摘要： An energy absorbing mechanical end stop for a high speed gear train that is used to drive a variable vacuum capacitor utilizes a friction plate that is mounted to a gear member of the high speed gear train as an energy absorbing mechanism. A wedge member is activated when the tuning of the variable vacuum capacitor approaches a limit and falls between the friction plate and the gear member to which the friction plate is attached. The friction between the friction plate and the wedge member brings the gear member to a stop without damaging the high speed gear train or the variable vacuum capacitor that is driven by the high speed gear train.

摘要： In a keyboard there are a plurality of key operated variable capacitor switches acting as differentiators to change the widths of electrical pulses which are then integrated to give signals whose level indicate which switches have been operated. The gain and operating points of amplifiers can be changed to change the transfer function of the electronics and thus increase the mechanical hysteresis of the switches.

摘要： A capacitive switch includes: an electrical circuit formed by two spaced pads of conductive material on an insulative substrate; and a capacitive coupling member on the end of a keystem wherein the end of the keystem has a looped ribbon formed by two layers of insulating material sandwiching a layer of conductive material. As the keystem is urged toward the substrate a monotonically increasing area of the ribbon mechanically contacts the pads so that a monotonically increasing capacitive coupling is made between the two spaced pads.

摘要： A variable capacitance switch element is disclosed in which varying capacitance is effected by increasing the active surface area of a capacitive coupling member in proximity to a second capacitive plate. The structure of the variable capacitive element is such that the capacitance of the device varies in nearly linear fashion with the depression of an actuator member.

摘要： A capacitor provides a plurality of selectable capacitance values, by selective connection of six capacitor sections of a capacitive element each having a capacitance value. The capacitor sections are provided in a plurality of wound cylindrical capacitive elements. Two vertically stacked wound cylindrical capacitance elements may each provide three capacitor sections. There may be six separately wound cylindrical capacitive elements each providing a capacitor section. The capacitor sections have a common element terminal. A pressure interrupter cover assembly is sealingly secured to the open end of case for the elements and has a deformable cover with a centrally mounted common cover terminal and a plurality of section cover terminals mounted at spaced apart locations. A conductor frangibly connects the common element terminal of the capacitor section to the common cover terminal and conductors respectively frangibly connect the capacitor section terminals to the section cover terminals. Deformation of the cover caused by failure of the capacitor element breaks at least some of the frangible connections sufficient to disconnect the capacitive element from an electric circuit in which it is connected. A cover insulation barrier mounted on the deformable cover, has a barrier cup substantially surrounding the common cover terminal and a plurality of barrier fins each extending radially outwardly from the barrier cup, and deployed between adjacent section cover terminals.
