Title: Preventor against involvement of air bubble
Inventor: KYOGOKU TAKEJI
IPC: E02B7/16
Filed: 1985-12-17
Abstract: PURPOSE:To prevent the involvement of air bubbles and also the formation of swirls by a method in which the upper end of a cover provided above a dam is positioned on the water surface of upstream, and the length of the lower end of the cover is regulated to one enough to submerge under the water surface of downstream. CONSTITUTION:In allowing water to overflow a dam 3, the position of a cover 1 is adjusted according to the level of water by using a wire 2. The upper end 11 of the cover 1 is set on a level equal to the water surface 8 of upstream, and the lower end 12 of the cover 1 is controlled to a length enough to submerge under the water surface 9 of downstream (sea level). Since the upper end 11 of the cover 1 is always on the position of fixed stream, the involvement of air and formation of swirls can be prevented. Also, since the lower end 12 of the cover 1 is submerged under water surface, the rush of falling water into sea surface 9 can be prevented and the involvement of air can also be avoided.

Abstract: PURPOSE:To attempt the improvement of durability, reliability, stability and facilitation, relative to the lighting circuits in the title, by controlling a switching element in accordance with voltage in a feedback winding through a control circuit, and then keeping the output of a self-excited type inverter circuit constant and at the same time making a light adjustment through a light adjuster circuit. CONSTITUTION:When voltage in a feedback winding 11 ries with the large output of a self-excited type inverter circuit 3, a control circuit 21 controls a transistor 5 to lower the output of the self-excited type inverter circuit 3. When voltage in the feedback winding 11 also falls with the small output of the self-excited type inverter circuit 3, the control circuit 21 controls the transistor 5 to heighten the output of the self-excited inverter circuit 3. When a light adjuster circuit 20 is opened, then the self-excited inverter circuit 3 gives the entire light output thereof for putting the entire light to an electric discharge lamp 16. When the light adjuster circuit 20 is closed, part of the base current flowing through the transistor 5 is bypassed to lower the output of the transistor 5, with lowering the output of the self-excited type inverter circuit 3 to put a dimmed light to the electric discharge lamp 16. This makes it possible to attempt the improvement of durability, reliability, stability and facilitation, relative to the lighting circuits in the title.
