Title: Current switching circuit
Inventor: KIMURA YASUO
IPC: H03K17/56
Filed: 1989-04-25
Abstract: PURPOSE:To prevent the lowering of current precision owing to a temperature change and the difference of a current amplifier rate beta, etc., by connecting the emitters of a pair of transistors in common and connecting them to a constant current source and connecting MOS transistors in parallel between bases and collectors. CONSTITUTION:When high and low input potentials are added to first and second input terminals 1 and 2, the first MOS transistor(TR) 21 and the first bipolar transistor TR 10 go to off-states. Then, the second MOS TR 22 and the second bipolar TR 11 go to on-state. When a current flowing in the constant current source 6 is set to be IEE1, a current equal to IEE1 flows in an output terminal 5. When a potential added to the first and second input terminals 1 and 2 are inversed and they go to the low and high input potentials, the action opposite to the action is executed. Consequently, the lowering of current precision especially owing to the unbalance of beta of the bipolar transistor TR can be controlled.

Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a locus control device in which moving locus can be controlled at high speed and high precision even in case where an interval between teaching points is short. SOLUTION: A line of teaching points is parted to blocks (S22). At this time, it is parted when a folded angle of a locus is sharper than a specified angle, and when a subsequent action is not moved by only an attitude change of a tool. An acceleration completion point which is apart for a necessary distance to accelerate to the highest speed from a block starting point, and a deceleration starting point which is apart from a block ending point for a necessary distance to decelerate from the highest speed to the speed of zero are determined, and inner parting points are set between the block starting point and the block ending point (S24). A movable body is then moved through the respective inner parting points (S26-S36). That is, the inner parting points are newly set along the plural teaching points for controlling a tool, thereby the tool can be fed at the highest speed even when an interval between the teaching points is short.
