Abstract:
A layered inductor 10 is manufactured by layering "silver-based conductive layers" and "ferrite-based magnetic layers" and simultaneously firing these layers. The conductive layers are via-connected to form a helical coil 30. A shape of a cross sectional surface of the conductive layer, cut by a plane perpendicular to a longitudinal direction of each of the conductive layers is a substantial trapezoid shape, having an upper base and a lower base L1. A base angle θ of the trapezoid shape at both ends of the lower base is equal to or greater than 50° and is smaller than or equal to 80°.
Abstract:
Die Erfindung betrifft einen RFID-Transponder für den Einsatz in einer RFID-Anordnung mit induktiver Kopplung, wobei zur Führung des magnetischen Flusses das Zusammenwirken einer Sende- und Empfangsspule (SP) mit einem Ferrit-Bauteil (LAFC) vorgesehen ist. Dabei besteht das Ferrit-Bauteil (LAFC) zur Führung des magnetischen Flusses aus einem Verbundwerkstoff aus einem Kunststoff und Ferritpulver, wobei der Kunststoff laserstrukturierbar ausgerüstet ist, so dass die Sende- und Empfangsspule (SP) durch zumindest eine mittels einer Laserbearbeitung vorkonturierten und anschließend metallisierten Leiterbahn (LB) in oder auf der Oberfläche des Bauteils gebildet wird. Ein solcher RFID-Transponder ist robust, leicht und einfach herstellbar.
Abstract:
The present invention relates to a flexible display screen composed of a plurality of flexible display modules jointed side by side, each of said flexible display modules comprising a flexible circuit board, which is fixedly arranged with a plurality of display chips on its front face, and a plurality of magnets on its back face, so that said flexible display screen can be attracted on a metal medium by means of said magnets, so that said flexible display screen can be attracted on a metal medium by means of said magnets, wherein the magnets are distributed at least on the perimeter of the back face of the flexible circuit board in such a way that the joining sides of two adjoining flexible circuit boards are arranged respectively and symmetrically with a same number of magnets, and each pair of magnets disposed on the respective joining sides having opposite polarity orientations. During the assembly of the flexible display screen according to the present invention, each flexible display module can be guided to joint with each other under the action of a specially-arranged magnetic attraction, avoiding the mis-arrangement during the assembly, so as to realize an easy and correct assembly. Furthermore, under the action of the magnetic attraction, the gap between the adjoining flexible display modules is reduced, allowing a larger tension of the flexible display module when it is attached to the medium, so as to improve the display effect of the flexible display screen and the overall quality and the visualization of the product.

Abstract:
The present invention provides electrically conductive sheet materials (10) that contain columns of electrically conductive particles aligned to form continuous columns (19) between lateral faces of the conductive sheet material (10). The particle columns (19) are arranged so that the sheet is conductive through the thickness, but is electrically insulating in lateral directions. The present invention also provides methods by which such electrically conductive sheet materials (10) can be made. The present invention is able to provide conductive pathways in a precise, regular array, at a very fine pitch.
Abstract:
The invention provides a composition (3) comprising: (i) a ferrofluid comprising a colloidal suspension (4) of ferromagnetic particles in a non-magnetic carrier liquid, and (ii) a plurality of electrically-conductive particles (5) having substantially uniform sizes and shapes, dispersed in the ferrofluid. Various types of substantially non-magnetic electrically-conductive particles (5) are described. Application of a substantially uniform magnetic field by magnet means (8) to the composition (3) causes the electrically-conductive particles (5) to form a regular pattern (9). The composition is used for providing anisotropic conductive pathways (9a, 9b) between two sets of conductors (2a, 2b; 7a, 7b) in the electronics industry. The composition may be a curable adhesive composition which bonds the conductors. Alternatively or in addition the electrically-conductive particles may have a latent adhesive property e.g. the particles may be solder particles. The ferrofluid may be a colloidal suspension of ferromagnetic particles in a liquid monomer.
