摘要:
A method and apparatus for automatically compensating for thermal conditioning of an ink jet print head are provided. The method and apparatus monitor the time during which the print head experiences various temperatures. The driving voltage supplied to the ink jet transducer is adjusted over time to compensate for thermal conditioning of the print head.

An optical connector comprises first and second mating coupling members. The first member has two conductive terminal portions for connection to a driver circuit for a light emitting element, and the second member has a conductive portion which contacts the two terminal portions when the first and second members are coupled together for establishing electrical connection between the terminal portions.

A drop emitting apparatus including a diaphragm layer disposed on a fluid channel layer, a roughened bonding region formed on a surface of the diaphragm layer, a thin film circuit having conformal raised contact regions disposed on the bonding region, and a plurality of electromechanical transducers adhesively attached to the raised contact regions and electrically connected to the conformal raised contact regions by asperity contacts formed between the conformal raised contact regions and the electromechanical transducers.
摘要:
A system and method of operation for a piezoelectric transducer is described which utilizes a mesa structure interposed between a piezoelectric material element and a chamber diaphragm. The system can be used as a sensor where a net motion to the diaphragm causes a net charge equal to the sum of the charges on each piezoelectric diaphragm. Alternatively, the system can be used as an actuator wherein an applied voltage causes movement of the piezoelectric transducer and the chamber diaphragm.

The present invention provides an ink jet print head capable of fast, efficient and consistent printing. Such ink jet print heads include an ink ejecting component which incorporates electropolished surfaces. Electropolishing techniques useful in the production of such ink ejecting components are also discussed.

An electrical interconnect has an adhesive layer in which is formed an array of apertures, the apertures being of non-circular shape. An electrical circuit apparatus has a first circuit having at least one electrical contact, a second circuit having at least one electrical contact aligned to the electrical contact of the first circuit, and a standoff structure between the first and second circuits having at least one aperture aligned to one electrical contact of the first and second circuits, the aperture being of a non-circular shape.
摘要:
Two circuit bearing substrates, such as a rigid electronic circuit board and a flexible circuit film, each having large arrays or multiple arrays of surface contact pads or traces, are mechanically and electrically joined without relocating the substrates during the bonding process by using a bonding apparatus with multiple working tools or bond shoes. The bonding apparatus includes a fixture for holding the circuit bearing substrates with a joining layer between them, and two or more independently operated heated bond shoes that compress different portions of the circuit bearing substrates with the joining layer, such as a layer of anisotropic conductive film.

A multi-layer standoff/mask structure including a standoff having a plurality of standoff openings and a mask having a plurality of mask openings aligned with the standoff openings.
摘要:
An inkjet external ink manifold is provided that allows for use of a jet stack that does not internally contain ink manifolds. The external ink manifold has a manifold body that includes one or more ink manifold chambers and includes ports arranged to connect the chambers to one or more ink reservoirs. The external ink manifold further includes an adhesive layer overlying and sealing the ink manifold chambers. The adhesive layer includes a plurality of ports arranged to connect the external ink manifold chambers to the jet stack.
