Filed: 1988-01-29
Abstract: PURPOSE:To eliminate the undesirable influence of hydrogen on an optical fiber and to decrease the transmission loss of an optical fiber cable by incorporating a hydrogen absorptive metal into the optical fiber cable. CONSTITUTION:A metal which can absorb and occlude hydrogen is incorporated into any of materials except the core and clad materials constituting the optical fiber cable. If, for example, the optical fiber cable has a tension member, metallic tape and metallic sheath, the same metal can be adopted as it is as the tension member and may be twisted in the form of filament together with the optical fiber or may be wound in the form of a tape around the optical fiber cable fiber.

Title: Surface finishing method for article
Inventor: MORIAI CHIKARA
IPC: B24C1/00
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To continuously and efficiently perform surface finishing, prevent solid substance from remaining in fine clearance and hole and prevent a possibility of damaging a surface by processing the surface of an article by cleaning liquid that water soluble compound is added to water soluble compound saturated aqueous solution. SOLUTION: Cleaning liquid 4 is adjusted by further adding and diffusing water soluble compound in water soluble compound saturated aqueous solution that water soluble compound is dissolved in water till water soluble compound is saturated at a using temperature. Even if an article is a complicated shaped one, a surface processing can be efficiently performed only if cleaning liquid 4 is blown. Even if cleaning liquid 4 remains in fine clearance and hole and is dried and water soluble compound remains, water soluble compound can be easily removed by water because the compound is water soluble.  For instance, a workpiece 1 having a groove working surface of 1 mm in width is fixed to a rotatable mounting base 2, cleaning liquid 4 is injected together with compressed air from a nozzle 3, a cleaning burring is performed, a washing is performed by injecting water from a washing nozzle 7, and sticking and remaining cleaning liquid 4 is removed.

Title: Magnet for nuclear magnetic resonance diagnostic tester
Inventor: ONO HARUO
IPC: H01F7/20
Filed: 1986-01-29
Abstract: PURPOSE:To avoid increasing a distance between the magnetic poles to make the magnet smaller in size, lighter in weight and lower in cost, by arranging the gradient magnetic coils so as to enclose the divided annular projections with each of them, using the coil grooves formed likely to quarter the annular projections of the compensating poles along the peripheral direction. CONSTITUTION:For the gradient magnetic field coils 16, 17, 18, 19 formed of fan plate, the cross coil parts 17E are to be inserted into the coil grooves 15 respectively, to as to enclose each fan-form annular projection quartered with the coil grooves 15. The inner coil parts 17D result then in being positioned into the concaves of compensating poles 13A, 13B surrounded by the annular projections, while the outer coil parts 17C along the outer periphery of the annular projections. This results therefore in avoiding the limitation of coil-to-coil distance h required to allow a person to enter the uniform magnetic field 10, thus enabling to completely eliminate an increase in a distance H between the magnetic poles. Further, the partial ununiformity of magnetizing the permanent magnets 2A, 2B can be compensated by the compensating poles 13A, 13B to reduce the magnetic flux leaking toward the outside of the magnetic field space to a level below the annular projections 14A, 14B, thus generating the uniform magnetic field 10 at the center between the pair of magnetic poles.

Title: Protecting circuit of main thyrister
Inventor: IWAHASHI SATORU
IPC: H02H7/08
Filed: 1980-02-14
Abstract: PURPOSE:To prevent the main thyrister from commutation failure and damage by shutting the supply power source when the forward voltage of the main thyrister is risen above a fixed value. CONSTITUTION:When the load current IB flowing in the DC motor 2 exceeds the minimum allowable ''ON'' current of the main thyrister 3, said forward voltage Vs is detected to put out the output signal SG3. As at this time the main thyrister is in the state of ''ON'', the transistor 21 is in the state of ''OFF'', the output signal SG3 is put into the contact making circuit 25 to make the contact 9 to leave off. And when the main thyrister 3 is in the state of ''OFF'', similarly the output signal SG3 is put out, while the output signal SG3 is not put into the contact making circuit because the transistor 21 is turned ''ON'' in the state of ''OFF'' of the main thyristor 3. Thereby when the load current exceeds the maximum allowable ''ON'' current, immediately the power source is cut off to prevent the main thyrister from commutation failure and damage.
