Abstract: To achieve high adding speed in the presence of the transmission signals after only one gate delay time per stage (j = 0...n-1), it contains a first AND gate (11j) the input of which is fed with the two position signals Aj, Bj, and a second AND gate (22j) which is fed with the carry signal (Ci) of the next-lower stage (i). The two AND gates (11j, 22j) are in each case a component of a first complex gate (1j) for forming the sum and of a second complex gate (2j) for forming the carry. These contain a first and second, respectively, OR gate (15j, 25j), a third and fourth, respectively, AND gate (13j, 24j) and a first and second NOR gate (16j, 26j), at the respective output of which the inverted sum signal and, respectively, inverted carry signal (Sj, Cj) occurs. The respective three inputs of the first AND and of the first OR gate (11j, 15j) are fed with the two position signals (Aj, Bj) and the carry signal (Ci) of the next-lower stage (i) whilst the respective two inputs of the second AND and of the second OR gate (22j, 25j) are fed with the position signals (Aj, Bj). The two inputs of the third AND gate (13j) are connected to the output of the first OR gate (15j) and, respectively, to the output of the second complex gate (2j) whilst the two inputs of the fourth AND gate (24j) are connected to the output of the second OR gate (25j) or, respectively, fed with the carry signal (Ci) of the next-lower stage (i). The output of the first and that of the third, or of the second and that of the fourth AND gate (11j, 13j; 22j, 24j) is in each case connected to one of the two inputs of the first and, respectively, the second NOR gate (16j, 26j). In the lowest stage (0), the carry input of the first NOR gate (150) is omitted, the first complex gate (10) only consists of the first NOR gate (51) and of a NAND gate (160), and the second complex gate (20) is a NAND gate. The position signals and the carry signal of the next-lower stage (i) must be alternately applied directly or, respectively, invertedly in two successive stages (i, j). Resistance-connected depletion-type transistors can be used as load resistors (L1i, L2i) of the two complex gates (1i, 2i). <IMAGE>

Abstract: In a reflecting type overhead projector, a reflecting table is formed of a Fresnel lens and a mirror laid together with the mirror lying close under the lens, and the original is laid against and above the lens. A lamp above the reflecting table projects light towards the original. A projection lens above the reflecting table projects an image of the original upon the screen. A photosensitive element near the reflecting table responds to the light from the lamp. A control circuit receives a signal from the photosensitive element and controls the intensity of the light emitted by the lamp. The control circuit supplies full power to the lamp, lighting it more brightly, when first the lamp is to be turned on. Thereafter, when the lamp is being supplied with full power so as to light it more brightly, and then the intensity of light radiation received by the photosensitive element drops substantially, the control circuit supplies part power to the lamp so as to light it less brightly; and, when the lamp is being supplied with part power so as to light it less brightly, and then the intensity of light radiation received by the photosensitive element rises substantially, the control circuit supplies full power to the lamp so as to light it more brightly. Thus when the operator's hand is put under the lamp the lamp is dimmed; and thus the danger of the operator being burnt by the light from the lamp is avoided.
