Title: Method and apparatus for recovering power from semiconductor circuit using thermoelectric device
Inventor: SUSKI EDWARD D
IPC: H01L23/38
Filed: 1995-03-20
Abstract: An apparatus and method for recovering power dissipated by a semiconductor integrated circuit (12) includes a thermoelectric generator (50) which converts the heat generated by the integrated circuit (12) into electrical energy. The electrical energy is used to drive a fan (42) or other airflow generating device to cause heated air to be moved away from the integrated circuit (12) and cooler air to be drawn to the integrated circuit (12) to absorb further heat from the integrated circuit (12). In the described embodiment, the thermoelectric generator (50) is a Peltier cooler positioned between the integrated circuit (12) and a heatsink (60). The Peltier cooler is operated in the Seebeck mode to generate power in response to the temperature differential between the integrated circuit (12) and the heatsink (60). The fan (42) is positioned proximate to the heatsink (60) to cause airflow over the heatsink (60) thereby reducing the temperature of the heatsink (60) and thus reducing the temperature of the integrated circuit (12) by causing more heat to be transferred from the integrated circuit (12) to the heatsink (60).

Abstract: The present invention pertains to an electron gun. The electron gun comprises an RF cavity having a first side with an emitting surface and a second side with a transmitting and emitting section. The gun is also comprised of a mechanism for producing  an  oscillating  force  which  encompasses  the emitting surface and the section so electrons are directed between the emitting surface and the section to contact the emitting surface and generate additional electrons and to contact the section to generate additional electrons or escape the cavity through the section. The section preferably isolates the cavity from external forces outside and adjacent the cavity. The section preferably includes a transmitting and emitting screen. The screen can be of an annular shape, or of a circular shape, or of a rhombohedron shape. The mechanism preferably includes a mechanism for producing an oscillating electric field that provides the force and which has a radial component that prevents the electrons from straying out of the region between the screen and the emitting surface. Additionally, the gun includes a mechanism for producing a magnetic field to force the electrons between the screen and the emitting surface. The present invention pertains to a method for producing electrons. The method comprises the steps of moving at least a first electron in a first direction. Next there is the step of striking a first area with the first electron. Then there is the step of producing additional electrons at the first area due to the first electron.  Next there is the step of moving electrons from the first area to a second area and transmitting electrons through the second area and creating more electrons due to electrons from the first area striking the second area. These newly created electrons from the second area then strike the first area, creating even more electrons in a recursive, repeating manner between the first and second areas.

Abstract: A method for the manufacture of tape tab stock that may be used to produce tape tabs for use with disposable absorbent articles, as well as a method for the on-line manufacture of tape tabs that may be manufactured concurrently with the chassis of the absorbent article to which the tape tabs will be attached. The first step is to provide a backing substrate upon which the adhesives of the tape tab can be applied. Once the backing is provided, a pressure-sensitive adhesive is applied to regions of one side of the backing substrate. (The pressure-sensitive adhesive preferably functions as the adhesive used to fasten an element of the absorbent article, such as a front waist region, to another element of the absorbent article, such as a rear waist region). The backing substrate is then slit in a direction parallel to the machine direction and the release surface of a release substrate is placed in contact with the pressure-sensitive adhesive, forming a laminate comprising the backing substrate and the release substrate. The release substrate preferably covers the entire surface of the backing substrate upon which pressure-sensitive adhesive has been applied. However, in a preferred embodiment, at least a portion of the backing substrate extends outwardly in a direction parallel to the cross machine direction beyond the longitudinal edges of the release substrate. The surface of the laminate, including the surface of the release substrate that is not in contact with the pressure-sensitive adhesive, and any of the backing substrate not covered by the release substrate is then coated with a construction adhesive. (The construction adhesive is used to join the tape tabs to the absorbent article). After the construction adhesive is applied to the surface of the laminate, the laminate is slit in a direction parallel to the machine direction and either rewound for shipping or storage, or fed to a taper unit that is integrated into the absorbent article manufacturing line. The taper unit cuts individual tape tabs and applies them to the absorbent article chassis.
