Title: Method and apparatus for separation of particle
Inventor: IMASAKA FUJITARO
IPC: B01J19/12
Filed: 1993-07-08
Abstract: PURPOSE:To carry out the particle separation and classification easily and surely by basically irradiating scanning light to a plurality of areas of a nonlinear flow route in which moving particles such as biologic related particles of cells, industrial particles, etc., flow and thus applying a functional force according to the types of the particles. CONSTITUTION:A nonlinear flow route 2 which is curved a plurality of times is formed in the inside of a flow cell 1 and a dispersing medium in which a plurality of types of particles exist is made to flow in the route. Scanning light is so irradiated to the nonlinear flow route 2 as to make the scanning track 3 transversely cross the flow direction of the dispersing medium. Light is thus irradiated to a plurality of areas along the flowing direction of the flow route 2 and particles moving based on light gradient force receive braking force in the light irradiated areas. At that time, larger braking force works on particles with larger size or refractive index rather than on particles with smaller size or refractive index. As a result, smaller particles on which smaller braking force works pass the light irradiating positions quickly and thus the particles are classified successively from smaller particles with smaller braking force to larger ones. Consequently, the separation and classification of the particles are carried out easily and surely.

Abstract: PURPOSE:To enable continuous minute flow switching control and temperature control by fitting a one-way shape memorizing alloy spring and a normal spring in opposition to the generated force of the alloy spring in the fluid passage of a main body and connecting both springs by a switching valve for moving these springs in the direction of generated force. CONSTITUTION:The pressing face, facing the partition 1c of a main body, of the valve head part 13b of a switching valve body 13 in a normal spring storage part 16 is in contact with a wall surface 15b when a spring 12 is extended, and the ouflow of a fluid to the high temperature outflow passage 4 side is stopped. At this time, the valve head part connecting part 13c of the valve body 13 is shifted to the left so as to contract a shape memorizing alloy spring 11, and the valve head part 13a is separated from a wall surface 15a so as to open the exit of a low temperature outflow passage 3, thus enabling the fluid to flow out to the outflow passage 3. When the temperature of the fluid rises to the high temperature side, and the spring 11 has an austenite phase, the spring 11 is reset to the memorized shape, and the valve body 13 is shifted to the right pushing the spring 12. The valve head part 13a therefore reaches the wall surface 15a, so that the flank of the valve head part 13a closes the exit of the outflow passage 3, and the valve head part 13b is separated from the wall surface 15b, thus enabling the fluid to flow out to the outflow passage 4 side.

Filed: 1984-08-14
Abstract: PURPOSE:To provide multiple outputs stable to a fluctuated load by generating power different from that of the first high voltage power generator receiving two levels of predetermined voltage not corona dischargeable between predetermined electrodes and predetermined voltage corona dischargeable. CONSTITUTION:Upon receiving a signal SG1 synchronized with the timing of a copying machine for applying development bias, output terminal OUT1 is applied with voltage of 1-2kV and output terminal OUT2 is applied with voltage of 200V generated from voltage of 1-2kV. In such a case, the potential at output terminal OUT1 is not corona dischargeable. Upon receiving a signal SG2 synchro nized with the transcription, output terminal OUT1 is applied with potential of several kV to enable corona discharge, while the voltage at output terminal OUT2 is maintained at 200V by means of ZNR. When applied with development bias, no corona discharge occurs to reduce the load of power source but the voltage at the primary side of transformer T is low so that the operation of power source is stabilized.
