摘要:
A detection apparatus for detecting foreign substances or defective goods, with which it is easy to accomplish inspection even if the inspection objects have a shape that tends to allow rolling, comprises: transparent members 11 and 12, partitions 21 and 22, a supplying unit 30, cameras 41 and 42, a control unit 50. A removing apparatus 1, which includes such detection apparatus, comprises a suction controller 60 and suction nozzles 61 to 68. While the partitions 21, 22 move around, inspection objects A are each put in each cell of the partitions 21, 22, and are photographed by the cameras 41 and 42, from above and below the transparent members 11, 12, respectively. The images obtained by such photographing are analyzed, and foreign substances or defective goods mingling in the inspection objects A are detected. The foreign substances or defective goods are separated from the conforming goods by selectively sucking the inspection objects A with the suction nozzles 61 to 64.
摘要:
The present invention relates to a blood vessel wall analyzing apparatus provided with a structure enabling accurate measurement of plaque components in a blood vessel wall in a state that reduces the burden on a patient. In the blood vessel wall analyzing apparatus (1), measurement light is illuminated onto a measured portion within a blood vessel such as a carotid artery (C) from a light illuminating unit (30) provided outside the blood vessel, while light from the measured portion is detected in a light receiving unit (40) provided outside the blood vessel. Thus, since the status of the blood vessel wall can be analyzed without inserting an apparatus involved in measurement into the blood vessel, the burden on the patient is reduced during measurement. In addition, as a result of carrying out measurement using near infrared light (a light component in the wavelength range of 780 nm to 2750 nm) that exhibits characteristics that differ according to the compositions of substances such as plaque adhered within the blood vessel, analyses can be carried out that distinguish compositions such as plaque using an analyzing apparatus provided outside the blood vessel.

The present invention relates to a blood vessel inner wall analyzing apparatus provided with a structure for more accurately analyzing components of substances adhered to the inner walls of blood vessels. A blood vessel inner wall analyzing apparatus (1) is provided with illuminating means, detecting means and analyzing means. The illuminating means illuminates a light component in a measurement wavelength range of 1957 nm to 2713 nm onto a measured position from an end surface (30b) of a light illuminating fiber (30) inserted into a carotid artery (C). The detecting means receives a light component from a measured position through an end surface (40a) of a light receiving fiber (40) within the carotid artery (C). The light component to be detected is a light component in a detection wavelength range which extends 15 nm on both short and long sides of the selected center wavelength, with each one or more center wavelengths being selected from a wavelength group comprised of specific wavelengths respectively in the measurement wavelength range. The analyzing means analyzes for the presence or absence of substances differing from blood by using intensity information on the detected light component.

Provided is a boiler structure with which, by reducing the pressure drop in boiler evaporation tubes correspondingly to the heat flux, which varies in accordance with the distance in the boiler height direction, it is possible to reduce auxiliary power for a water feed pump and so forth, in addition to improving the flow stability and the natural circulation characteristics. The boiler structure includes a number of boiler evaporation tubes that are arranged on a wall surface of a furnace and that form a furnace wall, water pumped into the boiler evaporation tubes being heated in the furnace during flowing inside the tubes to produce steam, wherein the boiler evaporation tubes are formed by connecting tubes of a plurality of types, in which tube wall thicknesses are adjusted on the basis of furnace heat flux such that the higher the furnace heat flux in a region is, the smaller the tube inner diameter becomes.

A database system is provided with a search unit for searching image attribute information that has been stored in a relational database management system. A search interface is provided between the search unit and a command execution unit, which applies a search command to the search unit. The command execution unit and search unit can be connected in detachable fashion. Thus a search unit that has been connected to the command execution unit can be replaced by detaching it and connecting a search unit that employs another search technique.

A hologram recording medium comprises a hologram recording layer for recording a hologram, and a wedge substrate for varying the propagating direction of a reference light and an object light incident upon the hologram recording medium. By rotating the hologram recording medium comprising the hologram recording layer and the wedge substrate, the propagating direction of the reference light and the object light are varied, whereby angle multiplex recording of holograms can be realized with ease.

An optical pick-up apparatus includes a light source, an objective lens, a beam splitter, a detector, a first optical compensating device and a second optical compensating device. The objective lens converges a light beam emitted from the light source at one point on an optical axis. The beam splitter separates the light beam emitted from the light source from a returning light reflected on an optical disc. The detector detects the returning light separated from the light beam emitted from the light source. The first optical compensating device has a convex aspherical surface represented by X.alpha.R.sup.4 and is located on an optical path where the light beam is emitted from the light source. The second optical compensating device has a concave aspherical surface represented by +.alpha.R.sup.4 and is located on an optical path where the light beam is emitted from the light source.
