Title: Harmonics removing circuit, position detector, magnetic bearing device, and vacuum pump
Inventor: KAWASHIMA TOSHIAKI
IPC: F16C32/04
Filed: 2020-02-17
Abstract: To provide a harmonics removing circuit, a position detector, a magnetic bearing device and a vacuum pump, with which harmonics occurring to a synchronous detection circuit are removed without using expensive components and low vibration, low noise are thereby realized.SOLUTION: The odd-numbered harmonics of a sensor carrier frequency can be removed from a displacement signal after detection by setting the duty cycle of a switch of a synchronous detection circuit to a specific value. A condition for a pulse generation method basically is to adjust so as to generate pulses with a phase angle of 180 degrees + 360 degrees × n (n=positive integer including 0). Meanwhile, the duty cycle of pulses of synchronous detection switch should be set so that the positive-side area and the negative-side area of harmonics waveform are equal. The duty cycle of pulses should be adjusted so that a phase angle at which the sensitivity of the sensor signal is largest is central. Namely, it is desirable that if the sensor signal is a 360-degree sinusoidal wave, the duty cycle of pulses be adjusted centering on a 90, 270-degree phase angle.SELECTED DRAWING: Figure 1

Inventor: KONNO AI
IPC: B63B83/40
Filed: 2020-02-18
Abstract: To provide heating structure of an exhaust gas treatment unit which can properly heat the exhaust gas treatment unit, and can be easily constructed and maintained.SOLUTION: Heating structure 50 heats an exhaust gas treatment unit 30 by using a heated fluid F which is generated by a heated fluid generation unit 80. Therefore, the heating structure 50 can heat the exhaust gas treatment unit 30 without using a member which is difficult in construction and maintenance like an electric heater 101. That is, trouble due to the electric heater 101 which has been explained in a comparison example does not occur since the heating structure 50 uses the heated fluid without using the electric heater 101 for heating. Also, the heated fluid generation unit 80 is equipment generating the heated fluid in a ship 100 at timing at which at least a main engine 16 is operated. Therefore, as far as the timing is one at which an exhaust gas G is discharged from the main engine 16, the heating structure 50 can heat the exhaust gas treatment unit by using the heated fluid at any time.SELECTED DRAWING: Figure 2
