  • Patent number: 10914053
    Abstract: Provided is a work machine which makes it possible, in a hydraulic closed-circuit system, to prevent occurrence of cavitation when reverse lever operation which is an instruction for a swing in a direction opposite to a swing direction is performed during swing deceleration. A controller is configured to perform control such that a rate of a flow supplied from a bidirectionally tiltable hydraulic pump to a swing motor becomes lower than a pump flow rate according to an operation amount of the swing operation lever when a swing direction corresponding to a swing velocity sensed at a velocity sensor is different from a swing direction corresponding to operation of a swing operation lever.

  • Publication number: 20200370195
    Abstract: [Technical Problem] An object is to provide a heat insulation coat having a novel form/structure different from conventional ones. [Solution to Problem] The present invention provides a heat insulation coat having a spongy body that is composed of non-linear pores and a skeleton incorporating the pores. The skeleton is an amorphous body comprising Al, Si, 0, and impurities and has an amorphous peak specified by X-ray diffraction analysis at a position of 3.5 ? or more as the lattice spacing. The heat insulation coat has an apparent density of 1 g/cm3 or less, a volumetric specific heat of 1,000 kJ/m3·K or less, and a thermal conductivity of 2 W/m·K or less. The spongy body is obtained through forming a base layer, such as by thermal-spraying an aluminum alloy that contains a large amount of Si, and performing an anodizing process by AC/DC superimposition energization on the base layer. The amount of Si in the base layer may be, for example, 16 to 48 mass % with respect to the alloy as a whole.
