| 20090075056 | ALUMINUM-SILICON CARBIDE COMPOSITE BODY AND METHOD FOR PROCESSING THE SAME - An aluminum-silicon carbide composite suitable as e.g. a base plate for power module is provided. | 03-19-2009 |
| 20090092793 | ALUMINUM/SILICON CARBIDE COMPOSITE AND RADIATING PART COMPRISING THE SAME - A base plate for power module, comprising an aluminum-silicon carbide composite and aluminum layers made of a metal containing aluminum as the main component formed on respective principal planes of the aluminum-silicon carbide composite, wherein the aluminum-silicon carbide composite is produced by forming or fabricating a flat plate-shaped silicon carbide porous body to have a thickness difference of at most 100 μm in the entire porous body and piling such porous bodies as they are each sandwiched between mold-releasing plates so that the fastening torque in the plane direction becomes from 1 to 20 Nm, and infiltrating a metal containing aluminum as the main component into the silicon carbide porous bodies, | 04-09-2009 |
| 20090280351 | ALUMINUM/SILICON CARBIDE COMPOSITE AND HEAT RADIATION PART MAKING USE OF THE SAME - An aluminum-silicon carbide composite suitable for a base plate for power module is provided. A base plate for power module, comprising an aluminum-silicon carbide composite that is a flat plate-shaped silicon carbide porous body impregnated with a metal containing aluminum as the main component, and an aluminum layer made of a metal containing aluminum as the main component formed only on one of the principal planes of the composite, wherein a rear surface being the other one of principal planes of the aluminum-silicon carbide composite is exposed to the outside, and the shape of the exposed aluminum-silicon carbide composite is a rectangle or a rectangle from which portions encompassing holes in the peripheral portion are removed. Plating property is imparted to the composite by providing an aluminum layer on one principal plane of the composite, and the flatness of the composite was improved by grinding its rear surface so that the aluminum-silicon carbide composite is exposed to the outside, and further, the warpage shape after the rear surface is ground is controlled by controlling the thickness of the aluminum layer. | 11-12-2009 |

| 20100047573 | SPLITTABLE CONJUGATE FIBER - A splittable conjugate fiber that provides a fiber structure with enhanced compactness, bulkiness and color formation has one member consisting of a polyamide resin composition containing an aromatic polyamide and an aliphatic polyamide and has another member consisting of a fiber forming polymer with no affinity to the polyamide resin composition. Preferably, the aromatic polyamide is a polyamide whose major structural units are composed of an aliphatic dicarboxylic acid and an aromatic diamine. In further preferred modes, the polyamide resin composition consists of nylon-MXD6 and nylon-6, the weight ratio therebetween ranging from 35:65 to 70:30, and the fiber forming polymer is a polyester or polyolefin. | 02-25-2010 |
| 20100112325 | SPLITTABLE CONJUGATE FIBER, FIBER STRUCTURE USING THE SAME AND WIPING CLOTH - A splittable conjugate fiber for obtaining a fiber structure excellent in denseness and bulkiness includes a polyamide resin composition and a fiber-forming polymer not having an affinity with the polyamide resin composition. The polyamide resin composition and the fiber-forming polymer are combined with each other in a fiber longitudinal direction. The polyamide resin composition contains aromatic polyamide and aliphatic polyamide. Preferably, the aromatic polyamide is a nylon MXD6 polymer, and the aliphatic polyamide is a nylon 6 polymer. | 05-06-2010 |
| 20100137527 | HIGHLY SHRINKABLE FIBER - A highly shrinkable fiber composed of nylon-MXD6 polymer and nylon-6 polymer, characterized in that a weight ratio therebetween is in the range of 35:65 to 70:30, and that each thereof exhibits a breaking strength of 4.00 cN/dtex or greater. Preferably, the weight ratio between nylon-MXD6 polymer and nylon-6 polymer of the highly shrinkable fiber is in the range of 45.55 to 55:45. The highly shrinkable fiber exhibits a high shrinkage ratio in boiling water, so that when the highly shrinkable fiber is used in a woven fabric, there can be realized a high density. | 06-03-2010 |
