Title: Method and apparatus for measuring particle characteristic by modulated light scattering method
Inventor: DARERU KEISU HATSUCHINSU
IPC: G01N15/02
Filed: 1989-09-14
Abstract: PURPOSE: To lift general basic limitations by measuring the the characteristics of particle using modulated dynamic light scattering method(MDLS) for determining the mass of each particle by measuring mean square movement of each particle in X direction. CONSTITUTION: The inventive system employs MDLS method where a measurement σ<2> of mean square movement is equalized to a theoretical value determined according to an expression and the mass of each particle is determined from a value optimal the number of each conditions of each particle determined by a requirement m=kTt<2> /σ<2> or each measurement of σ<2> . A light beam A passes through a concentration filter 14 and the illuminance is attenuated before being split through a beam splitter 16 into beams 1, 2. The beam 1 further passes through an acoustooptical modulator 20 and the frequency is shifted by F0 . The beam 2 also passes through an acoustooptical modulator 21 and the frequency is shifted by F0 +▵F (normally, |▵F|>=1kHz) before reflected 22. Consequently, the beam 2 is passed through a lens 23 and a polarizer 24 and then deflected by a reflector 26 thus improving the purity of a single beam component.

Filed: 1991-09-19
Abstract: PURPOSE:To burn off the dust adhered to a heat generating resistance body of a heat generating resistance type air flow sensor well, thereby to enhance the detecting accuracy of the sucking amount of air and to elongate the life of the heat generating resistance body. CONSTITUTION:The dust adhered to a heat generating resistance body is mainly composed of oil in summer or sand in winter because of the dry air. The oil can be burnt off by heating the same to a boiling point. The sand is necessary to be red-hot to 1000 deg.C. The amount of the dust adhered to the heat generating resistance body is dependent on the running distance since the dust was burnt off last time. The particle size of the dust is detected from the pressure of an air filter in the succeeding stage. Therefore, a plurality of combinations of the conductive pattern to a hot wire and the changing pattern of the air flow directed to the heat generating resistance body at the heating time are prepared beforehand. One of the combinations is selected in accordance with each detecting value of the temperature of the cooling water of the engine, the running distance, the pressure of the air filter in the succeeding stage. The heat generating resistance body is heated according to the selected pattern to burn off the dust. The air flow is applied to blow the dust off.
