This invention pertains to a method for producing hydrogenated silicon oxycarbide films having low dielectric constant. With this arrangement, it is possible to provide an LED driving circuit that easily realizes low current consumption and high-speed emission for the LED. The sleeve is generally characterized by first and second sleeve segments, each having first and second sleeve ends. When a desired item name is clicked, the picture plane is switched and the contents corresponding to the clicked item name are displayed. A calculation unit includes a means for optimizing the image quality over a particular area defined by the compression element. The method further includes transmitting the status-acceptance packet to a control unit.
