摘要： A combination bearing construction capable of withstanding high-speed rotation and having a high accuracy of rotation is provided. The combination bearing construction comprises a first bearing means, a second bearing means, a third bearing means and a fourth bearing means. The first bearing means bears impulsive forces in a radial direction, which impulsive forces are exerted on a rotary body during rotation, and comprises an inner race (1) and an outer ring (2) which are formed of a silicon nitride based ceramic sintered body. The second bearing means bears a load in an axial direction with a predetermined gap maintained between it and the rotary body, which load is exerted on the rotary body, and is constituted by a magnetic bearing body which comprises two permanent magnets (12, 13) opposing each other in a thrust direction. The third bearing means serves to maintain an accuracy of rotation in a radial direction of the rotary body, and comprises radial dynamic pressure generating grooves (5) formed on a cylindrical surface of the inner race (1). The fourth bearing means serves to maintain an accuracy of rotation in a thrust direction of the rotary body, and comprises an air reservoir (100) confined in a semi-closed condition by the inner race (1), outer ring (2) and a cover (4).

摘要： A ceramic sliding member provided with a sliding face having a surface roughness of 1.0 νm or less in terms of arithmetical mean deviation (Ra). The ceramic includes silicon nitride sinter which contains crystal grains in a linear density of 35 or above per unit length of 30 νm, has a volumetric grain boundary ratio of 15 vol.% or less, and contains pores with a maximum diameter of 20 νm or less in a content of 3 % or less. The production process comprises machining a sliding face and then heating the ceramic in an atmosphere of either an inert gas or air to secure the smoothness of the sliding face. The obtained member has an excellent wear resistance and can be used under severe sliding conditions including high-speed sliding. It can inhibit the occurrence of seizure or abnormal wear on the sliding face even when applied to a sliding part of a compressor using chlorine-free fluorocarbon as the refrigerant.
