<p><P>PROBLEM TO BE SOLVED: To solve problems of a hat with magnets that sufficient adhesive strength is not obtained because of a small adhesion area when attaching granular magnets directly onto the hat, and that an adhesion surface of the magnet peels off due to attraction between the magnets. <P>SOLUTION: The hat with magnets has the granular magnets attached on an attaching material, and the attaching material is adhered to the inside of the hat, while the direction of polarity of the magnets is aligned. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
