    Abstract: A mobile telecommunications system allows the set up of flexible groups within defined locations e.g. an area covered by a cell having a base station. When a mobile station MS enters the location and attempts registration, it is assigned a location specific group identification code 308, which is transmitted and received 310 by the MS. The mobile station stores the code in its scan list and thereafter monitors the appropriate signalling channel for the presence of the code as part of a paging address. On receipt of the code 314 the MS is enabled to join the location specific group call 318. The invention allows the setting up of groups within specified areas, without the use of area defining fields in the communications protocol, these not being standardised amongst different providers. Further the setting up of the groups does not require expensive reprogramming of the mobile stations on changing groups. The invention can be applied to TETRA, UMTS or other third generation communication systems. The mobile units may be any kind of radio device, e.g. mobile phone, PDA or wireless connected computers.

    Abstract: PROBLEM TO BE SOLVED: To provide a method of mitigating errors in a distributed speech recognition process. SOLUTION: When one or more speech recognition parameters in a specified vector group are replaced by each replacement parameter which is determined by referring to one or more speech recognition parameters from a vector received after the specified vector group, possibility for permitting latency in the speech recognition process is advantageously utilized.

    Abstract: PROBLEM TO BE SOLVED: To provide a new bit coding system for serial communication which can overcome the problems such as the internal synchronization of a distributed system architecture and the EMI emission and also can make the best use of bands. SOLUTION: This bit coding system includes a carrier generator 100 which is used together with a bus 7 of the distributed controller networks (200 and 300) and produces a substantially sine wave-like waveform. The modulation mechanisms (340 and 341) function to modulate the waveform amplitude between the 1st and 2nd amplitudes and to define the 1st and 2nd data value. Then the timing information on the bus 7 is defined by means of the zero crossing point of the waveform.

    Abstract: PROBLEM TO BE SOLVED: To provide improved antenna array weight by controlling a transmitter and adjusting weight related to an antenna in accordance with weight information received from the other communication equipment. SOLUTION: The output of the transmitter 122 is connected to transmission route weight circuits 131, 133 and 135 and the transmission route weight circuits 131, 133 and 135 are connected to one of the antennas 106, 110 and 112 through a duplex circuit 113. The transmission route weight circuits 131, 133 and 135 weight signals outputted by the transmitter 122 in accordance with a control signal received from a controller 126. The signals outputted by the transmitter 122 can be connected to the transmission route weight circuits 131, 133 and 135 by respective conductors or lines and therefore they can respectively receive the signals or they can be connected by the common conductor or line. Thus, the transmission route weight circuits 131, 133 and 135 can receive the same signals.

    Abstract: PURPOSE: To provide a radio receiver consisting of first and second antennas, which are spatially separated from each other and perform diversity, and an equalizer which synthesizes components of reception signals separated temporally. CONSTITUTION: Signals received by first and second antennas 10 and 11 are synthesized by a synthesizer 19 and are connected to the equalizer. A variable delay means 18 is provided on the reception line of one of antennas, and the signal received by this antenna is delayed behind the signal received by the other antenna. Thus, a possibility of destructive interference between signals from first and second antennas is considerably reduced.

    Abstract: PURPOSE: To prevent remaining aluminum form being stained after photoresist is removed in an asher by etching a resist in an oxygen gas plasma at 9 specific temperature. CONSTITUTION: This photoresist 20 is removed from a metallic layer 16, which is formed on a substrate 10 and has a pattern prescribed with a corrosive gas plasma. In this case, the resist 20 is etched in the oxygen glass plasma for a certain time at a temperature which is high enough to remove all the remaining corrosive gas absorbed into the photoresist 20 and lower than the temperature at which a metal 16 begins to reflow. For example, a thin film 14 of titanium nitride, a layer 16 of aluminum, and a layer 18 of titanium nitride which are formed on a oxide layer 12 on a silicon substrate 10 are etched in a chlorine gas plasma, by using the photoresist 20 as a mask. Then etching is carried on in an oxygen plasma at 300 deg.C for three minutes, to remove the resist 20.
