparatus is determined to enter the diagnostic mode; and performing a normal BIOS or EFI startup when the apparatus is determined not to enter the diagnostic mode. An accurate diagnosis of the apparatus can be realized by firstly determining whether the apparatus is to enter a diagnostic mode after a system is started, if yes, then the apparatus entering the diagnostic mode, and if not, then the apparatus performing a normal BIOS or EFI startup. Moreover, in case of a memory or PCI/PCIE bus error in the apparatus, since the diagnostic program is loaded prior to the BIOS startup, the fault can be diagnosed.

Abstract: Disclosed in the present invention are a method and a system for managing basic input/output (BIOS) configuration data of a BIOS. The method includes: reading a BIOS program code, and executing a BIOS program; when executing the BIOS program, executing different code segments in the BIOS program according to read BIOS configuration data; and when new BIOS configuration data is required for executing the BIOS program, using a value in a new storage area as the new BIOS configuration data. Through the solution provided by the present invention, it can be ensured that, after the BIOS program is upgraded and when the number of configuration items is increased, current BIOS configuration data in a storage medium is still read effectively.

Abstract: An object of the present invention is to provide a forming method and a forming machine in which in forming e.g., a round steel pipe, predetermined forming can be performed with less additional deformation imparted to a workpiece without deteriorating the productivity of the conventional roll forming, thereby manufacturing a high-quality product with high dimension precision. To achieve this object, the present invention provides a forming method and a forming machine, which adopt a rotating unit which rotatably moves on an endless track a die train having dies with outwardly directed and swingable forming passes in a breakdown step at an early forming stage, and in which the forming pass of each die holds the edge of the workpiece to rotatably move the die by changing the die to a predetermined angle, thereby realizing bending, so that problems due to twisting onto forming rolls and high locally-caused contact stress can be greatly reduced.

Abstract: An object of the invention is to provide a device and a method for controlling a welding angle which is capable of resolving restrictions occurred when a conventional float type welding angle control device is used to manufacture a welded pipe, and giving full play to the ability of such a float type welding angle control device, by adopting a new mechanism for supporting and adjusting a fin roll. When the welding angle is controlled by inserting the fin roll between opposing edges of a band steel at a position located in an upstream side of squeeze rolls, the fin roll is attached to a link mechanism in which two arms are coupled so as to be pivotable within a plane defined by a pipe manufacturing line direction and a perpendicular direction thereof, and positions of gripping points of the arms are changed to adjust a position of the fin roll within the plane.

Abstract: A rotary face plate per se is simply configured by including only a machine mechanism for rotating it on its axis. In order to achieve the configuration, a swing arm for a rotary blade is mounted on one side of the rotary face plate whereas a driving motor and a swing motor for the rotary blade in each of the swing arms are independently mounted on each of the swing arms on the other side. One side has only a function of rotating and cutting on the boundary of the face plate, and therefore, cutting chips can be remarkably readily removed. Only a rotating motor for a drive source is mounted on the other side. As a consequence, a round tube or a square tube having a square cross section can be completed to be cut only by controlling the motor for rotating the rotary face plate per se at a required angle.

Abstract: Roll forming a round tube to a square tube without applying excessive load to the raw tube scheduled portions to become corner portions and shoulder portions. This invention structures the curvature of the rotation axis direction of the forming roll surface in a way that in relation to other raw tube locations (straightening precedes for the raw tube locations adjacent to the corner portion scheduled locations of the square tube. It disposes stands of four-direction roll structure at the forming roll stand furthest upstream and furthest downstream sides and disposes stands of upper-lower and left-right two-direction roll structure between the upstream and downstream roll stands, and by adopting forming roll with a structure having a curvature for constricting the raw tube locations to become the shoulder portions adjacent to the corner portions of the square tube at a smaller curvature than that constricting the raw tube portions to become the side portion centers of the square tube cross section.

Abstract: Disclosed are a forming apparatus and method that are able to form a required sectional profile by a variety of forming methods, such as roll forming, die forming or shoe forming, etc., when forming round tubing, angled tubing or open forming stock, are able to perform the required forming in any of these forming processes without losing the manufacturability of conventional roll forming and imparting minimal additional deformation to the formed stock, and that can manufacture high-quality goods with high dimensional precision.

Abstract: A straightening method is presented where a concave roller, which has a roller caliber and in which the projection of the roll caliber forms an arc with respect to the cross section of a pipe. The projection arc radius can freely be changed by adjusting the angle between the roller axis and the axis line of the pipe. A plurality of concave rollers are arranged on the outer surface of the metal pipe in the circumferential direction, and rolling is applied on the outer diameter of the pipe while revolving these rollers about the pipe axis.

Abstract: It is an object of the present invention to provide a novel roll-forming method for steel pipes and equipment for same with which (1) the evidence that forming work in the FF forming method is mainly carried out at the cluster forming portion showing the poor formability is modified and improved without any deteriorating the advantage of the common-utilization of rolls in the FF forming method which employs basically the circular-bend method, and (2) the forming function at the breakdown forming portion is enhanced. Accordingly, the pinch-point formed by the upper and lower rolls is set at a boundary area between the target forming zone in the material's width direction and previously-formed zone or un-formed zone.
