The present invention is directed to a system and method for creating and editing documents or messages by dynamically loading the required data on the computing device as the documents or messages are being created or edited. It is possible to use the container efficiently and transfer different substrates in size with one container. The cap and housing together form a first space to contain an electrical device with a smaller size when cap is positioned in a top position. The only type of diffusion connected to the first output of the low-pass filter is a P-type diffusion. Thus, the wavelength of laser light of a fluorine laser, which has been band-narrowed from 1-2 pm to about 0. According to the present invention, a sintered body of aluminum titanate having high mechanical strength and ability to be stably used at high temperatures, as well as its inherent properties of low coefficient of thermal expansion and high corrosion resistance, can be obtained.
