Title: Continuous production of bleaching liquid
Inventor: KOSHI MINEICHI
IPC: C01B11/06
Filed: 1984-07-13
Abstract: PURPOSE:To produce bleaching liquid continuously and stably, in high efficiency, by dividing the reaction zones in the production process into two stages, introducing chlorine gas dividedly to each stage, and reacting milk of lime with chlorine gas in the zones under the optimum absorption and reaction conditions. CONSTITUTION:A bleaching liquid composed of calcium hypochlorite as a main component is produced from milk of lime and chlorine gas. In the above process, the reaction zone is divided into two stages, and chlorine gas is introduced dividedly into each stage. The effective chlorine concentrations in the reaction solution in the first reaction tank 1 and the second reaction tank 2 constituting the first-stage reaction zone are controlled constantly to 40-100g/l by adjusting the feed of the lime milk and chlorine gas, and the effective chlorine concentration in the third reaction tank 3 constituting the second-stage reaction zone is maintained at a specific level to effect the completion of the reaction and obtain the objective bleaching liquid. The concentration is preferably detected with ORPE3, and the flow of a small amount of the chlorine gas is controlled with the automatic valve V4.

Filed: 1988-06-10
Abstract: PURPOSE:To improve the utilization efficiency of light and facilitate optical axis alignment by forming light waveguide layers which vary in equivalent refractive index in the traveling direction of the light on both surfaces of a substrate which transmits light. CONSTITUTION:The waveguide layers 2 and 4 which vary in equivalent refractive index in the traveling direction of the light are formed on both sides of the substrate 3 which has light transmissivity. The 1st optical waveguide layer 2 and 2nd optical waveguide layer 4 decrease in thickness in a tapered shape toward a substrate end part 3a and called a 1st tapered coupler 2a and a 2nd tapered coupler 4a. The light is guided into the 1st optical waveguide layer 2 and propagated in the layer, but when it is propagated to the 1st tapered coupler 2a, it is emitted gradually to the side of the substrate 3 and emitted out of the substrate end part 3a. The light which enters the 2nd tapered coupler 4a from the substrate end part 3a is converted to the waveguide mode of propagation in the 2nd optical waveguide layer 4. Consequently, a high-efficiency input/output coupler is realized and the optical axis alignment is facilitated.

Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To efficiently from front and back images onto an image carrier and to transfer them to the front and back of a transfer material at the same time by allowing image formation on a toner-image receiving body to precede image formation on the photosensitive drum used for transfer to the front of the transfer material, by synchronization with the reading of an original document. SOLUTION: In a transfer area 14b, superimposed color-toner images as a back image on the photoreceptor drum 10 are transferred all at once onto the toner-image receiving body 14a, provided close to the photoreceptor drum 10, by means of a transfer unit 14c to which a voltage having the opposite polarity of toner is applied. In synchronization, in the transfer area 14b, with the back image formed on the toner-image receiving body 14a, the front image as superimposed color-toner images is formed onto the photoreceptor drum 10. Thus, because, the superimposed color-toner images are transferred all at once, color slippage of the toner images on the toner-image receiving body 14a, toner scatter and rub, etc., hardly occur, and satisfactory both-sided color- image-formation with less image-deterioration is performed.
