  • Patent number: 10553811
    Abstract: A method of manufacturing an organic electroluminescence display panel includes forming pixel electrode layers in a matrix on a substrate. The method includes arranging column banks extending in a column direction above the substrate. The method includes applying ink containing organic light emitting material to gaps between the column banks so that the ink is continuous between ends of the column banks in the column direction. The method includes arranging the substrate and a rectifying plate facing each other, the rectifying plate having a uniform density of through holes, such that the rectifying plate is at a predefined distance from the column banks. The method includes exhausting gas from an environment including the substrate and the rectifying plate. The method further includes heating the substrate to dry the ink to form an organic functional layer. The method includes forming a counter electrode layer above the organic functional layer.

  • Publication number: 20190355939
    Abstract: An ink drying process includes exhausting gas from atmosphere surrounding a substrate and drying ink through placing the substrate in a predefined pressure or less to form organic functional layers. Exhausting of gas includes: reducing, during a first period, pressure of the atmosphere from standard atmospheric pressure to a first pressure higher than vapor pressure of solvent having the highest vapor pressure among solvents of the ink; and subsequently reducing, during a second period, the pressure of the atmosphere to a second pressure lower than vapor pressure of solvent having the lowest vapor pressure among the solvents. Where pressure of the atmosphere is 10x Pa (X indicating a real number), a change amount average of X per unit time has a greater absolute value during the second period than during the first period.

  • Patent number: 10398442
    Abstract: Providing a stent which can easily be indwelled in a blood vessel in a state such that a catheter can be projected toward an inside of aneurysm. The stent is a stent for use in medical treatment of an aneurysm (1) and includes a cylindrical stent body (10) provided on a peripheral wall and having a plurality of insertion portions (11) through each of which a catheter (7) is insertable and a plurality of valving elements (20) provided in the insertion portions (11) respectively. Each valving element (20) is opened when the catheter (7) is inserted through one of the insertion portions (11). Each valving element (20) is closed when the catheter (7) is pulled out of the insertion portion (11). This suppresses an outflow into a blood vessel of a coil (9) placed in the aneurysm (1).
