A steering assist mechanism for use in a vehicle having a steering linkage and an engine. The steering assist mechanism includes a driving unit having input and output ends. The output end being connected to the steering linkage. The steering assist mechanism also includes power take-off means adapted to connect the engine to the input end of the driving unit. The steering assist mechanism further includes an electromagnetic clutch in the driving unit between the input and output ends, and control means which are responsive to the torque exerted through the steering linkage to increase the energization of the clutch, whereby the steering linkage is driven by the power take-off means in a direction tending to reduce the torque.

A memory may be implemented with a stable chalcogenide glass which is defined as a generally amorphous chalcogenide material that does not change to a generally crystalline phase when exposed to 200° C. for 30 minutes or less. Different states may be programmed by changing the threshold voltage of the material. The threshold voltage may be changed with pulses of different amplitude and/or different pulse fall times. Reading may be done using a reference level between the threshold voltages of the two different states. A separate access device is generally not needed.

A pore cathode for use in a deposition chamber for the plasma enhanced deposition of photovoltaic materials onto one or more webs of substrate material. The cathode is planar and serves the dual functions of (1) an electrode for the plasma deposition process and (2) a distribution conduit for the flow of fresh reaction gas to and for the evacuation of the spent reaction gas from the plasma region to maintain a uniform, constant pressure plasma reaction. The gas outlet pores of the inventive cathode are uniquely sized, shaped and spaced to provide new plasma chemistry and physics to insure optimization of the zoo of chemical species within the plasma regardless of deposition speed. That is, the distribution of ions, electrons, free radicals and neutral species in the plasma are optimized to deposit high quality photovoltaic semiconductor material while also increasing the utilization of the process gases, thus allowing the economical mass production of amorphous silicon solar cells having at least 8% photovoltaic efficiency on large area substrates. The pores can be covered by gas dispersion plates which prevent direct, line-of-sight, flow of the process gases to the adjacent deposition substrate and more uniformly distributes the gases flowing into the plasma region between the cathode and the substrate, thus minimizing the effects of non-homogeneity of the depositing species.

An error reduction circuit for use in arrays of chalcogenide memory and computing devices. The error reduction circuit reduces the error associated with the output response of chalcogenide devices. In a preferred embodiment, the output response is resistance and the error reduction circuit reduces errors or fluctuations in the resistance. The error reduction circuit includes a network of chalcogenide devices, each of which is nominally equivalent and each of which is programmed into the same state having the same nominal resistance. The inclusion of multiple devices in the network of the instant error reduction circuit provides for a reduction in the contributions of both dynamic fluctuations and manufacturing fluctuations to the error in the output response.

A hydrogen storage alloy having an atomically engineered microstructure that both physically and chemically absorbs hydrogen. The atomically engineered microstructure has a predominant volume of a first microstructure which provides for chemically absorbed hydrogen and a volume of a second microstructure which provides for physically absorbed hydrogen.

The atomically engineered microstructure may include porous micro-tubes in which the porosity of the micro-tubes physically absorbs hydrogen. The micro-tubes may be at least 5 volume % of the atomically engineered microstructure. The micro-tubes may provide proton conduction channels within the bulk of the hydrogen storage alloy and the proton conduction channels may be at least 5 volume % of the atomically engineered microstructure.
