Title: Electrically Driven Oil Pressured Power Steering Apparatus
IPC: B62D6/02
Filed: 1981-07-27
Abstract: An electrically driven oil pressured power steering apparatus comprises an oil pump 6 driven by an electric motor 20 for supplying a working oil to a power cylinder 1, a control valve 7 for controlling the supply of the working oil, and a sensing means 28 and an electronically operated on-off means 27 which, in common, control a power supply to the electric motor 20. In the apparatus, a state of power steering is shifted to a state of manual steering when the electric motor is de- energised by the electronically operated on-off means. The sensing means 28 comprises a vehicle speed sensor 25 and a drive sensor 29 receiving a signal from a steering wheel, accelerator, brake or clutch pedal. A valve 10 interconnects lines leading to power cylinder chambers 1a, 1b when the electric motor is de- energised. A pressure relief value, Figures 9 and 10, interconnects supply and return lines of pump 6 when the steering apparatus reaches its full lock position. Power-assistance to steering may be reduced or eliminated above a predetermined vehicle speed. <IMAGE>

Patent GB-2090408-A (GB)
Title: Method of seismic exploration
IPC: G01V1/22
Filed: 1981-11-09
Abstract: A seismic data compression technique comprises sampling each individual seismic trace, operating upon a set number of samples to generate a predicted sample, quantizing the difference between the next sample and the predicted value of the sample, and storing and/or transmitting the quantum number so that the amount of information which need be stored and/ or transmitted is limited. In a preferred feature, a linear prediction differential pulse code modulation scheme is used to provide the predicted value, while an adaptive quantization scheme is used to quantize the error value to be transmitted, thus yielding further improvements in accuracy. A feedback loop can be applied to the decompression operation to limit quantization noise and further improve the fidelity of representation of the decompressed signals. <IMAGE>

Title: Disc Reproducing System for Compensating Mechanical Imperfections
IPC: G11B3/10
Filed: 1982-01-28
Abstract: A cartridge 60 on a tone arm 76 has a primary stylus 42 with a tip 44 for sensing the modulated grooves of a disc record 9. A secondary stylus 42A with a tip 44A is spaced in advance of the primary stylus and senses an unmodulated region of the disc, i.e. the surface provided by the lands, to derive a compensating signal which can be used to compensate for imperfections arising from record warp, rumble and pressing noise. The compensating signal is delayed by a delay circuit 280 whose delay is so adjusted in dependence upon the position across the disc of the tone arm 76 that the delay always corresponds substantially to the time taken for a point on the disc to travel from the stylus tip 44A to the tip 44. <IMAGE>

Title: Capacitive mask aligner
Inventor: NEUKERMANS ARMAND P
IPC: G01B7/31
Filed: 1984-10-12
Abstract: An aligner for aligning a mask and a wafer during photolithography of a semiconductor chip uses detection of the differential capacitance between two sets of conductive fingers on the mask and ridges on the wafer 3. An A.C. signal is coupled between the ridges and the fingers and the phase or amplitude of the signals is detected. An aligner utilizing multiple groups of ridges and fingers allows rotational alignment or two axis lateral alignment. An aligner having reference ledges to which the mask and the wafer are capacitively coupled allows alignment when the distance between the mask and the wafer is too great to permit meaningful capacitive coupling between the mask and the wafer to occur. The finger spacing may be regular, chirped or random. <IMAGE>

Title: Apparatus for replenishing a melt
Inventor: MENNA ANDREW A
IPC: C30B15/34
Filed: 1985-02-26
Abstract: Apparatus for replenishing a melt while a crystal growing operation is under way, wherein the apparatus comprises a hollow delivery tube and a hollow storage cannister surrounding the delivery tube. The hollow delivery tube comprises a side wall, an open upper end an an open lower end, and the hollow storage cannister comprises aside wall, an open upper end and a closed lower end, with the storage cannister's closed lower end having a central opening. The delivery tube and storage cannister are in concentric relation to one another, with the side wall of the delivery tube being received by and making a close sliding fit with the central opening in the storage cannister's closed lower end. The delivery tube's upper end resides inside the storage cannister while its lower end resides outside the storage cannister. A supply of source material for replenishing the melt is placed inside the storage cannister between the side wall of the delivery tube and the side wall of the storage cannister, and the lower end of the delivery tube is positioned directly over the melt which is to be replenished. During crystal growth, the storage cannister is moved in an upward direction relative to the delivery tube and as it does, source material in the cannister is carried upward above the upper end of the delivery tube and gravity causes it to automatically fall into the open upper end of the delivery tube which directs it into the melt. <IMAGE>
