20090066976 | PRINTING APPARATUS - 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. | 03-12-2009 |
20100031693 | REFRIDGERATING MACHINE - A refrigerating machine including: a cooling stage that cools a target object; a He condensation section onto which said object is mounted; a reservoir that communicates with said He condensation section, and is filled with He gas; and a heat transfer buffer member that is arranged between said cooling stage and said He condensation section, and is composed of a material having a thermal conductivity lower than that of said He condensation section. | 02-11-2010 |
20100066775 | SPACER PLACING METHOD - A technology for placing spacers free from the occurrence of streaks is provided. Random numbers are generated by a computer, and made in one-by-one association with discharge positions of an object for discharging every generation, and stored in a memory unit of the computer. Coefficient values are determined for the respective discharge positions based on the stored random numbers, and individual voltage values to be required for the respective discharge positions are calculated through the multiplication of voltages set for respective nozzle holes N | 03-18-2010 |
20100112230 | COATED FILM FORMING METHOD - A coated film with no observable streak is formed. The landing positions of a first discharge liquid discharged through a first printing head and the landing positions of a second discharge liquid discharged through a second printing head are disposed in a mixed manner in an area on a substrate where the first printing head and the second printing head overlap. Which discharge liquids are to be landed is determined according to random numbers. Since a coated film which is formed with the first and second discharge liquids in a mixed manner is disposed between a coated film formed with the first discharge liquids and a coated film formed with the second discharge liquids, a boundary is obscured and no streak appears. | 05-06-2010 |
20100146762 | STAGE APPARATUS ASSEMBLING METHOD - An assembling method that is high in assembly accuracy and easily performed at the actual installation site is provided. In this method, the sub base plates on the sub mounting tables are aligned with respect to a main base plate on a main mounting table at a temporary installation site, and the state thereof is maintained. Then, the main mounting table and the sub mounting tables are separated from each other to be transferred to the actual installation site, and the positioning state is restored at the actual installation site. Since a positional alignment can be performed at the temporary installation site, the work required at the actual installation site can be reduced. Furthermore, since a fine adjustment can be performed at the actual installation site, the accuracy in the positional alignment can be improved. | 06-17-2010 |
