摘要:
A laminated LC element comprises a laminate including a plurality of bonded insulating layers, a first conductor including conductive elements which continuously extend around the insulating layers so as to form a coil having a predetermined number of turns; and a second conductor including second conductive elements which extend around the insulating layers, facing the first conductor via said insulating layers, and producing a capacitance with the first conductor. The LC element can eliminate firmly noises from external sources.

This invention relates to a deactivatable tag useable with an electronic article surveillance system and comprised of planar conductive material cut into a pair of inverse, first and second spiral conductors wrapped about each other and positioned for capacitive and inductive coupling. The invention also relates to method of making tags wherein conductors are cut from a planar web of conductive material in a continuous process in a manner that the cutting results in the formation of two spiral conductors without accompanying waste of conductive material, and thereafter positioning the conductors to provide resonant circuits. The conductors of each pair are connected by welding to provide a reliable circuit. A film of electrostatic-charge-draining material on a web of deactivatable tags prevents their premature deactivation.

An electrical device is provided forming an electrical component or circuit capable of performing such functions as storing, switching or gating electrical signals. The electrical device or circuit is formed at least in part of an anodizable, semi-conducting material by the controlled anodization or oxidation of a selected portion of such material to form a non-conducting portion thereof or a portion thereof in which the semi-conducting material has its capability of conducting electricity substantially reduced. In one form, the portion of the electrical device or circuit which is rendered non-conducting by oxidation or anodization serves to separate semi-conducting portions of the original semi-conducting material from each other. In another form, oxidation or anodization is effected to only partially insulate or isolate portions of the semi-conducting material from each other.

A high performance integrated tunable impedance matching network with coupled merged inductors. Embodiments include a combination of merged multiport constructively coupled spiral inductors and tunable capacitors configured to reduce insertion losses, circuit size, and optimization time while maintaining a high Q factor for the coupled spiral inductors. Some embodiments integrate one or more filter circuits with a tunable impedance matching network, useful in conjunction with such applications as radio frequency power amplifiers.

Some embodiments include a method in which a mixture of polynucleotide structures comprises a set of surface shapes. Surface shapes of some polynucleotide structures are complementary to surface shapes of other polynucleotide structures. The complementary surface shapes lock together along interfaces between adjacent polynucleotide structures to incorporate the polynucleotide structures into a polynucleotide mask. The polynucleotide mask is used during fabrication of features associated with a semiconductor substrate. Some embodiments include a method in which a semiconductor substrate comprises registration regions configured to adhere individual polynucleotide structures to specific locations of the semiconductor substrate. The adhered polynucleotide structures are incorporated into a polynucleotide mask which is used during fabrication of features associated with the semiconductor substrate.
摘要:
A high temperature reaction apparatus for reacting on solid, liquid and gaseous materials to change their state and/or chemical compositions. High temperatures are generated within a reaction chamber by means of electrical energy applied to electrodes or other means for generating radiant energy. The radiant energy may be in one or more forms such as a beam or a plasma. In a preferred form, the apparatus is controlled by a master controller such as a computer which generates control signals applied to control the admission of a reaction material or materials to a reaction chamber, the operation of one or more electrical energy to radiant energy generating means and, in certain arrangements, the removal or products of the high temperature reaction from the reaction chamber. Controlled chemical and/or physical reactions may thus be effected under computer control to perform such functions as incineration, the production of select chemicals, the refining of metals, the comminuting of solids, the vaporization of solid materials or select portions thereof, the production of select gases from vapors and solid materials and the coating of surfaces by particulate and/or vapor deposition. The apparatus may also be operated to provide combinations of such processes in a single reaction chamber or in a series of chambers joined together for the sequential and continuous processing of solid, liquid, vaporous and/or gaseous matter fed per se or as a mixture or separate streams thereof.
