  • Publication number: 20170030216
    Abstract: A dynamic system estimation device and method, whereby estimation for more performance parameters than there are sensors can be performed, the estimation taking temporal changes into account. The dynamic system estimation device includes: a prescribed number of sensors that detect prescribed observation values from a gas turbine engine; and a Kalman filter that uses a dynamic model of the gas turbine engine and estimates the state of the gas turbine engine, on the basis of the observation values detected by the sensors. The gas turbine engine includes an element having changes in temporal performance recorded by performance parameters. The Kalman filter enables more than the prescribed number of performance parameters to be estimated, as a result of introducing a first-order lag element in place of the element.

  • Patent number: 9459611
    Abstract: A wire electric discharge machine is configured to machine a workpiece by computing an electric current at the machining time before starting a main machining and compensating a power source voltage for machining. The wire electric discharge machine measures an average electric current and an electric discharge frequency at the machining time, in a measuring section in an approach before the main machining, and computes a peak current at the machining time. Further, an electric voltage of a machining power source is compensated by comparing the computed peak current at the machining, with a reference peak current.

  • Patent number: 9233429
    Abstract: Upper and lower wire guides in a wire-cut electric discharge machine are moved until a wire electrode contacts with a workpiece, and after the contact, the upper and lower wire guides are moved backward to a position A which is away from the contact point at a fixed distance. Then, the upper wire guide is moved until the wire electrode contacts with the workpiece and the upper wire guide is returned to the position A. Subsequently, the lower wire guide is moved until the wire electrode contacts with the workpiece and the lower wide guide is returned to the position A. A coordinate value on the position where the wire electrode contacts with the workpiece is calculated by using position detection values which are obtained in the above respective steps, and board thickness is calculated from the coordinate value.

  • Patent number: 9177527
    Abstract: A multiple primary color display device includes a plurality of pixels located in a matrix including a plurality of rows and columns. The pixels are each formed of at least four sub pixels for displaying different primary colors, which can be sorted into n number of virtual pixels, and use each of the n number of virtual pixels as a minimum color display unit for providing display. The sub pixels which form each of the virtual pixels include a sub pixel common to another of the virtual pixels. When a line having a width corresponding to the n number of virtual pixels is displayed, two sub pixels which are located at both of two ends, in a width direction, of the line and display a certain identical primary color to each other have a luminance lower than the original luminance that the two sub pixels.

  • Patent number: 9089914
    Abstract: A wire electric discharge machine has a function for controlling the machining liquid temperature. When it is predicted that the machining liquid temperature rises linearly, the machining liquid begins to be warmed at time t5b to reach machining liquid control temperature T2 at human operation beginning time t2. If the temperature rise at predetermined later time t8 is greater than predicted, temperature rising suspended from time t8 to a later time t9. Temperature rising resumed at time t9. This allows the machining liquid temperature to reach the machining liquid control temperature T2 without wasting electric power.

  • Publication number: 20150196964
    Abstract: A primary power supply charges a capacitor by turning on a switching element and, upon completion of charging, turns off the switching element. Then, an AC pulse voltage is applied to the gap between a wire electrode and a workpiece by alternately turning on and off a switching element present in a secondary power supply. After a dielectric breakdown occurs between the wire electrode and the workpiece, the switching element is turned on to connect the capacitor so that the capacitor supplies a pulse current for machining.
