Both of the ridge and groove are in the shape of curves as viewed in a direction perpendicular to the respective connecting surface. The curve shape may be circular, elliptical, or polygonal.
Abstract: A track pin bushing for cooperating with a track pin in an endless track has a tubular body with a metallurgically bonded wear-resistant coating and a method for forming such a coated track pin bushing is taught herein. The tubular body, formed of an iron-based alloy, has an outer surface that is carburized and quenched, i.e., case-hardened, in at least a section thereof. At least a portion of the case hardened section has been removed to a depth sufficient to expose a non-carburized layer of the iron-based alloy. A hard metal alloy slurry is disposed on the non-carburized layer and forms a metallurgical bond between the non-carburized layer and the coated unfused slurry by fusing the hard metal alloy. The thickness of the unfused slurry is adjusted to be from 1.67 to 2.0 times a final thickness of the wear-resistant coating. The wear-resistant coating comprises a fused, metal alloy comprising at least 60% iron, cobalt, nickel, or alloys thereof.

Abstract: A drilling tool set includes a plurality of drilling tools having different operative drill diameters to blast drill holes of different respective diameters. Each drilling tool of the set has a basic body defining a central axis of rotation, and two replaceable indexable bits including a center bit and a periphery bit which are mountable in respective center and periphery pockets formed in a front end of the basic body. The periphery bits of the respective drill tools of the set are identical, and the center bits of the respective drill tools of the set are identical. Each of the center and periphery pockets of each drill tool defines a radial center point. A first of the drill tools has a smaller operative drill diameter than a second of the drill tools. The first tool includes a first periphery pocket and a center pocket. The center point of the first periphery pocket is disposed closer to the axis than is the center point of the second periphery pocket.
Abstract: An electrode lead, which is used as an implantable electrode lead and a symptom of disconnection of which can be found and detected at an early stage before complete disconnection. Also, an implantable medical instrument which uses this electrode lead safely is provided. More specifically, in an implantable electrode lead obtained by connecting conductor wires 23 and 27 with large electrical resistances and conductor wires 20 and 26 with small electrical resistances parallel to each other, when one of the low-strength conductor wires 20 and 26 is disconnected, a change in electrical resistance of the implantable electrode lead can be detected and informed. Hence, a symptom before total disconnection of the implantable electrode lead can be detected.
Abstract: Provided is a memory device formed using quantum devices and a method for manufacturing the same. A memory device comprises a substrate; a source region and a drain region formed in the substrate so as to be separated from each other by a predetermined interval; a memory cell which is formed on the surface of the substrate to connect the source region and the drain region, and has a plurality of nano-sized quantum dots filled with material for storing electrons; and a control gate which is formed on the memory cell and controls the number of electrons stored in the memory cell. It is possible to embody a highly efficient and highly integrated memory device by providing a memory device having nano-sized quantum dots and a method for manufacturing the same.
