  • Patent number: 8956742
    Abstract: A battery separator includes a porous base material and a heat-resistant layer. The porous base material includes a first surface, a second surface opposed to the first surface, and a hole. The hole is formed in the porous base material and causes the first surface and the second surface to communicate with each other. The heat-resistant layer is configured to cover at least the first surface and a surface of the hole. The heat-resistant layer is formed of an inorganic material and deposited by an atomic layer deposition method.

  • Patent number: 8304009
    Abstract: A method is provided for producing a processed tomato product having more tomato aroma inherent to grown tomatoes. Tomato fruits are washed and crushed. Juice is extracted from the crushed material, the extracted juice is deaerated and the deaerated material is heated. The crushed material and the extracted juice from immediately after the crushing until immediately before the deaerating are maintained at temperature of 15-40° C. The dissolved oxygen concentration of the crushed tomatoes and/or the extracted juice from immediately after the crushing until immediately before the deaerating is raised at least temporarily to 6 mg/L or over, and the dissolved oxygen concentration of the deaerated juice immediately before the heating is reduced to 3.5 mg/L or below.

  • Publication number: 20110159186
    Abstract: The present invention provides a film forming apparatus and a film forming method realizing improvement in the degree of freedom in film formation while suppressing production cost. While conveying a base material by using a plurality of guide rolls, film formation is performed by atomic layer deposition by outputting precursor gases to the base material by a plurality of ALD heads. The ALD heads are disposed so as to individually face the guide rolls so that the precursor gases are locally output to the base material. The amount of the precursor gases used is reduced more than that in a related art, and the variety of kinds of the usable precursor gases is widened.

  • Publication number: 20010003616
    Abstract: A magnetic recording medium comprising a thin magnetic metal film of which the thickness and remanent magnetization are smaller than ever and optimized to match the characteristics of the MR read head used with the recording medium. The thin magnetic metal film is formed on a nonmagnetic substrate and has a remanent magnetization and film thickness product Mr·&dgr; of 1 to 5 memu/cm2. Owing to this product Mr·&dgr;, a signal recorded on the magnetic recording medium can be reproduced with no distortion in a region where the MR read head maintains its linearity.
