Abstract: The present invention provides a bistable optical device in which the active medium is a polymer material (2) of thermo-optical effect inserted into a cavity resonator (1), preferably a FABRY-PEROT resonance cavity, in said cavity the polymer material transmitting and reflecting an incident light wave with bistable values and values variable according to its thermal state. This latter is varied by the absorption of a fraction of the incident light wave, which transfers heat to the polymer material to generate therein an increase in the transmission of the incident light and a variable refractive index in response to the increase in its temperature, to thus provide a positive response effect which enables the device of the present invention to vary between two bistable states.

Abstract: An image following apparatus for a vehicle capable of following a moving object such as a preceding vehicle with high reliability without being influenced by external disturbances. An image of the preceding vehicle(8)is successively sensed by a video camera(1)at predetermined intervals and stored in a first and a second memory (3, 4). A mirror image signal, which is symmetric to a basic image signal of the vehicle (8) for which a window is set, is stored in a mirror-image memory(5). A CPU(6A) makes a comparison between the basic image signal and a new image signal in a new window and updates the window at a location in which the image signal in the window has the best match with the basic image signal. A new image signal in the updated window is compared with a mirror image signal in the mirror-image memory so that the position of the updated window is adjusted to a location in which the new image signal is the most symmetric to the mirror image signal.

Abstract: For reducing the complexity of adaptive systems such as equalizers, echo cancellers and clock recovery systems, errors are often determined only once per n samples, where n is an integer. 
     If the input signal of such an adaptive system comprises cyclostationary components, it may occur that the adaptive system does not converge to a desired value. 
     By selecting n in such a way that the greatest common divisor of n and the cyclostationary period m of the input signal is equal to 1, convergence of the adaptive system is ensured.

Abstract: Disclosed is a facsimile apparatus equipped with an automatic answering telephone function, as well as a communication method in this apparatus. When a tone signal from a line is detected after the start of storage of a voice message in response to an incoming call, the voice message presently being recorded is not counted as a received message and a voice message received next is stored in the area in which storage has just been performed. Further, when a DTFM signal, which is a control signal of the automatic answering telephone, is detected, a transition is made to facsimile communication in response to a CNG signal. Thus, erroneous operation in facsimile communication due to a CNG signal recorded in the automatic answering telephone is prevented.

Abstract: Disclosed is an improved wire measuring apparatus comprising a wire guide roller mechanism 3 and a looper 5 to push down a fed wire to a descending position, thereby measuring the length of wire in terms of descending position at which the wire is held by the looper 5. The wire guide roller mechanism 3 comprises a frame, first, second and third guide rollers 6, 7 and 8 rotatably fixed to the frame. The first and third guide rollers 6 and 8 rotate in same direction, and the second guide roller 7 rotates in an opposite direction both in pulling the wire forward and backward. Also, the whole guide roller arrangement is designed to incline and follow the increasing or decreasing inclination of wire length ahead of the third guide roller. Thus, the wire curling inclination can be reduced from the measured wire. 
     The second guide roller acts to reduce the effect of the wires bending around the first guide roller and the wires extend tangentially from the third guide roller.
