Abstract: A turbocharger for an automotive vehicle is comprised of a rotatable shaft having a cup-shaped section to which an axial projection of a turbine wheel is fitted under a shrinkage fit. The rotatable shaft is rotatably supported by ball bearings. A nut is screwed on the rotatable shaft in a manner to clamp the ball bearings together with a compressor wheel between it and the cup-shaped section. The inner race of the ball bearing on the turbine wheel side is in axially tight contact with an abutting surface formed in the rotatable shaft. In this arrangement, a setting is made to safisfy the following formala: 
 
       ℓ/P ≧ 0.002           
 
 where ℓ is a distance (mm) in the rotatable shaft, between a bottom inner surface of the cup-shaped section and the abutting surface; and P is an axial tensile force developed by screwing up the nut in the direction of the cup-shaped section.

Abstract: An exposure system for electrophotographic apparatus having an aperture plate for masking one or more laser beams. The plate (30) contains one or more apertures (52, 54, 56) which have irregular edges to form a gaussian light distribution for the light beams passing through the apertures. A saw-toothed edge is used with a predetermined amplitude ratio to predictably attenuate the light at the edges which correspond to the process or in-track direction in the exposed image. The gaussian distribution is more tolerable of spacing changes in scan lines and improves the continuity of process direction lines in the finished image.

Abstract: A coherent optical multichannel receiver includes a frequency down-conversion stage (10) having a laser local oscillator (12) for producing an IF signal which is applied to two frequency detection paths (26,28), the outputs from which are subtracted in a subtractor (30) to provide a data signal. AFC signal producing means (18,34) are also connected to the subtractor (30). In order to avoid a false lock occurring when the receiver is out-of-lock, detection means are provided for detecting an out-of-lock situation. The detection means is coupled either to a bandpass filter (36 or 38) to alter a property of the bandpass filter when the receiver is out-of-lock so that the subtractor (30) provides a positive output which is used to offset the frequency detection characteristic so that it has a single positive zero crossing or to an offset voltage input V ofs  in the AFC loop. The offset is removed automatically when the receiver returns to a lock situation.

Abstract: A hue compensation apparatus outputs hue-compensated data of a color designated by an input color selection signal of red, green and blue, responsive to red, green and blue input signals. The hue compensation apparatus uses first (48), second (50) and third lookup table (52) circuits, a decoder (54), a polarizing circuit (56,58,60) and a synthesizing circuit (62). The lookup table circuits output hue-compensated red, green and blue signals in response to input red, green and blue signals, respectively. The decoder decodes the input color selection signal, and the polarization circuit (56,58,60) polarizes outputs from the first, second and third lookup table circuits according to an output of the decoder. The synthesizing circuit (62) synthesizes the polarized output from the first, second and third lookup table circuits. The synthesizing circuit (62) thus outputs a hue-compensated color signal whose color is designated by the color selection signal (46) by synthesizing the polarized outputs from the polarization circuit.

Abstract: A light-emitting edge structure emitting light of non-uniform intensity from different regions of the edge has a uniform light emission filter provided across the light-emitting faces of the edge. The filter takes the form of an exposed photographic emulsion coated directly onto the light-emitting faces of the edge. Alternatively, the filter takes the form of a separate substrate containing the exposed photographic emulsion mounted across the light-emitting faces. The exposed emulsion is darker at regions thereof which correspond to regions of the light-emitting edge faces with higher original light intensity and lighter at regions thereof which correspond to regions of the light-emitting edge faces with lower original light intensity. The final exposed emulsion reduces the original non-uniform intensity of the light from the different regions of the light-emitting faces to a uniform level equal to that of the lowest original light intensity of the light-emitting faces. A focussing lens can be combined with the edge emitter structure. The filter emulsion is exposed so as to compensate not only for non-uniformity of light intensity of the structure but also for optical non-uniformities of the lens.

Abstract: In a program and method for concurrently interfacing multiple application programs to an emulation session running on a multi-tasking workstation of a network, parameters representing the functions to be performed by the application programs on the emulation session resources are compared for compatibility by an emulation interface program. For application programs with compatible parameters, the functional requests are processed or queued depending on the lock status. Application program requests directed to the interface program are queued when subject to a lockout. The parameters for determining whether application programs are permitted concurrent access to the emulation session include a default set, which set is invoked and suitable to represent a classic application program of non-multi-tasking vintage.

Abstract: The current transformer (8) intended for a medium- or high-voltage system exhibits a current sensor (9) and an annular support body (13) used for holding the current sensor (9). The current sensor (9) held by the support body (13) is constructed as toroidally wound coil (14) and, after installation in the system, concentrically surrounds a current conductor (5) of the system. This current transformer is intended to have small dimensions and to be distinguished by a current sensor (9) which can be installed without problems at any point in the system. This is achieved by the fact that the coil (14) is wound in a manner of a Rogowski coil onto an annular core (23) of non-ferromagnetic material of essentially rectangular cross section cut in the axial direction with a small radial dimension in comparison with the radius of the core (23) and with its axial extent, and is arranged in a hollow space (13) of hollow cylindrical construction in the support body (13) which is shielded against electrical fields. <IMAGE>
