  • Publication number: 20190346482
    Abstract: A test carrier carried in a state of accommodating a device under test (DUT) includes: a carrier body that holds the DUT; and a lid member that covers the DUT and is attached to the carrier body. The carrier body has contactors provided to correspond to terminals of the DUT, external terminals electrically connected to the contactors, and a first through-hole for positioning that is provided to face the DUT. The first through-hole penetrates the carrier body so that a part of the DUT is seen from an outside through the first through-hole.

  • Publication number: 20150118036
    Abstract: An annular fan case which covers an outer periphery of a fan in an aircraft engine includes: a case body including a first composite material containing a fiber and a resin; and a containment section including a second composite material containing a fiber and a resin, the containment section being formed on an outer periphery of the case body. A resin content of the containment section is set to be lower than the resin content of the case body.

  • Patent number: 7838156
    Abstract: A thickener for use in an alkaline battery provides a gel viscosity ratio (N1h/N12h) of 0.7 to 1.3, the gel viscosity ratio (N1h/N12h) being a ratio of a viscosity (N1h) of a gel after being left to stand for one hour to a viscosity (N12h) of the gel after being left to stand for twelve hours (where the gel viscosity is a viscosity of a gel composed of 2.0 parts by weight of the thickener, 200 parts by weight of zinc powder, and 100 parts by weight of 37 wt % aqueous solution of potassium hydroxide, measured at 40° C. according to JIS K7117-1: 1999). An alkaline battery having a negative electrode gel in which the thickener of the present invention is used is provided. The alkaline battery exhibits improved long-term retention of discharge characteristics (discharge amount and discharge time), and improved impact resistance.

  • Patent number: 7579115
    Abstract: A gelling agent for use in an alkaline battery comprises a cross-linked polymer (A) formed with a (meth)acrylic acid (salt) as a principal constituent monomer unit, wherein the gelling agent allows an obtained gel (GA) to have a viscosity ratio (N1/N60), determined as follows, of 0.7 to 1.3, and includes components soluble in 37 wt % aqueous solution of potassium hydroxide that account for 30 wt % or less of the gelling agent: the viscosity ratio (N1/N60) of the gel (GA) is determined by preparing the gel (GA) by stirring 100 parts by weight of 37 wt % aqueous solution of potassium hydroxide, 2 parts by weight of the cross-linked polymer (A), and 200 parts by weight of zinc powder at 40° C. so as to be mixed uniformly, and measuring a viscosity (40° C., N1) of the gel (GA) after being left to stand at the same temperature for one day, and a viscosity (40° C., N60) of the gel (GA) after being left to stand at the same temperature for sixty days, according to JIS K7117-1: 1999.
