Title: Tap switching controller
Inventor: YOSHIDA KATSUYA
IPC: H05H1/22
Filed: 1980-11-28
Abstract: PURPOSE:To increase the lifetime of a tap switching controller, by applying the voltage reference value to both a tap switching device and a voltage controller from a setter and accordingly not only simplifying the control of the setter but reducing the fluctuation of the output voltage. CONSTITUTION:A tap switching controller controls consecutively the output voltage in a wide range through both the rough control carried out by switching the tap of a transformer 1 and the fine control by a voltage controller 4 such as a regulator tube, etc. Then a consecutive reference is applied from a setter 5 to tap switching devices 6 and 7 plus the controller 4 of such tap switching controller. The output voltage V and the voltage reference V0 are comparated with each other through a consective control part 8 to give the control to the controller 4. At the same time, the reference V0 is compared with the voltage corresponding to the tap position of the transformer 1 through an on/off control part 6. And when this deviation becomes larger than a prescribed level, the tap switching is successively carried out.

Title: Stirring device for water tank
Inventor: SHIMURA MASUO
IPC: B01F7/24
Filed: 1979-12-24
Abstract: PURPOSE:To flocculate impurities through agitating the water added with a slight amount of a flocculant by revolving a rotary vane with a rotary vane driving device provided on the bottom surface of a water tank, leading water flow through the suction port at the upper part, and releasing the same from the lower part of a water passage. CONSTITUTION:When a rotary vane driving device 6 is driven, a rotating shaft 8 and a rotary vane 7 rotate rapidly, and draw the water flow from above to a downward direction then release the same, hence the water near the water surface is drawn through a suction port 12 into the swirling motion of the vane 7 via a water passage 13, after which it is released to four circumferential directions. The water flowing into the suction port 12 is mostly the flow 18 sucked up from the water below the end of a water leading disc 11. Hence, when a small water tank of several m<3> capacity is used, released flow 17 strikes against the side wall of the water tank, ascends and circulates; so, the surface flow is also generated, by which agitating effect is produced. Hence, when a slight amount of a flocculant is added, impurity components are flocculated and floated or flocculated and sunk by the agitation effect, whereby the water is clarified.

Filed: 1987-07-03
Abstract: PURPOSE:To execute an exposure control with high accuracy by adjusting a light emission luminance of a CRT so that an exposure time goes to an integer multiple of a raster period at the time of printing a photographic image. CONSTITUTION:When a color negative film 12 to be printed is set to a negative carrier 11 and a power source is turned on, a CRT 10 emits a light beam by a reference luminance and illuminates the color negative film 12. A part of the light beam which transmitted through this color negative film 12 is made incident on photoelectric parts 30-32 and brought to a photoelectric conversion. Output signals of these photometric parts 30-32 are brought to a digital conversion by an A/D converter 33, and thereafter, inputted to a controller 34, and converted to a density signal therein. The controller 34 derives an exposure time Ti by using an average transmission density, calculates the number of frames Ni and a luminance correction value li, so that said exposure time Ti goes to an integer multiple of a raster period (t), and corrects the exposure time to an integer multiple of the raster period by increasing or decreasing the light emission luminance of the CRT. In such a way, the exposure quantity can be controlled with high accuracy.

Filed: 1986-07-16
Abstract: PURPOSE:To record a picture having a good picture quality while recording on a film is made into a sampling recording by emitting intermittently a beam modulated in accordance with a video signal. CONSTITUTION:A video signal VID is given to a driving circuit 4, amplified by an amplifying circuit 5 and given to an adding circuit 6.
