20120098627 | COMMON MODE FILTER - To pass an ultrahigh speed differential signal and sufficiently attenuate a common mode signal on an ultrahigh speed differential transmission line. A pair of conductor lines | 04-26-2012 |
20110279197 | COMMON MODE FILTER - To sufficiently attenuate a common mode signal by passing an ultra-high speed differential signal through an ultra-high speed differential transmission line. A common mode filter comprises: a pair of conductive lines formed on a first dielectric layer to transmit a differential signal; a plurality of first divided floating grounds in a state of being separated from an external ground potential, and facing the conductive lines, with the first dielectric layer interposed between them, and formed by being divided into a plurality of numbers in a length direction of the conductive lines, and forming a distribution constant type differential transmission line for the differential signal, together with the conductive lines; and a first passive two-terminal network connected between the first divided floating grounds located at least at an input side or an output side of the first divided floating grounds, and the external ground potential. | 11-17-2011 |
20110074525 | COMMON MODE FILTER - To pass an ultra high-speed differential signal and make it difficult to pass a common mode noise. Lamped-constant differential delay line DL is formed by arranging inductors Lo, being passive series elements, and capacitors Co, being passive parallel elements, in a differential four terminal network of a ladder shape composed of the passive series elements and the passive parallel elements arranged in differential lines | 03-31-2011 |
20110006795 | CONTACT PROBE DEVICE - To obtain a satisfactory contact state in an ultra high frequency range with a low loss, in a contact probe device with an electronic component connected to a mounting substrate. Insulating substrate | 01-13-2011 |
