International Classification

H01L 29/74

U.S. Classification

257127, 257170, 257409, 257484, 257620, 257E23002

Abstract

An embodiment of the present invention is a technique to prevent reliability failures in semiconductor devices. A trench is patterned in a polyimide layer over a guard ring having a top metal layer. A passivation layer is etched at bottom of the trench. A capping layer is deposited on the trench over the etched passivation layer. The capping layer and the top metal layer form a mechanical strong interface to prevent a crack propagation.

International Classification

A63B 5504

U.S. Classification

248 97

Abstract

A foldable, lightweight, bag holder which supports a refuse bag so that the mouth of the refuse bag is held fully open when the bag holder is placed in either a vertical or horizontal position. The bag holder is simple to use and allows a person to sweep leaves, grass clippings, trash or other debris directly into the horizontally positioned refuse bag without having to use his or her own hands, or the help of another person, to maintain the refuse bag mouth in a fully opened position.

Appl. No.

Assignee

Westinghouse Electric Corp. (Pittsburgh, PA)

International Classification

H03B 530

U.S. Classification

331116R

Abstract

A crystal-controlled oscillator operable at a direct UHF frequency includes an amplifier having a feedback circuit formed from an SC-cut crystal and an impedance network. The impedance network provides an impedance load for the cyrstal, and the values of the individual components forming the impedance network are selected to provide an overall inductive load for the SC-cut crystal. Inductively loading the cyrstal permits the crystal to oscillate at the C mode or UHF frequency mode, and prevents unwanted crystal oscillation at the B mode or VHF mode.

U.S. Classification

428402, 977773, 977777

Abstract

A flash CVD process can be employed to grow micron- and nano-sized tree-like structures, particularly carbon structures on graphite electrodes. This process involves fast cyclic resistive heating of electrodes in an atmosphere of inert gas and hydrocarbons at below atmospheric pressure.

Assignee

Engelhard Corporation (Iselin, NJ)

International Classification

B32B 312

U.S. Classification

428116

Abstract

The present invention relates to a method of removing a coating, such as a spent catalyst coating, from a carrier such as a metal plate or a honeycomb carrier. The metal plates have a surface which has the catalyst coating. The honeycomb is of the type having a plurality of channels defined by honeycomb walls, the honeycomb walls the having a coating thereon. The method comprises directing a fluid stream which can comprise a cleaning liquid at the coated plate surface or into the honeycomb channels with sufficient force to loosen and remove at least some of the coating from the carrier surface. The carrier can then be separated from the liquid and dried. Where additional coating is to be removed, a stream of gas is directed at the carrier surface with sufficient force to loosen and remove at least some of the coating. The cleaned carrier can then be recoated. The present invention includes reclaimed and recoated articles.

International Classification

H03B 1900, H04B 1132

U.S. Classification

328 14

Abstract

A signal generator for high level low noise signals in which the preferred embodiment of the invention utilizes the output signal of a low noise crystal oscillator as a fundamental reference signal. The fundamental reference signal is multiplied to generate a series of coherent reference signals. Additionally, one of the coherent reference signals is coupled as an input signal to a divide circuit to generate at the output of the divide circuit a plurality of coherent low frequency reference signals. The coherent reference signals and the low frequency coherent reference signals are utilized by a synthesizer to generate a plurality of coherent signals having a frequency determined by the synthesizer. The output signal of the synthesizer is combined with one or more of the reference signals to generate the microwave output signal which is stepped from a minimum to a maximum value in equal increments.
