IPC: G06T7/60
Filed: 1988-02-18
Abstract: PURPOSE:To decide a straight line included only in a necessary window area in a dot sequence picture by deciding the straight line by making theta and rho coordinate value of an obtained cluster into the angle between a perpendicular dropped from the origin of an (x, y) plane to the straight line and an X-axis and the length of the perpendicular respectively.

Title: Cell for particle detector
Inventor: ICHIJO KAZUO
IPC: G01N15/14
Filed: 1990-02-16
Abstract: PURPOSE:To obtain the cell for a particle detector whose detection sensitivity is high by converting an effective irradiation light beam to parallel rays and allowing it to transmit through an internal passage of a cylindrical cell. CONSTITUTION:A laser beam LA21 sent out by a laser 22 is converted to paral lel beam LA22 by a beam expander 23 and irradiates a cylindrical cell 24, and is scattered by particles PIC floating in a fluid 25 which flows through an internal passage 24B of the cell 24. In such a state, a photodetector 27 condenses a scattered beam going to the direction orthogonal to the center beam JA as a detection beam LA23, and obtains a particle detecting signal S21. In this case, an irradiation beam LA22A made by the beam LA22 is refracted by a convex lens effect generated on the external surface of a cell main body 24A and becomes a transmission beam LA22C, and also, refracted by a concave lens effect generated on the internal surface of the cell main body 24A and becomes an effective irradiation beam LA22B, becomes roughly parallel to the center beam JA and passes through the inside of a fluid 25. Accordingly, the irradiation beam LA22A can detect particles PIC with high accuracy even if they are floating in any position in the fluid 25.
