  • Publication number: 20200303708
    Abstract: A secondary battery includes an electrode assembly including a positive electrode, a negative electrode, a first separator disposed on one side of the surface of the negative electrode and having a thickness T1, and a second separator disposed on the other side of the surface of the negative electrode and having a thickness T2. The thickness T2 of the second separator is larger than the thickness T1 of the first separator. The first separator includes a first porous film having a porosity P1, and the second separator includes a second porous film having a porosity P2. At least one of the first separator and the second separator includes a heat resistant layer. The positive electrode, the first separator, the negative electrode and the second separator are wound together such that the first separator is arranged on the outer side and the second separator is arranged on the inner side.

  • Patent number: 10704976
    Abstract: A pressure sensor according to the present invention includes a diaphragm (3) including a first principal surface (3A) and a second principal surface (3B) that is opposite thereto, the first principal surface receiving a pressure of a fluid; a semiconductor chip (1) provided with resistors that constitute a strain gauge; and at least three support members (2a, 2b, 2c) made of an insulating material, each support member being fixed to the second principal surface at one end thereof and to the semiconductor chip at the other end thereof and extending perpendicularly to the second principal surface so as to support the semiconductor chip. One of the support members (2a) is provided at a center (30) of the diaphragm in plan view.

  • Patent number: 10538157
    Abstract: Provided is a work vehicle in which a seat support frame that supports a driver seat is equipped on a vehicle body frame, the vehicle body frame includes: a front portion vehicle frame at which a floor surface of a driving portion is provided; and a rear portion vehicle frame disposed at a position higher than the floor surface of the driving portion and rearward of the front portion vehicle frame. An engine is equipped below the rear portion vehicle frame, a battery that supplies power to an electric motor is equipped above the front portion vehicle frame and below the seat support frame, and a frame portion of the seat support frame that exists above the battery at a position opposing the battery is configured to be detachable from another frame portion that is fixed to the vehicle body frame.

  • Publication number: 20180297329
    Abstract: A metal-clad laminate includes an insulating layer including a cured product of a resin composition, and a metal foil disposed on a principal surface of the insulating layer. The resin composition includes a polyphenylene ether copolymer and a thermosetting curing agent, the polyphenylene ether copolymer having an intrinsic viscosity measured in methylene chloride at 25° C. of between 0.03 dl/g and 0.12 dl/g, inclusive. And the polyphenylene ether copolymer has, at a molecular terminal, a group represented by formula (1) or formula (2) at an average number of 1.5 to 3 per one molecule. Further, the metal foil has a first surface that is in contact with the insulating layer, the first surface having a 10-point average roughness (Rz) of 2.0 ?m or less. And the metal foil includes a barrier layer disposed at a side of the first surface, the barrier layer containing cobalt.
