20090033441 | DIELECTRIC PORCELAIN COMPOSITION AND HIGH FREQUENCY DEVICE USING THE SAME - A dielectric porcelain composition of the present invention includes a first component and second component. If the first component is represented by the general formula of xBaO—yNd | 02-05-2009 |
20090230596 | Method of manufacturing multi-layered ceramic substrate - An un-sintered multi-layered body includes a first ceramic layer having a surface, a conductor provided on the surface of the first ceramic layer, an insulator provided on the surface of the first ceramic layer and covering an end of the conductor, and a second ceramic layer provided on the conductor and the insulator. The un-sintered multi-layered body is baked at a temperature at which the first ceramic layer can be sintered but the second ceramic layer cannot be sintered. After the un-sintered multi-layered body is baked, the second ceramic layer is removed, thereby providing a multi-layered ceramic substrate. The insulator has a thickness not smaller than 10 μm and not larger than 40 μm. This method makes the insulator dense and allows the conductor to be formed easily. | 09-17-2009 |
20100254052 | STATIC ELECTRICITY COUNTERMEASURE COMPONENT AND METHOD FOR MANUFACTURING THE STATIC ELECTRICITY COUNTERMEASURE COMPONENT - An electrostatic discharge (ESD) protector includes a ceramic body having a cavity provided therein, and two discharge electrodes facing each other across the cavity. The discharge electrodes are made of metal containing more than 80 wt. % of tungsten. The discharge electrodes contain not more than 2.0 atomic % of tungsten bonded to oxygen to a total amount of tungsten contained in the discharge electrodes. This ESD protector does not cause a short-circuiting even upon having high-voltage static electricity applied to the discharge electrodes repetitively, thus having high reliability. | 10-07-2010 |
20110026186 | ELECTROSTATIC DISCHARGE PROTECTION COMPONENT AND METHOD FOR MANUFACTURING THE SAME - An electrostatic discharge protection component includes an element body, a pair of discharge electrodes, and a pair of terminal electrodes. The element body includes a closed cavity therein. The discharge electrodes are formed in the element body in such a manner as to be exposed to the cavity. The terminal electrodes are connected to the discharge electrodes, respectively, and provided on the element body. There is an oxide of at least one metal selected from zinc, niobium, aluminum, magnesium, calcium, sodium, and potassium attached to the surface of at least one of the discharge electrodes in the cavity. | 02-03-2011 |
20130285512 | PIEZOELECTRIC ELEMENT - A piezoelectric element includes a metal substrate, an alumina layer, a lower electrode, a piezoelectric layer, and an upper electrode. The metal substrate includes iron as a main component and includes at least aluminum and chromium. The alumina layer is formed on the metal substrate, and the lower electrode is formed on the alumina layer. The piezoelectric layer is formed on the lower electrode, and the upper electrode is formed on the piezoelectric layer. The alumina layer is mainly formed of particles in a γ-alumina phase. | 10-31-2013 |
20140327339 | PIEZOELECTRIC RESONATOR - A piezoelectric resonator including a base part, a first support part fixed to the base part, a beam part fixed to the first support part, a weight part fixed to the beam part, a drive unit provided on the beam part, and an adjusting magnet movable on a main surface of the base part. Furthermore, the weight part is formed of a magnet or a magnetic body, and the beam part extends in a direction along the main surface of the base part. With this configuration, displacement of the resonance frequency generated due to variation in a manufacturing process can be adjusted easily. Even when the resonance frequency is displaced from desired resonance frequency due to variation in the manufacturing process of a power generating element, the displacement can be easily adjusted and maximum efficiency can be obtained. | 11-06-2014 |
