    摘要： It is an object of the present invention to provide a cutting tool in which excellent electrical conductivity between a tool substrate and a workpiece can be realized even when the tool substrate is clad with a diamond film, and with which it is possible to precisely control the hole boring depth or precisely sense breakage by using the electrical conductivity. An electroconductive film (3) is provided to a diamond film (2) at a site that will make contact with a workpiece or around the site so as to conduct electricity with a tool substrate (1).

    摘要： An object of the present invention is to provide an atrial fibrillation detection system in which: the extent of irregularity in measured pulse intervals is calculated; even in cases where an extrasystole has occurred, detection of a false positive is reduced even when the extrasystole is not excluded; and highly reliable assessment results are obtained. An atrial fibrillation detection system comprising: pulse interval measurement means 4 that measures the pulse intervals of a heart; pulse interval conversion means 8 that performs conversion, using a prescribed function; entropy computation means 9 that calculates entropy S from pulse interval images r obtained through conversion by the pulse interval conversion means 8; and comparative assessment means 10 that compares the entropy S calculated by the entropy computation means 9 and a threshold value, and that, in cases where the entropy S is greater than the threshold value, assesses that atrial fibrillation is occurring.

    摘要： Provided is a ball end mill which is capable of performing both cutting and polishing well and in which cutting resistance at a tip part is low. A ball end mill formed with a plurality of chip discharge grooves 2 on an outer periphery of a tool body 1 from a tool tip toward a proximal end side, and provided with ball-nosed end cutting edges 5, 6 on a crossing ridgeline part between a rake surface 3 of the chip discharge grooves 2 and a spherical tip surface 4 of the tool body 1, said ball end mill having a tool rotation center O on the spherical tip surface 4 and a center-nearing ball-nosed end cutting edge 5 set so that a distance X from the tool rotation center O to the point closest to the tool rotation center O on one ball-nosed end cutting edge 5 in a view of the tool tip is shorter than a same distance Y to the other ball-nosed end cutting edge 6.

    摘要： The present invention provides a more practical hard-coated cutting tool having improved cutting performance during finishing so as to obtain a better finished surface. Provided is a hard-coated cutting tool including a tool body (7) coated with a hard coating (4) and having a cutting edge (3) formed on a ridge line intersecting a flank face (1) and a rake face (2). In the hard-coated cutting tool, the thickness h1 of the hard coating (4) on the flank face (1) side and the thickness h2 of the hard coating (4) on the rake face (2) side near the cutting edge (3) satisfies conditions 8 µm ‰¤ h1 ‰¤ 30 µm and 0 ‰¤ h2/h1 ‰¤ 0.5 in a cross-section perpendicular to the cutting edge (3) in a range equal to or less than 0.3 times the tool diameter in the axial direction from the tip of the tool.
