A specially shaped coil assembly for accurate adjustment of the magic angle is provided to permit accurate adjustment of an angle made between the direction of a static magnetic field and the axis of sample spinning without impairing the resolution of NMR signals. The sample is placed within the external static magnetic field B. The coil assembly is for use in a solid-state NMR apparatus that performs NMR detection while spinning the sample about an axis tilted at the magic angle relative to the external static magnetic field B. The coil assembly comprises a pair of arcuate conductor lines and a pair of straight conductor lines. Each of the arcuate lines has a diameter of 2a. Each of the straight lines has a length of 2L. The diameter 2a and the length 2L are so selected as to satisfy the relationship: 1.91&#x2264;2L/2a&#x2264;2.15.

Coil assembly for accurate adjustment of magic angle in solid-state NMR apparatus and method of adjusting magic angle using such coil assembly

A method of displaying sensed displacement is such as to collect single dimension light distribution data using a single dimensional imaging device; transmit the light distribution data to a processor; and display the light distribution data as a line bright wave form on a display using software implemented by the processor.

Displacement sensor having a display data output

An image taken by an imaging device is displayed on a display unit. When a confirmation instruction is inputted through an input unit, image teaching is performed while the image displayed on the display unit is set to a setting object image. A measurement item which is of a candidate of a measurement process including specification of a reference position is displayed as the measurement process to accept selection. Specification of cutout area which constitutes one measurement target region is accepted, a measurement point including a local region or a feature point which is used for the measurement is automatically set in the measurement target region based on pieces of information on the set measurement process and reference position.

Displacement sensor

Provided is a displacement sensor which allows at least part of the data used from the time of obtaining an image until the time of computing the displacement can be readily verified. In a displacement sensor for automatically extracting a coordinate of a measuring point from an image obtained by using an imaging device according to a prescribed measuring point extraction algorithm, and computing a desired displacement from the automatically extracted measuring point coordinate, the sensor is further provided with the function to edit data used from the time of obtaining the image until the time of computing the displacement for use as display data for an image monitor.

An optical displacement sensor takes in a plurality of images of a target object by projecting a slit beam of light and using a two-dimensional image taking element by changing the image taking conditions each time. Parameters defining these conditions affecting the brightness of the obtained image are varied. From each of these images including an image of a portion of the sectional contour line of the target object, a segmented image satisfying a specified maximum brightness condition is extracted and a synthesized image is generated by gathering such segmented images. The target object is inspected from such synthesized image.

Optical displacement sensor

Provided is a visual displacement sensor which comprises a laser diode ( ) for impinging a line beam onto an object to be measured at a prescribed angle, a two-dimensional CCD ( ) for monitoring the object to be measured, on which the line beam is impinged, from a different angle, measurement object range defining means for defining one or more than one measurement object range (K , K ) within a field of view of the two-dimensional CCD, measurement point coordinate determining means for determining one or more than one measurement point coordinate (A ) contained in the defined measurement object range according to an image captured by the two-dimensional CCD, and displacement measuring means for measuring a desired displacement according to the determined one or more than one measurement point coordinate.
