Inventor: LIEN CHANG WANG
IPC: G11B5/39
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a reading sensor with which formation of short-circuit path between plural electrically conductive layers of a reading sensor is prevented and interlayer boundary surface control of high grade is realized and a manufacturing method thereof. SOLUTION: A SDT(spin-dependent tunnelling effect) reading sensor has a first ferromagnetic material(FM) layer and a second FM layer separated by an insulating layer. The first FM layer and the second FMN layer are substantially electrically separated from each other. A sidewall of the SDT reading sensor substantially does not contain a conductive path between the first FM layer and the second FM layer. Further, a surface of the second FM layer extending substantially parallel to an air- bearing surface retreats from the air-bearing surface. A manufacturing method of the SDT reading sensor contains a process for depositing the first FM material layer, a process for depositing an intermediate insulating material layer on the first FM material layer and a process for depositing the second FM material layer on the intermediate insulating material layer.  The second FM material layer and the intermediate insulating material layer are subjected to etching. The etching is stopped before the first FM material layer is etched.

IPC: G02B27/09
Filed: 1988-11-17
Abstract: PURPOSE:To reduce the number of parts required for an optical isolator by using a magneto-optical crystal formed with hologram on the surface as a Farady rotator and transforming the form of a light beam passed through the magneto-optical crystal by means of the hologram on the surface of the crystal. CONSTITUTION:Linearly polarized light passed through a polarizer 11 out of the light emitted from a semiconductor laser element 1 receives a Farady effect when the polarized light passes a magneto-optical crystal 4 and its polarizing direction is turned by 45 deg.. At this time, the light emitted from the element 1 is transformed into parallel beam of light by means of a Fresnel lens 12 and emitted through an analyzer 7, the transmitting polarizing direction of which is arranged at 45 deg. to the polarizer 11. On the other hand, in the reflected light to the element 1, the component parallel to the transmitting polarizing direction of the analyzer 7 is passed through the analyzer 7, and receives a Farady effect of 45 deg. when the component is passed through the crystal 4 in the course of the component concentrated to the element 1 by means of the lens 12. The reflected light received the 45 deg. Farady effect cannot pass through the polarizer 11, because the polarizing direction is further turned by 45 deg. due to non- reciprocity of the Farady effect.

Title: Preparation of salt of octyloxy substituted diphenyliodoniumhexafluorometalloid
Inventor: JIEEMUSU MITSUGU FUKUYAMA
IPC: C07B61/00
Filed: 1990-10-31
Abstract: A one pot method is provided for preparing an (octyloxyphenyl) phenyliodonium tosylate and the corresponding hexafluorometalloid salt. n-Octylphenyl ether is initially prepared using a halooctane and phenol in the presence of a phase transfer catalyst followed by the addition of iodobenzene, a peracid, and p-toluene sulfonic acid. The resulting (octyloxyphenyl)phenyl iodonium tosylate can be directly metathesized after an optional treatment step with an alkali metal hexafluoroantimonate salt.

Title: Dynamic pressure air bearing, motor with the bearing, and light polarizer
Inventor: TAKAHASHI MASAHIRO
IPC: H02K7/08
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To provide a dynamic pressure bearing to ensure stable rotation and allowing suppression of the costs. SOLUTION: At the peripheral surface of a shaft 14, three grooves 62 for lowering the dynamic pressure are formed at constant spacing (120 deg. intervals) in the circumferential direction. When a sleeve 40 rotates round the shaft 14, a dynamic pressure is generated between the shaft 14 and sleeve 40, and the area free of such grooves 62 has a lower pressure than the area with grooves 62. The dynamic pressure generating area differs in the two areas with and without grooves about the axis interposed, and according to the formula that the force = pressure × area, a force F directed outward in the radial direction on the side free of grooves will be generated in the sleeve 40. Because such a force F generated between the grooves 62 acts in three places at equal intervals, the sleeve 40 is supported at three points, and a stable rotation can be generated.

IPC: H03H17/06
Filed: 1989-11-13
Abstract: PURPOSE:To improve the tracking performance by updating a filter coefficient according to a specific update algorithm and applying positive uniform random number to a weight coefficient from a fixed value. CONSTITUTION:An input signal x[K] inputted to a main FIR(Finite Impulses Response) filter 13 is subjected to FIR filtering depending on a filter coefficient ai[K] stored in a filter coefficient storage register 15 and the resultant signal is outputted. Moreover, a square calculation part 14 squares the input signal x[K] to calculate x<2>[K] and a sub FIR filter 16 outputs a weighted square calculation result SIGMAalphaix<2>[K-i]. A weight coefficient alphai[K] stored in a weight coefficient storage register 17 is decided based on a positive uniform random number generated from a uniform random number generating section 18. A division section 21 divides a difference between a filter output of the main FIR filter 13 and an output of an unknown system 12 by a value being a sum of a weighted square sum and an offset, a filter coefficient revision section 23 updates the filter coefficient ai[K] and the result is transferred to the main FIR filter 13. Thus, the tracking performance is improved.
