摘要： A fiber reinforced plastic pipe is provided to prevent it from being damaged and make full use of its practical performance when the fiber reinforced plastic pipe, reduced in thickness and increased in diameter by pultrusion process, is reduced in the circumferential direction and inserted into a metal pipe. The fiber reinforced plastic pipe, reduced in thickness and increased in diameter by pultrusion process, includes a fiber bundle spun and aligned in the longitudinal direction, and circumferential reinforced fiber sheet provided at least on one of the outer and inner surface layers. The circumferential reinforced fiber sheet is inserted into the metal pipe to form a power transmission shaft such as an intermediate shaft for use with a propeller shaft or a drive shaft.

摘要： To substantially eliminate deficiencies such as portions of the resinous coating, where the film thickness is reduced considerably during the press-fitting, and to aim at providing a high productivity with a reduced cost and without the possibility of occurrence of rusting after a prolonged time of use under severe environmental conditions due to an excellent anticorrosive property, a magnetic encoder (10) includes a multipolar magnet (14) having a plurality of alternating magnetic poles alternating with each other in a direction circumferentially thereof, and a core metal (11) supporting the multipolar magnet (14). The multipolar magnet (14) is formed of a sintered element prepared by mixing and sintering a powdery mixture of a magnetic powder and a non-magnetic metallic powder. The multipolar magnet (14) is fixed on the core metal (11) by staking a portion of the core metal (11), and a sintered element/core metal assembly (21) fixed on the core metal (11) is surface treated to have with an anticorrosive resinous coating (22) for anticorrosive purpose. When the magnetic encoder is press-fitted on an encoder carrier member, one of a press-fitting punch and the magnetic encoder (10) is heated to a temperature within the range of 60 to 150°C. In order to provide an encoder with increased toughness, copper powder Cu should form part of the sintered powder mixture.
