Title: Conveying and recovering apparatus for untransferred toners
Inventor: MURAMATSU SHIGERU
IPC: G03G21/10
Filed: 1978-03-03
Abstract: PURPOSE:To provide an untransferred toner conveying and recovering apparatus, which is free from leaving any toner in a conveyor passage, by rotationally driving a conveying member for a preset time period from the start of the cleaning operation of a latent image carrier to the end of the recovering operation of the untransferred toners to a recovery portion. CONSTITUTION:When the operations of an untransferred toner conveying member is stopped at the end of a copying process, the untransferred toners have already been discharged from first and second toner conveying members 3 and 5. A relatively small quantity of the toner is left in a third conveying member 8. The pupose of conveying and recovering the untransferred toners from the member 8 can be sufficiently attained without operating a first conveying member 4 but by operating only a second conveying member 9 for a preset time period after the ocpying process. That preset time period is made slightly longer than the time period for which the toners are completely recovered by the second conveying member 9 at a low speed after the copying process.

IPC: G01N33/49
Filed: 1990-02-02
Abstract: PURPOSE:To make analyses automatically with high efficiency by using two-dimensional smoothing processing for processing of the information on cell light. CONSTITUTION:A sample is sucked by a sample suction tube 4 from a sample container 3 and is sent to a flow cell 10 when a measurement is started. Each one of the cells flowing in one array on the central axis of a flow channel 10a is irradiated with a laser beam l and the intensity of scattering light is measured by photodetectors 15a to 15d. The photodetection signals are sent via a signal processing circuit 20 to a main processor unit MPU 22. The MPU 22 computes the information on the cell light from the output of the circuit 20 by a two-dimensional smoothing method upon ending of the measurement. The adequate autotrigger computation is executed even when the number of data is little or when the extraction of the minimal point is difficult. The automatic measurement with the higher efficiency is thus possible and the higher reliability is obtd.

Subsequently, the plastic spheres 1 are demagnetized and, thereafter, washing water is introduced into the filter cylinder from the bottom openings thereof to be upwardly sent under pressure through the grid 2. Whereupon, the iron component adhered to the plastic spheres 1 is released from each spherical surface and taken out from the top opening of the cylinder along with the washing water.
