  • Patent number: 8298852
    Abstract: A thin film type solar cell and a method for manufacturing the same is disclosed, which is capable of providing a wide light-transmission area without lowering cell efficiency and increasing processing time, so that the solar cell can be used as a substitute for a glass window in a building. The thin film type solar cell generally comprises a substrate; a plurality of front electrodes at fixed intervals on the substrate; a plurality of semiconductor layers at fixed intervals with a contact portion or separating channel interposed in-between, the plurality of semiconductor layers on the plurality of front electrodes; and a plurality of rear electrodes at fixed intervals by the each separating channel interposed in-between, the each rear electrode being electrically connected with the each front electrode; wherein the each rear electrode is patterned in such a way that a light-transmitting portion is included in a predetermined portion of the rear electrode.

  • Patent number: 6373178
    Abstract: Electron gun for a color CRT having main lens forming electrodes wherein a depth from a rim portion of an anode to an electrostatic field control electrode is deeper than the depth from the rim portion of a cathode to the electrostatic field control electrode, and a DQ lens action of a center beam portion formed by the DQ lens unit being weaker than the DQ lens action of an outer electron beam portion, whereby reducing a spot diameter by enlarging a main lens diameter and correcting inconsistency between a center beam and an outer beam in the DQ lens.

  • Patent number: 5869925
    Abstract: A Focusing electrode in an electron gun for a color cathode ray tube provides a higher degree of freedom in electron gun design and reduces errors during assembly of the electron gun. A first focusing electrode that receives a constant voltage has vertically elongated electron beam pass-through holes formed in it. A second focusing electrode that receives a dynamic voltage has electron beam pass-through holes that include a pair of burring parts formed on their upper and lower edges. The burring parts are disposed in each of the vertically elongated electron beam pass-through holes in the first focusing electrode without changing a horizontal diameter of the electron beam pass-through holes in the first focusing electrode.

  • Patent number: 5841224
    Abstract: An electron gun for a large-sized color cathode ray tube has three cathodes heated by a heater for emitting thermoelectrons, a first grid for controlling emitted electron beams on one side of the cathodes, a second grid for attracting the thermoelectrons gathered on the cathodes on one side of the first grid, a plurality of electrodes sequentially arranged on the second grid for accelerating and focusing the incoming electron beams, and a bead glass for fixing the electrodes spaced apart by predetermined distances, in which the thickness of the second grid is varied to decrease the divergence angle of the electron beams, and horizontal slits being rotary asymmetrical portions are formed in both sides around electron beam passing holes to contrive a quadrupole effect, thereby compensating for distortion of the electron beams on the periphery of a screen caused by a deflection aberration to thus improve resolution of large-sized Brawn tubes.

  • Patent number: 5574331
    Abstract: An in-line electron gun for a color picture tube has an accelerating electrode portion separated into two or three electrodes in a triode, in which a voltage supplied to respective electrodes is varied and an asymmetrical hole is formed in at least one among the electrodes to form an additional asymmetric lens, thereby preventing degradation of a focus characteristic caused by an abrupt increase of a diverging angle of electron beam in a high current region, degradation in the vertical electron beam due to an influence of a magnetic field of a deflection yoke, change of focusing force induced by voltage variation of a first accelerating/focusing electrode, and degradation of the electron beam owing to collision/repulsion among electrons in the electron beam.
