A radiotherapy device control apparatus controls a radiotherapy device. The control apparatus includes a reference image creation section, a transmitted image creation section and an affected area position control section. The radiotherapy device includes a therapeutic radiation irradiation device that radiates therapeutic radiation, an imager that generates an image of a subject by using radiation transmitted through the subject, and a drive device that moves a couch, where the subject is arranged, with respect to the therapeutic radiation irradiation device. The affected area position control section judges whether a relative position of the couch with respect to the therapeutic radiation irradiation device is appropriate and changes the relative position of the couch by using the drive device based on a first position and a second position.

Radiotherapy device control apparatus and radiation irradiation method

A radiotherapy device control apparatus includes: a template matching section; an affected area position calculating section; and an irradiation position control section. The radiotherapy device control apparatus controls a radiotherapy device. The radiotherapy device includes: a therapeutic radiation irradiation device radiating therapeutic radiation, and an imager generating an imager image of a subject by using radiation transmitted through the subject. The template matching section calculates degree of coincidence when a pattern matching is executed on the imager image with a plurality of image templates in which positional relations between an object area and a non-object area of the subject are different, and selects a specified image template having the degree of coincidence within a predetermined range from the plurality of image templates. The affected area position calculating section calculates a position of the object area by using the specified image template. The irradiation position control section judges whether a relative position of the object area with respect to the therapeutic radiation irradiation device. The irradiation position control section moves one of the therapeutic radiation irradiation device and a couch with the subject by using a drive device provided with the radiotherapy device such that the object area is irradiated with the therapeutic radiation.

An apparatus for recognizing a position, a diameter and a width of a cylindrical object such as a coil made of thin steel plate being wound while observed by a TV camera in unmanned manner. The coil is irradiated with laser light while the laser light is moved in the direction perpendicular to an axial direction of the coil. An image data by the laser light is obtained from a difference of image data in the case where the coil is irradiated with the laser light and in the case where the coil is not irradiated with the laser light. The image data is analyzed to obtain data such as the position and the like. In order to improve an S/N ratio of the image data, the difference signal is binarized and then integrated for a frame. Influence of the background light can be minimized and a memory capacity for the image data can be reduced.

A continuous casting device includes a pair of cooling rolls (1, 2) that rotate in opposite directions to each other. A pair of side weirs (11) have inner surfaces (11a) that covers the end surfaces (1a, 2a) of the cooling rolls (1, 2) and circular surfaces (12b) that covers the peripheral surfaces (1b, 2b) of the cooling rolls (1, 2). At least one of the side weirs (11) is movable in an axial direction of the cooling rolls (1, 2). The continuous casting device also includes electromagnets for forming a magnetic flux in a direction parallel with a contact surface of the side weirs (11) with the molten metal (4) the contact surface extending along the peripheral surfaces (1b, 2b) of the cooling rolls (1, 2) at the portions opposite to the peripheral surfaces (1b, 2b) of the cooling rolls (1, 2) of the side weirs (11).

An alternating current magnetic levitation transport system transporting a floating body made of conductive paramagnetic or nonmagnetic metallic material being levitated over alternating current electromagnets by making use of repulsion of an alternating electromagnetic field, comprises a tubular passage provided over the alternating current electromagnets which are spatially cut off from the outside wherein the floating body is levitated and transported. A cooling system made of a conjoined body of a thermoelectric cooling thermomodule and a liquid-cooled heat exchanger is provided in the transport system in contact with said tubular passage. This system can be favorably used in a clean environment where dust generation has to be avoided and the system can thereby provide more efficient transportation.

Alternating current magnetic levitation transport system

The present invention relates to a magnetic levitating transport system for transporting a levitating body composed of conductive paramagnetic or non-magnetic metal above electromagnet arrays by generating an alternating magnetic field in a pair of parallel electromagnet arrays. The dimensions of the levitating body are expressed in relation to dimensions of the electromagnet arrays, as well as, other dimensions of the levitating body. The specific symmetrical shape, having a flat underside, allows the levitating body to manoeuvre a curve having a large curvature. In addition, perpendicular direction changes are effected using transportation passages.

This invention provides a drawing machine for pinching and stretching a film-like material of the type having rails installed extending from an inlet section to the outlet section and returning in the opposite direction from the outlet section back to the inlet section of the drawing machine. There is a clip propelling unit moving on the rails for pinching and stretching the film-like material, and elements for generating mutually repelling magnetic fields between the rails and clips, whereby the clips are movable in the non-contact state while floating from the rail guide surfaces. Thus, no foreign substances are generated, cleanliness of products is enhanced, no noise is generated, the work environment is improved, energy is saved, and highspeed operation is attained.
