Abstract: The present invention relates to an in­organically insulated heater of a long life for use in air flow sensors, cathode ray tube cathode heaters etc., wherein the distribution of inorganic insulating particles of the whole insulating layer is made uniform and thereby the development of cracks and the like in the insulating layer is reduced and breaking of wire and dielectric breakdown occur with difficulty even at high temperatures and under strong vibrations.

Abstract: A parallel branched N-state design method is used for discrete increment signal processing systems, such as incremental phase shifters and attenuators. These systems are implemented using parallel branched signal processing networks, each with N parallel discrete increment branch circuits (i.e., without being restricted to binary-state networks). In comparison with conventional cascaded binary-state networks, the parallel branched N-state design achieves reduced complexity and insertion loss. An exemplary embodiment of a phase shift system providing 32 phase increments (or states) uses three cascaded phase shift networks -- two quaternary-state networks (Quits 10, 20) and a single binary-state network (Bit 30). The most significant Quit (10) illustrates the N-state design, providing the four most significant phase states (reference, +90°, -180°, -90°) using four switched-line branch circuits (100, 200, 300, 400), each controlled by two PIN diode control elements (D1A/D1B, D2A/D2B, D3A/D3B, D4A/D4B). A parallel branched N-state design for discrete increment systems minimizes insertion loss and complexity by minimizing the total number of cascaded networks, the total number of cascaded branch circuits and the total number of branch control elements.

Abstract: An electro-optic mirror of the type having an electro-optic cell or medium with a transmittance which is variable upon the application of an electric field includes a perimeter coating (16) applied to a front or rear surface of a substrate element for concealing any seal and/or electrical connections for the electro-optic cell or medium. The perimeter coating (16) may be reflective to increase the field of view in the mirror and allow use of smaller cases or retaining bezels. Alternately, the perimeter coating may be opaque and nonreflective such as black frit, paint or lacquer. In either case, the coating may also be electrically conductive to substantially encircle an electrically conductive layer on the substrate and evenly distribute electric current to the electro-optic cell or medium for enhanced colouration response. The perimeter coating may be used with either a single, optically transparent mirror substrate including solid-state electro-optic cell or a laminate mirror assembly including spaced, optically transparent substrates with an electro-optic medium confined therebetween. The laminate assembly may include a seal between the substrate elements which is either dark or colour matched to the surrounding rim/bezel providing a border of uniform colour around the assembly perimeter.

Abstract: In order for on-line colour measurements on continuously moving fibre slivers to deliver reasonable and reproducible measured values, the fibre slivers must be compressed when they pass the measuring point at which the colour measurement is carried out with the aid of a colour measuring device available on the market. In accordance with the method according to the invention, the measuring point is chosen as a processing point at which the fibre sliver is compressed as required by the process and is of sufficient layer thickness.

Abstract: Self-testing of a read only memory (10') containing an m x n+1 array of single-bit storage cells (12') is accomplished by first loading the bits of a preselected quotient string into the n+1 column of the memory. Thereafter, a first polynomial division is performed on the entire contents of the memory by sequentially shifting out of the bits in the cells in each successive ROM row in a right-to-left direction into a separate one of the n+1 inputs of a bidirectional multiple input shift register (18'). A second polynomial division is then performed on the m x n contents of the memory (10') by sequentially shifting the bits out of each successive row into the shift register (18') in a left-to-right direction. As each row of bits is shifted into the shift register (18') during the second polynomial division, the register generates a quotient bit which is exclusively OR'd with a separate one of the quotient bits stored in the  n +1   th    column of the memory, allowing for errors in the memory to be detected. At the conclusion of the second polynomial division, there remains in the register a residue, also indicative of the errors in the memory.

Abstract: Memory means (30) according to the invention converts to data form and stores the chorus patterns obtained by breaking down and organizing the backing chorus for a particular piece of music into appropriate segments. Thus, when reproducing a piece of music created in accordance with the MIDI standard, all the chorus data corresponding to said piece of music can read from said memory means (30) and synchronized with the music reproduction data, after which appropriate chorus patterns can be selected one by one and mixed into the music. The invention thus enables the requisite memory capacity to be kept to a minimum while at the same time enabling not only the reproduction of original sounds from music data created in accordance with the MIDI standard but also the reproduction of a natural backing chorus sound created from data based not on the MIDI standard but obtained directly from natural human voices.

Abstract: A network arrangement and control method where, before any transmission of data occurs for a particular communication, a network controller determines an unused path to provide a connection, advantageously all the way through the network from a given inlet to a given outlet. Once the identity of the unused path is known, the controller determines control information for use in activating that path and transmits that control information into the network, significantly via the network inlets. The network responds by activating the determined path and communication is enabled via the activated path, but only for the single connection and no buffering of information is required within the network. The network is particularly well suited for optical implementation and control is effected without the use of spatial light modulators but rather by means of control elements embedded within the network itself.

Abstract: A process for preparing a high molecular weight organopolysiloxane comprising: a first polymerization step of bringing a low molecular weight organopolysiloxane into reaction in the presence of a quaternary phosphonium hydroxide compound and/or a silanolate thereof as a catalyst under heating; and a second polymerization step for bringing the resulting reaction mixture into reaction in the presence of an alkali metal hydroxide and/or a silanolate thereof as a catalyst under heating. According to the process, a high molecular weight organopolysiloxane can be prepared using a reduced amount of catalyst for polymerization reaction, so that the amount of salts formed from a neutralizing agent is smaller and the subsequent filtration step for purification is less burdensome and easier to carry out. Further, it is possible to obtain high molecular weight organopolysiloxanes of excellent qualities as to transparency, electrical insulation property, arrangement of structural units in the case of preparation of copolymer, and odor.

Abstract: A ferroelectric liquid crystal device is constituted by disposing a ferroelectric liquid crystal between a pair of substrates having thereon electrodes for voltage application and provided with uniaxial alignment axes, as by rubbing, so as to provide a high pretilt angle of at least 10 degrees. A problematic liquid crystal movement in such a high-pretilt angle ferroelectric liquid crystal device is suppressed by improving a smectic layer structure therein, inclusive of a symmetry of pretilt angles at the pair of substrate boundary surfaces. Such an improved smectic layer structure is accomplished by a realigning treatment after cooling to the chiral smectic phase or in the final stage of the cooling to the chiral smectic phase as by application of an AC electric field and/or by repetitive heating-cooling in the chiral smectic phase. The improved smectic layer structure is represented by, e.g., an X-ray diffraction peak having an increased peak area and/or a decreased half-value width.
