Title: Spindle motor and magnetic disk device mounted with the same
Inventor: SANADA YOTARO
IPC: H02K29/00
Filed: 1991-12-20
Abstract: PURPOSE:To suppress the vibration of a cover and a base which constitute a disk inclosure by reducing the transmission of vibration, generated at an armature constituting the spindle motor for the magnetic disk device, to a shaft. CONSTITUTION:The spindle motor consists of a spindle hub 2, a bearing 3, the shaft 7, and a magnet 4, a yoke 5, and the armature which constitute a motor driving system. A housing 8 which is engaged with the base 11 is coupled with one end of the shaft 7 and the cover 12 is coupled with the other end. The armature 6 is fitted to the shaft 7 across rubber 13 which has an attenuating function. The vibration of the armature 6 is absorbed by the rubber 13, so the transmission to the shaft 7 is reduced, and consequently the vibration of the cover 12 and base 11 is reduced.

Filed: 1992-12-17
Abstract: PURPOSE:To provide a spindle motor which has a group of grooves for increasing a load support pressure in a dynamic pressure radial bearing and hence is suitable for the reduction of thickness, which has a high stability in radial revolution support, which is suitable for the reduction of the outside diameter by reducing the thickness of a sleeve, and which facilitates overall processing because of small distortion and deformation caused by the formation of slits. CONSTITUTION:A radial dynamic pressure bearing R is made up of a substantially cylindrical inner periphery section of a sleeve 32a and a part of a large diameter section 16b of a fixed shaft body 16 which corresponds to the sleeve 32a. A group of grooves G for increasing a load support pressure are made by forming a number of grooved bodies 'g' along the inner peripheral surface of the sleeve 32a in a rotationally symmetrical pattern. The grooved bodies 'g' are made up of axial grooved portions g1 that occupy the axial center area of the inner periphery of the sleeve 32a, first tilted grooved portions g2 that upwardly extend in a given circumferential direction from the upper ends of the axial grooved portions g1 at an inclined angle, and second tilted grooved portions g3 that downwardly extend in a given circumferential direction from the lower ends of the axial grooved portions g1 at an inclined angle.

Title: Intra-chip communication data compression technique
Inventor: KAMEYAMA MITSUTAKA
IPC: G06F7/00
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To parallel perform a collation operation in compression and expansion and to perform efficient communication based on data compression between modules in a processor. SOLUTION: Data is compressed in a data transfer mode by using a memory and computing element integrated type parallel processor architecture for compressing and expanding data. Transmitting data is compressed in a compression module 3 of a module A1 and is transferred to a module B2. An expansion module 4 of a module B2 expands received data. In such a case, 'instantaneously decodable' algorithm, that is, such algorithm as to start to expand just after a module B receives data is used as compression algorithm. Then, it is possible to overlap expansion time 8 and transfer time 7.

Title: Electrostatic filter
Inventor: KIMURA KAZUSHI
IPC: B01D39/08
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To decrease the deterioration of performance due to dioctylphthalate oil mist by electrostatically charging a depositing component comprising at least a specified copolymer resin and a specified formaldehyde resin on the base component containing a mixture of wool and thermoplastic synthetic fibers. SOLUTION: A felt or nonwoven fabric comprising wool and thermoplastic synthetic fibers is impregnated and solidified with a resin liquid which is prepared by dissolving and mixing a para-tertiary butylphenol formaldehyde resin (MK resin) and a fluorine-based perfluoroalkylacrylate copolymer resin (PFA copolymer resin) in an incombustible org. solvent such as trichrene. The base body component with deposition and solidification of the resin component is further subjected to electrification to add electrostatic charges to the body. The PFA copolymer resin has high oil repelling property, and when the resin is mixed with MK resin, the PFA copolymer prevents or suppresses permeation of oil into the MK resin. Thereby, trapping efficiency for oil mist and dust can be significantly improved.

Filed: 1996-12-30
Abstract: PROBLEM TO BE SOLVED: To obtain a measured value from which the influence of surface roughness of a measuring site is excluded by calculating an average value of a plurality of measured data measured at a plurality of positions on the same surface by excluding maximum and minimum value sides. SOLUTION: The inner diameter measuring apparatus 1 inserts, for example, a measuring head 12 to first to fourth crank holes 3 to 6 of openings cut at a work 2, measures inner diameters, for example, at each 1/1000 sec while moving it along an inner wall surface 13, averages them for each predetermined times, and stores them in a memory. When the averaged data arrives at a predetermined number, movement of the head 12 is stopped, data of minimum and maximum values are excluded for predetermined times from the averaged data stored in the memory, residual data are averaged as measured value of the inner diameter, and compared with a reference value. When one of the data disposed at intermediate order of the minimum and maximum values of the averaged data is selected as the measured value, data processing time can be shortened.
