摘要： A method for grinding a tape, and a device thereof are provided to adjust the force exerting on a projection unit by a head pin, adequately and to process the projection unit with high accuracy by limiting the variation of the force on exerted on the projection unit. A device for grinding a tape comprises a head pin, a tape grinding unit, a measuring unit, and a control unit. The front end portion of the head pin contacts with the other surface of the tape and moves along the vertical coordinate shaft of a substrate surface. The tape grinding unit is installed to grind a projection unit(22) by the surface of the grinding tape. The measuring unit is installed to measure the height of the projection unit. The control unit is installed to divide the height of the projection unit into the process range over two step and to vary the force exerting on the projection unit.

摘要： The pump has a rotor (32) with blades and a flat surface (34) containing numerous permanent magnets (35) and spiral grooves. It is enclosed in a housing (31) of non-magnetic material with a flat surface opposite that (34) of the rotor. A driving member (36) for the rotor has a magnet (37) above the housing and opposite those of the rotor, to which it is magnetically coupled. When the rotor is turned by the driving member, the grooves in the former generate thrust against the flat surface of the housing, so that the rotor is kept in a hovering position inside the housing. ADVANTAGE - Smooth delivery of liquid while keeping it clean, particularly for use in bio-technology.

摘要： A spindle assembly has a spindle 32 supported by a single journal bearing 33 having a large bearing width. The journal bearing is formed near both ends thereof with a plurality of circumferentially arranged gas supply restrictor nozzles 37. The spindle is supported by supplying compressed gas to the bearing clearance around the spindle. This arrangement prevents the spindle from running out of true. A pair of externally pressurised gas thrust bearings 35, 36 may also be provided.

摘要： An externally pressurized air bearing assembly comprises a cylindrical first bearing portion X having a journal bearing surface 2c, a thrust bearing surface 2d, and a plurality of bearing nozzles 2e, 2g; and a cylindrical second bearing portion Y having a thrust bearing surface 3b, and a plurality of bearing nozzles 3c. An annular groove 10 is formed between the outer surface of at least one of the first and second bearing portions and the inner surface of an outer case Z such that air can be supplied to the bearing nozzles via the groove and an axial passage 9 from a port formed in the outer case. The assembly supports a shaft 1 carrying a thrust plate 1a; air supplied through a further passage 6 and nozzles 2a impinges on recesses 1a1 on the thrust plate, thereby driving the shaft. The portion X may be of ceramics, resin, or graphite, and the portion Y may be of aluminium alloy.

摘要： PROBLEM TO BE SOLVED: To provide a pattern correction method of which noise is less, and in which a protruding part of the top face of a rib can be removed accurately. SOLUTION: In this pattern correction method, a polishing headpin 41 of which its tip part is contacted with the rear face of an polishing tape 40 is movably installed in the Z direction, a polishing tape head is made to be descended toward a normal top face 55 of the rib 13 from upward, Z coordinates Z1 is detected when the polishing head pin 41 starts moving upward than a reference position, and the protruding part 56 is polished up to the normal top face 55 from upward based on that Z coordinates Z1. Therefore, the noise is less because of using the polishing tape 40. Furthermore, the height Z1 of the normal top face 55 can be detected precisely. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PURPOSE:To prevent the lowering of concentricity between a main spindle and a tool and maintain the concentricity over a long period of time. CONSTITUTION:The rear end face 10a of a draw bar 10 is formed into the protruding spherical face, and the tip face 12a of a push rod 12 is formed into the flat face. The spherical face center of the rear end face 10a is on an axis. Since the tip face 12a of the push rod 12 and the rear end face 10a of the draw bar 10 are brought into contact always at one point on the axis, partial contact to be the factor of lowering of the concentricity between a collet chuck 9 and a main spindle 2 is not caused.
