Snow removing machine includes an auger for removing accumulated snow, an accumulated snow height detection section for detecting a height of accumulated snow in front of the auger, an auger lifting and lowering section for lifting and lowering the auger, and a control section for controlling the auger lifting and lowering section to lift the auger in response to detection, by the accumulated snow height detection section, of the accumulated snow. By the provision of the accumulated snow height detection section, the present invention can save a human operator a trouble of setting in advance a target height position of the auger and thereby alleviate a load on the human operator.

摘要:
An agricultural wheel tire has a tire tread having first and second lateral edges defining the width of the tire tread, and two sets of lugs. Each lug of the first set extends from a center of the tread width and terminates at the first lateral edge of the tire tread. Each lug of the second set extends from the center of the tread width and terminates at the second lateral edge of the tire tread. The first and second sets of lugs extend in an alternating manner in a circumferential direction of the tire tread so that corresponding side and end surfaces of adjacent first and second lugs and corresponding surfaces of the tire tread form substantially spherical-shaped depressed portions of the tire tread. The spherical-shaped depressed portions are arranged in the circumferential direction of the tire tread so that when the wheel tire is driven on soft soil, the spherical-shaped depressed portions engage and are buried in the soft soil and the soft soil is gathered inward of the spherical-shaped depressed portions and gradually hardened so that soft soil located between and surrounding the adjacent first and second lugs increases in hardness to thereby prevent the wheel tire from sinking into the soft soil so that the wheel tire has sufficient driving force.

A self-propelled walk-behind snowplow vehicle has a vehicle body and a vertical engine mounted on an upper part of the vehicle body. The vertical engine has a crankshaft disposed generally vertical and a cylinder head disposed generally horizontal to a longitudinal direction of the snowplow vehicle. The cylinder head projects from the vehicle body in a rearward direction of the snowplow vehicle. Left and right traveling units are mounted on a lower part of the vehicle body at left and right sides thereof. A muffler is connected to the engine and is disposed below the engine and located between the left and right traveling units. The vehicle body and the left and right traveling units together define a downward opening space within which the muffler is disposed.

A self-propelled walk-behind snowplow vehicle includes a vehicle body, an engine mounted on an upper part of the vehicle body, left and right traveling units mounted on a lower part of the vehicle body at left and right sides thereof, and a muffler connected to the engine. To lower the level of exhaust sound and to provide obstruction-free field of forward vision to the operator, the muffler is disposed below the engine and located between the left and right traveling units.

An image processing apparatus is disclosed by which correction of convergence and correction of distortion of an image can be performed with a high degree of accuracy. Correction data to be used for correction of position errors of the three colors of red, green and blue obtained by an adjustment apparatus in advance are stored in a storage section. The stored correction data are outputted to a correction waveform outputting section through a control circuit when necessary. The correction waveform outputting section produces correction waveforms based on the correction data inputted thereto and outputs the correction waveforms to a clock signal generation circuit. The clock signal generation circuit generates clocks, and the video data of red, green and blue stored in the memory are read out in response to the clock signals.
摘要:
Left and right driven wheels are connected to a pair of continuously variable transmissions and independently driven. The driven wheels are increased or decreased in speed at the same rotational numbers by operation of a change lever so as to move a vehicle forward or backward. When a steering angle of a steering wheel exceeds a predetermined value, an inner wheel speed during turning of the vehicle is decreased and an outer wheel speed during turning of the vehicle is increased so as to turn the vehicle. If the steering wheel becomes greater than the predetermined value during forward running of the vehicle at a low speed, the inner driving wheels stop and the vehicle does a stationary turn. However, during forward running at a high speed or backward running of the vehicle, even if the steering wheel becomes greater than the predetermined value, the vehicle does not do a stationary turn. With this arrangement, it is possible to always obtain the optimal steering characteristic in accordance with variations of the vehicle speed or the steering wheel.

The present invention relates to an ultrasonic diagnosis apparatus for radiating ultrasonic waves in a cross section of a subject by color Doppler scan, detecting the intensity of reflected echo, and brightness-modulating the intensity of the reflected echo, thereby obtaining a tomogram of the subject, and also for detecting a frequency-deviation (Doppler shift) of the reflected echo and detecting the direction and flow velocity of a blood flow in the subject, thereby displaying the blood flow two-dimensionally by coloring the blood flow portion in the tomogram in accordance with the detected flow velocity and direction. The apparatus of the present invention has a control means for controlling the scan-timings for B-mode scanning and CFM scanning independently, and thus, the frame rate for B-mode scanning and that for CFM scanning are controlled independently. The B-mode scanning frame rate can be controlled to be higher than CFM scanning frame rate. Therefore, the realtime following ability for displaying B-mode image is improved compared to the conventional color Doppler scan.
