Abstract: PURPOSE:To eliminate the necessity for making a conduit the accompanying pressurized conduit for a Pelton turbine and thereby reduce the civil engineering expenses related to the conduit by controlling an needle opening in accordance with water level and deflector openings in line with the number of rotation of the water turbine when the electric power system of the turbine is cut off. CONSTITUTION:To a conduit 31, branch pipes 32, 32a are linked while, at the tip of these branch pipes, nozzles 36, 36a for injecting jet water flows toward the bucket 37a of a Pelton turbine 37 are formed. The quantity and direction of water flows from the nozzles are controlled through a needle 33 and deflector 38, 38a, with the number of rotation of the water turbine being controlled accordingly. Since a needle opening controlled in accordance with water level in a head tank, and deflector openings are adjusted with to the number of rotation of the water turbine when the electric power system is cut off, it is possible to wait for the restoration of the system while continuing discharge operation. And since no pressure increase occurs in the conduit, it structure can be simplified.

Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To surely detect an optical flow on a boundary of an object in an optical flow detection which uses a gradient method. SOLUTION: A picture obtained by a CCD camera 10 is given to a picture processor 12. A processing part 16 of the picture processor 12 detects a temporary optical flow provisionally under a fixed condition by using the gradient method. The spatial gradient of the detected temporary optical flow is calculated and a diffusion coefficient α is decided so as to have a negative correlation with the spatial gradient. By using the diffusion coefficient αwhich varies with the spatial gradient, an optical flow component by the gradient method is extracted by adding the condition which minimizes the spatial change of the optical flow. By making the diffusion coefficient α variable, the optical flow which is resistive to noise and has emphasized difference at the boundary of the object is obtained.

Filed: 1995-02-06
Abstract: PURPOSE: To precisely perform an engine control by switching voltage of an AC power source for supplying an image recording operation power based on the control signal from the engine controller. CONSTITUTION: The voltage switching means of the AC power source 1 for supplying the image recording operation power is constituted of a transistor 32 and a resistor 33. When a printer begins the printing operation from a standby state, a print signal turned to high output by an engine controller 22, the value of 5V voltage divided by the resistors 25, 26 and 33 is raised by turning on the transistor 32, and a current flowing from the cathode of a shunt regulator 24 to the anode is reduced.

At this time, the engine controller 22 corrects errors by lowering an A/D conversion value by a raised portion of the output voltage of the engine control power source.
