摘要： The present invention relates to a method and apparatus for pulverizing a material to produce a fine powdery material such as silica powder as a material for a filler for sealing semiconductors. It has a shell and a screw shaft mounted in the shell. A disk having an inverted conical bottom surface is coaxially secured to the bottom of the screw shaft. The disk serves to protect the blade of the screw shaft from wear. Also owing to the inverted conical bottom surface, a centripetal force acts on the screw shaft while in rotation, thus preventing it from running out of true. By providing a plurality of screw shafts in the shell, the fluid in the shell flows in a complicated manner, thus increasing the pulverizing efficiency. A partitioning plate formed with a hole in the upper or lower part thereof may be provided between the adjacent screw shafts to minimize the possibility of shortcircuiting of the material from the inlet of the shell to its outlet. The respective screw shafts may have different revolving speeds, different heights or different screw pitches from one another to create a complicated fluid flow in the shell and thus to improve the pulverizing efficiency.

摘要： A power transmission for driving a vehicle wherein a high-low speed changer is disposed between an engine and a primary speed change mechanism. The speed changer comprises a planetary gear mechanism provided between an input shaft and an output shaft, a speed increasing clutch for causing the gear mechanism to effect a speed increase, and a direct coupling clutch for coupling the input shaft to the output shaft via the gear mechanism without speed change. Since the torque transmitted to the speed change mechanism is small, the transmission can be compact in its entirety.

摘要： A steering control system for a self-propelled working vehicle having steerable front and rear wheels. The control system comprises sensors for detecting a directional or orientation error and a sideways error of the vehicle relative to a reference line or lines extending in a vehicle running direction, and a control unit for steering the vehicle in response to signals received from the sensors. The control unit is capable of steering the vehicle in a turn steering mode for turning the front and rear wheels to the same steering angle in opposite directions and a parallel steering mode for turning the front and rear wheels to the same steering angle in the same direction. When the directional error and the sideways error take place simultaneously, the control unit determines directions and angles for turning the front and rear wheels to correct the two errors simultaneously.

摘要： A propelling drive control apparatus for a working vehicle comprising hydraulically operable friction clutches, a first clutch control valve for selecting between the friction clutches, and a second clutch control valve connected in series to the first clutch control valve. The second clutch control valve is manually switchable to a declutching position for disengaging the friction clutches, a first clutch engaging position for engaging one of the friction clutches, and a second clutch engaging position intermediate between the declutching position the first clutch engaging position. In this second clutch engaging position one of the friction clutches is operable under a lower hydraulic pressure than in the first clutch engaging position.

摘要： A cabin construction of a wheel loader having a vehicle body with a driver's section at a rear position, a backhoe detachably attached to a rear end of the vehicle body and a cabin for covering the driver's section. The improvement includes a detachable rear end cabin door construction which permits an easy and economical exchange of the rear door as necessary for the varying uses of the vehicle. A first door is used when the vehicle body is attached with the backhoe whereas a second door is used when the vehicle body is used without the backhoe. The feature has eliminated the necessity of costly and troublesome replacement of the entire cabin construction and is advantageous also for forming a compact the rear end of the vehicle.
