摘要: A touch-sensitive input device includes a support, an input part with a touch-sensitive input surface, an elastic device which bears the input part at the support, an electromagnetic actuator which acts between the input part and the support to produce a deflection of the input part out of a resting position, and control electronics. The electromagnetic actuator comprises a coil with a cavity, a core arranged at least in part in the cavity, and an armature arranged outside the cavity. The core generates a magnetic field defining a pole direction. The armature interacts with the magnetic field. The control electronics generate an electrical control signal for the coil to produce the deflection of the input part out of the resting position and to provide a maximum deflection of the input part. A duration of the electrical control signal is limited so as to provide, after the deflection, a haptic feedback.

摘要: Disclosed are a grain-oriented electrical steel sheet having strain regions extending in a direction transverse to a rolling direction at periodic interval s (mm) in the rolling direction. Each strain region has a closure domain region whose width in the rolling direction varies periodically on a steel sheet surface. Each closure domain region satisfies: Wmax/Wmin=1.2 or more and less than 2.5, where Wmax and Wmin respectively denote a maximum width and a minimum width on the steel sheet surface as measured in the rolling direction; Wave being 80 μm or more, where Wave denotes an average width on the steel sheet surface as measured in the rolling direction; D being 32 μm or more, where D denotes a maximum depth as measured in the sheet thickness direction; and (Wave*D)/s being 0.0007 mm or more and 0.0016 mm or less.

摘要: Disclosed herein is a coil component that includes a coil pattern spirally wound in a plurality of turns. The coil pattern has an innermost turn positioned at an innermost periphery, an outermost turn positioned at an outermost periphery, a middle turn whose turn number counted from the innermost or outermost turn is intermediate among all the turns, and a center position of a line length. The coil pattern is designed such that a pattern width at the center position is larger than pattern widths of the innermost and outermost turns, and that a total or average value of pattern widths of turns positioned between the outermost turn and the middle turn is larger than a total or average value of pattern widths of turns positioned between the innermost turn and the middle turn.

摘要: An electromagnetic device may include an elongated core in which a magnetic flux in generable. The electromagnetic device may also include a first channel formed through the elongated core and a second channel formed through the elongated core. An inner core member is provided between the first channel and the second channel. The electromagnetic device may also include a primary winding wound around the inner core member and a plurality of secondary windings wound around the inner core member. An electric current flowing through the primary winding generates a magnetic field about the primary winding and the magnetic field is absorbed by the elongated core to generate the magnetic flux in the elongated core. The magnetic flux flowing in the elongated core causes an electric current to flow in each of the plurality of secondary windings.

摘要: In a system for wirelessly transferring power from a primary side across an airgap to a secondary side, the secondary side includes two parallel resonating circuits (27) each including two parallel resonating paths with a series connection of a resonating inductor (28), and a resonating capacitor 29. A rectifier (21) is connected to the output of each resonating path for converting the AC output (12′) of the resonating paths to a DC output (13′). The outputs of the rectifiers (21) are connected in parallel to provide the AC output power (13) to a load such as a battery or the like. Each resonating path further includes a symmetry inductance connected in series to improve current sharing among the resonating paths and to reduce the higher harmonic portion in the resonating paths. For balancing the flux each resonating circuit 27 includes in a preferred embodiment of the invention a symmetry winding (30) wound on the same core as the resonating inductor 28 of that resonating path where all symmetry windings (3) are connected in parallel to ensure optimal flux sharing.

摘要: The present invention relates to an electromagnetic shielding sheet capable of improving reliability. Particularly, the present invention provides a composite magnetic sheet for electromagnetic shielding structured such that an independent soft magnetic sheet, which has a low surface roughness, is laminated on the outermost surface of a soft magnetic sheet having a lamination structure, thereby implementing laminated composite sheets having different surface roughness or porosity characteristics; as a result, the reliability in an external hazardous environment, such as saline water, can be substantially enhanced while maintaining the efficiency of electromagnetic shielding.

摘要: The present disclosure relates to a tank of a high-voltage generator including a tank body and a tank lid. There is an opening in the tank lid. The opening is connected to the bellows so as to counteract the volume change of the transformer oil and avoid generation of bubbles. The tank includes a positive transformer, a negative transformer, a bellows, and other components. The high-voltage winding is embedded in the PCBs. The outer insulating bushing is covered by the PCBs so as to improve the insulativity between the turns of the high-voltage winding. In addition, oil barriers may be placed between the positive and the negative transformers, or between the transformers and the ground so as to eliminate the bridge breakdown effect and make the electric field uniform. By means of said measures, the present disclosure improves the stability of the high-voltage generator.
