  • Cutting insert
    Patent number: 6669412
    Abstract: A cutting insert including a main cutting tooth, a sub cutting tooth and a corner tooth. The main cutting tooth has a honing angle &agr;, and the sub cutting tooth has a honing angle &bgr;. The corner tooth connects the main cutting tooth and the sub cutting tooth, and has honing angles including a maximum honing angle &ggr;1. The honing angles &agr;, &bgr; and &ggr;1 are inclination angles of the main cutting tooth, sub cutting tooth and a corner tooth, respectively. The honing angle &agr; is larger than the honing angle &bgr; and smaller than the maximum honing angle &ggr;1.

  • Cathode-ray tube having electrode with angled outside aperture
    Patent number: 6469432
    Abstract: A cathode-ray tube according to the present invention is able to automatically correct a color shading caused due to a repulsion effect and the like, which occurs between electron beams. An electron gun for use with the cathode-ray tube according to the present invention includes beam apertures bored through a first electrode opposing a cathode disposed in an inline fashion. Further, beam apertures through which so-called side beams pass are bored with a predetermined inclination relative to the opposing cathodes. Consequently, an electron lens formed between the cathode and the first electrode becomes an axial-asymmetric electron lens. The curvature of this electron lens is changed in response to a drive voltage of the cathode. When this curvature is changed, the trajectories of electron beams are changed to cancel an influence caused by a repulsion effect. Thus, a color shading can be corrected automatically.
