Title: Rear wheel steering method
Inventor: MOMOSE NOBUO
IPC: B62D113/00
Filed: 1993-07-07
Abstract: PURPOSE:To dissolve a sense of incongruity at steering in case of computing an reverse phase rear wheel steering angle based on a prescribed factor and a front wheel steering angle by setting a prescribed factor so as no to generate a step change of rear wheel lateral speed against step steering and an inverse response phenomenon. CONSTITUTION:A controller 15 inputs respective detected signals such as a handle angle thetaH, vehicle speed V, yaw rate gamma, and an actual rear wheel steering angle into the input part 30, so as to judge the running mode of a vehicle in the judging part 32. The control signal SR of a rear wheel steering valve is computed in the control part 34, and output from the output part 35. The control part 34 obtains an antiphase rear wheel steering angle deltaR1by multiplying the handle angle thetaH by a value which obtained by dividing a first factor (a) by steering gear ratio rho at least in the antiphase computing part 51. In the addition part 53, a target rear wheel steering angle deltaR is obtained by summing up respective rear wheel steering angles of antiphase and in-phase. In this case, the first factor (a) is set so as not to generate the step change of rear wheel lateral speed against step steering and the inverse response phenomenon.

Title: Method and device for automatic welding
Inventor: MATSUMOTO TAKERU
IPC: B23K9/12
Filed: 1981-10-21
Abstract: PURPOSE:To weld thin sheets having flat parts and arc-shaped bulging parts automatically with high efficiency and high quality by moving a welding torch reverse around the perpendicular axis so as to make the angle of inclination thereof constant in the state when the welding torch descends toward the bulging parts. CONSTITUTION:A welding torch 34 is beforehand inclined with respect to a swiveling shaft 32, and when the torch arrives at a bulging part 41, the torch begins to weld the weld zones. A servocontrol motor 25 runs on changing of the arc voltage and a welding head 24 begins to ascend. Then a position detector 28 decelerates a motor 19 for traveling, thus maintaining the welding speed constant. At the same instant when the torch 34 arrives at the peak of the part 41, an air cylinder 37 operates to turn the torch 34 around the shaft 32 at a right angle to the advancing direction of welding with the plane inclusive of the peak and perpendicular to a flat part 13 as a symmetrical plane. In this state the torch 34 continues to descend and when the torch arrives at the transfer point 43 to the part 13, the air cylinder 37 operates to turn the torch 34 to the original inclined state, thus the welding in the weld zones of the part 13 is accomplished continuously.

Moreover, the signal is shifted by -2kHz and fed to 16kHz FIR filter, the signals (l), (m) are subject to 1/2 thinning to form a complex number signal (n). Finally, the signal is fed to an 8kHz operation IIR (cyclic digital) filter, and after the signal is shifted by 2kHz, the real part is taken to demodulate a signal (r) of the CH 4. Thus, FDM-TDM conversion is applied directly by a multiplex level to simplify the constitution of the converter.

Abstract: PROBLEM TO BE SOLVED: To make the cross-section of an optical waveguide to an approximate circular shape and to reduce the connecting loss to an optical fiber by opposing the respective oxidized regions of two specific optical waveguide members to each other and joining them together. SOLUTION: A mask layer 2 is film-formed on a silicon substrate 1.

Note that the process above is started from the section 2a in an approximately semicircular shape. Then, impurity is doped from the section 2a to form a core section 5. Then, the region 4 is oxidized by depositing the film containing impurity on the substrate 1 and process the film. At that time, the impurity is doped into the inner section of the region 4 from the film and the density gradient of impurity is made from the surface to the inner section to from the section 5.  Then, a clad section 6 is formed in the outer periphery of the section 6 which is not being doped.

Title: Reflection type optical modulator
Inventor: TAKEDA YASUHIKO
IPC: G02F1/035
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To easily enable the separation of only a signal light beam obtained by the simple constitution. SOLUTION: A part between the end face of a substrate 32 and a reflection film 74 is coated with an anisotropic refraction index film 72 by oblique vapor depositor as the reflection part 43 of this optical modulator and a sandwiched structure is formed. The anisotropic refraction index film 72 is deposited so that the optical axis is inclined by 45 deg. to the normal of the substrate and the thickness of the film is adjusted so that the phase difference between the polarization of light wave transmitted through the film in the direction of optical axis and the polarization in the direction orthogonal to the axis becomes ΠZ (function ing as a λ/4 plate). Consequently, the polarizing plane of reflected beams generated on the halfway boundary is not rotated and the only polarizing plane of the light beam from the optical modulator is rotated.  Since the reflection part 43 is composed of the double layer structure of the anisotropic refraction index film 72 and the reflection film 74, the modulator converts beams to the reflection beam generated on the halfway boundary and a signal light beam having the different polarizing plane.
