摘要:
Disclosed are a method of making a dielectric on a metal foil, and a method of making a large area capacitor that includes a dielectric on a metal foil. A dielectric precursor layer and the base metal foil are prefired at a prefiring temperature in the range of 350 to 650° C. in a moist atmosphere that also comprises a reducing gas. The prefired dielectric precursor layer and base metal foil are subsequently fired at a firing temperature in the range of 700 to 1200° C. in an atmosphere having an oxygen partial pressure of less than about 10−6 atmospheres to produce a dielectric. The area of the capacitor made according to the disclosed method may be greater than 10 mm2, and subdivided to create a multiple individual capacitor units that may be embedded in printed wiring boards. The dielectric is typically comprised of crystalline barium titanate or crystalline barium strontium titanate.

Disclosed are methods of making a dielectric on a metal foil, and a method of making a large area capacitor that includes a dielectric on a metal foil. A first dielectric layer is formed over the metal foil by physical vapor deposition, and a dielectric precursor layer is formed over the first dielectric layer by chemical solution deposition. The metal foil, first dielectric layer and dielectric precursor layer are prefired at a prefiring temperature in the range of 350 to 650° C. The prefired dielectric precursor layer, the first dielectric layer and the base metal foil are subsequently fired at a firing temperature in the range of 700 to 1200° C.

An extendable and adjustable insect entrapment apparatus reaches insects and pests in hard to reach areas through a multi-jointed elongated rod that hinges and pivots into various configuration to reach and entrap the insects with a pad of stacked, singular sticky sheets. The rod has a proximal end with a formed hole for hanging the apparatus from a distal end. At least one joint in the rod is fixedly set at a desired angle and orientation. The sticky sheets retain any insects which travel or fall into a base at the distal end of the rod. Each sheet is coated with a mild compression adhesive material that entraps an insect in response to an application of force against the insect. Each sticky sheet can be separated individually. Upon entrapment of an insect, the outermost sticky sheet restraining the insect is separated, folded to encase the insect, and disposed of.

Compositions used for cleansing hair and skin based on the combination of an ethoxy sulfosuccinate surfactant and an amphoteric surfactant are described that are very mild but do not compromise in-use properties and economy. It has been found desirable to utilize a mixture of a Mid-Chain alkyl ethoxy sulfosuccinate and a Long-Chain alkyl ethoxy sulfosuccinate wherein the Long-Chain component is present in the composition at a level from about 0.1% to about 6% based on the total weight of the Mid-Chain component.

The present invention provides a thick-film paste for printing the front side of a solar cell device having one or more insulating layers and a method for doing so. The thick-film paste comprises a source of an electrically conductive metal and a lead-vanadium-based oxide dispersed in an organic medium. The invention also provides a semiconductor device comprising an electrode formed from the thick-film paste.

Maternal and fetal birthing simulators are disclosed. The maternal simulator has a rotatable gynecoid pelvis, legs articulated at the hip and knee joints, and a deformable covering that simulates the feel of the skin and underlying tissues. The maternal birthing simulator may optionally be used with a pressure-based uterine propulsive system. The fetal simulator has an extensible spine, a movable head, movable clavicles, and arms articulated at the shoulder and elbow joints, and may include sensors to measure spinal extension, head rotation, applied traction force, and brachial plexus displacement.

Compositions used for cleansing hair and skin based on the combination of a sulfosuccinate surfactant and an amphoteric surfactant are described that are very mild but do not compromise in-use properties and economy. A route to solve the intrinsic instability of such aqueous compositions in storage has been developed based on the use of sulfosuccinic acid or a salt of sulfosuccinic acid present in an amount of at least about 4% based on the weight of the sulfosuccinate surfactant.
