  • Automatic bonding system for liquid crystal display device and automatic bonding method using the same
    Patent number: 9835883
    Abstract: Disclosed is an automatic bonding system for an LCD device. The automatic bonding system includes a bonding unit configured to perform a process of bonding a first substrate to a second substrate, a first substrate supply unit configured to include an inverting arm and supply the first substrate to the bonding unit, a second substrate supply unit configured to include an adhesive resin coating unit and supply the second substrate to the bonding unit, a pre-hardening unit configured to perform a process of pre-hardening an adhesive resin that adheres the first and second substrates, and a hardening unit configured to perform a process of hardening the adhesive resin that adheres the first and second substrates. A gap between the first and second substrates bonded to each other by the bonding unit is a bonding gap controlled by a gap variable control stage.

  • Composition for treating cancer containing n,n-dimethylphytosphingosine
    Publication number: 20050143346
    Abstract: A composition and a kit for treating cancer comprising N,N-dimethylphytosphingosine. The composition represses the activity of sphingosine kinase, and therefore, intercepts various mechanisms which sphingosine kinase induces. For example, the composition blocks the phosphorylation of ceramide and sphingosine, thereby maintaining high concentration of ceramide and sphingosine. The ceramide and sphingosine induce apoptosis in cancer cells. Therefore, the composition according to the present invention induces apoptosis in cancer cells and accordingly kills the cancer cells.
