Publication number: 20050219564Abstract: Sequences of items may be maintained using ordered locks. These items may correspond to anything, but using ordered locks to maintain sequences of packets, especially for maintaining requisite packet orderings when distributing packets to be processed to different packet processing engines, may be particularly useful. For example, in response to a particular packet processing engine completing processing of a particular packet, a gather instruction is attached to the particular identifier of a particular ordered lock associated with the particular packet. If no longer needed for further processing, the packet processing engine is immediately released to be able to process another packet or perform another function. The gather instruction is performed in response to the particular ordered lock being acquired by the particular identifier, with the gather instruction causing the processed particular packet to be sent.Type: ApplicationFiled: July 14, 2004Publication date: October 6, 2005Applicant: FUJI XEROX CO., LTD.Inventor: Yasuhiro Arai

Publication number: 20050190125Abstract: Pulse generating sections (1X, 1Y) convert a DC voltage (Vs) into voltage pulses (Vp), and apply the pulses to the sustain and scan electrodes (X, Y) of a PDP (20). Recovery switching devices (Q3X, Q4X, Q3Y, Q4Y) of power recovery sections (2X, 2Y) are turned on and off under the rising and falling edges of the voltage pulses (Vp), thereby connect recovery inductors (LpX, LpY) to recovery capacitors (CX, CY). Then, the recovery inductors (LpX, LpY) resonate with the panel capacitance (Cp). While the amounts of the resonance currents (ILX, ILY) are small, the inductances of the recovery inductors (LpX, LpY) are high. When the amounts of the resonance currents (ILX, ILY) exceed a threshold value, the inductances of the recovery inductors (LpX, LpY) are reduced.Type: ApplicationFiled: February 14, 2005Publication date: September 1, 2005Inventors: Satoshi Ikeda, Yasuhiro Arai, Manabu Inoue
