The invention is concerned with novel heteroarylacetamides of formula Rd\u2014C\u2014N\u2014Rc\u2014CH2\u2014C\u2014N \u2003\u2003 wherein Ra to Re are as defined in the description and in the claims, as well as physiologically acceptable salts thereof. A power supply, which applies a cleaning bias of the opposite polarity to an electric charge polarity of the toner that forms a toner image, is provided, and volume resistivity of the dielectric layer is set to 1E3 ohm-cm or more. The reflective component is disposed near a wafer carrying device to reflect an image of the wafer carrying device to the image capture module. % with respect to all metallic atoms; is chiefly constructed from a \u03b2-GaInO3 phase and an In2O3 phase; provides an In2O3 phase \u03b2-GaInO3 phase X-ray diffraction peak intensity ratio that is 45% or less; and has a density of 5. The aerosol generator can be incorporated in a hand held inhaler. Also provided are analogues related to epothilone A and B and intermediates useful for preparing same.
