    摘要： To provide a rolling bearing in which a spin slippage between a rolling element and a raceway groove is suppressed, and a rolling resistance is reduced to make the torque lower, whereby the rolling elements are easily incorporated even when the bearing rings are the monolithic type. Also, to provide the rolling bearing in which the rolling elements are easily incorporated even in a state where the bearing rings of monolithic type and a retainer are assembled. After the outer and inner races and the retainer are assembled, a small groove 4 for rotating the rolling element is provided in the center of an inner raceway groove 3 within a raceway groove space. The retainer 6 is only provided in one axial pocket face 7b of a pocket 7, and the other face is opened.

    摘要： The radii of curvature RD, RS and RL along a diagonal axis, a short side and a long side of an outer surface of a useful portion of a panel whose inner surface is provided with a phosphor screen satisfy RD≧10 m, RS>RD, and RL>RD. This makes it possible to provide a color picture tube that has an excellent visibility and is not susceptible to the deterioration in color purity due to doming, while including a shadow mask with excellent formability and strength.

    摘要： A method of producing rolling elements for a rolling bearing comprises mixing to process rounded elements made of steel balls and spherical rolling elements having outer diameter portion portion becoming a rolling contact face. The rolling contact face has curvatures in an axial direction and a radial direction normal to the axial direction, and has at least one plane. The thus mixed elements are placed and processed in a space between two processing boards opposing each other via the determined space. Thereby, the surfaces of the rounded balls and the rolling elements are processed to be rounded.

    摘要： A color cathode ray tube has a substantially rectangular shadow mask in which a plurality of slit type aperture arrays are aligned in the direction of the major axis of an effective region defined by a curved surface opposing a phosphor screen formed on the inner surface, defined by a concave curved surface, of the effective region of a panel. Each slit type aperture array is obtained by arranging a plurality of slit type apertures in an array in the direction of the minor axis of the effective region of the shadow mask. In this color cathode ray tube, the difference between the array interval of the slit type aperture arrays at a peripheral portion on the long side of the shadow mask and the array interval of the slit type aperture arrays on the major axis is a maximum value within a distance range of 0.4 h to 0.9 h (h is 1/2 the length of the effective region of the shadow mask in the direction of the major axis) from the minor axis, and the array interval of the slit type aperture arrays at the end of the major axis is larger than that of the slit type aperture arrays at a corner. Thus, local doming of the shadow mask can be suppressed.
