  • Publication number: 20120025647
    Abstract: Disclosed herein is a spindle motor. The spindle motor includes a rotor and a stator. The rotor includes a rotating shaft and a rotor casing which is provided with a magnet. The stator rotatably supports the rotor. The stator includes an armature facing the magnet. When the rotor casing rotates at a low speed, the rotating shaft rotates in a state of being inclined at a predetermined angle with respect to the vertical direction in which the rotating shaft is upright on the stator. Therefore, because the rotating shaft rotates in the state of being inclined with respect to the stator, the rotor can uniformly rotate. If the spindle motor is used in an optical disk apparatus for forming a label surface on an optical disk, the quality of the image on the label surface of the optical disk can be enhanced.

  • Publication number: 20110168333
    Abstract: A method for manufacturing light emitting devices is provided. The method may reduce the inner pressure of a laminated image emitting device panel, thereby preventing failure of the panel. The method includes holding a first substrate with a lower chuck located in a vacuum chamber; holding a second substrate with an upper chuck located opposite the first chuck in the vacuum chamber; creating a high vacuum in the vacuum chamber; correcting positions of the first substrate and the second substrate; supplying gas having a temperature of about 50 to about 200° C. into the vacuum chamber; temporarily laminating the first substrate and the second substrate; venting the vacuum chamber; and bonding the first substrate and the second substrate. The panel is laminated after being filled with a heated gas and thus, when it is exposed to room temperature, the mobility of the gas decreases while reducing its initial inner pressure, thereby preventing panel failure.
