The present invention relates to a CMOS compatible MEMS microphone, comprising: an SOI substrate, wherein a CMOS circuitry is accommodated on its silicon device layer; a microphone diaphragm formed with a part of the silicon device layer, wherein the microphone diaphragm is doped to become conductive; a microphone backplate including CMOS passivation layers with a metal layer sandwiched and a plurality of through holes, provided above the silicon device layer, wherein the plurality of through holes are formed in the portions thereof opposite to the microphone diaphragm, and the metal layer forms an electrode plate of the backplate; a plurality of dimples protruding from the lower surface of the microphone backplate opposite to the diaphragm; and an air gap, provided between the diaphragm and the microphone backplate, wherein a spacer forming a boundary of the air gap is provided outside of the diaphragm or on the edge of the diaphragm; wherein a back hole is formed to be open in substrate underneath the diaphragm so as to allow sound pass through, and the microphone diaphragm is used as an electrode plate to form a variable capacitive sensing element with the electrode plate of the microphone backplate.

A stator assembly for an electric motor includes a stator housing, an expandable flux ring inserted into the stator housing and a plurality of magnets on an inner surface of the flux ring. Overmold material is molded around the magnets in the flux ring, such as by injection molding. The pressure of the overmold material as it is being molded expands the flux ring pressing the flux ring into engagement with the stator housing. The overmold material secures the magnets to the flux ring and the flux ring to the housing. One of the flux ring and stator housing has a dimple that engages a hole in the other of the flux ring and stator housing to align the flux ring and stator housing. In an aspect, the overmold material is molded to form at least one of a commutator end or rear bearing support, front bearing support and fan baffle. In an aspect, the overmold material is molded to form a keying feature. The keying feature can be slots of different widths between magnetic poles of the stator assembly. In an aspect, the flux ring and housing are preformed as a unit by stamping them from blanks and rolling them together. In a variation, the flux ring blank is rolled first to form the flux ring and the housing blank rolled around the flux ring with the flux ring acting as a rolling arbor.

A magnetic head suspension assembly is fabricated with an integral piece which includes a load beam section, a flexure section, a rear mount section and a leaf spring section between the load beam and rear mount. A tongue extends from the load beam to the flexure and has a down-facing load dimple which contacts the non-air bearing surface of an attached air bearing slider. The flexure includes narrow thin legs adjacent to a cutout that delineates the load beam tongue. The head suspension is characterized by a high first bending mode frequency and low pitch and roll stiffness.

A head gimbal assembly includes a micro-actuator, a slider, and a suspension that supports the micro-actuator and the slider. The micro-actuator includes a metal frame including a top support to support the slider, a bottom support to connect to the suspension, and a pair of side arms that interconnect the top support and the bottom support. The top support includes a rotatable plate and connection arms that couple the rotatable plate to respective side arms. A PZT element is mounted to each of the side arms. Each PZT element is excitable to cause selective movement of the side arms. The suspension includes a load beam having a dimple that engages and supports the rotatable plate in use.

A HGA includes a load beam having a dimple formed thereon; a flexure including a suspension tongue and a support plate connected with the suspension tongue; and a slider having a leading edge and trailing edge opposite to the leading edge. The slider is mounted on the flexure such that the slider is supported by the dimple at the center of the slider. The leading edge is attached on the suspension tongue and trailing edge is attached on the support plate. A weight-balance structure is formed on the suspension tongue of the flexure to balance the weight of the HGA between a portion from the trailing edge to the slider center and another portion from the leading edge to the slider center. The invention also discloses various methods of manufacturing HGA with the balanced weight.

In a nuclear reactor fuel assembly structured to support at least one non-linear fuel rod, the nuclear reactor fuel assembly includes at least two support grids, a first support grid and a second support grid structured to support at least one fuel rod in a non-linear shape. Each support grid has a plurality of generally square cells and wherein the cells on the first support grid and the second support grid are generally vertically aligned. Each cell has a first side, a second side, a third side, and a fourth side. Each cell further has protrusions extending from each the cell sides, wherein the protrusions are selected from the group including a spring, a dimple or an extended dimple. A spring is always disposed opposite of a dimple or an extended dimple. The first support grid includes at least one cell having an extended dimple extending from at least one cell side. The second support grid includes at least one cell aligned with the first support grid at least one cell having an extended dimple, wherein the second support grid cell has an extended dimple extending from a cell side other than cell side having an extended dimple on the first support grid. Thus, the extended dimples cause the fuel rod to be deformed.

Method of forming depressions (e.g. dimples) in a sheet material to form a textured surface thereon involves pressing one or more tool tips into a metallic or non-metallic sheet material while the sheet material is supported by a support layer that is relatively softer (e.g. having a lower Young's modulus) than the sheet material so as to allow plastic deformation and reduce pile-up of raised displaced material of the sheet material at the edges of the depressions.

A Hard Disk Drive (HDD) includes a write-inhibit signal that is generated by a head-disk interaction sensor during a write process that is integrated with a suspension of the HDD when fly-height modulation of the slider is detected during a write process. The suspension load beam includes a dimple and a laminated flexure. The laminated flexure includes a surface that is adapted to receive a slider and a surface that is adapted to contact the dimple. The head-disk interaction sensor is fabricated as part of the laminations of the flexure. The head-disk interaction sensor can be an accelerometer that senses an acceleration of the flexure when the slider contacts the disk of the disk drive and / or a pressure sensor that senses a pressure between the flexure and the dimple when the slider contacts the disk. A write-inhibit circuit is responsive to the sensor signal by inhibiting the write process.

A HGA of the invention includes a slider, a load beam having a locating hole formed therein; a flexure to support the slider and connect with the load beam; a separate dimple element having a dimple to extend through the locating hole and support the flexure at a position corresponding to a center area of the slider. The invention also discloses a method for manufacturing the HGA and a disk drive unit with the HGA.
