Title: Rear-wheel steering system in vehicle
Inventor: AKITA TATSUYA
IPC: B62D6/00
Filed: 1991-03-31
Abstract: PURPOSE:To improve the turnability at the time of a start of handling a steering wheel as well as to secure the stability at time of its handling back. CONSTITUTION:A steering ratio thetaS is determined by the following equation, if most desirably. In this equation of thetaS=C1+C2.¦thetaH¦-C3.¦dY¦, C1 is a fundamental characteristic item, thetaH a handwheel steering angle, dY a yaw-rate variation, and C2, C3 the control gain, respectively. C1-C3 are settable as a function making, for example, car speed a parameter. A steering angle characteristic item functions as a component for increasing a phase quantity, and a yaw-rate variation characteristic item functions as a component for decreasing the phase quantity the other way. Since a yaw-rate variation dY is followed well in response to operation of a steering wheel and varied, turnability at its handling start is improved, and at time of handling the wheel back, a phase quantity decreasing action goes down, thus stability is secured. In addition, a steering angle characteristic item improves yet more the stability at time of the handling back.

Title: Damping device
Inventor: NOMICHI TOSHIYUKI
IPC: E04H9/02
Filed: 1989-04-14
Abstract: PURPOSE:To damp the oscillation of a structure in the horizontal direction by means of wave motion in a tank as well as to damp the rocking oscillation including oscillation in the vertical direction by means of fluid and elastic support means by supporting a storage tank with an open fluid surface by a rocking fulcrum at the center section in the wave motion direction, and also by elastic support means at both end sections of the tank. CONSTITUTION:When a structure 1 oscillates horizontally to the directions A and B, and is also effected by rocking oscillation having a vertical component to the directions E and F by earthquakes, wind and the like, fluid 7 in a tank 3 starts to wave to the directions A and R while being excited by the oscillation of the structure 1. This therefore permits the oscillation of the structure 1 to be absorbed by the wave motion energy of the fluid 7. The bottom surface of the tank 3 at the both sides of a rocking fulcrum 5 are out of balance in pressure owing to the wave motion of the fluid 7, the tank 3 thereby starts to be rocked to the directions C and D about the rocking fulcrum 5 via elastic support means 6 and 6 at the both sides in the directions A and B. This causes reaction from each support means 6 to be acted onto the structure 1 to the directions E and F accompanied with oscillation, thereby damping the rocking oscillation of the structure 1 by means of the mass damping effect of the fluid 7 and the support means 6.

Title: Exciting system of fan-shaped beam array antenna
Inventor: NAKAJIMA NOBUO
IPC: H01Q21/22
Filed: 1983-05-31
Abstract: PURPOSE:To obtain a fan-shaped beam array antenna having the equivalent directivity to a conventional antenna of the same type with half number of elements, by exciting each radiation element so that the exciting amplitude of the i-th radiation element satisfies a prescribed equation for an optional train of an array antenna which produces a fan-shaped beam. CONSTITUTION:N units of radiation elements are arrayed on a straight line with a fixed interval to form an array antenna, and the exciting amplitude of each radiation element is set at ai (i=0-N-1). As a result, a radiation pattern of the direction of angle theta to the main radiation direction is shown by a function F(theta). Then a function F'(theta) is obtained by a malformation given by making use of a fact that the sine value to the angle (theta) is small and can be ignored to the cosine value in the front direction, i.e., within a fan-shaped beam. Therefore ai=2bi is obtaind for the amplitude ai to the conventional exciting amplitude bi. An equation is obtained from said ai=2bi and the function F'(theta). Thus an array antenna which is excited with the amplitude obtained from said equation can obtain the radiation characteristics equal to those of a conventional antenna with just half number of radiation elements.
