  • Patent number: 8293828
    Abstract: The present invention relates to using an adhesive and process for heating, curing, joining, attaching and detaching a part article from a body substrate structure. Described are polymeric adhesive compositions and methods of curing using a radiation apparatus for rapid adhesive bonding and attaching a fastener part to a structure surface. The adhesive composition contains additives that directly or indirectly absorb projected radiation from a radiation apparatus to rapidly and uniformly melt the adhesive and bond the surface of the part material onto the surface of the substrate material. A process is also described to reverse the adhesive bonding and detach the fastener part from the substrate.

  • Publication number: 20120148753
    Abstract: The present invention relates to a prepreg composite and to a process for manufacturing the prepreg composite. The manufacturing process involves surface treatment and impregnation of a high tenacity fibrous material with a surface treatment agent and a polymer matrix resin material. The fiber may be in the form of a woven, unidirectional or non-woven fabric. The fiber may optionally be coated with a surfactant and/or an adhesion promoter. Prior to treatment, the surface treatment materials may be contained in a dispersion of nano-particles in which each material has a film forming process temperature at a value below the degradation temperature of the fiber. The layers may be applied individually or simultaneously onto the fibers. The coated material is heat dried without compression to form a prepreg composite.

  • Patent number: 7375510
    Abstract: A rotational position sensor having a compact and simple structure, in which a magnetic surface can be formed to have a more accurate shape, and an electronically controlled throttle device for an internal combustion engine, which employs the rotational position sensor. The rotational position sensor comprises a pair of substantially half disk-shaped magnetic cores disposed in an opposed relation to each other with a magnetic sensitive device interposed therebetween, a pair of substantially arc-shaped magnetic cores disposed in an opposed relation to each other along outer peripheries of the half disk-shaped magnetic cores, and a permanent magnet fixed in contact with at least one of the arc-shaped magnetic cores. Magnetic flux generating from the permanent magnet flows successively through one of the arc-shaped magnetic cores, the half disk-shaped magnetic cores, and the other of the arc-shaped magnetic cores, followed by returning to the permanent magnet.

  • Publication number: 20060283543
    Abstract: A process for heating a polymeric material throughout its thickness using infrared electromagnetic radiation, whereby there is dispersed in the polymeric material throughout its thickness an infrared radiation absorbing agent in an amount such that at least a portion of the infrared radiation incident on the material from one side exits from the opposite side. The absorbed radiation may selectably vary from 1% to 99%; the particular percentage is calculated to rapidly heat the material to a temperature that depends on a particular application, and may be sufficient to soften the material so it can be pressure formed into a desired shape or, alternatively, high enough to melt this material when placed between two surfaces and used to the two surfaces together.

    Abstract: A throttle value spindle (3) is rotatably fixed to a throttle body (1). A recess is provided within the throttle body at one side of the throttle value spindle along the axial direction of the throttle valve spindle. A holder (6) is fixed to the throttle valve spindle within the recess and has brushes (7) at the opposite side of the throttle valve spindle, which rotates together with the throttle valve spindle. Resistors (12) are mounted on a ceramics circuit board (8) fixed on a housing (12). The housing engages with the recess in such a manner that the resistors contact with the brushes. When the brushes slide on the resistors corresponding to the rotation of the throttle value spindle, an electric signal is outputted continuously from the resistors.

  • Patent number: RE40523
    Abstract: A non-contact sensor for sensing a rotational position of a rotating object is provided. A ring-shaped permanent magnet magnetized in the axial direction is sandwiched between two pairs of magnetic plates from above and below. Two pairs of upper and lower protruded magnetic substance portions are provided between the upper and lower magnetic plates at opposite outer ends thereof. Magnetic sensitive devices are inserted in air gaps between the two pairs of upper and lower protruded magnetic substance portions. A magnetic flux generated from the ring-shaped permanent magnet is substantially concentrated to the protruded magnetic substance portions and passes the magnetic sensitive devices. The amount of magnetic flux passing each magnetic sensitive device is substantially proportional to the rotational angle of the ring-shaped permanent magnet.
