Abstract: An oil-impregnated sintered bearing (8) includes a copper-iron-based sintered compact containing 40 mass % or more of copper, and has inner pores impregnated with an oil. The sintered compact has: a copper structure derived from copper powder (13) of partially diffusion-alloyed powder (11) in which copper powder (13) having a particle diameter of 20 ?m or less is diffused on and joined to a surface of iron powder (12) in advance; and a copper structure derived from elemental copper powder (14).

Abstract: A sintered bearing includes a sintered metal formed by using a metal powder mixture containing copper powder and iron powder. The metal powder mixture contains 80 wt % or more of particles having an average particle diameter of less than 45 ?m. The copper powder contains electrolytic copper powder. The electrolytic copper powder contains 40 number % or more of particles having a circularity of 0.64 or more.

Abstract: A vehicular display device, in which positional adjustment of a display image is easy, is provided, and the vehicular display device (head-up display) 1 comprises a display 3 to emit a display light forming a predetermined display image, a reflecting member to reflect the display light to a driver to have the driver recognizing the display image, moving means (motor) 7 for varying a direction of irradiation of the display light irradiated on the reflecting member to move a display position of the display image, operation means (control unit) 14 to allow driving of the moving means 7, and control means 11 for displaying a mark indicative of a display range of the display image when the operation means 14 is operated.

Abstract: A reflecting mirror is rotatably supported and reflects display light. A stepping motor rotates the reflecting mirror. Storage means can store position data in accordance with the rotation position of the reflecting mirror for each user. Control means receives an identification code from a keyless entry device for specifying the user, reads out position data corresponding to the identification code from the storage means, and operates the stepping motor according to the position data which has been read out.
