| Zusammenfassung: | PURPOSE:To aim at reduction in a application failure to be caused by dripping, by enlarging the outer diameter of a drop of phosphor emulsion, exising in and around a screw clamping an application valve or a stepped part of another stepped application valve, and making an area, where the liquid sticks, larger in this way. CONSTITUTION:When an application valve 2 is closed, phosphor emulsion is collected in droplike in and around a screw or a stepped part 3 of a stepped application valve. The phosphor emulsion collected in this droplike form sets a diameter A of the screw or the stepped part 3 of the stepped application valve to a range of 0.4B |
