Title: Automotive steering assembly
Inventor: KOKUBU SADAO
IPC: B62D1/10
Filed: 1987-03-31
Abstract: An automotive steering assembly which has a steering pad maintained stationary independently of the steering wheel operation is disclosed. The assembly employs a sun and planetary gear system in transmission of rotary motion to the steering shaft. The steering wheel is rigidly attached to the steering shaft while the sun and planetary gear system contributes to maintenance of the orientation of the steering pad. In the sun and planetary gear system, the role of the sun portion is played by a timing belt whereas that of the planetary portion is played by a rotary gear wheel. The above timing belt and planetary gear wheel are adapted to be disengaged from each other upon entry of foreign matters including sand grains or the like.

Abstract: A read channel circuit includes a high frequency filter (14) and a pair of differentiators (16, 18), one of which is a high resolution differentiator (16) and the other of which is a low resolution differentiator (18) intentionally adjusted to perform its differentiation function imperfectly. Comparators (32) serve as zero crossing detectors for the high and low resolution signals. The comparator for the low resolution path provides the data input to a flip-flop (34). The compara- torforthe high resolution path has its output processed by an exclusive OR gate (38) and a delay circuit (44) before being applied to the clock input (46) of the flip-flop. The high-resolution and low-resolution paths are combined in the flip-flop (34), whose digital output faithfully reproduces the binary information received by the read head by deriving timing from the high-resolution path and by effectively discriminating against artifacts in the read head's signal which would result in spurious transitions in the read channel's output were it not forthe imperfect differentiation provided in the low-resolution path.

Abstract: In a cross-connection network, a plurality of asynchronous input digital signals can be cross-connected to a plurality of output lines (21l to 21n) by use of time switch (31). The input digital signals are pulse stuffed at a common higher bit rate and are synchronized to one another by attaching extra bits. The pulse stuffed signals are assigned into serial frames in a predetermined order by the multiplex technique and are interchanged from one to another by the time switch (31) in the time division fashion. The frame-interchanged signal is demultiplexed to reproduce the pulse-stuffed signals which are sent out to the respective output lines (21l to 21n) assigned to the frames after removing extra bits. When the input digital signals are of higher order group, each of the higher order group digital signals is demultiplexed to lower order group signals which are pulse stuffed to be synchronized to the common higher bit rate. The pulse stuffed lower order signals are rearranged by the multiplex technique to reform each of the high order group signal which is synchronized to one another. The reformed higher order group signals are assigned in serial frames and are processed in the similar manner as described above. The frame-interchanged signals are reversely processed to be   separated, demultiplexed, destuffed, and multiplexed to reproduce the input signals as the output signals.

Abstract: A pedal (11) is provided for actuating a booster and master cylinder assembly (10) to apply the separate brakes (5, 6, 7 and 8) on four respective wheels (1,2, 3, 4) of a vehicle for normal service vehicle retardation. The assembly (10) is adapted to be operated independently of the pedal (11) to apply the brake on at least one driven wheel of the vehicle when the acceleration of that wheel sensed by a speed sensor on that wheel exceeds a predetermined value. This is achieved by a solenoid-operated traction-control valve (65) of which the operation is controlled by the signals from an electronic control module (45), which forms an integral part of an anti-lock facility for the vehicle. The control valve (65) is adapted to control the generation of servo-assistance for the assembly independent of, and by-passing, a servo-pressure control valve (42) which is operative to control the generation of servo assistance for the assembly in response to pressure generated by operation of the pedal (11).

Title: Infrared-radiation detector device
Inventor: BETHEA CLYDE G
IPC: H01L31/09
Filed: 1988-01-07
Abstract: A narrow-bandwidth, high-speed infrared radiation detector is based on tunneling of photo-excited electrons out of quantum wells. Infrared radiation incident on a superlattice of doped quantum wells gives rise to intersubband resonance radiation which excites electrons from the ground state into an excited state. A photocurrent results from excited electrons tunneling out of quantum wells. Conveniently, Group III-V materials can be used in device manufacture. Preferably, quantum well potential barriers are shaped so as to facilitate resonant tunneling of photocurrent as compared with dark current. Preferred device operation is at elevated bias voltage, giving rise to enhancement of photocurrent by a quantum-well-avalanche effect.

Abstract: There are described apparatus and methods for producing time-varying of trellis-coded modulations, specifically, time-varying trellis-coded phase-shift-­keying, to facilitate carrier phase recovery when the signal has been exposed to extraneous phase variations and noise. 
     Typically, eight-phase-shift-keying (8-PSK), with rate 2/3 convolutional coding, is followed on a repetitive basis by one or two formats of four-phase-shift-keying (4-PSK), which formats are chosen to ease phase synchronization and to conserve the use of bandwidth and not to worsen the bit error probability while reducing the probability of synchronization loss and the length of error bursts or "random walks". 
     The variation of the modulation formats could be:
     1) 8-PSK (rate 2/3) followed by 4-PSK,   2) 8-PSK (rate 2/3) followed by 4-PSK (preferred format) and then 4-PSK (secondary format) or,   3) any of many other periodic formats of 8-PSK and 4-PSK sections.   
     The use of this improved type of modulation is contemplated, for example, mobile radio links, particularly to counteract fading, or for optical fiber links to counteract other cause of signal degradation.
