摘要： The invention relates to an electric injecting molder and an injection velocity and injection pressure controlling method for an electric injecting molder, and it is an object of the present invention to make it possible, in injection molding by an electric injection molder, to mold stable resin products having a minimized dispersion in the quality even if the operation environment varies. When an injection screw (23) disposed in an injection cylinder (22) is driven to move in forward and backward directions by an electric motor (29A) to inject resin material (3) in the injection cylinder (22) into a metal mold (1, 2) to fill the metal mold (1, 2), the electric motor (29A) is first velocity-controlled to fill the resin material (3) into the metal mold (1, 2), and, after the filling, the electric motor (29A) is pressure-controlled to replenish the resin material for shrinkage of the resin. Upon the velocity control, a velocity target value for the injection screw (23) is corrected in response to a force detection value so that the velocity target value for the injection screw (23) may decrease as the force detection value increases to perform velocity feedback control of the electric motor (29A) so that a velocity detection value from velocity detection means may be equal to the velocity target value.

摘要： PROBLEM TO BE SOLVED: To prevent generation of backlash and lost motion when working and feed a movable member at a high speed when feeding. SOLUTION: In working, one of two motors 11, 21 generates torque for moving the movable member GL and both the motors 11, 21 generate offset torque in a reverse rotation direction, so that generation of backlash and lost motion is prevented. In feeding, both the motors 11, 21 generate torque for moving the movable member GL in the same direction so that the movable member GL is operated for high-speed moving. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To allow molding a stable resin product without quality fluctuation despite change in work environment, in injection molding using an electric injection molding apparatus.
SOLUTION: The invention relates to an electric injection molding apparatus which injects and fills up a resin material, supplied to an injection cylinder, into dies 1 and 2, by back and forth driving an injection screw 23 equipped in the injection cylinder using a motor 29A. A control means 50A, which speed controls the motor 29A when filling the resin material in dies 1 and 2 and pressure controls the motor 29A when compensating post-filling resin contraction, is switched from speed control to pressure control, when pressure in dies 1 and 2 detected or presumed by an internal pressure detector reaches a predetermined pressure. This brings the pressure in the die, to a smooth and continuous state, thereafter to a gradually increasing condition, then to a raised medium-pressure state, and further to a gradual decrease afterward.

During speed control, the speed target value of the screw is corrected corresponding to a force detection value so that the speed target value of the screw decreases with the increase of the force detection value, and the motor is speed-feedback- controlled so that a speed detection value from a speed detection means is the speed target value.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus and a method, for the vibration test of a vehicle, wherein a target waveform is generated quickly and with high accuracy and various tests can be performed in a short period. SOLUTION: Target waves corresponding to the displacement in the vertical direction of a road-surface wave element are expressed by YT(t). Input waves which are input to an exciter are expressed by Xn(t) as nth-order compensation waves. Nth-order output waves which are output by the exciter are expressed by Yn(t). Xn is a function which is described by a linear combination on the basis of a first term containing Xn-1 and on the basis of a second term expressed by YT and Yn-1. A control signal based on two pieces of information on the target waves YT(t) and the output waves Yn(t) is combined with the input waves Xn(t), and especially a control signal by the linear combination is used repeatedly several times. Therefore, a plurality of motions in the vertical direction of a plurality of wheels in which action faces subjected intermittently and in parallel are physically influenced can be brought close to a target value quickly and asymptotically.

摘要： PROBLEM TO BE SOLVED: To provide a controller for multidimensional shaking table that can reduce the operating amount to about one-(n)-th as compared with a conventional optimal controller for shaking table. SOLUTION: A first subtractor 8, a distributed optimal controller 1 for shaking table, and a multidimensional shaking table system 3 are arranged sequentially.

A second subtractor 16 determines a shaker displacement difference vector signal 13 which is received by a servo controller 10 producing a shaker displacement command vector signal 14 being delivered to a multidimensional shaking table 9. Operation of the multidimensional shaking table 9 is controlled by a displacement command vector signal 7 from the distributed optimal controller 1 for shaking table.

摘要： PURPOSE:To prevent the hunting of an effective power output and a voltage applied to a coil and to prevent a bad influence on a power system. CONSTITUTION:A superconducting stationary energy storage apparatus is composed of an effective-power controller 1A, of a reactive-power controller 2A, of a control-mode changeover device 3, of a superconducting coil current limiter 4 and of a power changeover device 5. Then, the current limiter 4 outputs a limitation signal to the effective-power controller 1A and the reactive-power controller 2A when a current to the power changeover device 5 is limited. The effective-power controller 1A and the reactive-power controller 2A make inputs of integrators 13, 23 zero by the limitation signal from the current limiter 4, it sets the outputs of the integrator 13 to an effective power target value Ps, and it sets the output of the integrator 23 to a reactive-power target value Qs. Thereby, when the current limitation of a coil is released and returned again to the simultaneous control mode of an effective-power output and a reactive-power output, the effective power output P becomes equal to the effectivepower target value Ps, and the generation of hunting is prevented.
