  • Publication number: 20180269168
    Abstract: A module substrate includes a surface layer to which a rectangular waveguide structure having a waveguide aperture is to be connected; metal layers stacked with a dielectric layer between each pair thereof and including a first metal layer that includes a transmission line and a coupling element at a portion of the transmission line and a second metal layer positioned further than the first metal layer from the rectangular waveguide structure; and vias connecting the adjacent metal layers. The surface layer has a first opening facing the waveguide aperture. The first opening surrounds the coupling element in plan view from the surface layer. A dielectric layer region surrounded by some of the vias is formed within a projection area of the first opening between the first and second metal layers. The region has a size smaller than the waveguide aperture in the plan view.

  • Publication number: 20160009908
    Abstract: Solved is the following problem: a PE based resin including a film grade ethylene-?-olefin copolymer is excellent in economic efficiency, but has a narrow molecular weight distribution in consideration for strength and heat sealability, and therefore causes surface roughening to occur when applied to a covering material for an insulated electric wire or cable. Applied is a polyolefin based resin composition including at least one polyethylene (PE) based resin, in which, when a ratio (I10/I0.5) of an MFR (I10) measured at 190° C. and a load of 10 kg to an MFR (I0.5) measured at 190° C. and a load of 0.5 kg is defined as MFRR, a difference between the MFRR of the polyolefin based resin composition including at least one PE based resin and the MFRR of the PE based resin is 5 or more.

  • Publication number: 20150357081
    Abstract: Solved is the following problem in terms of outer appearance: a covered electric wire obtained by extrusion of a low cost linear polyethylene resin (LLDPE) has irregularities formed on the surface thereof because processing suitability of LLDPE is poor. As a solution to the problem, a resin composition including 50 to 97 parts by weight of LLDPE and 3 to 50 parts by weight of a polypropylene (PP) based resin can be used to thereby produce a covered electric wire excellent in surface smoothness at a high speed and a low cost.
