Title: Optical modulator
Inventor: NAKAZAWA TADAO
IPC: G02B6/12
Filed: 1989-12-14
Abstract: PURPOSE:To eliminate a rise in modulation voltage or decrease in modulation band by forming curved parts at a branch optical waveguide part and generating an optical path difference between a 1st and a 2nd branch optical waveguide. CONSTITUTION:The curved parts 2a1 and 2a3 of the branch optical waveguide part are formed in an arc shape on both sides of parallel optical waveguide parts 2a2 and 2b2. The branch optical waveguide 2b has linear waveguides 2b1 and 2b3 on its branch point side and multiplexing point side and the optical path difference between the branch optical waveguides 2a and 2b becomes right a half wavelength, thereby forming the optical modulator which shifts in operation point by a half-wavelength voltage. Consequently, while the gap d0 between the parallel optical waveguide parts 2a2 and 2b2 of the center part of the optical waveguide 2 constituting an electrode formation part for modulation is held equal to that of symmetrical waveguide arrangement, the optical path length difference between the branch optical waveguides 2a and 2b can be varied, so the operation point of the modulator can be controlled widely without causing the increase in half-wavelength voltage nor deterioration in modulation band.

Title: Preceding vehicle detector
Inventor: YAMAMURA TOSHIHIRO
IPC: G01S17/88
Filed: 1992-11-10
Abstract: PURPOSE:To obtain the yaw rate of own vehicle accurately for obtaining the driving speed of a preceding vehicle needed for calculating a proper distance between vehicles. CONSTITUTION:With the entire average of radar detection data when own vehicle advances, distance data are reduced by the amount of traveling distance and an angle does not change. When the own vehicle generates yaw rate, angle totally changes by the same mount. Detection is made based on these characteristics by comparison with data for tau time before. DELTAthetam for maximizing the correlation function expression of G which is shifted by DELTAtheta in reference to F is obtained with a detection distance function for a sweep angle theta this time being L=F (theta) and a function where the detection distance for tau time before is compensated being L'=G(theta). The DELTAthetam is the yaw angle of the own vehicle which has changed and the yaw rate is obtained by dphi/dt=DELTAthetam/tau.
