Title: Partial measuring type fine particle counter
Inventor: SUZUKI RIICHIRO
IPC: G01N15/02
Filed: 1988-07-30
Abstract: PURPOSE:To prevent the effects of aberration and defocusing and to improve resolution and S/N by correcting the distribution of the integral value of light intensities in the direction perpendicular to the flowing direction of a fluid to be measured and the projecting direction of a laser beam in a square shape. CONSTITUTION:The distribution of the flow speed of a fluid to be measured S which is flowed from a nozzle 1 at a specified flow speed in a flow cell becomes uniform as much as possible in a detecting region R at the central part. A laser beam L is projected from the side in the direction (y) which is perpendicular to the flowing direction (z) of the fluid S in an optical projecting system A. The beam is made flat through a cylindrical lens 2. The distribution of the integral value of the light intensities in the direction (x) is made square with a light intensity correcting means 6. Scattering light L' of the beam L due to fine particles in the fluid S is detected in an optical detecting system B from the side of the direction (x). The image of the light is formed at a wide slit 4 which is provided in a slit member 5 by way of light receiving lenses 3 and 3. Sufficient allowance is provided in the direction z' which is perpendicular to the position where the image is formed. The direction (y) is limited, but the direction z' is not limited.

Title: Symbol recognition system
Inventor: INOUE AKIRA
IPC: G06K9/62
Filed: 1985-08-30
Abstract: PURPOSE:To improve the efficiency of symbol recognition by expressing an angle element included in the characteristics of a segment in the relative quantity. CONSTITUTION:Each segment composing a symbol is extracted by an extracting means. A standard segment is selected by a standard segment selecting means 2 corresponding to each extracted linear segment. This standard segment is used in a converting means 3, and each extracted segment is converted into a segment where the selected standard segment is used as a reference. In such a way the segment is converted into a segment having no angle as a factor for the symbol recognition. Thereby the inclination of the symbol never affects the symbol recognition.
