Abstract: PURPOSE: To improve the adjusting speed of searching an antenna to a correct direction by controlling the phase of plural mixed signals to add depending on a phase difference between each mixed signal and a sum signal. CONSTITUTION: A phase discriminator 95 is provided with two output sides 96 and 97, to which signals are respectively sent, and these signals are in corporation with the sine or the cosine of a phase angle between the inputted signals to a phase discriminator. Control voltage is fetched from the output sides 98 and 99 of back-end low-pass filters 100 and 101, and control voltage expressing the real part of a coefficient Wi is led to the multiplier circuit 41 to 4n of each from the output side 99.

Title: Dynamic brake device
Inventor: MIZUNO TSUTOMU
IPC: H02P3/22
Filed: 1989-12-01
Abstract: PURPOSE:To increase braking power and reduce braking distance as well as braking time by a method wherein a braking resistance circuit is provided with the (b) contact of a time returning type timer, which short-circuits one part of control resistance after a given time from the demagnetizing of an exciting coil of an electromagnetic contactor. CONSTITUTION:A resistance R1 is in a braking circuit until a time (t1) whereat the contact (b) of a timer T is closed. The contact (b) of the timer T is closed from the time (t1) and, therefore, the value of resistance of the braking circuit becomes R1R2/(R1+R2) which is smaller than the resistance R1 whereby a current is increased and a thrust is increased. Accordingly, decelleration is increased and a braking distance may be reduced. The value of resistance is changed once during braking, however, the value of resistance may be changed a plurality of times or continuously.

Title: Driving method of display device
Inventor: MIKI AKIRA
IPC: G02F1/133
Filed: 1991-11-27
Abstract: PURPOSE:To form mutually suppressive coupling between cell units and obtain a pattern which varies with a slight signal input by setting the amplitude of a signal to be amplified or the amplified signal from an amplifier to positive- negative a symmetry through a deforming means. CONSTITUTION:The deforming means PD for the signal wave to be amplified is connected to the input side of the amplifier 34 which constitutes a network circuit and through this means, the amplitude of the signal to be amplified or the amplified signal from the amplifier 34 is set to positive-negative a symmetry. For example, when the positive bias is set higher than the negative bias, the positive bias applied to the cell units 30 gradually attenuates with the distance from the cell unit group 30 in an ON state and the cell units themselves have leak current components, so the potential of the whole field further decreases. Therefore, a mutual coupling intensity distribution wherein only the cell unit group in the ON state is high in potential and the potential gradually decreases with the distance is obtained. This is similar to the mutual coupling intensity distribution of a neural network and the mutual suppressive coupling is formed.
