4820-12-185-9931 4820121859931 121859931 is an item usually metallic, threaded or unthreaded, used for securing to or positioning into a mating part. it is designed to be used in a globe, relief, regulator valve and the like as a means of controlling the flow of liquids or gases in a given system. one end may have an integral disk or be designed to accommodate a metallic or nonmetallic disk. the other end is designed for a handwheel, lever, spring, diaphragm and the like for nonpowered operation or to accommodate a gear, solenoid, air motor and the like for powered operation. the handwheel and/or disk may be furnished with the item. excludes stem, faucet; and stem, needle valve.

5905-14-341-5918 5905143415918 143415918 is a resistor whose ohmic value cannot be adjusted or varied. the resistance element consists of either a thin layer of conductive material, containing either binders or insulating materials, deposited on an insulated form; or an alloy of metal and ceramic materials, usually fused to an insulated form. opposition to the flow of current is an inherent property of the materials used and is manifest by the heat dissipation in the resistor. see also attenuator, fixed and resistor, fixed, composition. excludes carbon composition type resistors.

5905-14-273-0825 5905142730825 142730825 is a resistor whose ohmic value cannot be adjusted or varied. the resistance element consists of either a thin layer of conductive material, containing either binders or insulating materials, deposited on an insulated form; or an alloy of metal and ceramic materials, usually fused to an insulated form. opposition to the flow of current is an inherent property of the materials used and is manifest by the heat dissipation in the resistor. see also attenuator, fixed and resistor, fixed, composition. excludes carbon composition type resistors.

5960-00-228-3759 5960002283759 002283759 is an inclosure, including two or more electrodes, in which a flow of electrons may occur through a vacuum or a contained gas. the electronic conduction takes place either by means of electrons emitted from a cathode or by ionization of the contained gas. includes phototubes (photoemissive type only), geiger-mueller tubes, traveling wave tubes, cathode ray tubes and microwave tubes (klystron, magnetron, or the like). excludes items whose primary purpose is to produce light energy. also excludes photoelectric cell; and semiconductor device (as modified).

5961-99-251-5978 5961992515978 992515978 is a two electrode semiconductor device having an asymmetrical voltage - current characteristic. may or may not include mounting hardware and/or heatsink. excludes light emitting diode and semiconductor device,photo. for items containing material such as selenium and copper oxide, see recifier, metallic.
