Title: Noise filter
Inventor: TEJIMA MAKOTO
IPC: H03H7/09
Filed: 1987-09-16
Abstract: PURPOSE:To realize miniaturization, light weight, and low price and to increase a damping quantity, by using prescribed amorphous magnetic alloy as an inductor magnetic core consisting of a noise filter. CONSTITUTION:A common mode choke coil 1 and a normal mode choke coil 2 are used in both activating lines of the noise filter, and the noise filter of low-pass filter type in which a capacitor 4 is inserted between the activating lines and a capacitor 5 between the activating line and the ground is constituted. A ferrite core whose effective permeability is around 4000 is used in the magnetic core of the common mode choke coil 1. As the magnetic core of the normal mode choke coil 2, the magnetic core in which a micro crystal grain is distributed by a heat processing after winding a ribbon of iron amorphous alloy on the core and whose effective permeability of inductor is adjusted at around 200-1000 is used. In such a way, since high permeability can be obtained, it is possible to miniaturize the filter, and also, to suppress the lowering of the effective permeability due to the superposition of current at a low level, then, to increase the damping quantity.

Filed: 1993-09-20
Abstract: PURPOSE:To obtain a magnetic diskhaving stable durability by setting the surface roughness of a magnetic disk in the radial direction to a predetermined value and forming a protection layer with amorphous carbon film. CONSTITUTION:A lower layer of Cr is formed on the Ni-P plated aluminum substrate, a magnetic layer of Co-12Ni-2Ta is formed thereon and a protection layer of amorphous carbon is then formed thereon sequentially by the sputtering method. Moreover, the protection layer is then coated with a liquid lubrication agent of fluorine compound to form a magnetic disk. The surface roughness of the disk in the radial direction is expressed by the formula, Pc(+100A)>=30, in the reference length of 250mum. In above formula, Pc(+100A) indicates a total number of peaks in the reference length, when the center line crosses once or more the roughness curve, it is considered as one peak under the condition that one peak count level parallel to the center line is provided at the position of 100Angstrom  on the upper side of the center line of the roughness curve. Thereby, a magnetic disk having stable durability can be obtained.

Title: Rolling bearing
Inventor: HILLMANN REINHART DR ING
IPC: F16C27/06
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of abrupt acceleration and malfunction in lubricating accompanied therewith by arranging an elastic member which is flexed in the diameter direction between an outer diameter of a shaft and an inner diameter of each small rolling bearing. SOLUTION: A center of a small diameter portion of a shaft 10 is dislocated in a diameter direction from an axial center or rotational axis of a cylindrical roller 7 arranged between raceway track surfaces 2 and 5. A hole 18 of an elastic member 17 formed as flexible ring disc is eccentrically dislocated in a diameter direction in an assembled state. The elastic member 17 applies diametral force due to deformation to the cylindrical roller 7 through a small rolling bearing 14.

As a result, the cylindrical roller 7 is rotated together with the outer ring 6 for preventing malfunction in lubricating. During operation of the roller bearing, the roller in not stopped in a loadless area of the roller. It is thus possible to prevent in malfunction in lubricating and elongate a life of the bearing.

Abstract: PURPOSE:To separate and recover without failure even small pieces of non- magnetic metal by decreasing the area of a magnetic pole surface confronting the inner surface of a cylindrical piece of permanent magnet smaller than that of a magnetic pole surface set on a rotary body. CONSTITUTION:A permanent magnet piece (m) is formed with pair of left and right plane side faces (a), (a), a pair of left and right vertical faces (b), (b) extending linearly downward adjacent to the side faces, a top face (c) as a part of the cylindrical shape forming a magnetic surface, a pair of front and rear plane faces (d), (d) vertically extending on the both sides of the top face (c), and a plane base (e). A pair of the side faces (a), (a) are inclined in the directions, the upward extensions intersecting mutually. Therefore, the area of the top face (c) is smaller than that of the base (e). In this way, the large flux density from the outer magnetic pole surface of the permanent magnet piece (m) increases the magnetic induction enough to separate and recover efficiently even though pieces of aluminum on a belt conveyor are small.

Filed: 1990-09-04
Abstract: PURPOSE:To obviate the sticking of toners and to prevent the generation of fogging as well as to eliminate unequal exposing so as to prevent the generation of scumming by forming at least one color of picture elements by reversal development. CONSTITUTION:The picture elements 4 of the 1st color are formed by development on a photoconductor constituted by laminating a conductive band layer 6 and a photoconductive band layer 5 on a glass substrate 7. The photoconductor is then subjected to negative electrification by using an electrifying device 1 connected to a power source 2 for corona discharge. Namely, picture element parts of the 2nd color are irradiated with UV light 8 by using a mask 9 to remove the charges in the picture element parts. The toners are stuck to the parts where the charges are removed by executing the development using the negatively charged toners 10, by which the picture elements 11 of the 2nd colors are formed. The picture elements 12 of the 3rd color are thereafter formed in the same manner, by which the color filters of the three colors are formed. The generation of the scumming and fogging by the toners of the 2nd and subsequent colors is prevented by incorporating the reversal development into the production process.
