  • Patent number: 11952242
    Abstract: A guiding device according to the present invention generates and displays guidance information for displaying a sequence of operation states of an elevator on a three-sided frame corresponding to the car responding to a call for the elevator or the periphery of the three-sided frame. The sequence of operation state of the elevator includes the position of the lobby corresponding to the car number of the car selected from among a plurality of cars in response to the call for the elevator, the movement of the car of the elevator, the arrival direction of the car, a situation where the car arrives at the calling floor and the door opens, a situation where the door is fully open and starts closing, and a situation where the door is closing. Thus, a user in the lobby can intuitively determine the complicated sequence of operation states of the elevator.

  • Patent number: 11872735
    Abstract: In a first step, a circuit sheet is set such that a first region of a second main surface of the circuit sheet is in contact with a plateau portion of a first mold and a second region is not in contact with the first mold. In the first step, a first fixed portion of the circuit sheet is arranged on a first portion of the first mold, and a second fixed portion is arranged on a second portion of the first mold. The first portion is a portion that is higher than the plateau portion and runs along at least one of a first protruding portion and a second protruding portion provided along the plateau portion. The second portion is a portion where the first protruding portion or the second protruding portion is not provided along the plateau portion.

  • Patent number: 7427378
    Abstract: An analysis method and analysis apparatus involve analysis for a sulfur component using ultraviolet fluorescence capable of removing the interferential influence of NO with good efficiency and certainty to thereby measure a concentration of only sulfur components such as SO2 and others even in continuous measurement over a long term with a high precision. An analysis method involves analysis for a sulfur component using ultraviolet fluorescence. A sample gas is illuminated with ultraviolet and fluorescence is emitted by the ultraviolet illumination and detected to measure concentrations of sulfur components including at least SO2 in the sample gas. NO, which is an interferential component in the sample gas, is oxidized to nitrogen dioxide, followed by the illuminating of the sample gas with ultraviolet.

  • Patent number: 7380476
    Abstract: A gas sampling bag is capable of blowing out the gas uniformly into the bag main body, and filling the bag main body with gas in a securely mixed state. A gas sampling bag that is connected to a constant volume sampling passage, contains a pipe, on which a plurality of gas inlet/outlet holes are formed, in a bag main body, and allows the gas to flow into/out of the bag main body through the gas inlet/outlet holes. The opening of the plurality of gas inlet/outlet holes is formed in such a manner that the size is minimized while the pressure loss is suppressed so as not to increase as far as possible.
