  • Patent number: 6833821
    Abstract: The present invention provides a 3-dimensional wave-guiding structure for horn or tube-type waveguides. The wave-guiding structure comprises a fiber-reinforced composite material and a conductive nonwoven fabric shaped together with the composite material. The present invention also provides a 3-dimensional wave-guiding structure comprising a conductive nonwoven fabric 30 and a fiber-reinforced triaxial woven fabric 20 which are laminated alternately or in an arbitrary order. The conductive nonwoven fabric having flexibility can be readily shaped together with the composite material composed of a triaxial woven fabric or the like in conformity with the 3-dimensional shape of various horn or tube-like waveguides such as a waveguide diplexer, waveguide circulator, hybrid waveguide and waveguide directional coupler to provide a lightweight wave-guiding structure capable of achieving both excellent mechanical and electrical characteristics.

  • Publication number: 20040216177
    Abstract: Congenic rats are disclosed which express a truncated form of GPR10, wherein the truncation is the first 64 amino acids present in the NH2-terminus of wild-type GPR10. Also disclosed are in vitro screening methods for identifying compounds that bind to or modulate the function or expression of the truncated GPR10, and thus are useful in treating psychiatric diseases, such as depression and anxiety.

  • Patent number: 6291738
    Abstract: This invention provides holding and supporting appliances used in the fields of orthopedics, rehabilitation and sports and support members thereof that are light in weight, thin, rigid and durable and breathe well, and, furthermore, support members made of reinforced plastic triaxial woven fabrics impregnated with resin. The support members according to this invention include a piece formed of reinforced plastic triaxial woven fabrics. Preferably, the formed piece should have openings representing 5 to 33 percent of the overall area thereof, and a flexural rigidity of 10 to 1×104 kg·mm2 per unit width and a basis weight (weight per unit area) of 50 to 1000 g/m2. Holding and supporting appliances are formed by using the support members described above.

  • Patent number: 6154185
    Abstract: An antenna-oriented reflecting material using triaxial woven fabric is usable for frequency bands as high as 20-60 GHz. A reflecting material 1 usable for the high frequency bands is manufactured without spoiling advantages of triaxial woven fabric 2 by controlling mainly a construction n, a volume resistivity .rho. and a mass per unit length .eta. of the triaxial woven fabric. Particularly the setting of each parameter is determined by a composite model reflection ratio .GAMMA. obtained from a sum of a first reflection ratio .GAMMA.'s based on a surface resistance of the triaxial woven fabric and a second reflection ratio .GAMMA.p based on opening, holes of the triaxial woven fabric. It is preferable that a construction be 5-28 yards/in a mass per unit length .eta. be 10-460 tex g/1000 m, and a volume resistivity .rho. be 0.7 to 2.0.times.10.sup.-3 .OMEGA..multidot.cm.
