| 20080258210 | SEMICONDUCTOR COMPONENT AND METHOD OF MANUFACTURE - A semiconductor component resistant to the formation of a parasitic bipolar transistor and a method for manufacturing the semiconductor component using a reduced number of masking steps. A semiconductor material of N-type conductivity having a region of P-type conductivity is provided. A doped region of N-type conductivity is formed in the region of P-type conductivity. Trenches are formed in a semiconductor material and extend through the regions of N-type and P-type conductivities. A field oxide is formed from the semiconductor material such that portions of the trenches extend under the field oxide. The field oxide serves as an implant mask in the formation of source regions. Body contact regions are formed from the semiconductor material and an electrical conductor is formed in contact with the source and body regions. An electrical conductor is formed in contact with the backside of the semiconductor material. | 10-23-2008 |

| 20090288679 | Apparatus and method for cleaning surfaces - The apparatus for cleaning surfaces of the present invention such as for cleaning solar collectors preferably alternates different fluids and gas decompression to create a cleansing fluid evacuation to clean outdoor solid surfaces. The method of the present invention utilizes alternating fluids in order to avoid mineral deposits contaminating the collector. The apparatus of the present invention is a tool to achieve the ends of the method. The apparatus preferably uses copper piping and turbulence to regulate water flow and to create the high velocity fluid evacuation that achieves the ends of the method invention. The use of a constant pressure pump and turbulence inducing fibers allows passive regulation of pressure that is equalized across a plurality of sprayers to deliver an even amount of high velocity fluid from each sprayer. Sonication accelerates cleaning, rinsing or snow/ice removal. | 11-26-2009 |

| 20110192207 | AUTOMATIC EXTRUSION DEVICE - An automatic extrusion device includes a main body, a driving unit, a first transmission unit, a second transmission unit and an extrusion unit. The second transmission unit has a clutch slip function for the automatic extrusion device to extrude the front of the pipe to be in the form of a bell for a fast connection of pipes. Through the slip function of the second transmission unit, it not only prevents the extrusion unit from over extrusion but also makes the front end of the pipe round so as to beautify the interface of the pipe. | 08-11-2011 |

| 20120074686 | CONNECTOR FOR AN OIL DRAIN VALVE - A connector for an oil drain valve has a body and a locking arm. The body has a sleeve and two pivotal ears separately formed on and protrude from the outer surface of the sleeve. Each pivotal ear has a pivotal hole and a locking hole. The locking arm is pivotally mounted between the pivotal ears and has a cam segment and a locking hole. The cam segment is formed on one end of the locking arm and is eccentric to a pivoting hole in the locking arm. The locking hole is formed through the locking arm and selectively aligns with the locking holes in the pivotal ears of the body. Accordingly, the connector can provide an excellent sealing effect and keep the connector disengaging unintentionally from the oil drain valve during the oil-draining process. | 03-29-2012 |
