Abstract: A scanning system enables a user to nondestructively mark certain pages in a document stack and cause these page to be skipped during the scanning on a digital scanner. The pages of the document stack to be skipped are marked with a small adhesive backed label placed at a pre-defined location on the page by the user. The label is large enough to carry a simple, but unique image (machine-readable code) that can be read by a single sensor. The machine-readable code may be a barcode, glyph, color pattern, or reflective/nonreflective pattern, etc. The label's adhesive is such that it can be easily removed from the document stack without destroying the integrity of the page to which it was attached. In operation, the scanner utilizes a label sensor located before the scanning station/platen area so as to sense the skip label prior to the actual image capturing operation.

Abstract: A device for forming two twisted loops on the ends of a wire electrode to be used in scavengeless development. The wire is supported at both ends in a wire twisting apparatus and a specified tension is applied to the free ends of the wire. A crank is turned so that the both ends of the wire rotate at the same time. This causes the free ends of the wire to twist upon the suspended wire portion, two loops being formed at the ends of the wire. The twisted sections are stable and strong enough to maintain the loops when the wire is mounted in the development system.

Abstract: A dry etch process for etching a semiconductor substrate having a p-n heterojunction formed by contact between a p-layer and a n-layer requires application of a reverse bias voltage of less than a p-n breakdown voltage across the p-n heterojunction. A plasma containing chemically reactive negative ions is directed against the n-layer, with etching of non-masked regions of the substrate continuing until it is substantially stopped at the reverse biased p-n heterojunction. The semiconductor substrate can be cooled or periodically recoated with erodable protective material to limit sidewall damage to the semiconductor substrate while still allowing downward etching. This dry etch process is well suited for construction of dimensionally accurate microdevices and microelectromechanical systems.

Abstract: A composite resinold/graphite/diamond blade is described having enhanced precision cutting properties. The blade is made by assembling several layers, each layer comprising a veil of non-woven graphite fabric impregnated with a mixture of diamond particles blended into a phenolic resin. Layers are built up in sandwich fashion. In one embodiment described, four layers are formed and, in a heating compression molding operation, the sandwich is compressed into a composite blade having a diameter of 4.7 inches with a thickness of 0.011 inch. The final blade is formed by a die cut and lapping process. The layered construction yields a blade with more consistent cross-section and improves blade wear symmetry. In another embodiment, the layers are tailored to have a grit concentration of the diamond/resin mixture at the periphery or cutting edge.

Odd photosensors output video into an odd video channel, and even photosensors output video into an even video channel. The two video signals are time-staggered from each other by one-half cycle. The signals on the odd and even video channels are then multiplexed into a single high-speed channel.

Abstract: A user interface is provided facilitating the entry of at least one destination phone number into a phone number dialing routine. Upon entry of the phone number, the user interface allows a Start command, causing the phone number to be dialed by transmitting appropriate signals to a switching exchange. In the event a charge code is required, the user interface provides for separate entry for charge codes. A controller concatenates the phone number and the charge code number with appropriate timing inserted to allow the switching exchange to utilize the number and charge code.
