Patent EP-0168678-A2 (EP)
Inventor: COTTRELL PETER EDWIN
IPC: H01L27/02
Filed: 1985-06-24
Abstract: The overvoltage protection circuit, when used with CMOS circuits, protects them from overvoltage conditions while minimizing latch-up conditions in the structure. It consists of a well region (16) of an opposite conductivity to that of the substrate (10, 12) defining a pocket region (18) having a conductivity type which is similar to that of the substrate (10, 12). A first PN junction diode (34) is formed in a portion of the well region (16) and a second PN junction diode (32) is formed in the pocket region (18). The two diodes have opposite polarity and they both are connected to a signal line in such a way that one of the two diodes will be forward biased if the voltage on the signal line exceeds the bounds of the power supply voltages. The pocket region (18) is connected to a V ss  terminal which is normally grounded and the well region (16) is connected to a power supply V oo . The doping concentration in the well region (16) is predetermined to have a gradient so that minority carriers injected from one of the diodes in the well region will be repulsed and prevented from moving into the substrate region where they would be majority carriers and they could cause latch-up in the structure or at the very least adversely affect the voltage level of the substrate. Instead the injected carriers recombine in the well region (16) or are collected by the adjacent isolated pocket region (18). When the second diode (32) is forward biased, the minority carriers are injected into the isolated pocket region (18) and are prevented from reaching the substrate (10) by the underlying well region (14). This prevents these carriers from affecting the operation of adjacent circuits.

Abstract: The present invention provides a process for the production of nitrogen at relatively high yield and purity by cryogenic rectifiction of feed air characterized by
 (1) introducing the major portion of the feed air into a rectification column which is operating at a pressure in the range of from 241 to 1000 kPa (from 35 to 145 psia), and wherein feed air is separated into nitrogen-rich vapour and oxygen-enriched liquid;
 (2) condensing a minor portion of the feed air, at a pressure greater than that at which the column is operating. by indirect heat exchange with oxygen-enriched liquid;
 (3) introducing the resulting condensed minor portion of the feed air into the column at a point at least one tray above the point where the major portion of the feed air is introduced into the column;
 (4) condensing a first portion of the nitrogen-rich vapour by indirect heat exchange with vapourizing oxygen-enriched liquid;
 (5) passing at least some of the resulting condensed nitrogen-rich portion to the column at a point at least one tray above the point where the minor portion of the feed air is introduced into the column; and

Abstract: An improved ECL circuit in which reference voltages have been eliminated is provided. The base of the reference switching transistor which is usually connected to a reference voltage is instead connected to the emitter of an emitter follower transistor coupled to the input switching transistor. The need for a reference voltage is thus eliminated because the emitter of such emitter follower transistor, and thus the base of the reference switching transistor, will be at the opposite level of the input to the base of the input switching transistor.

Abstract: A high reliability low cost connector has flat retain, connection and contact members blanked from an electrically conductive sheet metal and inserted into openings in an electrically insulating body. Each retainer has a post at one end extending from an opening at one side of the body and has a pair 6f integral wings spaced from each other in a plane at its opposite end disposed in the opening at the opposite side of the body. Spring clips are blanked and formed from an electrically conductive sheet metal spring material and are inserted into the body openings so loop portions of the clips fit between the pairs of retainer wings in each opening and are biased into resilient electrial engagement with the retainer wings. Each clip preferably has two pairs of juxtaposed spring leaves integral with the loop spaced at 90° relative to each other around a common axis to grip a terminal inserted between the spring leaves. The loops are also formed with interruptions in each loop in an intermediate location between two adjacent spring leaves. The sheet metal retainers and clips are inserted into the body openings while suspended from support strips left during the blanking steps and are then separated from the support strips. In that way the retainers and clips have predetermined uniform orientations in the openings.

Each of the RF carrier, modulation and gate signals may be individually buffered and/or amplified prior to use of that signal in one of the modulation or gate processes. The modulated RF carrier signal and/or the gated RF signal may also be buffered and/or amplified prior to being respect i vely gated in, or output from, the apparatus. Each of the buffer-amplifiers, except the gate signal buffer-amplifier, may itself be gated responsive to the gate signal, to provide a desired degree of apparatus output signal on-off ratio.

Abstract: Adjunct virtual machines are disclosed that are connected to an existing base virtual machine to provide for the creation of service processors each providing a service to the base virtual machine. All communication with the user takes place through one console that is shared by the base virtual machine and its adjunct virtual machine. That is, all messages and responses between the base virtual machine and the adjunct virtual machines are directed to only one console such that each adjunct machine does not require its own separate console. Even though only one console is used, there is no requirement for one machine to log off while an operating system control program (SCP) function is executing in the other machine. As a result, implementation of the adjunct virtual machine permits the construction of host SCP console functions that have sustaining dialogs with the user while all other SCP functions are available to the user during the dialog. A single directory is used to define the architecture of the adjunct virtual machine which can be used, as a prototype, by all base virtual machines. The adjunct machine gains control when it is dispatched with a suitable program status word.
