This invention is to provide a method and a system which, by making use of a stress luminescent material, renders it possible to directly observe a stress distribution on the base of a real time without electrical contacts, and to easily measure a stress or a stress distribution and a stress image. Essentially, the invention comprises the steps of adding a stress to a tested body containing a stress luminescent material whose light emission is proportional to the stress, making visually observable a stress distribution over the tested body in accordance with a luminous intensity of the stress luminescent material contained in the tested body, measuring the luminous intensity of the luminescent material of the tested body, comparing the measured value of the luminous intensity with certain correlation data indicating a relationship between the luminous intensity of the stress luminescent material and a stress, thereby obtaining a stress value or a stress distribution over the tested body.

The invention relates to a lingual bracket for correcting the position of teeth, comprising a bracket base, which can be secured on the lingual side to a front or canine tooth, and comprising a bracket body, the bracket having a slot, which extends in the mesial-distal direction, delimited on the lingual side as well as on the gingival and occlusal sides, and which is intended for accommodating an archwire. In order to develop the bracket in such a way that an archwire can be easily inserted into the slot, by which even relatively small directional forces may be reproducibly exerted on the tooth and the risk of root resorption can be kept low, the slot is delimited on the gingival side by the bracket base and on the occlusal and lingual sides by the bracket body. Furthermore, a bracket system comprising a front or canine tooth bracket of this type and comprising a side tooth bracket is provided.

A light pulse from an ultrashort pulse light source 11 is split by a beam splitter 12 and guided, to a detection medium 4, as an excitation pulse and probe pulse having respective predetermined linearly polarized states by an excitation optical system 2 and probe optical system 3, respectively. A light track region which is generated in the detection medium 4 by incidence of the excitation pulse, and in which the refractive index is changed by a nonlinear optical effect, is irradiated with the probe pulse. Of components which have passed through the detection medium 4, a probe pulse component whose polarized state has changed through the light track region is detected by a camera 53 via an analyzer 51 in a photodetection part 5. This realizes a light track observation apparatus capable of directly observing the light track of an excitation pulse.

A seal member to be contacted with an observation object is provided at an open end of a lens barrel so that the observation object can be attracted to the lens barrel via the seal member and fixed in direct and close contact with the lens barrel when a vacuum is created in the lens barrel by a vacuum pump. In other words, instead of providing a sample chamber, the observation object is fixed in close contact with the lens barrel to prevent relative movement therebetween by a suction force even without a sample chamber. In this configuration, the interior of the lens barrel can be maintained in a vacuum state despite the absence of a sample chamber and no adverse effect occurs during observation because the lens barrel and the observation object are not moved relative to each other by vibration.

The invention relates to a method and device for processing polarization-maintaining optical fiber pigtails in a non-melting point optical fiber gyroscope. The processing method includes preparing an array of optical fiber fixed blocks, a fixed axis of polarization-maintaining optical fiber pigtails, a polarization-maintaining optical fiber ring tail fiber together with an array of fixed blocks and an array of accompanying blocks. Grinding and polishing together and dividing the optical fiber fixed block array after polishing. The invention also provides an improved axis-fixing device for polarization-maintaining optical fiber pigtails. The end face processing is carried out on the same array fixed block together, instead of the traditional method of fixing the axis of a single optical fiber fixed block, which greatly improves the processing efficiency, makes the product consistent, and the process is simple. The card reduces the difficulty of card installation, and the end-face structure of the polarization-maintaining fiber can be clearly observed by setting an external light source and collecting images by a computer, which improves the axis positioning accuracy.

A machining tool comprises a frame mounting an extendable yoke slidable with respect to the frame in a first direction through one or more mounting pillars. A tool motor is mounted on the yoke. A drive mechanism for the yoke is also mounted in the frame, with a drive motor to drive the yoke drive mechanism. A belt is between pulleys on the drive motor and mechanism to transmit drive between them. A rotatable sleeve is around the tool motor and on which sleeve the belt engages on opposite sides of the tool motor, whereby the tool motor can extend between the drive motor and mechanism, thereby resulting in a compact arrangement of the tool.
