摘要： A metal alloy which when oxidized forms a highly conductive surface oxide layer. Alloy compositions such as, but not limited to, Ti—Nb, Ti—Ta, La—Sr—Cr, and La—Sr—Co are known to form oxide passivation layers which are highly conductive. Such alloys are useful in electrical contact apparatus. An electrical contact element formed of the alloy has a contact surface which when oxidized forms a highly conductive surface layer, thus maintaining electrical conductivity and continuity through the element. The oxide layer may be formed in situ after assembly of the electrical contact or may be provided in an oxidative step during manufacture. The electrical contact may be formed entirely of one or more of such alloys; or may be formed of an inexpensive substrate base metal, such as steel, having one or more of the alloys coated thereupon; or may be formed of a mixture of the base metal and the alloy.

摘要： System and methods for determining a concentration of urea in an aqueous solution disposed in a container are provided. The system includes an infrared light source and an infrared light detector. The system further includes a window disposed proximate to an aperture of the container, such that the infrared light at a first light intensity level from the infrared light source passes through a first portion of the window toward the aqueous solution. A portion of the infrared light is absorbed by the aqueous solution, and a second portion of the infrared light is reflected from the aqueous solution and through a second portion of the window. The infrared light detector system generates a first signal indicative of a second light intensity level based on the second portion of infrared light. The system further includes a microprocessor that determines the second light intensity level based on the first signal, and further determines a urea concentration based on the first and second light intensity levels.

摘要： The invention generally includes a method of selectively etching a body of silicon material wherein a silicon wafer is used as a working electrode and having an n-type region and a relatively shallow p-type layer. The working electrode and a counterelectrode are placed in a liquid etchant. High voltage pulses, greater than 2 V are applied between the working electrode and the counterelectrode so that holes from the p-type layer are injected into the n-type region and etching is stopped due to oxidation of the n-type region. The technique is useful in producing very thin n-type membranes.

摘要： A method of selectively etching a body of a semiconductor material, such as single crystalline silicon, having regions of n-type and p-type conductivity to remove at least a portion of the n-type region. The body is placed in an etching solution of an etchant having a high pH value and a positive voltage is applied between the body and the etchant. This forms passivating layers on the surfaces of the two regions with the passivating layer on the n-type region being different from that on the p-type region. The voltage is then removed and the body is etched for a period long enough to remove all of the passivating layer from the n-type region and at least a portion of the n-type region, but is not long enough to remove all of the passivating layer from the p-type region. This is allowed by the difference between the passivating layers on the two regions. The steps of forming the passivating layers and etching them is repeated until a desired amount of the n-type region is removed.
