Abstract:
A suction nozzle (20) attracts and holds signal wires (14) by suction and positions and fixes the wires (14) to desired positions on a circuit board. As a result, the nozzle (20) can attract the wire (14) and easily hold it even if the ends of the wires (14) are spatially scattered, e.g., if the wires are somewhat away from the nozzle (20). Since the signal wires (14) are attracted into and held by the nozzle (20) in such a way, no excessive force is applied to the wires (14) over the sucking force of the nozzle (20) and the wires (14) are not cut during transfer even when they are transferred in the holding state.

A computerized logic synthesizer. The synthesizer receives a functional logic design and simulates a logic circuit. A plurality of module generators provide various circuit alternatives. The system includes means for optimizing the design of the circuit. A topology graph illustrates critical paths through the circuit. Virtual instruments are used to simulate operation of the circuit.
Abstract:
A method of appending data to compressed data stored on tape (10) in the form of records (CRn) wherein compressed data is stored in groups (Gn) independently of the record structure of the data and each group has an associated data structure (4), containing information relating to the group contents in terms of entities (En), where an entity can contain more than one record, and means (H) for storing information on the number of records in each entity (En) characterised by locating the entity containing the last record to be retained and changing said stored information to indicate the number of wanted records in that entity and writing the data being appended to a subsequent new entity.
Abstract:
An object based computer system has viewers which may be directed around the object world of the system. Some objects are sequence objects. A sequence object has a path list associated with it and there is the facility to link a viewer to a sequence object and thereby allow it to follow a predetermined sequence of objects to be viewed.
Abstract:
A water-vapour permeable material comprising a perfluorocarbon polymer incorporating lithium sulphate groups covalently bonded to the carbon skeleton of the polymer, a method for producing said material and an apparatus for drying gas including tubing made of said material.
Abstract:
A broadband-tunable external fiber-cavity laser system (11) includes a laser diode (19), and a single-mode optical fiber (17) with an in-line fiber optic grating filter (25). The grating filter (25) includes a grating (25) with divergent ridges (29) so that the periodicity at an exposed evanescent field can be adjusted by translating the grating (25) transversely with respect to the fiber (17). The evanescent field of light transmitted along the fiber core (37) is accessed at a side-polished region (18). The laser (11) preferentially oscillates at the reflected wavelength, so that the laser output is tuned by moving the grating (25). The grating is manufactured by oblique exposure to a holographic wavefront, producing the divergent pattern.
Abstract:
New and improved thermal ink jet printhead and method of manufacture wherein a tape automated bond (TAB) flexible circuit (16) is sequentially thermosonically bonded in a one-by-one wire bonding process to aligned conductive traces on a thin film resistor substrate (10). These traces provide electrical current paths for a corresponding plurality of heater resistors on the substrate, and these resistors function to heat a corresponding plurality of ink reservoirs in a thermal ink jet printhead.
Abstract:
A liquid capping system (100; 160) for sealing the ink-ejecting nozzles (180) of an inkjet printhead (54, 56) during periods of printing inactivity uses a vicious, inkjet ink compatible, sealing liquid (158) that is applied to the printhead surface to seal the nozzles (180) and prevent the ink in the printhead (54, 56) from drying. An inkjet printing mechanism (20) houses the printhead (54, 56) and has a service station (101) that stores the sealing liquid (158). To selectively apply the sealing liquid (158) to the printhead (54, 56), the service station (101) has an applicator mechanism (150) including a dispenser member (154) and a sealing wiper (130, 132; 165) that transfers the sealing liquid (158) from the dispenser member (154) to the printhead (54, 56). The sealing wiper (130, 132; 165) may also clean the printhead face or be dedicated to only sealing the printhead (54, 56). A method is provided for sealing an inkjet printhead (54, 56) using a liquid capping system (100, 160), including the step of spitting the printhead to clear the sealing liquid (158) from the nozzle (180) before returning to printing.
Abstract:
An optical sensor module for identifying characteristics of printed ink jet images on printing media residing in a media plane. The module has a chassis and a connected illumination source and detector spaced apart from the media plane. An integral optical element is positioned between the image plane and the illumination source and detector. The optical element has a first portion having a first optical characteristic positioned on a first optical path between the illumination source and a selected region of the media plane, and a second portion having a second optical characteristic different from the first optical characteristic and positioned on a second optical path between the illumination source and the selected region. The optical element may include diffractive optics, fresnel lenses, and conventional lenses formed of transparent plastics to steer, focus and diffuse light onto the selected region and return it efficiently to the detector.
Abstract:
This disclosure provides an electroluminescent ("EL") display device having anode, cathode, insulator and organic EL layers. The anode and cathode layers sandwich the other two layers, an the insulator layer is patterned to selectively block flow of current through the EL layers, and thereby locally block generation of light. The patterned insulator layer allows a single panel to display multiple visual attributes, yet does not required electrode patterning. The patterned insulator can be fabricated using photoresist exposure and development procedures. The photoresist is laid on top of a commercially available substrate/electrode layered pair, and is developed to create an assembly that can be completed in a single vacuum deposition process. By etching a small region of the electrode from the commercially available layered pair, and by choosing a deposition frame that blocks deposition on a second, different small region, electrical terminals may be coupled to the panel with a reduced risk of an electrical short.
