Abstract: A method for manufacturing an ejection head (10) or ejector suitable for ejecting in the form of droplets (16) a liquid (14) conveyed inside the ejection head (10), comprising a step of producing, from a silicon wafer, a nozzle plate (12) having at least one ejection nozzle (13); a step of producing, from another silicon wafer, a substrate (11) having at least one actuator (15) for activating the ejection of the droplets of liquid through the nozzle (13); and a step of joining the nozzle plate (12) and the substrate (11) together to form the ejection head, wherein this joining step comprises the production of a junction (25), made by means of the anodic bonding technology, between the substrate (11) and the nozzle plate (12), in such a way that, in the area of this junction (25), the ejection head (10) does not present structural discontinuities, and also possesses a resistance to chemical corrosion by the liquid (14) contained in the ejection head (10) at least equal to that of the silicon constituting both the substrate (11) and the nozzle plate (12). The method of the invention may be applied for manufacturing an ink jet printhead (110), having one or more nozzles (113a, 113b, etc.), which has the advantage, with respect to the known printheads, of also being suitable for working with special inks characterized by high level chemical aggressiveness. In general, the ejection head of the invention, thanks to its structure which is globally highly robust and also chemically inert in the area of the junction (25), can be used advantageously with various types of liquids, even with marked chemical aggressiveness, in different sectors of the art, for example for ejecting paints on various types of media, generally not paper, in the industrial marking sector; or for ejecting in a controlled way droplets of fuel, such as petrol, in an internal combustion engine.

Abstract: On a die that has etchings on a surface, firstly a sheet of negative photoresist is laid down which, by means of an exposure and subsequent development, is left only above the etchings; then, upon the negative photoresist, a positive photoresist is applied, which is subjected to exposure and development to produce functional geometries deposited in thin film; subsequently the positive photoresist is removed in a “lift-off” operation, and the negative photoresist is taken off in a plasma operation, thus revealing the etchings.

Abstract: An optical transducer for determining the angular position of a rotating member relative to a fixed structure, comprises a notched disc 13 rotatable inside a support housing 12, a light emitter 18 and a plurality of photovoltaic cells 19 for detecting the passage of light through the disc notches. The active and passive elements of an electronic circuit connected to the photovoltaic cells are carried by a single ceramic plate 21, which also acts as a support for the cells 19. The circuit comprises trimming resistors in the form of films deposited on the ceramic plate and connected to the amplifiers by the photovoltaic cells. In order for the signals generated by the amplifiers to have constant, predetermined peak values, the values of the resistors are trimmed during the production stage by means of a laser which selectively burns away parts thereof. The ceramic plate 21 is cemented on to the transducer housing 12, which is then positioned on the laser apparatus. The operations involved in presetting the resistors is carried out with the transducer in operation, and the laser need only be focused and pre-positioned once for the entire circuit.
