  • Patent number: 4741373
    Abstract: A vehicle wheel and pneumatic tire arrangement. The tire has a radial carcass anchored in the tire beads, a tread strip, respective shoulder-like extensions which are each formed by a step, are disposed on each side of the tread strip, and do not come into contact with the roadway under normal driving conditions, and a belt which extends laterally to within the vicinity of each step extension to such an extent that a given one of the belt portions which is disposed within the vicinity of a given step extension has a width equal to approximately 25-40% of the amount by which the widest part of the tire extends beyond the end of the tread strip at that given step extension. To achieve a low rolling resistance and at the same time a great travel comfort, the beads of the tire are disposed axially inwardly on the rim to such an extent that the beads are disposed completely axially inwardly of the step extensions.

  • Patent number: 4738743
    Abstract: An apparatus for applying a tire material such as carcass ply to a molding drum in a tire molding process wherein the cut leading end of the ply is caused to pressure-adhere onto the molding drum by a leading-end applying and pressure-adhering roller. The molding drum is caused to rotate at an angle less than one rotation, and thereafter the ply is cut by the cutter mechanism, and the molding drum is further rotated to join the cut trailing end of the ply with the cut leading end, while the roller is pressure-adhering the cut trailing end of the ply against the molding drum.

  • Patent number: 4738748
    Abstract: A plasma processor, for dry etching during a fabricating process for an integrated circuit semiconductor device, including a plasma generating region formed in a waveguide into which microwave power is transmitted. An etchant gas is introduced into the plasma generating region and a plasma is generated. The plasma generating region and a reacting region are kept at a specific gas pressure differential by an evacuating device. The radicals (active etching species) react with the underside of a turned wafer placed on a base plate in the reacting region because the gas is blown against the underside of the wafer by the pressure differential. In particular, the wafer is etched by etchant gases floating the wafer by blowing the gases out of holes in the base plate. The floating wafer processing method provides a higher processing rate and better etching uniformity.

  • Patent number: 4737222
    Abstract: A tire building machine including flanges which have a surface to allow for the positioning and disengagement of a tire. The positioning and disengagement of the tire on the machine is effected by the surface interaction between the bead portions of the tire and the surface area of the flange. The surface area of the flange in the present invention includes a plurality of bead portion bearing surfaces to facilitate the release of the bead portions. In addition, the surface area of the flange is designed to reduce friction between the bead portions and the flange.

  • Patent number: 4737212
    Abstract: A method of interconnecting first and second material plies, each having one side coated with a thermoplastic material uses continuously rotatable pressing rollers and a heating gas. The marginal edge portion of an uncoated side of the first ply is folded back upon itself to form a pocket along its edge and after a strip having thermoplastic coating on each side is folded lengthwise, it is inserted into the pocket. The marginal edge portion of a thermoplastically coated face of the second ply is then positioned over the folded-over marginal edge portion of the first ply. Thermoplastic material between the folded-over portion of the first ply and the marginal portion of the second ply and between the folded portions of the strip are then heated so that they become plastic and they are pressed together to press the portions to be bonded together.

  • Patent number: 4737226
    Abstract: A method of manufacturing an automotive seat is disclosed which comprises the step of placing a trim cover assembly over a cushion member of foam material. In the method, a thermally weldable adhesive cloth is interposed between the trim cover assembly and the cushion member and is then welded by means of heating/pressure operation so that the trim cover assembly can be adhesively attached to the surface of the cushion member. Thus, the method provides such a seat that is improved in finishing as well as durability.

  • Patent number: 4734144
    Abstract: An annular band is positioned between a tire carcass and the crown portion. The band is comprised of individual laminate sheets that are pre-impregnated with a high fracture toughness resin that resists microtears. The individual sheets of the band are stitched together thereby enhancing the interlaminar shear resistance of the band. The curing process is expedited by co-curing the band, positioned in place, over the tire carcass. A plastic film covers the interface between the band and adjacent rubber to prevent contamination of the interface materials.
