Title: Ink jet head having an improved ink discharging outlet face and ink jet apparatus provided with said ink jet head
Inventor: KIMURA MAKIKO
IPC: B41J2/165
Filed: 1993-10-18
Granted: 2000-05-16
Abstract: This invention is directed to prevent an ink jet inactivation state which is induced when ink droplets adhering to the jet port surface of an ink jet head reach the jet port, and is characterized by including a water repellent region in the proximity of the jet port disposed on the jet port surface and a groove-like hydrophilic region inside a region spaced apart by a predetermined distance from the jet port and adjacent to the water repelling region.

Abstract: A Carrier Sense Multiple Access with Automatic Abort collision avoidance (CSMA/AA) controller for application in a wireless local area network (LAN).  The CSMA/AA controller reduces the number of invalid states arising from collision conditions on the communication channel.   The controller features hardware logic control for time critical functions. The  hardware  logic  circuit  detects  events  and  fault conditions under the CSMA reservation protocol which may otherwise be missed by the Medium Access Control software layer and aborts the transmit procedure.  The off-loading of time critical functions also improves the performance of the system and reduces the variability arising from overhead execution times associated with the system CPU.
