  • APPARATUS AND METHOD FOR PERFORMING 3D PRINTING BY TAPPET DISPENSING
    Publication number: 20240066797
    Abstract: A 3D printing apparatus and method includes a piezo actuator that reciprocates a tappet. The reciprocation of the tappet generates pressure within a chamber filled with molten print material. The generated pressure causes the molten print material to be extruded through a nozzle coupled to the chamber. The piezo actuator is controlled to switchably provide continuous extrusion of print material or extrusion of discrete droplets of print material.

  • Security for integrated circuit microcomputer with EEPROM
    Patent number: 4698750
    Abstract: An integrated circuit microcomputer with EEPROM has a limited number of modes for operation. In at least first and second modes, the inner workings of the microcomputer, including the contents of the EEPROM, can be read externally from the microcomputer. An EEPROM security bit, when set, prevents the first mode from being entered and causes the EEPROM to be erased when the second mode is entered. The EEPROM is also erased if the security bit is erased.
