Abstract: A scratching detection system includes a sensor and processor. The sensor is configured to detect acceleration corresponding to movement of a person's hand and is configured to output a first signal including a detected value corresponding to the acceleration in a first cycle. The processor is configured to acquire the first signal and to detect a scratching behavior of the person in a second cycle based on a plurality of parameters. The second cycle includes a plurality of the first cycles. The plurality of parameters includes a first occurrence count and a first consecutive count. The first occurrence count is a number of times an absolute value of the detected value exceeds a threshold value in the second cycle. The first consecutive count is a maximum value of a number of times that the absolute value of the detected value consecutively exceeds the threshold value in the second cycle.

Abstract: A planar heating element using for carbon micro-fibers and its manufacturing method have developed. The high-resistant carbon micro-fibers and carbon powder are efficiently coated to completely replace a conventional heating element using resistance heat of a nichrome wire. A single heating element is possibly formed to have a large width and an ultra thin heating element without temperature restriction by overcoming drawbacks of a carbon powder printed heating element serving as an initial module of the planar heating element. Thus, it is possible to produce the various convenient heating elements or heating modules using DC and AC electricity without restriction by solving problems in installation and use, for example, space restriction, thereby various convenient heating elements.

Abstract: A mounting system for rotating tools such as grinding wheels in a hand-held power tool, includes a hub mountable to the tool drive shaft and a rotating tool element removably affixable to the hub. The tool has at least one flange that engages a corresponding circumferential groove in a hub wall. Both the hub and tool have complimentary lock elements to frictionally retain the tool in a releasably fixed orientation upon the hub. One of the lock elements is in the form of a depression, while a mating element located on the other ports is a complimentary projection.

Abstract: A cutting tool in which a disc-like cutter blade is fixed to a spindle of a rotary electric tool, comprising a first guide plate, which is attached on electric tool side to a cutter blade such that it is capable of rotating freely and makes contact with the reference surface of a cutting object material on a process of cutting progress so as to guide along a cutting direction, an inner flange located between the first guide plate and the cutter blade so as to specify a distance X from the reference surface of the cutting object material to a cut groove and a second guide plate which is provided on an opposite side to the electric tool side of the cutter blade and makes contact with a cut face of the cutting object material on a process of the cutting progress so as to stop moving in the cutting direction to specify a cut groove depth Y.

Abstract: A height adjustment mechanism for varying the positioning of a rotating tool on a haft of a machine tool, such as a portable power tool, is in the form of a coupler between the blade and tool arbor. A head of the coupler accepts the tool and connects with a tool drive, the depth of the connection defining the working height or position of the tool. A pair of inter-engaged flanges are mounted upon the shaft of the coupler head, and apply forces to the coupler head and tool drive to maintain the connection depth therebetween and to retain the tool in position. A jam nut further maintains the relative orientation of the flanges.

Abstract: A blade-mounting adaptor for a power tool has a blade-mounting stud on which the blade is mounted at a first end. The blade is mounted upon the stud in a manner such that it is capable of axial motion along the length of the stud when exertion is applied to the blade. The blade is provided with an adjustable pre-set bias force against the axial motion.

Abstract: A hybrid three-axis magnetic sensor for calculating the accurate direction of the earth magnetism. The hybrid three-axis magnetic sensor includes: a flux gate type magnetic sensor which is so formed that a base serves as a main member and detects two axis components of a magnetic vector defined by a plane parallel to the base; a Hall element which detects another component of the magnetic vector orthogonal to the base; a tilt sensor which detects a tilt angle of the base; and a CPU, wherein the flux gate type magnetic sensor and the Hall element are integrally structured together as a hybrid IC. The thus detected three dimensional magnetic vector is corrected in the light of inclination of the base, so that the direction of the earth magnetism is accurately calculated.
