Title: Dynamic semiconductor memory including data control cell - has inverting cell type included in circuit with metal insulator semiconductor transistors (NL071276)
Inventor: ITO TSUNEO
IPC: G06F1/24
Filed: 1976-06-03
Abstract: The dynamic semiconductor memory has a data control cell (M11 to M15) which requires a constant initial state, a three metal insulator semiconductor storage cell (M16 to M19) and a preset stage (M1 to M9) which produces a preset signal during a given time interval by applying a power supply (VDD). The preset signal is passed to the input of the data control cell (M11 to M15) and cancels the storage state of the data control cell (M11 to M15). The drain electrode of a metal insulator semiconductor field effect transistor (MISFET M14) obtains the charge stored in the data control cell (M11 to M15). The source electrode is connected to earth and the gate electrode to the output of the preset stage (M1 to M3).

Title: Electric pulse amplitude measuring circuit - has adjustable threshold detector controlled by shorting triac as protector
Inventor: HERRMANN HELMUT ING GRAD
IPC: G01R19/165
Filed: 1976-06-15
Abstract: The circuit for measuring amplitude of pulses is protected by a triac (5) which ensures that peak voltages exceeding the set limit with the divider network (2) are not recorded. The shorting takes place without a delay line or a storage unit and thus enhances the safety of the sensing circuit. During the response of the surge control unit (1), a proportional voltage is fed to the peak sensing unit (4) and to the anode of triac (5) via divider (2) and protective resistor (3). Part of the voltage is transmitted to the electronic threshold detector (6). Excess voltage causes firing of the triac by switching amplifier (7), and therefore, the input of sensing unit (4) is shorted.
