摘要： A cermet resistive film is deposited on an alumina substrate to form a fixed resistance between a pair of spaced termination points. A portion of the resistive film is removed to form a pair of resistor sections separated by an insulating gap. A fusible link which includes a layer of cadmium material is deposited in the gap to provide electrical continuity between resistor sections and the resistor body is then covered with a protective coating. When a maximum temperature is reached due to an overload current, the fusible material melts and opens circuit.

摘要： An electrical circuit device having a ceramic substrate including a thick or thin film circuit on at least one surface thereof and an elongated groove formed in a surface substantially normal to the first mentioned surface. In one embodiment the elongated groove is divided into juxtaposed alternately distended and constricted portions, the constricted portions being adapted to receive an end portion of relatively flat lead wires. Prior to insertion of the lead wires, the respective constricted groove portions and the surface portion extending laterally therefrom are first metallized to define conducting areas leading to the respective lead wires. The lead wires are inserted and soldered in place.

摘要： Feedthrough filters for bypassing high frequency interference signals away from a conductor carrying low frequency or direct current energy are shown. These filters employ a metal oxide type of varistor material as a dielectric between capacitor electrodes with a high dielectric constant Epsilon , and the non-linearity of current flow through the varistor material with respect to applied voltage varies by such an exponential factor that the filter functions in usual manner as a high frequency bypass for low energy interference, but as an ohmic current bypass for high energy interference regardless of frequency.

摘要： A simple method and apparatus is disclosed for the calibration of a numerically controlled milling machine or the like, to determine the compliance for a particular set-up of the machine. The apparatus includes a hydraulic cylinder mounted on the machine bed, with the end of the hydraulic piston bearing against a non-rotating cutting tool that is mounted in the spindle. A pressure gauge or pressure switch indicates fluid pressure in the hydraulic cylinder to determine force of the piston on the cutting tool, and a deflection sensor measures the static deflection of the spindle. In one apparatus, hydraulic fluid from a high pressure source passes through a pressure-reducing valve into the rear of the hydraulic cylinder to push the piston rod end against the cutting tool, without requiring motion of the spindle relative to the bed, the valve being adjusted to maintain a desired fluid pressure behind the piston despite leakage of fluid past the piston.

摘要： A compensated high voltage suppressor for insertion in a transmission line is shown for shunting large interference voltages from the line to ground. The suppressor has a varistor material through which the large interference voltages are shunted, and this material also functions as a capacitor dielectric. Additional circuit components are connected with this capacitance to form a low pass filter in the transmission line which has a characteristic impedance substantially matching the line characteristic impedance. This impedance matching maintains effective transmission for power, or signals conducted along the line in the normal mode of operation.

摘要： A rotor of a switch actuator includes a selector cam having a serrated cam surface which mates with the serrated cam surface on a selector cam follower. The selector cam follower is slidably retained within an actuator sleeve which surrounds the rotor and the cam follower is forced into mating engagement with the selector cam by a bias spring. The force of the spring is translated by the serrated cam surfaces into a torque which provides a snap-action when the rotor is rotated between its selectable positions.

摘要： An analog error signal is received from a machine tool position sensor. Its magnitude is sensed by a comparator circuit including an operational amplifier and a digital output level is generated when a particular analog voltage level is sensed. The digital output level resets the position sensor to restore the analog output signal and the comparator circuit to their initial state. A reset circuit, including two monostable circuits, generate a delayed reset pulse to the input of the comparator to reset its output if the analog input signal fails to do so. Forward and reverse directional circuits including NAND logic gates are connected together in parallel to the comparator output and conditioned by forward and reverse reference signals to convey the digital output from the comparator when the machine is moving in the direction to which the comparator has been preconditioned.
