    Abstract: PROBLEM TO BE SOLVED: To provide a device having a sealed actuator chamber and a vent connected to the actuator chamber.
    SOLUTION: The vent connects the chamber to exterior atmosphere surrounding the device so as to equalize the pressure in the chamber. The vent has a size and form to allow pressure equalization to occur outside a normal operation cycle of the chamber and controls the pressure to prevent undesirable deflection of a membrane in the chamber and ensure the suitable operation of the device.

    Abstract: PROBLEM TO BE SOLVED: To reduce deflection caused by etching. SOLUTION: Structure for a micro-device is fabricated by forming a first layer of sacrifical material, a layer of a structural material over the first sacrifical material layer, a second layer of sacrifical material over the structural material layer, and a protective layer over the second sacrifical material layer. A release etch is used to remove the first and second sacrifical material layers at substantially same rate. A structural feature is fabricated by forming a first layer of a first material, a layer of structural material over the first layer of the first material, at least one cut in the structural material layer, and a first layer of a sacrifical material different from the first material over the structural material layer such that an interface is created between the first layer of the sacrifical material and the first layer of the first material in at least one cut.

    Abstract: PROBLEM TO BE SOLVED: To provide an inkjet printing system that independently control the mass and speed of ink liquid drops ejected from an inkjet print head.
    SOLUTION: A taper angle 330 depends on relationships among an exit diameter 310, an inside diameter 315, and/or thickness 325. For example, when the thickness 325 is fixed, the taper angle 330 can get larger as the difference between the exit diameter 310 and the inside diameter 315 is increased. Likewise, when the thickness 325 is fixed, the taper angle 330 can get smaller as the difference between the exit diameter 310 and the inside diameter 315 is decreased. The different values of and adjustments among the exit diameter 310, the inside diameter 315, the thickness 325, and the taper angle 330 can dictate the mass and speed of ink liquid drops that exit the nozzle 305. Further, they can allow the mass and speed of liquid drops to be independently dictated by the exit diameter 310 and the taper angle 330, respectively.

    Abstract: PROBLEM TO BE SOLVED: To provide a capacitive electrostatic actuator or a silicon material actuator which has solved the problem that an minute electromechanical structure(MEMS) generates a electrode contact and causes damage to electrodes as a result of arc discharge after several thousands of cycles, the electrode contact is generated between the center area of an element supported to prevent contact and a certain position of the edge of thin film separated from the opposite electrode due to the sufficient deflection of a silicon thin film, and contact at the intermediate positions of these elements and subsequent arc discharge are generated in relation to an earlier deterioration and fault of a capacitor, thereby extremely shortening the operation life of the actuator. SOLUTION: The minute electromechanical type liquid exhausting apparatus is provided with an internal structure to insulate a conductor at the bottom surface of the upper part of a thin film, and an external structure to prevent contact between electrodes due to an excessive deflection of the thin film at a position isolated from the center area of the thin film of the bottom surface at the upper part of the thin film.
