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.

Abstract: A device or a pressure sensor for measuring a force or for measuring a pressure in a predefined direction. 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: An apparatus for interrupting the flow of current in a cable, which cable leads from the battery in a motor vehicle to a consumer, also located in the vehicle, such as the starter, engine or the like. A housing is provided, having two connection terminals, electrically insulated from one another, for the lines leading to the battery and to the consumer, and having a switch disposed in the interior of the housing, the switch being assigned a control device which can be tripped by a sensor and whose tripping actuates the switch.

Abstract: A laser cutting or trimming machine has a CO.sub.2 laser producing a laser beam and a guiding and reorienting system for directing the laser beam to a workpiece to be processed. The focal point of the laser beam and/or the laser beam output member lies on a first rotation axis, around which all of the guiding and reorienting means and the laser beam are rotatable. The laser beam and the focal point of the laser beam is pivotable about a second rotation axis, which is oriented perpendicularly to the first rotation axis. The laser beam output member can perform a conical motion about the second rotation axis, whereby the focal point or the apex of the cone described by the conical motion of the beam output member does not leave the intersection point of the first and second rotation axes. This conical motion of the laser beam output member is programmable and the workpiece to be processed is held on a mounting device programmably movable in three dimensions.

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: A robot for purposes of production and/or assembly comprises an arm carrying a holder for a tool, operating device or the like and being movable in three dimensions in consequence of appropriate guides. The holder itself can have various degrees of freedom through arrangement of hinges, rotational axes or the like and all holder movements for individual operating processes may be programmable. The holder is connected indirectly or directly to the arm through a double parallelogram linkage integrated into one unit, wherein the parallelogram linkage rod pairs extend obliquely one to the other, and a pivot angle displacing mechanism is associated with this linkage.

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.

Abstract: Filter phosphors consist of phosphor particles coated with a filter material. A phosphor which shows a red emission when excited by cathode rays may be coated with red iron oxide by producing a thin layer of pyrite on the phosphor particles and thereafter converting the said layer into hematite. Thus, the surface of the phosphor particles is evenly coated with a uniform, dense pigment layer of extreme adherence. The filter phosphors thus obtained are used in cathode ray tubes and especially in color picture tubes.
