20100018187 | INTERNAL COMBUSTION ENGINE CONTROL DEVICE - An internal combustion engine control device includes a NOx adsorber catalyst disposed in an exhaust passage, an EGR passage, a reducing agent adding device, a torque fluctuation reducing device, and a fuel injection device. The EGR passage draws a portion of exhaust gas from the exhaust passage downstream of the NOx adsorber catalyst and recirculates the exhaust gas into the intake passage. The reducing agent adding device adds a reducing agent to exhaust gas upstream of the NOx adsorber catalyst to reduce substances adsorbed by the NOx adsorber catalyst. When or after the reducing agent adding device adds the reducing agent, the torque fluctuation reducing device advances the timing of the fuel injection device or carries out a pilot injection to reduce a fluctuation in engine torque. The reducing agent adding device adds less reducing agent while the torque fluctuation reducing device is operating. | 01-28-2010 |

20100126142 | INTERNAL COMBUSTION ENGINE EXHAUST GAS CONTROL SYSTEM AND CONTROL METHOD OF INTERNAL COMBUSTION ENGINE EXHAUST GAS CONTROL SYSTEM - In a control method of an internal combustion engine exhaust gas control system which is applied to a hybrid vehicle that is powered by an internal combustion engine and an electric motor, an exhaust throttle valve, provided downstream of an exhaust gas control catalyst, is controlled to reduce its opening amount to a target opening amount when it is determined that warm-up control of the internal combustion engine needs to be executed. Next, a target injection quantity of fuel necessary to increase the temperature of exhaust gas flowing into the internal combustion engine to a target exhaust gas temperature is calculated. Then, assist torque from the electric motor is adjusted so that the sum of torque from the internal combustion engine when the fuel injection quantity has been set to the target injection quantity and the assist torque substantially equals a required torque. | 05-27-2010 |

20100316400 | IMAGE FORMING APPARATUS - In an electrophotographic image forming apparatus employing a contact development system, contact of a development roller | 12-16-2010 |
20100316413 | IMAGE FORMING APPARATUS - A toner pattern is detected by a color misregistration detection sensor to detect a duration of contact between a development roller and a photosensitive drum. A contact/separation motor for driving the development roller is accelerated or decelerated based on the detected duration of contact between the development roller and the photosensitive drum. This control enables shortening the duration of contact between the development roller and the photosensitive drum, thus reducing the shortening of their lifetime. | 12-16-2010 |
20110052275 | IMAGE FORMING APPARATUS - The image forming apparatus detects color deviation amount in a timing when a developing roller separates from or contacts a photosensitive drum to set a difference in peripheral velocities between the photosensitive drum and an intermediate transfer belt or a transfer material conveying belt based on the color deviation amount and information about the use degree of intermediate transfer belt. | 03-03-2011 |
20140369704 | IMAGE FORMING APPARATUS WITH DEVELOPING UNIT SEPARABLE FROM PHOTOSENSITIVE MEMBER - An image forming apparatus includes: a scanning unit configured to scan a photosensitive member with light; a developing unit configured to develop a latent image; a driving unit configured to cause the developing unit to come into contact with the photosensitive member or to be separated from the photosensitive member; and a control unit configured to let the scanning unit perform a preparation operation, in order for the scanning unit to form the latent image. The developing unit is separated from the photosensitive member while the preparation operation of the scanning unit is performed, and the control unit is configured to start, before the preparation operation of the scanning unit is completed, controlling the driving unit to bring the separated developing unit into contact with the photosensitive member. | 12-18-2014 |
