Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a gain equalizer which can equalize the gain-wavelength characteristic of an optical amplifier over a wide wavelength region, and an optical amplifier, and an optical transmission system using the equalizer and amplifier. SOLUTION: A gain equalizer and an optical amplifier are used for a means, which equalizes such an optical filter that has the maximum loss value in a prescribed wavelength region, and asymmetric loss-wavelength characteristic with respect to the wavelength which gives the maximum loss value and makes the wavelength which gives maximum loss value of the optical filter nearly coincidet with the wavelength, which gives the maximum value of the intensity- wavelength characteristic of the light made incident to the optical filter. An optical transmission system having a wide signal transmitting region is built by using such a gain equalizer or optical amplifier.

Title: Production of titanium-containing steel
Inventor: TAKAHASHI HIROSHI
IPC: C21C7/00
Filed: 1994-07-18
Abstract: PURPOSE:To improve the titanium yield of a titanium-containing steel and the precision of titanium concentration regulation. CONSTITUTION:A molten stainless steel 9 is poured into a ladle 10 and held in a vessel 2. A vessel cover 3 is airtightly put on the vessel 2, and the inside space 13 is sucked and evacuated by an evacuation means 4. Argon gas is blown into the molten steel 9 through porous plugs 12 in the bottom of the ladle 10 and agitates the molten steel 9. Oxygen gas is blown through an oxygen blowing lance 6 against the surface of the molten steel 9. The molten steel is decarburized by oxygen blowing under agitation under reduced pressure and then deoxidized by aluminum thrown from an alloy adding device 8. Aluminum deoxidation time is determined on the basis of the uniform mixing time of the molten steel and is longer than that by the conventional method. After aluminum deoxidation, titanium is thrown into the molten steel. When titanium concentration is lower than the desired value, the additional throwing of titanium is done, thereby, the titanium-containing stainless steel can be refined. The amount of additionally thrown titanium is determined by the logical method.

Title: Erasable thermal recording method
Inventor: YAMAMURA MASATO
IPC: G11B7/0055
Filed: 1988-07-04
Abstract: PURPOSE:To erase recording information by heating and annealing by an information recording method wherein a heat above an isotropic phase transition temperature is pulsatively applied on a recording medium having a polymeric liquid crystal material through a thermal recording means and, thereafter, the medium is quenched. CONSTITUTION:A pulse current from an information source is applied to a resistor 8 of a recording head 6 which is relatively running in contact with a recording medium 1, whereby the polymeric liquid crystal of a recording layer 4 is momentarily heated above a clearing point. The phase of the recording layer turns from a liquid crystal glass phase to an isotropic phase through a liquid crystal phase. After being quenched by turning OFF the current, it transits from the isotropic phase to an isotropic amorphous phase through an unstable isotropic phase. Then, a recording material is made transparent and identifiable with a high-reflective aluminum vapor-deposited film 3 exposed. The recording layer 4 is heated by a resistor 9 of an erasing head 7 and annealed, thereby returning to an opaque liquid crystal glass phase and erasing the recording thereon.

In addition, the aspect ratio thereof is preferably 10 or more. As a result, low partial density can be formed, depending upon the percentage of void between each of the base fiber. Also, fine carbon particles can be arrested with the calcium carbonate in whisker state. When this example of product is compared with a conventional product having base fiber blended with the same amount of calcium carbonate, the arrest rates of carbon particles are respectively 30wt.% and 25wt.%.
