320876 results about "Metal" patented technology

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride.

Method of making a cutting instrument having integrated sensors

A cutting instrument including a metal blade has a recess formed therein and a semiconductor substrate affixed to the blade in the recess. The semiconductor substrate includes at least one sensor formed thereon. The sensor formed on the semiconductor substrate may comprise at least one or an array of a strain sensors, pressure sensors, nerve sensors, temperature sensors, density sensors, accelerometers, and gyroscopes. The cutting instrument may also further include a handle wherein the blade is affixed to the handle and the semiconductor substrate is electrically coupled to the handle. The handle may then be coupled, either physically or by wireless transmission, to a computer that is adapted to display information to a person using the cutting instrument based on signals generated by one or more of the sensors formed on the semiconductor substrate. The computer or handle may also be adapted to store data based on the signals generated by one or more of the sensors. A method of making said cutting instrument includes the steps of at least one sensor being formed on a semiconductor wafer and a layer of photoresist being applied on a top side of the semiconductor wafer according to a pattern that matches the defined shape of the semiconductor substrate. The portion of the semiconductor wafer not covered by the photoresist is removed and thereafter the photoresist is removed from the semiconductor wafer, thereby leaving the semiconductor substrate having a defined shape and at least one sensor formed thereon. The semiconductor substrate having a defined shape and at least one sensor formed thereon is then affixed to a metal blade in a recess formed in said blade.

Method of forming metal layer using atomic layer deposition and semiconductor device having the metal layer as barrier metal layer or upper or lower electrode of capacitor

A method of forming a metal layer having excellent thermal and oxidation resistant characteristics using atomic layer deposition is provided. The metal layer includes a reactive metal (A), an element (B) for the amorphous combination between the reactive metal (A) and nitrogen (N), and nitrogen (N). The reactive metal (A) may be titanium (Ti), tantalum (Ta), tungsten (W), zirconium (Zr), hafnium (Hf), molybdenum (Mo) or niobium (Nb). The amorphous combination element (B) may be aluminum (Al), silicon (Si) or boron (B). The metal layer is formed by alternately injecting pulsed source gases for the elements (A, B and N) into a chamber according to atomic layer deposition to thereby alternately stack atomic layers. Accordingly, the composition ratio of a nitrogen compound (A-B-N) of the metal layer can be desirably adjusted just by appropriately determining the number of injection pulses of each source gas. According to the composition ratio, a desirable electrical conductivity and resistance of the metal layer can be accurately obtained. The atomic layers are individually deposited, thereby realizing excellent step coverage even in a complex and compact region. A metal layer formed by atomic layer deposition can be employed as a barrier metal layer, a lower electrode or an upper electrode in a semiconductor device.

Multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric, preparation method and application

The invention relates to a preparation method and an application of multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric. The multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is formed by successively arranging and laminating a metal foil reflection layer, a phase change temperature limitation layer, an interval composite membrane heat-insulation layer and a flame-retardant comfortable layer, wherein the metal foil reflection layer has high reflectivity and an enhanced heat-dissipation function; the phase change temperature limitation layer has functions of high energy consumption absorption and evenly-distributed heat conduction; the interval composite membrane heat-insulation layer has the functions of reflection insulation and even distribution of heat; and the flame-retardant comfortable layer has the functions of low-contact heat conduction, heat insulation and comfort. When the front side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric is under the action of open fire and strong heat flow environment, the back side of the multistage-spreading heat-dissipation fire-proof heat-insulation composite fabric can be kept below 50DEG C which is near the safe temperature state of the human skin, and the integral structural form and the mechanical property are stable. The natural thickness of the composite fabric is 5-15mm, the compression thickness of the composite fabric is 3-8mm, and the square meter quality of the composite fabric is 400-1500g/m<2>. The composite fabric is fire-proof heat-insulation material which is totally sealed, stuck and sewn and can be used for individual protection and environment heat insulation in special high-temperature occasions, such as fire control, military, exploration, safe escape and industry and the like.
