Abstract: The invention relates to a method and to apparatus for manufacturing a plurality of mutually similar objects or assemblies, where each assembly comprises at least two mutually coacting elements of mutually different types or configurations and each having a respective critical dimension which is determinative of the function and/or the quality of the coaction between the elements. Accord­ing to the invention, a manufacturing device (1) for manufacturing a first type of element of the mutually coacting elements is provided with a measuring device (3) for measuring the critical dimension of each individual first type of element. A manufacturing device (2) for manufacturing a second type of element of the mutually coacting elements is provided with a measuring device (4) for measuring the critical dimension of each individual second type of element. The measured values for each individual element of both types are stored in a data storage device (5) together with information concerning the identify of the element. An element assembling device (8) is connected to the data storage device (5), which on the basis of information stored therein controls the assembly device (8) in a manner to select and assemble those elements which will fulfil optimally a predetermined criterium with respect to the function and/or the quality of the coaction between the elements.

Abstract: The circuit comprises a tank capacitance (C) and a charge circuit supplied with the same voltage (Vs) as the bridge (M1, M2) and comprising an inductance (L) and a control transistor (T). There is also provided a control circuit (CC), which comprises an oscillator (OSC) controlling the periodic switching of control transistor (T) and a comparator (CP1) which controls the momentary clamping of control transistor (T) in the condition wherein the charge circuit is interrupted when the difference between the voltage across capacitance (C) and the power supply voltage exceeds a preset maximum value and the unclamping of the same transistor (T) when such difference falls below a preset minimum value. A further comparator (CP2) similarly clamps control transistor (T) if there is an excess current in the transistor itself. 
     The generated voltage (Vp), which is higher than the supply voltage (Vs), controls, through a driver circuit (DS2), the gate of a power MOS transistor (M2).

Abstract: The invention relates to a control system which controls the diameter of a turbine shroud which surrounds a turbine in a gas turbine aircraft engine. The invention seeks to minimize the clearance (33) between the turbine rotor blades (123) and the shroud (36). Air is bled from the compressor (18) in the engine and ducted (98,112) to the shroud in order to heat or cool the shroud in order to, respectively, either expand or shrink the shroud to a proper diameter. The air temperature which is required is computed based on compressor speed and other engine parameters, but not necessarily upon rotor temperature as such, despite the fact that rotor temperature has a significant influence upon rotor diameter, and thus upon the shroud diameter needed. In a preferred embodiment, air at two different temperatures is bled from two different compressor stages (83,89) in the engine and mixed together (98) in a ratio which is determined (by valve 94) according to flight conditions, in order to provide air of the required temperature for the shroud, and then ducted to the shroud in order to modify shroud size. Further, during accelerations and decelerations of the engine, a different air temperature is provided, as compared with that provided during steady state operation. In the event of system failure shroud diameter can be controlled by back up systems, e.g. one for use during steady state, and the other for use during accelerations and decelerations.

Abstract: A bipolar transistor has a base region comprising a graft base region (11), a linking base region (13) and an intrinsic base region (12). A diffusion suppressing region (15) of an opposite conductivity type to that of the base region (11, 12, 13) is formed at least at the lower portion of the intrinsic base region (12). The junction depth (J2) of the linking base region (13) is selected to be shallower than that (J4) of the intrinsic base region (12). Since the base to base linking is performed in the linking base region (13), collision between the intrinsic base region (12) and the graft base region (11) is inhibited, while the diffusion of the base width beyond the diffusion suppressing region (15) is also inhibited. The junction depth (J2) of the linking base region (13) is selected to be shallow to prevent the width of the parasitic base from being increased to suppress the side injection effect.

Abstract: The invention relates to a method for neutralizing a sulfuric acid solution containing predominantly Zn ion. In the method of the invention at least one compound selected from chlorine-containing compounds of Na ion, K ion, Mg ion, Ca ion, and NH₄ ion in an amount at least chemically equivalent to SO₄ ion contained in the solution is added to the sulfuric acid solution. Then the sulfuric acid solution is brought into contact with an organic solvent composed of one or more species selected from oxygen-containing organic solvents and alkylamine organic solvents to extract Zn ion from the sulfuric acid solution as a chloride complex to the organic solvent. The sulfuric acid solution after extraction of Zn ion may be further treated by addition of an oxidizing agent or by an electrochemical means to convert Fe²⁺ into Fe³⁺ ion and brought into contact with a second organic solvent (B) composed of one or more species selected from oxygen-containing organic solvents and alkylamine organic solvents. In that manner Fe ion is extracted from the sulfuric acid solution as a second chloride complex to the second organic solvent (B).

Abstract: A portable radio telephone comprises a receiver section (20) including at least an RF amplifier (22) and a first frequency mixer (23). The telephone also comprises a battery (15) which supplies a first voltage to the receiver section (20) when the telephone is in portable use. When the telephone is mounted on a vehicle, a vehicle battery (34) applies a second voltage which is higher than the first voltage, to the RF amplifier (22) and to the frequency mixer (23). By this higher voltage supply, the intermodulation characteristic and reception sensitivity of the receiver section can be improved in the vehicle-mounted use. On the other hand, battery saving can be achieved by the lower voltage supply in the portable use.
