Title: Photoreceptor exposure adjusting method in copying machine
Inventor: OGURA YUKIO
IPC: G03G15/04
Filed: 1978-04-06
Abstract: PURPOSE: To realize elimination of exposure unevenness regardless of reciprocity law of photoreceptor, by changing the quantity of emission of illumination lamp of illumination optical system depending on the changes in the incident angle of the exposure luminous flux into the imaging lens system.  
     CONSTITUTION: In the event of slit exposure, since the incident angle θ of the exposure luminous flux into an imaging lens system 2 varies continuously during exposure, the vignetting factor differs according to th cosine fourth power law. As the incident angle θ becomes larger, the image plane illumination of optical image at exposure position P lowers. With the image plane illumination at incident angle θ=O taken as 100%, in order to image at the exposure position P at image plane illumination 100% when θ is not O, that is, to achieve slit exposure under the same condition, it is enough to change the quantity of emission of the illumination lamp in a way that the illumination of the slit-form lighting part may change as shown in the drawing according to the variation of the incident angle θ. In paractice, by changing the applied voltage to the illumination lamps 42, 52 depending on the incident angle θ, exposure may be performed always under the same conditions, so that unevenness of exposure may be eliminated.

Abstract: PURPOSE: To effect highly efficient and economic deairization (abstracting air) of feed water by spouting preheated feed water from a nozzle, constructed so as to produce air bubbles, into a deairizing chamber in which inside pressure is below a saturated pressure against a temperature of the feed water.  
     CONSTITUTION: Feed water, coming from a conduit 101 communicating with a condenser 70 for a steam turbine 60 and a conduit 106 for suplemental feed water, is heated in a low-pressure feed water heater 80 and a heat exchanger 10, subsequently, is spouted through a feed water nozzle 30 into a deairizing chamber 20 in which inside pressure is below a saturated pressure against a temperature of the feed water in a conduit 103. In this case, the inner portion of the nozzle 30 is constructed such that sudden decrease of pressure is caused locally in the nozzle 3 due to a variation of sectional area of the fluid and air bubbles are induced in that portion. Therefore, mixed stream of the air bubbles and the feed water flows in the feed water nozzle 30 and is spouted from the tip of the nozzle. Accordingly, stream of vapor accompanied with abstracted air is separated from the feed water due to effects of difusion of gas into air bubbles and stiring of the feed water by the bubbles.
