  • Patent number: 8454131
    Abstract: An ink jet print head is provided which, during a suction-based recovery operation, can effectively remove air bubbles from the common ink path by producing an ink flow in the common ink path. In each of a plurality of bubble forming chambers where an element is installed to generate a thermal energy, there are provided a first ink path for leading ink directly from the ink supply port and a second ink path for leading ink from the common ink path formed on a far side of the array of the bubble forming chambers with respect to the ink supply port. The plurality of the first ink paths include those ink paths with less flow resistance than that of the second ink paths and those ink paths with higher flow resistance than that of the second ink paths.

  • Patent number: 8328944
    Abstract: A vacuum evaporation apparatus includes an evaporation source, a combined conveyance body in which a glass substrate is superposed and aligned on a shadow mask fixed to a holding member, and a weight plate placed on the glass substrate presses the glass substrate to the shadow mask by gravity for holding the glass substrate, and a convey mechanism for conveying the combined conveyance body. The weight plate includes a shock absorbing member for absorbing an impact applied to the combined conveyance body in an in-plane direction of the glass substrate. The shock absorbing member includes a sliding body connected to the weight plate via a spring and having multiple recesses formed in a surface of the sliding body facing the glass substrate, and includes slide balls disposed in the multiple recesses.

  • Publication number: 20100212596
    Abstract: Provided is a weight plate of a vacuum evaporation apparatus, and a vacuum evaporation apparatus, which may prevent occurrence of displacement due to an impact or the like during a conveyance by a convey mechanism after a shadow mask and a glass substrate are superposed and aligned. The glass substrate is superposed and aligned on a top surface of a tension mask as the shadow mask fixed to a mask holding member. Then, the weight plate is placed on the glass substrate and presses the glass substrate by gravity to form a combined conveyance body. A liquid metal is filled in a hollow part of the weight plate at a filling factor of from more than 25% to less than 85% or other shock absorbing mechanism is provided for absorbing an impact applied to the combined conveyance body.

  • Publication number: 20100080915
    Abstract: When a position of a film formation mask is recognized by irradiating the film formation mask with light, an image having a high contrast cannot be obtained, which unstabilizes reproducibility of measurement accuracy for an alignment mark position, leading to an alignment error between a substrate and a mask. Provided is a film formation mask including a mask sheet having a positioning opening and a mask frame, in which a reflective member having a reflectance higher than that of the mask sheet is provided to the positioning opening. When light is irradiated onto the positioning opening of the film formation mask, an intensity difference between light reflected by the mask sheet and light reflected by the reflective member becomes stable. Therefore, the position of the film formation mask may be determined with high reproducibility.

  • Publication number: 20100024733
    Abstract: Provided are a film formation apparatus and a film formation method which are capable of forming a pixel pattern with good dimensional accuracy and with reduced misalignment in a plane direction between a substrate and a mask when the substrate is pressed against the mask. The film formation apparatus includes an alignment mechanism for aligning a substrate and a mask with each other and a pressing mechanism for pressing the substrate against the mask with a contact member provided to one end of a pressing body, which are provided in a vacuum chamber. After alignment between the substrate and the mask by the alignment mechanism, the contact member of the pressing body is brought into contact with a surface of the substrate, which is on a side opposite to the mask, to press the substrate.
