IPC: G03G15/01
Filed: 1984-05-29
Abstract: PURPOSE:To decrease the number of processes and to obtain a sharp color image having high purity and high resolution with one process by exposing a color-separated picture signal with a light beam to form an electrostatic latent image, developing said image in reversal by the coloring toner of the color thereof and repeating such operation with the other image signals to form the plural color toner images on a photosensitive body. CONSTITUTION:The surface of the photosensitive body 1 under rotation is uniformly and positively electrified by a corona electrifier 2. The black picture signal decomposed to a picture element is scanned and exposed by a laser oscillator 3. The resulting electrostatic latent image is subjected to negative-positive reversal development with a black toner by a developing device 7. The yellow image signal is then scanned and exposed in the Y, G, R part by a laser oscillator 4. The spot diameter in the part Y is made smaller than the spot diameter in the other parts. The yellow electrostatic latent image is subjected to reversal development with the yellow toner by a developing device 8. The magenta picture signal is scanned and exposed in the M, B, R part by a laser oscillator 5 and is subjected to the reversal development with the magenta toner by the device 8. The similar operation is made with the cyan image by using a laser oscillator 6 and a developing device 10 and the images are electrostatically transferred by the corona electrostatic charger 11.

IPC: B22D43/00
Filed: 1988-05-02
Abstract: PURPOSE: To effectively separate inclusion contained in molten metal to a low level with a filtration by acting electromagnetic force to a filter medium passing through molten metal.  
     CONSTITUTION: The molten metal is passed through in the filter medium 1 in the arrow mark 2 direction and filtered to separate the inclusion in the molten metal. In the separating method of the inclusion, DC current is supplied into the filter medium 1 in the arrow mark 3 direction parallel with the filtration direction 2. Magnetic field in the arrow mark 4 and the electromagnetic field 5 toward the center are generated with this DC current itself. The value of this electromagnetic force is suitable to be 1×10 3 -1×10 6 N/m 3 . By this method, the shifting of the molten metal in the direction 2 into the filter medium 1 is promoted and also, the inclusion is shifted to the reverse direction of the electromagnetic field with this reaction. Therefore, e.g. the filter medium 1 is constituted with porous body having larger hole in the cross section than the inclusion, and the molten metal is passed through the porous body at 0.1-1.5 cm/sec speed and the inclusion can effectively be separated.
