摘要： This torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body comprises a band-form metal plate and is bent approximately into a C-shape along the circumferential direction of a motor shaft and a lock holder. The spring-form part is formed so as to be capable of radial elastic deformation. The spring-form part is configured from main protrusions arranged in a compressed state between the motor shaft and the lock holder, and from sub-protrusions arranged in a non-compressed state. Further, grease is stored in a part or all of the concavities formed by the main protrusions and the sub-protrusions.

摘要： Provided is an observation device which can obtain a phase image of a moving object rapidly with high sensitivity even when using a photodetector having a slow read-out speed per pixel. The observation device 1 comprises a light source 10, a first modulator 20, a second modulator 30, a lens 40, a beam splitter 41, a photodetector 46, and an arithmetic unit 50. The lens 40 receives scattered light generated by a moving object 2 and forms a Fourier transform image of the object 2. The photodetector 46 outputs data representing a sum in a v direction of data temporally changing at a frequency corresponding to a Doppler shift frequency of the light having reached each position on a light-receiving surface through the lens 40 at each position in a u direction at each time. The arithmetic unit 50 obtains an image of the object 2 according to the output of the photodetector 46.

摘要： A laser beam L1 emitted from a laser source 10 is projected onto a target 30 set in a vacuum chamber 60 while being focused by a focusing optical system 20. This results in generating fast particles P such as protons and emitting the particles from the target 30. A light measuring device 40 measures plasma emission L2 from the target 30 upon in-focus irradiation with the laser beam L1 and an analyzing device 50 analyzes a measurement signal therefrom to assess a generation state of fast particles P. Then the focusing optical system 20 and target 30 are controlled through optical system moving mechanism 25 and target moving mechanism 35 on the basis of the result of the analysis and feedback control is performed on the generation state of fast particles P in the target 30. This realizes a fast particle generating apparatus capable of monitoring the generation state of fast particles in real time and thereby efficiently generating the fast particles.

摘要： 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.

摘要： The transparent medium processing device comprises: a light control section 2 for performing variable control for the status of the laser beam emitted from the light source section 1, and a light status measurement section 4 for measuring the status of the laser beam inside the processing target TG. The light control section is adjusted based on the output of the light status measurement section so that the status of the laser beam inside the processing target becomes a desired status. Since the status of the laser beam inside the processing target, which is made of such a transparent medium as glass, is measured by the light status measurement section, and is fed back to the light control section, laser processing can be executed while maintaining an optimum status at a processing point inside the processing target.
