    • A series of steps of (A) a step for bringing a cycloalkane into contact with molecular oxygen (oxidizing reactor 2) in the presence of an oxidizing catalyst having an imide unit of the following formula (I): wherein X represents oxygen atom or hydroxyl group; (B) a step for separating the catalyst, and by-produced acid component or a derivative thereof from the reaction mixture (filter 3, extracting column 4, hydrolyzing unit 7, saponifying unit 8); and (C) steps for separating the cycloalkane, a cycloalkanol, and a cycloalkanone from the reaction mixture individually (distilling columns 5, 6, 9, and 10) makes it possible to produce cycloalkanones efficiently. A first component (lower-boiling point component) containing the cycloalkane and a second component (higher-boiling point component) containing the cycloalkanone and cycloalkanol may be separated from the reaction mixture, and the cycloalkanone and the cycloalkanol may be separated from the higher-boiling point component. Such production process is capable of providing cycloalkanones with high efficiency.

    • A connector unit comprises a case, a substrate and a connector. The case is formed with an opening. The substrate is installed within the case and is formed with a signal conductive pattern and a ground conductive pattern. The ground conductive pattern is electrically connected to the case. The connector comprises a contact, an outer conductor and a high impedance member. The outer conductor is electrically connected to the ground conductive pattern. The outer conductor is insulated from the contact but covers, at least in part, the contact. The contact is electrically connected to the signal conductive pattern. The high impedance member has high impedance in a high frequency range. The high impedance member is positioned between the outer conductor and the case within the opening of the case. For example, the high impedance member is an electric wave absorber.
