The present invention relates to a method of discovering optimal conditions such as the rotational speed ratio of an abrasive cloth and a dresser, to improve the flatness of the abrasive cloth after it has been dressed. A narrow annular dresser having an inner diameter of at least the width of a wide annular utilization region of the abrasive cloth is pressed while rotating against the abrasive cloth which is fixed onto a turn table. A rotational motion is imparted to the abrasive cloth in the same direction as the rotation of the dresser and at a predetermined rotational speed. The abrasive cloth is dressed thereby in such a manner that there is a uniform distribution of distances through which the grindstone slides over various points within the utilization region of the abrasive cloth.

The present invention provides a headstock of a polishing machine, having a simple structure and capable of tracing a pad surface. The headstock of the present invention is formed of a spindle, a holder plate, a spherical bearing, and a plate spring. The holder plate is connected to a lower end portion of the spindle via the spherical bearing and the plate spring. A workpiece is attached to the lower surface of the holder plate. The spherical bearing has a center of tilting movement on a rotation axis of the spindle. The holder plate has a balance plate. The center of gravity of the holder plate including the balance plate coincides with the center of tilting movement of the spherical bearing. The plate spring has an axisymmetric shape. More specifically, the plate spring has an opening portion at the center and a plurality of arm portions extending to the outer periphery in the diameter direction. The plate spring is connected to the lower end of the spindle by use of first fitting holes which are formed along the inner periphery, and the plate spring is also attached to the holder plate by use of second fitting holes which are formed in the distal end of the plate spring. The first and second fitting holes are respectively located on small- and large-diameter circles which are concentrically arranged around the rotation axis of the spindle.

An insulating structure is formed that favorably maintains gap-fill capability of a narrow width pattern in a memory cell while also preventing the formation of cracks in an insulator in a peripheral circuit, and has the memory cell and peripheral circuit within the same layer. The present invention provides an insulating structure comprising a substrate and a circuit pattern formed on the substrate, wherein the circuit pattern has a narrow width region having a narrow width pattern of a width of 30 nm or less and a wide width region having a wide width pattern of a width of greater than 100 nm in the same layer, and the same insulating composition is formed within the narrow width pattern and within the wide width pattern.

A ball screw device or linear motion guide device has a seal member preventing dust and dirt from entering into a movable member of a linear motion guide device and seals out fine dust, dirt or like by surely contacting a seal to a shaft member without providing a large margin to the seal. The seal member includes a body portion mounted to the movable member and a lip portion contacting an outer portion of the shaft member, the lip portion has an oblique surface having an axial section inclining with respect to its axial direction, the body portion has an urging member urging the lip portion in a diameter direction of the shaft member and a reinforcing portion reinforcing the body portion. The urging member is located on the reinforcing portion side than the tip end of the lip portion in the axial sectional shape of the lip portion.

A first virtual storage and a second virtual storage share an external LU (Logical Unit) inside an external storage. The first virtual storage comprises a first LU, which comprises multiple first virtual areas and conforms to thin provisioning, and an external capacity pool, which is a storage area based on the external LU, and which is partitioned into multiple external pages, which are sub-storage areas. The second virtual storage comprises a second LU, which comprises multiple second virtual areas and conforms to thin provisioning. In a data migration from the first LU to the second LU, for a data migration from a first virtual area, to which an external page has been allocated, to a second virtual area, the first virtual storage notifies the second virtual storage of a migration-source address, which is an address of the first virtual area, and an external address, which is an address of the external page that has been allocated to this virtual area, and the second virtual storage stores a corresponding relationship between the notified migration-source address and external address.

A substrate earthing mechanism includes a plate-like spring extending toward a substrate in a direction parallel to a surface of the substrate, and a contact portion coupled to a tip end of the plate-like spring for coming into contact with the substrate to thereby provide electrical conduction therebetween. The plate spring and the contact portion are laid out so that a contact position at which the contact portion is in contact with the substrate and a layout position of the plate-like spring are substantially the same in position as each other in a direction at right angles to the substrate surface in the state that the plate spring is out of its elastic deformation.

A constant-temperature fluid supply system is provided with a first constant-temperature fluid supply apparatus and a second constant-temperature fluid supply apparatus. The first constant-temperature fluid supply apparatus has an input side to which a cooling fluid not controlled in temperature is supplied, and an output side from which a first constant-temperature fluid having a stable temperature is supplied. The second constant-temperature fluid supply apparatus has an input side to which the first constant-temperature fluid is supplied, and an output side from which a second constant-temperature fluid having a more stable temperature than that of the first constant-temperature fluid is supplied.
