  • Patent number: 6744070
    Abstract: In a thin-film transistor to be used in an active matrix liquid crystal display device, each of a gate signal line, a source signal line, and a drain extraction electrode has a three-layer structure. Specifically, each of these members is made up of a lower layer made of a titanium film, an intermediate layer made of an aluminum film, and an upper layer made of a titanium film containing nitrogen. Since the respective upper layers, in contact with a gate insulating film or an interlayer insulating film made of a silicon nitride film, are made of titanium films containing nitrogen, they have superior adhesion to the silicon nitride film. Consequently, film peeling, etc. during the manufacturing process can be suppressed. Further, providing the titanium film beneath the aluminum film contributes to reduction of the resistance of the aluminum film.

  • Patent number: 6698909
    Abstract: The invention provides in preferred aspects architectural lighting structures that comprise a plurality of tubular elements at least partially embedded into an at least substantially transparent lens structure of a lighting fixture. The lighting fixture is typically a device employed for interior use, particularly residential buildings or commercial buildings such as office buildings. By partially embedding the array or plurality of tubular elements into the transparent lens structure, the fixture can appear as if it is substantially a part of the surrounding surface when the lighting fixture is turned off. Nevertheless, when the light is turned on, light coming from the fixture can still be directed or modified in an appropriate manner, e.g. without detrimental light output reductions), and without the need of an expensive, sophisticated reflector or any necessity of the fixture extending beyond the surrounding surface as has been utilized in certain prior attempts to mask architectural lighting fixtures.

  • Patent number: 6665043
    Abstract: A substrate bonding method in which a pair of masks which were prepared by forming a recessed section at a center part of each flat plate are placed on upper and lower stages, respectively, so that the recessed sections face a CF substrate and a TFT substrate, the CF substrate and TFT substrate are positioned one upon another and bonded together by sandwiching them between the masks. With this method, not only the CF substrate and TFT substrate are protected by the recessed sections from both sides, but also the dimensions of a region of each of the CF substrate and TFT substrate protected by the recessed sections are easily changed by replacing the masks. It is thus possible to provide a substrate bonding method that can readily meet the manufacture of bonded substrates of a variety of dimensions.

  • Patent number: 6610396
    Abstract: A resin molding product of the present invention is a sandwiched molding product provided with a core layer and a skin layer having at least an electrophotographic toner. Further, it is preferable that the core layer contains an additive resin, which is compatible with a binder resin that is used for the electrophotographic toner and can give an elasticity to the core layer when the additive resin and the binder resin are dissolved with each other. According to the arrangement, it is possible to utilize as a raw material a nonstandard toner, which is produced during a manufacturing process of the electrophotographic toner, but cannot be used as a commercial product, and a discard toner, which has been used in an image forming apparatus of an electrophotographic method, thereby realizing a resin molding product of a high quality at a low cost, while the resin molding product can improve its impact resistance by use of the additive resin.

  • Patent number: 6605223
    Abstract: An automated blood separation method and apparatus is described that allows for the separation of multiple units of blood simultaneously. The method and apparatus reliably and quickly separates blood into its components. An auto-balancing feature within the apparatus automatically preferably compensates for the changing state of imbalance, thereby eliminating the need for additional balancing steps during the separation process. The apparatus has a rotor into which a plurality of cassettes can be inserted. The cassettes have a number of sections for the containment of the whole blood and for the separated blood components, which are contained in disposable bags. The rotor is placed into a centrifuge assembly, and the blood components are then separated and transferred to the bags in the individual sections of the cassettes. Means for including secondary separation devices such as filters is included.
