Title: Carburetor
Inventor: UEDAHIRA KUNISUKE
IPC: F02M19/03
Filed: 1978-05-24
Abstract: PURPOSE: To enhance an atomization of fuel injected from a nozzle, by locating a main nozzle of a carburetor in such a direction that cuts a small venturi at right angles, and by forming its opening in a streamline shape.  
     CONSTITUTION: A carburetor consists of a small venturi 2a and a large venturi 8. A main nozzle 3, which connects with a fuel passage 7 having a main jet and an air breed 5, is located at a narrowest part of the small venturi 2a and in the direction that cuts the small venturi at right angles, and the opening of the main nozzle 3 is formed in a streamline shape against a suction flow. This causes a fuel to be blown off by the suction flow and thus an improved atomization can be performed.

Abstract: PURPOSE:To enable formation of a developed image having high quality with good reproducibility by using a developer, developer carrying body and developer coating blade in such a way that the coefft. of internal friction resistance and coefft. of kinetic friction of the developer maintain specific conditions. CONSTITUTION:A toner conveyed according to rotation of a developing roll 21 approaches the electrostatic latent image on a photosensitive drum 33 and scatters by Coulomb force in the space between the roll 21 and the drum 33, thus forming a developed image. A toner 29, the roll 21 and an elastic blade 23 are so used as to attain mui<mur and mui<mub when the coefft. of internal friction in the toner 29 is designated as mui, the coefft. of kinetic friction between the peripheral surface of the roll 21 and the toner 29 as mur and the coefft. of kinetic friction between the surface of the blade 23 and the toner 29 as mub. The uniform toner layer having an extremely thin thickness is thus formed on the peripheral surface of the roll 21, by which uniform and substantial electric charge is applied to the toner particles and satisfactory development is executed.

A target value ao of residual chlorine is usually in the range of 1-2ppm and it is successively obtained by a calculator 34 from A=C1C4d+C2a2T+ao+C3, using the chlorine demand in a water purifying plant. Through said procedure, the previous demand value of chlorine is unambiguously determined wherein seasonal correction is unnecessitated.

Title: Combustion apparatus
Inventor: ISOZAKI TAKESHI
IPC: F23N5/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a combustion apparatus which, when the combustion capacity is lowered considerably, enables avoiding degeneration of the condition of combustion caused by lack of air. SOLUTION: While fan revolution-controlling data R, S, T, U comprised of a plurality of steps each differing from the others in number of revolutions relative to the combustion capacity are preliminarily given, there is provided a fan revolution control part for lowering shift of capacity. The fan revolution control part for lowering shift of capacity monitors variation in combustion capacity and, when the combustion capacity has decreased in excess of a preliminarily set capacity-lowering variation, the revolution of the combustion fan is controlled by a shift from the fan revolution controlling data before the lowering shift of capacity to the fan revolution-controlling data in an upper step.  When there is possibility that the lowering shift of the combustion capacity may cause the air volume supplied to the combustion to decrease below the volume of air adequate for satisfactory combustion, by switching to the fan revolution control data in the upper step it becomes possible to supply air at a volume adequate for satisfactory combustion so that degeneration of the condition of combustion caused by lack of air or going out of a flame can be prevented.

Abstract: PURPOSE:To eliminate a special lever or mechanism for drawing out paper which is jammed, by interrupting a driving device for carrying a recording form from a driving source by making a unit containing an image forming photosensitive body escape from a copying body. CONSTITUTION:At the time of replacing a unit U forming a photosensitive drum 7 and its peripheral part to a unit, its unit U is removed from a copying machine body, but in this case, the gear 31 of the photosensitive drum 7 is also removed integrally with the unit U. Accordingly, in case of a state that the unit U is removed in this way, a gear train extending from the next gear 32 of its gear 31 to the last gear 40 is released against a gear train extending from the output gear 27 of a motor 26 to a gear 30, and can rotate freely. In this way, when a paper jam is generated in a fixing roller 16, its fixing roller 16 can rotate easily by removing the unit U, therefore, paper which is jammed can be removed by only drawing it.

Abstract: PURPOSE:To prevent adverse influence on an image due to a synchronizing signal generating optical beam, by making scan an area except the latent image forming area of a photosensitive body, accompanied by the rotation of a rotary polygon mirror. CONSTITUTION:The laser beam printer is constituted so that a synchronizing signal generating laser beam B' is made incident on the reflecting plane 3a of a polygon mirror 3 diagonally from the upper side against a flat plane on which an image forming laser beam B is scanned, and after that, it is reflected diagonally to the lower side, and is made advance toward a synchronization control light receiving part 8. In other words, it is constituted so that, even when the synchronizing signal generating laser beam B' is scanned accompanied by the rotation of the polygon mirror 3, the synchronizing signal generating laser beam B' is prevented from arriving at the latent image forming area S of a photosensitive drum 4. In this way, no latent image which becomes the noise for a bit of picture information, is formed on the photosensitive drum 4, and deterioration in the image can be evaded.
