  • Publication number: 20080274147
    Abstract: The present invention is directed to a dry cleansing cloth that comprises at least one personal care composition imparted to the cloth, wherein the composition acts as a visual indicator of the compositions depletion with each use, eventually signaling the consumer for the need of a replacement cloth. Accordingly, the cloth of the present invention may be any suitable limited use substrate, including wovens, nonwovens, films, and combinations thereof. Preferably, the limited use cloth comprises a nonwoven substrate, wherein the nonwoven substrates may include, but are not limited to airlaid fabrics, wetlaid fabrics, spunlace fabrics, spunbond fabrics, meltblown fabrics, coform fabrics, entangled spunbond fabrics, and combinations thereof.

  • Publication number: 20070166970
    Abstract: A semiconductor process and apparatus fabricate a metal gate electrode by forming a first conductive layer (22) over a gate dielectric layer (11), forming a transition layer (32) over the first conductive layer using an atomic layer deposition process in which an amorphizing material is increasingly added as the transition layer is formed, forming a capping conductive layer (44) over the transition layer, and then selectively etching the capping conductive layer, transition layer, and first conductive layer, resulting in the formation of an etched gate stack (52). By forming the transition layer (32) with an atomic layer deposition process in which the amorphizing material (such as silicon, carbon, or nitrogen) is increasingly added, the transition layer (32) is constructed having a lower region (e.g., 31, 33) with a polycrystalline structure and an upper region (e.g., 37, 39) with an amorphous structure that blocks silicon diffusion.

  • Patent number: 7142779
    Abstract: A portable compact sauna wherein a user's body is warmed to sweating primarily by direct absorption of infrared radiation. Broad infrared radiation emitters or sources are placed around the inside of a narrow cabinet so as to be in close proximity to various parts of a seated user. Fins spaced apart less than finger-width on the emitters protect the user from contact with elevated temperatures in the emitters. The emitters, which lend themselves to easy cleaning, are heated by electric infrared heaters having a unique design which eliminates extremely-low-frequency (ELF) electromagnetic field (EMF) normally generated by AC energized electrical heater elements, to provide low extremely-low frequency EMF saunas able to utilize conventional-commercial electrical-energy sources. The emitters protect the heaters. Power wires for the heaters are arranged for low ELF EMF emission, too.

  • Publication number: 20060217000
    Abstract: The present invention is directed to a modular die unit comprising a plurality of individually shaped plates wherein the shaped plates are stacked in face to face juxtaposition, and when placed into such a juxtaposition exhibit useful polymer forming attributes heretofore unattainable by prior art practices. Single die plates are formed such that the plates exhibit a finite geometric relationship, which in turn provides resistance to flexural deformation of the individually shaped die plates and conversely, improved resistance to variability of the modular die unit and enhanced and predictable formation characteristics of the polymer material formed therewith. Each of said single die plates within the stack forming the modular die unit exhibit an x-direction, a y-direction, and a z-direction, wherein any one of said single die plates exhibit in said x-direction and y-direction to have at least a 50% planar continuity of the total planar continuity.

  • Publication number: 20050277296
    Abstract: A metal-containing semiconductor layer having a high dielectric constant is formed with a method that avoids inclusion of contaminant elements that reduce dielectric constant of metals. The metal-containing semiconductor layer is formed overlying a substrate in a chamber. A precursor is introduced to deposit at least a portion of the metal-containing semiconductor layer. The precursor contains one or more elements that, if allowed to deposit in the metal-containing layer, would become impurity elements. A reactant gas is used to purify the metal-containing layer by removing impurity elements from the metal-containing layer which were introduced into the chamber by the precursor.

  • Publication number: 20050277294
    Abstract: A method for treating a semiconductor surface to form a metal-containing layer includes providing a semiconductor substrate having an exposed surface. The exposed surface of the semiconductor substrate is treated by forming one or more metals overlying the semiconductor substrate but not completely covering the exposed surface of the semiconductor substrate. The one or more metals enhance nucleation for subsequent material growth. A metal-containing layer is formed on the exposed surface of the semiconductor substrate that has been treated. The treatment of the exposed surface of the semiconductor substrate assists the metal-containing layer to coalesce. In one embodiment, treatment of the exposed surface to enhance nucleation may be performed by spin-coating, atomic layer deposition (ALD), physical layer deposition (PVD), electroplating, or electroless plating.

Such materials, such as TaC and LaB6, can be formed to have work functions that are within approximately 4-4.3 eV, which is desirable for NMOS transistors. In addition, the amount of carbon or nitrogen can be adjusting the amount of carbon or nitrogen in the precursor to achieve a predetermined metal work function.

  • Publication number: 20030188405
    Abstract: The present invention is directed to a method of forming a nonwoven fabric, which exhibits a pronounced durable three-dimensional image, permitting use of the fabric in floor underlayment of laminate floor systems so as to reduce acoustic feedback under normal use (walking) due to sound absorption and leveling of the floating laminate floor system applications. In particular, the present invention contemplates that a fabric is formed from a precursor web comprising at least one support layer or scrim, whereby when subjected to hydroentanglement on a moveable imaging surface of a three-dimensional image transfer device, an enhanced product is achieved. By formation in this fashion, hydroentanglement of the precursor web results in a more pronounced three-dimensional image, an image that is durable to abrasion and distortion.

  • Patent number: 4555930
    Abstract: A digital gas sensing system comprises a plurality of satellite subassembly units each including a central processing unit (CPU) and a plurality of "intelligent" sensors connected to the satellite subassembly units by a single pair of leads. The satellite subassembly units communicate to the sensors in a code having a predetermined number of digital bits. Each sensor has internal "intelligence" and recognizes its own unique address and responds to the satellite subassembly unit in a predetermined code that varies from the satellite subassembly unit code by one parity bit. This arrangement makes it possible for other sensors to distinguish between transmissions from the satellite subassembly unit and transmissions from other sensors. The net result is that the system is able to operate very reliably using only two leads to connect all of the sensors to the satellite sub subassembly unit thereby greatly reducing the wiring and installation costs of the system.
