A communication apparatus for carrying out communications to and from an external apparatus that includes a first interconnecting unit and a first non-transparent port and effects an interconnection for communications via the first non-transparent port is provided. The communication apparatus includes a second interconnecting unit that includes a second non-transparent port communicably connected to the first non-transparent port. The second interconnecting unit effects an interconnection for communications via the second non-transparent port. The second interconnecting unit performs, when the communication apparatus carries out communications to and from the external apparatus, address translation between an address for use by the communication apparatus and an address for use by the second non-transparent port.

This method is characterized in that a ring-shaped jig is disposed on a workpiece on a machine tool, and the optical axis of a camera is aligned parallel to a single axis of the coordinate system of the machine tool. The jig is photographed using the camera in which the horizontal direction or the vertical direction of the camera is aligned with an axial direction other than the signal direction of the machine tool, and the circumferential shape of the jig in the image photographed by the camera is extracted as a contour. The center position of the jig in the image is calculated from the contour while all the distortion correction coefficients in tangential direction and all the distortion correction coefficients in the radial direction are ignored and set to zero. The displacements of the main point of the camera are all set to zero so as to be included in the translation distance of the camera. The translation distance, which is an external parameter of calibration, is calculated on the basis of the center position of the jig in the image and the known three-dimensional center position of the jig.

A stainless steel slab containing B, wherein a protecting material is joined onto at least two faces across the bloom from each other in a stainless steel bloom containing B of 0.3–2.5 mass %, being integrated into one-piece by forming a weld metal comprising a stainless steel with chemical composition that satisfies the relationship expressed by following formulas (1)–(4), and a method to produce a steel product by rolling said slab. Further, it is preferable to interpose an insert material between above stainless steel bloom and above protecting material in bonding process. 15≦Cr eq≦30, (1) 4≦Cr eq−Ni eq≦17, (2) Cr eq=Cr+1.5 Si+Mo−5 B, (3) Ni eq=Ni+30 (C+N)+0.5 Mn (4) Herein, each symbol of a chemical element designates the content (mass %) of relevant chemical element contained in steel. Accordingly, it makes it possible to subject a stainless steel slab containing B to hot working without generating edge cracking, so as to be used as a source material of a neutron shielding container and a separator of a fuel cell.
