Title: Magnetic flaw detector for rope
Inventor: SATOU YOSHIHIKO
IPC: G01N27/83
Filed: 1979-06-29
Abstract: PURPOSE: To eliminate the need for a magnetic shielding plate for the coil mold of the detection coil in a magnetic flaw detector by forming the coil mold of conductive nonmagnetic material, which is grounded.  
     CONSTITUTION: A traveling rope 1 under test is passed through holes of a pair of pole pieces 4a and 4b of an exciter 2, and a given section of the rope is magnetized by the electromagnetic force of an exciter body 3 comprising an electromagnetic coil. The power for the exciter body 3 is supplied from a power source 5 comprising a transformer 5a, rectifier 5b, smoothing circuit 5c, or the like. Thus, if the rope 1 has such damage as broken wires, the magnetic flux in the rope 1 is disordered, so that a leakage flux is produced on the surface. Consequently, a minute voltage is induced in a detection coil 6, and recorded as a damage signal on a recorder 8. Since a coil mold 9 wound around the detection coil 6 is formed of a conductive nonmagnetic material and grounded, external noises, which are allowed to escape, substantially have no effect on the detection coil 6.

Title: Illumination light source
Inventor: TAKAYAMA AKIRA
IPC: H01J63/06
Filed: 1990-03-30
Abstract: PURPOSE:To obtain an illumination light source of flat type whose unevenness of luminance is small by using as an emission source a micro cold cathode tube having an emitter for field emission and a collector both arranged in a plane, and causing the emission source to emit light from a plane as a whole. CONSTITUTION:An electron emitter 12, an electron collector electrode 15 and a thin film 16 of light-emitting material, etc., are formed on respective portions of a base 11. An electron beam emitted from the electron emitter 12 is urged to collide with the electron collector electrode 15 with energy corresponding to the potential difference between the emitter 12 and the electron collector electrode 15 and thereby the thin film 16 of light-emitting material on the collector electrode 15 is excited to emit light and the light is emitted to the outside through a transparent sealing body 18. Because the thin film 16 of light-emitting material is formed over roughly the whole surface of the base 11, light emission as from a plane is possible and the thin film 16 acts as a planar light source. An illumination light source of flat type whose unevenness of luminance is small is thus obtained.

Title: Retaining device for internal receptacle gyro device
Inventor: MINOHARA KIYOMI
IPC: G01C19/38
Filed: 1980-06-16
Abstract: PURPOSE:To enable to hold an inner ball in a steady manner, by a method wherein a lower part of the inner ball is supported with mainly a conductive liquid having a large specific gravity, and an upper part is supported by means of magnets. CONSTITUTION:An external ball 1, secured on a ship hull by means of a gimbal mechanism, is filled with a magnetic fluid 2, and an internal receptacle 3, housing a high-speed spinning top, is housed therein. Permanent magnets 4 are located in the outer shell of the external ball 1 and in positions corresponding to tops of a regular polyhedron which contacts the inner surface of the external ball. The specific gravity of the internal ball 3 is slightly larger than that of the magnetic fluid 2. Additionally, a proper amount of mercury 5 is poured into the external ball 1. The concentration of the magnetic fluid 2 increases the further close to the external ball 1 the internal ball 3 comes, and as a result, a buffer action prevents the internal ball 3 from making contact with the external ball 1. Even when a specific gravity becomes low resulting from the rise in the temperature of the fluid 2, the bottom part  of the internal ball is supported by a mercury bed. This enables a stable holding of the internal ball 3.
