  • Publication number: 20120068930
    Abstract: A grip portion 1 has substantially conical shape having a contour tilted, its bottom face is opened and a fastening portion 3 is formed around the edge of the opening. The sliding portion 2 is coupled to the lower part of the grip portion 1, has a gradual convex surface formed at the bottom-face side, and the convex surface contacts a floor surface and slides thereon. The sliding portion 2 is provided with a receiving portion of a battery or a weight 6, and the top face coupled to the grip portion 1 is in an opened tray-like shape. A sensor hole 7 is formed in the center of the bottom of the sliding portion 2, and another fastening portion 3 is formed around the opening. The grip portion 1 is overlaid on the sliding portion 2 and engaged by respective fastening portions 3.

  • Patent number: 4336352
    Abstract: A polyethylene composition comprising a mixture of three kinds of polyethylenes (A), (B) and (C) characterized in that:(i) the viscosity average molecular weight of (A) is 1,000-100,000, the viscosity average molecular weight of (B) is 100,000-1,000,000, the viscosity average molecular weight of (C) is 400,000-6,000,000, the molecular weight ratio of (B) to (A), i.e. B/A, is 2-200 and the molecular weight ratio of (C) to (B), i.e. C/B, is 1.5 or more.(ii) the mixing ratio of (A) to (B) is 30/70 to 70/30 and the mixing ratio of (C) is 1-10% by weight based on the total composition, and(iii) the melt index of the composition is 0.001-1, and a process for producing said composition. This polyethylene composition is excellent in physical properties in that it has an appropriate die swell, a high melt tension and an excellent moldability and exhibits a high stiffness and a high ESCR.

  • Patent number: 4230831
    Abstract: An intimately melted and homogenized polyethylene composition having excellent physical properties and moldability and comprising a high-medium density polyethylene having a high molecular weight (A), a high-medium density polyethylene having a low molecular weight (B) and a low density polyethylene (C) characterized in that:(i) the average molecular weight of (A) is 100,000-1,000,000, the average molecular weight of (B) is 1,000-100,000, the molecular weight ratio of (A) to (B) is 5-200, and (C) has an intrinsic viscosity [.eta.] of 0.70 dl/g or more in decalin at 135.degree. C. and an expansion factor of 3.3 or more, and(ii) the mixing ratio (A)/(B) is 30/70 to 80/20 and the mixing ratio of (C) in the composition is within the range from 1% by weight to less than 15% by weight.
