Abstract: An information transmitting system capable of two way communication, suitable for use in transmitting information signals between a central control unit (100, 200) and a plurality of terminal apparatus units (35). Each terminal apparatus unit (35) may be located at a different passenger seat in an aircraft, a train, a bus, or the like. The signals transmitted from each terminal apparatus unit (35) to the central control unit (100, 200) are transmitted by way of two channels via a respective transmitter (38) and a cable (21). In one operating mode, one channel is used as a random access channel, and the other is used as a polling channel. When polling transmission is not being effected, the polling channel is used as a second random access channel, so that the system may efficiently transmit a maximum number of information signals on two random access channels.

Title: Large taper machining method using wire electric discharge machine
IPC: B23H7/08
Filed: 1988-09-28
Granted: 1992-08-19
Abstract: This invention provides a large taper machining method using a wire electric discharge machine which can carry out a large taper machining for a taper angle of 20° or larger stably and with high accuracy and can also improve surface smoothness of the workpiece. When electric discharge machining including machining of a large taper with a taper angle of 20° or larger is executed, a wire electrode (5) consisting of a soft electrode wire for discharge machining having a tensile strength of up to 46 kg/mm2 is used. The wire electrode bent greatly at wire support portions of upper and lower wire guides (8, 12) is thereafter easily transformed into a straight line and forms a linear portion between both wire guides, thereby stabilizing machinability and improving machining accuracy and surface smoothness of the workpiece.

Patent EP-0334192-B1 (EP)
IPC: H04J14/00
Filed: 1989-03-15
Granted: 1992-09-02
Abstract: In fibre-optical transmission in duplex mode using the same wavelength in forward and backward direction, the problem arises that, if an interruption occurs in the transmission path, the transmitter's own transmitted signal appears as a result of reflection in its own receiving element and deceives monitoring circuits provided. To ensure monitoring reliability, the digital signal to be transmitted is converted according to the invention before transmission into a redundant code and at the same time specific code errors which can be detected at the receiving end are inserted at periodic time intervals. In both terminal stations, the received signal is monitored for the occurrence of the specific code errors and an alarm signal is generated if they occur in the receiving element of the transmitting terminal station. <IMAGE>

Abstract: Electro-optical components and semi-manufactured articles, and method for making them. A light conducting layer is formed from a poleable or poled glassy polymer material, which has an under ionizing radiation definitively destructible e/o activity. A selective irradiation under a parallel beam will give sharp transitions (C, D) from an e/o active area (2. 1) or an area which can still be activated to an e/o non-active area. The buffer layers (3 and 5) can also consist of suchlike irradiated material. A suitable positioning of the electrodes (4 and 11) between which by means of a difference in voltage applied across the connections (12 and 13) an electric field with a sufficient intensity and/or uniformity can be induced extending into the border area, on both sides of the transition planes (C, D), will make sharp inducible refractive index transitions possible. This is utilized with e/o inducible waveguides in thin layers to obtain sharp lateral definitions, and in an optical intermediate switch.
