The pivotal axle is passed through the first pivotal portion of the fixed part and the second pivotal portion of the rotatable part to render the rotatable part rotating relative to the fixed part and with respect to the pivotal axle. Consequently, through the rotation of the cam member, the contacts of the first and second contact faces with a pivoting portion is alternated and thus the distance between the contact faces and the pivotal portion is changed, rendering the nut pressing against or relaxing from at least one elastic part. The axial frictional force generated between the fixed part and the rotatable part is therefore changed so as to achieve positioning or rotation of the fixed part and the rotatable part. | 06-25-2009 |

| 20100263843 | INCLINED WAVED BOARD AND HEAT EXCHANGER THEREOF - An inclined waved board and a heat exchanger thereof. The inclined waved board includes a board body composed of continuous waved sections. The waved sections are respectively inclined from a first side to a second side, inclined from the first side to a third side and inclined from a fourth side to the second side of the board body by an inclination. The waved sections define multiple raised sections and recessed sections on two faces of the board body. The heat exchanger is composed of multiple board bodies arranged adjacent to and in parallel to each other. Each two adjacent board bodies define therebetween a flow way. When fluids flow through the flow ways, the inclined waved sections enhance turbulence intensity and guide the fluids to produce secondary flows along the cross-sections of the flow ways so as to form dynamic three-dimensional swirling flow structure in the waved flow ways. The enhanced turbulence activities and the swirling flow structures augment heat transfer rates with less pressure-drop penalties from the likewise ribbed channel due to the smooth channel surface for the present invention. | 10-21-2010 |
