  • Patent number: 11945235
    Abstract: There is provided a printing apparatus which includes the following: A printhead including a plurality of nozzles that discharge ink to a print medium. A first detection unit that detects a distance between the printhead and a platen. An adjustment unit that adjusts the distance between the printhead and the platen. An acquisition unit that acquires difference information concerning a difference of a distance between the platen and each of the nozzle on an upstream side and the nozzle on a downstream side in a conveyance direction of the print medium. The adjustment unit adjusts the distance based on a detection result of the first detection unit and the difference information acquired by the acquisition unit.

  • Patent number: 11788181
    Abstract: A deposition mask apparatus including a frame, a supporter including a plurality of supporting members fixed to the frame, and a deposition mask fixed to the frame is provided. The plurality of supporting members include at least a first supporting member that is closest to an intermediate position between a third portion and a fourth portion of the frame and a second supporting member that is located closer to the third portion of the frame than the first supporting member. The first supporting member in a state of warping downward from the frame with a first warping amount supports the deposition mask from below. The second supporting member in a state of warping downward from the frame with a second warping amount that is smaller than the first warping amount supports the deposition mask from below.

  • Patent number: 11739412
    Abstract: A wall surface of an opening of a deposition mask includes a first wall surface that extends from a first end toward a second surface, a second wall surface that extends from a second end toward a first surface, and a connection at which the first wall surface is connected to the second wall surface. When the opening is viewed from the first surface side along a normal direction of the first surface, the first end of the opening includes a first portion that extends in a first direction and has a first dimension and a second portion that extends in a second direction intersecting the first direction and a second dimension shorter than the first dimension. The first wall surface includes a first wall surface section that extends from the first portion toward the connection and a second wall surface section that extends from the second portion toward the connection. A height of the first wall surface section is lower than a height of the second wall surface section.

  • Publication number: 20190238993
    Abstract: A sound generating device includes an armature having a fixing part facing a first direction and overlapped on an outer surface of a yoke, an extension part extending from the fixing part in a second direction opposite to the first direction, and a movable part bent from the extension part and extending in the first direction, inserted into a coil to oppose a magnet, and connected to an oscillator. The fixing part includes two opposing edge parts that are spot-welded to the outer surface of the yoke at two reference weld areas separated in a perpendicular direction that is perpendicular to the first and second directions. The two opposing edge parts of the fixing part and the outer surface of the yoke are spot-welded at at least one additional weld area at a position separated in the first direction from the reference weld areas.

  • Publication number: 20180317016
    Abstract: A magnetic-field-generating unit and a coil vibrates an armature. The armature drives a diaphragm. The armature is formed of a rolled metal plate made of Permalloy. A workpiece is cut out of an unannealed metal plate with a wire saw or by etching such that the long-side direction of the workpiece corresponds to a transverse direction that is orthogonal to the direction of rolling performed on the metal plate. The cut-out workpiece is bent and is then annealed. Through this process, the warp of the armature is minimized.
