Title: Pipe outside surface coating method and apparatus for the same
Inventor: KAJIWARA YOSHIHISA
IPC: B05B13/02
Filed: 2002-03-13
Abstract: <P>PROBLEM TO BE SOLVED: To improve deposition efficiency.  <P>SOLUTION: The outside surface of a rotating pipe P is coated by spraying a coating material (a) from a gun 1. The coating material particles (a) are deposited on the nearer side from the outside surface vertically above the pipe P by inclining the spray direction of the coating material (a) to the nearer side from a spot vertically above the pipe P in the pipe rotary direction and are carried by the air flow caused by the pipe rotation to move to the tip farther side while being deposited by the particle's own weight gravity. As a result, the approach time and the approach distance of the coating material particles with the outside surface of the pipe are prolonged to be easily deposited and to improve the coating efficiency. Further, air (b) is blown from a position farther than the spray position of the coating material (a) to the outside surface of the pipe in the rotating direction. Then air flow caused by the rotation of the pipe is suppressed by the air (b) to block the flow of the coating material particles (a) carried by the air flow. As a result, the approach time of the coating material particles (a) with the outside surface of the pipe is prolonged to be easily deposited and to improve the coating efficiency.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a reinforcing sheet for a construction member imparting a restoring force resisting an external stress in a construction member such as a concrete column or a concrete beam and further, provide a reinforcing sheet capable of securely curing in a short time.  <P>SOLUTION: By using a metallic mesh, a large Young modulus can be given to a construction member, and by using a photo-setting resin, a reinforcing sheet can be forcibly cured in a relatively short time. Hence, workability can be greatly improved. Especially because the surface of a metallic mesh has a metallic luster reflecting light, by diffused reflection of light, light reaches the rear side of the metallic mesh, photopolymerization is initiated by a photoinitiator to cure the sheet.  <P>COPYRIGHT: (C)2003,JPO
