Abstract: For forming a contact electrode to an n-type contact layer of a gallium nitride-based compound semiconductor, the n-type contact layer of the gallium nitride-based compound semiconductor is exposed to an oxygen plasma to form an oxygen-doped surface layer in a surface of the n-type contact layer, and then, an electrode metal is formed on the oxygen-doped surface layer. With this arrangement, an n-type contact electrode having a low specific contact resistance is obtained with good reproducibility, with performing no annealing after formation of the electrode metal.

Abstract: When deterioration of a NOx purifying device due to sulfur contamination is detected, a specific operating state flag FHL is set to “1,” and, at intervals equal to or shorter than, for example, three seconds, the air-fuel ratio of an air-fuel mixture to be supplied to an engine is varied so that it is alternately leaner and richer than the stoichiometric air-fuel ratio. When the temperature TCAT of the NOx purifying device exceeds a deterioration recovery temperature STCAT2 while the air-fuel ratio variation control is being executed, the SOx removing flag FHLSOx is set to “1,” and for a period equivalent to the deterioration recovery time TRSOx, the air-fuel ratio is maintained richer than the stoichiometric air-fuel ratio.

Abstract: In a PBX network, a global database is provided in each PBX node for storing shared data for verification of authorized mobile stations when accessing the network via a wireless cell-site station. During a wireless mode, a mobile station monitors the strength of its downlink signal from a first cell-site station of a first PBX node. If it falls below a threshold, the mobile station begins a scan across the spectrum. If a strong signal is detected, it stops the scan and transmits a handover request message to a second cell-site station transmitting that strong signal. The second node receives the message via the second cell-site station to establish the mobile's verification. If the mobile station is an authorized user, the second node transmits a handover grant message to the second cell-site station, transmits a command message to the first node for a switchover to a link between the first and second nodes, and connects the link to the second cell-site station.

Abstract: A plunge-cutting forming tip which improves chip disposal. A protrusion (11) is disposed on a rake face (7) in the vicinity of the ridgeline of a plunge-cutting edge (3). In cutting by means of the tip (1), a chip (K) is ejected which is not only merely thin, but also is ejected in such a manner as to be partially squeezed as a result of pressing against the protrusion (11). Accordingly, the chip is ejected such that a cross section thereof is deformed into a channel shape instead of assuming a flat shape. Thus, the rigidity of the chip is increased, so that chip disposal is improved accordingly.
