Abstract: An improved orthodontic bracket (44) has a slot (46) therein for receiving an archwire. The slot (46) has oppositely facing sidewalls (48 and 50) and a base (52). The base (52) has a protrusion (54) thereon thus forming a continuously curving surface including the sidewalls (48 and 50), the base (52) and the protrusion (54). An archwire placed in the slot (46) will rest upon the protrusion (54) rather than the base (52) or the sidewalls (48 and 50). Therefore, the archwire may be placed at a uniform depth regardless of the shape of the wire and stress is reduced in the slot (46).

Abstract: A polygonal-line characteristic amplifier has a minimum-voltage discrimination circuit (40;60), a maximum-voltage discrimination circuit (50) and a resistor dividing circuit (R1,R2;R3,R4). The minimum-voltage discrimination circuit detects and outputs a lower one of an input voltage (V IN ) and a predetermined reference voltage (V REF ) respectively applied to two non-inverting input terminals thereof. The maximum-voltage discrimination circuit detects and outputs a higher one of an output (V O(MIN) ) from the minimum-voltage discrimination circuit and a resistor divided voltage of the input voltage produced by the resistor dividing circuit respectively inputted to two non-inverting input terminals thereof. The maximum-voltage discrimination circuit outputs at its output terminal (30) an output voltage (V OUT ) having polygonal-line characteristics corresponding to the input signal applied to a signal input terminal (10). Since the voltage gain of the amplifier is low when the level of the input signal is high, the output voltage does not exceed its maximum value to thereby make a dynamic range large against the input level.

Abstract: The invention comprises a system of force sensors, especially for the dynamic determination of the axle load, speed, axle base and total weight of vehicles. The system of force sensors is laid permanently in the roadway. It is composed in a modular manner of the amplifier module (11), the sensor module (12) and the output module (13). The individual modules can be coupled tightly by means of plug connections, welded flange connections or bonded flange connections, with the result that lengths according to the roadway widths are obtained. The sensor module (12) consists of a hollow section (1), in which piezoelectric elements (4) are installed under elastic prestress. The piezoelectric elements (4) are accommodated in the hollow section (1) at spacings of, for example, 5 to 10 cm and can be connected as a whole by means of only one electrical conductive foil (5) or connected in groups or singly to the signal-processing unit (19). The road width can be subdivided, as required, according to the subdivision, for example in order to prepare the road load diagram. The hollow sections are so designed that they can be opened elastically by means of lateral clamping in such a way that a simple introduction of the mechanically interconnected piezoelectric elements (4) becomes possible. After this clamping has been released, the piezoelectric elements (4) are under high elastic prestress. Consequently, any tolerance errors can be overcome, and therefore there is no need for expensive mechanical machining, and all parts with standard tolerances can be used. <IMAGE>

Abstract: Primary coils generate flux upon being excited by a predetermined ac signal. A stator is made in a plate-like configuration and has plural primary coils independently in the circumferential direction so that flux is generated by the primary coils in the direction of the axis of rotation. A rotor is provided displaceably relative to the primary coils to change reluctance with respect to the flux generated by the primary coils. Accordingly, as the rotor is rotated, reluctance change is produced due to the relative positional relation between the primary coils provided in the stator and the rotor. This reluctance change causes to change self-inductance of the primary coils and affects the exciting ac signal flowing through the primary coils and, therefore, by outputting the self-induced ac signal in the primary coils, the relative positional relation between the rotor and the primary coils, i.e., the rotational position of the rotor, can be detected.
