摘要： This position-controlling apparatus is able to increase servo rigidity when an operation is suspended. When controlling the suspension of an operation at a fixed position, a positional error signal (ER) obtained by the D/A conversion of the output of a present position counter (107) is applied to an operational amplifier (111) as a velocity command, and the deviation of the velocity command from a detected velocity (VS) is applied to a motor (100) through a velocity amplifier (115) and a power amplifier (103). The variable gain of the velocity amplifier (115) is increased by achangeover signal (GCS) when a low-velocity detection circuit (114) judges that the detected velocity is lower than a predetermined velocity.

摘要： A positional loop gain control method in which a positional control feedback system composed of a speed control circuit (101c), a spindle motor (102), a position coder (104), a fixed-position stop control unit (101e), and a changeover switch (101b), determines the gain of a digital-to-analog converter (301) constituting the fixed-position stop control unit so that the positional loop gain of the positional control feedback system has a set value Kp. When controlling the position at which a spindle stops, the method comprises a step of operating the spindle motor at a predetermined speed Nb, a step of measuring a deceleration time Tf required for the speed of the spindle motor to drop from Nb to zero, and a step of determining a gain KDA of the digital-to-analog converter using the set value Kp, the predetermined speed Nb, the decelaration time Tf, and a distance D between a fixed position and a changeover point at which a speed-control mode is shifted to a position-control mode.

摘要： Legs are protruded from four corners of an oblong metal plate, and screw holes are formed near the center of the metal plate such that screws can be inserted therethrough to be screwed into terminals of a threaded terminal-type electronic component, thereby forming terminals for connection to electronic components. The legs of the terminals are inserted into small holes formed in a printed board, soldered to an electric circuit, and thus secured to the printed board. Screws are inserted into the screw holes of the terminals so as to be screwed into the terminals of the threaded terminal-type electronic components. The screws are then tightened to fasten the electronic components to the printed board.
