  • Patent number: 6617097
    Abstract: The present invention aims at reducing the number of scanning exposure and at enhancing throughput. the above-mentioned objective is achieved by allowing a substrate 14 to be placed in sideways with respect to a substrate holder 15a (placing the longer sides of the substrate in parallel to the shorter sides of the substrate holder) depending on the size of the apparatus and the size of the substrate 14. It is acceptable even when areas other than an effective exposure area of the substrate 14 should project out from the substrate holder.

  • Patent number: 6557254
    Abstract: Metallic track members having locking slots designed for receiving and retaining metallic stud members that contain construction aids enable the assembly of metallic frames used in the construction of buildings. A flat metallic strip is converted to a W-shaped metallic track member by a series of stamping, bending and severing steps. U-shaped stud members, manufactured in a similar manner are inserted into the track members and held relatively stable by upper and lower track members. An upper track member can be the same shaped design as the lower member or can be U-shaped with stud retaining means into which the stud members can slip-fit. The process for manufacturing is adaptable for computer aided manufacturing using data from the computer aid design of the building. Manufacturing equipment for the manufacture of the construction members is relatively light-weight and can be transported to the job site.

  • Patent number: 6520722
    Abstract: Disclosed is a cutting tool with an asymmetric tooth form, and a method for making the same. Such tooth forms are useful for cutting tools such as band saw blades, circular saws, hacksaws and other saw type products. The tooth form of this invention can improve precision over prior art tooth forms by reducing manufacturing variability. The improved precision provides more consistent performance and a better quality of the cut surface. The non-symmetrical form ground tooth profiles cut designated chip profiles and thereby cut specific portions of the kerf much like a broaching application. This non-symmetrical ground tooth profile can alter the distribution of the downfeed cutting force allowing for more aggressive cutting or conversely, cutting at the desired rate with less downfeed pressure.

  • Patent number: 6494314
    Abstract: A unit dose, gas-filled syringe is provided which is filled with gas and packaged in a gas barrier material prior to use to increase shelf-life, that is, to minimize gas leakage and dilution of the contents of the syringe. The syringe is filled with a selected gas and sealed inside a container made from a high gas barrier material. The container is also filled with the selected gas. The container material is selected to have a gas transmission rate sufficient to prevent the selected gas from diffusing out of the container into the atmosphere. The volume of gas in the container is greater that atmospheric pressure to prevent atmospheric contaminants from entering the container and syringe.
