    • A timing signal generator includes a demodulator for an input modulated signal to provide first and second baseband signals having a quadrature relation relative to each other. A converter is used to convert the first and second baseband signals into angle data representing a phase, and a calculator is used to calculate a difference between the phase represented by current angle data and the phase represented by previous angle data, preceding the current angle data by a 1-symbol interval. The calculator outputs data representative of the calculated phase difference. A further converter converts the calculator output data into a binary reference signal responsive to which of predetermined divided regions contains a point corresponding to the calculated difference data. Also included is a generator for generating a symbol timing signal in synchronism with the binary reference signal.

    • A liquid crystal display element including at least two kinds of spherical particles as a gap holding material in which each hardness is different in liquid crystal injected into a gap between a pair of substrates. Particle diameter accuracy of each particle is not more than 4%, a particle diameter of the particle with high hardness is not more than a particle diameter of the particle with low hardness, a number of the particle with high hardness to the particle with low hardness is 1 to 4, an average particle diameter of the particle with low hardness to the particle with high hardness is 1 to 1.05 and compression modulus of the particle with high hardness to the particle with low hardness is 1.14 to 14.3. As a result, gap uniformity can be improved. Moreover, occurrence of gap irregularity at the time of low temperature and of impact can be prevented.

    • A terminal unit apparatus for a time division multiplexing access radio communications system formed of a base station and a number of terminal units remote from the base station, includes a 2-dimensional adaptive equalizer circuit for equalizing two quadrature-relationship baseband signals which are obtained from a received quadrature digital modulation signal during receiving operation of the terminal unit, and an internal signal source which generates a local oscillator signal for use in demodulating a received signal to obtain these baseband signals. A frequency correction quantity is derived from the average rate of variation in each symbol interval of the ratio of the two main tap coefficients of the 2-dimensional adaptive equalizer circuit, and used to correct the frequency of operation of the internal signal source during both receiving operation and also in transmitting operation, in which the internal signal source provides a carrier signal for modulation. Frequency correction can thereby be achieved that is independent of the effects of multi-path interference to the transmission path upon the received quadrature digital modulation signal.
