Filed: 1973-10-11
Abstract: 1444164 Protecting transistors against overload SONY CORP 11 Oct 1973 [16 Oct 1972] 47558/73 Heading H3T [Alxo in Division G3] A protective arrangement for a power transistor comprises a voltage regulating circuit ineluding the power transistor as regulating element controlled by a differential amplifier to regulate an output voltage. Excessive load current is detected and causes the power transistor to be cut off. A temperature sensing circuit, including a control transistor, a diode and a Zener diode, also operates to cut off the power transistor when its temperature exceeds a given value. As shown, a series regulating power transistor Q 7  is controlled by a differential amplifier Q 8 , Q 9  through auxiliary transistors Q 5 , Q 6 . The amplifier compares the output voltage V OUT  sensed by a divider R 12 , R 13  with the voltage drop across Zener diodes D 4 , D 5 . Load current is sensed by a resistor R 14 , and when a limiting current is reached, a transistor Q 11  turns on. A further transistor Q 4  now becomes conductive, grounding the base of transistor Q 6  and blocking the power transistor Q 7 . A zener diode D 1 , with a positive temperature coefficient, forward diodes D 2 , D 3  with negative temperature coefficients, and a transistor Q 1  respond to increasing temperature of the power transistor Q 7  to increase the conduction of transistors Q 2 , Q 3 , turn on transistor Q 4 , and thus block the power transistor to prevent excessive temperature. The construction of diodes D 1 , D 2  and transistor Q 7  as part of a monolithic integrated circuit is described, Fig. 3 (not shown).

Abstract: 1,125,789. Pulse radar. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 24 Nov., 1965 [24 Nov., 1964], No. 49892/65. Heading H4D. The invention relates to the suppression of long echos e.g. clutter, in pulse radar returns by passing said return V through a threshold device S2 having an instantaneous threshold determined by the length of the echo present at the corresponding instant in the previous return. The return is primarily quantized in means S1 according to whether the amplitude is above or below a constant value and is also quantized in time by means of clock pulses t, each quanta being equal to the transmitted pulse width. Means S1 thus produces a train of 0 or #1 pulses of width t and grouped according to the originating echo. The #1 pulses arefed to advance a primary counter BZ. The clock pulses t are also fed to a range counter EZ which emits a pulse every eight clock pulses, causing the contents of counter BZ to be destructively read out to store SP. Thus for a short echo, the stored count will be short, but for a long echo, it will be large. The sorted count is read out of store SP exactly one repetition period less eight t later, is converted in means BN to an anologue form, and the analogue form used to control the threshold of device S2.
