A plasma generator comprises a radio frequency power source, a coaxial cavity resonator assembly, and a direct current power source. The radio frequency power source provides a voltage supply of radio frequency power having a first ratio of power over voltage. The resonator assembly includes a center conductor coupled to the radio frequency power source, and also includes a virtual short circuit. The direct current power source is connected to the center conductor at the virtual short circuit, and provides a voltage supply of direct current power having a second ratio of power over voltage that is less than the first ratio.

A cleaning device for a surface, such as a windshield of a vehicle, includes an active positioning system and a cleaning head. The active positioning system is configured to deploy from a storage position hidden from view within a covered storage space and to position the cleaning head upon the windshield. The active positioning system includes a first extension member and a second extension member that move relative to one another to position the cleaning head, and also move the cleaning head across the windshield along a path. The cleaning head can have a brush portion configured to agitate debris from the window, and a drying portion configured to dry the window after cleaning. The cleaning device can be controlled via a touch-screen display in the vehicle, enabling a user to direct that specific portions of the windshield be cleaned as desired.

An exhaust device incorporated in a vehicle for travel on uneven terrains. The exhaust device includes an air blowing device and an exhaust pipe through which exhaust gas generated in a prime mover is directed out of the vehicle. The exhaust pipe includes an upstream pipe, a downstream pipe, and a joint device joining the upstream pipe to the downstream pipe in a manner permitting the upstream pipe to move relative to the downstream pipe, the air blowing device being disposed to blow cooling air toward the joint device.

A structure of an active mount is provided. The structure includes a case with an interior that is divided into upper and lower fluid chambers, a sealed hydro fluid flows based on a volume change of the upper fluid chamber due to deformation of an insulator, and flow characteristics of the hydro fluid are varied when power is applied to a driver. The structure further includes a generator that produces electricity based on behavior of the insulator. The generator is disposed within the case and the electricity produced by the generator is applied to the driver. Additionally, the generator autonomously produces electricity based on engine behavior and is mounted within an engine mount and, thus, supply of electricity from the outside is not required.

Vehicle traction device, mainly for land vehicles, of the type comprising a motor and a transmission wherein the motor preferably has an axial rotation, such as an electric motor, wherein the motor rotation is coplanar and concurrent with the primary shaft of the transmission, and wherein the primary shaft is in turn coaxial to the output shaft, such that the output shaft crosses the primary shaft and extends beyond the ends thereof.

A work vehicle includes a power transmission unit having a differential device for transmitting power to left and right axles and a power transmission mechanism for transmitting power to the differential device, and a transmission shaft for transmitting power to the power transmission unit. The power transmission mechanism includes a first gear mechanism to which power from the transmission shaft is transmitted and a second gear mechanism for transmitting power from the first gear mechanism to the differential device.

A bulldozer according to the present application includes a main frame, and an engine, a hood and an exhaust after-treatment device are provided on the main frame, an air inlet of the exhaust after-treatment device is in communication with an air outlet of a turbine of the engine via a pipeline, and the exhaust after-treatment device is fixed to the hood. In the bulldozer, vibration generated by the engine is transmitted to the main frame through an engine supporting frame or a damping device, and then transmitted from the main frame to the hood, the transmission path of the vibration is long, thus the vibration damping becomes complicated and has a high damping value, and the vibration transmitted to the air cleaner is really small.
