Abstract: The invention relates to a hand machine-tool, especially electrical shears, comprising a housing (13) provided with a tool head (14) and a grip part (15), an electric motor (18) arranged in the housing (13), a switch (22) for the electric motor (18), and a drive shaft (16) mounted in the tool head (14), transversally to the housing axis. The drive shaft can be driven by the electric motor (18) by means of a transmission (19). The hand machine-tool also comprises a rotary tool (11) that can be fixed to the drive shaft (16). The aim of the invention is to create a compact, structurally small and lightweight hand machine-tool for work without generating fatigue. To this end, a small-volume, rechargeable energy accumulator, preferably a lithium ion accumulator (20), which feeds the electric motor (18) and has a high charging capacity, is arranged in the grip part, together with an electronic plate (21) and the switch.

Abstract: A dual-mode ring resonator including a planar conductor ring (1) of an approximately square shape with rounded corners (2,3,4,5) has a better resonator quality factor than has previously been obtained. The circumference or length of the conductor ring (1) is dimensioned so that the resonator is operated in one of its even-numbered harmonic modes.

Abstract: A voltage controller for a three-phase generator is disclosed in which the phase voltage of the generator is evaluated. This phase voltage is evaluated with the aid of a window comparator with variable thresholds. Via a VCL signal, which switches over each time a threshold adaptation occurs, a frequency-dependent signal can be generated that can be evaluated as a measure for the generator rpm.

Abstract: The sensor apparatus includes a sensor device having a control current (I.sub.H) flowing through it, a sensitivity and a temperature dependence of the control current characterized by a temperature coefficient, and a temperature compensating circuit for compensating temperature changes adversely effecting the sensitivity of the sensor device. The temperature compensating circuit includes a circuit portion which sets or adjusts the temperature coefficient of the control current(I.sub.H) according to changes in the temperature dependent internal resistance of the sensor device so that changes in negative temperature coefficients of other physical quantities determining the sensor sensitivity are compensated.

Abstract: The circuit arrangement for an auxiliary relay that actuates a starting relay for a starter device of an internal combustion engine includes a temperature measuring device (20) and a control and/or regulating circuit device (16,16') for controlling, in a turned-on state, an operating current (I) flowing through a relay coil of the auxiliary relay according to a temperature of the auxiliary relay or starting relay measured by the temperature measuring device (20) so that the operating current (I) and mean value of the operating current (I) are controlled according to the temperature. The control and/or regulating circuit clocks the operating current and can vary the duty cycle to reduce the power losses.

Abstract: A levelness adjusting device includes a positioning a unit mounted on a support surface for an actuator unit which is fixed on a frame, in which said positioning a unit comprises a base screw hole to play a support point, several adjusting screw holes which are located on a same circumference centering the base screw hole and are opened at positions adjusted to an inclination of the shaft for rotating a mirror body and several screws threaded into the screw hole so as to fix the actuator unit on the frame. The screw is penetrated from the actuator unit front portion to the frame via the screw hole which is formed on a periphery edge of the actuator unit. The screw is threaded into the base screw hole and the corresponding screw hole, and the actuator unit is positioned on the frame.

Abstract: The invention relates to a transmitting station (SS), and intermediate repeater (ZV1 to ZVn) and a receiving station (ES) for an optical communications-transmitting system for transmitting useful data of a high bit rate by means of at least one optically narrow-band carrier signal, and for transmitting additional data, for example service information, of a low bit rate. In order to operate the communications-transmitting system with the lowest possible outlay, an optically wide-band carrier signal, for example from a super-luminescence diode, which is located in the wavelength range of the narrow-band optical carrier signal, is used for transmitting the additional data. Both the optically narrow-band carrier signal of the useful data and the optically wide-band carrier signal of the additional data are located within the amplifying range of an optical fiber amplifier disposed in the intermediate repeater (ZV1 to ZVn). Both carrier signals can be selected with simple means.

Abstract: A sewing machine capable of embroidery stitching and a embroidery data producing device for the machine are formed so that optionally selectable data are provided for forming the stitches of unit patterns to be embroidered, for arranging the unit pattern in series along a linear outline forming a looped pattern, for setting the size and the number of the unit patterns, the space between the unit patterns in an arrangement thereof and the size of the looped pattern, and stitch forming means is operated under control of said given data to form the stitches of the unit patterns arranged along the linear outline.

Abstract: A device for load determination in an internal combustion engine with a turbo engine is described, wherein the auxiliary load signal determined from the throttle flap angle and the rpm is subjected to a compression compensation, wherein this compression compensation is performed in different operational ranges of the internal combustion engine with a turbocharger in different ways, wherein factors are respectively defined which are multiplied by the uncorrected auxiliary load signal.

Abstract: A headlight for vehicles has a reflector having at least two regions formed for different illumination functions, at least one light source associated with each of the regions of the reflector and having two light source elements, a lamp carrier fixed to the reflector, one of the light source elements being inserted in the reflector via the lamp carrier and held in the lamp carrier, the lamp carrier having a first portion fixed to the reflector and a second portion in which the one light source element is held, the second portion of the lamp carrier with the one light source element held in it being movable transverse to an optical axis of the reflector relative to the first portion of the lamp carrier for adjusting of the one light source element when the second portion is fixed to the reflector, the second portion of the lamp carrier being accessible from a backside of the reflector for moving the second portion relative to the first portion of the lamp carrier.
