  • Patent number: 11940060
    Abstract: The present invention provides a seal ring structure, which comprises a seal ring member. The seal ring member includes a first ring opening on one side and a second ring opening on the other. A periphery of the first ring opening includes a plurality of leak grooves. When the seal ring member and the valve ball squeeze each other, the plurality of leak grooves can reduce the torque required to rotate the valve ball. A leak-groove length of the plurality of leak grooves is smaller than a seal-ring-member length of the seal ring member. The plurality of leak grooves do not penetrate the seal ring member for avoiding leakage of fluid.

  • Publication number: 20240099086
    Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

  • Publication number: 20120312470
    Abstract: The invention discloses a rigid panel adhesion method including a smearing step and a pressing step. The smearing step smears glue on a surface of a first rigid panel to form a glue layer. The glue layer has a single contact portion being in one-dimensional form of a dot or line. The glue layer has a coverage ratio of no less than 50% over the surface of the first rigid panel. The pressing step touches the contact portion of the glue layer with a second rigid panel, and slowly presses the first and second rigid panels together to discharge gases between the first and second rigid panels, thereby adhering the first and second rigid panels to each other.

  • Patent number: 6586174
    Abstract: The present invention relates to a bioactive molecule, herein referred to as the CD8+ suppressor molecule, that is produced by the CD8+ subset of human T-lymphocytes and suppresses type-1 human immunodeficiency virus (HIV-1) replication through inhibition of viral transcription. The invention relates to isolation of clonal CD8+ cells lines that produce the antiviral activity and the development of an assay system for detection of the antiviral activity. The clonal cell lines and the assay system, described herein, may be utilized to purify, characterize and clone the CD8+ suppressor molecule. The CD8+ suppressor molecule may have therapeutic applications for treatment of diseases associated with HIV-1 infection.
