摘要： PURPOSE:To grow crystal of a specific composition around the surface of a flat plate with arranged crystal axes, by thermally treating a glass component on the flat plate consisting of BaO, SrO, TiO2 and SiO2, through the provision of temperature gradient vertically to the plate surface. CONSTITUTION:BaO, SrO, TiO2 and SiO2 are weighed to obtain the composition indicated by formula (Ba1.0, Sr1.0)TiSi2O8 and mixed with the wet process. After the mixture is dried, it is ground and formed under pressure. A sintered body obtained by sintering it is subjected to high frequency heating, and the molten substance is rapidly cooled to obtain a transparent glassy lump. The lump is cut into a flat plate and one side is optically polished. This flat plate is arranged on the plate surface with a temperature gradient and subjected to heat treatment. Thus, piezoelectric crystal expressed by (Ba2-xSrx)TiSi2O8 (0

摘要： PROBLEM TO BE SOLVED: To perform a precise treatment by detecting an organism situation of a treating object, and arithmetically operating/displaying a treating plan on the basis of the result. SOLUTION: A state of a lesion and a patient is measured by a measuring means 101 to be inputted to a treating plan means 104. A treating plan operation means 106 of the treating plan means 104 arithmetically operates/calculates a treating plan on the basis of this patient state. A treating plan control part 105 sends a control command to an operating means 103 on the basis of the calculated treating plan. Information on the treating plan and information from the measuring means 101 are worked/processed to be displayed on a display means 102. Information from the measuring means 101 and preacquired information on the patient and the lesion are stored in a database 107. Information on this treating plan is sent to the treating plan control means 105. This constitution can perform a precise treatment.

摘要： PURPOSE:To locally decrease gradient magnetic fields generated by a first gradient magnetic field coil by forming this first gradient magnetic field coil as a coil fixed to a magnet and constituting a second gradient magnetic field coil so as to nearly negate the gradient magnetic fields generated by the first gradient magnetic field coil in the specific region of an object to be inspected. CONSTITUTION:The output of the high-frequency pulse generator of an MRI apparatus is amplified by a high-frequency power amplifier to excite the coil 4. The signal received by the coil 4 is subjected to A/D conversion by an A/D converter and is then converted to an image by a signal processing system. This image is displayed by a display device. The small-sized gradient magnetic field coil 22 driven by a current amplifier 23 is installed in addition to the large-sized gradient magnetic field coil 21. The gradient magnetic field coil 22 is so operated as to negate the magnetic field generated by the gradient magnetic field coil 21 only in the specific section of the object to be inspected. As a result, the gradient magnetic fields exclusive of the photographing section are decreased and the uncomfortable feel acting on the object to be inspected is lowered. Photographing is thus executed with excellent safety.

摘要： PURPOSE:To provide an inspection apparatus wherein magnetic resonance in which vortex electric current generated with change of inclined magnetic field is decreased with time is used. CONSTITUTION:A bobbin of a main inclined magnetic field coil 21 and a bobbin of a correction inclined magnetic field coil 23 fixed on a magnet 11 for generating static magnetic field are completely separated each other and the main inclined magnetic field coil 21 is movable in the direction (z) of the static magnetic field. The strength of the inclined magnetic field per unit electric current generated at the center by each of both inclined magnetic fields 21 and 23 differs largely from each other and, as the result, the inclined magnetic field substantially generated as a difference of both cases and the electric current-magnetic field inversion efficiency becomes high. As only the main inclined magnetic field coil 21 is moved, the supporting structure can be made to be light-weight. As the amt. of correction for the vortex electric current, as it is proportional to the strength and the ratio of change with time of the magnetic field generated by the main inclined magnetic field 21, the centers of both inclined magnetic fields can be made to coincide with each other and the effect of the correction can be made smooth in the inspecting space. As the result, high image quality is obtd. in ultrahigh speed photographing.
