|20160001362||FLAKE-LIKE FINE PARTICLES - [Object] To provide fine particles||01-07-2016|
|20150368859||STEEL CORD AND ELASTIC CRAWLER USING SAME - A steel cord is configured so that, when the steel cord is used as a tensile cord for an elastic crawler, a center-core dislocation and the early breakage of the wires of a core are prevented. A steel cord comprises: a core which comprises a single core strand, and a sheath which is formed by twisting together six sheath strands arranged around the core. The core strand has a layer-twisted structure comprising: a center-core portion which is formed by twisting three core wires together; and an external layer portion which is formed by twisting together eight to nine core wires arranged around the center-core portion. The sheath strands each have either a bundle twisted structure which is formed by twisting twelve to nineteen sheath wires or a multi-layer twisted structure which is formed by twisting twelve to nineteen sheath wires in layers. The diameter (dc) of the core wires is greater than the diameter (ds) of the sheath wi res. The average gap (Gc) between the core wi res of the external layer portion is 0.015 mm or greater, and the average gap (Gs) between the sheath strands is 0.1 mm or greater.||12-24-2015|
|20150048196||TRAVERSE DEVICE AND TRAVERSE METHOD - The invention makes it possible to perform regular winding of a wire material by a simple means easily and inexpensively. A guide roller||02-19-2015|
|20130324795||THREE-DIMENSIONAL RETRACTOR - A retractor including an excluding portion having an obtuse distal end, an introduction portion extending from the excluding portion, and a handle portion provided at a proximal end of the introduction portion. The excluding portion and the introduction portion each have an outer diameter that allows insertion into a treatment instrument channel of an endoscope. The excluding portion is configured by a movable wire and a plurality of fixed wires, the movable wire extends through the introduction portion, proximal ends of the fixed wires are fixed to a distal end of the introduction portion, and a distal end of the movable wire and distal ends of the fixed wires are joined to each other. A proximal end of the movable wire is pulled with the handle portion toward the handle portion so the excluding portion develops a cocoon shape. The retractor is useful in minimally-invasive surgery.||12-05-2013|
|20120280187||FINE METAL PARTICLE-CONTAINING COMPOSITION - A fine silver particle-containing composition includes a large number of fine silver particles||11-08-2012|
|20100236211||RUBBER-PRODUCT-REINFORCING STEEL CORD AND METHOD FOR MANUFACTURING THE SAME - A single-layered rubber-product-reinforcing steel cord with good rubber penetration properties, excellent fatigue resistance, and small low-load stretch is obtained. All of wires||09-23-2010|
|20090103207||ROTOR HUB, SPINDLE MOTOR AND HARD DISK DRIVE - In a method for manufacturing a rotor hub for use in a spindle motor, free-cutting stainless steel is used as a material of the rotor hub. A slug of free-cutting stainless steel is subjected to a plastic working to form a disk mounting portion and a cylindrical surface positioned radially inwardly of the disk mounting portion. Then, a cylindrical disk fitting surface is formed by machining substantially the entirety of the cylindrical surface. The rotor hub contains A-type inclusions appearing in a cross section taken along a center axis of the disk mounting portion. The A-type inclusions are oriented in directions different than the center axis.||04-23-2009|
