Abstract: A method of treating the surface of substrates used in liquid crystal display cells so that the surface forces the liquid crystal director to be aligned uniformly over the entire surface and parallel to the substrate surface. The method includes the step of forming a plasman beam containing oxygen free-radicals, inert gas free-radicals such as argon, neon and helium, and free radicals of a compound containing the element to be deposited, for example, silicon, tin, indium, etc. Preferably a volatile organo-silicon or an organo-tin compound is used to supply the silicon or tin. The plasma beam is then directed at the substrate surface at an angle, preferably of about 30°, for a time sufficient to deposit a film. The liquid crystal display cell utilizing a substrate formed in this manner has a high contrast ratio as well as a sharp threshold in its electro-optical characteristics.

Inventor: GRIFFIS PATRICK DOUGLAS
IPC: H04S5/00
Filed: 1980-03-07
Abstract: A system is provided which synthesizes stereophonic sound by developing two separate sound channels from a single monophonic sound source. The system may be advantageously utilized in combination with a visual display such as a television receiver. A monaural signal (M) is applied as the input signal for a transfer function circuit of the form H(s), which modulates the intensity of the monaural signal as a function of frequency. The intensity modulated H(s) signal is coupled to a reproducing loudspeaker, and comprises one channel (B) of the synthetic stereo system. The H(s) signal Is also coupled to one input of a differential amplifier (40). The monaural signal (M) is coupled to the other input of the differential amplifier (40) to produce a difference signal (M-H(s)) which Is the complement of the H(s) signal. The difference signal is coupled to a second reproducing loudspeaker, which comprises the second channel (C) of the synthetic stereo system. When the stereo synthesizer Is utilized as the sound reproducing system of a television receiver, the reproducing loudspeakers are located at opposite sides of the kinescope. The amplitude-vs-frequency response curves of the two output channels (B, C) are selected to have crossover points at which the amplitudes of the two response curves are equal, which effectively centers sounds at these frequencies between the loudspeakers. One crossover frequency is chosen to occur at approximately the frequency of peak intensity of the human voice, another to occur at the center frequency of the second (articulation) formant frequencies of the human voice so as to effectively center voices on the kinescope while preserving the ambience effect of other, more randomly distributed sound signals. Centering the second formant frequencies also provides increased quality in the reproduction of speech sounds.

Abstract: Appareil de transport a vibration (10) par excitation du bati. Un probleme pose par les transporteuses de l'art anterieur est le fait qu'elles sont soumises a un mouvement de basculement et ne peuvent fonctionner de maniere efficace sur une grande distance de chargement. Ces problemes sont resolus avec l'appareil (10) ayant un organe de transport allonge (30) monte au moyen de poutres-ressorts (56, 57) sur un bati excite (14). Le bati excite (14) possede des moyens d'entrainement vibratoire equilibres (70) pour faire vibrer le bati excite (14) suivant une ligne de force (76) qui passe par le centre de gravite de l'appareil et, de preference par le centre de gravite (95) de l'organe de transport (90) et du bati excite (93). Le rapport entre le poids de l'organe de transport et le poids du bati excite devrait etre de 1,5 a 3,5 et de preference entre 2,5 et 3,5. Un tel dispositif assure une transmission minimum des vibrations a la fois horizontales et verticales dans la structure de support stationnaire et reduit au minimum le mouvement de bascule et permet a l'appareil de fonctionner de maniere efficace sur une grande distance de chargement.

Abstract: Electronic signature and message verification is obtained using a central vault which is a physically secured Authenticator designed as a hardware automaton not under control of any operating system. All secure electronic signature verification transactions between terminals (users at stations A and B) are transacted through the vault. The vault and all terminals include an identical key-controlled block-ciper cryptographic facility wherein each user at a terminal has access only to his own key and wherein the vault has access to all user keys. User A first sends to the vault a message comprising a clear first part and an encrypted second part. The vault obtains A's key from the clear first part and decrypts the second part. The vault transmits to user B all encrypted under B's key, the encrypted second part and the decrypted second part, and user B performs a decryption using his key, and stores said encrypted second part. User B then initiates an equivalent return message procedure to user A via the vault. At the end of a transaction, user A and user B each have uniquely encrypted messages which can be utilized in later arbitration proceedings wherein user A cannot later deny having sent a message or its content and similarly user B cannot deny having received the message or its specific content.
