Title: Control method for wheel with movable means
Inventor: HAYAKAWA KEIZOU
IPC: F03B15/18
Filed: 1980-04-22
Abstract: PURPOSE: To enable a safe termination of a major machine by a method wherein when a guide vane is not operated to close under an emergency stop, this codition is sensed and the runner vanes are fully opened, then the flowing water is shut off by other flow shut-off mechanism.  
     CONSTITUTION: Servo-motor 3 is operated to close under an instruction for closing the guide vanes 2 obtained from a water wheel governor in case of a shut-off of load or an emergency stop of the operation. At this time, a hydraulic pressure found in the servo motor 3 is sensed, and when the pressure is acknowledged as one lower than the predetermined hydraulic pressure, a solenoid for use in opening the runner vanes 4 is operated, and the runner vanes 4 are operated to occupy a maximum angle. Thereby, a centrifugal force acting upon the water wheel and the rotary body directly connected thereto is decreased to about 1/2 of the maximum nonrestricting speed, and at the same time the flowing stream is shut off by other flowing stream shut-off mechanism, thereby the main machine may safely be stopped.

Title: Proportional electromagnetic spool position controller
Inventor: MITO AKIO
IPC: F16K31/06
Filed: 1994-03-24
Abstract: PURPOSE:To displace a spool at an arbitrary stroke other than a natural stroke of a proportional solenoid. CONSTITUTION:When a current is supplied to a proportional solenoid 14, a flapper 16 integrated with a movable iron core 15 is moved leftward against reaction force of a spring 17 to be thus located in a position proportional to thrust force of the proportional solenoid 14 so that a gap Z0 between a nozzle member 8 and the flapper 16 becomes small. Accordingly, a pressure inside an oil chamber 11 is increased, wherein when the pressure exceeds a pressure inside another oil chamber 10, the nozzle member, 8 is moved leftward integrally with a spool 3 with a predetermined gap held between the flapper 16 and the same, and as a result, the input current is proportional to a spool stroke. When a flange 8a of the nozzle member 8 abuts against a stopper 13 so as to lock leftward deviation, the gap between the flapper 16 and the nozzle member is wholly closed so that the pressure inside the oil chamber 11 becomes high, displacing only the spool 3 leftward.

Abstract: PURPOSE:To obtain a speedometer capable of performing measurement under various conditions in a wide measurable range, by utilizing the mutual relation present between a speckle pattern obtained by irradiating an object with laser beam and the moving speed of the object. CONSTITUTION:Coherent beam from a laser diode 10 propagates through an optical fiber 18 and is allowed to irradiate the surface of an object 15 to be measured during movement from the emitting terminal surface of the optical fiber 18 directed to the object 15 to be measured. The diffused reflected beam generated from the surface of the object 15 to be measured forms a speckle pattern and a part of thereof is incident to an optical fiber 19 to be guided to a photodiode 16. The beam intensity distribution of the speckle pattern is converted to an electric signal by the photodiode 16 to be inputted to a signal processing part 17. This signal processing part 17 calculates the self-correlation length of the speckle pattern and calculates the moving speed of the object to be measured on the basis of said self-correlation length.

Title: Turbine blade
Inventor: MANKU HAI TORAN
IPC: F01D5/30
Filed: 1991-02-26
Abstract: PURPOSE: To enhance the performance of a turbine blade and facilitate assembly by positioning the driving center of the root part of each blade in proximity in vertical direction to a plane surrounding the inlet face of a platform part and allowing the thickness of the boundary layer along the convex surface of the blade to remain small. CONSTITUTION: The airfoil part of a turbine blade is composed of a front edge 18, rear edge 20, convex negative pressure surface 22, and concave positive pressure surface 24, wherein the radius of curvature of the convex surface 22 increases at a constant rate from the front edge 18 to the rear edge 20. Thereby the stream decelerates till the neck part of the airfoil, and a constant flow velocity is generated in the region downstream of the neck part. The driving center of the root part is positioned at Point A or in its neighborhood. Point A is positioned in proximity to the plane surrounding the inlet face 26 of the platform part, apart approx. 0.79 inch in X-Y direction away from the inlet face 26, and this distance is substantially identical to the distance between the inlet face 18 of the airfoil and the inlet face 26 of the platform part.

Title: High limit speed pulse doppler measuring apparatus
Inventor: NISHIYAMA HISASHI
IPC: G01F1/66
Filed: 1991-02-26
Abstract: PURPOSE:To maintain an S/N ratio at almost the same value as in the past along with a decrease in erroneous measurement in the direction of blood stream by expanding a limit of a maximum Doppler frequency, measurable without uncertainty, more than several times than that in the past. CONSTITUTION:An average phase difference DELTAthetaG and a phase difference DELTADELTAthetaof the difference are determined from a transmission frequency f0 and a larger transmission frequency f0<1>. Among the results, the phase difference DELTADELTAtheta of the difference is large in error at a low S/N ratio. But, as a rough phase difference is determined, the phase difference DELTADELTAtheta of the difference will not exceed + or -pieven when the phase difference exceeds + or -pi between the respective transmission frequencies and a reception frequency. Thus, +2pi is added to the average phase difference DELTAthetaG using the value to correct the aliasing of the phase difference DELTAthetaG. Moreover, a correction error preventing processing is performed to correct a wrong direction of speed.

Title: Four-wire type resistance measuring apparatus
Inventor: HIRATA KANEMI
IPC: G01R27/02
Filed: 1989-03-07
Abstract: PURPOSE:To prevent misjudgment due to a poor contact of a probe by connecting photodetectors of photocouplers separately between a feeder circuit and a measuring circuit while light emitting elements of the photocouplers connected in series are connected in parallel to a constant current source. CONSTITUTION:Photodetectors 71a and 71b of photocouplers 7a and 7b are connected separately as bypass circuit between a feeder circuit 1 and a measuring circuit 2 connected to the same terminal of a resistance 5 to be measured. Light emitting elements 72a and 72b connected in series are so set that a forward drop voltage rises fairly higher as compared with a potential difference between terminals as given when a normal current flows through the resistance 5 to be measured and connected in parallel to a constant current source 6. Then, when probes 3a, 3b, 4a and 4b are poor in contact, a potential difference between the measuring probes 4a and 4b rises to such a range as to be outputted as information for an excess of a measured value from a differential amplifier 21. As a result, when the four probes 3a, 3b, 4a and 4b does not contact completely, measurement is disabled thereby enabling prevention of misjudgment.
