  • Publication number: 20090283368
    Abstract: An elevator group control system includes a reference route generating portion, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and an assignment portion which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Reference routes which guide the cage's trajectory into temporally equal interval condition are generated, and car assignment is executed to allow the cages to settle in temporally equal interval condition over a long period of time.

  • Patent number: 7562746
    Abstract: A method and a display for elevator allocation evaluating are provided. When an elevator allocated to a hall call is selected by employing two different view points such as a real and a future call evaluation index, an elevator allocation reason and a balance between the two view points can be easily grasped. An elevator allocated to a hall call is evaluated on orthogonal coordinates in which the real call evaluation index and the future call evaluation index are defined as an X and a Y coordinate axis. Evaluation indexes of first to fourth elevator cars are evaluated by employing contour lines of a synthetic evaluation function, which is represented as the real and the future call evaluation index. A weight for allocating is displayed visually.

  • Patent number: 7426982
    Abstract: An elevator group control system is provided which stably keeps cage's position in temporally equal interval condition over a long period of time. The present invention provides a system comprising: reference route generating means, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and assignment means which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Since reference routes which guides the cage's trajectory into temporally equal interval condition are generated and car assignment is executed so as to make the respective cages follow their reference routes, it is possible to allow the cages to settle in temporally equal interval condition over a long period of time.

  • Publication number: 20080026251
    Abstract: In an insulating film formation method, a cycle A in which O3 at a low flow rate is supplied onto a substrate and then O3 supplied is allowed to react with Hf on the substrate in a non-equilibrium state to form a hafnium oxide film is carried out M times (M?1), and a cycle B in which O3 at a high flow rate is supplied onto the substrate and then O3 supplied is allowed to react with Hf on the substrate in an equilibrium state to form a hafnium oxide film is carried out N times (N?1). These insulating film formation cycles are defined as one sequence. This sequence is repeated until a desired thickness is obtained, thereby forming a target insulating film.

  • Publication number: 20080017954
    Abstract: A capacitor insulating film composed of a layered film of first- to third-layer hafnium oxide films is formed on a lower electrode of a capacitor. The first- and third-layer hafnium oxide films have a composition ratio of oxygen to hafnium higher than the second-layer hafnium oxide film. Thus, the capacitor insulating film is composed of the first- and third-layer hafnium oxide films having greater barrier height and the second-layer hafnium oxide film having a higher dielectric constant, thereby attaining a capacitor having less leakage current and large capacity.
