  • Patent number: 7035777
    Abstract: A wall-thickness thinning rate at a not-measured position is estimated using information having a small number of measured points. Simulation of behavior of fluid flowing inside a pipe line is performed based on wall-thickness data of pipes and three-dimensional layout data of the pipe line including the pipes using a computer, and simulated wall-thickness thinned data of the pipes composing the pipe line is calculated from change of the simulated behavior of fluid.

  • Publication number: 20060044737
    Abstract: A surface-mounting thin type capacitor includes a capacitor element having a shape of and two end portions which form a side surface of the capacitor element. Two anode terminals are disposed on lower surfaces of the end portions along the side surface to form a mounting surface substantially perpendicular to the side surface. A cathode terminal is disposed at a middle part of the capacitor element to form the mounting surface together with the anode terminals. The cathode terminal is not between the anode terminals spatially and thereby manufacturing process of the capacitor is simplified and it is easy to change the intended use of the capacitor.

  • Publication number: 20060009874
    Abstract: A monitoring device and a monitoring method for an injection molding machine, in which a trend chart is displayed on a common axis so that changes of set values of molding conditions and changes of measured values of monitoring items can be grasped correspondingly. A history of the measured values of the monitoring items is stored, and a change history of the set values of the molding conditions is also stored. An operator sets monitoring items and molding condition items to be displayed. In doing this, the operator sets a display range such that molding condition items having changed set values within the display range are displayed and selected. Alternatively, coefficients of correlation between the measured values of the selected monitoring items and the set values of the molding conditions are obtained, and the molding condition items are displayed in the order of priority of correlation and selected.

  • Patent number: 6972759
    Abstract: An image matching device for extracting differences between an image taken of an actual object and model data with high accuracy. The image matching device includes a model data storage unit for storing model data of a layout of component parts of a plant, an image data storage unit for storing, for example, data of images taken of the plant, a parts library containing data on parts, heat insulating material library containing information of heat insulating materials, a model correcting unit, and a matching unit. The model correcting unit produces, based on model data and parts data, synthesized image data of an image viewed from the same position and in the same direction as actual image data is obtained by taking a photo of the plant. The matching unit matches a synthesized image to a real image.

  • Publication number: 20050000115
    Abstract: A hard elastic body (10) having a longitudinally extending cavity (13) formed therein is provided mainly at a forefoot region (F) of a sole body. The cavity (13) is formed of a first curved surface (11) extending curvedly in a longitudinal direction and a second curved surface (12) disposed under the first curved surface (11) and extending curvedly in a longitudinal direction as well. A front and rear end of the second curved surface (12) is connected to a front and rear end of the first curved surface (11) respectively and an intermediate portion of the second curved surface (12) is spaced apart downwardly from an intermediate portion of the first curved surface (11). A path (PQ1) between the front and rear end of the first curved surface (11) is substantially equal to a path (PQ2) between the front and rear end of the second curved surface (12). When the first curved surface (11) is pressed downwardly, the sole body is deformed in such a way that a rear foot region (R) of the sole body is lifted upwardly.

  • Publication number: 20040187332
    Abstract: Methods and systems for realizing accurate coordinate measurement using a multi-joint measuring arm. A system includes a support member, a multi-joint measuring arm having a first end attached to the support member and a second end at which a probe can be installed, and a processor configured to produce a three-dimensional coordinate corresponding to a position of the probe based on an angle of each joint of the measuring arm. A parameter concerning a posture of the measuring arm is detected exceeding a prescribed value, and a user is warned in accordance with a result of the detection. The prescribed value has been determined, for example, in accordance with a probability that a measurement error due to a user action pulling the measuring arm away from the support member becomes out of an allowable range.

  • Patent number: 6799306
    Abstract: Layout of a high-speed signal wiring on a power supply plane is checked and specified at an optimum position capable of minimizing a spurious electromagnetic radiation so as not to affect other wiring layers. When a high speed signal line which is an object to be checked exists on a power supply plane, a perpendicular distance between the high speed signal line and the plane which is nearest to the signal line is determined, and compared with a minimum required distance computed therefor in advance on the basis of its circuit specification of the high speed signal line. If the perpendicular distance determined does not exceed the minimum required distance computed, an appropriate message corresponding to the name of the high speed signal line is displayed.
