Title: Flowmeter
Inventor: SHIMADO SHOJI
IPC: G01F1/10
Filed: 1991-03-28
Abstract: PURPOSE:To enable highly-precise and stable measurement of a flow rate of a fluid by forming a truncated-cone-shaped peripheral surface on the end part of a rotating shaft of an impeller, by forming a cone-shaped peripheral surface on a bearing member and by forming dynamic pressure grooves in one of the peripheral surfaces opposed to each other. CONSTITUTION:A rotating shaft 6 is fixed in the center of an impeller 5 and the end parts of the rotating shaft 6 are supported rotatably by bearing members 7 and 8. Besides, a truncated-cone-shaped peripheral surface 12 is formed on the end part on the outlet side of the rotating shaft 6 and herringbone-shaped dynamic pressure grooves 13 are formed in the peripheral surface 12. Moreover, a recessed part is provided in the member 8 so that it is opposed to the peripheral surface 12 and a cone-shaped peripheral surface 14 is formed inside the recessed part. When a fluid flows in from the inlet side, the rotating shaft 6 is pressed against the member 8 by the pressure of the fluid applied to a vane 5a and the impeller 5 is started to move. Since the area of contact of the rotating shaft 6 with the member 8 is small in this construction, a frictional resistance is small and thus responsiveness of rotation to a change in a flow rate and precision in measurement can be improved.

Filed: 1978-06-01
Abstract: PURPOSE: To prevent burning of primary winding due to the rapid increase of exciting current by setting the magnetic flux density of the iron core of gas PT below 1/2 of the saturated magnetic flux density at a rated voltage.  
     CONSTITUTION: The magnetic flux density of the iron core of gas PT is set below 1/2 (10T) of the saturated magnetic flux density at a rated voltage. By this, even if a voltage nearly twice as large as the rated voltage for gas PT is impressed, in operating a on-the-site withstand AC voltage test on a gas-insulating, sealed type switchegear of a non-effective ground system, since the magnetic flux density of the iron core of gas PT is below the saturated magnetic flux density (20T), no burning occurs to primary winding that might be caused by the rapid increase of the exciting current due to the saturation of the iron core.

Title: Thrust force generating method and apparatus as its application
Inventor: KINOSHITA KIYONOBU
IPC: F03G7/00
Filed: 1995-02-15
Abstract: PURPOSE: To generate a thrust force for a vacuum space without requiring use of any fuel by placing an object having a certain mass in a field of force such as an electrostatic field, static magnetic field, or a field of centrifugal force, and allowing the object to make reciprocative motions parallel with the force given by the field of force. CONSTITUTION: A vibrational thrust force proportional to the square root of the product of the force, deflection width, and mass and also proportional to the vibrating frequency is generated only with continuance of the vibration in the direction of the force given by a field of force. The end face consisting of the plane of an oscillator 1 is magnetized in parallel striation so that the oscillator 1 itself has a vibration maintaining ability and holds a certain amplitude, and the surface of a permanent magnet 4 facing that end face is alike magnetized in striation. These are positioned opposingly in such a way that they intersect each other, and a repulsive force is generated. A plate 5 of an electric conductive material is interposed in between so that the varying velocity of the magnetic field is retarded, and an energy to promote vibration is generated.  The thrust force produced in the oscillator 1 is transmitted to a coupling 2 which couples it with the permanent magnet 4, and thereby the object as target is propelled.

Title: Intermittent power transmission mechanism
Inventor: HASHIMOTO TATSUTOSHI
IPC: F16D71/00
Filed: 1982-04-20
Abstract: PURPOSE:To selectively transmit power at extremely accurate timing by constantly causing an output shaft to stop at a certain rotationary position determined at a timing of a lobe in a dent when a power supply is cut off. CONSTITUTION:When a main switch is off, a solenoid 52 becomes inoperative and a return spring 51 forces a control member 49 to turn in the direction B. A lobe 46 then comes into contact with the circumferential face of a control cam 37 while a pawl 48 comes out of engagement with a ratchet wheel 43. A clutch mechanism 44 therefore comes in engaged position. If a power supply is cut off, a motor of a driving system of an input shaft 41 is, as inevitable consequence, halted, however, the input shaft will not make instant stop due to an inertia force left to a certain extent after said halt. The control cam 37 is turned until the lobe 46 comes in a dent 39. The pawl 48 simultaneously comes in engagement with the ratchet wheel 43 to disengage the clutch mechanism 44.
