A monolithic thick film inductor is made by printing alternating conductive layers and dielectric layers above one another, using the same dielectric printing screen and the same conductor printing screen for printing each of the dielectric layers and the conductive layers respectively. Each of the coil printing screen and the dielectric screen are indexed to n different positions in order to print each of the n layers. The resulting inductor includes a plurality of helical coil segments stacked above one another and electrically connected to one another to create the desired number of coil turns.

Method of making monolithic thick film inductor

A monolithic multilayer ultra thin chip inductor is manufactured with two terminals on the same end of the component to reduce the mechanical stresses caused by a coefficient of expansion mismatch. A third no-connect terminal located on the opposite end may be used to mount the component when a more rigid connection is required. The inductor is constructed using a bottom and top coil layer, each having a coil and forming a termination point corresponding to the inductor terminals. The opposite ends of the coils form connection ends and are electrically connected to form a continuous coil from one terminal to the other. Optionally, a number of intermediate coil layers can be included between the bottom and top coil layers. The coil layers are selected from a set of coil layers. As a result, the total number of coil turns can be obtained by selecting the appropriate coil layers.

A method of making a plurality of monolithic thick film components having multiple terminals comprising the steps of printing a plurality of components in a wafer form forming a matrix of components, printing holes in the matrix of components where two terminal ends meet thereby separating the terminals on each component, and dipping the terminal ends in a silver based thick film ink.

A monolythic multilayer chip inductor includes a plurality of subassemblies stacked one above another. Each of the subassemblies includes a ferrite layer having a coil conductor printed on its upper surface. All of the ferrite layers except for the bottom layer and a ferrite top cap include via holes therein for permitting interconnection of the electrical interconnection of the conductor coils from one layer to the other. One end of the top coil conductor is exposed adjacent the edge of the chip, and one end of the bottom coil conductor is exposed adjacent another edge of the chip so that the conductors can be connected to terminals for introducing electrical current which will pass through all of the interconnected coils.

The touch panel system of the present invention is adapted for use with a rectangular screen for locating an object placed adjacent the face of the screen. The touch panel includes first and second sources of directional beams, first and second movable beam deflectors positioned in spaced relation to one another, and being movable in a scanning pattern for causing the first and second beams each to be deflected in a scanning pattern which sweeps angularly in a predetermined sweep time interval across the face of the rectangular screen. A reflector is positioned around the screen in such a manner as to be in the path of the beams as they are deflected by the first and second deflectors, and being capable of reflecting the beams at an angle of 180.degree. with respect to the angle at which they strike the reflector. First and second scan detectors are used to detect the end of each sweep of the beams. First and second bend detectors are adapted to sense an interruption in the beams in response to the object being placed adjacent the face of the screen. A controller is connected to the scan detector and the bend detector for calculating the angular positions of the beams at the time they are interrupted by the object and for calculating the position of the object on the screen at that time.
