An object of the invention is to provide a flat ceramic sheet including an internal electrode used for manufacturing a multilayer ceramic electronic part. Disclosed, for purposes of example, are kits for producing a stool, a chair, a desk and a table. The operating environment has a graphical user interface. With this arrangement, the electrical connector can be simply and easily mounted on the panel without increasing manufacturing cost. Data is asynchronously transferred using a FIFO between the device and the bus dependent upon the determined type of transfer.
