  • Titanium alloy coating film and titanium alloy target material
    Patent number: 11834737
    Abstract: The titanium alloy coating film of the present invention is represented by (Ti1-aMoa)1-xNx, which satisfies 0.0423 a?0.32 and 0.40?x?0.60 and in which the film hardness thereof satisfies at least a condition of 3,000 HV or more; and the titanium alloy target material is represented by Ti1-aMoa, which satisfies 0.04?a?0.32, and in which, when an X-ray diffraction profile is measured on a surface of the target material, a diffraction peak intensity attributed to a single metal phase of Mo is not detected.
    Type: Grant

  • Key sheet and manufacturing method for key sheet
    Patent number: 7321103
    Abstract: As a key sheet for fixing a base sheet and key tops to be arranged on the base sheet using adhesive layers, a key sheet where the key tops and the base sheet are fixed, is obtained by forming printed adhesive layers of the key tops on facing surfaces of at least either of the key tops or the base sheet by means of printing, and then bringing the printed adhesive layer into contact with the other facing surfaces in a softened or molten state, and by curing the printed adhesive layer.
