Abstract: A first nitriding process step is performed in which a steel member is subjected to a nitriding process in a nitriding gas atmosphere having a nitriding potential with which a nitride compound layer having a ?? phase or an e phase is generated, and thereafter a second nitriding process step is performed in which the steel member is subjected to a nitriding process in a nitriding gas atmosphere having a nitriding potential lower than the nitriding potential in the first nitriding process step, to thereby precipitate the ?? phase in the nitride compound layer. It is possible to generate the nitride compound layer having a desired phase mode uniformly all over a component to be treated and to manufacture a nitrided steel member high in pitting resistance and bending fatigue strength.

Abstract: A cartridge 5 is mounted on a carriage 8. The carriage 8 includes liquid introducing parts 710m, 710c and 710y and a guide projection 723. The guide projection 723 is extended from between the liquid introducing parts 710m and 710c toward the liquid introducing part 710y. The cartridge 5 includes an ink supply port 507m connectable with the liquid introducing part 710m to supply magenta ink to the liquid introducing part 710m, an ink supply port 507c connectable with the liquid introducing part 710c to supply cyan ink to the liquid introducing part 710c, an ink supply port 507y connectable with the liquid introducing part 710y to supply yellow ink to the liquid introducing part 710y, and a first groove 580. The first groove 580 is extended from between the ink supply port 507m and the ink supply port 507c toward the ink supply port 507y to allow for insertion of the guide projection 723. This configuration suppresses diffusion of ink leaked from any of the liquid supply ports of the cartridge.

Abstract: Transistors using nitride semiconductor layers as channels were experimentally manufactured. The nitride semiconductor layers were all formed through a sputtering method. A deposition temperature was set at less than 600° C., and a polycrystalline or amorphous InxGayAlzN layer was obtained. When composition expressed with a general expression InxGayAlzN (where x+y+z=1.0) falls within a range of 0.3?x?1.0 and 0?z<0.4, a transistor 1a exhibiting an ON/OFF ratio of 102 or higher can be obtained. That is, even a polycrystalline or amorphous film exhibits electric characteristics equal to those of a single crystal. Therefore, it is possible to provide a semiconductor device in which constraints to manufacturing conditions are drastically eliminated, and which includes an InGaAlN-based nitride semiconductor layer which is inexpensive and has excellent electric characteristics as a channel.
