Title: Controller for induction motor
Inventor: KUSAKA YASUSHI
IPC: H02P21/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To control the output torque of an induction motor accurately even in a region subjected to limitation by the power supply voltage. SOLUTION: In a region I of relatively low torque, an exciting current command Id* and a torque current command Iq* are varied along a maximum efficiency line and the output torque of an induction motor is controlled by (Id*, Iq*). In a region III of relatively high torque, output torque of the induction motor is controlled by Iq*/Id*, i.e., the slip, and a margin BC for the limit line due to limitation of power supply voltage is imparted with respect to the (Id*, Iq*). Terminal voltage of the induction motor is fixed at a level corresponding to the power supply voltage because the margin BC is imparted, and the output torque can be controlled accurately by the slip.

Title: Vibration damper
Inventor: SATO SHIGEKI
IPC: F16F13/00
Filed: 1988-01-20
Abstract: PURPOSE:To utilize sufficient vibration damping performance by detecting the pressure inside a primary chamber, applying a voltage to an electric rheological fluid inside an orifice according to the pressure variation state inside the primary chamber based on the detected data and controlling the applied voltage. CONSTITUTION:Based on the detected data of a pressure detector 14, a control means 17 is informed of the pressure variation state inside a primary chamber 4. According to the pressure variation state, a voltage is applied to the electric rheological fluid 13 inside the orifice 11 and said applied voltage is controlled. Based on the difference between the phases of both the supporting spring load of a resilient body 1 with respect to the relative displacement of a mounting member 3 and the extension spring load varying according to the pressure inside the primary chamber 4, the viscosity of the electric rheological fluid 13 flowing inside the orifice 11 is varied so that the load of the extension spring may be regulated quickly. As a result, forces generated inside a damper, including an internal force which varies inside the primary chamber 4 when the fluid moves between the primary chamber 4 and a secondary chamber 7 may be used effectively so that the sufficient vibration damping function operates.

Title: Method for continuously casting cast bloom and billet for spring
Inventor: SUGAWARA TAKESHI
IPC: B22D11/10
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To simultaneously reduce the inclusion in the surface layer part of a cost bloom and the dispersion of negative segregation by specifying size ratio of a long side and a short side in the cross sectional shape of the cast bloom, impressing the electromagnetic stirring in a mold, specifying the casting velocity and the cross sectional size and executing continuous casting. SOLUTION: The shape of the cast bloom is regulated to the round shape or to the rectangular shape having 1-1.5 size ratio of the long side and the short side. Successively, the electromagnetic stirring in the mold is impressed. At the time of regulating the cross sectional shape of the cast bloom to the rectangular shape, the continuos casting is executed so that the casting velocity in the relation with the cross sectional size satisfies the inequality Vc ×D<2> <=0.063. Wherein, Vc is casting velocity (m/min) and D is the thickness (m) of the cast bloom. On the other hand, in the case of regulating the cross sectional shape of the cast bloom to the round shape, the continuous casting is executed so as to satisfy the inequality Vc ×πR<2> <=0.063. Wherein, R is the radius of the cast bloom.  By this method, the stirring energy density density is secured by regulating the throughput quantity to a prescribed value or lower, and the floatabilitly of the inclusion in a mold can be improved.
