  • Patent number: 11967862
    Abstract: In a driving system, first and second inverters are connected to a driving motor, one end of a stator winding through which 3-phase current flows is connected to an output line of the first inverter, and the other end of the stator winding is connected to an output line of the second inverter. A winding pattern of the driving motor includes: coils wound in slots defined in the stator and to which 3-phase current is applied; coils wound on innermost and outermost sides based on a direction toward a rotating shaft of the driving motor in the slots, and being energized by different AC phases; and coils disposed between a first coil located on the outermost side and a second coil located on the innermost side, and being energized by the same AC phases as those of the first and second coils.

  • Patent number: 7868583
    Abstract: An apparatus and method for controlling battery discharging in a portable terminal having a detachable external battery are provided. The method includes determining if the external battery has been connected with the portable terminal when the portable terminal is booted, receiving power from the external battery when the external battery is connected with the portable terminal and receiving power from an embedded battery of the portable terminal when the external battery has been completely discharged. Furthermore, in charging the batteries, the embedded battery of the portable terminal is first charged when battery charging current is input in a state that the external battery has been connected with the portable terminal, and the external battery is charged when the embedded battery has been completely charged. Power from the external battery is first used when a portable terminal assembled with the external battery is used, and an embedded battery is first charged in charging batteries.

  • Publication number: 20060129898
    Abstract: A method is provided for accessing a media file divided and stored in a plurality of data sectors, and processing a bad sector in a mobile communication terminal having a hard disk drive. The method includes generating an access request event for the media file; designating an address of a first data sector to be accessed, as an access index for indicating an address to be accessed; attempting to access the data sector positioned at the access index for a predetermined time, and reading media data from an access-success data sector when access succeeds and writing predetermined default data into an access-failure data sector when the access fails; and determining whether a next data sector to be accessed exists, and when it is determined that the next data sector to be accessed exists, increasing the access indexing by 1 and accessing a data sector positioned at the increased access index.

  • Patent number: 5930549
    Abstract: A developing device for a semiconductor device fabrication accomplishes complete removal of by-products formed during development of a photoresist, by inverting the wafer over a container of developer and dipping the pattern-forming face into the developer. While the wafer is still inverted over the container, the pattern-forming face is sprayed with a rinse and the wafer is spun to remove the rinse and by-products. The device includes the container provided on a table and supplied with developer, a spin chuck using vacuum suctioning the face of the wafer opposite to the pattern-forming face, a driving motor for rotating the spin chuck, a vertical driver for moving the wafer into and out of the container, and an inverting driver for rotating the spin chuck and the vertical driver so as to selectively turn the pattern-forming face of the wafer to look upward or downward.

  • Patent number: 5899690
    Abstract: An apparatus for thermal processing of semiconductor wafers includes a table having in lateral sequence a heating chamber, a holding chamber, and a cassette stage and a boat for holding the wafers being processed. The apparatus further includes a boat transfer part for moving the boat between the holding chamber and the heating chamber, a wafer charging part for transferring the wafers loaded in a cassette on the cassette stage to the boat while it is in the holding chamber, and a wafer discharging part for transferring the wafers loaded in the boat back to the cassette on the cassette stage.

  • Patent number: 5872365
    Abstract: A UV irradiation apparatus, which includes a UV lamp installed in a chamber for generating UV rays; a vacuum chuck installed below the UV lamp for supporting and moving a wafer; and, a reflector surrounding the UV lamp for concentrating UV rays on the vacuum chuck. The apparatus further includes heating blocks for controlling the temperature at both sides of the vacuum chuck. Thus, it is possible to maintain an essentially constant temperature around the wafer supported by the vacuum chuck. As a result of the temperature control, when a protection tape attached to the front side of the wafer is irradiated with UV rays, an adhesive of the protective tape can be effectively degraded by a chemically reaction under optimum conditions, to thereby easily detach the protection tape from the wafer.

  • Patent number: 5803700
    Abstract: A device for mounting and dismounting a heavy weight includes a vertical frame having an opening formed on a side thereof, through which a heavy weight is received into the frame. A laterally extending frame is formed at a lower part of the vertical frame. A stopping member is attached to the lateral frame, opposite to the opening, to prevent the heavy weight from being moved outside the frame. A moving device moves the heavy weight to the frame and a lifter raises and lowers the heavy weight in the frame.
