摘要： PURPOSE: To improve the rapidity and safety of operations and quality by installing a freely detachable and conveyable pulling up chamber part on the top surface of a heating chamber part, an automatic fastener and a mechanism for releasing a constraint force of the pulling up chamber part with a conveying mechanism in placing the pulling up chamber part on the heating chamber part and fastening both the chamber parts. CONSTITUTION: This apparatus for pulling up a single crystal is capable of pulling up and housing a silicon ingot 10 grown in a heating chamber part of a main chamber 1 and an upper chamber 6 in a pulling up chamber part of a rotation driving part 8 and a pull chamber 7 with a pulling up wire W, closing a gate valve 5 after housing thereof, operating a conveying mechanism M7, supporting the pull chamber 7 with a supporting arm 18, disconnecting the pull chamber 7 from the upper chamber 6 with an automatic fastener 20, moving the pull chamber 7 to the outer lateral side of a furnace and taking out the ingot 10. Since a mechanism for releasing a constraint force is installed so as to fasten the pull chamber 7 to the upper chamber 6, the connection is carried out simply by the fastening force of the automatic fastener 20. Thereby, the concentricity of the main chamber 1 with the pull chamber 7 is kept to stabilize operations.

摘要： PURPOSE:To facilitate mounting process and improve dynamic performance and workability by mounting a circumferentially successive reinforcing material on a specified section from the top of a steel pipe of one pillar-one pile foundation construction in which a steel pipe provided with internal projections is used as a pile steel pipe. CONSTITUTION:In a one pillar-one pile foundation construction in which a steel pipe provided with internal projections is used as a pile steel pipe 1, a band-type reinforcing material 6 or a ring-type reinforcing material being successive in the circumferential direction of the pile steel pipe 1, is provided in a section Y less than one-half of the embedding length L of a pillar steel frame 4 from the top end of the pile steel pipe 1. Further, a spacer 8 made of styrene foam, etc., is sticked on the whole inside peripheral surface of a section L0 which corresponds to the length L or more. Then, concrete 3 is placed into the pile steel pipe 1, and after hardening the concrete, the concrete 3 in the section L0 is removed and the spacer 8 is also removed. The pillar steel frame 4 is then inserted and fixed, and concrete 3 is loaded between the pile steel pipe 1 and the pillar steel frame to complete the construction.

摘要： PURPOSE:To improve buildup resistance and durability by forming a thermally spray coated layer composed of an alloy having a specified ratio of Cr2O3 and MCrAlY on the surface of a roll and making combined formation of a Cr2O3 covered layer on the above spray coated layer. CONSTITUTION:On the surface of a roll body, is formed an oxide thermal spray coated layer 0.05-3.0mm in thickness, wherein Cr2O3 is contained by 50-80vol.% and the balance is made up of alloy mixture shown by a composition formula of MCrAlY (where M shows Ni, Co and Ni alloy). Then, a coated layer of Cr2O3 is formed doubly on it and pores in the spray coated layer are impregnated and filled with Cr2O3. Since Cr2O3 is poor in wettability and reactivity with iron metal, the buildup resistance for the roll is upgraded. Since the coated layer is strong in wear and abrasion resistance at high temperatures and excellent in adherence to the roll body, the durability of a roll is improved.
