摘要： A planetarium includes a fixed star field projector and a plurality of planet projectors spaced from the star field projector. A computerized control controls the rotation of the projectors, each of the planet projectors being controlled in its rotation about a pair of perpendicular axes alternatively in two modes, in the first mode the projected image traversing normal apparent orbital or other path in the star field and in the second mode the image traversing the shortest path from an initial point to a terminal point in the star field which points represent different times and/or points of observation.
摘要翻译：天文馆包括固定星形场投影仪和与星形场投影仪间隔开的多个行星投影仪。计算机化控制器控制投影仪的旋转，每个行星投影仪在两个模式中交替地围绕一对垂直轴旋转控制，在第一模式中，投影图像穿过星形场中的正常视轨道或其他路径，以及在第二模式中，穿过从星点的起始点到终点的最短路径的图像表示不同时间和/或观察点。

摘要： A grease composition for EV/HEV driving motor bearing, containing a diurea thickener of the following formula (A): wherein R1, R2 and R3 are defined, with the ratio of the number of moles of the straight-chain or branched alkyl group having 16 to 20 carbon atoms to the total number of moles of the cyclohexyl group and the straight-chain or branched alkyl group having 16 to 20 carbon atoms, expressed as [((the number of alkyl group)/(the number of cyclohexyl group+the number of alkyl group))×100] being 60 to 80%, and a base oil which has a kinematic viscosity at 40° C. of 15 to 50 mm2/s and includes a trimethylolpropane ester oil in an amount of 80 mass % or more based on the total base oil mass. The grease composition can exhibit a long bearing lubrication life at high temperature and high speed, and satisfactory low-temperature flowability.

摘要： A ball bearing includes an inner ring having a raceway surface, an outer ring having a raceway surface, a plurality of rolling elements rollably disposed between the raceway surface of the inner ring and the raceway surfaces of the outer ring, and a resin cage configured to retain the plurality of rolling elements between the inner ring and the outer ring. The cage is a crown type cage having an annular base portion and a plurality of pockets formed in an axial end face of the annular base portion, in which the pockets retain the rolling elements. An axial distance between an axial position of a center of gravity of the cage and a curvature center of a spherical or cylindrical inner surface of each of the pockets is 0.6 or more times a radius of curvature of the inner surface. A hybrid vehicle transmission has this ball bearing.
