Abstract: PURPOSE:To reduce the thickness of a protective film and to decrease spacing loss by using oxygen and fluorine-contg. gas as the discharge gas to form the oxide of a Co alloy as the protective film on a thin ferromagnetic metallic film consisting of the Co alloy. CONSTITUTION:The Co alloy oxide of a Co alloy oxide target 20 is vacuum- deposited by a 2nd magnetic field generator 21 on the thin ferromagnetic metallic film 2 on a high-polymer film 1 on which the thin ferromagnetic metallic film 2 consisting of the Co alloy is formed to form the protective film 3 on the thin ferromagnetic metallic film 2 at the time when the above-mentioned high-polymer film 1 is wound on the 2nd rotary support 18 and is moved. The oxygen and fluorine-contg. gas are introduced from a 2nd gas introducing port 11 into a protective film forming chamber 7 so that active fluorine is taken into the surface of the protective film 3. Since the cohesion among the metals is thereby hardly generated even where humidity is low, the thickness of the protective film 3 is reduced and the spacing loss is decreased.

Title: Method for detecting joint position of buried metal pipe with electromagnetic wave, and method for inspecting joint of metal pipe with electromagnetic wave
Inventor: IMAOKA TAKASHI
IPC: G01N22/02
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To detect the joint of a buried metal pipe having a curved part, and shorten the detecting time by exciting an electromagnetic wave to the buried metal pipe with a transmitting device, and propagating it in the metal pipe. SOLUTION: When an electromagnetic wave is supplied from a transmitting device 6 to an exciting part 3 through a coaxial cable 7, the electromagnetic wave of the mode corresponding to the electric field by a probe 5 is excited to propagate the electromagnetic wave through a buried metal pipe 1 in the same mode as a circular waveguide. When the electromagnetic wave is propagated through the metal pipe 1, the electromagnetic wave is leaked to the outside from the position of a joint 2. Thus, the leaked electromagnetic wave is received by a receiving device 9 through an antenna 8, thereby, the joint 2 can be detected.  When the antenna 8 having a high directivity is used in this case, the direction of the antenna 8 is properly changed while moving it along the metal pipe 1 to detect the peak, thereby, the position of the joint 2 can be precisely detected by the direction of the antenna 8 corresponding to the peak.

Abstract: PROBLEM TO BE SOLVED: To provide a portable telephone set whose main body can be removably placed even on a vertical face of a magnetic material or the like, to increase its holding places by providing a magnet on the surface a portable telephone set to removably and freely attach or detach the main body. SOLUTION: A permanent magnet 7 is provided at the bottom side of the back part of a main body 1 and built into the back part (back side of an operation part 5) to be set in parallel to a back face 1b. the magnet 7 has such magnetic force, so that the body 1 is attracted to an object 8 to be attracted and not easily removed by the gravity or the like, but can be easily removed by the human power. Thus, the body 1 is attracted to a vertical face 8a of a magnetic substance 8 such as a metallic pole, etc. The body 1 touches the face 8a via the face 1b of the back side of the part 5 and attracted to the face 8a. Therefore, the keys can be operated at the part 5 even when the body 1 is attracted to the face 8a. Furthermore, the attraction of the magnet 7 is never lost even though the key operation reaction of the part 5 is applied to the part 5.

Title: Sor device
Inventor: BANDAI SHINICHI
IPC: G21K5/02
Filed: 1990-08-13
Abstract: PURPOSE:To deflect and converge an electron beam at the same time in a SOR device for rotating the electron beam at a luminous flux in a synchrotron, so as to extract radiation light, by making the distance of a magnetic pole of a core different in a radius direction of deflection curvature. CONSTITUTION:When an electron beam 12 is moved horizontally from a sheet surface at a deflection part 2a of a vacuum container 2, and when a flux that passes an air gap between magnetic poles 16 and 17, is directed from the lower magnetic pole 17 to the upper magnetic pole 16, as indicated in the figure, a distance d1 on the inside in the radius direction of a deflection curvature is smaller than a distance d0 outside. Since Lorentz's force and inertia force due to the acceleration in the direction of a radius (r) of an electron rotated stably on the central trajectory, are balanced, the electron which is diverted from the central trajectory, receives a force F0 on the inside, or a force F1 on the outside, according to conditions. While an electron beam 12 is deflected at the deflection part 2a, it is also converged. By making the electron beam 12 deflected and converged at the same time at the deflection part 2a, only a little adjustment of the conversion force by quadrupole electromagnet for flattening, is required, and the control thereof is thus facilitated.
