Abstract: This invention provides a small sized inductance coil and in particular, provides a small sized flat type inductance coil (11). The inductance coil (11) comprises a coiled electroconductive member (15) having a wide dimension and a narrow dimension in directions intersecting one another in cross section and coiled so that the direction of the wide dimension of said coiled electroconductive member (15) is parallel to a coiling axis of said coiled electroconductive member (15) and that an outline of said coiled electroconductive member (15) is formed in a plane. 
     According to the above structure, the inductance coil (11) does not become so large, because the width of the electroconductive member (15) in the direction which is parallel to the plane is small.

Abstract: A quantizer (38), with quantization control that is sensitive to input signal characteristics and to output buffer fullness, responds to an input signal that is divided into blocks and DCT transformed (in 37). The transformed signal is analyzed to develop a brightness correction and to evaluate the texture of the image and the change in texture in the image. Based on these, and in concert with the human visual perception model, perception threshold signals are created (in 49) for each subband of the transformed signal. Concurrently, scale factors for each subband of the transformed signal are computed, and a measure of variability in the transformed input signal is calculated (in 49). A measure of the fullness of the buffer (56) to which the quantizer sends its encoded results is obtained, and that measure is combined with the calculated signal variability to develop a correction signal. The correction signal modifies the perception threshold signals to develop threshold control signals that are applied to the quantizer (38). The scale factors are also applied to the quantizer, as well as a global target distortion measure.

Abstract: A wide-screen television receiver capable of converting a TV signal of a non-aspect ratio into a signal of a wide aspect ratio which can be displayed on a wide screen of the wide aspect ratio and previously visually informing the user of what part of the image of the non-aspect ratio TV signal is converted in its aspect ratio and displayed on the wide screen. The receiver includes the interpolation scan speed conversion circuit (102), the mode setting circuit (104), the aspect ratio converting circuit (103), the wide cursor adding circuit 105 and the wide display (106). The interpolation scan speed conversion circuit (102) makes a series of processes such as Y/C separation and scan line interpolation for the input video signal supplied via the input terminal (101). The aspect ratio converting circuit (103) compresses the video signal from the interpolation scan speed conversion circuit (102) in the horizontal direction by use of a memory. The magnification processing circuit (109) is provided after the aspect ratio converting circuit (103). This magnification processing circuit (109) magnifies the horizontally compressed video signal so that an arbitrary part of image specified by the mode setting circuit (104) can be magnified at given magnification powers in the horizontal and vertical directions. The wide screen display (106) displays the magnified image of the video signal without horizontal and vertical distortions on the wide screen.

Abstract: A tungsten carbide chisel insert for rolling cone rock bits has a cylindrical base section and a cutting tip section, the top of the tip section having an elongated or chisel crest. The remainder of the cutting tip section below the crest is formed having cross-sections having no non-tangential intersections along their outer periphery. Such an insert used on the gage of a rock bit has a larger nose radius at the outer end of the insert crest than at the inner end, thereby providing more mass on the portion of the insert that contacts the borehole sidewall. Another chisel insert has a crest with a "dog bone" shape rounded with the crest ends flaring out to a larger dimension than the middle thereof. The crest is also convex upwardly along its median line, thereby making a shorter moment arm at the ends of the crest.

Abstract: The tendency of a motor-driven actuator 1 driving against a dynamic (non-frictional) load to return upon reaching the limit switch 22 sufficiently to again close the limit switch and create a persistent oscillation at the limit position can be prevented by placing a positive temperature coefficient thermistor across the limit switch involved. Such loads typically arise in actuators having spring-driven return capability, and can also arise when positioning air dampers and other loads where the actuator force is opposed by a spring or gravity.

Abstract: In order to accelerate an asynchronous machine (5), its stator is connected via a switch (S2) to a secondary winding (W3) of a converter transformer (T1), while the rotor is connected via a cycloconverter (3, 4), in a V-circuit, to secondary windings (W2, W3) of the converter transformer (T1). The secondary winding (W3) has a reduced AC voltage (U12) on the converter side, in the region of 5% - 10% of the AC voltage (U1) of the AC power supply (1). The asynchronous machine (5) is coupled on the rotor side to a single-phase synchronous machine (6). Such rotating frequency converters are used for transmitting electrical power in the range from 8MW - 90MW from a national grid (1) at 50 Hz or 60 Hz to a single-phase railway network (2) at 16<2>/3 Hz or 25 Hz, and vice versa. The single-phase synchronous machine (6) is not energised during acceleration, so that undesirable harmonic torques at double the stator frequency do not occur and a longer life of mechanical components, such as pole connections, fans etc., is achieved. <IMAGE>

Abstract: In a system for recording and reproducing a digital audio signal on/from a re-recordable record carrier, comprising a recording arrangement for recording the digital audio signal in a track on the record carrier and comprising a reproducing arrangement for reproducing the digital audio signal from the track of the record carrier, measures are provided to prevent audible distortion from occurring during a transition from a terminal portion of an original recording to a start portion of a new recording partly recorded over the original recording. 
     This has been realized by mutilating, such as scrambling, at least part of the start portion of the new recording, so that error flags are generated during reproduction. These error flags result in a muting of the audio information which includes the audible distortion. Other ways of concealment are also possible to conceal the audible distortion. 
     Mutilating the signal to be recorded can also mean that a concealment codeword is included indicating the transition. Upon detection of the concealment codeword, the concealment control signal is generated, resulting in a concealing of the distorted audio signal.
