摘要： A hollow cylindrical pulley body 5 is carried rotatably by a hollow cylindrical shaft member 11. A support rod 8 is inserted in the shaft member 11, and the shaft member 11 is elastically supported to the support rod 8 through an elastic body 10. The elastic body 10 is provided within a quarter of the periphery of the support rod 8 that is located, when viewed along the axis of the shaft member 11, forward of the line of action of a radial shaft load on the shaft member 11 with respect to the direction of rotation of the pulley body 5. With this configuration, when the drive belt 3 deviates to one side, the pulley body 5 is immediately angularly moved so that it is inclined with a level difference with respect to the direction of the radial shaft load and is positioned obliquely relative to the drive belt 3. In this manner, a force of compensating for the deviation of the drive belt 3 is produced to avoid its wobbling.

摘要： A dry vacuum pump assembly that includes a casting having an inner chamber, an inlet and an outlet communicating with the inner chamber, a pair of right and left handed screw rotors positioned in the casing, each screw rotor having a cross section formed by a Quimby curve, a circular arc, and a quasi-Archimedean spiral curve, the pair of screw rotors intermeshing with each other to pump a process gas pumped from the inlet to the outlet. The pump assembly further includes a nitrogen-supplying tube that communicates with the inner chamber at a position near the outlet in the casing, and an external pipe that connects the outlet to a scrubber or a trap which external pipe is straight and does not include a silencer.

摘要： A silicon sintered body comprising a matrix phase consisting of silicon nitride and a grain boundary phase in which the silicon nitride consists of 66 to 99% by volume of .beta.-Si.sub.3 N.sub.4 and/or .beta.'-sialon with the balance being .alpha.-Si.sub.3 N.sub.4 and/or .alpha.'-sialon, the .beta.-Si.sub.3 N.sub.4 and/or .beta.'-sialon consisting of hexagonal rod-like grains having a diameter of 500 nm or less in the minor axis and an aspect ratio 5 to 25, the .alpha.-Si.sub.3 N.sub.4 and/or .alpha.'-sialon consisting of equi-axed grains having an average diameter of 300 nm or less, and titanium compounds are contained within the grains of the matrix phase and in the grain boundary phase. The sintered body is produced by mixing (1) 100 parts by weight of .alpha.-Si.sub.3 N.sub.4 powder, (2) 0.1 to 10 parts by weight of titanium oxide having an average particle size of 100 nm or less and (3) 2 to 15 parts by weight, in total, of specified sintering aids; molding the resultant powder mixture into a green compact; subjecting the green compact to primary sintering and secondary sintering under the prescribed conditions.
