Title: Method and apparatus for fractionating fine particles
Inventor: IMASAKA FUJITARO
IPC: B01J19/12
Filed: 1994-08-01
Abstract: PURPOSE:To simply fractionate many kinds of fine particfles different in particle size or refractive index at the same time with high capacity by irradiating a linear passage filled with a fine particle dispersion with light and accelerating the fine particles along the light irradiation direction by radiation pressure of light. CONSTITUTION:A linear passage 4 moving a fine particle dispersion 3 and light irradiation means 9, 10 for applying radiation pressure of light to the fine particles in the dispersion 3 of the passage 4 are provided. The linear passage 4 filled with the fine particle dispersion 3 is irradiated with laser beam 8 and the fine particles are accelerated along the beam irradiation direction by the radiation pressure of the beam 8 to fractionate the fine particles. As a result, the fine particles receive the action of the radiation pressure of beam, especially, the action of light pressure to be accelerated and fractionated corresponding to the particle size and/or refractive index of the fine particles. A degree of fractionation can be easily adjusted by simple operation changing the intensity of beam.

Abstract: PURPOSE:To utilize luminous flux from a spot light source effectively by providing concave type spherical reflecting mirrors behind and before the spot light source. CONSTITUTION:Luminous flux which is emitted by the spot light source 1 and travels backward is reflected by the spherical reflecting mirror 3 at the back to reach a collimating optical element 6 installed in front of the spot light source 1. Luminous flux emitted forward by the spot light source 1 is reflected by the front spherical reflecting mirrors 4 and 5 and then reflected forward by a diffuse reflecting mirror 2 to reach the collimating optical element 6 through the gap between the reflecting mirrors 4 and 5. The luminous flux reaching the collimating optical element 6 is collimated into parallel luminous flux, which is converged by a linear converging optical element linearly on an original.

Filed: 1980-12-25
Abstract: PURPOSE:To discriminate the presence of print by scanning a print area by an image sensor, by counting the number of bits, which are greater than adjacent bits of an obtained bit by a prescribed value, in the same area, and by finding its ratio. CONSTITUTION:The output of an image sensor 1 is amplified by an amplifier 3 and converted into a digital signal by an A/D converter 4. This signal is set in a register 5 and then transferred to a register 6 by a next CL3. A difference in contents between the registers 5 and 6 is found by an arithmetic device 7 and compared with a prescribed value X by a comparator 8 and when the difference is greater than or equal to the prescribed value X, it is counted by a counter 9. Similarly, the output of the arithmetic device 7 is compared with a prescribed value Y by a comparator 10. This value Y is small and even a small temperature difference is counted by a counter 11. Outputs A and B from the counters 9 and 11 are operated by an arithmetic device 12. A comparator 13 compares the output of the arithmetic device 12 with a prescribed value X and when it is greater than the value X, it is judged that a character is present, preventing double-printing operation.
