    Abstract: In an oscillator circuit employing a pattern coil on a printed-wiring circuit board as a resonator circuit, in order to satisfactorily adjust dispersion in oscillation frequencies, an air-core coil wound by 0.5 turn and less than one turn is provided so as to be connected to the pattern coil in parallel and mounted on the printed-wiring circuit board. The oscillation frequency is adjusted by adjusting the angle of the air-core coil relative to the printed-wiring board.

    Abstract: A coil is wound either with insulated wire or space wound with uninsulated wire and subsequently coated with a solder resist or insulating material. If insulated wire is used, the insulation is removed from the wire either during or after winding at predetermined locations to match the location of connection pads in a conductive pattern on a substrate. The coil is appropriately aligned and laid down on the substrate and an attachment technique is used to form an electrical connection between the exposed areas of wire and connection pads on the substrate. Alternatively, uninsulated wire may be used, which is space wound and coated with a solder resist or insulating material. The uninsulated wire may either be masked prior to coating or the insulating material may be removed following coating to form exposed connection locations on the coil corresponding to the location of the connection pads on the substrate. An attachment technique is then used to form an electrical connection between the exposed areas of wire and the corresponding connection pads on the substrate.

    Abstract: An overload protector for a telephone set or other telecommunications terminal comprises an electrical component having DC continuity and DC resistance mounted by leads on a circuit board, the leads soldered to the conductor pattern. On application of an overload, the component heats up to a level at which sufficient heat travels along the leads to melt the solder. Usually both leads become unsoldered. One or both leads part from the conductor pattern under the effect of gravity; under the effect of a compression spring on one or both leads and held in compression between component and circuit board; or a combination of both. A convenient component is a carbon block resistor, in the Tip or Ring line. A heat insulating member can be positioned around the component. The insulating member can be a sleeve loosely fitting over the resistor and retaining heat in the resistor, or a coating or layer directly on the component.

    Abstract: One aspect provides an apparatus for locking circuit boards in position between a pair of guide rails. The apparatus can include a slider attached to a sidewall of one guide rail. The slider is allowed to slide along the guide rail within a predetermined range and one or more plunger-and-spring assemblies. A respective plunger-and-spring assembly comprises a plunger and a spring surrounding the plunger, and the plunger is inserted into a through-hole on the sidewall of the guide rail such that a first end of the plunger can be aligned with a notch on a corresponding circuit board and a second end of the plunger is in contact with the slider. Sliding of the slider causes the spring to compress and decompress and the first end of the plunger to move in and out of the notch on the circuit board, thereby facilitating locking and unlocking of the circuit board.
