Title: Ink jet recorder
Inventor: OSHIMA NORIYOSHI
IPC: B41J2/175
Filed: 1991-10-04
Abstract: PURPOSE:To obtain an appropriate recording density regardless of the carrying control of recording paper set by controlling the conduction start timing of a heater with timings corresponding to a plurality of carrying controls. CONSTITUTION:In case of manual feed, conduction is carried out with conventional timing (Conduction of a heater 21d is started upon start of reverse rotation of a paper feed motor) according to a conduction time indicated on a table. Ambient temperature is the detected, pulse conduction time is determined, and pulse conduction start is set at the start of reverse rotation of motor. In case of automatic paper feed, conduction start must be delayed as compared with manual paper feed on condition that the timing at the start of reverse rotation of paper feed motor is employed and thereby conduction start is delayed behind the start of reverse rotation of paper feed motor thus setting the heater to a recording position at the starting time of conduction with same timing as manual paper feed even in case of automatic paper feed.

IPC: F02B37/12
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To improve driveability without increasing exhaust emission by controlling exhaust gas recirculation means and a centrifugal supercharger of variable nozzle type using the intake air amount as a parameter while in the range for performing exhaust gas recirculation. SOLUTION: When a running condition of an internal combustion engine 1 is in the range for performing the exhaust gas recirculation(EGR), an electronic control unit(ECU) 100 controls an EGR valve 19 constituting the exhaust gas recirculation means and a centrifugal supercharger of variable nozzle type 7 using the intake air amount as a parameter. That is, the target intake air amount per rotation of a crank shaft is calculated using an engine speed and accelerator opening degree as parameters, and the actual intake air amount and the target intake air amount are compared for controlling.  With this control mechanism, when the actual intake air amount is smaller than the target one, for example, a boost pressure from the centrifugal supercharger of variable nozzle type 7 is raised while decreasing the opening degree of the EGR valve 19, thus reducing EGR gas supplied to a combustion chamber of each cylinder 1a to 1d, and increasing the intake air amount.
