Patent number: 6498712Abstract: A variable electronic component in the nature of a trimmed capacitor has a very low cost and simple design. A dielectric housing has an open end that a plug may be press fit into. The plug grips an upper region of the dielectric housing with at least one projection. A conductive body acts as a variable electrode, moving axially within the dielectric housing. A stator, acting as a fixed electrode, is securely affixed to an outer portion of the dielectric housing opposite the open end by crimping the top of the stator over a protrusion on an outer surface of the dielectric housing. The total press fit design reduces the number of steps normally required to make a trimmed capacitor, thereby reducing the cost of manufacture.Type: GrantFiled: March 6, 2002Date of Patent: December 24, 2002Assignee: Voltronics CorporationInventor: David Ditlya

Patent number: 5229911Abstract: A variable electronic component in the nature of a trimmer capacitor has greatly increased voltage rating and capacitance range, while eliminating possible failure modes. An annular opening formed in a stationary electrode is surrounded by plastic dielectric material so as to receive in interference fit a circular sleeve of an opposing impedance varying electrode. By filling the air gap with plastic dielectric material, no air contributes to the effective dielectric, while at the same time, preventing shorting as a result of loose metallic particles which might be present.Type: GrantFiled: June 4, 1992Date of Patent: July 20, 1993Assignee: Voltronics CorporationInventor: David Ditlya

Patent number: 5155654Abstract: A variable electronic component in the nature of a small sealed capacitor includes a pair of free floating dielectric plates disposed overlying a conductive body which is displaceable therebetween along a linear path. The conductive body is brought into varying degrees of overlapping registration with a conductive layer on the dielectric plates to vary the impedance characteristics of the capacitor between minimum and maximum values.Type: GrantFiled: May 30, 1991Date of Patent: October 13, 1992Assignee: Voltronics CorporationInventor: David Ditlya

Patent number: 4876627Abstract: A variable electronic component in the nature of a capacitor includes a free floating impedance varying member disposed overlying an impedance varying portion of a rotor. The impedance varying portion includes a substantially planar surface and an adjacent opening which are brought into varying degrees of overlying registration with the impedance varying member.Type: GrantFiled: April 6, 1989Date of Patent: October 24, 1989Assignee: Voltronics CorporationInventors: Martin A. Mittler, Kenneth J. Scowen

Patent number: 4764843Abstract: A variable electronic component in the nature of a trimmer capacitor for use in a subminiature electronic circuit is adapted to provide a desired wide range of impedance characteristics. The variable electronic component is constructed of a sealed housing having an impedance varying piston driven by a screw supporting a non-axially extending tab or threaded member. The piston includes a cylindrical member which, through conjoining with a cylindrical member of dielectric material, provides a varied range of capacitance to the trimmer capacitor.Type: GrantFiled: October 27, 1986Date of Patent: August 16, 1988Assignee: Voltronics CorporationInventor: Martin A. Mittler

Patent number: 4575779Abstract: A variable electronic component for use in a subminiature electronic circuit and adapted to provide a desired range of impedance characteristics. The variable electronic component may take the form of a variable trimmer capacitor, a variable resistor, and the like constructed to include an eccentric whose rotational motion imparts reciprocal movement to an impedance varying member. The eccentric is operative by engagement with an implement such as a screwdriver and the like.Type: GrantFiled: May 23, 1984Date of Patent: March 11, 1986Assignee: Voltronics CorporationInventors: Martin A.
