  • Publication number: 20210288009
    Abstract: A method of forming an integrated circuit structure includes forming a patterned passivation layer over a metal pad, with a top surface of the metal pad revealed through a first opening in the patterned passivation layer, and applying a polymer layer over the patterned passivation layer. The polymer layer is substantially free from N-Methyl-2-pyrrolidone (NMP), and comprises aliphatic amide as a solvent. The method further includes performing a light-exposure process on the polymer layer, performing a development process on the polymer layer to form a second opening in the polymer layer, wherein the top surface of the metal pad is revealed to the second opening, baking the polymer, and forming a conductive region having a via portion extending into the second opening.

  • Patent number: 6937684
    Abstract: A differential phase discriminator includes a phase compensation circuit to compensate for timing drift and error for recovering timing information in a digital phase lock loop. The differential phase discriminator uses a differential phase detector to compute the phase difference of two consecutive frequency domain signal samples. The phase compensation circuit determines a phase correction term by computing the difference between the absolute values of the real and imaginary parts of a frequency domain signal sample. A weighting factor is computed by adjusting the sum of the absolute values of the real and imaginary parts of the frequency domain signal sample with a ratio adjustment factor. A phase compensation value is then computed by multiplying the phase correction term by the weighting factor. The phase compensation value is added to the uncorrected output of the differential phase detector.

  • Patent number: 6079474
    Abstract: A sun-shade assembly includes a stationary curved shaft, a tubular roller, a screen, and a torsion spring. The roller is made of a resilient material, and is sleeved rotatably around the shaft. The roller has a curvature conforming with that of the shaft. The screen is wound around the roller, and has a lower edge connected to the roller and an upper edge provided with a stretch rod which has a curvature conforming with that of the shaft. The torsion spring has a first end secured to the roller, and an opposite second end secured to the shaft. The screen is unwound from the roller when the stretch rod is pulled away from the roller, thereby resulting in rotation of the roller about the shaft in a first direction against biasing force of the torsion spring. The torsion spring biases the roller to rotate about the shaft in a second direction opposite to the first direction to result in winding of the screen onto the roller.

  • Patent number: 5791721
    Abstract: A motorized sun screen for covering a vehicle window has a base unit and a screen unit which includes a lower horizontal rod mounted rotatably on the base unit, an upper horizontal shaft and a screen with a bottom edge connected to the horizontal rod and a top edge connected to the horizontal shaft. Each of a pair of pivot arms has a lower end portion mounted pivotally on the base unit and an upper end portion slidably engaging the horizontal shaft. An extension spring has two ends connected respectively to the lower end portion of the pivot arms. A drive unit is mounted on the base unit and includes a motor with a rotatable drive shaft which is coupled to one end of the horizontal rod. The motor is operable in a first mode, wherein the motor permits the extension spring to contract, thereby causing the pivot arms to pivot away from each other to move the horizontal shaft upwardly and stretch the screen.

  • Patent number: 5361568
    Abstract: A lawn mower includes a blade support with a recess formed in the bottom side thereof and an outlet portion. A blade is mounted rotatably within the recess. A grass collecting unit has an inlet portion communicated with the outlet portion of the recess so as to collect grass that was cut from a lawn with the use of the blade. Several ventilation holes are formed through a wall of the grass collecting unit so as to reduce air pressure inside the grass collecting unit. The grass collecting unit has a positioning hole formed through the top wall thereof. A grass indicating unit includes a body member disposed in the positioning hole and capable of being pushed upward relative to the top wall of the grass collecting unit by virtue of air pressure inside the grass collecting unit, and a positioning assembly mounted securely on the body member so as to prevent removal of the body member from the top wall of the grass collecting unit.
