Title: Nonlinear distortion reducing circuit of digital filter
Inventor: KASUGA MASAO
IPC: H03H17/02
Filed: 1979-07-03
Abstract: PURPOSE:To reduce nonlinear distortion generated in a multiplier, having the number of bits limited, in a digital filter only by adding a simple circuit. CONSTITUTION:A digital signal (m bits) arriving at input terminal 1 is supplied via input register 2 to delay unit 10, where it is delayed by not less than one sampling cycle, and its output is applied to shift register 14, which shifts it with shift pulses from detecting controller 11 in the MSB(most significant bit) direction to output an n-bit digital signal to multiplier 4. Here, it is multiplied by an n-bit digital signal from coefficient unit 3 to supply shift register 15 with a 2n-bit digital signal. Shift register 15 shifts the input in the LSB(least significant bit) direction with shift pulses from detecting controller 13 and an m-bit digital signal is obtained again and then applied to input terminal A of adder 5.

Title: Variable diaphragm device
Inventor: KURITA YOSHIO
IPC: G03B9/02
Filed: 1981-06-01
Abstract: PURPOSE:To change the area of an opening through which light passes simply with quick response by fitting plural ringlike electrodes to a substrate consisting of an optical material with photoelectric effects and applying voltage to the substrate selectively. CONSTITUTION:Plural ringlike electrodes 10, 11, 12- are fitted to both the sides of a photoelectric material substrate 1 and deflecting plates 3, 4 are attached so as to put the substrate 1 between them. In case of no voltage upon the substrate 1, incident light through the deflecting plate 3 is not transmitted as a projected light because of the interaction with the deflecting plate 4, but with the application of voltage, the deflecting surface on which voltage is applied is rotated and light passes through only the rotated part as a projected light. If the electrode 10, 11 are selected and voltage is applied to the parts for example, light passes through only that parts and the device acts as a diaphragm device with a circular opening of diameter r1.
