Abstract: By transforming a duobinary signal, such cases are prohibited that a value of -1 is appeared again after a value of zero following -1 as shown in a string of -1 0 → -1 and a value of 1 is appeared again after a value of zero following 1 as shown in a string of 1 → 0 → 1. Narrow-band transmission is made possible by the fact that the direct current (DC) component of a duobinary signal can be eliminated without losing such natures thereof as to be ternary and reproducible original information by discriminating its even level as one (1) and its odd level as zero (0). Since the DC component can be eliminated, electromagnetic conversion systems are hardly subjected to distortion, leading to a reduction of probability of code errors.

Abstract: A process for manufacturing a GaAs FET in which a channel region (19) having a first doping level is provided on a substrate. A layer of gate material (20) is provided over the channel region and an etch mask (22) defining a gate over the channel is provided on the layer of gate material. Exposed portions of the layer of gate material are etched in sequence in which the etch mask is undercut by a first dimension to provide a T-structure. Source and drain regions are formed by implanting impurities into the channel to a second doping level the implant being self-aligned with the etch mask. The etch mask is removed forming a transition region having a doping level between the first and second doping levels by providing a thin conformal layer (51) of dielectric material over the source, drain and gate. In this way a substantially vertical wall of the dielectric material is provided adjacent the gate, which layer has a thickness less than the first dimension. Impurities are implanted at an implant energy and concentration whereby the impurities are masked by the wall and penetrate the dielectric material adjacent the wall to form the transition region.

Abstract: An end-of-tape detection apparatus provides a constant accumulated total of the revolutions of the supply and takeup reels rela­tive to the true end-of-tape defined by the leader-to-tape splice. Counter means (34, 36) stores a value indicative of the true end-of-tape, and also counts and stores the accumulated total of revo­lutions as the tape is wound onto a reel. There­after as tape is pulled from the reel, the ap­proaching end-of-tape is accurately known in terms of the remaining revolutions of the reel. A microprocessor (46) uses the stored value to determine the point at which deceleration of the tape should begin, whereby the tape rapidly is decelerated to a selected speed just prior to true end-of-tape. The tape is stopped upon sensing the leader-to-­tape splice.

Abstract: A solid state sensor, micromachined in silicon, comprises first and second beams which can be optically excited into resonant vibration. The first beam is arranged to be acted upon by a diaphragm, so that the tension in it, and therefore its resonant frequency, is affected by the pressure applied to the diaphragm. The second beam is provided for temperature correction purposes, and to this end is positioned close to the first beam but free at one end, so that it is insensitive to the pressure applied to the diaphragm, while being subject to the same temperature variations as the first beam. Additionally, the second beam is positioned sufficiently closely to the first beam that it can be optically excited simultaneously with the first beam via a single optical fibre.

Abstract: A fibre spray system for depositing fibres on to a substrate or article comprises a vibrating feeder bowl (66) having an opening (20) in its side wall covered by a grid or screen (96) through which fibres loaded into the feeder bowl (66) are discharged into a fibre collector (106). A delivery hose (130) is connected between the fibre collector (106) and a pump (136) which is operative to create a negative pressure within the fibre collector (106) to draw fibres through the grid (96) of the feeder bowl (66), out of the feeder bowl (66) into the fibre collector (106) and to entrain the collected fibres within a stream of air. The air-­entrained fibers are drawn through the delivery hose (130) to the pump (136), and in the course of passage therethrough the velocity of the fibres is reduced so that they collect or accumulate within an area in the delivery hose (130) upstream from the pump (136). The pump (136) uniformly withdraws fibres from the area where they accumulate and discharges the fibres directly into a spray gun (20) connected to the pump for deposition on to a substrate.

Filed: 1989-03-15
Abstract: The device has a track (1) with at least one guide rail (4, 5, 6, 7) on which there stands a vehicle (F). The guide rail (4, 5, 6, 7) includes two current conducting rails (4, 5) to which an adjustable electric voltage is passed via leads (16, 17) from a control device (S). Sliding contacts (18, 19) fitted on the vehicle (F) and to which there is connected an electric drive motor (M) make contact with the current conducting rails (4, 5). When the vehicle (F) skids, i.e. when the longitudinal axis of the vehicle deviates from the direction determined by the guide rail (4, 5, 6, 7) by a predefined angle, a control circuit is connected to a timer (23) via additional sliding contacts (12, 13) and contact rails (6, 7), via at least one additional contact element (26, 27) in or on the vehicle (F). The timer (23) then opens a switch (22) in the power supply lead (16) to the motor (M) for a predefined time interval. A driving error resulting in skidding of the vehicle (F) is thus punished by interrupting driving for the predefined time interval. The vehicle (F) is not simply thrown off the guide rail (4, 5, 6, 7). <IMAGE>

Title: Method for bending bar-shaped materials
Inventor: ZAHLAUS HELMUT
IPC: B21D11/12
Filed: 1987-03-16
Abstract: The machine is capable of bending reinforcing steel rod (142) accurately in either direction by using just two bending slides (144) and (146). The two bending slides hold the material (142) in alternating sequence i.e. when one slide holds the material, the other carries out the bending. The holding of the material in a particular section is effected by bending crank (152) swinging around bending mandrel (154) and bending the rod by a specified angle alpha which, for the material in question is within the elasticity limit of the rod. Actual bending takes place, but the elastically deformed section of the rod produces the clamping effect between the bending roll and mandrel.
