IPC: B41J2/185
Filed: 2002-09-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide an ink jet recording device which can discharge ink without being obstructed by pressure absorption of bubbles in the ink and can prevent jetting failures by making a jetting pressure of the ink at the time of a flushing operation higher than at the time of printing.  <P>SOLUTION: When a maintenance process is started, a purging operation (S1 and S2) and a wiping operation (S3 and S4) are carried out. Then, the flushing operation is carried out (S5 and S6). After the purging operation, the ink remaining in a suction cap is drawn into an ink jet head from a jetting nozzle by a back pressure from an ink cartridge. The ink includes many of bubbles generated by an intense flow of the ink at the time of the purging operation. The ink including bubbles can be discharged without being obstructed by the pressure absorption of the bubbles by carrying out the flushing operation with the higher ink jetting pressure than at the time of printing.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-10-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide a drive system, in which the change of the tension of a belt due to inertia torque variations associated with the variation in engine revolution is reduced, without using a clutch pulley, and the mountability of a generator is improved.  <P>SOLUTION: The two electric generators are connectively bridged by the single belt, and an excitation current of a rotor of one of the two electric generators is on/off-controlled as follows. That is, when it is turned on, a high voltage is applied to a field coil, thus accelerating the startup of generation, and when it is turned off, the current of the filed coil is made to circulate in a closed circuit between a diode resistor, thus accelerating the further attenuation of the generation compared with the case having no resistor. According to this configuration, generated torque is controlled with proper timing so as to reduce the inertia torque variation of the rotor due to the variations in the revolution, and the change of the tension of the belt is reduced.  <P>COPYRIGHT: (C)2004,JPO
