  • Publication number: 20060087916
    Abstract: A cover member is adapted for use with a food processor, and includes a cover body formed with a straight rod passage and a food passage that branches from the rod passage. The rod passage has an open inner passage portion, and an open outer passage portion opposite to the inner passage portion in a vertical direction. The food passage has an open inlet end adjacent to the outer passage portion of the rod passage, an open outlet end in spatial communication with the inner passage portion of the rod passage, and a guide passage portion between the inlet and outlet ends. The guide passage portion is capable of guiding a food item fed into the food passage via the open inlet end to move into the inner passage portion of the rod passage via the open outlet end.

  • Publication number: 20030054608
    Abstract: The present invention discloses a method for forming shallow trench isolation in a semiconductor device, particularly a nonvolatile memory device. A dielectric layer, an amorphous silicon layer, and a mask layer are sequentially formed over a substrate. Isolation trenches are etched in the substrate through the layers. An oxide layer is thermally grown lining the sidewalls of the amorphous silicon layer and the trenches. Due to the lower oxidation rate of amorphous silicon, the liner oxide layer is thinner at the position lining the amorphous silicon layer than at the position lining the trench. The trenches are filled with an isolation layer to form shallow trench isolation (STI) structures. After removing the mask layer, the amorphous silicon layer can be converted into a polysilicon layer to serve as a floating gate for a nonvolatile memory device.

  • Patent number: 5798681
    Abstract: The garage door position indicator contains a radio frequency (RF) transmitter with an electronic angle sensor attached onto a garage door, and a RF receiver with a visual/audio indicator. The electronic angle sensor supplies signals to the RF transmitter during the changes in orientation of a garage door from vertical to horizontal and from horizontal to vertical. The RF receiver is responsive to the RF signals from the RF transmitter and controls a visual/audio indicator to indicate the position of a garage door accordingly.
