Title: A displaying system
Inventor: MIGOSHIBA SHIGEO
IPC: G09G3/28
Filed: 1982-07-21
Granted: 1988-10-17
Abstract: Radiation generated transiently at the start of discharge i.e. townsend discharge is used to provide high efficiency light transmisson.  Upon appreciation of the voltage a spike current flows through the discharge cell.  Along with this current, both electron temp. and emission intensity exhibit sharp peaks.  In this first period both townsend discharge and emission occur.  The current, then, decreases gradually.  In this second period, both electron temp. and emission intensity first drop and then increase gradually towards the steady values.  The electron density increases in both the first and second periods.  When the applied voltage is cut off the discharge current gradually reaches zero while discharging stray capacitances.

Title: Differential amplifiers with balancing compensation circuit
Inventor: DIJKMANS EISECAREL
IPC: H03F1/48
Filed: 1982-12-06
Granted: 1990-10-06
Abstract: A differential amplifier with single ended drive includes a balancing impedance (20) coupled between the base of the transistor (3) connected to the signal input (1) and the common point (9) of the two emitters of the transistors (3,4) which form a differential pair. The capacitance value of the capacitor (20) is equal to the capacitance value of the stray capacitance (19) of the collector-substrate junction of a transistor (10) which forms a current source. This provides a symmetry of the capacitances between the input (1) and the common point (9) and between the common point (9) and ground via the transistor (10). This results in an improved balance in the output signals at the output terminals (5,6) and a flat frequency response of the differential amplifier for higher frequencies.
