  • Patent number: 6019891
    Abstract: Debris vacuum device including a suction bulb. In a first embodiment the suction bulb includes a hollow tube with an inlet check valve located at one end and an exhaust check valve located at the opposing end. A screen is provided to extend across the interior of the tube intermediate the ends. By squeezing the walls of the tube, water can be forced out the exhaust check valve with the inlet check valve closed. Then as the flexible walls expand to their original shape, water and debris are drawn into the tube to the inlet check valve while the outlet check valve is closed. In a second embodiment, a bulb having a single opening into the interior is used. An inlet tube for drawing debris and water has one end inserted into the interior of the bulb. The bulb opening is also connected to an exhaust port to allow water to be forced out of the interior of the bulb.

  • Patent number: 6020683
    Abstract: A method for fabricating a field emission display (FED) with improved junction leakage characteristics is provided. The method includes the formation of a light blocking element between a cathodoluminescent display screen of the FED and semiconductor junctions formed on a baseplate of the FED. The light blocking element protects the junctions from light formed at the display screen and light generated in the environment striking the junctions. Electrical characteristics of the junctions thus remain constant and junction leakage is improved. The light blocking element may be formed as an opaque light absorbing or light reflecting layer. In addition, the light blocking element may be patterned to protect predetermined areas of the baseplate and may provide other circuit functions such as an interconnect layer.

  • Patent number: 6017776
    Abstract: The present invention is directed to a method of attaching a leadframe to a singulated good die using a wet film adhesive applied in a predetermined pattern on the active surface of the good die, the lead finger of a leadframe, or both. By applying the adhesive only to identified good dice, time and material are saved over a process that applies adhesive to the entire wafer. By attaching the leadframe to the good die with a wet film, it is possible to remove the leadframe from the good die for rework if the good die subsequently tests unacceptable.

  • Patent number: 6017772
    Abstract: A method of fabricating field emission arrays which employs a single mask to define emitter tips and their corresponding resistors. Column lines may also be defined without requiring the use of an additional mask. The method includes disposing substantially mutually parallel conductive lines onto a substrate of the field emission array. The conductive lines may be patterned from a layer of conductive material or selectively deposited onto the substrate. One or more material layers, from which the emitter tips and resistors will be defined, are disposed onto the conductive lines and the regions of substrate exposed between adjacent conductive lines. The exposed surface of the layer or layers of emitter tip and resistor material or materials may be planarized. A mask is disposed over the substanitially planar surface.

  • Patent number: 6010728
    Abstract: A method to promote skin healing of freshly dug potatoes is disclosed. Treatment of freshly dug potatoes with DMN either prior to or immediately after storage promotes rapid healing of cuts, abrasions and similar injuries to the potatoes. Liquid DMN may be sprayed on freshly dug potatoes in the field immediately after being dug, during transport from the field, while being conveyed into a storage facility or immediately after being stored. Once in a storage facility, the potatoes may also be treated with a vapor or mist of DMN either in addition to initial treatments or instead of earlier treatments. Further, such DMN treated potatoes may be stored under low humidity conditions without significant dehydration or softening. Stored potatoes first treated with DMN may be later advantageously treated with low levels of CIPC for effective sprout inhibition.
