Abstract: A dynamic balancing apparatus and method using periodic angular motion are provided to implement balancing even when the weight of an object is too large to rotate by selectively applying the amplitude and frequency of angular motion. A dynamic balancing apparatus using periodic angular motion comprises a rotation shaft(10) in which a rotator(1) having rotating unbalanced mass is installed, a periodic angular motion generator(20) installed on the rotation shaft, supports(30) supporting both sides of the rotation shaft, and transducers(40) installed on the respective supports to measure the action force or vibration delivered to the supports by the angular motion of the rotation shaft. The periodic angular motion generator causes the rotation shaft to rotate at the specific angle periodically and vibrate due to the rotating unbalanced mass of the rotator.

Abstract: A method for monitoring a vacuum pump state is provided to obtain an exact state from a vacuum pump by checking main factors as references using an MPCA(Multiway Principal Component Analysis) statistical method. A first T^2 value is calculated from a normal state signal of a vacuum pump by using an MPCA based statistical method, wherein the normal state signal of the vacuum pump is obtained from a plurality of sensors. The first T^2 value is set as an UCL(Upper Control Limit), wherein the UCL is used as a reference for determining an abnormal state of the vacuum pump. A second T^2 value is calculated from an abnormal state signal of the vacuum pump by using the MPCA based statistical method. The UCL and the second T^2 value are compared with each other in order to check an exact state of the vacuum pump.

Abstract: PURPOSE: A conversion method of a specific value for a space sound phase localization and a method and apparatus for recording a three dimensions sound using the conversion method are provided to localize and reproduce a sound in a three dimensions space. CONSTITUTION: If a relative space information of a listener and a sound source is set, a setting value of an equalizer by bands of left and right sides sound channels is decided from a sound pressure level database of left and right side ears. Gain rates of the left and right sides sound channels are adjusted using the setting value. Equalizer output signals(EQL(t),EQR(t)) coding a difference of a sound pressure level of both ears needed at a space sound phase localization with respect to the inputted sound source(S(t)) are obtained using the left and right equalizer. A setting value of a difference of a sound pressure reaching time of the both ears is decided in accordance with the setting space information. A relative relay time is set at a channel being tardily reached to the sound pressure out of the left and the right directions. In the case that a sound pressure reaching time of the right channel is late, that is, sound source is positioned at the left side of the listener, if an output signal of the equalizer is inputted, a time relay device outputs the EQL(t) signal and the EQR(t-TLR) signal.
