  • Publication number: 20220336934
    Abstract: A coin-shaped cell containing a battery cell case having a bottom plate and side portion; a sealing plate; a gasket compressed and interposed between the side and a rim portion; power generation elements sealed by the case, the sealing plate, and the gasket; and a pressure-sensitive conductive film disposed on an outer surface of one of the case and the sealing plate. The pressure-sensitive conductive film includes a first elastomer layer that holds conductive particles, and a second elastomer layer which is disposed on at least one surface of the first elastomer layer and is in contact with at least a part of the conductive particles. An average particle diameter of the conductive particles is equal to or larger than a thickness of an elastomer part of the first elastomer layer, and the conductive particles are disposed in a single layer in a planar direction of the first elastomer layer.

  • Patent number: 11247639
    Abstract: Provided is a wiper blade rubber which has excellent wiping properties and low friction properties with respect to both clean glass surfaces and glass surfaces that have been subjected to a water repellent treatment, and which maintains these properties for a long period of time. A wiper blade rubber which has a lip part wherein a coating layer is provided on a rubber substrate by (a) applying a first coating agent onto a part of the surface of the rubber substrate, (b) curing a first coating layer by heating the rubber substrate onto which the first coating agent is applied, (c) applying a second coating agent onto the surface of the rubber substrate which has the cured first coating layer and (d) drying the second coating agent.

  • Patent number: 10946837
    Abstract: Provided is a wiper blade rubber which exhibits high adhesion to glass surfaces, excellent friction performance and excellent wiping performance, while being free from the occurrence of a bulge (blister) in a coating layer due to bleeding from a rubber substrate or blooming. A wiper blade rubber which has a lip part obtained by forming a coating layer on a rubber substrate by spray coating, and which is characterized in that: the coating layer is composed of a portion (A) that covers the rubber substrate and portions (B) that do not cover the rubber substrate; the portions (B) are a plurality of pores which are uniformly dispersed in the entire area of the coating layer and have diameters of 10 to 40 ?m; and the ratio of the total area of portion (A) that covers the rubber substrate to the total area of the portions (B) that do not cover the rubber substrate is from 40:60 to 60:40.
