The invention is related to methods and apparatus for controlling and adapting a digital predistortion linearizer for amplification of bandlimited signals using non-linear amplifiers. The control method advantageously permits the predistortion function applied by a predistortion entity to provide a relatively constant gain. This attribute is advantageous for operation within cellular radio systems, which often employ digital power control systems. However, the disclosed techniques can also be applicable to virtually any type of digital predistortion for which an input signal or reference signal to be amplified is predistorted in a manner that is complementary to the distortion induced by a non-linear amplifier. Embodiments of the invention advantageously enhance the practicality of using digital linearization and predistortion amplification techniques. Embodiments of the invention can automatically adjust the characteristics of a predistorted signal so that a deviation from overall linearity is compensated and subsequently reduced while maintaining a nearly constant gain attribute.

For example, in one such process a gate structure of a transistor may be formed and, in a material surrounding the gate structure, a recess created so as to be aligned to an edge of the gate structure. Subsequently, a source/drain conducting material may be deposited in the recess. Such a source/drain conducting material may be deposited, in some cases, as layers, with one or more such layers being planarized following its deposition. In this way, the conducting material is kept within the boundaries of the recess.

The invention relates to electronic devices whose electronic properties can surprisingly be improved to a significant degree by inserting at least one crosslinkable polymeric buffer layer, preferably a cationically crosslinkable polymeric buffer layer, between the conductive doped polymer and the organic semiconductor layer. Particularly good properties are obtained with a buffer layer in which crosslinking is thermally induced, i.e. by raising the temperature to 50 to 250° C. Alternatively, crosslinking can be radiation-induced by adding a photoacid. Moreover, such a buffer layer can be advantageously applied by means of printing techniques, especially inkjet printing, as the ideal temperature for the thermal treatment is independent of the glass transition temperature of the material. This avoids having to rely on material that has a low molecular weight, making it possible to apply the layer by means of printing techniques. The next layer (the organic semiconductor layer) can also be applied with the aid of different printing techniques, particularly inkjet printing, because the buffer layer is rendered insoluble by the crosslinking process, thus preventing the buffer layer from solubilizing thereafter.

The piezoelectric/electrostrictive porcelain composition contains as a major component a piezoelectric/electrostrictive porcelain composition component including a PbMg1/3Nb2/3O3—PbZrO3—PbTiO3 ternary solid solution system composition and NiO or including a Pb(Mg, Ni)1/3Nb2/3O3—PbZrO3—PbTiO3 ternary solid solution system composition, and further contains lead germanate.

A fermented tea produced by primary-drying tea material leaves by means of a primary tea rolling dryer (primary drying step) to adjust the moisture content of raw leaves (tea material leaves) of bancha with low qualities (the second crop of tea, the third crop of tea, the shuto-bancha, the skiffed leaves of tea, and the like) to a constant moisture; subsequently, providing them in a tea roller (tea rolling step); adding loquat leaves during the tea rolling step in order to knead loquat leaves together with the tea material leaves; and fermenting and drying the kneaded tea material leaves and loquat leaves. The fermented tea is formed into a composition having, as an active component, the fermented tea obtained by tea-rolling processing of tea material leaves and loquat leaves, and an extract contained in the fermented tea.

The invention relates to a device for heating food comprising a frame, a pan or basket having an opening into which the food to be heated can be placed, which pan or basket can be coupled to the frame by means of coupling means and in which the frame comprises a heating element and a fan for circulating heated air in the pan or basket, and a drive for rotating the pan or basket about a non-vertical rotation axis during the heating of food in a heating position of the frame. The frame is designed such that the pan or basket can be coupled to the frame while the pan or basket is on a supporting surface with its opening directed upwards. The invention also comprises a method for heating food.
