20100191528 | SPEECH SIGNAL PROCESSING APPARATUS - A speech signal processing apparatus comprising: a control signal output unit configured to receive as an input signal either one of a first speech signal corresponding to a sound uttered by a user and a second speech signal corresponding to a sound output from an eardrum of the user when the user utters a sound, and output a control signal corresponding to a noise level of the input signal; and a speech signal output unit configured to output either one of the first speech signal and the second speech signal according to the control signal. | 07-29-2010 |
20150082774 | WORK VEHICLE - A work vehicle includes a vehicle body, a guiding pipe, a first heating section, and a second heating section. The vehicle body has a partition wall that partitions a space in an inner section into a first region and a second region. The guiding pipe is configured to guide a reducing agent. The guiding pipe has a first pipe section and a second pipe section. The first pipe section is positioned inside the first region. The second pipe section is positioned in the second region. The first heating section heats the first pipe section. The second heating section heats the second pipe section and adjusts the temperature independently from the first heating section. | 03-26-2015 |
20150086314 | WORK VEHICLE - A working vehicle includes a vehicle, an engine, an exhaust treatment apparatus, a connecting pipe, a reducing agent injection apparatus, a reducing agent pump and a guiding pipe guiding reducing agent from the pump to the injection apparatus. The engine, exhaust treatment apparatus, connecting pipe, and reducing agent injection apparatus are arranged inside an engine room of the vehicle body. The engine has a crank shaft, and intake and exhaust manifolds arranged on first and second direction sides of the crank shaft, respectively. A first accommodating space is positioned on a first direction side of the engine room. A reducing agent pump is arranged inside the first accommodating space. A guiding pipe is arranged so as to pass inside the engine room on the first direction side with regard to the crank shaft. | 03-26-2015 |
20150090511 | REDUCING AGENT TANK AND WORK VEHICLE - A reducing agent tank includes a tank body storing reducing agent and a cylindrical gauge member visually indicating a storage amount of the reducing agent inside the tank body. The gauge member is in communication with an inside of the tank body. The tank body has a replenishment port to replenish the reducing agent. The gauge member is provided on a first wall surface of a plurality of wall surfaces defining the tank body. The gauge member is provided in a slanted manner relative to a bottom plate of the tank body. The replenishing port and the gauge member are disposed in a row along a direction that extends along the first wall surface as seen in a plan view. | 04-02-2015 |
20150090517 | WORK VEHICLE - A work vehicle includes a reducing agent tank, a battery, a reducing agent tank mounting member, a battery cover and a first guide member. The battery and the tank are positioned in a row. The mounting member has a bottom plate, and a partition plate extending upward from the bottom plate between the tank and the battery. The tank is mounted on the bottom plate. The battery cover has an upper plate above the battery, and a side plate extending downward from a side of the upper plate between the tank and the battery. The first guide member extends from the side plate toward the tank and slopes downward. Preferably, a first end of a second guide member disposed below the first guide member is positioned closer to the battery than a distal end of the first guide member, with the second guide member sloping downward toward the tank. | 04-02-2015 |
20150174746 | FILTER REMOVER - A filter remover removes a cylindrical filter element housed in a housing through an opening provided in the housing. The filter remover includes: an attachment portion provided with a screw to be screwed onto the opening; an insert portion that includes a base end integrated with the attachment portion and a tip end in a form of a free end, that is elastically deformable in a radial direction orthogonal to an axial direction of the filter element in conjunction with a movement in the axial direction caused when the attachment portion is screwed, and that is inserted through the opening into a center hole provided in the filter element as the attachment portion is screwed; and an engaging portion that is provided at the tip end and that is engaged with the filter element after the attachment portion is moved for a predetermined amount when the attachment portion is screwed. | 06-25-2015 |
20150211209 | ENGINE UNIT - An engine unit mounted to a vehicle frame, the engine unit includes: an engine; an engine support mechanism to be coupled to the vehicle frame, with at least one vibration absorbing mechanism disposed on each of both sides of the engine in an orthogonal direction to a crankshaft of the engine, to support the engine; an aftertreatment device to purify exhaust gas emitted from the engine; a base bracket provided to the engine support mechanism; and an upper bracket detachably fixed and mounted to the base bracket, the upper bracket supporting the aftertreatment device. | 07-30-2015 |
20150240447 | HYDRAULIC EXCAVATOR - A hydraulic excavator includes an engine, a rotating frame, a vehicle body frame, a diesel particulate filtering device, a selective catalytic reduction device and a connecting pipe. The rotating frame supports the engine. The vehicle body frame is provided in a standing manner on the rotating frame, and includes a plurality of column members. The a diesel particulate filtering device and the selective catalytic reduction device process exhaust from the engine, and are supported by the vehicle body frame. The connecting pipe has an extendable bellows part in at least a portion. The connecting pipe connects the engine and the diesel particulate filtering device. The bellows part is located further away from the engine as the bellows part inclines further downward. | 08-27-2015 |
20150240454 | WORK VEHICLE - A work vehicle having a plurality of working modes allowing working in accordance with a load state includes an engine, an exhaust gas purification apparatus, a reducing agent tank, a state determination portion, and an engine control unit. The exhaust gas purification apparatus purifies a nitrogen oxide in an exhaust gas. The reducing agent tank stores a reducing agent. The state determination portion determines a state of the reducing agent. The engine control unit controls output of the engine with the use of a restricted-operation engine output torque curve in which horsepower output from the engine is lower than horsepower output from the engine at the time when each of the plurality of working modes is selected, when a state of the reducing agent is equal to or lower than a reference value. | 08-27-2015 |
