Title: Magnetic force method for measuring form
Inventor: KUNIEDA MASANORI
IPC: G01B7/00
Filed: 1992-03-04
Abstract: PURPOSE:To remove noise to improve the S/N of output signal, and improve the precision of measurement by working an alternate magnetic field to oscillate a measuring element. CONSTITUTION:An oscillator 10 generates an AC output and applies it to an exciting coil 5. The coil 5 generates an alternate magnetic field to oscillate a measuring element 4. Since the magnetic flux emitted from the top end of the measuring element 4 is formed in the normal direction to a surface 8 to be measured, the central line of the measuring element 4 tries to conform with the normal in the measuring position of the surface 8 to be measured. Thus, the moving direction and inclination of the measuring element 4 are detected by displacement detecting elements 9X, 9Y, 9Z in each axial direction, the normal in the measuring point of the surface 8 to be measured is detected from the final stable posture of the measuring element 4, and the direction of the surface 8 to be measured is judged. A signal processing unit 12 detects a fixed measured value never influenced by noise by taking the difference between the maximum value and minimum value of each output signal of the elements 9X, 9Y, 9Z. The distance between the measuring element 4 and the surface 8 to be measured is detected from this measured value.

Title: Pump device
Inventor: YAMORI MASAHIRO
IPC: F04B9/06
Filed: 1986-04-09
Abstract: PURPOSE:To change a pump to the low load running state automatically by constituting the pump so that the reciprocating action of a reciprocating guide operated by a driving part can be suppressed by the compression effect of a piston controlling spring when the pump pressure increase over the usual working pressure because the discharge port is closed or similar events occur. CONSTITUTION:When the pump pressure is under the usual working pressure, a reciprocating piston 21 and the piston rod 17b of a differential piston 17 are unified. At the intake stroke of the piston, the differential piston 17 is moved to the right via the reciprocating guide 21 by turning an eccentric shaft 11. Therefore a discharge valve 20 is closed and the intake valve 4 is opened so that the intake action is performed. On the other hand, when a spray nozzle connected to the discharge port 7 is closed and the pressure inside a pump casing 16 is therefore increased over the usual working pressure of the pump, the spring 24 is compressed to suppress the reciprocating action of the reciprocating guide 21. With the differential piston 17 performing no pumping action, turning a driving shaft 10 causes a driving part 9 to run in the low load state.
