Abstract: An input/output multiplexer 20 couples a central subsystem 3 to peripheral subsystems 4 containing several units. Information flows from the central subsystem to the peripheral subsystems through a central subsystem data distributor 21, a switch 25, and a peripheral subsystems access controller 26; and in the reverse direction through a peripheral subsystems data controller 27, a channel service processor 28, a switch 29, and a central subsystem access controller 20. Information relating to different subsystems can be at different stages in its passage simultaneously. A control word processor 24 and scratch pad memory 31 stores files from the central subsystem and prepares real addresses, and the channel service processor 28 obtains these addresses, in response to signals from the peripheral subsystems, and incorporates them in the information flowing to the central subsystem.

IPC: H01L21/761

Abstract: When fabricating semiconductor devices from a larger slice of semiconductor material, it is sometimes necessary to produce a region of dopant impurity in which the region extends right through the slice from one major face (7) to the opposite major face (4). Such a region is produced over localised defined areas of the slice and often they correspond to the boundaries of individual devices along which the slice is subsequently cut to produce a number of physically separate devices. A deep but narrow recess (6) is initially formed in one face of the slice and the appropriate impurity is diffused into the surface of the recess and the opposite unrecessed face until the two diffusions meet.

Abstract: The operating condition and/or characteristics of a battery is tested by obtaining the dynamic voltage-current characteristic of the battery as a function of the charge condition thereof. A controllably varying charging current is supplied to the battery, and the voltage produced across the battery while that current is supplied is measured. The dynamic voltage-current characteristic is obtained as a function of the measured voltage and supplied current. This voltage-current characteristic is compared to predetermined voltage-current characteristics representing batteries of the type being tested in order to determine the operating condition and/or characteristics of the battery under test.

The coupling holes contain resonators forming a short-circuit for the higher band frequencies. The common guide contains, viewed from the antenna coupling input, between the first and second coupling holes, a first filter which reflects towards the first coupling holes the waves in the lower band and having the polarization of the wave passing through the first hole and, between the second coupling hole and the junction, a second filter which reflects towards the second coupling hole the waves located in the lower band and having the polarization of the wave to pass through the second hole.
