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 ink jet print head includes pressure chambers, nozzles, and ink channels in a one-to-one correspondence. A diaphragm forms a side of each pressure chamber. The ink channels are formed in a restrictor plate. Piezoelectric elements are attached to the diaphragm and to a piezoelectric element fixing plate, which supports the piezoelectric elements. A housing of the head is formed with a common ink channel for supplying ink to the ink channels and an internal space into which the piezoelectric elements and the piezoelectric element fixing plate are at least partially inserted. A cover is provided for covering the piezoelectric element fixing plate. The cover is connected to the housing and is provided with an internal space large enough to maintain a gap between the cover and the piezoelectric element fixing plate.

摘要： To adhere an actuator unit onto one surface of a diaphragm, a dipping plate is used to evenly cling an adhesive agent to tip ends of a plurality of actuators formed in the actuator unit. The dipping plate is formed with a plurality of grooves corresponding to the respective ones of the plurality of actuators. An adhesive agent is poured into the grooves to the same level and the actuators are dipped into the adhesive pond while maintaining a state in which an imaginary first line that connects the tip ends of said plurality of actuators is in parallel with an imaginary second line that connects borders between immersed and non-immersed portions of the plurality of actuators. The actuators are drawn from the adhesive ponds and adhered to one surface of the diaphragm. An ink channel unit is connected to the opposite surface of the diagram.

摘要： An ink jet recording head is capable of: preventing any of stagnation in ink flow, formation of vapor bubbles, cavitation, or like problems from occurring in the ink flow; realizing an excellent ink ejection operation, and thereby realizing a high quality gradation expression in recording; and, lessening a degree of a required accuracy both in dimension and in alignment of its components being stacked together. In a method for manufacturing the ink jet recording head provided with a pressure generating chamber, this chamber is constructed of a through-hole of a chamber plate and a pair of plates, between which plates the chamber plate is sandwiched. The processing step for forming this through-hole further comprises the sub-steps of: forming a first resist film and a second resist film on a first and a second surface of the chamber plate, respectively, wherein the resist films assume substantially a same shape, but are different in length from each other when measured in a direction parallel to a flow direction of ink; and, etching away both the first and the second surface of the chamber plate using the resist films as its masks so that the through-hole is formed in the chamber plate and serves as the pressure generating chamber.

摘要： Connection electrodes are formed to be located on the same plane as discrete internal electrodes, and to be exposed to the rear face while being insulated from the discrete internal electrodes. With the conductive relationship between the connection electrodes and common electrodes, the resistance of the common internal electrodes is reduced, and the size of the fixed area is also reduced accordingly.

摘要： A print head for an ink-jet printer has a nozzle member defining a plurality of ink channels arranged side-by-side and each terminating in a nozzle. A plurality of actuators are disposed on one side of the nozzle member and respectively face one of the ink channels for pressurizing the ink liquid therein, in order to expel ink droplets through the nozzles. A support for supporting the actuators on the side opposite to the ink channels is provided and a plurality of connecting portions mechanically connect the support to the nozzle member. At least one of the connecting portions is arranged between the actuators. The connecting portions are spaced apart from one another in a longitudinal direction of the ink channels and are formed, for example, by bars extending transversely to the ink channels.
