  • Patent number: 4772867
    Abstract: A precision resistance network of individual resistances R.sub.i, especially for thick-film hybrid circuits includes an integrated structure formed of an electrically insulated substrate, having an electrically conductive film of constant thickness d applied thereto, the electrically conducted layer having a surface resistance (R.sub.S) exclusively dimensioned as a function of the individual resistances (R.sub.

  • Patent number: 4243969
    Abstract: A layer resistor element for use in a variable resistor has two resistance layers disposed upon each other on an insulating substrate, the lower resistance layer being provided with two comb-like sets of separating slots extending from opposite sides to form a meander-like resistance path, the widths and lengths of the meander turns varying in accordance with a given non-linear resistance characteristic. The upper resistance layer which is of a material of higher resistivity than the lower resistance layer covers the lower layer partly or totally and extends beyond the lower layer at one side thereof where it provides a path for a slider of the variable resistor.
