Abstract: The nuclear fusion reactor of the present invention presents a new vacuum vessel for enclosing plasma particles where a reactor wall exposed to the above plasma particles has a piled structure. A plurality of heat-resisting ceramic tiles are metallurgically bonded to a metal-base body having a cooling means through a brazing material. The ceramic tiles are preferably composed of sintered silicon carbide of high density and containing a little beryllium oxide between the boundaries of crystal grains.

Abstract: A ceramic substrate with metal plate, wherein a metal plate consisting mainly of copper is bonded to a ceramic substrate through a brazing layer consisting of a mixture of copper oxide and copper.

Abstract: Herein disclosed is a stacked or laminated structure which is rigidly integrated by sandwiching a metal layer between a first matrix-fiber composite layer prepared to have as a whole a thermal expansion coefficient and a second matrix-fiber layer prepared to have as a whole another thermal expansion coefficient different from that of the first matrix-fiber composite layer. The intervening metal layer acts as a buffer for the first and second matrix-fiber composite layers. The stacked structure according to the present invention can by used as the chip carrier of a semiconductor device, for example.

Abstract: A structure for fitting a fuel tank in an automotive vehicle comprises a rear floor panel fixed at a rear portion of the automotive vehicle, a rear seat cross member fixed to the under side of the rear floor panel across the automotive vehicle, a seat belt anchor fixing cross member fixed to the under side of the rear floor panel across the automotive vehicle, and a pair of bands suspended between the rear seat cross member and the seat belt anchor fixing cross member for supporting the fuel tank in position between the rear seat cross member and the seat belt anchor fixing cross member.

Abstract: A non-magnetic metal for integral casting is poured into a mold supporting a couple of magnetic pole pieces with a distance piece placed therebetween. The pole pieces are thus fixed as cast integrally with the mold, and subsequently the distance piece is removed so that there are provided magnetic pole pieces of the type best suited to a nuclear magnetic resonance apparatus, etc.

Abstract: A uniform magnetic field generating device for generating a uniform magnetic field such as that required in a nuclear magnetic resonance device is disclosed. In prior art devices, in order to obtain a highly uniform magnetic field space, a parallel gap has been formed between pole pieces which were magnetically homogenized and mounted on magnets coupled by a yoke. In place of such pole pieces, a magnetically homogenized pole block or a pole block sandwiched by pole pieces is inserted between the magnets and a cylindrical hole or space is formed in the pole block, a sectional area of the space taken in parallel with the direction of a magnetic field due to the magnets and perpendicular to the axial line of the space being of circular, ellipse or rectangular shape, whereby a highly uniform magnetic field space is established.

Abstract: A pole piece for use in a magnet device and a method for manufacturing same, in which the structure of the pole piece for use in a magnet device used in an analyzing apparatus for analyzing such as nuclear magnetic resonance is varied in concentric fashion from the center towards the outer circumference of the pole piece. The pole piece is manufactured according to the die-forging, whereby the magnetic properties of the pole piece become hetrogenous in concentric fashion. The use of such a pole piece brings about a magnet device which is compact in size and which provides a strong and uniform magnetic field.
