Title: Backward elevation controller of rotary tiller unit
Inventor: MUKAI NAKASHIRO
IPC: A01B63/10
Filed: 1990-01-31
Abstract: PURPOSE:To keep the up-travel amount from the ground almost constant without fail and enable a stable work by equipping the subject controller capable of elevating the subject rotary tiller unit so that the up-travel position thereof may be determined by addition of a constant height based on the height from the ground. CONSTITUTION:When a change lever is shifted to a backing zone in a change guide, a backing-detection switch 41 becomes ON followed by sending of a signal to a controller 27. A rotary tiller unit is then elevated to a constant height from the height of a lift arm during a tilling work. As the up-travel position is always determined based on the height of the lift arm during the work before elevation, the up-travel amount from the ground surface can be always kept almost constant without no problems even in case of change of the tire size, etc., thus improving its workability.

Title: Wire electric discharge machine
Inventor: OBARA HARUKI
IPC: B23H1/02
Filed: 1988-02-04
Abstract: PURPOSE:To prevent damage to a workpiece caused by a short circuit detecting voltage by providing a short circuit means for automatically or manually short- circuiting between a wire and a workpiece at the time of finishing machining or a short-circuit voltage cutting means for cutting off the application of voltage between the wire and the workpiece from a short-circuit detecting means. CONSTITUTION:Normally, during machining, since the minus level of the voltage of a machining power source 4 is higher than the minus level of a short circuit detecting voltage -V, no current flows in a diode 9 and the short circuit detecting voltage -V is inputted into the input terminal of a comparator 8 and, since the minus level of the voltage is higher than that of a reference voltage -VL, no output is given from the comparator 8. In a machining stopped condition, a numerical control device 10 automatically or manually turns on a relay RL1 to short-circuit between an electrifying piece 3, i.e., a wire 1 and a workpiece 2. As a result, the short circuit detecting voltage -V will not be applied between the wire 1 and the workpiece 2, without causing electrolytic corrosion to the workpiece 2.

Abstract: PURPOSE: To maintain electrical insulation between the respective divided box bodies of the captioned unit with each other by disposing a watershed member above the mutual edges of the divided box bodies across the edges and providing a discharge valve mechanism which is opened in the fixed position in the rotating direction.  
     CONSTITUTION: Electric insulation cell units 5a, 5b, 5c are slewed by way of a drive shaft 2 through driving of a motor 44. A pump 49 is run to first supply water onto the watershed member 23 of the 1st unit 5a. Here, a valve body 14 is held closed by a spring 18 and therefore the unit 5a and stationary water receiving cell 4a are held electrically insulated. As the unit 5a turns, the cam face 21a rises to pull up the valve body 14, causing the water to flow down into the cell 4a. The water receiving chamber 24 is electrically communicated with an electrolytic unit 28. The water supplied into the unit 28 through a discharge barrel 26 is electrolyzed and the alkaline water and acidic water are supplied onto the member 23 on the units 5b, 5c respectively. Since each divided box body 7 has an air spacing with each other, even if dew deposits on the box body 7 surfaces, the insulation state may be maintained electrically and discretely.
