Totally six polarization-maintaining optical fibers having the same beat length are arranged at both ends of a single-mode optical fiber and both ends of a single-mode optical fiber coil, respectively. An angle between a principal axis of polarization in a first polarization-maintaining optical fiber and a plane of polarization of linearly polarized light from a light source is 45 degrees. The optical length of each of the six polarization-maintaining optical fibers is larger than a coherent length of the linearly polarized light from the light source. The total of the optical lengths of the six polarization-maintaining optical fibers into which polarization rotation in the process of passing through the single-mode optical fibers is factored is larger than the coherent length of the linearly polarized light from the light source.

A learning unit in learning mode generates a cluster from a cluster analysis of data formed from frequency constituent data and state data, obtained from a sensor unit. An abnormality calculation unit computes, as abnormalities, the minimum values among distances to surfaces of the clusters of the data formed from the frequency constituent data and the state data, obtained when in predictive fault indicator sensing mode. A predictive fault indicator determination unit determines a predictive fault indicator of an X-ray tube by comparing the abnormalities with a predetermined threshold.

A display control device includes: a transparent color information storage unit that stores transparent color information; a run-length counter that calculates a run-length specifying the number of consecutive pixels having the same color information; a combination calculation unit that combines the image data for the plurality of display layers; and a combined image display unit that outputs the combined image data to a display device. If the color information for a total of run-length pixels calculated by the run-length counter is a transparent color, the combination calculation unit performs combination by ignoring the image data for the total number run-length of consecutive pixels.

A vibratory gyroscope including a vibrator () integrally having a plate-like body portion () spreading along a reference plane, three drive arms () extending in a first direction from the body portion along the reference plane, and two detection arms () extending in a second direction opposite to the first direction from the body portion along the reference plane. The three drive arms are composed of two exciting drive arms () that are excited in mutually opposite phases in the reference plane and a non-exciting drive arm () located between the two exciting drive arms. Each of the three drive arms has an arm width in a width direction along the reference plane and perpendicular to the first direction. Each of the two detection arms has an arm width greater than that of the drive arm in the width direction, thereby suppressing generation of vibrations along the reference plane.

An image forming apparatus has an image forming unit and a film-heat-type fuser over which a sheet with an unfixed toner image passes and on which are positioned a first temperature-measuring device centered on the fuser so that a sheet always passes over that device and a second temperature measuring device disposed away from the center so that large sheets will pass over the second temperature measuring device and small sheets will not pass over the device when being conveyed correctly. The device also has a temperature control mechanism, a sheet size detector and throughput control, so that the throughput control changes throughput when the sheet size detector determines that a small sheet is being conveyed and the difference between the temperatures of the first and second temperature measuring devices is less than a predetermined value as the sheet passes over the fuser.
