Abstract: PURPOSE:To obtain an extremely excellent anti-blocking property, by providing a layer of a material obtained by cross-linking and hardening a specified polysiloxane having a terminal vinyl group by active radiations in a predetermined thickness on the side on which heat is applied. CONSTITUTION:The layer of a material obtained by cross-linking and hardening a polysiloxane having a terminal vinyl group with eta=2-1,000,000 of general formula (1), (2), or (3), wherein A is -CH=CH2, Me is methyl and Ph is phenyl, by active radiations is provided on the side on which heat is applied.

Title: Manufacture of secondary battery negative electrode
Inventor: AKAGI RYUICHI
IPC: H01M10/0565
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To reduce the electric resistance of a negative electrode containing silicon as active material and more thin a battery by forming a negative electrode coating film containing silicon on an organic polymer film followed by baking. SOLUTION: To manufacture a nonaqueous secondary battery thin film negative electrode, a binder and a solvent are added to a negative electrode material containing silicon to prepare a slurry. The slurry is then applied onto a base material consisting of an organic polymer film, and the solvent is removed to produce a coating film. The coating film is further baked under non- oxidizing atmosphere to carbonize or burning the organic polymer film and also sinter the negative electrode material. The coating film is formed on the organic polymer film and then baked to carbonize or burn the organic polymer film, whereby the sintered body of the coating film consisting of the negative electrode material can be manufactured. Further, since the carbonized organic polymer film improves the conductivity of the sintered body, the contact resistance with a current collector can be reduced.

IPC: B41J2/335
Filed: 1988-06-13
Abstract: PURPOSE:To obtain a thermal recording head reduced in power to be applied and generating no damage of an electrode part and a heat generating part by flattening the upper surface of the heat generating part to position the same above the upper surface of the electrode part. CONSTITUTION:In a thermal head, an electrode part 51 is constituted of an electrode film 18 and the protective film 20 on the electrode film 18 while a heat generating part 21 is constituted of a heat generating resistor 19 and the protective film 20 on said heat generating resistor 19. The upper surface of the heat generating part 21 is flat and the diameter of a drum 22, around which recording paper 26 consisting of printing paper 23 and ink paper 24 is wound, is far larger than the length (l) of said upper surface and, therefore, the contact of the heat generating part 21 with the recording paper 26 is regarded as plane-to-plane contact and, even when the rigidity of the recording paper 26 is high and hard to deform, almost uniform contact pressure is obtained over the total length of the heat generating part 21. Therefore, an image print of high image quality can be obtained and, since the contact pressure with the recording paper does not become excessive locally, there is no possibility damaging the electrode part and the heat generating part and, further, since the electrode part is not brought into contact with the recording paper, the power applied to the head is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a driver being driven at high frequency and high speed. SOLUTION: A moving member 26 is supported slidingly on a fixed shaft 14 and a piezoelectric element 22 arranged along the fixed shaft 14 is boded, on one end face thereof, to the moving member 26 and, on the other end face 22a thereof, to a drive frictional member 32.
