摘要： It is used a filter trapping particulates from a gas containing the particulates, a container 5 containing the filter, an upstream pipe 3 provided on the upstream side of the container 5 to lead the gas "A" into the container 5, a downstream pipe 4 provided on the downstream side of the container 5 to lead the gas "B" after the gas passed through the filter, a transmitting antenna 11 to transmit an electromagnetic wave having a frequency of 80 GHz or more and 200 GHz or less, and a receiving antenna 10 to receive the electromagnetic wave. An amount of the particulates trapped in the filter is detected based on an intensity of the electromagnetic wave received by the receiving antenna 10.

摘要： It is provided a radio oscillating system for oscillating a radio signal. The system has an optical modulator for oscillation, a modulating means for inputting a modulating signal of a frequency of fm into the optical modulator to modulate a carrier wave so as to interpose sideband waves onto the carrier wave at positions shifted with respect to the frequency of the carrier wave by the frequency "fm"; and an optical receiver for oscillation for receiving beam from the optical modulator and converting the beam into an electrical signal. The system further has a radiating means for radiating radio signal of a frequency of 2fm based on the electrical signal. An input voltage Vp-p applied on the optical modulator is 1.0 times or more and 1.99 times or less of a half-wavelength voltage Vπ of the optical modulator.
