Abstract:
A magnetic head follows a track in a hard disk drive as positioned by micro-actuator and voice coil motor. Embodiments operate two control paths. The micro-actuator control path generates a version of micro-actuator control signal stimulating the micro-actuator. The voice coil motor control path generates a version of voice coil control signal, amplified based upon tuning gain to stimulate voice coil motor. A decoupling feedback filter decouples these control paths, using the micro-actuator control signal version. Either control path may include a notch filter. A track following command, with PES removed, directs the micro-actuator control. The servo-controller may digitally support the invention, which may include the servo-controller program system. An implementation may be optimized within a hard disk drive, possibly as part of the manufacturing process. The hard disk drive is a product of that process.
Abstract:
There is provided a bracket for securing a side airbag for an automotive vehicle. The bracket fixes a path such that a connection strap connecting the side airbag to the bracket is secured to an A-pillar and removes any interference when the side airbag is assembled, to make it easy to assemble the side airbag in a manufacturing site. The bracket has a through aperture through which a bolt is fastened, and a mounting plate secures the side airbag to the vehicle. Protrusions are each formed on each of both side ends of the bracket, and a bracket clip is installed on the external surface of the bracket. The bracket clip comprises: a bending part formed in the middle of the bracket clip; a plurality of support plates formed at either side of the bending part; and through apertures formed on the support plates, corresponding to the through aperture of the bracket. In the present invention, the path of the connection strap connecting the side airbag to the bracket is fixed by the bracket, and there is no interference when the bracket is assembled to install the side airbag in the A-pillar. Therefore, the assembling efficiency is improved, time is save, and productivity is improved in the manufacturing site.

There is provided a bracket for securing a side airbag for an automotive vehicle. The bracket includes a bracket which connects a connection strap, connected to the side airbag, to a pillar of the vehicle, and wherein the bracket includes: an installation aperture to be secured to the pillar; and a fixing bracket aperture through which the connection strap connected to the side airbag passes, and wherein the fixing bracket aperture includes: a fixing bracket central aperture through which the connection strap passes; and extension apertures formed at both ends of the fixing bracket central aperture and each having a greater width than that of the fixing bracket central aperture.
Abstract:
A method of manufacturing a semiconductor device includes forming conductive structures on a substrate. Each of the conductive structures has a line shape that extends along a first direction parallel to the substrate. Insulating spacers are formed on upper sidewalls of the conductive structures. An insulating interlayer is formed that covers the conductive structures. A portion of the insulating interlayer between the conductive structures is etched to form a contact hole. An upper portion of the contact hole is larger than a lower portion thereof. The upper portion of the contact hole has a first width along the first direction and a second width along a second direction parallel to the substrate and substantially perpendicular to the first direction. The first width is substantially larger than the second width. The contact hole is filled with a conductive material to form a contact plug.
Abstract:
Disclosed herein are a noncontact single side probe and an apparatus and method for testing open and short circuits of pattern electrodes. By feeding power to one end of each of the pattern electrodes and sensing an electrical variation value using a noncontact type single side probe device including an exciter electrode and a sensor electrode as a single module, the open and short circuits of pattern electrodes can be tested by one scanning process. Since the open and short circuits of the pattern electrodes are tested using the noncontact type single side probe device, the pattern electrode can be prevented from being damaged due to a contact failure or pressurized contact and the life span of the probe device can increase compared with a contact type probe device.
Abstract:
A spin-on glass (SOG) composition and a method of forming a silicon oxide layer utilizing the SOG composition are disclosed. The method includes coating on a semiconductor substrate having a surface discontinuity, an SOG composition containing polysilazane having a compound of the formula —(SiH2NH)n— wherein n represents a positive integer, a weight average molecular weight within the range of about 3,300 to 3,700 to form a planar SOG layer. The SOG layer is converted to a silicon oxide layer with a planar surface by curing the SOG layer. Also disclosed is a semiconductor device made by the method.
Abstract:
An additive composition for a slurry contains a first salt of polymeric acid including a first polymeric acid having a first weight average molecular weight and a first base material, and a second salt of polymeric acid including a second polymeric acid having a second weight average molecular weight and a second base material. A slurry composition is prepared by mixing the additive composition, a polishing particle composition, and water. When implementing a chemical mechanical polishing using the slurry composition, a favorable polishing selectivity is realized.

Provided is a navigation system including method of setting a destination in a navigation terminal, which includes receiving a position information message; and setting position coordinates corresponding to position information included in the position information message as position coordinates of a destination related to a certain route.
Abstract:
There is provided a guide plate for a side air bag. The guide plate includes a fastening member fastened to an inner surface of a vehicle body, a support member bent from a lower end of the fastening member and extending toward a passenger space of a vehicle, and a retaining member extending from a surface of the fastening member toward the passenger space of the vehicle. As the guide plate prevents a side air bag tube from being deployed in an upward direction, force for deploying the side air bag tube is not spread but concentrated to allow the side air bag tube to be properly deployed by opening a head liner.
