    摘要: In an electrostatic micromotor, a mobile substrate faces a fixed substrate, and electrostatic-interaction elements are provided to allow a relative movement of the mobile substrate with respect to the fixed substrate in a direction of movement. The electrostatic-interaction elements include electrodes arranged on a facing surface of the fixed substrate (2) facing the mobile substrate. The mobile substrate has indentations, which extend within the mobile substrate starting from a respective facing surface that faces the fixed substrate and define between them projections staggered with respect to the electrodes in the direction of movement. Side walls of the indentations have a first distance of separation at the respective facing surface, and a second distance of separation, greater than the first distance of separation, at an internal region of the indentations.

The control circuit includes a semiconductor substrate, a communications circuit formed on the semiconductor substrate receiving data corresponding to an identification code from at least one external source within the vehicle, and a non-volatile memory formed on the semiconductor substrate and connected to the communications circuit for storing only once a predetermined identification code. The communications circuit writes the received data to the non-volatile memory as the predetermined identification code when the control circuit is within the vehicle if the predetermined identification code has not already been stored therein. The control circuit further includes a comparator formed on the substrate for comparing the received data with the predetermined identification code and providing a comparison signal. A selector is also formed on the substrate for enabling and disabling the operational circuit responsive to the comparison signal.

    摘要: A wafer of semiconductor material for fabricating integrated devices, including a stack of superimposed layers including first and second monocrystalline silicon layers separated by an intermediate insulating layer made of a material selected from the group comprising silicon carbide, silicon nitride and ceramic materials. An oxide bond layer is provided between the intermediate layer and the second silicon layer. The wafer is fabricated by forming the intermediate insulating layer on the first silicon layer in a heated vacuum chamber; depositing the oxide layer; and superimposing the second silicon layer. When the stack of silicon, insulating material, oxide and silicon layers is heat treated, the oxide reacts so as to bond the insulating layer to the second silicon layer. As a ceramic material beryllium oxide, aluminium nitride, boron nitride and alumina may be used.

    摘要: A series of Zener diodes (25) and an electronic power switch, such as an IGBT (18), are connected across a power supply. A circuit including a resistor (20) in series on the electronic switch, a threshold device (36, 38) connected to the resistor and a ramp generator with multiplier (40, 42, 44, 46, FIG. 2) or a thermal sensor (50, 44, 46 FIG. 3) detect the energy level dissipated in the electronic power switch when a transient occurs when the level exceeds a present value, the circuit supplies an output signal to a monostable circuit (26, 28, 48) to drive the electronic power switch with low resistance conditions for a preset time starting from the occurrence of the output signal. Another threshold device, connected to a resistor (30, 32), preferably senses the instantaneous power dissipated in the electronic switch to control the monostable circuit when the instantaneous power is higher than a preset threshold.

    摘要: This integrated semiconductor device aims at drastic reduction of the direct secondary breakdown phenomena and has a plurality of side-by-side elementary transistors forming an interdigited structure. To reduce the thermal interaction between the elementary transistors, the latter are spaced apart from one another by a distance approximately equal to the width of one elementary transistor and are driven by current sources. Spacing apart reduces electrothermal interaction. Further, in order to minimize the device area requirements, the space between any two adjacent elementary transistors is made to accommodate drive transistors operating as current sources, or the elementary transistors of the complementary stage where the device forms a class B output stage, the two output transistors whereof are alternatively switched on.
