Title: Selected wavelength variable filter
Inventor: ONO TAKEO
IPC: H01S5/00
Filed: 1989-07-19
Abstract: PURPOSE:To allow the tuning for a selected wavelength over a wide wavelength range without generating the loss by absorption by forming a groove for preventing a voltage from being impressed to an optical waveguide region between a distribution feedback region and the optical waveguide region. CONSTITUTION:This filter has electrodes 91, 92 for impressing the voltage to the distribution feedback region and the groove 10 for preventing the voltage from being impressed to the optical waveguide region is formed between the distribution feedback region and the optical waveguide region. The impression of the voltage to the optical waveguide region is prevented by the groove 10 provided between the respective electrodes and only the absorption coefft. of the distribution feedback region changes even when the voltage is impressed to the distribution feedback region in this formation. The loss by the absorption can, therefore, be compensated by selecting the wavelength with which the fluctuation rate of the refractive index on the wavelength side longer than an exciton wavelength is always positive as the selected wavelength. The generation of the loss by the absorption is obviated and the tuning of the selected wavelength over the wide wavelength range is possible.

Filed: 1985-08-22
Abstract: PURPOSE:To contrive improvement in electric resistance of the titled magnetic powder by a method wherein a V2O5-MmOn gel-form oxide is coated or coexisted on the surface of ferromagnetic powder. CONSTITUTION:V2O5-MmOn (M indicates at least a kind of Li, Ti, Mg, Cr, Ba, Zn, Ge, Si and B, and m and n indicate an integral number) oxide is coated or coexisted on the surface of ferromagnetic powder. Said V2O5-MmOn oxide is a gel-form oxide, and it is also formed of amorphous V2O5-MmOn oxide by a very rapid cooling technique using a liquid, copper plate, or the like. As a result, the electric resistance of said material becomes very small, it is hardly electrified, and the variation with time of the magnetic characteristics such as coercive force and the like can be prevented. Accordingly, the noise of discharge, the adhesion of a tape and the like can be prevented, and the excellent magnetic characteristics can be obtained, thereby enabling a high density recording.

Title: Magnetic bubble memory element
Inventor: TAKESHITA MASATOSHI
IPC: G11C11/14
Filed: 1989-07-19
Abstract: PURPOSE:To obtain stable detection output characteristics in a wide stretch pulse phase range by disposing the patterns of soft magnetic materials in such a manner that the patterns intersect with transfer paths for ion implantation and the front ends exist on the side outer than the edges of the transfer paths for ion implantation. CONSTITUTION:The longitudinal front end of a detecting wire 4 consisting of the soft magnetic material is disposed to expand up to the outer region A at the edges of the transfer paths 1 for ion implantation. Since the current of the detecting line does not flow to the soft magnetic pattern of the region A, Joule heat is not generated and, therefore, the magnetic bubble 2 transferred onto the transfer path 1 for ion implantation under the region A does not re ceive the influence of the repulsive magnetic pole generated at the front end of the detecting line 4. Since there is no generation of the Joule heat in the region A and since there is consequently no averse influence on the working bias magnetic characteristics, the detection output characteristics stable in the wide stretch pulse phase range are obtd. There is no influence on the work ing bias magnetic field characteristics either.
