  • Publication number: 20170341581
    Abstract: A bird's eye view image is displayed to be recognized by an operator intuitively and precisely, irrespective of the displayed direction of the bird's eye view image. The display device has a plurality of cameras having optical axis directed obliquely downward to take images around a self-propelled industrial machine. A view point converting section converts the camera images to an upper view point to create bird's eye images, and an image composing section creates a composite bird's eye view image by composing respective bird's eye images around a symbol image of a dump truck. A direction superposing section superposes a forward direction indicator to indicate the forward direction of the dump truck on the composite bird's eye view image, and a monitor mounted in a cab of the dump truck displays the composite bird's eye image in an arbitral direction which is composited with the forward direction indicator.

  • Patent number: 7350404
    Abstract: The probe tip movement control method of the scanning probe microscope is used for a scanning probe microscope provided with a cantilever 21 having a probe tip 20 facing a sample 12. The atomic force occurring between the probe tip and sample is measured when the probe tip scans the surface of the sample. X-, Y-, and Z-fine movement mechanisms 23, 29, and 30 are used to relatively change the positions of the probe tip and sample. It is possible to maintain a high measurement accuracy and enable scan movement of a probe tip on a sample surface by simple control when measuring a part having a gradient in measurement of an uneven shape on a sample surface.

  • Publication number: 20070180889
    Abstract: A probe replacement method for a scanning probe microscope for measuring the surface of a sample, having a cantilever (21) having a probe (20), and a measurement unit for measuring a physical quantity between the probe and sample. The scanning probe microscope is provided with a cantilever mount (22), a cantilever cassette (30), an XY stage (14) and Z stage (15) for moving the cantilever cassette, and an optical microscope (18). In a first step, a cantilever is selected from the cantilever cassette and is mounted on the cantilever mount. In a second step, an optical microscope is moved and the mounted cantilever is set in a prescribed position in the field of view after the cantilever is mounted in the scanning probe microscope. In the second step, a step is provided for moving the optical microscope side or the cantilever side and performing positional adjustment.

  • Patent number: 7243441
    Abstract: A method an apparatus for measuring the depths of many fine holes formed in the surface of a sample by etching. Positional information on a plurality of hole patterns is acquired by scanning, with a stylus, the surface of the sample in which the hole patterns are formed by etching. The depths of the plurality of hole patterns are measured by scanning, with the stylus, bottom faces of the plurality of hole patterns and the surface of the sample in the respective vicinities of the hole patterns on the basis of the positional information that has been acquired. Information on distribution of the depths of the plurality of hole patterns is displayed on a screen on the basis of information on the measured depths of the plurality of hole patterns and the positional information on each of the hole patterns.

  • Patent number: 6317669
    Abstract: An automatically operated shovel has a shovel and an automatic operation controller arranged on the shovel to store by a teaching operation plural working positions of the shovel, which comprises at least a digging position, and also to cause by a reproduction operation the shovel to repeatedly perform a series of reproduction operations on the basis of the stored plural working positions. The automatic operation controller is provided with servo control means for outputting, as a servo control quantity, a sum of a compliance control quantity and a pressure control quantity. The compliance control quantity is obtained by multiplying with a stiffness gain a difference between a target position of each operational element of the shovel, the target position comprising angle information indicative of an operational target of the operational element, and a current position of the operational element, the current position comprising current angle information on the operational element.
