    摘要: The present invention is directed in one aspect to methods of making free-standing, internally-supported, three-dimensional objects having an outer surface comprising a plurality of intersecting facets wherein a sub-set of the intersecting facets have a diamond layer of substantially uniform thickness. The diamond layer may be formed by chemical vapor deposition (CVD) over the surface of a substrate that has been fabricated to form a mold defining the sub-set of intersecting facets. A backing layer may be formed over at least a portion of the exposed diamond layer to enhance the rigidity of the layer when the substrate is removed.

    摘要: Apparatus is provided for controlling the operation of a switch mode power inverter having a known limited frequency range in dependence upon a variable-frequency timing waveform having a greater frequency range. Measuring means (21) are provided for measuring the frequency of the timing waveform and circuit means (18) uses this to generate a synchronising pulse train having a frequency which is an integral multiple or sub-multiple of the frequency of the timing waveform and is within the operating range of the power inverter.

    摘要: Switching power supply for generating a voltage for a pulsating load (2), in particular for generating a helix voltage for a TWT. The switching power supply is provided with a dc voltage source (1), a buffer (12) from which the load (2) is powered, and switches (3) and a control circuit (5) for regulating the charging of the buffer from the dc voltage source (1), whereby the power supply is provided with a circuit coupled to the dc voltage source (1), which circuit consists of a current source (6), the above-mentioned switches (3) and a primary (9) of a converter (7). The buffer (12) is powered from the secondary (11) of the said converter (7). The control circuit (5) controls the switches (3) by means of a signal which is a function of the rhythm of the pulsating load and the voltage across the buffer.
