Abstract: An optical switch has waveguides (25-1,25-2,25-3,25-4) on a semiconductor substrate (21). The waveguides intersect at rhomboidal regions (27-1, 27-2, 27-3, 27-4) and stripe layers (22, 23) are formed along the longer diagonal of the rhomboidal regions. The carrier concentration of these stripe layers (22, 23) may be changed, by applying an appropriate voltage to electrodes (24-1, 24-2, 24-3, 24-4, 31) and this causes a change in the refraction index of the stripe layers (22, 23) and so causes reflection of light propagating in one waveguide into another waveguide. The substrate (21), the waveguides (25-1, 25-2, 25-3, 25-4), and the stripe layers (22, 23) are each a compound semiconductor of the same semiconductor system, and the band gap of the stripe layers (22, 23) is equal or close to the wavelength of the light to be switched. Such an arrangement permits a relatively large angle between the intersecting waveguides (25-1, 25-2, 25-3, 25-4) and so permits the optical switch to be small.

Abstract: An error correcting encoding method and a vehicle data communication apparatus based on the same for use in data communication via fading communication channels dominated by burst errors in the data communication among vehicles such as automobiles are disclosed. The error correction encoding method detects, as data sent from a transmitting side is received by a receiving side, any error contained in the received data as a frame error rate of error frames involved in block data or a bit error rate of error bits involved in the block data and selects an error correcting code in response to the frame error rate for encoding. The vehicle data communication apparatus according to the present invention profitably employs the method, and changes an error correcting code to be used on the transmitting side in response to the extent of errors involved in the received data detected by the receiving side of a remote apparatus.

     The ink composition of the invention evidences minimal crusting and reduced evaporation loss of water. The solubility of anionic dyes is increased in the acidic medium over that otherwise obtainable, due to the presence of the alkanol ammonium compound or amide. The ink composition of the invention is suitably employed in any of the ink-jet printers commonly in use.

Abstract: A multiplexer for use in a digital subscriber controller having a number of analog ports and digital ports which can be programmed via an external microprocessor to establish time-division multiplexed bidirectional data paths between three subscriber-selected ports designated as "sources" and three subscriber-selected ports designated as "destinations". Among the ports is a line-interface port having two kilobit-per- second channels on which analog/digital data is received from and transmitted onto the network transmission line. Among the digital ports is a three-channel serial port and a two-channel microprocessor interface port. An analog port is also provided at which a variety of audio transducers may be connected. The data-routing multiplexer consists of three sections, each comprising a plurality of registers connected to a single internal bus on which time-division-multiplexed signals are generated and received by particular subscriber-selected registers, each register within a section serving as either a generator or a receiver for the internal bus for a particular digital channel. An extension of the internal bus is connected to the analog port. A set of three control registers stores the subscriber-selected sources and destinations. Control signals are generated therefrom which affect the subscriber-selected interconnection of registers within the data-routing multiplexer with the internal bus. The multiplexer facilitates maintenance and testing of the digital subscriber controller by permitting a loopback path to be established for a device connected to a port by simply designating a path having that port as both its source and destination.
