  • Publication number: 20230316723
    Abstract: An information processing apparatus includes: an acceptance unit that accepts processing results of a plurality of processing targets including ground truth processing targets associated with ground truth processing results every time an operator completes processing on part of the processing targets; and a calculation unit that, when processing targets associated with the processing results accepted by the acceptance unit are the ground truth processing targets, calculates an evaluation value indicating an evaluation on the operator based on comparison between the processing results accepted by the acceptance unit and the ground truth processing results.

  • Patent number: 7036527
    Abstract: Disclosed is a composite valve comprising a valve body that is provided integrally with a solenoid valve portion and a differential pressure valve portion. The valve body is formed with an upper valve chest, a lower valve chest, a refrigerant introduction chamber that communicates with the upper valve chest and has a differential pressure valve seat, and a back pressure introduction chamber that communicates with the lower valve chest. A main valve element that is opened and closed by means of the solenoid valve portion is located between the upper valve chest and the lower valve chest. A differential pressure valve element that is opened and closed by means of a differential pressure between the refrigerant introduction chamber and the back pressure introduction chamber is located between these two chambers. The refrigerant introduction chamber, back pressure introduction chamber, and differential pressure valve element are arranged so as not be situated on the outer surface of the valve body.
