Title: Claude Ganguillet: Innovator in Electrochromic Technology
Introduction
Claude Ganguillet is a notable inventor based in Neuchatel, Switzerland. He has made significant contributions to the field of electrochromic technology, holding a total of 3 patents. His work focuses on innovative solutions that enhance the functionality and efficiency of electronic devices.
Latest Patents
One of his latest patents is for an electrochromic display cell. This invention comprises a frame interposed between an ionic conductor and an annular soldered zone that seals a cover of the cell to its substrate. The frame is squeezed between the cover and the substrate to tightly separate the ionic conductor and the solder, preventing any reaction between them. In a preferred embodiment, the frame is made of a thermofusible material that partially melts during the sealing process, adhering tightly to both the cover and the substrate.
Another significant patent involves a masking agent for the deposition of a material and the method for its application. To prepare a temperature-resistant masking agent, silica powder is added to a photoresist. This mixture is used to produce selective deposition of a layer of material on a substrate. The photo-sensitive protective material is partially eliminated through selective exposure to light and the use of a photographic developer. The temperatures involved in the deposition process can reach about 500 degrees Celsius, necessitating the inclusion of silica powder to prevent destruction of the photo-sensitive material.
