Abstract: A motor vehicle rear wheel suspension is specified with a wheel suspension element held directly on the wheel carrier, which element comprises a first control arm outside the wheel and a second control arm inside the wheel. Both control arms are pivoted by way of flexible joints on the vehicle body, the one joint of the first control arm being made longitudinally flexible and, together with the other flexible joint of the second control arm, forming a control arm axis of rotation running roughly transversely, and an imaginary wheel steering pole behind the wheel's axis of rotation and outside the track width. The wheel suspension element comprises a spring strut, formed as part of a wheel-inner control arm, positioned obliquely in relation to the longitudinal centre axis of the vehicle and connected to a control arm body via a wheel adjustment device. As part of the wheel-inner control arm this spring strut has a shorter length than an adjoining rigid part of the control arm. The spring strut is of flexibly deflectable construction and holds the wheel-outer control arm formed in one piece with the body of the control arm allowing limited displacement via the body-side control bearing. …<IMAGE>…

Abstract: A decoder is capable of decoing on a maximum likelihood basis coded symbols of equivalently high coding rate which are produced by deleting those code bits which are located at particular positions in a time sequence of convolutional symbols of low coding rate. The decoder includes a serial-to-parallel (SP) converter for converting a serial data sequence from a dummy bit inserter into parallel sequences. The frequency division phase of the SP converter is determined by a second timing signal which the dummy bit inserter produces in synchronism with a dummy bit insertion phase. As code synchronization is established, frequency division phase synchronization is automatically established. This eliminates the need for the repetitive trial for frequency division phase synchronization only and thereby reduces a synchronization capture time.

Abstract: A polycarbonate polymer or copolymer is synthesised from a dihydroxydiarylalkane which can be halo-substituted; the highly transparent polymer can be mixed with up to 50 wt% of a polystyrene and is molded into a film or sheet, e.g. by extrusion, and uniaxially stretched, preferably by tentering so as not to cause a neck-in ratio or more than 10%. 
     The stretched film has its optical phase retardation controlled to cause (a) a retardation of phase difference of ½ an average wavelength of natural light of wavelength 550 nm with its retardation value controlled to 200-350 nm, preferably 250-300 nm, (b) full retardation of the actual wavelength with its retardation at 475-625, preferably 525-575 nm or (c) an intermediate retardation value of 350-475 nm. The film also has a color difference or lack of unevenness of not more than 20 determined with a spectro­photometer on usually 10 at random locations of the sample film whilst illuminated through crossed Nicol prisms with the film set so that its main optical axis is at 45° to the Nicols. 
     The retardent films are useful in optical filters and liquid crystal displays.

Abstract: An overwritable magneto-optic recording system has a recording medium (10) with a substrate (11), a recording magnetic film (13) and a reproducing magnetic film (12) deposited on the substrate. The reproducing magnetic film (12) has a Curie temperature lower than that of the recording magnetic film (13), and coercive force Hc higher than that of the recording magnetic film. In a write process, a magnetic head (16) writes data magnetically on the recording magnetic film (13), and then, in a transfer process, an optical head (14) (which is positioned downstream in the direction of relative movement of the recording medium and the optical head) heats the recording medium higher than the Curie temperature of the reproducing magnetic film (12) so that the reproducing magnetic film loses its magnetic property. During the cooling period after heating, recorded bits in the recording magnetic film (13), are transferred to the reproducing magnetic film (12) which restores its magnetic property. In the reproducing process, the optical head (14) irradiates the reproducing magnetic film with a polarised coherent beam, and the data is reproduced on the principle that the polarisation of the reflected beam depends upon the recorded data based on the Kerr effect.

Abstract: Transmitter for transmitting communication traffic via phase modulated carrier signals. The device provides for an efficient amplification of a phase modulated carrier signal using Class C amplifier (19) technology. An envelope function is applied to the carrier signal by modulating the Class C amplifier (19) with a related spectrum-suppressing amplitude envelope signal. Phase distortion accompanying the amplitude modulation of the Class C amplifier is compensated by generating a phase offset for the carrier signal. As each envelope function for suppressing the spectrum is generated, a corresponding phase offset may be applied to the carrier signal, avoiding the consequences of phase shift resulting from amplitude modulating the carrier signal in the Class C amplifier (19).
