IPC: G03B7/085
Filed: 1966-10-03
Abstract: 1,163,768. Exposure control for cameras. KORARU K.K. Oct. 3, 1966 [Nov. 6, 1965; May 27, 1966; July 12, 1966; July 13, 1966; July 14, 1966; July 19, 1966], No. 44012/66. Heading G2A. An automatic exposure control for photographic and cinematographic cameras includes a Wheatstone bridge network included in a transistorized control circuit, one branch of the bridge circuit including a photo-resistor subjected to scene light through the objective lens, such that unbalance of the bridge causes an electromagnetic device, to actuate a diaphragm control to restore the balance. As shown, a photo-resistor 10, Fig. 1, receives light through lens 2, diaphragm 7 and lens 8. The photo-resistor 10 is included in one branch of a bridge circuit Fig. 4 (not shown), such that on a change of incident light on the photo-resistor the bridge is unbalanced between points (A and B). The bridge also includes a variable resistor (25) which is set according to the emulsion speed of the film 12, Fig. 1, and a resistor (27, Fig. 4, not shown) for setting shutter speed. Upon unbalance of the bridge circuit current flows through an energizing coil (L1) in the direction of the dotted line, thus causing rotation of coil 16, Fig. 3, which adjusts diaphragm 7. The coil 16 also carries a damping coil Lz which upon rotation generates a voltage of opposite polarity to that between points (A and B) Fig. 4 (not shown) of the bridge circuit. The damping coil L2 is stated to provide a constant current flow through the energizing coil L 1 to provide a constant speed movement and instantaneous stopping thereof when the bridge becomes balanced.

Title: Compensated electronic voltage source
IPC: G05F1/56
Filed: 1974-10-11
Abstract: 1446796 Automatic voltage regulation MOTOROLA Inc 11 Oct 1974 [20 Dec 1973]  44241/74 Heading G3X A regulated voltage source for ECL logic circuits includes a transistor circuit supplying a voltage with a predetermined positive temperature coefficient to the base of a shunt regulator transistor connected to an output transistor. The collector of the shunt transistor is connected to a circuit for compensating variations in the base-emitter voltage of the transistor which occur when the source input voltage varies. As shown in Fig. 2, the value of a resistor R2 and the junction areas of transistors T1, T2 are chosen so that the currents I1, I2 in each transistor are equal and a temperature dependent voltage related to the difference in base-emitter voltage 5 of the transistors is produced at the collector of transistor T2. The currents I1, I2 are input voltage independent due to the circuit inter-connections, and a regulated voltage V1 is therefore produced across a transistor T4 relative to the earth line 10. A second output voltage V2, relative to input line 11, is also made independent of input voltage by including in the circuit diode-connected transistors T7, T8 which compensate for variations in the baseemitter voltage of transistor 76 which acts as a shunt regulator. In another embodiment, Fig. 3 (not shown) transistor T7 is replaced by a further transistor (T9) connected between the bases of transistors T6 and T3. A further embodiment, Fig. 4 (not shown), uses an additional shunt transistor (T10) to compensate for variations in the voltage of transistor T6. Resistors (R9, R10) may be included to convert the circuit from a zero temperature coefficient supply to one with a desired coefficient complementary to that of the circuit to which the output voltage is to be supplied.
