A cylindrical sliding bearing 1 can rotatably support a rotational shaft by a sliding surface 4 (inner circumferential surface). A crowning 5 having a sloped surface is formed at both ends of the sliding surface 4 in the axial direction. The crowning 5 includes a first crowning 3A formed of a sloped surface of a lining layer 3 and a second crowning 2A formed of a sloped surface of a back metal 2 positioned on the lower side of the first crowning. Unlike a conventional sliding bearing, the back metal 2 where the crowning 5 is positioned is provided as a sloped surface (2A). As compared with conventional bearings, the crowning 5 can be prevented from being unevenly brought into contact with the rotational shaft.

Operation keys are selectively invalidated according to the type of an information medium or recorded contents. The medium type of an information medium to be played back is discriminated in addition to detection as to whether or not the information medium to be played back includes information (ADV_OBJ file, etc.) unique to high-definition video information. If the discriminated information medium to be played back is an HD_DVD disc, or if the discriminated information medium to be played back includes an ADV_OBJ file or the like, operation keys (e.g., a repeat key) other than keys used in playback of the HD_DVD disc that records the high-definition video information are invalidated, and operation control is made in response to key operations other than the invalidated key operations.
摘要:
The present invention provides a rotary head comprising a tubular rotary cylinder; and a magnetic head for carrying out at least one of recording and reading of information with respect to a magnetic tape transported about the rotary cylinder; wherein the magnetic head is supported so as to be movable toward the outside of the rotary cylinder.
摘要:
A helically continuous projection 1a is formed around a sliding surface 1A of a sliding bearing 1 at a given pitch p. The surface roughness h of the sliding surface 1A, including the projection 1a, is chosen to be equal to or less than one-half the height H of the projection. This provides a sliding bearing 1 which exhibits an improved running-in performance.
