Plural camera heads are each placed in a position capable of detection of radiation emitted from a radiation source. Compton cones obtained from the detection data output from each of the plural camera heads are projected onto three-dimensional space and an image based on the radiation source is reconstructed. In addition, projected images from projecting Compton cones obtained from the detection data output from each camera head onto two-dimensional planes are also employed for determining a three-dimensional space excluding regions where the radiation source is not present. Reconstruction of images based on the radiation source is then performed within the determined three-dimensional space.
摘要:
A method and a device for directly molding a glazing gasket by extruding a molding material from a molding die to a peripheral edge part of a double-glazing panel in which a space layer is formed between two adjacent glass sheets with a spacer interposed in between. The molding die is configured of a front die and a rear die, which are independent of each other. The front die is allowed to adhere closely to at least the front surface of the double-glazing panel, and the rear die is allowed to adhere closely to at least the rear surface of the double-glazing panel, thereby molding the glazing gasket.

摘要:
This invention relates to the high tension voltage source using a blocking oscillation circuit, wherein a switching transistor is cut off at a certain preset current value through a primary winding of a step-up transformer, thereby producing an output of almost constant voltage by use of this simple circuit, while reducing power consumption. This invention is applicable as a D.C. high tension voltage source for electrostatic dust collectors, namely cottrells.

A subject is imaged for treatment of the subject such as an eye to be inspected, while irradiating a charged particle beam on the eye, so that an aim position of a charged particle beam for treatment can be determined.The device for determining an aim position of a charged particle beam includes a range adjuster 14 that adjusts an irradiation position, in a depth direction of the eye, of a charged particle beam irradiated from a charged particle beam source, a mirror 18 that transmits or passes the position determining charged particle beam and reflects an emitted light emitted from a region of the eye on which the charged particle beam is irradiated and an emitted light emitted, due to an irradiated of an excitation light, from a region including the region of the eye on which the position determining charged particle beam, toward the outside of the axis of the charged particle beam, and an eyeground imaging device 24 that is arranged at a position where the emitted lights reflected from the mirror are incident and images the region including the region of the eye on which the charged particle beam is irradiated by causing the emitted lights to be incident, so that it allows to determine an aim position of a charged particle beam for treatment based on a imaged image.
摘要:
A positive ion of an isomer is generated in an ion source and introduced into a target chamber filled with a target alkali metal so that it is dissociated into a neutral fragment which is then subjected to charge inversion to generate a negative ion. By measuring the mass spectrum of the negative ion, the isomer can be detected at a higher resolution than has been possible by CID and other conventional mass spectroscopic techniques.
摘要:
A radiation-resistant grease that is stable under elevated temperatures is disclosed. The grease is prepared by mixing a bentonite-based thickening agent with a base oil composed of m-(m-phenoxyphenoxy)diphenyl, pentaphenyl ether, a monoalkyltriphenyl ether or a monoalkyltetraphenyl ether (provided that the alkyl group contains 6-20 carbon atoms). To the mixture is added, if necessary, a gelling aid composed of an aliphatic alcohol, an aliphatic ketone and/or an aliphatic carbonate ester.
