摘要:
A method of forming a branch-off seal between a heat-shrinkable sleeve and at least two spaced-apart elongate substrates, which comprises the steps of:(a) positioning the substrates within the heat-shrinkable sleeve;(b) positioning between the substrates and within the sleeve at an open end thereof a plug having a larger cross-sectional size at a first position away from said open end and a smaller cross-sectional size at a second position towards said open end;(c) positioning a heat-activatable sealing material at the first position;(d) shrinkable conduits in the sleeve by positioning one or more clips at the open end of the sleeve such that the substrates and the plug are in respective conduits; and(e) while the clip remains on the sleeve, applying heat so as to affect shrinkage of the sleeve to activate the sealant, and form the desired seal.
摘要:
A nozzle chip (3) for ejecting a liquid such as in an electrospray device is built from a substrate chip having grooves (5, 7) on a top surface. A lid (25) is attached to the top surface closing the grooves to form channels one of which has an open outlet end (9). At the outlet end a nozzle is formed at or attached and it has an outlet opening from which the liquid is to be ejected. Alignment recesses (13, 15) are made at edges of the substrate chip and they are accurately positioned in relation to the outlet opening, the alignment recesses allowing an accurate mounting of nozzle chip giving the outlet opening of the nozzle a reproducible position in the device where it is to be used. At the outlet end a recess (17) in the substrate chip can be provided and the nozzle can then be located in the recess to mechanically protect it.
摘要:
Engine speed data (N) and engine fueling data (MFDES) are processed to develop rate-of change data values for both engine fueling (FUELING_DIFFERENCE_FILTERED) and engine speed (ENGINE SPEED_DIFFERENCE_FILTERED). The latter are processed according to a look-up table (30) to select a data value for an adder (ENGINE SPEED/FUELING_ROC_ADDER). The adder data value is added to the data value of a control parameter, such as engine fueling (MFDES), to compensate for engine transients.
摘要:
A multi-beam electron gun provides a plurality N of cathode assemblies comprising a cathode, anode, and focus electrode, each cathode assembly having a local cathode axis and also a central cathode point defined by the intersection of the local cathode axis with the emitting surface of the cathode. Each cathode is arranged with its central point positioned in a plane orthogonal to a device central axis, with each cathode central point an equal distance from the device axis and with an included angle of 360/N between each cathode central point. The local axis of each cathode has a cathode divergence angle with respect to the central axis which is set such that the diverging magnetic field from a solenoidal coil is less than 5 degrees with respect to the projection of the local cathode axis onto a cathode reference plane formed by the device axis and the central cathode point, and the local axis of each cathode is also set such that the angle formed between the cathode reference plane and the local cathode axis results in minimum spiraling in the path of the electron beams in a homogenous magnetic field region of the solenoidal field generator.
摘要:
A coupled cavity traveling wave tube has periodic permanent magnet (PPM) RF cavity structures, each of which has a plurality of permanent magnets placed substantially equidistant from a central axis, and which are outside the extent of a plurality of electron beam tunnels arranged substantially equidistant from the central axis and within the extents of the plurality of permanent magnets. Each coupled cavity RF structure is formed by adjacent ferrous polepieces and a cylindrical wall which is beyond the extent of one or more coupling apertures which couple RF energy from one coupled cavity structure to an adjacent RF cavity.

A periodic permanent magnet (PPM) klystron has beam transport structures and RF cavity structures, each of which has permanent magnets placed substantially equidistant from a beam tunnel formed about the central axis, and which are also outside the extent of a cooling chamber. The RF cavity sections also have permanent magnets which are placed substantially equidistant from the beam tunnel, but which include an RF cavity coupling to the beam tunnel for enhancement of RF carried by an electron beam in the beam tunnel.
