20110270541 | AIR FLOW RATE SENSOR - Disclosed is an air flow rate sensor capable of sensing an air flow rate and respirator air flow rate. The air flow rate sensor includes a chamber having left and right portions having same internal diameters and a central portion having an internal diameter greater than the internal diameters of the left and right portions, first and second pressure taps provided at the left and right portions of the chamber, respectively, and a pressure sensor connected to the first and second pressure taps to measure a differential pressure between the left and right portions of the chamber. There are obstacles on the path of air flow, so that exact and uniform measurement characteristics are maintained. Since energy loss is measured by using vortex, the structure of the air flow rate sensor is simplified. The air flow rate sensor is used as a respirator air flow rate sensor. | 11-03-2011 |

20130227808 | WIPER LEVER ASSEMBLY AND WIPER BLADE - Disclosed herein is a wiper lever assembly which is configured to prevent detachment of end cover members, which includes a lever member (a center cover lever, secondary levers and yoke levers) gripping a rubber blade disposed thereunder, and an end cover member which covers an end of the lever member from above and which includes claws formed on both lateral sides thereof. The claws may be extended inwardly from the end cover and engage with both lateral sides of a lower surface of the lever member to grip the lever member. The end cover member includes a support wall which is formed at the center of a width of the end cover member and is extended downwardly therefrom, and the lever member includes a receptor (an insert tube and a proximal insert tube) in which the support wall is fitted from above. | 09-05-2013 |
20130276255 | WIPER LEVER ASSEMBLY AND WIPER BLADE - Disclosed is a wiper lever assembly that includes upper and lower levers, a plurality of pivotal connecting parts that are pivotally coupled to a longitudinal end of the upper lever, and a plurality of mating pivotal connecting parts that are disposed on the lower lever. The assembly further includes an upper pressing arc portion disposed on the upper lever over the plurality of pivotal pressing parts. The upper pressing arc is in slidable contact with a lower engaging arc portion disposed on the lower lever. In addition, a radius of curvature of a concave arc of the upper pressing arc portion and the lower engaging arc portion is larger than that of a convex arc of the upper pressing arc portion and the lower engaging arc portion. | 10-24-2013 |
