A method and apparatus for effective pyrolysis of a biomass utilizing rapid heat transfer from a solid heat carrier or catalyst. Dense particles such as magnesium hydroxide are ejected from a suitable ejector on to a baffle by which they are deflected across the width of the chamber and lengthwise over the length of a intermediate collecting zone to form the core layer while the initial and final collecting zone are substantially free of the dense particulate additive. When the bearing cup is angularly moved relative to a cross shaft, grease in the first oil passageways is flowed from the outer periphery side of the annular projected portion to the inner periphery side thereof, while grease in the second oil passageways is flowed from the inner periphery side of the annular projected portion toward the inner periphery side. A coded transcription of the poetry pattern forms is produced from input processing. The semiconductor device has an improved coupling coefficient, and reduced leakage current.
