20100067042 | Image forming apparatus and data transferring method - A plotter repeats a process of standing by until the next line synchronization timing after data transfer for one line and transferring DMAC control information requesting data transfer for one line to an MCH for each line synchronization timing whereby image data for one page is transferred. Therefore, data transfer from the MCH to the plotter is processed by continuous posted requests, so that float with respect to a line period can be made longer without transmitting a plurality of data transfer requests from the plotter to the MCH in the split method. Thus, a high data transfer performance can be realized with an inexpensive circuit because the cost for mounting a buffer memory or the like on the circuit is not needed. | 03-18-2010 |

20090178404 | Electrically driven brake booster and master cylinder - An electric booster according to the present invention comprises a booster piston disposed around an input piston so as to movable relative to the input piston. The booster piston and input piston also serve as a primacy piston of a tandem master cylinder. A brake fluid pressure is generated in the tandem master cylinder by an input thrust force provided from a brake pedal to the input piston and a booster thrust force provided from the electronic actuator to the booster piston. In this electric booster, a slide hole is formed through the secondary piston of the tamed master cylinder in the axial direction therefore, and a rod member is slidably disposed through the slide hole. When the fluid pressure is not increased in the primary pressure chamber, due to the fluid pressure in the secondary pressure chamber, the rod member comes to abut against the input piston, and a reactive force in the secondary pressure chamber is returned to the brake pedal. | 07-16-2009 |
