20080298729 | LINEAR MOTION GUIDE UNIT WITH ROLLERS - A linear motion guide unit with high stiffness, high accuracy and long-lasting service life is provided in which a rolling element is a roller and a carriage of a slider is made long to allow a crowning profile to be long. The carriage has an overall length equivalent to substantially four times a width of a guide rail. The carriage is made thereon with a raceway surface that is modified near lengthwise opposite ends thereof crowning profiles each of which has a crowning length equivalent to four times as long as a diameter of the roller and also has a crowing depth equivalent to an amount of elastic deformation that occurs in the raceway surfaces and the roller when the slider undergoes a load reaching a half of a static nominal standard load. | 12-04-2008 |
20090016654 | LINEAR MOTION GUIDE UNIT WITH ROLLER - A linear motion guide unit is envisaged smooth transfer of a roller from a turnaround passage to a return passage and vice versa across a joint between the turnaround passage and the associated return passage. Protrusions extending stepwise from an end of the turnaround passage come into complementary fit joints with an associated end of a tubular member defining the return passage to make wall surfaces to guide axially opposite ends of the roller, in which the joints are staggered or different in their locations between wall surfaces. The return passage is defined with a fore-and-aft hole of rectangular shape in transverse section inside a tubular member that fits into a bore made in the carriage. The tubular member is joined at lengthwise opposite ends thereof together to the protrusions that are raised above end surfaces of the end caps to extend the turnaround passage into the bore. Edges of the protrusions come into complementary fit joints with the associated ends of the tubular member to provide wall surfaces to guide axially opposite ends of the roller. | 01-15-2009 |
20090052815 | LINEAR MOTION GUIDE UNIT WITH MOUNTING PLATE - A mounting plate is used to install any optional accoutrements or attachment on a linear motion guide unit. The mounting plate is made of a molded product which is inexpensive in production cost and easier in its accurate conjunction with a slider to get the attachment bringing out the best in function. The mounting plate is made to have surfaces opposite to each other, one of which is a first mounting surface inward coming into mating with the one end surface of the slider and another is a second mounting surface outward coming into mating with the attachment. The mounting plate is made of a molded product. The mounting plate is made of an injected mold product of synthetic resin which is composed of a major part of synthetic resin and a metal core centrally embedded in the major part. | 02-26-2009 |
20100074564 | LINEAR MOTION GUIDE SYSTEM WITH WIPER SEAL - A wiper seal is less in sliding resistance that is encountered when the seal slides over a raceway surface of a guide rail, better in wear-proof quality, rich in durability, and further easy to steadily install it to a slider. The wiper seal is installed on one end of the slider in a linear motion guide system to wipe away foreign materials adhered on the guide rail. The wiper seal is made of polyester polyurethane foam having a reticular skeleton texture of three-dimensional construction including open-cells therein, the polyester polyurethane foam being squeezed or compressed into from ¼ to 1/20 in thickness to form a compact blank of three-dimensional construction having porosity therein. The wiper seal is set to come into sliding contact with the guide rail | 03-25-2010 |

20090242256 | ELECTRONIC COMPONENT AND ELECTRONIC COMPONENT MODULE - In a dielectric element, the angle θ made by either the top face or the bottom face and the side faces is either 0°<θ<89°, or is 91°<θ<180°, and is an angle other than 89°≦θ≦91°. By this means, the area of contact of the side faces of the dielectric element with a glass epoxy resin substrate and with insulating material is increased, adhesion with the resin substrates is improved, and strength and reliability can be enhanced when buried between the two resin substrates. | 10-01-2009 |
20090242257 | ELECTRONIC COMPONENT AND ELECTRONIC COMPONENT MODULE - In a dielectric element, the side faces are roughened so that the surface roughness Ra is 15 nm or greater. By this means, the area of contact between a glass epoxy resin substrate and insulating material is increased, adhesion with resin substrates is improved, and strength and reliability can be enhanced when buried between two resin substrates. In the dielectric element, the surface roughness Ra of side surfaces is 5000 nm or less, so that when burying the dielectric element between a glass epoxy resin substrate and insulating material, the occurrence of air bubbles between the surface of the dielectric element and the resin can be prevented. | 10-01-2009 |
20100260981 | DIELECTRIC DEVICE AND METHOD OF MANUFACTURING DIELECTRIC DEVICE - A dielectric device comprises a substrate made of a metal and an oxide dielectric layer mounted on a surface of the substrate. The surface of the substrate has metal oxide regions distributed like islands, while the oxide dielectric layer is in close contact with the substrate through the metal oxide regions. Since adhesion is higher in an area where the substrate and the oxide dielectric layer are in close contact with each other through the metal oxide regions distributed like islands on the surface of the substrate, the adhesion between the substrate and oxide dielectric layer in the dielectric device is enhanced. As compared with a case where a rough surface is formed on a metal foil, the metal oxide region and the substrate are inhibited from forming a rough surface, whereby leakage characteristics can be kept from being deteriorated by the rough surface. | 10-14-2010 |
