The present invention provides a crash stop which is capable of adjusting shock absorptivity by employing the same elastic material and where the mounting and demounting operations are easy. A metal pin has a recess in its intermediate portion. An elastic body has three blade portions. In a crash stop, the metal pin is press fitted into the pin inserting hole of the elastic body, and the portion between the support portion and the knob portion of the metal pin is covered with the elastic body. In the boundary between the intermediate portion of the metal pin and the elastic body, a cavity is formed. The support portion is fitted into the crash stop support hole of the base so that it can be freely pulled out and inserted. At this time, the upper end of the blade portion contacts the inner side surface of the crash stop inserting hole of the upper yoke and is contracted, and by the frictional force generated between the crash stop inserting hole and the upper end of the blade portion, the crash stop is locked. The abutting shock of the stopper arm of an actuator is absorbed with cooperation of the elastic body and the cavity.

A hard disk drive that can suppress an increase of fluttering and power consumption at high rotation speed by increasing the seek speed of a magnetic head is disclosed. An enclosure case has a 3.5 inch form factor, and a magnetic disk has an outer diameter of, for example, 84 mm. A center of the magnetic disk is shifted from a center of the enclosure case in the width direction. Owing to this, by designing a larger voice coil, it is possible to increase the driving speed of the actuator.

To provide a piezoelectric sensor that never sacrifices work properties such as when a lead wire is to be soldered to one of a pair of electrodes of a piezoelectric sensor, and the other electrode is to be bonded and fixed to a predetermined member with an adhesive, and to bond the ground electrode of the piezoelectric sensor to the conductive portion of the object member with an adhesive so as to be fixed and connected electrically, thereby preventing a short-circuit that might occur between the two electrodes due to extruded and stuck adhesive, and to provide an easier method for testing whether or not the ground electrode is connected electrically to the conductive portion of the object member. A piezoelectric sensor has two electrodes that are formed with different materials appropriate for soldering and bonding by an adhesive. The ground electrode of the piezoelectric sensor is bonded to the object member with a non-conductive adhesive so as to be connected electrically. Furthermore, the capacity between the output electrode of the piezoelectric sensor and the object member is measured to check the electrical connection between the ground electrode and the object member.

A stator magnet according to a first embodiment of the present invention forms a voice coil motor with a closed coil. The closed coil is supported by an actuator arm in a rotatable manner and at a predetermined rotation angle. The closed coil has first and second side edges that extend along different lines in radial directions whose center is a center of rotation of the actuator arm. It also has an outer edge that connects edges of outer sides of the first and second side edges with viewed from the radial direction, and extends along an arc whose center is the center of rotation. A first magnetic pole region is located within a moving area of the first side edge to act on the first side edge. A second magnetic pole region is located within a moving area of the second side edge to act on the second side edge. The polarity of the second magnetic pole region is opposite to the polarity of the first magnetic pole region. A third magnetic pole region is located within a moving area of the outer edge to act on the outer edge. The polarity of the third magnetic pole region is the same as the polarity of the first magnetic pole region.

A method of forming an interconnect for a semiconductor device using triple hard layers, comprises: forming a first hard layer serving as an etch stop layer on a metal interconnect-formed dielectric layer; forming a second hard layer on the first hard layer; forming a dielectric layer on the second hard layer; forming a third hard layer on the dielectric layer; forming a hole through the third and second hard layers, the dielectric layer, and the first hard layer; and filling the hole with metal to establish an interconnect. The second and third hard layers are each made of carbon-doped silicon oxide formed from a source gas and a redox gas, while controlling the carbon content in the second hard layer as a function of a flow rate of the redox gas.
摘要:
A base plate of a stainless-steel body material formed by pressing is polished and cleared of burrs by means of an abrasive material that consists mainly of Fe2O3 in a polishing process. The polished base plate is heated to a heat treatment temperature for solid solution in a reducing atmosphere in a heat treatment process. In this heat treatment process, an oxide in the constituents of minute fragments of the abrasive material in the surface of the body material of the base plate is reduced to leave iron, which is dispersed into the body material.

A substrate-supporting apparatus, wherein a substrate is not warped or distorted and a film with uniform thickness is formed, is a semiconductor substrate-supporting apparatus which supports and heats semiconductor substrates inside a vacuum-pumped reaction chamber. On the substrate-supporting surface of the semiconductor substrate-supporting apparatus, a concave portion which includes a depression slanting from the peripheral portion to the center is provided, the semiconductor substrate is supported in a position where the peripheral portion of the back surface of the substrate contacts the slanting surface of the concave portion, and the concave portion is formed so that an interval between the center of the concave portion and the semiconductor substrate becomes the designated distance. The slanting surface of the concave portion may include a portion of a spherical surface or a conical surface.
