Title: Bent optical waveguide
Inventor: SAWANO ISATAKE
IPC: G02B6/12
Filed: 1987-10-15
Abstract: PURPOSE:To suppress the loss of radiation by forming a magnesium oxide diffusion part obtained by diffusing magnesium oxide along the bent outer peripheral part of a bent optical waveform formed by diffusing titanium metal to the surface of a lithium niobate substrate. CONSTITUTION:The optical waveguide 1 is formed by diffusing Ti metal to the surface of the lithium niobate 2 as a required pattern and the optical waveguide 1 is constituted of a straight optical waveguide 11 and a bent optical waveguide 12 continued to the waveguide 11 with radium R of curvature. The magnesium oxide diffusion part 4 obtained by thinly diffusing magnesium oxide is formed on an area along the outer peripheral part of the bent optical waveguide 12. Although a specific refractive index difference DELTAn of Ti diffusion to lithium niobate is a positive value, that of Mg diffusion is a negative value, so that equivalent refractive index distribution on the cross section A-A'-A'' of the waveguide 12 is not symmetrical about its center axis C, but an incident wave 3 made incident on the waveguide 11 does not change its waveform so much also at the time of propagating the waveguide 12 and a radiated component is extremely reduced. Thus, the radius of curvature of the optical waveguide can be reduced and a high density optical integrated circuit can be attained.

Filed: 1984-12-07
Abstract: PURPOSE:To obtain a vertical profile correction circuit where the hardware of a delay circuit especially is decreased remarkably by applying the 2nd differentiation processing after the bit rate is reduced by a signal converting circuit after the 1st differentiation processing. CONSTITUTION:An analog video signal AVS is quantized by an A/D converter 20, where the signal is converted to a digital signal v0. The digital video signal is subjected to 1st differentiation vertically by a 1H delay circuit 21 and a subtractor 22, and an output D1 is inputted to an LPF23. The LPF23 applies the band limit to the output of nearly 1.5MHz and the data is extracted once per four times by an interleaving circuit 24.

In applying the primary differentiation vertically twice in this way, since the LPF23, the interleaving circuit 24 and the limiter 25 are inserted between the 1st and 2nd differentiations, the quantity of hardware of the delay circuit 26 is reduced.

Abstract: PURPOSE:To prevent seizure or binding in a brake friction member and a vapor lock, etc., by prohibiting any braking operation when brake operating frequency becomes more than setting value, in the case of traction control which operates a brake at the time of driving slip detection. CONSTITUTION:In the case of traction control which operates a brake upon receiving a signal out of a driving slip detecting means detecting a driving slip of a wheel and prevents the slip from occurring, brake operating frequency is detected by a braking frequency detecting means, and when the frequency becomes more than the setting value, any brake operation is prohibited.
