Abstract: Particles are adhesively bond to a support such as a glass or metal strip by covering the support with a film of a sol-gel solution by immersing in a liquid containing an organometallic compound, such as an organic silicon compound. The film is allowed to gel and during gelling, mineral particles are projected against the coated support. The gelled film coated with particles is dried and unbonded particles are removed. The method is of particular application to adhesively bonding clay, carbonate and silica particles.

Abstract: A method is described for making colored backed film material using a polyvinyl fluoride (PVF) film having a first face and a second face opposite the first face. The method comprises the steps of coating the first face of the PVF film with an ink-receptive coating. A carrier is then statically laminated to the second face of the PVF film. Using a rotary web printing apparatus, an acrylic ink is then continuously applied onto the first face of the PVF film. After drying the ink, the PVF film is separated from the carrier and the colored PVF film is coated with a pressure-sensitive adhesive and provided with a release paper.

Three aluminum nitride Layers composing the upper substrate layer have interior peripheries arranged in a step fashion stepping down toward the center of the multilayered wiring substrate. The central part of the upper substrate layer is thinner than the periphery. The surfaces and inside of the upper substrate layer are provided with conductive layers. The capacitor layer is a laminated body of two high dielectric layers formed of aluminum nitride with titanium nitride added thereto for raising the specific dielectric constant.

Abstract: Forming a green multi-layer component with an embedded pattern of barrier material, which may be in the form of a positive pattern to form a recessed area or in the form of a negative pattern to form raised areas on the component. Peripheral channels are machined into the green laminate surface to outline each negative or positive pattern feature, the channels being cut deep and wide enough to contact and overlap the edges of the barrier material. The layer of barrier material and the overlying layer(s) of ceramic material are separated from the remainder of the component to produce a non-planar part having raised areas in the case of a negative pattern of barrier material or a part having recessed areas in the case of a positive pattern of barrier material. An apparatus and process to control the machining depth of cut using both AC and DC sensing techniques is disclosed.

Abstract: A method of producing a piezoelectric/electrostrictive actuator including preparing first, second and third ceramic green sheets, and laminating the green sheets to form an unfired ceramic body which is then fired. The first, second and third green sheets form spacer, closure, and connecting plates, respectively, the spacer plate having a plurality of windows. An outer surface of the connecting plate that is remote from the spacer plate is machined so as to have a maximum waviness of not larger than 50 .mu.m. Additionally, piezoelectric/electrostrictive elements are formed on an outer surface of the closure plate over respective pressure chambers defined by the windows in the spacer plate.

Abstract: An apparatus for splicing the leading label in a roll of labels to one of the last labels in a second roll. The second roll, depleted because the labels are applied to articles in an assembly line, has photosensitive device that registers this depletion as the second roll is consumed. The device initiates splicing the leading label to a label in the depleted roll. A controller also responds to the device by moving the dancer arm to a predetermined position in order to control the registration of the leading label with the last labels in the second roll. The controller also responds to a count of the labels that are in the web between the production line and the splice in order to identify the article to which the splice has been applied to eject that article from the production line.
