  • Patent number: 7726940
    Abstract: Assembly of segmented seals can be problematic in areas of limited space for an introductory tapered mandrel and where there are the problems with damage to the seal surfaces 23, 24. By the present method and arrangement, a seal formed from segments 22 is expanded to an expanded state and then retained at that state by the use of a sacrificial material 26 in the gaps 25 between the segments 22 opened by expansion. The sacrificial material 26 is typically a low melting temperature wax and so is removed when the seal arrangement reaches its operating temperature.

  • Patent number: 7614138
    Abstract: The method according to the present invention and the device (1) used to implement the method for wrapping or enveloping a galosh which is also named as an overshoe, around a footwear, have been developed in order to avoid the bacteria, microbes, dust, mud and other dirt particles that may be found on the soles of the footwear, from being carried into and the areas with hygienic requirements. With the device (1), the sole and the side walls (side vamps) of the footwear are wrapped with a film (21) by a method, wherein warm air is blown at a suitable flow rate towards the sole and side vamps of the footwear, which causes the film (21) to shrink and cover the solve and side vamps of the footwear by wrapping them up when it comes into contact with the film.

  • Patent number: 7562433
    Abstract: A method for fabrication of nanometer scale metal fibers, followed by optional further processing into cables, yarns and textiles composed of the primary nanofibers. A multicomponent composite is first formed by drilling a billet of matrix metal, and inserting rods of the metal desired as nanofibers. Hexed or round rods can also be inserted into a matrix metal can. The diameter of this composite is then reduced by mechanical deformation methods. This composite is then cut to shorter lengths and reinserted into another billet of matrix metal, and again the diameter is reduced by mechanical deformation. This process of large scale metal stacking followed by mechanical deformation is repeated until the desired fiber size scale is reached, the fibers being contained in the matrix metal. After size reduction, the composite metal wires may be further processed into built up configurations, depending on intended application, by stranding, cabling, braiding, weaving, knitting, felting, etc.

  • Patent number: 7513041
    Abstract: A nozzle plate includes a nozzle surface and a nozzle hole. The nozzle surface defines an ink ejection port. The nozzle hole includes a taper hole portion and a curved-surface hole portion. The taper hole portion has an inner surface of a truncated conical shape and has the smallest diameter at one end thereof. The curved-surface hole portion has an inner surface of a curved-surface shape. The inner diameter of the curved-surface hole portion gradually decreases as approaching from the one end of the taper hole portion to the ink ejection port.

    Abstract: A method and apparatus are provided for total profile machining of a part, such as from a block of thermoplastic polymer. A first side of the part is machined together with an encircling recess. A registration/potting fixture is placed into the encircling recess. The registration/potting fixture is used to evacuate air from the machined side of the part and to pressure pack degassed fluid potting compound against the machined side of the part. The registration/potting fixture is cooled such as with a coolant to solidify the potting material. Then the registration/potting fixture is used to fixture the block in a new orientation for CNC machining another side of the part. Upon removal of the potting material from the part, the total profile machined part is freed for shipment to the customer.

  • Patent number: 7257281
    Abstract: A method for fabricating thick film alumina structures used in high frequency, low loss applications is provided. More particularly, the invention is directed to a co-fire process for fabricating, or laminating, thick film structures to one another by printing a conductor layer between two thick film circuits, drying the layer, and co-firing the combined structure. This process is particularly useful in fabricating high frequency (e.g. 10 gigabit) fiber optic transmitters.

    Abstract: A print head manufacturing method in which satisfactory precision can be obtained by simple processes are provided. Projecting objects having a predetermined shape are formed on a substrate, and a setting resin is applied on the substrate and is set. Then, the projecting objects are removed so that ink cells and nozzles are formed. The thickness of the setting resin is determined such that tip portions of the projecting objects project above the setting resin and ink cells can be formed.

  • Patent number: 7165307
    Abstract: There are disclosed a method and apparatus for applying a strippable paint to a large-sized product finished with a sprayed coating, such as an automobile, to form a protective film on the surface of the coating. The product is conventionally kept in stock for a period of time before it is shipped. Contaminations such as dust are washed away from the surface of the product. Then, the strippable paint is applied, preliminarily dried, and non-preliminarily dried to form the protective film out of the strippable paint on the surface of the coating. This protective film is formed easily, appropriately, and reliably. The obtained protective film has a uniform and sufficient thickness. Even if the surface contains unapplied regions to which the paint should not be applied, the paint can be applied to the whole surface of the coating while avoiding the unapplied regions according to the invention. The application can be performed easily and reliably without leaving unapplied portions around the unapplied regions.
