  • Publication number: 20210363996
    Abstract: A liquid pressurizing apparatus, comprises a tank provided on a device installation surface for storing liquid so that a fluid level is located above the device installation surface; and a vertical pump including a suction port connected to the tank, multi-stage impellers arranged in a vertical direction, and a discharge port for discharging the liquid passing through the multi-stage impellers. The multi-stage impellers include a first stage impeller positioned at the lowest part of the multi-stage impellers and being configured such that the liquid from the suction port flows into the first stage impeller. The first stage impeller is disposed below the device installation surface.

  • Publication number: 20090073845
    Abstract: An optical recording medium using Sn as the recording material to improve the jitter is provided, in which on the surface of a disc substrate 11 where a concave and convex shape dividing a track area is formed, are formed on the surface of the concave and convex shape a first protective layer 31 for protecting at least an optical recording layer 31, an optical recording layer 12 using a chemical compound at least composed of tin (Sn), nitrogen (N) and oxygen (O), formed on the first protective layer, a second protective layer 32 for protecting this optical recording layer, formed on this optical recording layer, and a light-transmittable layer 13 formed on the second protective layer; with this structure, the optical recording layer 12 under high temperature and high humidity can be stabilized by means of the first and second protective layers 31 and 32.
