摘要:
A sample analysis method is provided for analyzing a sample having a permeability to terahertz radiation and accurately measure the composition, physical properties, mass and dimensions of a very small sample or a minute amount of sample by irradiating the sample with terahertz radiation. In the method, a reflective member is provided adjoining a first principal surface of the sample, an entrance member is provided adjoining a second principal surface of the sample, terahertz radiation is delivered from outside of entrance member towards the sample, and the sample is analyzed using an interference wave generated from a first-surface reflected wave at the interface between the first principal surface of the sample and the reflective member and a second-surface reflected wave at the interface between the second principal surface of the sample and the entrance member.

In order to generate a two-dimensional image of a sample in a short time using THz waves, provided is a reflective imaging device including a sample holder, a THz wave light source, a THz wave camera, a rotation mechanism for rotating the holder and the camera, and a processing unit. A sample unit includes an incidence member, a sample, and a reflection member. The sample includes a first region of only a membrane and a second region including a biopolymer. The camera detects, with regard to respective incident angles, a THz wave in which interference occurs between a component reflected at an interface between the incidence member and the sample and a component reflected at an interface between the sample and the reflection member, of each portion of the sample unit, and outputs a signal. The processing unit specifies an incident angle at which a signal of a first THz wave that interferes in the first region is relatively small and a signal of a second THz that interferes in the second region is relatively large, and generates a two-dimensional image of the sample based on the signal from the camera with regard to the specified incident angle.

A method of attaching an object to be measured to a structure causing a diffraction phenomenon; irradiating the structure to which the object to be measured is attached and which causes the diffraction phenomenon with an electromagnetic wave; detecting the electromagnetic wave scattered by the structure causing the diffraction phenomenon; and measuring a characteristic of the object to be measured from the frequency characteristic of the detected electromagnetic wave. The object to be measured is attached directly to the surface of the structure causing the diffraction phenomenon. Thus, the method for measuring the characteristic of an object to be measured exhibits an improved measurement sensitivity and high reproducibility. A structure causing a diffraction phenomenon and used for the method, and a measuring device are provided.

There is provided a measuring apparatus including a space arrangement structure that includes space regions surrounded by conductors in a plane, an electromagnetic wave emitter that emits electromagnetic waves towards an object held by the space arrangement structure, and an electromagnetic wave detector that measures the electromagnetic waves that have passed through the space arrangement structure. Here, characteristics of the object are measured by measuring the electromagnetic waves that have passed through the space arrangement structure. The electromagnetic waves emitted from the electromagnetic wave emitter towards the space arrangement structure are incident on the plane containing the space regions at an angle, and the electromagnetic waves that have passed through the space arrangement structure are measured.

An image forming apparatus executes banding correction at a level determined according to variation of the density characteristic of the image forming apparatus to achieve a high quality image. In the image forming apparatus, a banding correction unit acquires information about a cause of density variation that may occur in a sub scanning direction of a rotation member, which is used for forming a toner image on an image carrier based on input image information and sets, based on the acquired information, the level of the density correction, which is determined according to the density variation cause information.

A pellet 4 for use in spectrometry includes a first powder 41 of a light transmitting material in a compression-molded form, and a second powder 42 which is hydrophilic and water-insoluble and is dispersedly mixed in the first powder. A sample 40 to be subjected to spectrometry is e.g. in a powdery form and dispersedly mixed in the first and the second powders 41 and 42. When the sample 40 is a hydrate, the second powder 42 exerts the effect of accelerating dehydration of the sample 40, so that stable spectrum data on the sample in the dehydrated state is obtained early. This makes it possible to perform a processing such as identification of the sample 40 early and precisely.

In registering operation of a document to be searched for, a document identifier management table for managing a range of a document identifier stored for each page and a page identifier of the page is created, and an individual-search-server's search range management table for managing the range of the document identifier in charge of each search server is created. In searching operation of each search server of the document to be searched for, the individual-search-server's search range management table is referred to acquire a range of the allocated document identifier. For each index key forming a query term specified as a query condition, the document identifier management table is referred to to acquire the page identifier storing the document identifier of the allocated range. The searching operation is carried out by referring to a page shown by the acquired page identifier.
摘要:
This invention provides an amorphous transformer for electric power supply, using a magnetic core formed of an amorphous alloy material, which, as compared with the conventional amorphous alloy material, has a lower annealing temperature and a higher level of magnetic properties. The amorphous transformer for electric power supply is provided with a magnetic core of a thin band of an amorphous alloy and a winding wire. The iron core has been annealed under such conditions that the iron core center part temperature during annealing after iron core molding is 300 to 340° C. and the holding time is not less than 0.5 hr. Further, for the iron core, the magnetic field intensity during annealing after the iron core molding is not less than 800 A/m.
