20140216583 | WATER DRAIN ACCELERATING DEVICE - A water drain accelerating device has a base with a discharge port connected to a flush way assembled inside a water tank. An overflow hole is connected to the discharge port. An overflow pipe is plugged to the base. The bottom of the overflow pipe is connected to the overflow hole. A negative pressure pipe is connected to the overflow pipe. Negative pressure generates inside the overflow pipe when the base is draining. Water inside the water tank flows out of the discharge port when water drains. The water level inside the cavity of the negative pressure pipe falls down with the water level inside the water tank. Negative pressure generates inside the overflow pipe, so air inside the overflow pipe can't enter into the discharge port through the overflow hole. An air pipe extends from the overflow hole to the flush way. | 08-07-2014 |

20080201686 | METHOD AND APPARATUS FOR PERFORMING TARGET-IMAGE-BASED OPTICAL PROXIMITY CORRECTION - A system that performs target-image-based optical proximity correction on masks that are used to generate an integrated circuit is presented. The system operates by first receiving a plurality of masks that are used to expose features on the integrated circuit. Next, the system computes a target image for a target feature defined by the plurality of masks, wherein mask features from different masks define the target image. The system dissects the feature into a plurality of segments, wherein dissecting the mask feature involves using dissection parameters associated with geometric characteristics of the target image, instead of using dissection parameters associated with geometric characteristics of the mask feature. The system then performs an optical proximity correction (OPC) operation on the plurality of masks, wherein the OPC operation uses parameters associated with geometric characteristics of the target image to perform optical proximity correction on the mask features that define the target image. | 08-21-2008 |

A proximity effects model is executed to produce an initial output. The initial output is based on a first position for a segment in a fabrication layout. The first position is displaced from a corresponding original edge in the original fabrication layout by a distance equal to an initial bias. The model is also executed to produce a second output based on a second position for the segment. The second position is displaced from the corresponding original edge by a distance equal to a second bias. An optimal bias for the segment is determined based on the initial output and the second output. The segment is displaced in the fabrication layout from the corresponding edge based on the optimal bias. | 10-01-2009 |
