Abstract: A temperature sensor having sturdy construction is simple to install and to package, is uncomplicated to manufacture, and suitable for reliably detecting rapid temperature changes. The temperature sensor (1) includes a silicon substrate (2) in which at least one porous area (3) is formed, the degree of porosity and the thickness of the porous area (3) being chosen so that the porous area (3) is thermally isolated from the silicon substrate (2). In addition, the temperature sensor (1) includes temperature measuring elements (6, 7) for detecting the temperature difference between the silicon substrate (2) and the porous area (3). The temperature sensor may also include heating elements for testing the sensor function.

A packaging element, as well as a carrier element, and a sensor element are substantially compensated in relation to the sensing region of the sensor element with respect to their temperature-induced expansions.

Abstract: For saving lateral space in a multitrack magnetic head, the connection lead paths (11, 12) run separately side by side along the outside surface of one magnetic layer (13) of the yoke and connect with the conducting strip that runs between the magnetic layers at the open end of the yoke by straps (18, 19) running around the side edges of the upper magnetic layer. Outside the region of the yoke these conductor straps are wider and are superposed one on the other, with an insulating layer between them, for lower resistance loss (see lower part of figure).

Abstract: To simplify a field plate effect speed and position sensor, particularly for association with the starter gear of an automotive-type internal combustion engine, four meander-arranged permalloy resistance tracks are located on a substrate at the corners of a rectangle, spaced, in circumferential direction, by about half the pitch distance of the teeth (2) of the starter gear. The resistances can be connected in a voltage divider (FIG. 4) configuration, or in form of a bridge circuit (FIG. 5) supplied from a constant current source (CC) to eliminate temperature variation affects, and providing alternating current output voltages within the wide range of temperature of essentially uniform level as the teeth (2) scan the sensor, a special marker tooth (10) providing an output signal of different level.
