At the time when the voltage VCS1 of the capacitor CS1 is equal to the voltage VCO of the capacitor CS2, diodes DS21 DS22 are conducted and electric current iCS2 flows through the snubber circuit 100. Further, the electric current iCS1 of the snubber circuit 200 decreases gradually. The R-phase current iR of an AC power supply 1 is reduced to zero while the S-phase current iS increases so that commutation is completed.

Title: Measurement of particle intermixing condition
Inventor: TAGASHIRA KENJI
IPC: G01N21/49
Filed: 1983-06-10
Abstract: PURPOSE:To successively measure intermixing conditions of particles without exerting any influence on the intermixture of particles by employing main particles and tracer particles which respectively have a different rate of light beam reflection and measur ing the intensity of the reflected light from a particle layer. CONSTITUTION:Main particles M and tracer particles T, which respectively have a different rate of light beam reflection, constitute a partcle layer A and make a motion constantly. On the other hand, the laser beam generated in a laser source 1 is transmitted by means of a light-combined optical fiber 2 for transmitting light, with which laser light the inside of the particle layer A is irradiated. The laser light is reflected by the main particles M or tracer particles T and enters an optical fiber 3 for receiving light. The voltage, which comes from a photoelectric converter 4, corresponding to the intensity of the reflected light, is recorded by means of a recorder 6 through an amplifier 5. With this process, a light L reflected by the main particles M having a low rate of light beam reflection is not obtained immediately after the tracer particles T have been introduced. According as two kinds of particles are gradually intermixed, however, the intensively reflected light given by the tracer particles T enters. The period of high voltage is recorded at substantially equal intervals in an evenly intermixed state of particles.
