Abstract:
A polishing pad for use in chemically mechanically polishing a semiconductor substrate enhances the uniformity of the rate at which material is removed from the surface of the semiconductor substrate, thereby ensuring the reproducibility of the chemical mechanical polishing process. The polishing pad has main grooves that divide an upper portion of the pad into a plurality of cells. At least one of the cells includes a land portion and a grooved portion substantially enclosed by the land portion. A respective slurry hole extends through the pad to the grooved portion such that slurry supplied through the slurry hole feeds into the grooved portion but is impeded by the land portion from flowing outwardly of the cell.
Abstract:
A method of controlling starting current of an adaptive spindle motor in consideration of maximum allowable consumption power and a disk drive using the method. The method includes measuring a supply voltage supplied to the disk drive, calculating a maximum current that can be supplied to the spindle motor in a range of maximum allowable power in correspondence to the supply voltage measured in the measuring of the supply voltage, and applying the calculated maximum current to the spindle motor to start the spindle motor.

In an equation F=Rdo/(Sd H 1.767), F>21, Tc/CFT≦1.35, and Rdi>(Ryi or Rxi) are satisfied, wherein Sd is a length of a diagonal effective picture of the panel, Rdo is a curvature radius of a diagonal outer surface, Ryo is a curvature radius of a vertical outer surface, Rxi, Ryi and Rdi are a horizontal, vertically and diagonal curvature radius, respectively, CFT is a thickness of a center portion, Tc is a thickness of a diagonal end of the effective surface, F is a planarizing rate of the outer curvature.
Abstract:
The present invention relates to an anti-jerk control apparatus and method for an Hybrid Electric Vehicle (HEV).The anti-jerk control apparatus includes a model speed calculation unit for calculating a model speed of the motor in a state in which a vibration of a drive shaft is not considered. A vibration occurrence determination unit detects a speed vibration component while calculating a reference speed difference and an average speed difference from differences between the model speed and an actual speed of the motor, thus determining whether a vibration occurs on the drive shaft. A torque correction value calculation unit calculates a motor torque correction value for anti-jerk required to damp the vibration of the drive shaft, and controls torque of the motor if the vibration occurrence determination unit determines that the vibration occurs on the drive shaft.
Abstract:
A cooking apparatus is provided. The cooking apparatus includes a cooking cavity, an upper space formed above the cooking cavity, lateral side spaces formed to at opposite lateral sides of the cooking cavity, a rear space formed behind the cooking cavity, and a lower space formed below the cooking cavity. A fan provided in the rear space generates a cooling flow that cools components housed in the rear space. A cooling flow path extends from the rear space and into the upper space and lateral side spaces. Flow from the upper space enters the door to cool the door and is exhausted through a lower portion of the door. Flow from the lateral side spaces, which includes an exhaust flow from the cooking cavity, is guided to the lower space and exhausted. In this manner, the cooking apparatus can be completely cooled and cooking odors and heat appropriately exhausted by the cooling fan positioned in the rear space.
Abstract:
An apparatus for preventing rotation of a seat frame for a vehicle having the seat frame that includes an inner link portion and an outer link portion that may be provided with a height adjustment device to adjust a height of a seat and a rack gear link may include a height link, wherein one end portion of the height link may be pivotally connected to a set bracket and the other end portion thereof may be pivotally connected to a cushion side member, and a rotation prevention link provided on the inner link portion wherein one end portion of the rotation prevention link may be pivotally hinged to the height link and the other end portion thereof may be movably installed on the set bracket.
Abstract:
A fold-and-dive apparatus for a vehicle seat is provided, which includes a protrusion projecting from a seat back that is folded toward a seat cushion, a moving block moving on a connection link by the protrusion when the seat back is folded, a lock plate connected to the moving block by a cable to move upward and downward on the connection link so as to restrain and release the seat cushion, and an elastic member having both end portions installed in the seat cushion and a vehicle body, respectively, to make the seat cushion slide forward. Since the seat cushion slides forward when the seat back is folded, the overlap of bolster portions between the seat back and the seat cushion is minimized, and thus the evenness of the seat back that is folded toward the seat cushion and the luggage trim is maximally improved.
Abstract:
A seat latch structure is provided, which includes a base bracket mounted on a seat for a vehicle and having a first insertion hole and a second insertion hole formed thereon and an opening which is formed on one side thereof and into which a striker fixed to a vehicle body is inserted, a claw having a first through-hole formed thereon to correspond to the first insertion hole and a locking groove formed on one side thereof, a pawl provided on one side of the claw and having a second through-hole formed thereon to correspond to the second insertion hole, a first rotating shaft and a second rotating shaft inserted into the first through-hole of the claw and the second through-hole of the pawl, respectively, and a double torsion spring connecting the first through-hole and the second through-hole into which the first rotating shaft and the second rotating shaft are inserted, respectively. According to the seat latch structure, the noise generated during the operation of the seat latch is reduced and the operating force is increased to improve the merchantability.
Abstract:
Disclosed are an embroidery fabric clamping unit for use with an embroidery machine, and an embroidery machine comprising the same, which allow the embroidering of even embroidery fabrics of arbitrary shape. The embroidery fabric clamping unit comprises: a unit body having a joining part provided for attachment to and detachment from a work table of the embroidery machine; an embroidery fabric support table which is linked to the unit body and supports the embroidery fabric to be embroidered by the embroidery machine; a lever which is supported on the unit body, with the embroidery fabric placed in between, and is able to apply pressure to and release pressure from the embroidery fabric support table; and a lever driving part for driving the lever.
Abstract:
An image drawing method and apparatus using an off-screen buffer are disclosed. The method includes: creating an off-screen buffer including a first region and a second region; drawing a fixed image of images to be displayed on the first region; copying the first region on which the fixed image is drawn to the second region; drawing a moving image of the images to be displayed on the second region; and copying the second region on which the moving image is drawn to a frame buffer.
