  • Publication number: 20220349152
    Abstract: Provided is a hydraulic piping clamp device for a construction machine, with which it is possible to easily assemble a plurality of clamp members used to fasten hydraulic piping. A fastener (5) includes a bracket (6) and a plurality of clamp members (7). Hydraulic hoses (4) are respectively held by the plurality of clamp members (7). Each clamp member (7) has a holding portion (71) for holding a hydraulic hose and an insertion hole into which a guide bar (65) can be inserted. The clamp members (7) are mounted on the bracket (6) by inserting the guide bar (65) into the insertion hole in the clamp members (7). When two adjacent clamp members move away from one another, a first engaging portion (73) of one clamp member engages with a second engaging portion (75) of the other clamp member.

  • Patent number: 10718722
    Abstract: Provided is a method of inspecting the back surface of an epitaxial wafer, capable of detecting pin mark defects in the back surface of the epitaxial wafer and quantitatively evaluating the defect size of individual point defects of the pin mark defects. The method of inspecting the back surface of an epitaxial wafer includes an imaging step of consecutively taking partial images of the back surface while moving the optical system using the scanning unit; an acquisition step of acquiring a full image of the back surface from the partial images; a detection step of detecting, in the full image, pin mark defects constituted by a set of a plurality of point defects present in the back surface of the silicon wafer 1; and a digitalization step of digitalizing the individual point defects to calculate the defect area of the individual point defects of the detected pin mark defects.
