  • Publication number: 20030178856
    Abstract: A wind power generator provided with a wind turbine rotating in a wind tunnel body, capable of generating high output power by efficiently accelerating a wind flow. The wind power generator comprises a cylindrical wind tunnel body (1) expanding toward a flowing direction of wind and a wind turbine (3) for generating electricity disposed at a position adjacent to an inlet (2a) for wind of the wind tunnel body (1), wherein an angle of inclination &phgr; of a side wall portion of the wind tunnel body (1) against an axis of the wind tunnel body (1) is in a range from 5 to 25 degrees, the inlet (2a) of the wind tunnel body (1) has a curved surface (5) smoothly expanding toward an outside of the wind tunnel body (1), and a collar-shaped brim having a width B is formed on an outside of an opening edge of an outlet (2b) for wind of the wind tunnel body (1).

  • Patent number: 6551085
    Abstract: A bladder for a vulcanizer includes, as a constituent member, a low elongation material with stable properties at vulcanization temperatures. During a vulcanization-molding process, the bladder is pressed against the inner surface of a green tire using a pressurized medium. The pressurized medium can be at vulcanization temperatures. The bladder has substantially the same shape as the inner wall surface of the tire that is formed using the bladder. As a result, irregularities in the shape of the inner wall surface of a tire rarely occur, and the frequency of exchange of bladders can be reduced. The vulcanizer bladder can include a conductive material or a magnetic material, both of which can be heated by using an induction heating coil. The use of both heat from the pressurized medium and heat generated in the bladder to vulcanize a green tire can shorten the period of time required for vulcanizing-molding.

  • Publication number: 20020047230
    Abstract: A method of operating a basic industrial plant complex efficiently utilizing energy, products, byproducts, and waste materials between the basic industrial plants as a whole to totally improve energy efficiency and contribute to energy saving. The basic industrial plant complex comprises basic industrial plants including an oil refining plant, an oil-fired power plant, a cement plant, a steelmaking plant constructed so as to be in close proximity to or adjacent to each other. The basic industrial plants are combined through a transporter for partially or completely supplying product, byproduct or waste material from a plant in the complex as a fuel, power source, and/or raw material to products for another plant in the complex.
