Title: Grinding apparatus, its manufacture and manufacturing device
Inventor: MEYER HANS-ROBERT DR ING
IPC: B24D7/14
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To provide a polishing tool having the long service life even if a load is nonuniform by variously or continuously changing a physical characteristic and/or the volume content rate of a component of a polishing layer in the axial direction of the polishing layer. SOLUTION: Polishing grains of a polishing layer 14 are shown by dotted spots 15. The fact that the distribution of grains changes in the shaft direction can be understood. The maximum concentration is formed in a tip part or an apex part 16 having a maximum radius, and this concentration reduces toward the side part direction of the polishing layer. In this case of a triangular cross section, reduction in the concentration becomes linear. In the case of a different-shaped cross section, since a passage of the concentration in the shaft direction may be a different passage from the one having a triangular cross section, a required process in only to select a concentration passage so that the action of abrasion of the polishing layer 14 is adapted to a quantity of a material to be polished and removed from a workpiece.

IPC: G11B5/09
Filed: 1992-10-01
Abstract: PURPOSE: To provide a digital signal reproducing device in which the complexity of an equalizer filtering means, that can supply equalized output signals having allowable signal quality, is reduced. CONSTITUTION: The device, which reproduces digital signals from the tracks of a magnetic recording carrier 20, is provided with a magnetic reading head 21, which has a magneto-resistive(MR) element 107 and an equalizer filtering means 23 which equalizes the output signals of the magnetic head 21. The means 23 has an IIR(infinte impulse response) filtering means 29 and an FIR (finite impulse response) filtering means 30. The means 29 equalizes the magnitude and the group delay of the signals, which are supplied to the input side, in the low frequency region of the signal frequency range. The means 30 at least equalizes the magnitude of the signals, which are supplied to the input side, in the high frequency region of the signal frequency range. The MR head has a front surface side section and a back surface side section along the running direction of the recording carrier.  One of a side section 41 has a larger magnetic shielding than the magnetic shielding of an other side section 41.

Title: Low pass filter
Inventor: MIYAZAKI KOZO
IPC: H03H7/075
Filed: 1984-12-14
Abstract: PURPOSE:To decrease number of components and to attenuate sufficiently even a large interference wave by forming an LPF with a coil, a capacitor and a through-capacitor. CONSTITUTION:The LPF is formed by the coil 9, the capacitor 10 and the through-capacitor 8. The attenuation characteristic at high frequencies is not decreased in the through-capacitor 8 apart from a lead wire type capacitor whose inductance gives an effect. Since the LPF consists of only two stages of capacitors (capacitor 10 and through-capacitor 8), the distance between common terminals of the capacitor 10 and the through-capacitor 8 is decreased very much and the impedance between both to the common level is lowered, the interference frequency component is attenuated sufficiently.

Abstract: PROBLEM TO BE SOLVED: To greatly lower vibration noise by forming a vibration isolating member made of rubber elastic body into a bobbin shape provided with elliptic flanges in both ends and arranging it so that the elliptic flange tip is brought into contact with a fan motor main body. SOLUTION: A fan motor 3 connected to a blower is fixed to a motor base through several positions by means of fixing bolts via rubber vibration isolators 6. When the rubber vibration isolator 6 provided with elliptic flanges is installed to the fan motor 3, the tip (a') of the elliptic flange is compressed to the fan motor 3 main body, so that the rubber vibration isolator 6 is supported in the points (b), (c) toward the anticenter direction of the fan motor 3 by means of repulsion force of rubber applied from the point (a'). In this way, an elastic characteristic naturally provided in the rubber is always maintained in the A part of the rubber vibration isolator 6, so that electromagnetic vibration generated during the rotation of the fan motor 3 can be easily absorbed.

Title: Manufacturing method for semiconductor device
Inventor: UMEDA KOJI
IPC: H01L29/78
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To provide the method for forming a silicon oxynitride film with improved TDDB characteristics. SOLUTION: While a silicon substrate 1 is heated, a gas including N2O which is not thermally decomposed is put in contact with the surface of the silicon substrate 1 to form a silicon oxynitride film 3 on the surface of the substrate 1. The silicon oxynitride film 3 obtained in this way, contains no SiNO2 chemical bond unit at any part in the film thickness direction. Nitrogen in the silicon oxynitride film 3 formed in this method is generated locally at an interface between the silicon substrate 1 and the silicon oxynitride film 3. In addition, there is no chemical bond of SiNO2 existing at the interface or at a part other than in the interface. In this case, TDDB characteristics of the silicon oxynitride film 3, having nitrogen distributed locally at the interface, is improved as compared with that of a silicon oxynitride film 3 having nitrogen distributed uniformly in the film.

Filed: 1994-10-04
Abstract: PURPOSE: To set any drop in view of tensile strength to be produced by eccentricity between an anchor rod and a clamping bolt uniformly within the extent of tolerance. CONSTITUTION: A mark 10 displaying an eccentric value from a weld position of an anchor rod welded to the underside is preset to the top of an anchor plate 1, and at the time of welding a clamping bolt, on the basis of the mark 10, an eccentric value lying between the bolt and the anchor rod is checked that it is within the extent of tolerance and thereby their welding is carried out. As for this mark 10, a concentric circular mark 12 displaying the eccentric value from the weld position with the weld position of the anchor rod as the center is used for the end. It may be used as a mark displaying the maximum eccentric value capable of allowing an outermost circular mark 12f.  Therefore, with this simple constitution, at a time when the bolt is welded to the anchor plate, the eccentric value from the weld position of the anchor rod and a fact that whether the eccentric value is within the extent of tolerance or not are judgeable at a glance.

Title: Photoelectirc voltage sensor and current sensor
Inventor: KUMEGAWA HIROSHI
IPC: G01R15/24
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To compensate an error caused by an optical bias change such as the shift of phase difference of a λ/4 plate generated in association with temperature change in an photoelectric voltage sensor for detecting voltage from the transmitted light quantity of an optical path based on the optical rotation of an electro-optical element corresponding to applied voltage. SOLUTION: An S-component and a P-component with the plane of polarization orthogonal to each other, of output light from an output side polarized analyzer 28 are respectively subjected to photoelectric conversion by photodiodes 32, 33, and the output is made direct current by low-pass filters 35, 36 and then divided by each other by a divider 37. Either one of the S-component and P-component is increased in relation to an optical bias change, and the other is decreased. The output of either one of the photodiodes 32, 33 is therefore computed for correction, corresponding to the divided result so as to be able to eliminate an error caused by temperature change. High accuracy measurement can thus be performed over a wide temperature range even in case of using a general purpose product as an electrooptical element 27.
