Abstract: It is an object of the present invention to improve visibility for observation with naked eyes or for camera shooting without spoiling the appearance during marking inside a transparent medium using a laser. By irradiating an inside of a transparent medium with a laser, the present invention forms a micro-denatured region in each of a first layer and a second layer inside the medium. The micro-denatured regions in the respective layers are arranged out of alignment with each other on a two-dimensional plane (refer to FIG. 1).

Abstract: An image forming apparatus includes a conveying unit to convey a recording medium, a sheet discharge unit provided inside the apparatus body to receive the recording medium, a cover that opens and closes to allow access to the conveying unit, an operation unit to operate the image forming apparatus, a support unit to slidably support the operation unit, and an urging member. The urging member urges the operation unit towards a movement destination when the operation unit is slid.

Abstract: In multiplex CARS, a fingerprint region is a region where signals are densely concentrated. Information about the intensities and spatial distribution of these signals is important in cell analysis. However, there has been a problem in that the signal intensities are low. Accordingly, mechanisms 702 and 703 for adjusting the power branching ratio between light that enters a photonic crystal fiber 705 and pumping light; mechanisms 710 and 711 for adjusting the divergence/convergence state of the pumping light; and mechanisms 706 and 2101 for adjusting the divergence/convergence state of Stokes light are provided to enable adjustment for emphasizing a desired wavelength band.

Abstract: It is made possible to amplify signal light of an optical fiber sensor and to perform measurement in a long distance. At least one of a plurality of core wires in a multicore optical fiber is used as a signal-light propagating core wire 133 and the other is used as a reference-light propagating core wire 134. Also, homodyne detection of signal light and reference light reflected by an FBG sensor unit 132 arranged in each measurement point is performed. Thus, signal light is amplified. In order to make a difference between optical path lengths of the signal light and the reference light equal to or smaller than a coherence length, an optical path-length adjustment unit including a piezoelectric element or the like is arranged in an optical path of the reference light.

Abstract: A vacuum cleaner capable of more efficiently cleaning narrow spots while effectively avoiding an object. An object sensor provided in a main casing detects the presence or absence of an object within a specified distance in a plurality of directions on a forward side of the main casing. A control unit controls operation of driving wheels, based on detection of an object by the object sensor to thereby make the main casing autonomously travel. When an object is detected by the object sensor, the control unit controls the operation of the driving wheels, so that the main casing is swung to an angle corresponding to a direction of the detected object to thereby make a side portion of the main casing face the object.

Abstract: In recording technologies for batch formation of a plurality of recording bits in a recording medium by forming a plurality of optical spots using an ultrashort pulse laser and a spatial optical modulator, the batch recordable bit number has an upper limit, resulting in restricted recording speed. The intensity of the optical spot is corrected to increase the batch recordable bit number for increasing the recording speed.

Abstract: An inventory management system includes an image capturing device, a data storage, and a processing device. The processing device is configured to process image data of one or more images of an inventory space for items of a same type captured by the image capturing device, and to extract, from the captured images, an identification code that is unique to the items and placed behind the inventory space when viewed from the image capturing device. When the processing device is able to extract the entire identification code, the processing device causes an update of an inventory record stored in the data storage to indicate that the items are out of stock if the inventory record for the items are present.

Abstract: In a first mode, a control unit controls operation of driving wheels so that a main casing is made to travel straight and, upon detection of an object by an object sensor, the main casing is changed in traveling direction and made to travel straight. In a second mode, the control unit controls the operation of the driving wheels so that the main casing travels in a curved shape along an object detected by the object sensor. When a charging device is not found by a signal reception part during traveling within a region by the first mode, the control unit is changed over to the second mode. The control unit is changed over to the first mode when it is decided a specified number of times or more that the main casing has moved to a different region by the second mode.

Abstract: Provided is a compact, low-cost optical measuring apparatus capable of acquiring an image of a target to be measured without moving a mirror or using a wavelength-scanning light source or beam splitter. A laser beam emitted from a light source is split into first and second beams, and the first beam is focused as a signal beam onto the target by a lens for irradiation purposes, while the second beam is reflected as a reference beam by a mirror without irradiating the target. Then, a signal beam reflected by or scattered by the target is multiplexed with the reference beam and then enters interference optics, whereby three or more interference beams with different phases are generated and detected by photodetectors. Then, the detection signals are operated by a signal processing unit. During the measurement, the focus position of the first beam is moved at least in the optical axis direction.

Abstract: When recording is performed by focusing a short pulse laser on an inside of a transparent medium such as quartz glass, and forming a minute deformed region in which the refractive index is different from that of surroundings thereof, it is difficult to ensure a recording quality. Therefore, a recorded dot length in a depth direction is monitored 111 and a power of the laser light is adjusted based on the monitored recorded dot length, or a difference between a focus position where a region of the recorded dots appears brighter than the surroundings and a focus position where the region of the recorded dots appears darker than the surroundings is measured and the power of the laser light is adjusted based on the difference.

Abstract: To measure a surface state, reflective CARS is suitable in terms of the signal intensity. However, with the reflective CARS, it has been difficult to identify the surface position because the shape information is not acquired. Thus, a reflective CARS microscope is combined with a high-resolution phase sensor. The surface position is identified with the phase sensor, and reflected CARS generated from the surface is detected, so that composition analysis is performed.

Abstract: When a simple magnification optical system is used in reproduction of a recording medium in which a large number of minute modified regions are three-dimensionally formed inside solid matter, contrast is insufficient and interlayer crosstalk is increased, and therefore, it is impossible to take a sufficient S/N ratio. Provided is a recording medium in which at least one layer is configured by a set of two adjacent sub-layers, and dots on a sub-layer correspond to a recording data ‘1’ and dots on the other sub-layer correspond to ‘0’. These data are played back.
