摘要： A word processing apparatus includes a random access memory for temporarily storing the document data, and a floppy disc for permanently memorizing the document data. A character number counter is included in the word processing apparatus, which develops a control signal when, for example, 100 stroke key input operation is conducted through a keyboard panel. In response to the control signal, the document data temporarily stored in the random access memory is transferred to the floppy disc for updating the document data memorized in the floppy disc.

摘要： The data processing terminal unit in the form of a point of sale transaction device disclosed herein contains a keyboard for introducing data into the data processing terminal unit and a cassette tape deck which includes a cassette type magnetic tape and a cassette tape recording scheme for data storage. There are provided an E key and an M key on the keyboard for introducing end marking signals (EM signals) which indicates completion of data entry. The EM signals are introduced into the data processing terminal unit when the E key and the M key are depressed successively or simultaneously, thereby preventing erroneous introduction of the EM signals at an undesired time.

摘要： A cermet has a hard phase which contains W and nitrogen, and includes at least one selected from a carbide, nitride and carbonitride of a metal having Ti as a main component, and a binder phase having an iron group metal as a main component. A W amount contained in the whole cermet is 5 to 40% by weight, an interfacial phase including a complex carbonitride with a larger W amount than a W amount of the hard phase being present between grains of the hard phase, and when a W amount contained in the interfacial phase based on the whole metal element is represented by Wb (atomic %), and a W amount contained in the hard phase based on the whole metal element is represented by Wh (atomic %), then, an atomic ratio of Wb to Wh (Wb/Wh) is 1.7 or more. The cermet is excellent in fracture resistance and wear resistance.
