Title: Induction heating roller device
Inventor: KITANO YOSHIO
IPC: F16C19/52
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent a supporting rod for supporting an induction heating mechanism from rotating, when a rolling bearing for the rod becomes rotation disabled. SOLUTION: A rolling bearing 10 and a sliding bearing 14 are installed between the drive shaft 2 of roller 1 and a support rod 9. When the rolling bearing 10 goes into abnormal rotation, torque is transmitted from the drive shaft 2 to the support rod 9 via the rolling bearing 10. Until the torque is transmitted to the support rod 9, however, a slippage is generated between the bearing 10 and rod 9 owing to the action of the sliding bearing 14. With this slippage, the rod 9 will not make turn with co-rotation.

IPC: F02D43/00
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent a complete misfire and deterioration of the emission generated by performing roughness control, when the combusting condition is deteriorated caused by smoldering, etc., of an ignition plug at the time of being left idling. SOLUTION: A retardation prohibiting timer is set to a prescribed time (S116), when a combustive variation is sensed where the OBD misfire sensing value dac(i) exceeds three times the roughness deciding upper threshold (S116). If dac(i) exceeds three times that of the threshold during the timer being in operation, a retardation prohibiting continue flag for prohibiting the retardation of the ignition timing due to roughness control is raised, so that roughness control is inhibited (S122). If dac(i) is lowered, the retardation prohibiting timer is once set to the specified time (S118). The retardation prohibiting continue flag is returned to zero, and the inhibiting of roughness control is released (S119).

The side walls 12a and 12b are deformed in a direction in which they come closer, and ink is jetted out of the nozzle orifice 28 of an ink chamber 30b. Conversely, there is no potential difference between the side wall electrodes 16b and 16c, and therefore no ink is jetted out of the ink chamber 30c. Consequently, a character as a dot array is expressed on recording paper by controlling the potential of the side wall electrode on each side wall.
