  • Publication number: 20220163169
    Abstract: A maintenance apparatus for a cryocooler includes a glovebox, a container, and a lid. The glovebox is configured to be joined to a cooling subject coupled to a cylinder of the cryocooler. The glovebox defines a first glovebox chamber that accommodates a cryocooler part excluding the cylinder. The cryocooler part includes a displacer of the cryocooler dismounted from the cylinder. The container is disposed in the first glovebox chamber and configured to accommodate the cryocooler part. The lid is disposed in the first glovebox chamber. The lid is configured to disconnect a cylinder chamber of the cylinder from the first glovebox chamber when the cooling subject is joined to the glovebox.

  • Patent number: 8685498
    Abstract: 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.

  • Patent number: 8408503
    Abstract: A stage apparatus enables easy position alignment at a real installation site. Mounts 25 having sub base plates 21 arranged thereon are provided on carriages 25 and thereby constitute sub mounting tables 20a to 20d; and the mounts 25 are fixed to a main mounting table 10 having a main base plate 11. The positions of main base plate 11 and sub base plates 21 are aligned with each other by adjustment mechanisms 30 provided on the sub mounting tables 20a to 20d. As main positioning members 16 and sub positioning members 241, 242 are arranged on the main mounting table 10 and sub mounting tables 20a to 20d, separation can be performed so that a state of position alignment is restorable. Accordingly, position alignment is easy when assembling after transportation.

  • Patent number: 8286318
    Abstract: 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.

  • Patent number: 8205952
    Abstract: 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 N1 to Nn by the coefficient values. When the respective voltages corresponding to the discharge positions are applied to piezoelectric elements inside a discharge head and a discharge liquid containing the spacers are discharged through the plural nozzles N1 to Nn provided in the discharge head, the spacers are placed on the object for discharging by numbers according to the random numbers.
