摘要： A micro-rotating device has a rotor 200 (of diameter not more than 1.5 cm), a shaft 202 threaded through the rotor 200, and a shaft holder 207 for holding the shaft. The shaft holders are formed by etching an Si substrate 501 to form multiple shaft receiving openings 508. The rotors and shafts too are formed from respective Si substrates 301, 401. The rotors 200 are located over the shaft holders 207, and the shafts threaded through the rotors 200 into the openings 509 and attached there by a wafer bonding process. Then the substrate 501 is partitioned to give individual motor elements. Protrusions 206 extend from the rotor in the direction towards the stator to space the rotor from the shaft holder.

摘要： A MEMS (micro-electromechanical system) device having a rotor 44, a stator 43 and a shaft 27 connected to the stator 43 and around which the rotor 44 rotates. Grooves 47 are formed in a portion of the rotor 44, such that when the rotor 44 rotates an air bearing is formed for supporting the rotor 44 and maintaining its distance from the shaft 27 and stator 43. The rotor 44 is formed from joining two substrates 13, 23. One of the substrates 13 includes a surface having openings 7 including frustoconical walls, and one of the substrates 23 includes a surface having openings 15 including walls perpendicular to the surface of the substrate. The openings in the two substrates are in register with each other so that pairs of the openings form chambers 24. Each chamber 24 is provided with a shaft 27, which is positioned with a wide section of the shaft trapped in the chamber 24. The wide section of the shaft has a frustoconical surface facing the frustoconical walls of the chamber 24.

摘要： The present invention provides a high quality magnetoresistance effect type magnetic head having an increased reproduction output and capable of applying a uniform bias magnetic field to a magnetoresistance effect layer without increasing an impedance. The magnetoresistance effect type magnetic head according to the present invention includes: a magnetic layer 11 magnetized approximately in a vertical direction to a plane 14 opposing to a magnetic recording medium; a non-magnetic insulation layer 12 formed on the magnetic layer 11; and a magnetoresistance effect layer 13 formed on the non-magnetic insulation layer 12 and exhibiting the magnetoresistance effect. In the longitudinal type magnetoresistance effect type magnetic head according to the present, the detection current supplied to a magnetoresistance element is prevented from flowing into a hard magnetic film to lower the head reproduction output.

摘要： A wave plate capable of increasing a birefringence quantity and being made into a thin film, and a method of manufacturing the wave plate. The wave plate includes a substrate, whereon convex portions and concave portions are formed with a period less than or equal to the wavelength of light that is used therewith, columnar portions, wherein fine grains of a dielectric material are layered by oblique vapor deposition of a dielectric material from two directions, in a columnar shape on the convex portions in the vertical direction relative to the surface of the substrate, and interstices that are located on the concave portions and disposed between the columnar portions. Using birefringence from the fine grains of the dielectric material and birefringence from the concave/convex portions of the substrate allows increasing the birefringence quantity and making a thin film.
