    摘要： At least one groove and two grooves extending toward an axial direction of a rotor and is provided on an outer periphery of a rotor iron core or at least one hole is provided in the rotor iron core. By providing the groove and the two grooves on the outer periphery of the rotor iron core or by providing the hole in the rotor iron core, cogging torque is generated to negate the cogging torque which is generated according to the magnetic fluctuation between the magnetic field of the permanent magnets and a stator. As a result, the overall cogging toque in a permanent magnet type rotary machine is reduced.

    摘要： In a terminal device, when application screens of a plurality of types of applications are being displayed individually and the display directions thereof differ from each other, a control section selects any one of the plurality of types of applications as a reference for display control, and orients the display direction of an application that is not the control reference to the display direction of an application that is the control reference. That is, when the display direction of an application displayed on one display section is changed from a vertical direction to a horizontal direction, the display direction of an application displayed on another display section is changed from the vertical direction to the horizontal direction so as to follow the foregoing change.

    摘要： The sintered magnet and the rotating machine equipped with the same are disclosed. The sintered magnet includes crystal grains of a ferromagnetic material consisting mainly of iron, and a fluoride compound or oxyfluoride compound layer containing at least one element selected from an alkali metal element, an alkali earth metal element, and a rare earth element. The layer is formed inside some of the crystal grains or in a part of a grain boundary part. An oxyfluoride compound or fluoride compound layer containing carbon in a stratified form is formed on an outermost surface of the crystal grains. The fluoride compound or oxyfluoride compound layer has a concentration gradient of carbon, contains at least one light rare earth element and at least one heavy rare earth element. The heavy rare earth element has a concentration lower than that of the light rare earth element.

    摘要： Disclosed herein is a sintered magnet motor having a sintered magnet rotor, the rotor comprising: a ferromagnetic material comprising iron as a main ingredient to be sintered; a fluorine compound or an oxyfluoride compound formed in the inside of a crystal grain or to a portion of a grain boundary of the ferromagnetic material; and at least one of alkalis, alkaline earth elements, and rare earth elements contained in the fluorine compound or the oxyfluoride compound; a portion of the fluorine compound or the oxyfluoride compound being distributed with a concentration gradient established from the surface to the inside of the ferromagnetic material, and a rare earth element being distributed with a concentration gradient established between the grain boundary surface and the parent phase of the ferromagnetic material, wherein the concentration distribution of the fluorine compound is asymmetrical when viewed from the pole center of the sintered magnet rotor. The amount of use of a fluorine compound can be decreased in this sintered magnet motor.
