Abstract: An X-ray flux irradiation intensity distribution which is nonuniform due to a heel effect can be made uniform, and a subject can be prevented from being unnecessarily exposed. In addition, image quality of image data obtained with an X-ray CT scanner can be made uniform and improved in a body axis direction. A heel effect compensation filter is configured to have a thickness distribution that uniforms an X-ray intensity angular distribution that is nonuniform in the body axis direction of a subject in an X-ray flux irradiated space. The space is formed by an X-ray flux diverging from an anode in a body width direction of the subject and diverging in a shape of an approximate sector in the body axis direction due to the heel effect, when the X-ray flux generated on the anode by irradiating a thermoelectron beam flux from a cathode to the anode is irradiated on the subject. The thickness distribution can be obtained using a predetermined formula.

Abstract: To comprehensively modify genome, it is intended to develop a transposition system of the copy and paste type which has an improved efficiency. This object has been achieved by the finding that an LTR retrotransposon is partly usable in a transposition system. Namely, a technique of efficiently transferring a foreign gene into a cell by using a transposon. More specifically speaking, a complete IPA element and a functional promoter sequence are found out. It is clarified that, without a combination of them, a retrotransposon cannot exert its function.

Abstract: A microscope apparatus has a sample table for supporting a sample and being mounted to undergo movement in a horizontal direction. A line sensor acquires a line image for each of a series of measuring positions of the sample in accordance with movement of the sample at a constant speed by one measuring width of the line sensor in the horizontal direction. An image processing device produces an image of the sample based on the line images acquired by the line sensor. A focusing device has a light-projecting member for projecting light onto the sample at a position forward of a leading side of an imaging range of the line sensor in the horizontal direction to prevent light reflected by the sample as a result of the projected light from being incident on and interfering with the line images acquired by the line sensor.

Abstract: A method of extracting a strong, charged particle beam, that is, a large current from an accelerator, and an accelerator capable of carrying out the method utilizes charged particles which are extracted from the accelerator. The equilibrium orbit of charged particles in one of a bending magnet and a magnet having multipole components greater than sextuple components, is shifted by a constituent element of the accelerator other than these magnets, to change the tune of charged particles. The adjustment of this tune based upon the shift of the equilibrium orbit in the above magnet for extracting charged particles, can keep the gradient of orbit of the extracted beam substantially constant. Accordingly, beam extraction is readily controlled, and a large current can be extracted from the accelerator.
