摘要： An electronic assembly has a substrate with several conductive tracks and with a switching matrix within the thickness of the substrate. Several groups of identical integrated circuits are mounted on the substrate, one circuit from each group being operatively connected into the assembly by the switching matrix. A processor detects malfunction of a circuit and controls the switching matrix to disconnect that circuit and operatively connect into the assembly an alternative circuit from the same group.

摘要： An integrated circuit substrate is made by exposing a mask to a composite representation of the pattern of integration of several different dice. The mask is exposed several times to produce several composite representations on the mask. Several different composite representations may be formed on the same mask. Identical aligned composite representations are checked by optically comparing corresponding dice in different composite representations via respective optical systems. The several composite representations on the mask are transferred simultaneously to the substrate to reproduce the pattern of integration of the dice at a plurality of locations in the substrate. The area of the mask covered by the composite representations may be greater than the usable area of the substrate such that for at least two of the composite representations only a portion of the composite representations is reproduced on the substrate, some of those dice not reproduced in one of the composite representations being reproduced in the other of the two composite representations. One half of the mask may have composite representations relating to one processing step, while the other half of the mask relates to a different processing step, the mask being reoriented after the first step so that the part of the substrate exposed initially to the one half of the mask is subsequently exposed to the other half of the mask, the other part of the substrate being rejected.

摘要翻译： 通过将掩模曝光到几个不同骰子的集成图案的复合表示来制造集成电路基板。 掩模曝光数次以在掩模上产生几个复合表示。 可以在相同的掩模上形成几个不同的复合表示。 通过相应的光学系统通过光学比较不同复合表示中的相应骰子来检查相同对准的复合表示。 掩模上的几个复合表示被同时传送到衬底，以在衬底中的多个位置处再现骰子的集成模式。 由复合表示覆盖的掩模的面积可以大于衬底的可用面积，使得对于复合表示中的至少两个，复合表示中仅一部分复合表示在衬底上再现，这些裸片中的一些不被再现 复合表示之一被复制在两个复合表示中的另一个中。 掩模的一半可以具有与一个处理步骤相关的复合表示，而掩模的另一半涉及不同的处理步骤，该掩模在第一步骤之后被重新定向，使得该基板的一部分最初暴露于一半 的掩模随后暴露于掩模的另一半，衬底的另一部分被拒绝。

摘要： An electrical indicator has a consecutive series of light-emitting diodes which are arranged along a straight or curved reference scale. A limited region of the series, comprising several diodes, is energized and this illuminated region is displaced along the scale upon change in an electrical input variable supplied to the indicator such that the position of the region provides an analogue indication of the value of the input variable. To improve the appearance of the display and reduce power consumption, the brightness of the region varies along its length with one or both of the outermost diodes being energized at lower levels than another of the diodes. The indicator may include a shift register having a number of storage locations, each for storing signals representative of a corresponding one of the light-emitting diodes, the signals at these locations being displaced in accordance with change in value of the input variable. Signals output from each storage location of the shift register are supplied to a gate which controls switching of a transistor that is connected in series with a resistor in the energizing circuit of each light-emitting diode. Each energizing circuit includes two such transistors and associated gates which control the degree of brightening of each light-emitting diode by switching one or more resistors in parallel in the circuit. The gates are connected to control brightening of one diode in accordance with brightening of one or more other diodes.

摘要： A control system for a gas-turbine engine has two parallel control units, either one of which can be switched to supply control signals to the engine in response to input signals, such as from the pilot's control lever and from various sensors. Each unit has a limiter that limits the fuel supply to the engine if the engine speed approaches or exceeds a predetermined maximum. A monitor unit in each control unit detects when the limiter has assumed control of the engine for more than a predetermined time, and switches the system to control by the other control unit. The predetermined engine speed may be different for different settings of the pilot's control lever. The monitor unit in such an arrangement, may receive signals in respect of the acceleration and deceleration of the engine and switch to the other control unit only when the speed is outside the predetermined speed for the pilot lever setting, and when the acceleration or deceleration is not such as to bring the speed back within the predetermined speed.

摘要： A hydraulic control system has two fluid supply circuits which control fluid pressure supplied to respective chambers of a fluid-controlled actuator, each chamber having an individual piston mounted on a common actuator rod. In normal operation, a major part of the pressure is supplied to the actuator by the first circuit in accordance with control signals derived from an external source. The second circuit supplies pressure to its respective chamber at a lower level in accordance with control signals derived from the differential pressure across the piston in that chamber, the pressure supplied by the second circuit acting to reduce the differential pressure across the piston. The system also includes a control unit that responds to malfunction of the first circuit or error in the control signals supplied to the first circuit, by disconnecting the first control circuit from control of the actuator, such as by equalizing pressure across the piston in the first chamber. Upon detection of a malfunction or error, the control unit also supplies to the second circuit, instead of the signals derived from the differential pressure, control signals nominally-identical to the control signals supplied to the first circuit and derived from an external source. In this way, following detection of a malfunction in the first circuit, the second circuit controls the major part of the pressure supplied to the actuator.
