  • Publication number: 20210345631
    Abstract: Disclosed is a method for producing a rich fermented milk having the original hardness and dense texture of the fermented milk. Disclosed is a method for producing a multi-layer fermented milk of a post-fermentation type, including the steps of: filling a container with a raw material milk to which a starter has been added and a sugar-containing liquid so as not to mix the raw material milk and the sugar-containing liquid, wherein the sugar-containing liquid has an amount of 15.0% by mass or more of the total amount of the raw material milk and the sugar-containing liquid, and the sugar-containing liquid has a solid content of 20.0% by mass or more; and fermenting the raw material milk in the filled container to obtain a multi-layer fermented milk product in a container in which a fermented milk layer having a higher solid content than the raw material milk is formed and a storage modulus G?, which is an index of hardness of the fermented milk, is 1200 Pa or more.

  • Patent number: 7190652
    Abstract: In the disclosed pulse shape modulation method, an amplitude modulation gain for a reproduced signal from an information recording medium that makes the jitter of the reproduced signal become the minimum is specified. Then, it is determined whether the amplitude modulation gain corresponding to the minimum jitter resides within a prescribed range. If the amplitude modulation gain corresponding to the minimum jitter is outside the prescribed range, the pulse shape of the pulsed laser beam is modulated.

    Abstract: Both a low-linear-velocity recording and a high-linear-velocity recording can be effectively performed by an optical recording method for recording information on a phase-change optical recording medium which is recordable at a low linear velocity and a high linear velocity greater than the low linear velocity. A ratio (Pel/Pwl) of an erasing power Pel to a recording power Pwl in the low-linear-velocity recording and a ratio (Peh/Pwh) of an erasing power Peh to a recording power Pwh in the high-linear-velocity recording are determined so that the ratio (Pel/Pwl) and the ratio (Peh/Pwh) satisfy the relationship {(Pel/Pwl)<(Peh/Pwh)}.
