Patent JP-H02123300-A (JP)
Title: Structure of curved blade for moving fluid
Inventor: KIYO INTOU
IPC: B63H1/26
Filed: 1988-11-02
Abstract: PURPOSE: To permit a fluid to be sucked also from a range except a cylindrical range of a front end of each vane and to flow also to a range except the cylindrical range by providing curved vanes each of which is attached to a hub or a boss rotationally operated by a shaft and is bent to a semi-spherical shape. CONSTITUTION: Each vane 1 has a curved structure with a plurality of successively disposed slant faces 3 to 7 following an angle variation towards a direction of a shaft 12. Due to this structure, a fluid is dispersed or agitated within a wide angle range from substantially zero to 180 degrees by a fan for air blasting or a pump for fluid movement. Further, the fluid is sucked from a wide angle range substantially from zero to 180 degrees by a screw or propeller for propulsion. Since the fluid is intensively evacuated as passing through the curved vane 1, a strong and effective propulsive force can be obtained.

Title: Device for detecting amount of thickness change for reference of steel plate edge
Inventor: TORIO JUNICHI
IPC: G01N27/90
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To accurately detect the amount of sagging of a steel plate edge. SOLUTION: With eddy current sensors 1 and 2 with an E-type core, the eddy current sensor 1 is arranged at a position for generating a thickness change due to the generation of 'sagging' of a steel plate L, and the eddy current sensor 2 is arranged at a position deviating from an edge in the direction of plate width toward a direction that orthogonally crosses the edge and is arranged at a position for preventing the thickness change from occurring due to the generation of the 'sagging'. Detection signals SEG and SIN of the eddy current sensors 1 and 2 are converted to distance DEG and EIN from each of the eddy current sensors 1 and 2 to the steel plate L to calculate the difference ΔD. When no 'sagging' is generated, the difference ΔD becomes nearly zero sic the thickness of the edge part of the steel plate L and the inner position is the same.  On the other hand, when 'sagging' is generated, the distance DEG becomes large and hence the amount of sagging ΔD becomes large since the thickness of the inner position is invariable but the thickness of the edge part becomes thin. When the amount of sagging ΔD exceeds a limit value Dmax, it is judged a trimmer blade needs to be replaced, which is outputted to an output device 7 for reporting to an operator.
