Title: Condensation heat transfer pipe
Inventor: HIRASAWA SHIGEKI
IPC: F28B1/00
Filed: 1981-02-06
Abstract: PURPOSE:To raise the heat transfer efficiency of a condensation heat transfer pipe, by forming sections, for rejecting sticking of condensed liquid over the inner wall surface of a heat transfer pipe with appropriate intervals from each other. CONSTITUTION:When steam is introduced into a heat transfer pipe 1, it is sticked and condensed on the surface of small inner wall sections 1Aa. Liquid film formed through condensation of steam is made to flow axially of the pipe 1 by the function of shearing force of steam flow and reaches sections 2 which reject sticking of condensed liquid. However, liquid film is not form over the surface of these sections 2, so that a portion of liquid film is blown away from the surface by steam flow and forms liquid drips, which are carried toward a downstream portion by the steam flow. Thus, since liquid film sticked to the surface of small inner wall sections 1Aa is removed at adjacent sections 2 rejecting sticking of condensed liquid, steam is always cooled and condensed efficiently through contact with heat transfer surfaces effective for condensation, i.e., small inner wall sections 1Aa.

Title: Treatment of waste gas
Inventor: YOSHIOKA TATSUYA
IPC: B03C3/40
Filed: 1982-02-03
Abstract: PURPOSE:To improve dust collecting efficiency as well as to prevent white smoking from a chimney and to improve a diffusion effect in the stage of treating waste gas with a wet type desulfurizer through an electrical dust precipitator by conducting the waste gas from the desulfurizer into the hollow dust precipitating electrodes in the dust precipitator. CONSTITUTION:For example, the waste gas of a coal boiler is cooled with an air heater 1 and is introduced into an electrical dust precipitator 2 consist of hollow dust precipitating electrodes 3 of pipe or square shape. However, in this state, the dust of high resistant sticks on the electrodes 3, and causes back corona phenomena, by which dust precipitating efficiency is decreased. Thereupon, the waste gas passes through the precipitator 2 and since the waste gas flowing out from a wet type desulfurizer 4 is low in temp., the waste gas is conducted to the electrodes 3 to cool the electrodes 3, whereby the temp. of the high resistance dust stuck thereon is reduced and the electric resistance value is decreased. Thus, back corona phenomena are prevented and dust precipitating efficiency is improved. On the other hand, the waste gas past the electrodes 3 is heated, whereby the white smoking of the gas released from a chimney 5 is prevented and a diffusion efficiency is improved.

Abstract: PURPOSE:To prevent a malfunction caused by dust, etc., by adding a cleaning member to clean the light flux incident surface of an in-focus detecting photoelectric conversion element in coupling to an opening/closing action of the camera back over. CONSTITUTION:A cleaning member 13 rocks around a rotary shaft 13a by the rocking action of a coupling cam 11. A rotary cam 9 is provided at the tip of the cam 11 and energized counterclockwise by a spring 17 to be rolled up by a tooth for every roll-up action via a driving gear 15. In such constitution, a relation between a lever 16 that prescribes the position of the gear 15 and a spring 18 is cut off by opening a back cover 19. Then the cam 11 is turned left by a spring 14 to go into the cam 9. On the other hand, the cam 9 is turned left due to the cutoff of the relation with the gear 15. Thus a cam 11b engages a pin 9a to give a reciprocal movement to the member 13 via the lever 11. As a result, an optical member 8 is cleaned every time the cover 19 is opened and closed to prevent a malfunction caused by dust, etc.
