Abstract:
A foldable substrate is provided that includes a first substrate portion with a first upper surface and a second substrate portion with a second upper surface. A foldable bridge portion couples the first substrate portion to the second substrate portion. The foldable bridge portion includes a coupling strip that extends from the first substrate portion to the second substrate portion with a gap corresponding to a portion of the coupling strip where the gap is defined between the first and second substrate portions by removing portions of a starting wafer substrate. The first and second portions, in one embodiment, include magnetic field sensors and the foldable bridge portion can be bent to arrange the two portions at a predetermined angle to one another. Once bent, the sensor package can be incorporated into a magnetic field sensor assembly to be integrated with other control circuitry.
Abstract:
The invention relates to an electric charger for an accumulator or a battery or the like, which is adapted for rapid charging during an on-period and comprises for this purpose control means for starting and ending the on-period. The charger is provided with a circuit for converting a supply voltage to a charging current for the battery, and further with a heat-absorbing member in heat-conducting coupling with at least an electrical component of the circuit to be protected against overheating. The control means are adapted such that the on-period cannot be restarted during an off-period following the on-period. The electric charger can hereby comprise a heat-absorbing member with a relatively low heat loss, this saving space and cost.
Abstract:
Provided are a polyimide resin composition containing a polyimide obtained by the condensation of: a diamine component containing an aromatic diamine (A) represented by the general formula (1-1) or the like, a silicone diamine (B) represented by the general formula (2) and an aliphatic diamine (C) represented by the general formula (3); and an acid anhydride component containing a specific aromatic tetracarboxylic dianhydride (D); and a laminate and a device using the polyimide resin composition.
Abstract:
The invention relates to an electrical circuit assembly (1), particularly for a control device of a motor vehicle, having a first circuit board (2), at least one second circuit board (3) and at least one holder (4) for holding the second circuit board (3) on the first circuit board (2), producing an electrical contact (6) between the first (2) and the second (3) circuit boards. According to the invention, the second circuit board (3) is preassembled on the holder (4) and the preassembled unit (5), comprising the second circuit board (3) and holder (4), is connected to the first circuit board (2), wherein the holder (4) and the second circuit board (3) are arranged crosswise, particularly at a right angle, to the first circuit board (2). The invention furthermore relates to a control device and to a method for producing an electrical circuit assembly (1).
Abstract:
Die Erfindung betrifft eine elektrische Baugruppe mit einem Gehäuse (1), enthaltend wenigstens zwei gleichartige elektrische Bauelemente (21, 22), die in Bezug auf eine Kenngröße aneinander angepaßt sind, und mit Anschlüssen (311, 312, 321, 322) zur separaten Kontaktierung jedes einzelnen Bauelements (21, 22). Die Baugruppe kann vorteilhaft bei Telekomanwendungen verwendet werden, wo zwei Telefonleitungen mit Thermistoren derselben Widerstandsklasse bestückt werden müssen.
Abstract:
Die Entwärmung von integrierten Leistungsbauelementen soll einfacher gestaltet werden. Hierzu wird eine Wärmeübertragungseinrichtung, insbesondere eine thermisch leitende Matte (3), zwischen die zu kühlenden Bauelemente (2) und einem Kern eines induktiven Bauelements (4) eingefügt. Die von den Leistungshalbleitem (2) produzierte Wärme kann somit an den Kern des induktiven Bauelements (4) abgegeben werden.
Abstract:
The invention relates to an electrical subassembly comprising a housing (1) that accommodates at least two electrical components (21, 22) of the same kind, which are adapted to each other regarding one parameter, and connections (311, 312, 321, 322) for separately contacting each individual component (21, 22). The inventive subassembly can be used in an advantageous manner for telecommunication applications in which two telephone lines have to be fitted with two thermistors belonging to the same class of resistance.
Abstract:
A circuit board electrical connector includes a plurality of multicontact connectors (1) to be mounted on a circuit board with a predetermined interval; a plurality of linking members (6) for joining the multicontact connectors with the predetermined interval before the multicontact connectors are mounted on the circuit board; and linking devices (7-10) for removably linking the multicontact connectors to the linking members.
