TITLE: The over-saturated transistor and its performance
PERIODICAL: Sd;lovaci technika, no. 12, ig6o, 449 - 451
TEXT: The article describes the performance-of a transistor-in impulse
operation, with special emphasis of delay time. The author~pointq~to a special.
case, not yet mentioned in literature, which~occurs, when:thcs emitted junction
with its recovery time t , behaves during the time-delay like amunsaturated
2
collector circuit. In response to an impulse, atransistor reacts'with a time
delay, caused by the surplus of minority carriers in.the base region. This time
delay is primarily determined,by the level of input signals., which cau.se the
oversaturation of the transistor, secondarily by transistor char.ActeIristics.~ To
calculate the time delay, it is essential to determine the'iinverise, parameters of.
the transistor. The response of an unsaturated transistor!to az~~impulse is.given
by an exponential equation which is generally applicable to leading and trailing
edges of the response pattern of the funation6f(co), which represents either a'
voltage or a current impulse. There is no substantial differende"in the duration

the circuit;. measurings were made at R =co. The time delay calculated accord-'~
ing to Equation 6 is 41.2,&zee, calculated according to Bquition;7 it is 49.6,~

that it is very sensitive with respect to theitTligger 'ing

connection between glucose and the dynamics of digestion: (a) a rise of bl6od:sugar
brings about an inhibition of digestive kinetics, and a fall of blood sugar reinforces
digestive kinetics (by tnodification of Lite excitability of the ali mentary centre). ~ (b)

Abstract New methods of investigating electro-optical phenomena in hydro-
phobe colloids (N. A. Tolstoy, P. P. Feofil6v, DAN,SSSR, 66,;:617,;
1949; N. A. Tolstoy, DAN SSSR, 100, 893, 1955) which are.based on
the study of the modulation of light passir~-perpieindicularly~to
the lines of an electric field through a planar condenser fed by
rectangular voltage impulses show that colloidal p~articles in,a-"
queous media possess rigid dipole moments of quit6ftonsiderable
magnitude. It is assumed that this rigid dipole moment is caused
by spontaneous orientation of water molecules ads6rb'ed on the sur-
face of the particle, which have arigid di~ole-~;The unipol~rity
(in the mean) of this orientation.permits one to~liken'the_ water'
film adsorbed on the particle to a surface piezoeiectric. The
present writers carried out similar experiments with aerosol,~ and
found that the electrooptical properties of!the mist can be per-,
fectly similar to the propel-ties of hydroph6be colloids. They
state that the establishment of the dipolarity of'mist particles'.
can possess significance for the explanation of the mechanism gov-
erning the aggregation of noncharged particles in~mists.
