摘要： PROBLEM TO BE SOLVED: To prevent the teeth of a drive unit from cutting into the teeth of a screw shaft at the terminal part of a locating device. SOLUTION: A first screw part 6 is formed as the screw shaft 2 on a part excluding both ends and a second screw parts 7, whose screw thread diameter is smaller than that of the first screw part, is formed in each end of the first screw part 6. A female screw is attached as a rack part 3 to be engaged with the first screw part 6 of the screw shaft 2 so that it is driven linearly with the rotation of the screw shaft 2, and in addition, a leaf spring part 5 is attached to press the rack part 3 toward the screw shaft 2 side. Accordingly, when the rack part 3 comes to both ends of the screw shaft 2, the engagement of the second screw part 7 and the female screw of the rack part 3 is loosened because of the elastic deformation of the leaf spring part 5.

摘要： PROBLEM TO BE SOLVED: To solve such problems that a conventional nondestructive examination of false teeth is proposed by using X-rays or ultrasound and does not make an accurate evaluation and that images of surfaces and internal parts of the false tooth are not obtained especially in an non-invasive and simultaneous manner since the secular variations of the false tooth on which repair or lining are performed are determined by the status inside the oral cavity of a wearer or doctor's questions/a visual inspection and are not evaluated by objective evaluation methods.
SOLUTION: This invention provides an apparatus for making an evaluation inexpensively and instantly by using OCT or optical coherence tomography and the method for obtaining damage of the internal part of the false tooth by an image in order to contribute to dental treatments and for evaluating by capturing three-dimensional images of the false tooth by using the method when manufacturing the false tooth or at a place of adjusting to fix the false tooth.

摘要： PROBLEM TO BE SOLVED: To enable vibrations at multiple detection points to be detected in a range up to a high-frequency band by using an optical fiber.
SOLUTION: Light of a wavelength-variable laser 11 is branched by using optical couplers 13, 15 and 18, and applied to a plurality of sensor sections S1, S2 and Sn. The sensor sections have reflecting plates 23, 26 and 29 respectively, each varying its refection point in accordance with the vibrations. Interference properties of etalons of the plurality of sensor sections are previously varied for respective sensor sections. The laser light of the wavelength-variable laser is scanned in a fixed wavelength range, and applied to the sensor sections, thereby obtaining a superimposed interference signal corresponding to the properties of the etalons. A photoelectric conversion and a Fourier transform are applied to this signal, and its frequency is separated in accordance with the etalon properties of the sensor sections, whereby signals of the sensor section at the multiple points can be detected.

摘要： PROBLEM TO BE SOLVED: To provide a small-sized, inexpensive optical switch which is used for an optical multiplex communication system etc. SOLUTION: On a base 2, optical fibers 11 to 14, a cylindrical lens 4, and an MEMS substrate 5 are arranged.

摘要： PROBLEM TO BE SOLVED: To provide an optical tomographic image displaying system capable of displaying an image with a high resolution and a high sensitivity in a wavelength scanning type optical coherent tomography.
SOLUTION: An interference optical meter and a wavelength scanning light source 10, which periodically varies its oscillation wavelength, are employed. A reflecting object is disposed at a measurement position, and an A/D conversion is applied to an optical interference signal at even time intervals, and data numbers of timings when a peak and a bottom appear, are calculated by using a least-square method. Then, an approximate expression is derived based on above results by using a polynomial approximation, and the numerical sequence is calculated which consists of numbers of power of two obtained by converting the data numbers so as to be spaced evenly in frequency. Next, an object to be measured is disposed at the measurement position, and the number of data sets required for an FFT are calculated from measurement data at respective timings in this period by using a linear approximation, and a Fourier transform is applied to an optical beat signal which is obtained by an optical interferometer, at even frequency intervals, thereby obtaining the tomographic image.
