  • Publication number: 20060236927
    Abstract: A system and method for reliably cleaning the nozzle face of each head while flexibly coping with changes in specification for a product to be manufactured. The film forming apparatus has a plurality of heads for jetting droplets, each having an nozzle in a nozzle face; and a common head cleaning mechanism for collectively cleaning the nozzle faces, so that the head cleaning mechanism is not substantially affected by a change in the pitch between the heads, or the like. Typically, the head cleaning mechanism has a wiping sheet for wiping the nozzle faces; a supply unit for feeding the wiping sheet towards the nozzle faces; and a roller for pressing the wiping sheet against the nozzle faces while the wiping sheet is fed from the supply unit, so that an unused cleaning face can always be supplied to each nozzle face.

  • Patent number: 7088349
    Abstract: A method of sub-field drive can display with a mode of placing emphasis on responsiveness and display with a mode of placing emphasis on gray-scale reproductiveness. A field is divided into plural sub-fields on a time axis, and each of such sub-fields is a control unit of driving a pixel. A code storing ROM stores a code that controls sub-fields to collecting on-voltage intensively in a former part of a field based on display data. Another code storing ROM stores a code that controls sub-fields to increase levels of gray scale based on display data. A data encoder determines whether each pixel of display data is an edge part of a moving image or not, selects a code that enables superior display in responsiveness at the edge part of a moving and selects a code that enables superior display in gray scale reproductiveness in other parts from the ROMs.

  • Patent number: 6943765
    Abstract: Correction tables store correction data. Based on the correction data, a linear interpolation circuit generates data in accordance with a data value of input image data. A latch circuit group latches each piece of output data of the linear interpolation circuit in synchronization with a rising edge of a block signal. A selector selects correction data based on an address signal and outputs the correction data to an adder circuit. The adder circuit adds delayed image data to the selected correction data, thus generating corrected image data. Accordingly, an error among channels, which is caused by phase expansion, can be corrected.

  • Patent number: 6561611
    Abstract: Recording paper fed from a paper feed section comes in contact with a paper detection member of a detector unit and the paper detection member is rotated about a first fulcrum, shading the optical axis of an optical sensor. When the recording paper passes through and the paper detection member is brought out of contact with the recording paper, the paper detection member is restored to the former position and does not shade the optical axis. A carriage/cartridge detection member of the detector unit comes in contact with a carriage engagement part and a cartridge engagement part placed in a carriage and is rotated about a second fulcrum, shading the optical axis of the optical sensor. When the carriage/cartridge detection member is brought out of contact with the engagement parts, the carriage/cartridge detection member is restored to the former position and does not shade the optical axis.
