    • The invention is directed to an RTK-GPS survey system. The survey system includes a server (9) in an IP-VPN communication network 10 for establishing communications between base stations (16 and 17) that transmit correction data and a rover station 15 that receives the correction data. Each satellite positioning device constituting a base station and a rover station includes at least a satellite positioning unit (11) that receives radio waves from artificial satellites, a communication unit (12) that performs a communication between the satellite positioning device, and a control unit (13) that controls the satellite positioning unit (11) and the communication unit (12). The control unit (13) of the rover station 15 can receive interference information registered in the control unit (13) of each satellite positioning device of the base stations (16 and 17), and select a base station that transmits most appropriate correction data among the plural base stations.

    • 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.
