Abstract: A coil comprises a layer of permeable material (4) deposited in a chip (CH) of an integrated circuit (IC) in a plane substantially parallel to a surface (A) of a substrate (1) of the chip (CH). A first conductor element (6a, 6b; BW10, BWI 1; 60a, 60b) is arranged at a first side of the permeable material (4) facing away from the substrate (1). A second conductor element (2a, 2b; T1, T2) is arranged at a second side of the permeable material (4) opposite to the first side. An interconnection (8a, 8b; P2, P4) interconnects a first end of the first conductor element (6a, 6b; BW10, BWI 1; 60a, 60b) and a first end of the second conductor element (2a, 2b; T1, T2). The interconnection (8a, 8b; P2, P4), the first conductor element (6a, 6b; BW10, BW11; 60a, 60b) and the second conductor element (2a, 2b; T1, T2) are arranged to form a winding around the permeable material (4).

Abstract: A flat and thin accumulator device (10) includes a planar electrochemical cell (100) with at least two laminar electrodes (16, 18) having opposite polarities, arranged on either one of the two sides of an electrolyte material (12, 13), a moisture-proof envelope (51, 52, 53) having two foils (70A, 70B) which form substantially plane faces of a moisture-proof and electrically insulating material. The faces are interconnected in a peripheral sealing area (81A, 81B, 81C, 81D) and electrical contacts (26, 28) of the electrodes form electrode terminals which extend through the peripheral sealing area. The envelope further includes tabs forming extensions of the electrode terminals which have electrical contact areas with the electrode terminals, the tabs and the contact areas longitudinally extending in a sealed manner through the peripheral sealing area, and openings are made transversely through the peripheral sealing area which correspond to the tabs so as to uncover the two opposite faces of the tabs.

Abstract: An accumulator device for an apparatus intermittently operating between a back-up rest state and an active state includes at least first and second accumulator assemblies. A connection circuit is provided for connecting the assemblies to the apparatus and includes at least one switch element, and a control circuit of the switch element connects the second accumulator assembly to the apparatus during the active state.

Abstract: A sealed casing is provided for withstanding a certain pressure. The casing contains an electric accumulator, and is formed by at least one wall which has at least one closing area formed by a plastic band for connecting two edges of the wall. The closing area includes an adhesive part and a shiftable part to form an effective and economical closure.

Abstract: A battery is disclosed having two electrodes, each with a conductive strip connected thereto. A separator separates the two electrodes and an insulating envelope encloses the two electrodes. The two electrodes extend from openings of the insulating envelope and curve over the envelope toward the battery center.

Abstract: An accumulator device for an electric or electronic apparatus includes an active element for charging and for producing electric power, and a casing for the active element. In order to counterbalance the pressure increase occurring during the charging operation of the active element, the casing for the active element is curved.

Abstract: A flat accumulator device (10) includes a planar electrochemical cell with at least two planar electrodes (2, 2') having opposite polarities disposed on either one of the two sides of an electrolyte material (3, 4), a planar housing having planar parts (1, 1') and enveloping the planar electrochemical cell, and electrical contacts (30, 30') of the electrodes forming external electric terminals fixed in a moisture-proof manner to the planar parts of the housing. In this device, the flat accumulator includes a security portion (31, 32; 31', 32') which forms a circuit breaker that can be triggered by a short-circuit produced between the electric terminals of the housing.

Abstract: A battery is disclosed having a frame with conducting parts which are separated by insulating parts to form a cavity. The battery includes a cell located in the cavity having electrodes connected to the conducting parts. An insulating cover foil covers the cell. The conducting parts extend substantially along two sides of the frame. In addition, an insulating foil is located over inner surfaces of the conducting parts, where the inner surfaces face toward the cavity. Instead a single cell, many cells may be provided in the cavity, where the cells are vertically stacked over one another connected either in parallel or in series.

Abstract: A moisture-proof housing is disclosed intended for containing a battery. The housing includes two walls or plates which are kept in place by a sealing band located therebetween which defines interior of the housing. Portions of the walls, namely wall or plate protrusions, extend beyond the sealing band. One of the plates has a hole located exterior to the housing during normal conditions. The sealing band includes a movable part which slides between the two plates. When the interior housing pressure exceed the exterior pressure, the movable part slides outward to include the hole within the housing interior. This provides a safety valve and vents out the excessive interior pressure. A stop device is provided to avoid excessive displacement of the movable band, such as displacement beyond the plate protrusions.
