摘要: A method of producing a silicon carbide sintered body is disclosed. The sintered body having a density of at least 2.4 g/cm.sup.3 is produced by preparing a mixture consisting mainly of silicon carbide with an average particle size of not more than 3.0 microns and a temporary binder, shaping the mixture into a green body and sintering the green body at a temperature of 1,750.degree. C.-2,100.degree. C. Before the sintering, silicon carbide is contacted with either hydrofluoric acid or anhydrous hydrofluoric acid and an atmosphere is held in a non-oxidizing state after the contact treatment up to the completion of the sintering.

摘要: A footstep guide rail (3) (rail body 3a) is arranged so that a level H of a horizontal surface is set at the position obtained by adding a designated offset δ to a tangential line L of a drive sprocket (9) and the footstep guide rail (3) is provided, at its one end on an introductory side of the drive sprocket (9), with a curved part (13). At a reference position closest to the drive sprocket (9), the horizontal surface of the footstep guide rail (3) is changed to the curved part (13). Consequently, it is possible to absorb velocity unevenness of one footstep roller approaching the drive sprocket (9).

摘要: A mountainous or valley-shaped curved part 13 is provided in a part of a footstep guide rail 3 for guiding a movement of footstep rollers 5 linked by a footstep chain 7, the part being positioned in the vicinity of a drive sprocket 9. Consequently, owing to meshing of the footstep rollers 5 with the drive sprocket 9, an unevenness in velocity of the footstep rollers 5 is absorbed by the curved part 13, so that a moving velocity of the footstep rollers 5 moving on the downstream of the curved part 13 is maintained constantly, suppressing vibrating of the footsteps 4.

摘要: Handrail drive belts (20A, 20B, 20C, 120A, 120B) are respectively driven in circulatory fashion within a railing (5) by drive force respectively extracted from step sprocket gears (2a, 2b) and a step chain. The handrail drive belts (20A, 20B, 20C, 120A, 120B) transmit drive force to a handrail belt (10, 110) by contacting the inner peripheral surface of the handrail belt (10, 110) at respectively different locations. In this way, the load on the handrail belt in a passenger conveyor of long travel is reduced.

摘要: A passenger conveyer apparatus including a plurality of steps connected to each other in an endless loop, traveling on a forward path, a backward path and a pair of turning paths connecting between opposite ends of the forward path and the backward path. Each of the steps comprising a step tread and first and second guide rollers offset from each other in the traveling direction of the steps. The apparatus also includes a forward rail configured to guide the first and the second guide rollers in the forward path, a backward rail configured to guide the first and the second guide rollers in the backward path, and a pair of turning rails having a curving rail formed in an arc, configured to guide the second guide roller in the turning paths. At least one of the turning rails is formed in a manner such that a line segment drawn between an orbital center of a corresponding curving rail and a first center of the first guide roller makes an acute angle with a line segment drawn between the orbital center and a second center of the second guide roller, and a loci made by respective turning motions of front and rear edges of the step tread cross each other.
