摘要： An electrically erasable phase change memory utilizing a stoichiometrically and volumetrically balanced phase change material in which both the switching times and the switching energies required for the transitions between the amorphous and the crystalline states are substantially reduced below those attainable with prior art electrically erasable phase change memories. One embodiment of the invention comprises an integrated circuit implementation of the memory in a high bit density configuration in which manufacturing costs are correspondingly reduced and performance parameters are further improved.

摘要： Disclosed herein is a solid state, directly overwritable, non-volatile, high density, low cost, low energy, high speed, readily manufacturable, single cell memory element having reduced switching current requirements and increased write/erase cycle life. The structurally modified memory element includes an electrical contact formed of amorphous silicon, either alone or in combination with a layer of amorphous carbon layer. The memory element exhibits orders of magnitude higher switching speeds at remarkably reduced switching energy levels. The novel memory elements of the instant invention are further characterized, inter alia, by at least two stable and non-volatile detectable configurations of local atomic and/or electronic order, which configurations can be selectively and repeatably accessed by electrical input signals of designated energies. The reduced switching current requirements and an increased write/erase cycle life are achieved by structurally modifying the electrical contact with the aforementioned layer of amorphous silicon.

摘要： A conveyor oven is capable of heating precisely and uniformly an article to be baked as the article is conveyed through the oven at a designated speed. Precise and uniform heating is promoted by 1) a combination supply/return duct assembly positioned above the conveyor and configured to promote uniform airflow towards the upper surface of the conveyor, and 2) discharge orifices configured to further promote uniform airflow from the supply ducts without generating whistling or other unpleasant noises. The arrangement of this supply/return duct assembly, incorporating both supply and return ducts in the same plane, also promotes a low profile oven--an important consideration in applications in which minimizing space is a priority. The profile of the oven is reduced further by placing the heating element beneath the conveyor and by configuring supply and return passages to circulate air between the heat source and the supply/return duct assembly using minimal space. This air recirculation, preferably enhanced by seals at appropriate locations within the oven, also significantly increases the oven's thermal efficiency and its ability to distribute heat uniformly. The oven is especially well suited for use as a pre-bake oven in a print plate imaging and processing system.
