摘要： Telephone set making it possible to engage in call mode and in answer mode and release a telephone line (L), connected to it, either by way of a first command produced by a first switching member (CC) actuated by the set's receiver, or equally by a command produced by a second switching member (14) which can be actuated independently of the receiver. … The switching elements (CC, 14) produce commands by way of individual elements for establishing communication (CC1, 14A) which are inserted in parallel in a loop linking, via a first arrangement for powering (5) a microprocessor (9) and a collection (10) of the set's telephone utilisation circuits, the output terminals of a diode bridge (2) whose input terminals are connected to the two line wires. A second diode bridge (6), used as a rectifier, linked by capacitors (7) to the line, in parallel with the first bridge is able to power the microprocessor and the collection (10), by way of a second arrangement for powering (8) from the alternating signals transmitted by the line during the ringing phases. … …

摘要： A device for dissipating heat for a surface mount component assembled onto a printed circuit board is made up by a metallic plate deposited on the rear of the substrate under the surface mount component. A thermal coupling device is made up by a small heat collecting plate provided on the front side of the substrate and the actual substrate. The heat collecting plate also performs an electro-magnetic shielding function and is advantageously constituted either by the shielding plate normally provided for this purpose or by an extension thereof.
