  • Publication number: 20180180068
    Abstract: A hydraulic system for a working machine includes a hydraulic actuator having a first fluid chamber and a second fluid chamber, an accumulator, an outputting fluid tube to output an operation fluid, and a switching valve to be switched between a first position and a second position. The first position allows the first fluid chamber and the second fluid chamber to be communicated with the outputting fluid tube and thereby allowing a floating operation. The second position allows the first fluid chamber and the accumulator to be communicated with each other, allows the second fluid chamber and the outputting fluid tube to be communicated with each other, and thereby allows an anti-vibration operation.

  • Patent number: 9919501
    Abstract: A method of manufacturing a cleaning member includes a fiber bundle conveying step conveying a fiber bundle to a merging section, a nonwoven fabric conveying step conveying the nonwoven fabric strips to the merging section; a multilayer web forming step forming a multilayer web by overlaying the fiber bundle on the nonwoven fiber strips at the merging part; and a joining step joining the fiber bundle and the nonwoven fabric strips to each other in the multilayer web. In the fiber bundle conveying step, the fiber bundle is conveyed at a tension at which there is no width shrinkage in the fiber bundle, and in the multilayer web forming step, the multilayer web is formed by overlaying the fiber bundle on the nonwoven strips while applying a tension that does not cause width shrinkage in the fiber bundle.

  • Patent number: 9809750
    Abstract: A liquid crystal composition contains liquid crystals containing one kind of or two or more kinds of silicone surfactants, a phenyl-modified silicone oil and water. The liquid crystal composition of the present invention contains 5 to 95% by weight in total of one kind of or two or more kinds of silicone surfactants, 0.1 to 90% by weight of a phenyl-modified silicone oil and 0.1 to 90% by weight of water. The liquid crystal composition of the present invention can solubilize hydrophobic compounds having poor solubility (for example, hydrocarbon oils such as squalane, fatty acids such as oleic acid and lipoic acid and ester oils such as cetyl isooctanoate) and is thus useful, for example, as toiletry materials and cosmetic materials.
