  • Patent number: 5674574
    Abstract: A vapor delivery system for vaporization and delivery of a solid precursor includes a housing having an inlet for receiving a carrier gas. A rotatable substrate surface is contained in the housing having a solid precursor material applied thereon. A focused thermal beam is positioned for impingement on the solid precursor material. A drive mechanism moves one of the rotatable surface and the focused thermal beam relative to the other such that with rotation of the rotatable substrate surface the focused thermal beam continuously impinges on a different contact area of the solid precursor material for vaporization thereof. The housing further has an outlet for transport of the vaporized precursor material therefrom. The rotatable surface may be a cylindrical surface or a circular platen surface. A CVD system having a vapor delivery system is also provided along with a device for use in the delivery system.

  • Patent number: 5667031
    Abstract: A snowmobile construction comprising a body frame and having slide rails suspended from the body frame through a front and rear suspension arm, and an endless track which runs under tension upon a drive and a plurality of driven wheels rotatably borne on the slide rails. The rear suspension has front and rear suspension arms which connect the body frame and the slide rails in parallelogram linkage fashion. Compression coil springs and shock absorbers are operatively mounted between the slide rails and the front and rear suspension arms. An inclined slide block and slot coupling interconnects the rear suspension arm and each slide rail to automatically react both front and rear suspension arms upon initial encounter of the slide rails with a snow bump at either end of the slide rail. This coupling also urges the snowmobile into an upwardly pitched condition upon acceleration with the forward ends of the slide rails digging into the ground surface for enhanced traction.

  • Patent number: 5654364
    Abstract: The invention relates to melt-miscible polyolefin blends, and a process for preparing the melt-miscible blends, of two or more polyolefins. Matching of the segment length of a modifying polyolefin with the segment length of a primary polyolefin, such as polypropylene or an ethylene/alpha-olefin copolymer, provides polyolefin blends heretofore unknown to be melt-miscible. A broad range of polyolefin blend compositions, and of polyolefin blends containing other polymers made compatible with the polyolefin blend compositions, are defined, all of the blend compositions having at least one melt-miscible polyolefin phase.

  • Patent number: 5651860
    Abstract: A method of removing a resist layer formed on a substrate wherein the resist layer includes an ion-implanted upper region. The method includes hydrogenating the ion implanted upper region of the resist layer resulting in the hydrogenated ion-implanted upper region. The resist layer, including the hydrogenated ion-implanted upper region is then removed. A hydrogenation of the ion-implanted upper region may be performed by immersing the resist layer, including the ion-implanted upper region, into pressurized boiling water, and/or treating the ion-implanted upper region with pressurized water vapor.
