Filed: 1982-04-19
Abstract: PURPOSE:To very effectively wash wafers with high efficiency by sequentially sending many wafers only to a pure wafer supply apparatus and then flowing pure water in the direction opposing to the wafer loading direction. CONSTITUTION:When a wafer is loaded to a jig 7 and is sent to a first vessel 4 from a hole 9, the wafer rotates along the inclined bottom surface of vessel 4. A gate plate 2 is closed and the wafer 13 is washed for the specified period. The plate 2 moves upward and the wafer is sent to a second vessel along a groove 8 which is formed like the jig 7 and washing time is controlled by open and close conditions of a gate plate 3. Wafers are washed with pure water supplied from the up-stream side. In the final vessel 6, a jig 12 is loaded by an actuator 11 at the upper side, it is moved toward a side 14' and is set to the waiting condition. The jig wafers to be sent is housed and sent to the upper side. Thereby, the jig 12 is sent to the next process. The pure water 10 is always supplied to the bottom of a vessel 6 and waste water overflows from the upper edge of the aperture 4 and vessel 6 and flows in the direction opposing to the wafer loading direction. With this structure, many wafers can be automatically washed with high efficiency.

Title: Front wheel rotation driving control device for moving vehicle
Inventor: NISHIKAWA FUMIAKI
IPC: F16D48/06
Filed: 1994-04-01
Abstract: PURPOSE:To improve travel driving transmission efficiency without devastating a plowed field surface by discriminating the rotation ratio of front and rear wheels by changing a control command of a 'front wheel speed increasing four-wheel drive condition D' to a 'rear wheel two-wheel drive condition C' after a prescribed short time, and switching and controlling both drive conditions according to this result. CONSTITUTION:Signals of respective sensor 9, 10 and 11 of front and rear shaft rotation and a steering angle are inputted to a CPU 13, and direct-coupled speed increasing clutches 7 and 8 are thrown in and disengaged. This CPU13 throws in the speed increasing clutch 8 when the steering angle of front wheels 4 becomes a prescribed angle 12 or more and puts it in a 'front wheel speed increasing four-wheel drive condition D', and changes this control command to a 'rear wheel two-wheel drive condition C' to disengage both clutches 7 and 8. The rotation ratio between front and rear wheels 4 and 3 is judged by a discriminating means, and both drive conditions are switched and controlled by a control part according to this result. Thereby, since travel can be carried out under delicate control in response to a condition change in a traveling plowed field surface, damage of the ground surface can be reduced to the minimum, and ground driving transmission performance can be exhibited when a moving vehicle travels at its maximum speed.
