  • Patent number: 8168001
    Abstract: Film-forming apparatus including a film-forming vacuum chamber having a stage for a substrate, a chamber for mixing gas comprising a raw gas and a reactive gas connected to the film-forming chamber, a chamber for vaporizing the raw material, and a gas head for introducing the mixed gas into the film-forming chamber, disposed on the upper face of the film-forming chamber and opposed to the stage. Particle traps with controllable temperatures are positioned between the vaporization chamber and the mixing chamber and on the downstream side of the mixing chamber. When forming a thin film with the apparatus, a reactive gas and/or a carrier gas are passed through the film-forming chamber while opening a valve in a by-pass line, connecting the primary side to the secondary side of the particle trap arranged at the downstream side of the mixing chamber. The valve is then closed and the film-forming operation is initiated.

  • Publication number: 20090066976
    Abstract: A printing apparatus free from contamination of dust into a coated layer is provided. A printing apparatus of this application includes a first ejecting head and a printing head. The first ejecting head is located on a leading side in a moving direction D of the printing head. Since electric charge is removed from an object to be printed and dust is removed therefrom, by blowing an electric charge-removing gas through the first ejecting head before an ink lands on the object to be printed, dust does not contaminate a coated layer. In addition, since a suction hole is arranged between an ejecting hole and a nozzle zone, a stream of the electric charge-removing gas is not formed in the nozzle zone, and thus a meniscus of nozzles is not disturbed.

  • Patent number: 7472987
    Abstract: According to a first invention, since a flow of a spacer dispersed liquid is formed in a transporting chamber separated from a discharging chamber by an internal filter, the spacer dispersed liquid is stably discharged through an ejection hole, while the discharging chamber on a side of a nozzle plate is not affected by the flow of the spacer dispersed liquid. According to a second invention, since a spacer dispersed liquid does not flow inside a discharging chamber in a printing state in which the spacer dispersed liquid is discharged, the spacer dispersed liquid is stably discharged through an ejection hole. To the contrary, since the spacer dispersed liquid is directed inside both the discharging chamber and the transporting chamber in a waiting state in which the spacer dispersed liquid is not discharged, spacer particles in the spacer dispersed liquid do not settle.
