Title: Floating head slider utilizing negative pressure and rotary disk memory device
Inventor: TAKEUCHI YOSHINORI
IPC: G11B21/21
Filed: 1993-05-19
Abstract: PURPOSE:To maintain nearly the specified flying height of the slider in the radial direction of a reading medium, thereby averting the adhesion of dust on an inflow side bearing surface and suppressing the fluctuation in the flying height with the external disturbance at the time of seeking. CONSTITUTION:This floating head slider has a pair of side rails 15, a cross rail 18 disposed on the inflow side of a center rail 20 mounted with a transducer 11 and inverted step-shaped recessed parts 19 enclosed by these rails. Side rails 15 are provided with constricted parts 21 nearer the inflow side from the center and have a shape which increases in the floating surface width toward the outflow side and does not arrive at the outflow end. The cross rail 18 arrives at the inflow end and is formed of nearly the same plane. Tapered parts are abolished. Both sides of the inflow end may be provided with the second recessed parts. As a result, the positive pressure of the side rails is reduced, the speed characteristic for floating is thus maintained nearly constant even if the negative pressure is decreased by the miniaturization of the slider.

Title: Power generation method by rotation of magnetic force
Inventor: MOCHIZUKI HIROSHI
IPC: H02K53/00
Filed: 1994-04-18
Abstract: PURPOSE: To obtain a power generation method in which electric power can be generated by a method wherein permanent magnets are used, their attractive faces and repulsive faces are arranged alternately and rectangular permanent magnets are bundled so as to face them. CONSTITUTION: About four magnets (MTs) 2 are used, and they are arranged in such a way that their attractive faces and repulsive faces differ every other magnet. Two or four MTs 1 which are rectangular are bundled. In the MTs 2, their attractive faces and repulsive faces are arranged alternately. When the MTs 1 are turned, the attractive faces and the repulsive faces for the MTs 1 agree with the attractive faces and the repulsive faces for the MTs 2. Thereby, the attractive faces and the repulsive faces for the MTs 1 stop at joints of the attractive faces and the repulsive faces for the MTs 2. In the joint parts, the MTs 1 are turned by a motor 48, all faces for the MTs 2 are turned by themselves. When the MTs 1 are turned, the MTs 2 are turned by magnetic forces of the MTs 1, 2.  In this case, the magnetic forces are squared by the number of magnets for the MTs 1 according the the law of magnetic force energy. A force which is 16 times is generated in the MTs 1. In addition, when several MTs 1 are attached to the circumference of the MTs 2, the force is amplified by the number of magnets.

Title: Light diffusion sheet
Inventor: ONO YOJI
IPC: G02F1/13357
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To obtain a light diffusion sheet of which luminance distribution of light emission surface can be made uniform since the parallel light-beam transmissivity is small and the total light-beam transmissivity is high, and is thin, light in weight, and is flexible and can easily be installed on a curved surface by providing the light diffusion sheet which is made of woven fabric having a specific difference between total light-beam transmissivity and parallel light-beam trasmissivity specified. SOLUTION: The light diffusion sheet is formed of a woven fabric having a >=40 difference between total light-beam transmissivity and parallel-light light beam transmissivity. So that the woven fabric has this light-beam transmissivity difference, the diameter of the fiber is preferably 1μm-5mm, specially, 10μm-1mm. When the fiber diameter is <1μm, the woven fabric easily diffuses and reflect light, but when the diameter of the fiber exceeds 5mm, the flexibility of the woven fiber is spoiled and its use for a curved surface is disabled, so that its use range narrows down. This woven fabric is formed substantially of monofilament fiber, but multifilament fiber may be used at need and there is no problem in this case as long as the total fineness is within this range.
