  • Patent number: 8195283
    Abstract: A pet body fat measuring tool and method for measuring pet body fat by measuring a bioelectrical impedance includes an electrode body including at least two current electrodes and at least two voltage electrodes. The electrode body is pressed to a part of a pet body. The tool also includes a control calculating unit having an impedance measuring circuit connected to the electrode body to control a current made to flow at a time of measurement. The control calculating unit includes, in advance of the measurement, a direct correlation between a body fat percentage of a pet body and the bioelectrical impedance of the pet body to calculate the body fat percentage based on only a bioelectrical impedance determined from measured voltages. A distance between each of the current electrodes and each of the voltage electrode is fixed.

  • Patent number: 6126365
    Abstract: A boring tool includes a concave groove formed on the outer peripheral surface of a tool body on the side opposite from a cutting blade with respect to an axis of the tool body. The concave, groove 10 is formed so as to extend from a position x, which is separated rearwardly from a front end face of a head portion, toward the rear side, and to be open downward from above a rake face. Furthermore, a sub-groove is formed between the concave groove and a chip pocket. Accordingly, the natural frequency is increased by reducing the weight of the head portion while limiting rigidity reduction, thereby restricting chattering.

  • Patent number: 5332339
    Abstract: A throw-away cutting tool is disclosed. The tool body of the cutting tool consists of a rod-like shank and a bit mounting component arranged at the front end of the shank. The shank is made of cemented carbide, and is formed with a mounting wall extending toward the front end of the tool body. The bit mounting component is made of steel or sintered metal, and is formed with a bit mounting seat defined by a bottom wall and side walls. In the above cutting tool, high resistance against the cutting force produced by cutting operation can be obtained and separation of the shank and the bit mounting component can be prevented; and high rigidity of the tool body is ensured, the damping capacity of the tool body is increased, and therefore vibration and chatter of the cutting tool can be effectively prevented.
