A refrigerator appliance is provided with features for securing a dispenser to a door of the appliance. The dispenser can include a top wall, a bottom wall and a back wall that define a dispenser recess. An insert includes at least one of the top wall, the bottom wall, and the back wall. The insert is mounted to a back of a front panel of the door. As a result, the dispenser can have a trim-less appearance on the front panel of the door.

A method of making a circuitized substrate for use in an electronic package wherein the substrate, e.g., ceramic, includes more than one conductive layer, e.g., copper, thereon separated by a suitable dielectric material, e.g., polyimide. Each layer includes its own conductive location(s) which are designed for being directly electrically connected, e.g. using solder, to respective contact sites on a semiconductor chip to form part of the final package. Significantly, the resulting package does not include interconnections between the conductive layers at the desired contact locations; these locations, as mentioned, instead being directly connected to the chip.

A refrigeration appliance with a water dispenser includes a refrigerated cabinet having a dispenser area, a cabinet water inlet in the refrigerated cabinet connectable to a premises water line, and a cold water storage tank in the refrigerated cabinet. The tank has a tank body, an inlet for admitting water into the tank body supplied via the cabinet water inlet, and an outlet for providing water via a dispensing conduit to a dispenser in the dispenser area. The inlet includes a venturi portion for creating a reduced pressure within the tank body via flow of water into the cold water storage tank. The reduced pressure is in communication with the dispensing conduit via the outlet so that, after dispensing operation is completed, water remaining in the dispensing conduit is drawn toward the tank body. The tank body may include an evacuation chamber open to atmosphere, and a float valve may be provided.

A refrigeration appliance with a hot water dispenser includes a refrigerated cabinet having a dispenser area an input device for a user to indicate and control desired dispensing functions. The input device may require the user to perform two actions to dispense hot water: a first action to indicate one or more desired hot water parameters and a second action to dispense the hot water. A controller may reduce current draw in the appliance when water is heated, or may employ an energy storage device for heating.

Apparatus and method for compensating for distortion of the substrate of a printed circuit workpiece that involves performing two tasks. First, a mask that carries functional circuit features and alignment features is positioned rotatably so that the mask alignment features, when projected onto a table that holds the printed circuit workpiece, will be on a line extending parallel to one of two orthogonal axes of the table. Second, the spacing of alignment features on the printed circuit workpiece is determined and this determination is a measure of the distortion of the printed circuit workpiece substrate. A lens through which the mask image is projected is moved to adjust the magnification of the image in accordance with the measured distortion of the substrate of the printed circuit workpiece.

A blind via structure, and associated laser ablation methods of formation, that includes a blind via within a photoimageable dielectric (PID) layer on a substrate, such that the sidewall of the blind via makes an obtuse angle with the blind end of the blind via. The obtuse-angled sidewall may be formed by executing two processes in sequence. In the first process, photoimaging of the PID layer, with selective exposure to ultraviolet light, results in one or more blind vias having acute-angled sidewalls. The photoimaging cross links the PID material that had been selectively exposed to ultraviolet light such that a subsequent developing step removes PID material not cross linked, or weakly cross linked, to simultaneously form multiple blind vias having different sized openings. In the second process, laser ablation is selectively employed to remove the acute-angled sidewalls from particular blind vias in a way that forms replacement obtuse-angled sidewalls in the laser-ablated blind vias. Alternatively, the first process involving photoimaging may be omitted such that the second step involving laser ablation forms the entire obtuse-angled blind via. The resultant blind via structure includes at least one blind via having an obtuse-angled sidewall, and optionally, at least one blind via having an acute-angled sidewall.

A multilayer circuit fabrication approach and circuitized substrate are presented wherein at least two conductive layers are formed over a substrate. The conductive layers are separated by a first dielectric layer and the structure is encapsulated with a second dielectric layer. The first dielectric layer includes open areas exposing a portion of the underlying support structure aligned to those areas where contact points are to reside in the second conductive layer. The first dielectric layer comprises a blanket dielectric layer such that recesses are defined in the upper surface thereof aligned to the open areas of the first conductive layer. The second conductive layer thus resides in two planes, both of which comprise planes other than a plane of the first conductive layer. A plurality of openings can be simultaneously formed to expose contact points in both the first and second conductive layers.

A refrigeration appliance with a hot water dispenser includes a refrigerated cabinet having a dispenser area, a cabinet water inlet in the refrigerated cabinet connectable to a premises water line, and a hot water storage tank. The tank has a tank body, a heater in the tank body, an inlet for admitting water into the tank body supplied via the cabinet water inlet, and an outlet for providing water via a dispensing conduit to a dispenser in the dispenser area. The inlet includes a venturi portion for creating a reduced pressure within the hot water storage tank via flow of water into the hot water storage tank. The reduced pressure communicates with the dispensing conduit via the outlet so that, after dispensing water remaining in the dispensing conduit is drawn toward the tank body. Refrigeration devices with premises line pressure water distribution systems are also disclosed.

摘要:
A photolithography imaging system and method that performs the tasks of mask alignment, panel recognition, establishing position offsets and adjusting mask rotation for accurate overlay imaging of the mask onto the panel, and correctly adjusting image magnification or reduction to properly size each stepped image to the panel distortion. This invention applies more directly to substrate panels whose dimensional stability is found difficult to control, repeatedly. More specifically, it applies to panels whose X axis distortion factor varies greatly from its Y axis distortion factor and the average adjustment of the image magnification or reduction does not satisfy tight registration requirements. What is new is that the calculation of the magnification or reduction adjustment is based on the mask image dimensions.
