摘要:
To provide a dump truck capable of assuring a large authorized payload weight while inhibiting spilling of an object under haulage over parts of side walls. A dump truck is provided on a frame 3 with a tillable body 5. The body 5 has a payload section defined by a bottom wall, a front wall 8 and a pair of side walls 9 for loading therein an object to be hauled, and a canopy 10 connected to the front wall 8 of the payload section and arranged over an operator's cab 4. A front end portion 15 of a top part 14 of each of the paired side walls 9 included in the payload section of the body 5 is set at a same height position or a substantially same height position as the canopy 10, the front end portion 15 of the top part 14 of each of the side walls 9 has been connected by welding to a rear end portion 17 of an upper surface 16 of the canopy 10, a rear end portion 18 of the top part 14 of each of the side walls 9 is set at a height position lower than the front end portion 15, and the top part 14 of each of the paired side walls 9 is formed in a configuration including a rearwardly-declining oblique profile.

Disclosed is a body structure for a dump truck (1) having a body frame (3). The body structure is provided with hinge pins (5) to be located toward a rear of the body frame, a body (2A) to be tiltably disposed on the body frame via the hinge pins and to be adapted to load payload (9), and stiffening members arranged on outer surfaces of the body. The body is constructed at least of a floor board (62a), a front board (62b), side boards (62c), and a canopy (62d). The stiffening members include side-board stiffeners (61) connecting upper portions of elongated joints between the side boards and the front board to portions of elongated joints between the side boards and the floor board. The latter portions are located rearward of positions laterally corresponding to a barycentric position (G) of the payload (9) in a longitudinal direction of the body.

A body for a dump truck includes a body frame, a bottom wall, front wall, and left and right side walls arranged on the body frame. The body also includes an earth/sand anti-sticking device and a steel member arranged outside and opposite the earth/sand anti-sticking device such that a space is formed between the steel member and the earth/sand anti-sticking device. The body is provided with at least one steel rib arranged in the space, fixedly secured to the steel member to reinforce the steel member, and arranged extending upright toward the earth/sand anti-sticking device. The steel member is any one of the bottom wall, front wall, and left and right walls, and the steel rib is shaped to divide the space.

[Problem] To realize a body 5 having a light weight and sufficient rigidity, and therefore, to ease restriction on the authorized payload for a payload section such the authorized payload can be increased and the efficiency of hauling work by a dump truck can be improved. [Solution] A body is provided with earth/sand anti-sticking devices arranged in corner parts of a payload section defined by a bottom wall 7, a front wall 8, and left and right side walls 9, for example, sloping plates 14-16; and steel ribs 17a-17c arranged in hollow parts 25a-25c between steel members arranged outside and opposite the sloping plates 14-16, for example, the associated ones of the bottom wall 7, front wall 8 and left and right side walls 9, fixedly secured to the associated walls by welding to reinforce them, and arranged extending upright toward the sloping plates 14-16, respectively.

A video signal processor recursively removes noise from luminance signal data, storing only one frame of the luminance signal data, and detects luminance motion by comparing the current and stored luminance data to decide whether to output the current color difference data, the average of the current color difference data and the color difference data one frame before, or the average of the current color difference data and the color difference data two frames before. The decision may also involve detection of color noise by comparison of the color difference data with the data one frame before, or detection of color motion by comparison of the color difference data with data two or four frames before. Color data stored for color noise detection may also be used for recursive color noise removal. Accurate noise reduction is possible with a comparatively small amount of memory.

A front rotary working machine is provided which has rotary working portions disposed at a front portion of a transmission case, and a front wheel disposed forward of the rotary working portions. The working machine includes a guard member extending forward from the transmission case for guarding an upper side of the rotary working portions. A support device for supporting the front wheel is connected to the front portion of the transmission case. The support device has an upper portion connected to the guard member. A load applied from the front wheel to the support device is distributed to the transmission case and the guard member, resulting in strengthening of the support device.

A noise reduction circuit and method effectively reduce noise with a simple structure regardless of the partial content of an image while suppressing an increase in the capacity of the image memory used and process delays. The present invention forms noise-reduced data by utilizing a correlation between from the difference between a pixel subjected to noise reduction and data of a pixel that is shifted by a predetermined amount in a time direction and/or spatial direction, and forms a difference cause discriminating signal indicating whether the difference is due to a valid change of the image. The noise-reduced data and the difference cause discriminating signal are formed for a plurality of different correlations. Final noise-reduced video data are obtained by selecting a method for determining the final noise-reduced video data based on the difference cause discriminating signals, and accordingly selecting/combining the plurality of noise-reduced data.
摘要:
A CVD apparatus is able to efficiently perform purging treatment after maintenance by using for the purge gas a mixed gas of a high thermal conductivity and an inert gas. Purging treatment before semiconductor film formation is performed by repeating the pumping of a vacuum and the introduction of inert gas a plurality of times. In addition, in order to judge suitable maintenance times, the moisture concentration in reaction chamber is measured with a moisture meter connected to the reaction chamber when performing a corrosive gas treatment, and maintenance times are determined according to changes in the moisture concentration when corrosive gas treatment is performed repeatedly. In addition, in order to measure the moisture of corrosive gas while preventing obstruction of piping in a moisture monitoring apparatus, a moisture monitoring apparatus, including a pipe, of which one end is connected to reaction chamber into which corrosive gas flows, and a moisture meter connected to the other end which measures the moisture contained in the corrosive gas introduced from the reaction chamber, is equipped with a pipe beating mechanism.
