  • Patent number: 10222127
    Abstract: A guide plate having depressed portions is provided between an array of heat exchanger tubes, herein after “tubes”, arranged horizontally side-by-side and a next lower array of tubes arranged horizontally side-by-side, and is positioned with the lowest parts of the depressed portions near crest portions of respective lower tubes. The guide plate conveys a liquid D on outer surfaces of respective upper tubes onto similarly positioned lower tubes even when the tubes move in a right-and-left direction. A falling film heat exchanger installed in a ship, an offshore structure or the like can avoid reduction in heat exchange performance, even when the ship or the like inclines and swings, by substantially evenly distributing and dropping a liquid onto the crests of the tubes and causing the liquid dropped from the tubes located in an upper array to fall onto the tubes located in the next lower array.

  • Patent number: 9719528
    Abstract: In a bubble lift system, a pressurized chamber at an upper end portion of a riser pipe applies a pressure to an upper portion inside the riser pipe to suppress an increase in the volume ratio of bubbles to a fluid mixture rising inside the riser pipe in a shallow water region. The upper end of the riser pipe is not opened to the atmosphere but is inserted into the pressurized chamber under a high pressure to thereby prevent expansion of the bubbles and gas. In addition, a deaerator for discharging bubbles separated by a centrifugal force is also provided in a middle portion of the riser pipe in a shallow water region to distribute the bubbles more evenly inside the whole riser pipe. The bubble lift system and a bubble lift method thus provided are efficient and employable even in a deep water region.

  • Publication number: 20140169989
    Abstract: In a bubble lift system 10, a pressurized chamber 21 is provided at an upper end portion of a riser pipe 11, and applies a pressure to an upper portion inside the riser pipe 11 to suppress an increase in the volume ratio of bubbles to a fluid mixture rising inside the riser pipe 11 in a shallow water region. In this configuration, the upper end of the riser pipe 11 is not opened to the atmosphere but is inserted into the pressurized chamber 21 under a high pressure to thereby prevent expansion of the bubbles and gas. In addition, a deaerator 14 for discharging bubbles separated by a centrifugal force is also provided in a middle portion of the riser pipe 11 in a shallow water region to thereby make the bubbles distributed more evenly inside the whole riser pipe 11. Thus, provided are the bubble lift system 10 and a bubble lift method that are efficient and employable even in a deep water region.

  • Patent number: 5535119
    Abstract: An information processing equipment providing easy operations of changing-over character species, and, in which characters can be entered without being conscious of the designation of a character mode. Signals entered from an input device are handled in conformity with all of a romaji (Roman character) input system, a kana (Japanese syllabary) input system and an alphanumeric input system. Results obtained with the respective input systems are all displayed in the predetermined part of a display screen. In the equipment, the character mode intended by a user is estimated as to the entered character string, and is automatically selected. In another aspect of performance, a controller determines whether or not a character mode likelihood decision unit and a character code translation unit are started, in accordance with the results of the comparisons between the key code string and the registered contents of a learning information buffer.

  • Patent number: 5142618
    Abstract: A document creating apparatus for creating and editing a document in which a plurality of different types of descriptive element data, such as text data, graph data, pattern data, image data and other data, coexist. Plural types of edit sections are provided in correspondence with the types of data to be handled. Various types of data are edited under coordination by selecting edit sections corresponding to the types of data, respectively, while maintaining the editing function of the editing section once selected and activated so that the editing section can be selected again without losing its editing function.

  • Patent number: 5003499
    Abstract: The document edition unit includes region set apparatus for setting a size of the region to a size corresponding to the print output, region attribute set apparatus for setting attribute information, region information hold apparatus, and text re-determination apparatus. The text data edition unit includes text input control apparatus. The region information hold apparatus manages the size and position of the region set by the region set apparatus in the size and at the position corresponding to those of at the time of print output, and manages the attributes set by the region attribute set apparatus so as to correspond to them. The text input control apparatus controls the arrangement to the character string at the time of text input by referring to the region information whose position on the page is fixed.
