The state controller is connected to a pulse width modulation detection circuit, a timer, and a duty control controller. In accordance with another embodiment, a method for driving the motor includes coupling a single Hall sensor to the motor and using the single Hall sensor to determine a position of a rotor of the motor. The drive circuit pulls the rotor so that one of its north pole or south pole is adjacent to the single Hall sensor. After the pole of the rotor is adjacent to the rotor, the motor starts. | 06-25-2015 |

20140361164 | ELECTRON BEAM INSPECTION APPARATUS - An electron beam inspection apparatus includes an electron beam irradiating unit, an electric field generating unit, an energy analyzing unit, and a detection unit. The electron beam irradiating unit irradiates an electron beam on a sample. The electric field generating unit generates an electric field in an irradiation direction of the electron beam. The energy analyzing unit analyzes energy of electrons emitted from the sample caused by emission of the electron beam, where the electrons are accelerated by the electric field. The detection unit detects a depth position of a portion to which the electrons are emitted in the irradiation direction of the electron beam based on a result of the energy analysis. | 12-11-2014 |

20140369914 | ACIDIC GAS COLLECTION SYSTEM - A gas collection method comprises contacting a gas mixture including a weak acidic gas and a strong acidic gas with amine solution that absorbs a first portion of the gas mixture. After this first contacting step the gas mixture is contacted with amine solution that absorbs a second portion of the mixture. The amine solution after the second contacting step is heated to discharge at least some portion of the weak acid gas component absorbed therein. The method also includes adding an alkaline compound to the amine solution to generate a salt by reaction with the strong acidic component. The salt is separated from the amine solution and this amine solution can be used in the second contacting step. | 12-18-2014 |
