    摘要: Modular partial bars include a substrate bar having a length and a plurality of printhead subunits attached to only one side of the substrate bar, each printhead subunit being spaced from an adjacent printhead subunit. These modular partial bars are used as building blocks to form full width staggered array printheads. When the printhead subunits are arranged on each substrate bar so that two substrate bars are capable of forming a full width staggered array printhead, each modular partial bar is referred to as a modular half bar. One modular half bar can be stacked on another modular half bar any number of ways. For example, two half bars can be stacked with their printhead subunit containing sides facing the same direction, away from one another or towards one another. When two half bars are stacked with their printhead subunit containing sides facing in the same direction, an ink manifold for supplying ink to the printhead subunits of the lower half bar can be provided in the substrate of the upper half bar. When half bars are arranged with their printhead subunit containing sides facing each other, a common ink supply manifold can be used to supply ink to all of the printhead subunits in the full width staggered array, thus eliminating the need for two separate ink supply manifolds. By modifying the construction of the channel plates typically used to form the printhead subunits, the need for a separate ink supply manifold can be entirely eliminated.

    摘要: The new heater element design has a pit layer which protects the overglaze passivation layer, PSG step region, portions of the Ta layer and dielectric isolation layer and junctions or regions susceptible to the cavitational pressures. Further, the inner walls of the pit layer define the effective heater area and the dopant lines define the actual heater area. In alternative embodiments, the dopant lines define the actual and effective heater areas, and an inner wall and a dopant line define the actual and effective heater areas. Further, when the new heater element designs are incorporated into printheads having full pit channel geometry and open pit channel geometry, the operating lifetime of the printhead is extended because the added protection of the pit layer prevents: 1) passivation damage and cavitational damages of the heater elements; and 2) degradation of heater robustness, hot spot formations and heater failures well into the 109 pulse range. The printhead incorporating the new heater element design can be incorporated into drop-on-demand printing systems of a carriage type or a full width type.

    摘要: A method and apparatus actuates a line of printing elements to form characters on a recording medium contained on a curved surface of a platen. The printing elements are sequentially actuated, starting with nozzles located furthest from the platen and proceeding towards printing elements located closest to the platen until the actuation of all element has been performed. The line of printing elements can form a printhead which includes a plurality of nozzles arranged in at least one line having opposing ends, this line being substantially perpendicular to a longitudinal axis of the curved platen. Preferably, the line of nozzles is arranged with its center located closest to the platen and the nozzles are actuated starting at the ends of the line of nozzles.

    摘要: Operating an ultrasonic transmitter and receiver includes providing a MEMS composite transducer. The MEMS composite transducer includes a substrate. Portions of the substrate define an outer boundary of a cavity. A first MEMS transducing member includes a first size. A first portion of the first MEMS transducing member is anchored to the substrate. A second portion of the first MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. A second MEMS transducing member includes a second size smaller than the first size of the first MEMS transducing member. A first portion of the second MEMS transducing member is anchored to the substrate. A second portion of the second MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. A compliant membrane is positioned in contact with the first and second MEMS transducing members. A first portion of the compliant membrane covers the first and second MEMS transducing members. A second portion of the compliant membrane is anchored to the substrate. Electrical pulses are sent to the first MEMS transducing member which causes the first MEMS transducing member and the compliant membrane to vibrate. The vibrations of the first MEMS transducing member and the compliant membrane are transmitted to an object. Echo signals are received from the object. The received echo signals are converted into electrical signals by the second MEMS transducing member.

    摘要: An internal filter includes a lower substrate and an upper substrate. Fluid passages are formed by etching grooves into the surface(s) of the upper and/or lower substrates, and/or in one or more intermediate layers. The filter pores extending between the fluid passages are formed by etching second grooves that fluidly connect the fluid passages. Two or more sets of the one or two intermediate layers can be implemented to provide additional filter passages and/or pores. Each set can be connected to a separate fluid source and/or a separate microfluidic device. In another internal filter, the inlet and outlet passages and the filter pores are formed on the same upper or lower substrate. The inlet and outlet passages are partially formed in a first step. In a second step, the inlet and outlet passages are completed at the same time that the filter pores are formed.
