Abstract: It is an object of the present invention to provide a grease composition, for an outer ring rotation type rolling bearing, which is capable of satisfying all of high-temperature durability, low-temperature property, peeling resistance, and rust-preventive property. A grease composition (7) to be enclosed in the outer rig rotation type rolling bearing for use in automotive electric auxiliary machines contains base oil, a thickener, a peeling-resistant additive, a wear-resistant additive, and a rust-preventive agent. The base oil is mixed oil of trimellitic acid ester oil and synthetic hydrocarbon oil mixed therewith in a mass ratio of (70:30) to (90:10). The thickener consists of a diurea compound shown by a formula (1). R1—NHCONH—R2—NHCONH—R1??(1) wherein a reference symbol R2 denotes a divalent aromatic hydrocarbon group having a carbon number of 6 to 15, and a reference symbol R1 denotes a cyclohexyl group.

Abstract: In a projection-type video display device that displays an image by projecting the image onto a projection object starting from a desk surface, a display screen on which a position and a gesture operation of a user are reflected is displayed in a predetermined area. An illumination and a camera are disposed in the projection-type video display device installed on the desk surface, a gesture using user's fingers is detected, and, for example, a menu screen and an operation guide are displayed according to the gesture. The shadows of the fingers are photographed by the camera, and a gesture is detected. According to the gesture, the display screen is moved, rotated, divided, or enlarged/reduced, or a menu screen is displayed. The display direction is determined in consideration of the direction of sides of the desk.
