| 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 |
| 20110066822 | DATA TRANSFER APPARATUS, DATA TRANSFER DEVICE, AND DATA TRANSFER METHOD IN A DATA TRANSFER DEVICE - A data transfer apparatus includes: a first port and a second port that communicate data; a memory unit that stores the data; and a securing unit that secures, when a first time period starting from transmission of data up to reception of a response to transmitted data at the first port is longer than a second time period starting from transmission of data up to reception of a response to transmitted data at the second port, a first memory space that is used in data transfer in the first port so as for the first memory space to have a larger size than a size of a second memory space used in data transfer in the second port. | 03-17-2011 |
| 20110225341 | COMMUNICATION APPARATUS, COMMUNICATION SYSTEM AND ADAPTER - A communication apparatus for carrying out communications to and from an external apparatus that includes a first interconnecting unit and a first non-transparent port and effects an interconnection for communications via the first non-transparent port is provided. The communication apparatus includes a second interconnecting unit that includes a second non-transparent port communicably connected to the first non-transparent port. The second interconnecting unit effects an interconnection for communications via the second non-transparent port. The second interconnecting unit performs, when the communication apparatus carries out communications to and from the external apparatus, address translation between an address for use by the communication apparatus and an address for use by the second non-transparent port. | 09-15-2011 |

| 20080229740 | Electrically actuated brake booster - An electrically actuated brake booster capable of obtaining a desired boost ratio for a given input pressure when an electric actuator is activated as a boost source, so as to ensure a desired operability of a brake pedal. The electrically actuated brake booster comprises: an input piston | 09-25-2008 |
| 20090033144 | BRAKE APPARATUS - A brake apparatus includes a master cylinder hydraulically connected to a wheel cylinder, and a booster hydraulically connected between the master cylinder and the wheel cylinder. The master cylinder includes: a first pressure chamber arranged to output brake fluid in accordance with manipulation of an input device, and hydraulically connected to a wheel cylinder; and a second pressure chamber arranged to output brake fluid in accordance with the manipulation of the input device. The booster includes: a booster cylinder; a booster piston movably mounted in the booster cylinder, the booster piston dividing an internal space of the booster cylinder at least into a boost pressure chamber and a back pressure chamber, the boost pressure chamber being hydraulically connected to the wheel cylinder, the back pressure chamber being hydraulically connected to the second pressure chamber; and an electric actuator arranged to actuate the booster piston. | 02-05-2009 |
| 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 |
| 20100213072 | METHOD OF MANUFACTURING CHROMIUM PLATED ARTICLE AND CHROMIUM PLATING APPARATUS - A pulse current from a pulse current supply side is fed to a middle part of an anode holding body to which anodes are connected; both end portions of a cathode holding body, to which cathodes are connected, are connected to a negative pole on the pulse power source side; and inductances of wiring between adjacent anodes and inductances of wiring between adjacent cathodes are set at a ratio of 1:2:3:4 in a direction of spacing from a connection to the pulse power source side. Pulse currents are equally fed to each work and it can be ensured that chromium plating treatment of each work is made equal. | 08-26-2010 |
