20100058743EXHAUST GAS CLEANING SYSTEM FOR DIESEL ENGINE - Each time a starting process for a diesel engine 03-11-2010
20100122522EXHAUST GAS PURIFICATION SYSTEM FOR ENGINEERING MACHINE - An exhaust gas purification system for an engineering machine is capable of avoiding decreases in working efficiency during regeneration control by burning off a deposit of particulate matter from a filter efficiently during a work pause time. An operating section 05-20-2010
20100138118TRAVELING SYSTEM FOR ENGINEERING MACHINE - This invention provides a traveling system for an engineering machine, adapted to limit a maximum traveling speed of the machine without causing decreases in engineering work efficiency or in accelerating performance during a start of traveling, and to improve fuel efficiency by suppressing a loss of engine output horsepower under the limited state of the maximum traveling speed.06-03-2010
20100170227EXHAUST GAS CLEANING SYSTEM FOR ENGINEERING VEHICLE - An exhaust gas cleaning system for an engineering vehicle, such as a hydraulic excavator, is capable of performing manual regeneration control of a regeneration fuel injector 07-08-2010
20100326058WORKING MACHINE - Disclosed is a working machine capable of preventing damage to a filter due to excessive accumulation of particulate matter (PM), even under a situation that requires, prior to compulsory regeneration of the filter, moving the machine to a place in which to perform the regeneration work.12-30-2010
20110000197WORKING MACHINE - An exhaust gas treatment filter removes particulate matter from exhaust gas of a diesel engine. The particulate matter which accumulates on the filter is removed by a manual regeneration system that can simply be controlled. After a manual regeneration switch 01-06-2011

20090055062GEAR SHIFTING CONTROL SYSTEM FOR WORK MACHINE - A work machine gear shifting control system provides gear shifting conditions for an automatic gear shifting mode in accordance with work site conditions. An area 02-26-2009
20090267612ANTENNA CABLE BREAK DETECTOR FOR CONSTRUCTION MACHINE WIRELESS COMMUNICATION APPARATUS AND CONSTRUCTION MACHINE WIRELESS COMMUNICATION APPARATUS - An antenna cable break detector used with a construction machine wireless communication apparatus to detect a break in an antenna cable. The antenna cable 10-29-2009
20100004834GEAR SHIFTING CONTROL DEVICE FOR WORK MACHINE - A work machine gear shifting control device is capable of readily identifying the cause of failure in learning the clutch hydraulic pressure for operating a transmission clutch. A transmission gear shifting control section 01-07-2010
20100277590Construction Machine - [Problem] To provide a construction machine, which can surely perform confirmation of conditions around a machine body upon starting work and can start a prime mover even when obstruction exists around the machine body.11-04-2010
20110113766Vehicular Back Processing System - An exhaust gas post-treatment system for a vehicle is provided, which in the course of regeneration ascertains whether or not there is any object approaching a body of the vehicle from behind. A filter is arranged in an exhaust passage of an engine to trap PM therein. A trapped and deposited PM amount sensing device senses a deposited amount of PM deposited in the filter. A fuel injector burns and removes PM deposited in the filter to conduct regeneration of the filter. A rearward monitoring camera monitors a scene rearward of a vehicle body. A display module displays monitoring information from the rearward monitoring camera, and a controller having a regeneration processing unit executes control processing to actuate the fuel injector and to perform regeneration. The controller includes a display continuation processing unit for executing control processing such that during the regeneration by the fuel injector, the monitoring information from the rearward monitoring camera is continuously displayed on a display screen of the display module.05-19-2011
20110128116Communication System - In a work machine, a communication system is provided, in which, when damage of disconnection or the like of a communication line occurs, desired communication is enabled without requiring manual replacement of the damaged communication line. The communication system is provided in a hydraulic excavator and comprises a vehicle body controller 06-02-2011

20090093340Shift Control Device for Work Vehicle - A shift control device for a work vehicle that has a stepped automatic transmission includes: a control device that controls an engine rotation rate at the work vehicle and the stepped automatic transmission; a forward/reverse switchover member that outputs a forward/reverse switchover command for the work vehicle; and an operation quantity detection device that detects an accelerator pedal operation quantity in the work vehicle is operated. As the forward/reverse switchover command is output via the forward/reverse switchover member, the control device executes forward/reverse switchover control for the stepped automatic transmission and also controls the engine rotation rate so as to decrease the engine rotation rate gradually to a target lower limit value selected to ensure that a reverse rotation of a turbine runner at a torque converter in the work vehicle does not occur.04-09-2009
20090312922Clutch control device and clutch control method - A clutch control device includes: a plurality of hydraulic clutches built into a transmission; a clutch switching pattern storage device in which a plurality of clutch switching patterns, each defining engage/release changeover timing with which the plurality of hydraulic clutches are engaged/released are stored in correspondence to individual speed change patterns adopted by the transmission; a clutch switching pattern selection device that selects a clutch switching pattern stored in the clutch switching pattern storage device in correspondence to a speed change pattern for the transmission at a time of speed change; and a hydraulic control device that executes hydraulic control for the plurality of hydraulic clutches in correspondence to the clutch switching pattern selected by the clutch switching pattern selection device.12-17-2009
