Title: Delta sigma modulation circuit for analogdigital converter
Inventor: SUZUKI TAKAO
IPC: H03M3/02
Filed: 1986-05-16
Abstract: PURPOSE:To make the title circuit immune from the internal noise of the circuit by providing an adder/correction circuit adding/correcting a binary quantizing signal and a binary correcting quantizing signal to output ternary state quantizing signal so as to suppress the internal operating voltage of the circuit to the same level as the input signal voltage. CONSTITUTION:The titled circuit consists of a delay device 42 retarding the 1st integration signal, a correction quantizer 46 deciding the polarity of the 1st integration signal a binary quantized correction signal OS 12 and the adder/ correction circuit applying addition/correction to a binary quantized signal OS 11 and the correction quantized signal OS 12 to generate a ternary-state quantized signal OS 1 and outputting the said signal as a digital output signal OS 1. Assuming the binary output of the 1st quantized signal OS 11 and the 2nd quantized signal OS 12 as (+1, -1), then the output signal OS '1' being the addition and correction of them is a ternary-state output (+1, 0, -1). Thus, the integration signal voltage of the 1st and 2nd integration signals, that is, the internal operating voltage is suppressed to the same level with respect to an analog input signal voltage, for instance.

Title: Optical modulation wavelength converter
Inventor: FUKUDA HIROAKI
IPC: G02F1/225
Filed: 1991-05-17
Abstract: PURPOSE:To generate and modulate a second harmonic wave by the same element by generating a surface acoustic wave to be propagated in the same direction as a guided light, mode-converting from a TE-mode to a TM-mode or vice versa according to presence or absence of the wave, and modulating the second harmonic wave by utilizing it. CONSTITUTION:When one of latticelike electrodes having an electrode structure 3 of a transducer is grounded and a voltage is applied to the other, a distortion is generated in a three-dimensional waveguide 2. In this case, when the applied voltage is vibrated by a frequency (f), a surface acoustic wave having the frequency (f) is excited in the waveguide 2, and propagated in a guiding direction at a phase speed (v). Here, when the wavelength of a basic wave laser light is lambda and equivalent refractive indexes of TE-and TM-modes are Nte, Ntm, if the frequency (f) and the speed (v) are so set as to become f=v.¦Nte-Ntm¦/lambda, the guiding of the guided light is synchronized with the propagation of the wave to perform a mode-conversion. Then, a misalignment of the phase of the generated second harmonic wave with that of the basic wave laser light is compensated for by a refractive index varying range 4 in which the refractive indexes are alternately varied at a period LAMBDA.
