| 20110308903 | CABLE-OPERATED DEVICE AND PARKING BRAKE CONTAINING THE SAME - A cable-operated device ( | 12-22-2011 |
| 20110232413 | CONNECTING MEMBER AND CONTROL CABLE - A connecting member includes a male screw portion, a cable insertion portion, a locking portion, and a crimping portion. The male screw portion is provided at a first end of the connecting member. The cable insertion portion is provided at a second end, opposite to the first end, of the connecting member, and has a closed-bottomed hole into which one end of an inner cable is to be inserted. The locking portion is provided on outer circumference of the connecting member between a bottom of the closed-bottomed hole and the second end, and has a shape which can be caught with a part of an operation object in a circumferential direction of the male screw portion. The crimping portion is provided on the outer circumference between the bottom of the closed-bottomed hole and the second end, and configured to crimp the one end of the inner cable. | 09-29-2011 |
| 20110226081 | CONTROL CABLE - A control cable | 09-22-2011 |
| 20110100151 | PUSH-PULL CABLE - A push-pull cable suitable for automotive applications includes an outer cable having a hollow interior and an inner cable having a circular cross section perpendicular to its axial direction. The inner cable is slidably disposed within the hollow interior and grease is disposed in a clearance defined between an outer circumferential surface of the inner cable and an inner circumferential surface of the outer cable. The inner cable consists of a single metal wire coated with a metal plated layer, the plated layer has a thickness between 3 and 35 microns and the clearance is between 0.05 to 0.5 millimeters. | 05-05-2011 |
| 20110074079 | COIL SPRING FOR AUTOMOBILE SUSPENSION AND METHOD OF MANUFACTURING THE SAME - A manufacturing method of a coil spring for an automobile suspension includes forming a material into a coil shape; performing a heat treatment step on the material; performing a warm shot peening step on the material, and performing a hot setting step on the material. By performing the warm shot peening step prior to the hot setting step, a stronger compressive residual stress is imparted in a direction along which a large tensile stress acts during actual use of the coil spring, thereby improving sag resistance and durability of the coil spring. A coil spring is also manufactured according to this method. | 03-31-2011 |
| 20110074078 | SPRING STEEL AND SPRING HAVING SUPERIOR CORROSION FATIGUE STRENGTH - A spring steel and spring having superior corrosion fatigue strength and a strength on the order of HRC 53 to HRC 56 are disclosed. The spring steel comprises a tempered martensite and 2.1 to 2.4% Si in terms of percent by mass of the total mass of the spring steel. | 03-31-2011 |
| 20110074077 | SPRING STEEL AND SPRING HAVING SUPERIOR CORROSION FATIGUE STRENGTH - The present application provides a high strength spring steel and a high strength spring that have superior corrosion fatigue strength. The spring steel comprises, in terms of percent by mass, 0.35-0.55% C, 1.60-3.00% Si, 0.20-1.50% Mn, 0.10-1.50% Cr and at least one element selected from 0.40-3.00% Ni, 0.05-0.50% Mo 0.05-0.50% V, the balance being at least substantially Fe and incidental elements and impurities. | 03-31-2011 |
| 20110074076 | SPRING STEEL AND SPRING HAVING SUPERIOR CORROSION FATIGUE STRENGTH - A high-strength spring steel and a spring are provided that have superior corrosion fatigue strength. The spring steel comprises, in mass percent, 0.35-0.55% C, 1.60-3.00% Si, 0.20-1.50% Mn, 0.10-1.50% Cr, and at least one of 0.40-3.00% Ni, 0.05-0.50% Mo and 0.05-0.50% V, the balance being substantially Fe and incidental elements and impurities. | 03-31-2011 |
| 20110006467 | DISC SPRING AND PROCESS OF MANUFACTURING THE SAME - A metal strip | 01-13-2011 |
| 20100255296 | SPRING WITH HIGH DURABILITY AND METHOD OF COATING THE SAME - A spring with high durability has a coating film composed of an epoxy resin powder coating containing softening agent which contains an epoxy resin and a softening agent comprising a thermoplastic resin for improving impact resistance of the coating film. A method of coating a spring with high durability comprises a coating step of making an epoxy resin powder coating containing softening agent which contains an epoxy resin and a softening agent comprising a thermoplastic resin for improving impact resistance of a coating film adhere to a surface on which the coating film is formed, and a baking step of baking the epoxy resin powder coating containing softening agent adhered to the surface. | 10-07-2010 |
| 20100032631 | Cable-operated device - A cable-operated device may comprise a moving member, a cable, a supporting member, and a coil spring. One end of the cable may be connected to the moving member. The cable may be arranged so as to advance and retreat with respect to the moving member. The moving member may move as the cable is caused to advance and retreat. The supporting member may support the cable along a pathway on which the cable is arranged. One end of the coil spring may be fixed to the moving member, and the other end thereof may be fixed to the supporting member. The cable may be inserted into the inner hole of the coil spring. At least one of the moving member and the supporting member may comprise a guide surface that makes contact with the coil spring from a lateral direction with respect to the coil spring. At least one portion of the guide surface may comprise an alumite film. | 02-11-2010 |
