Title: Method of filling a seam of a panel assembly using a thixotropic polyurethane elastomeric filler adhesive
Inventor: MERSER N KEITH
IPC: B01F5/06
Filed: 1997-05-29
Abstract: A method of filling a seam of a structural panel assembly utilizes a non-foaming, thixotropic, two-component polyurethane elastomeric material. The thixotropic, elastomeric material is prepared by rapidly mixing and initiating the reaction of a first thixotropic component comprising an isocyanate-terminated compound having at least two reactive isocyanate groups and a second thixotropic component comprising a hydroxyl-terminated compound having at least two reactive hydroxyl groups. Each of the first and second thixotropic components include from about 3% to 8% by weight fumed silica. The second thixotropic component also includes from about 10% to about 50% filler. The thixotropic elastomeric material is applied over the seam of a panel assembly. The method then includes fluidizing the thixotropic elastomeric material and driving the thixotropic elastomeric material into the seam of the panel assembly. The thixotropic elastomeric material is then allowed to cure in the seam, thereby sealing and reinforcing the seam of the panel assembly.

Inventor: FULTON FORREST F
IPC: H04J3/06
Filed: 1995-12-21
Abstract: A bidirectional radio system for low cost high throughput accumulation of data from a large number of sites units (50). Frequency synchronisation is achieved at low cost by transmitting a hig accuracy carrier and clock signal at a base station (44), and using receiving circuitry at remote stations (46) to extract the base clock signal and base carrier frequency and a phase lock loop (242, 248, 254, 258) to stabilize the remote station carriers. A burst demodulator (156) at a base station receiver can decode a short remote station response by scaling the response with the phase and amplitude of an initial segment of the response. The burst demodulator (156) may continuously update the decoding threshold based on a comparison of the signal amplitude and the current value of the decoding threshold.

Title: Method for creating via hole in chip
Inventor: MOU TSE-CHI
IPC: H01L21/768
Filed: 1998-10-21
Abstract: A method for creating via holes in a chip or a plurality of chips of a wafer is disclosed. The method is performed by using a pre-patterned transparent mask on the back of the chip, and bombarding the chip(s) through the positioning holes of the transparent mask corresponding to the pre-formed pattern with accelerated particles. According to this method, via holes can be created from the back of the chip(s) without interfering with the existent IC structure of the chip(s). The present method is highly efficient because a number of via holes can be formed simultaneously by using a large pre-patterned mask to cover the entire wafer. In addition, the present method is cost-effective because no precision apparatus is required.
