A semiconductor device can be fabricated by forming a floating gate layer over a semiconductor body. The back surface has a top portion curving backward with respect to the front surface of the case to provide an overhanging portion forming a clip to mount said case and is mountable in a recess between the driver side inner window surface and the driver side inner door so that the holder hangs on the driver side below the window and near the driver so as to be within range of a driver. Two or more subdomains of impingement jets are provided through the outer wall, and one or more metering outlets is provided through the inner wall, all communicating with a respective channel. The display control section is configured to control the display section to display at least one of the predetermined data units of the image data for which the processing for generating the image data is ended based on the progress information. The digital telephone is operable to generate digital telephony packets representative of voice data.
