Title: Magnetic storage medium
Inventor: WADA YOSHIMITSU
IPC: G11B5/64
Filed: 2000-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent destruction of recorded information due to contact of slider of magnetic head with a medium by lowering the surface height of unit recording portion than the surface height of non-recording portion. SOLUTION: A magnetic disc medium 10 includes, on a disc type substrate 12, a number of small unit recording portions 14 arranged concentrically or spirally in the circumference direction and radius direction with an interval and non-recording portion 16 filling the areas between adjacent fine unit recording portions 14. Each small unit recording portion 14 is electrically independent to prevent crosstalk in the adjacent small unit recording portions 14, sets the surface height lower than the surface height of the non-recording portion 16 and recesses the small unit recording portions 14 from the surface of the non- recording portion 16.  Accordingly, even if a slider comes in contact with the medium surface, information recorded in the small unit recording portion 14 is not destroyed and adsorption of slider to the whole surface of medium can be prevented because fine roughness exists on the surface of medium.

Title: Device and method for modifying bearing axis of electromagnetic waves, radar device, its bearing axis modifying method, and radome for radar device
Inventor: OZAKI IWAO
IPC: G01S7/40
Filed: 2000-02-15
Abstract: PROBLEM TO BE SOLVED: To modify the bearing axis of electromagnetic waves. SOLUTION: An inclination θ is formed in the surface 22 and back surface 24 of a radome 20 which functions as a cover for a transmitting antenna 14a to transmit millimeter waves as electromagnetic waves and a receiving antenna 14b to receive reflected waves. As the refractive index of air is different from that of the radome 20, it is possible to refract millimeter waves by the Snell's law. By previously forming a plurality of radomes 20 with different inclinations θin the surfaces 22 and back surfaces 24 and selecting one radome 20 from among the plurality of radomes 20 according to the inclination of the bearing axis of millimeter waves, the bearing axis of millimeter waves is modified. Only by replacing the radome 20, it is possible to modify the bearing axis of millimeter waves and to prevent the increase of the number of components.

Abstract: PROBLEM TO BE SOLVED: To provide a non-contact IC card whose manufacturing process is simplified and whose conductive resistance can be made small, an RFID device (radio frequency identification) used for a TAG for physical distribution, etc., and its manufacturing method. SOLUTION: An antenna coil 16 that is formed on an insulation substrate 10 and is for performing radio communication is formed by performing press punching of metal foil such as Cu, Al, Au, Ag, into a coil shape by a sharp blade made of metal etc. The manufacturing process is simplified because a coil pattern is not formed by an etching process but by press working by the sharp blade. The conductor intervals of the antenna coil can be made narrow as 0.1 to 0.2 mm, which is remarkably narrower than in the conventional practice. As a result, the conductive resistance can be made small and a radio characteristic can be improved because a coil conductor width can inevitably be large.
