Abstract: An optical fiber unit enables secure grasping of an optical fiber sensor via a jig while avoiding damage to an optical fiber cable. The optical fiber unit for the optical fiber sensor includes an optical fiber cable, a shaft, and a head. The shaft includes a peripheral surface having a male thread, and a through-hole for an inserted optical fiber cable. The head is shaped in a hexagonal prism including six sides and a bottom. The shaft is connected to the bottom of the head. The optical fiber cable extends the head, and extends out of the head in a direction substantially parallel to two parallel sides of the six sides from at least one of the six sides excluding the two parallel sides.

Abstract: Disclosed is an optical fiber unit that improves the degree of freedom in setting a jig. The unit includes an optical fiber cable, a shaft, and a head. The shaft includes a peripheral surface having a male thread, and a through-hole in which the optical fiber cable is inserted. The head is shaped as a polygonal prism including a plurality of sides and a bottom. The plurality of sides includes a first side and a second side adjacent to each other. The head includes a space that communicates with the through-hole. The space is exposed at an opening formed in at least the first side and the second side among the plurality of sides. The opening includes a first opening portion formed in the first side, and a second opening portion formed in the second side. The first opening portion and the second opening portion communicate with each other.

Abstract: This embodiment provides an optical fiber head in which a lens can reliably be fixed to a case body by a simple configuration, and therefore the optical fiber head can easily be produced at low cost. The optical fiber head includes a light projecting fiber, a light projecting lens, and a case body accommodating and holding the light projecting fiber and the light projecting lens. A blocking unit in which an opening is formed, a light projecting lens inserting hole, and an optical fiber inserting hole are provided in the case body. The light projecting fiber is fixed to the case body while a leading end surface of the light projecting fiber abuts a rear end surface of the light projecting lens, so that the light projecting lens is fixed to the case body by being sandwiched between the blocking unit and the light projecting fiber in an axial direction.

Abstract: According to one embodiment, a mask conveying system includes a stocker, a conveyance path, a storage container, a conveying apparatus, and a control device. The storage container for wafer conveyance has the same structure as the storage container for mask conveyance. The control device determines whether or not the storage container is for mask conveyance when the storage container is introduced into the stocker in an exposure area or the stocker in a mask inspection area, and controls the conveying apparatus such that the storage container is conveyed to the stocker that does not have the storage container introduced when the storage container is for mask conveyance.

Abstract: Light emitted from a light source (22) is used through a light projection optical system (23) to perform coaxial down-emission lighting on a measurement target (36). Light reflected by the measurement target (36) is formed on a photo-detector (26) through an image formation optical system (24). Along its optical path, a spectroscope (25) is provided for converting an image impinging on the photo-detector (26) into a spectroscopic image having a predetermined wavelength band. A measurement point extraction portion (32) in a signal processing portion (28) determines a predeterm film thickness measurement point from an image picked up by the photo-detector (26), extracts an image signal at the film thickness measurement point, and transmits t to film thickness operation portion (33). The film thickness operation portion (33) measured film thickness of a thin film, which is the measurement target (36), from this signal.

Abstract: The measurement light radiated from a radiator 2 enters an object of inspection through an integrating sphere 22. The measurement light is reflected on a base 52 of the object or a thin film 54. Further, the reflected light enters the integrating sphere 22 and is equalized in the integrating sphere 22. After that, the equalized reflected light is led to a light splitter 12 through an optical fiber 10. The light splitter 12 splits the reflected light in the order of wavelength, and applies an electrical signal corresponding to the intensity spectrum to an arithmetic processor 14. The arithmetic processor 14 determines the state of the thin film 54 formed on the surface of the object based on the electrical signal received from the light splitter 12.

Abstract: There is provided an optical card processing apparatus comprising: a card holder which is supported to a guiding mechanism so as to be reciprocated and is formed with an optical card holding portion on a lower surface; a card loading/ejecting mechanism, arranged at a card inserting port, for detecting an optical card and for attaching and detaching the optical card to and from the optical card holding portion of the card holder. A card inclination correcting mechanism is arranged for the card holder, for making a track line direction of the optical card coincide with a moving direction of the card holder. A card transfer mechanism in which a pair of pulleys are arranged along a moving path of the card holder, an endless belt is wound between the pair of pulleys, a proper portion of the belt is coupled with the card holder, and one of the pulleys is coupled with a drive motor which rotates in a single direction.

Abstract: An optical card processing apparatus includes a holder feed mechanism (4) for reciprocating a card holder (2) holding an optical card (8), an optical head (5) for recording information on and/or reproducing information from the optical card held by the card holder, and a card holding mechanism provided on the card holder for pressingly holding at least three sides of the optical card. Deformation of the optical card can be corrected and vibration thereof suppressed by the card holding mechanism. As a result, focal-point error due to card curvature and vibration is reduced and optical cards can be fed at a higher speed.
