Abstract: The invention relates to an ignition system, particularly of the static-distribution type, in which a respective ignition coil (C) with a primary winding (5) and a secondary winding (6) is coupled to the spark­ing plug (SP) associated with each cylinder. The system includes a respective switching transistor (T) for each ignition coil (C) and control circuit devices (4, 7 -11) which, in order to generate a spark in a plug (SP), cause a first switching of the corresponding transistor (T) from the shut-off condition to the conducting con­dition to start the flow of current in the primary wind­ing (5) of the associated coil (C), and a second switch­ing to the shut-off condition to stop the flow of cur­rent in the coil (C), causing the striking of the spark. These control circuit devices (4, 7 - 11) are arranged to control the speed of the first switching of the transistor or transistors (T) concerned from time to time, for each ignition, so that the first switching takes place gradually at a speed less than a predeter­mined value. The amplitude of the voltage peak which is applied to the sparking plug (SP) in correspondence with the first switching is thus drastically reduced.

Abstract: The transducer comprises a support structure (1,10,15) carrying piezoresistive sensors (8), particularly of the thick-film type, which are intended to be resiliently deformed by the fluid pressure to be measured and to provide an electrical signal indicative of the value of the pressure. The support structure comprises a substantially mushroom-shaped metal body (1) with a head (2) and a shank (3). An axial blind hole (4) is formed in the shank (3) and is intended to contain the fluid whose pressure is to be measured. The hole (4) also extends into the head (2) and, with the end surface of ti′e head, defines a wall (6) which is resiliently deformable by the pressure to be measured. The piezoresistive sensors (8) are connected to the end surface (2a) of the head (2) of the mushroom-shaped body (1) in correspondence with or adjacent the deformable wall (6) so that they can in turn be deformed as a result of the deformation of the wall. The sensors (8) are deposited on a thin plate (7) fixed to the upper surface of the head (2) of the mushroom-shaped body (1). The plate also carries the components (9) of the circuits for amplifying and processing the signals generated by the sensors (B). A metal structure (10,17) is also connected to the mushroom-shaped body (1) to screen it from radio-frequency interference.

Abstract: In order to detect relative linear displacements between two members (S, C), the transducer includes a fixed part or stator (1) connectible to one of the members (C) and a movable part or rotor (2) rotatably supported by the fixed part (1). A flexible traction member (5) has one end anchored to the other member (S) and its other end connected to the rotor (2) in such a way as to cause rotation of the latter in one sense relative to the stator (1) when the members (S, C) move away from each other. The transducer also includes a return spring (3) which tends to rotate the rotor (2) in the opposite sense of rotation when the two members (S, C) move towards each other. Electrical sensor means output electrical signals indicative of the angular position of the rotor (2) relative to the stator (1) and hence of the relative position of the two members (S, C).
