Title: Heat treatment of fe-al soft magnetic material and jig used therefor
Inventor: KUGA NORIYOSHI
IPC: H01F1/14
Filed: 1993-10-19
Abstract: PURPOSE:To form a strong corrosion resisting film on a surface without deteriorating the magnetic properties of an Fe-Al soft magnetic material, as a material to be treated, at the time of magnetic annealing. CONSTITUTION:Plural materials 1 to be treated, composed of Fe-1%Al soft magnetic materials, are heated and held in a reducing atmosphere at 950-1150 deg.C for prescribed time and cooled slowly, together with a heat treatment jig 2 constituted of a sintered compact of A;2O3. The arrangement jig 2 is constituted of a supporting body 3 for arranging the materials to be treated into laminated state and supporting them, a base 4 for holding the supporting bodies, and a cover 5. Al constituting the jig is allowed to diffuse into the surface layer part of the materials to be treated, where an oxide film composed essentially of Al is formed. The amount of diffusion of Al is increased in the part requiring the utmost corrosion resistance by bringing the supporting body into contact, by which concentration and film thickness are increased. Because the corrosion resisting film composed essentially of Al is formed by using Al component in the jig as well as Al component in the materials to be treated, the decrease in Al component in the materials to be treated can be controlled and electromagnetic parts free from deterioration in magnetic properties can be mass-produced.

Title: Acoustooptic switch
Inventor: ISHIKAWA AKIRA
IPC: G02F1/33
Filed: 1986-10-31
Abstract: PURPOSE:To reduce polarization dependency by using a polarization plane maintaining fiber as the 1st optical fiber and providing a 1/4-wavelength plate. CONSTITUTION:The 1/4-wavelength plate 90 is provided on the optical axis between an acoustooptic element 50 using As2Se3 and a convergent rod lens 42 so that a linear polarized light beam emitted from the polarization plane maintaining fiber becomes a circular polarized light beam. A single mode fiber 20, therefore, emits circular polarized light. When this acoustooptic switch is used for a pulse tester, back scattered light from a fiber to be measured also becomes nearly circular polarized light, which passes through the 1/4-wavelength plate 90 again and is incident on the element 50 as a linear polarized light beam, so waveform fluctuations due to polarization characteristics are reducible. Thus, the circular polarized light passes through the acoustooptic element, so linear polarized beams having all angles of polarization can be present on an average, so the polarization dependency can be reduced.

Title: Light amplifier and amplifying method
Inventor: KEBIN KURISUTOFUAA BAIRON
IPC: H01S3/30
Filed: 1984-12-11
Abstract: @ Use is made of stimulated Raman emission to induce gain in an optical signal (13) of a first wavelength. The optical signal (13) and a pump signal (14) are synchronously coupled to a length of optical fibre (15). The pump signal is at a second wavelength. The first wavelength corresponds to one Stokes shift from the pump signal. The pump signal is generated by a semiconductor laser (11) and thus only relatively low pump powers are involved in comparison with the conventional use of YAG lasers as the pumps, however significant gain is achieved despite the low pump powers. Preferably the optical fibre (15) has a high Raman cross-section and a low transmission loss, for example GeO<sub>2</sub> doped SiO<sub>2</sub> or pure Ge0<sub>2</sub>.

Title: Vibration damping device for structure
Inventor: UTSUNO HIDEO
IPC: E04H9/02
Filed: 1990-09-28
Abstract: PURPOSE:To extend a working temperature range for a vibration damping device by setting the thickness of a viscoelastic body so that dissipation factor of the viscoelastic body at a prescribed temperature can fall within a prescribed range. CONSTITUTION:In a vibration damping device 1a, the thickness is set as 1mm so that the value of dissipation factor of a viscoelastic body 7a such as, for example, vinyl acetate-related resin at a prescribed temperature 5 deg.C can fall within a prescribed range. Thereby, even if the temperature of a structure 2 such as a floor panel becomes about 5 deg.C in the winter time, vibration of the structure 2 can be restricted sufficiently. By the way, when the temperature of the viscoelastic body 7a is high in the summer time and so on, the dissipation factor of the viscoelastic body 7a goes beyond its tolerance, so that a vibration damping device 1 equipped with a viscoelastic body 7, in which a prescribed temperature is set as 20 deg.C and the thickness is set as 50mum, is installed in the structure 2 in addition to the vibration damping device 1a. Thereby, in the summer time or in the intermediate period, the vibration damping device 1 can restrict the vibration of the structure 2, and in the winter time and so on, the vibration damping device 1a can restrict the vibration.
