  • Patent number: 6339804
    Abstract: A digital information reproduction apparatus for compressing frames of data so as to intermittently reproduce the data in fast-forward speed. A data re-write device retrieves a reproduction-target frame for the fast-forward reproduction and a parameter-calculation-target frame exclusively for calculation of the frame data parameters. The frames then are transferred to a RAM. A decoder determines the frame data in the RAM, calculates the parameter-calculation frame data, and decodes the reproduction frame data by use of the parameter obtained as above. The described operation prevents expending the reproduction frame data with an incorrect parameter so as to normally fast-forward reproduce the compressed data. Furthermore, the present can select a frame used in the fast forward reproduction according to a feature index so that a section subjected to the fast-forward reproduction can be easily grasped by the user.

  • Patent number: 6321566
    Abstract: Liquid oxygen, which is extracted from the bottom of a lower pressure rectifier and compressed by a liquid oxygen pump to a predetermined supply pressure, is evaporated in a main heat exchanger to prepare an oxygen gas product, while oxygen gas is circulated in the main heat exchanger at a linear velocity which is equal to or higher than the terminal velocity, calculated depending on the supply pressure, of an oxygen droplet having a diameter of 200 &mgr;m. This process effectively prevents precipitation of heavy impurities in the heat exchanger and produces higher pressure oxygen gas at reduced operational costs.
