摘要:
Actuator independently dedicated to nozzles divided into a plurality of groups are fixed to a common flow path unit having the nozzles formed therein with through holes aligned with one another. Heads of various types can be formed by using the actuator units of the same design only by changing the mode of arrangement of the nozzles in accordance with the purpose.
摘要:
An ink jet print head is disclosed which includes an ink nozzle member with nozzles, an ink pump member disposed on the ink nozzle member and having ink chambers formed behind the respective nozzles, and piezoelectric/electrostrictive elements each disposed on a wall defining the corresponding ink chamber, for deforming the wall to change a pressure of the ink chamber, whereby the ink in the ink chamber is jetted through the corresponding nozzle. The ink pump member consists of a spacer plate having windows which are closed by a closure plate and a connecting plate disposed on the spacer plate, so as to give the respective ink chambers. The connecting plate has communication holes through which the ink chambers communicate with the nozzles. The spacer plate, closure plate and connecting plate are formed from respective ceramic green sheets, which are laminated on each other and fired into an integral ceramic structure as the ink pump member. The piezoelectric/electrostrictive element includes a pair of electrodes and a piezoelectric/electrostrictive layer, which are formed by a film-forming method on an outer surface of the closure plate.

A method of manufacturing an ink jet head including the steps of: laminating a dry film photoresist 51 on an inner surface of a nozzle plate 2, the dry film photoresist being a photohardening resin; exposing the photoresist 51 with such energy as to half-harden the photoresist while superposing thereon a photomask M1 having a predetermined masking pattern; developing the thus exposed photoresist 51; laminating a photoresist 52; secondarily exposing the photoresists 51, 52 to form a partially hardened portion 5C; bonding an elastic plate on the portion 5C; and integrating the bonded plates while hardening them by heating.
摘要:
An image recording apparatus forms an image on a recording medium including a liquid accommodation layer by landing a liquid to the liquid accommodation layer of the recording medium. The image recording apparatus includes a first unit that performs pre-processing of landing the liquid containing a material with absorbability lower than that of the liquid accommodation layer to an edge of an image formation region at which the image is scheduled to be formed; and a second unit that forms the image at the image formation region of the recording medium after the first unit performs the pre-processing.

摘要:
A pressurizing chamber 1 is formed as a recess by half etching of a silicon single-crystal substrate 2. A nozzle communicating hole 6 through which the pressurizing chamber 1 is connected to a nozzle opening 5 is formed as a through hole which is smaller in width than the pressurizing chamber 1. The pressurizing chamber 1 is connected to the nozzle opening 5 in the other face via the nozzle communicating hole 6 while reducing the volume of the pressurizing chamber 1 to a degree as small as possible. The silicon single-crystal substrate is used as a member constituting a spacer so that an ink drop of a reduced ink amount suitable for high density printing flies with high positioning accuracy.
摘要:
An image recording device which includes a control unit which alternately performs, main-scannings in which the recording head is moved in the main-scanning direction while the recording head ejecting the liquid to form line images that extend in the main scanning direction and are adjacent to each other in the sub-scanning direction, and sub-scannings in which the recording head is moved in the sub-scanning direction, and a detection unit which detects a displacement of a mark which is formed on the recording medium in the sub-scanning direction, wherein the control unit adjusts a movement amount of the recording head which is moved in the sub-scanning direction in the sub-scannings on the basis of a detection result of the detection unit.
