A radio base station apparatus provided with an array antenna having a plurality of antenna elements for calibrating a phase difference among the array antenna elements. The base station has a probe signal adding unit which divides one probe signal and adds the divided probe signals to each receive signals received by the plurality of antenna elements. A probe data extracting unit extracts the probe data from the receive signals added with the probe signal. A phase calibration calculation unit calculates correlating phase calibration values required for calibrating a phase of each receive signal based on the probe data extracted by the probe signal extracting unit. A phase calibration unit calibrates a phase difference among the array antenna elements by calibrating the phase of the each receive signal based on the phase calibration from the phase calibration calculation unit.

An electric-field control electrode (5) is formed between a gate electrode (2) and a drain electrode (3). A multilayered film including a SiN film (21) and a SiO2 film (22) is formed below the electric-field control electrode (5). The SiN film (21) is formed so that a surface of an AlGaN electron supply layer (13) is covered with the SiN film (21).

An image forming system or the like may be installed at a public location such as a computer center of university to serve people who want to print for various purposes. Restrictions may be placed on the use of the system. Restriction on the use of the system may be lifted temporarily depending on the circumstances. For example, when a user is desperate to print a document despite the fact that the user is under restriction, the restriction may be lifted temporarily with some conditions. A printing system includes a cancellation requesting section and a printing section. The cancellation requesting section issues a request for cancellation of a print restriction placed on a user. The printing section cancels the print restriction in response to the request.

A seatbelt reminder system warns a crew member when the crew member has not fastened a seatbelt. The system makes a way of giving a reminder different between a case (S302, S303, or S304) where the running state of a vehicle is detected when the unfastened state of the seatbelt is detected and a case (S310, S311, or S312) where the unfastened state of the seatbelt is detected when the running state of the vehicle is detected.
