PRODUCT HAVING BIREFRINGENT PATTERN

PROBLEM TO BE SOLVED: To provide a product having a birefringent pattern, observing information on the opposite side from the observation side, and developing a latent image into a visible image by one sheet polarizer. SOLUTION: This product 101 includes a patterned optical anisotropic layer having two or more areas different in birefringent like a pattern. The article further includes a semi-transparent and semi-reflecting layer 13 having 30-95% light transmittance and 30-95% reflectance. COPYRIGHT: (C)2012,JPO&INPIT ...

SOLENOID DEVICE

PURPOSE: To precisely detect the rate and position of a driving coil by a method wherein a search coil is wound up not to be affected by the flux of driving coil. CONSTITUTION: The solenoid device is provided with a bottomed cylindrical yoke 18, a magnet 19 held by this yoke 18 and a columnar pole piece 21 fixed to the magnet 19 making a specific gap 20 between the yoke 18. A bottomed cylindrical bobbin 13 is arranged to be loosely inserted downward into the pole piece 21 while a driving coil 22 is fixed to the aperture lower end edge of the bobbin 13 to be suspended. Furthermore, a search coil 23 is wound around concentrically with the driving coil 22. This search coil 23 is wound around the bobbin 13 as if passing through the gap of the driving coil 22 while inversing the winding up direction bordering on the rewinding part 23c on almost central position in the long direction of the bobbin 13. Through these procedures, the shifting rate and position of the search coil 23 can be precisely ...
