摘要： A wire-wound type chip coil can take various inductance values while maintaining its outer dimension at a specified fixed value. A chip coil is formed by winding at least two conductive wires regularly in a single layer around a core made of a magnetic material and firmly connecting both ends of each conductive wire to terminal electrodes disposed on respective flanges of the core. This makes it possible to obtain a great current capacity. Furthermore, the inductance decreases because of an increase in the magnetic path length. A great number of different inductance values can be easily obtained by properly selecting parameters including the number of substantially parallel conductive wires, the diameter of each conductive wire, and the number of turns.

摘要： Image data and the image-reproduction instruction data corresponding to the image data are stored in a recording medium. A specified-image reading section selectively reads the image data intended to be reproduced by the user, among the image data recorded in the recording medium. A signal processing section and a layout processing section generate a sheet used for checking the contents of the image data for which reproduction is specified, before the corresponding image is reproduced. An output unit outputs the sheet.
