摘要： An I.D. collet has a housing with a hollow bore and an undercut portion; a taper screw slidable into and out of the hollow bore of the housing and having a conical head; a spindle having a hollow bore in alignment with the hollow bore of the housing for receiving the conical head of the taper screw into and out of the hollow bore of the spindle such that the conical head enlarges the diameter of the spindle; and a draw nut assembly threadably connected to the taper screw and having tangs abutting the undercut portion of the housing when the spindle reaches a preset location in the hollow bore of the spindle to prevent further enlargement of the spindle when the tangs come into contact with the undercut portion of the housing.

摘要： A low inductance mount for decoupling capacitors. In one embodiment, a circuit carrier such as a printed circuit board (PCB) includes a surface layer, a first layer adjacent to the surface layer, and a second layer adjacent to the first layer. A conductive region is implemented on the surface layer, and is electrically coupled to a first circuit plane in the first layer. At least one mounting pad is located on the surface layer of the PCB within the conductive region. The mounting pad is electrically isolated from the remainder of the conductive region and is electrically coupled to a second circuit plane in the second layer. A capacitor is mounted on the PCB, wherein a first terminal of the capacitor is coupled to the conductive region and a second terminal is coupled to the mounting pad.

摘要： A remote voltage regulator module (VRM) for high-current, low voltage applications. In one embodiment, an electronic system includes a VRM configured to provide a DC output voltage. The VRM is coupled to a load board via a first bus bar and a second bus bar. The VRM includes a first capacitance of a first amount, while the load board includes a second capacitance of a second amount. A loop between the VRM and the load board is formed by the first and second bus bars and first and second capacitances. The loop is characterized by a transfer function that is second order or less.

摘要： Three vertical deflection windings of corresponding three deflection yokes that are mounted on three cathode ray tubes of a projection video are coupled in series through corresponding three connector pairs. Three horizontal deflection windings of the corresponding three deflection yokes are coupled in parallel through the corresponding three connector pairs. When any of the three connector pairs is left disengaged, a disabling signal that is indicative of a loss of a vertical deflection current in the series coupled vertical deflection windings is generated. The disabling signal is coupled to a corresponding video driver of each of the cathode ray tubes for providing beam current blanking to protect the screens of the tubes against a screen burn damage.
