An image converting apparatus includes a memory which can store frame information of an image to be played, and an image processing section which can read frame information from the memory and convert the frame rate to a predetermined frame rate in response to a predetermined state and in accordance with the play state. According to an example embodiment of the present invention, a portion of substrate is removed from the back side of a semiconductor chip having a SOI structure and a backside opposite a circuit side. Finally, a phase control signal for carrying out a phase control is generated by using the obtained amount of correlations. The liquid product stream, which has a substantially lower sulfur and nitrogen content than the original feedstream is passed to a second hydrodesulfurizing stage also containing one or more reaction zones where it is reacted in the presence of hydrogen and a second hydrodesulfurizing catalyst at hydrodesulfurizing conditions.
