Abstract: A process for the manufacture of a multilayer ceramic substrate includes fabricating the multilayer ceramic substrate from a monolith fabricated from universal layers and a monolith fabricated from custom layers. The universal layer monolith and the custom layer monolith are then joined to form the complete structure of the MLC substrate.

Abstract: A driver circuit for a capacitively loaded line employs the charge storage capacitance of a diode for raising the base of a driver transistor above the circuit power supply voltage level so as to pull up the line to within a transistor base-emitter voltage drop of the power supply voltage level. The driver is easily fabricated in integrated circuit form, as no capacitors, either on or off chip, are required.The driver circuit includes a driver transistor, the collector of which is connected to the power supply and the emitter of which is connected to the line. A switching transistor has an input voltage applied between its base and emitter. A diode is connected between the switching and driver transistors, the anode being connected to the base of the driver transistor, and the cathode being connected to the collector of the switching transistor.

Abstract: This current switch driving circuitry, particularly for, but not necessarily limited to, inductive device current switching, comprises a pair of output transistors constituting a driving transistor for turning ON a subsequent switching transistor and a current sinking transistor for turning OFF that switching transistor with circuit provisions for maintaining the two transistors in a low power consuming standby state. A pair of receiver circuits are arranged for applying ON and OFF logical signals individually to the two transistors by way of intermediate circuitry having current multiplying circuitry for deriving the necessary driving power with a minimum of power consumed.
