Abstract: ABSTRACT            MANUFACTURING PROCESS OF A CAPACITOR WITH DELAYED AGEING AND A CAPACITOR MANUFACTURED ACCORDING TO THIS PROCESS   The manufacturing process of the capacitor with a polypropylene dielectric film consists in introducing pre-cross-linking elements of the polypropylene at the time of manufacturing. When the capacitor is used, the electrical field and/or temperature generated trigger the cross-linking process of the poly-propylene, delaying and slowing down the ageing phenomena, i.e. the decrease of the dielectric strength. The pre-cross-linking agent  is a polyfunctional monomer to which an activation accelerator and/or a stabilizing agent can be added.

Title: A method and an electrode system for heating media flowing through an insulating pipe
Inventor: PEDERSEN IB O
IPC: H05B6/54
Filed: 1992-05-27
Abstract: A method of heating media flowing through an insulating pipe by means of high-frequency electrical power. The medium is fed through a pipe of a substantially electrically non-conducting material and only presenting minor dielectric losses, and around which two ring electrodes are arranged at such a mutual axial distance that the two electrode rings are mutually spaced by a predetermined pipe length connecting said electrodes to the terminals of an HF  generator and applying an HF voltage from the HF generator. In this manner a uniform and efficient heating is obtained of the flowing medium or fluid (granulate, liquid or gas) without said medium necessarily getting into direct contact with a heating means and without said medium escaping from its conveying pipe. The latter is very advantageous in connection with many uses, such as when toxic or aggressive media apply, and also when sensitive media are involved which do not endure getting in contact with the atmosphere.

Title: Manufacturing method of a separator for a lithium secondary battery and an organic electrolyte lithium secondary battery using the same separator
Inventor: MORIGAKI KENICHI
IPC: H01M50/497
Filed: 1994-10-07
Abstract: This invention relates to an organic electrolyte lithium secondary battery wherein lithium works as an active material, and comprises a negative electrode made of metallic lithium or lithium alloy, and relates more particular to a separator of the same battery. A conventional battery uses a separator made of polyethylene and/or poly propylene, however, this invention uses microporous polyolefin membrane as a separator matrix whose pores are filled and closed with ionic conductive gel electrolyte. The separator uses a sheet whose at least one face contacting the negative electrode has a gel electrolyte layer on it.   The gel electrolyte is formed by irradiating ultraviolet ray to a mixed solution wherein a mixture of which major components are oligomer and monomer polymerized by ultra violet ray is added to organic electrolyte.        By using the separator according to this invention in an organic electrolyte lithium secondary battery, internal short circuits due to dendrited lithium growing on a negative electrode during a charge can be prevented, and a longer cycle life is expected. Further, burning accidents can be reduced. A highly reliable lithium secondary battery can be thus achieved.      Note: The expression "dendrited lithium" means that metal lithium deposited on a negative electrode grows in a form of (or in a shape of) dendrite.
