Abstract: An object of the present invention is to provide a control device and control method that make it possible to perform an inter-device authentication process more certainly and improve security. Provided is a control device including: a control section configured to control an authentication process of performing a process related to device authentication together with at least one communication device on a basis of information included in a signal received through wireless communication with the communication device. The control section performs control in such a manner that authentication information is changed for each process group in which the authentication process is repeated more than once, the authentication information being information to be used for the authentication process.

Abstract: A control device comprising, a control section configured to control an authentication process of performing a process related to device authentication together with at least one communication device on a basis of information included in a signal received through wireless communication with the communication device, wherein the control section performs control in such a manner that a signal including authentication information that is information to be used for the authentication process is transmitted to the communication device through the wireless communication, the authentication information varying depending on signal types, which are types of roles of signals to be transmitted to the communication device in the authentication process.

Abstract: [Problem] To provide a so-called competitive immunological assay method capable of more uniformly immobilizing on a solid phase a substance equivalent to an antigen. [Solution] This immunological assay method measures an analyte substance in a sample by using: an equivalent substance immobilized on the solid phase during the execution of the assay, the equivalent substance being immunologically equivalent to the analyte substance; and a labeled antibody for specifically binding to the substance equivalent to the analyte substance. The assay method is characterized in that the equivalent substance is immobilized on the solid phase using: a bond between the equivalent substance and a carrier substance, the carrier substance being a substance to which the labeled antibody does not bind; and a bond between the carrier substance and a specific binding substance immobilized on the solid phase, the specific binding substance being a substance that binds specifically to the carrier substance.

Abstract: Provided is an air conditioner which comprises multiple outdoor units, the air conditioner being configured so that, with the use of a low cost configuration, required refrigeration machine oil is supplied to all the outdoor units through refrigerant piping and so that the air conditioner has increased reliability. An air conditioner is provided with multiple indoor units and with four outdoor units which are connected to the multiple indoor units through refrigerant piping. A line of first refrigerant piping leading from the multiple indoor units is branched into two lines of second refrigerant piping, each of the two lines of second refrigerant piping is branched into two lines of third refrigerant piping, and the four lines of third refrigerant piping are respectively connected to the four outdoor units.
