    Abstract: A control device to control a motor includes a stator including a coil, a rotor including a permanent magnet, a detector that detects a rotational position of the rotor at every predetermined angle and outputs a position signal indicating the detected rotational position, and a controller that receives the position signal output by the detector and adjusts a duty ratio of a driving signal of the rotor by a pulse width modulation scheme based on the received position signal to control rotation of the rotor. The controller raises the duty ratio from a first duty ratio, starting from a point in time at which the position signal is received, and returns the raised duty ratio to the first duty ratio when a next position signal has been received.

  • Method for manufacturing plate-like alumina powder and plate-like alumina powder
    Patent number: 10343928
    Abstract: 96 parts by mass of a ?-alumina powder, 4 parts by mass of a an AlF3 powder, and 0.17 parts by mass of an ?-alumina powder as a seed crystal were mixed by a pot mill. The purities of each raw material were evaluated, and it was found that the mass ratio of each impurity element other than Al, O, F, H, C, and S was 10 ppm or less. In a high-purity alumina-made sagger having a purity of 99.9 percent by mass, 300 g of the obtained mixed powder was received, and after a high-purity alumina-made lid having a purity of 99.9 percent by mass was placed on the sagger, a heat treatment was perforated at 900° C. for 3 hours in an electric furnace in an air flow atmosphere, so that an alumina powder was obtained. The value of AlF3 mass/container volume was 0.016 g/cm3.
