Title: Controller for ac motor and controller for elevator
Inventor: MUTO NOBUYOSHI
IPC: H02P23/07
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To maintain high efficiency including a transient state even if a load applied to a motor is changed in any pattern by controlling a power converter so that the torque current component of a motor current and the exciting current component have the specified relationship based on a motor-current detecting means and a torque command. SOLUTION: The acceleration pattern from an acceleration-pattern generating means 11 is integrated by a speed-command generating means 120 and converted into a speed command. The speed command is introduced into the terminal of an adder-subtractor 130 on the adding side. The rotary angle speed of the rotor of an induction motor 60, which is operated in a speed operating means 121, is introduced into the terminal of the adder-subtractor 130 on the subtracting side. Thus, the speed deviation is generated. The speed deviation is inputted into a speed control means 140. The torque command of the speed control means 140 is inputted into an adder-subtractor 131. Meanwhile, the secondary magnetic flux from a current detecting means 150 is inputted into a generated-torque estimating means 152.  The instantaneous torque of the estimating means 152 is inputted into the adder-subtractor 131, and the torque operating amount is determined. Thus, the PWM inverter 40 is controlled.

Title: Optical prism
Inventor: NARUSE FUMIHIRO
IPC: G02B5/04
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To minimize the birefringence and limit a deformation due to environ mental changes by press-molding performs after preliminarily molding a thermo plastic resin with a saturated hydrocarbon ring into the preforms of prism. SOLUTION: Preforms 2a of prism which are of an almost approximate shape to the shape of an article of manufacture are formed by injection-molding an optical thermoplastic resin, preferably a thermoplastic resin with a main chain or a lateral chain having a saturated hydrocarbon ring. Further, these performs 2a are thermally molded under pressure using a specified mold and only the surface layer is melted and further, the prereforms 2a are press-molded to be shaped into prism articles of manufacture. Although the preforms of prism 2a to be obtained by injection molding need not be shaped to the accuracy which is too strict, the extremely inferior accuracy of the face results in the generation of an air pent-up in the surface of moldings during press-molding and the resultant extra labor required for enhancing the face accuracy.  For these reasons, it is advisable to reject the preforms 2a with the extremely inferior face accuracy and also obtain the preforms 2a with a press allowance (t) when the preforms 2a are press-molded.

Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To estimate the physical amount with high accuracy in a smaller calculation number of times without dividing a subject space excessively minutely, by dividing the object space into a plurality of areas, simplifying each area, and using a polynominal of transformation functions for every area. SOLUTION: A space-setting/space-dividing part 3 divides an object space into a plurality of areas on the basis of an inequality input through a man- machine(M/M) device 1. An area boundary condition-setting part 5 extends boundaries of divided areas and simplifies the outside of the areas. In the meantime, a transformation function-setting part 4 obtains a solution of the physical amount of each position within each simplified area to simplified boundary conditions of the area, and sets the solution as a transformation function. A polynominal-generating part 6 approximates the solution of the physical amount within each area by a polynominal of transformation functions having an unknown coefficient, and forms simultaneous linear equations from the generated polynominal with the use of mutual boundary conditions of areas input from the setting part 5.  An equation-operating part 7 solves the simultaneous linear equations and obtains the unknown in each polynominal, thereby calculating the physical amount of each position.
