    摘要: An antireflection film is procided on a plastic optical element as follows. An undercoat composed principally of unsaturated silicon exide SiO.sub.x (2>x>1) with a thickness within a range of 200 to 300 nm is formed on the optical element. A multi-layered film of a repeating structure is formed on the undercoat. The multi-layerd film has antireflective characteristics. The undercoat has a refractive index within a range of 1.49 to 1.59. The multi-layered film is composed of alternate lamination of a layer of a material which has a high refractive index and which is composed principally of TiO.sub.2, ZrO.sub.2 or a mixture thereof, and a layer of a material which has a low refractive index and which is composed principally of SiO.sub.x (2.gtoreq.x.gtoreq.1).

    摘要: A saddle-ride type vehicle in which the body frame can be reinforced without using a special reinforcing member includes left and right rear frame portions extending rearward and upward from a down frame. The right and left rear frame portions each include a rear frame front half portion and a rear frame rear half portion that are joined together at a joint. The left and right rear frame front half portions are connected to each other by a cross frame. The rear frame rear half portions extend further forward from its joint with the rear frame front half portion and are also joined together by the cross frame, which supports a seat through a storage box.

    摘要: In order to not only obtain excellent sound quality in a long-time recording mode not less than five times a standard recording mode by preventing, without narrowing a track pitch of a high-fidelity head, the high-fidelity head from tracing the third sound track from a target sound track as well as excellent picture quality free from crosstalk from an adjoining video track of a target video track but enable special playback without using a field memory in a video tape recorder, one head pair in conventional double azimuth type four heads for the standard recording mode and a threefold recording mode is used for video recording in the long-time recording mode and a head pair having a head width smaller than a width of a recording track is used exclusively for video playback in the long-time recording mode.
