Patent GB-2250160-A (GB)
Title: Device for changing over and restoring automatically telephone circuit
Inventor: IWAI SEIZO
IPC: H04M1/00
Filed: 1992-01-02
Abstract: A communication by an auxiliary terminal (AUX) is performed using a voice signal line taken out by a switch (SW) having eight circuits and six contacts or having eight circuits and three contacts. Then, an automatic changing over circuit (SS) which is isolated from the voice signal line in relation to DC and is coupled to it in relation to AC detects the completion of the communication and the restoring connection is performed. By this configuration, communication can be performed by connecting the auxiliary terminal with an exchange called an energy-saving type and outputting only AC signals, and the restoring connection can be performed automatically after the completion of the communication. That is, the device for changing over and restoring automatically a telephone circuit whose application is not limited can be provided. <IMAGE>
Patent GB-2263795-A (GB)
Title: Interrupt priority using timer circuit.
Inventor: NAKAYAMA MAKOTO
IPC: G06F13/26
Filed: 1992-01-15
Abstract: Interrupts which are generated simultaneously in any of a plurality of peripheral units are prioritised according to different time periods which reflect the priority of the units. When two or more units initiate interrupt actions simultaneously, a bussed interrupt control line is pulled low and a timer in each of the competing units is released. While this interrupt control line is held low, the timers in each of the other peripheral units are held at zero, preventing later interrupts (regardless of priority) from joining the race. As each timer times out in turn, the respective unit interrupts the main processor using the interrupt request line, and in so doing, halts the timers in the remaining units. <IMAGE>

Title: Control system including a switching circuit for ensuring proper operation when operating power is removed from a portion of the control system
Inventor: LENDARO JEFFERY BASIL
IPC: H03G3/34
Filed: 1992-05-01
Abstract: An arrangement for ensuring that a proper control level for a controlled unit is maintained when a supply voltage is removed from a control unit of a control system includes a switching circuit (Q3) coupled between the control unit (100) and the controlled unit (400). Q3 couples the control signal generated by the control unit (100) to the controlled unit (400) when the supply voltage is present and is responsive to the absence of the supply voltage for decoupling the output of the controlling unit (100) from the input of the controlled unit (400). In this manner, a current path established by a protection circuit within the control unit (100) when the supply voltage is removed is decoupled from the controlled unit (400) and does not adversely affect the operation of the controlled unit (400). The application to muting in a standby/run arrangement is described. <IMAGE>

Patent GB-2285337-A (GB)
Title: Manufacture of semiconductor device with aluminium wiring
Inventor: ABE YASUSHIGE
IPC: C23C14/18
Filed: 1994-12-23
Abstract: A strong tendency of exhibiting the (1 1 1) plane appears in an Al film sputtered on a substrate surface without heating the substrate intentionally, although the size of Al grains is small. Thereafter, in the midst of Al film deposition, the substrate is heated while continuing formation of the Al film. With this later process, the size of Al grains increases while inheriting the strong tendency of orientating the (1 1 1) plane, and a resistance to electromigration is improved. The Al film is patterned by using chlorine-based gas etchant and then heated in vacuum so that residual chlorine can be vaporized. Alternatively, the Al film is processed by silver nitrate or lead nitrate solution so that residual chlorine can be changed to inactive substrate which is soluble to ammonium hydroxide. The method is particularly applicable to making a DRAM wiring pattern 20, 23. <IMAGE>

Title: Monitoring of multiple-electrode gas sensors
Inventor: WILLIAMS DAVID EDWARD
IPC: G01N33/00
Filed: 1994-08-05
Abstract: A gas sensor, suitable for use under non-steady state conditions, has a gas-sensitive resistor (18) with pairs (N, W) of electrodes which either have different spacings between the electrodes of a pair, or comprise a pair at the active surface and further pairs buried in the resistor at different distances from the active surface. The sensor can be used in place of a sensor array, and is coupled to means for processing the resistance signals to detect and/or measure at least one target gas. The sensor is self-diagnostic, and factors such as relative humidity and ambient oxygen, that can otherwise affect the readings, can be compensated for without the aid of additional sensors for that purpose. An operating line or surface ((a), (b)) is defined for the expected behaviour of the sensor, and the resistance signals from the electrode pairs are processed so as to give information which is then related to the operating line or surface, so as to reveal, in terms of error indications, any malfunction of the sensor for the presence of specific constituents of the gas mixture. <IMAGE>
