  • ANODIZED TITANIUM MATERIAL AND METHOD FOR PRODUCING THE SAME
    Publication number: 20210207283
    Abstract: An anodized titanium material includes a titanium base material and an anodized titanium layer. The anodized titanium layer is provided on a surface of the titanium base material. The anodized titanium layer includes a porous first anodized titanium layer. The anodized titanium layer has a withstand voltage at 25° C. of 500 V or more, a Vickers hardness of 200 or more, a film thickness of 20 ?m or more and less than 80 ?m, an arithmetic average roughness Ra of a surface of less than 1.6 ?m, and a maximum height roughness Rz of the surface is less than 6.3 ?m. In both of a section perpendicular to a thickness direction of the first anodized titanium oxide layer and the surface, no pore sections having a shape capable of including a circle having a diameter of 0.5 ?m or more are observed.

  • Particle collecting apparatus and particle collecting system
    Patent number: 10768089
    Abstract: A particle collecting apparatus includes a cylindrical housing, a gap forming unit, a supply port and an intake port. The cylindrical housing has a closed top and an open bottom facing a target object. The gap forming unit is configured to form a gap having a predetermined distance between the bottom and the target object. The supply port is formed at the opening of the bottom in an annular shape along an inner wall of the housing and configured to supply a gas to the target object. The intake port is provided closer to a central axis of the supply port than the supply port and configured to suck particles on the target object.
