Title: Voltage supply circuit for amplifier
Inventor: NOJIRI KAZUHIKO
IPC: G05F1/56
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To limit the rise of a supply voltage even when a supply current to an amplifier fluctuates by selectively supplying either high voltage or low voltage to the amplifier corresponding to the level of the output signals of the amplifier and limiting the level of the high voltage to be less than a prescribed size at the time of selectively supplying the high voltage to the amplifier.

When the output voltage eo of the amplifier becomes high and a fieldeffect transistor(FET) 1 is turned on, the high voltage VH from the power supply circuit PS is outputted from an output terminal 8 to the amplifier. At the time, even when the emitter voltage of a transistor 3 rises corresponding to the output voltage eo of the amplifier, the gate voltage of the FET 1 is limited, the FET 1 is turned to an active state, the rise of the voltage supplied from the gate of the FET 1 to the output terminal 8 is suppressed to the voltage lower than a maximum voltage capable of taking the high voltage VH and it is supplied to the amplifier as the power supply voltage +B.

Title: Method and apparatus for controlling speed and programmable controller
Inventor: YUGUCHI TASUKU
IPC: H02P8/14
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the application of an impact to a driven element by deciding the necessity or not of controlling the speed of the element during accelerating by calculation, and controlling at a constant speed less than the controlled speed if the necessity of the control of the speed is judged by the decision, and then decelerating the element. SOLUTION: A CPU 12 reads an acceleration, deceleration, control speed, starting speed and target pulse number of parameters from a RAM 14, and compares with predetermined conditions. As a result of the comparison, whether the speed during accelerating is controlled or not is decided. When the conditions for controlling the speed is satisfied, a pulse output IC 16 outputs a pulse in response to the acceleration to start a pulse motor, thereby starting the movement of a driven element. The element is controlled at a constant speed with the pulse frequency constant for a predetermined time from the time point of arriving at the control speed, gradually decelerated to output no pulse. Thus, no impact is applied to the element.

IPC: B23H7/10
Filed: 1985-06-24
Abstract: PURPOSE:To feed the wire reliably to the starting hole of machining by pulling the tip of wire into the pipe thus protecting the wire from bending. CONSTITUTION:Upon cutting of wire 1 through a cutter 13 and moving a guide roller 5 in the arrow direction, the tip of wire 1 projecting from the tip of pipe 22 is pulled into the pipe 22. Under this state, the wire 1 is fed out synchronously with the motion of slider 14. Consequently, the pipe 22 will pass between a movable cutter 23 then penetrate through an upper guide 26 and further penetrate through a starting hole 24 of machining of work 25 to stop at the lower guide 27. Then a feed roller 7 will function to feed out the wire 1 thus to feed the tip of wire 1 into the lower guide 27. Upon holding of wire 1 on the lower guide 27, the slider 14 is returned to waiting position. Since the tip of wire 1 is retracted into the pipe 22, the wire 1 can be fed into the starting hole 24 of work 25 reliably.
