Abstract: A transmission shift yoke (3) (see Fig 2) has to slide over the shift bar (1) and then be anchored accurately in the desired position by a fastener, i.e. set screw or bolt (8). The set screw must be locked to prevent its loss or more seriously its falling into machinery. The usual locking wire passed through holes near the head, is time consuming to make and wire up. Accordingly, an expansible snap ring (10) is arranged on a spotface (11) in a recess (12) in the bar; it is expanded by the tapered shank (14) of the fastener (8) and then snaps into a waist (19) of the fastener to prevent its being readily unscrewed more than half a turn or so. A really robust torque, however, on the head (9) by means of a spanner/wrench will forcibly expand the snap ring out of the waist (19) and over the widest part of the tapered shank (13). 
     The withdrawing force may dish or distort the snap ring rendering it unfit for further use, but the reduced time taken to instal or withdraw the fastener (as compared with wiring or unwiring) far outweighs such disadvantages.

Abstract: For winding and cross-cutting a web (11), use is made of a device having a first driving roller (21), which is mounted in pivotable supporting arms (22) and can be pressed against the outer circumference of the wound package (8) forming about a receiving roll (9). In a pivotable roller frame (1) is mounted a second driving roller (7) which can be brought into contact with a second receiving roll (9'), which is still to be wound. A group of deflecting rollers (14 to 17) is mounted in a common supporting structure, which, in turn, is mounted pivotably on the roller frame (1). Also arranged in the roller frame (1) are rollers (19) which can be pressed against one another of which at least one roller is driven. A cutting member (10) is arranged underneath said rollers (19) in the roller frame (1). The web (11) is so guided about the individual deflecting rollers (14 to 17) that the supporting structure (12) can be swivelled unimpeded together with said rollers into a position in which the web (11) loops round the receiving roll (9') still to be wound. The roller frame (1) and, in this, the supporting structure (12) can be swivelled in such a way that the deflecting rollers (14 to 17) are transferable into a position by means of which a part of the web (11) and the receiving roll (9') still to be wound form a gap (23) which narrows in the running direction of the web (11) and in the circumferential direction of the receiving roll (9'). This gap is situated underneath the two rollers (19) which can be pressed one on the other and the cutting point, situated below, for the web (11), so that the new web beginning is guided positively into the gap (23) without any other auxiliaries than the web (11) itself being necessary.

Abstract: A method for efficiently encoding character contours comprising decomposition of a character's pictographic representation into primitive geometric elements. The character is first divided into vertical or horizontal segments, which are themselves subdivided into smaller four-sided shapes. These shapes can take the form of trapezoidal or "curvezoidal" elements. In the latter case, the non-parallel sides of the elements are curvilinear segments rather than straight-line segments. The invention accommodates different fonts, point sizes and resolution requirements. Characters may be retrieved in real time for interactive WYSIWYG screen displays, or off-line for typesetting of high resolution text in a raster image processor; the representations contain sufficient information to drive screen displays and/or printer devices.

Abstract: A system for controlling a steering angle for rear wheels (15a,15b) of a vehicle is provided. This system is adapted for determining a rear wheel steering angle in a preselected relation to a steered angle (ϑ) of a steering wheel (2) and correcting the rear wheel steering angle based on a difference (ΔV) in rotational speed between front (6a,6b) and rear wheels (15a,15b) induced during turning. The rear wheel steering angle is however held without correction when the braking system is operated during turning to cancel the effect of braking slips on the determination of the rear wheel steering angle to improve steering stability.

Abstract: A laser wafer contains a facet (F) which is opposite the laser system (AF, AZ) and integrated in the wafer and which serves as a concave mirror for focusing the divergent light emerging from the laser system. The facet (F) is produced by etching out a depression (V) in the semiconductor substrate (S) containing the laser system by means of a dry-etching method. A two-dimensional curvature of the wall of the depression forming the facet and opposite the laser system is achieved as a result of the fact that the curvature in one dimension is determined by the shape of the opening bounding the depression in a photoresist mask which protects the surface of the substrate and in the other dimension it is achieved by an inclined angle of incidence of ions during the dry etching. <IMAGE>

Abstract: A network station's elasticity buffer includes a memory core together with write and read pointer logic. The memory core includes a START area and a CONTINUATION area which is a cyclic buffer. Under normal conditions, the read pointer follows the write pointer cyclically in the CONTINUATION area. However, upon detection of a start delimiter or upon station reset, the pointers recenter to the START area. Separate synchronizing logic is provided for each of the two recentering modes to reduce metastability problems caused by asynchronous sampling of data. A delay-by-one mechanism is built into the start delimiter mode synchronization scheme so that, under certain conditions, the read pointer is held in the CONTINUATION area for an additional read so an early sample of the read-start signal by the station's local clock while the read pointer is well behind the write pointer will not drop the last character of the previous frame when that frame is not separated from the next start delimiter by a sufficient interframe gap. A look-ahead-look-current detector insures that the there is not too much initial separation between the write pointer and the read pointer. A delay-GO mechanism is built into the reset mode synchronization scheme to prevent irregular dropping of line state characters when the local byte clock is trapped within the metastability window while clock drift is infinitesimal. The read pointer logic also includes a mechanism for preventing the delay-GO mechanism from creating too much initial separation between the write pointer and the read pointer.

Abstract: In a suspension controller 15 comprising a damper (12, 20) having a valve 46 switchable at frequencies within a desired activation frequency range between high and low damping modes, an unfiltered damper signal 120 is repeatedly derived from vehicle suspension related variables at a rate significantly greater than the desired activation frequency range. An output filter derives a filtered damper signal 130 from each successive binary actuator force signal by (1) resetting a timer each time the unfiltered damper signal 120 changes value, (2) causing the filtered damper signal 130 to be the same value as the unfiltered damper signal 120 if the time elapsed from the reset time has reached or exceeded a predetermined length, and (3) maintaining the filtered damper signal value unchanged if the time elapsed has not reached the predetermined length. The damper (12, 20) is controlled in response to the filtered damper signal 130, whereby unnecessary high frequency switching of the valve is reduced but the damper (12, 20) responds without unnecessary delay to signals within the desired activation frequency range.

Abstract: A moving image signal encoding apparatus comprises a frame decimating circuit for extracting encoded frames from an input moving image signal at specified intervals, a frame interpolating circuit for obtaining an interpolated frame between the encoded frames, and a circuit for obtaining an error formed by frame interpolation. A moving image signal decoding apparatus comprises a receiving circuit for extracting a frame code from an inputted signal, a frame decoding circuit for decoding the frame code to obtain a reproduced frame, and a frame interpolating circuit for obtaining an interpolated frame between the reproduced frames. By transmitting an error of the interpolated frame from the encoding apparatus to the decoding apparatus and correcting the error of the interpolated frame with the decoding apparatus, the error of the interpolated frame is eliminated. Alternatively, depending on the value of the error of the interpolated frame obtained with the encoding apparatus, circuit determines the operation mode as to whether the frame interpolating circuit of the decoder   carries out frame interpolation or preceding value holding and sends a flag to show the operation mode to the decoder, so that improvement is given when the error of the interpolated frame is large.
