  • Patent number: 10744569
    Abstract: The present invention is directed to a surface-coated cubic boron nitride sintered material tool including a cBN substrate and a hard coating layer formed on a surface of the cBN substrate and having an alternate laminated structure of A layer and B layer. A peak of the grain size distribution of cBN grains in the cBN sintered material is present within a range of a grain size from 0.50 to 1.00 ?m. The A layer has a composition of (Ti1-xAlx)N (0.4?x?0.7 in an atomic ratio). The B layer has a composition of (Cr1-y-zAlyMz)N (0.03?y?0.6 and 0?z?0.05 in an atomic ratio). An X-ray diffraction peak of a (200) plane is present at a position of a diffraction angle of 43.6 plus or minus 0.1 degrees, and a plastic deformation work ratio of the B layer is 0.35 to 0.50.

  • Publication number: 20200210036
    Abstract: A touch input judgment device includes: a rotation direction judgment unit that determines a selection value change amount, to be added to a current selection value, when a rotation operation in a normal direction is inputted through a touch panel and stores rotation direction information in a storage unit when a rotation operation in the normal direction as a first rotation operation is performed; and a selection value change unit that sets a new current selection value after a change to a value obtained by adding a first selection value change amount to the current selection value when a rotation operation subsequent to the first rotation operation is a rotation operation in the normal direction and maintains the current selection value without change when the subsequent rotation operation is judged to be the return operation of the finger position.
