摘要： A class D audio amplifier provides both an audio output signal and a DC bias voltage to an electrostatic transducer (9). In the amplifier, a modulated sequence of pulses is generated by an input module (1) in response to an input audio signal. The sequence of pulses is amplified by an output module (3) using high speed switching output transistors (4, 5). An output signal is generated by applying a low pass filter (8) to the amplified pulses, and the output signal is provided to the transducer to produce audible output. The amplified sequence of pulses is also used to drive a voltage multiplier module (10) to provide bias voltage for the electrostatic transducer (9). In other embodiments, the bias voltage is provided by a bias voltage module which reverses the bias voltage at intervals, and a phase reverser (13) reverses the phase of the signals fed to the output module (3) simultaneously with reversal of the bias voltage.

摘要： Thermally imageable lithographic printing plate precursors and heat-sensitive compositions for use in these printing plate precursors are disclosed. The compositions contain an aqueous developer soluble polymer, such as a phenolic resin; a compound that reduces the aqueous developer solubility of the polymer; and optionally, and infrared absorber. Examples of compounds that reduce the aqueous developer solubility of the polymer are those that contain at least one quarternized nitrogen atom, such as quinolinium compounds, benzothiazolium compounds, pyridinium compounds, and imidazoline compounds. On thermal imaging, the irradiated areas become more soluble in the aqueous developer and can be removed to form a positive image.

摘要： This invention is directed to a precursor for preparing a resist pattern by heat mode imaging, the precursor comprising a heat sensitive composition, the solubility of which in an aqueous alkaline developer is arranged to increase in heated areas, and a means for increasing the resistance of non-heated areas of the heat sensitive composition to dissolution in an aqueous alkaline developer (the “developer resistance means”), wherein said developer resistance means comprises one or more compounds selected from the group consisting of: (A) compounds which include a poly(alkylene oxide) unit; (B) siloxanes; and (C) esters, ethers and amides of polyhydric alcohols, wherein said heat-sensitive composition comprises an aqueous alkaline developer soluble polymeric substance (i.e. the “active polymer”) and a compound which reduces the aqueous alkaline developer solubility of the polymeric substance (i.e. the “reversible insolubilizer compound”) such that the aqueous alkaline developer solubility of the composition is increased on heating and the aqueous alkaline developer solubility of the composition is not increased by incident UV radiation. The invention provides a solution to the problem of the relatively narrow solubility differential between imaged and non-imaged areas of heat sensitive positive working radiation sensitive compositions.
