Abstract: A transformer apparatus includes: a case with a component mounting surface; an external-terminal provided on a wall adjacent to the component mounting surface of the case; a transformer provided on the component mounting surface and including a magnetic core and a winding; and a support provided in a position between the external-terminal and the core on the component mounting surface, and including a first-slit in a top surface of the support, the first-slit holding a first-conductor of the winding drawn from the core and a second-conductor drawn from the external-terminal, wherein the first-conductor is held at one end of the first-slit by a conductive member, the second-conductor is held at the other end of the first-slit by the conductive member, the first-conductor and the second-conductor are electrically connected through the conductive member, and the first-conductor and the second-conductor have surplus lengths.

Abstract: At a base station, a table is prepared that for each index value among multiple different index values, associates repetition counts of different channels correlated with each other. The base station acquires reception information indicating a reception state of a wireless signal at a mobile station, determines a repetition count for each channel based on the reception information, and acquires from the table, an index value corresponding to the respective repetition counts for the channels. The base station transmits to the mobile station, a wireless signal that includes the index value to notify the mobile station of the index value. The mobile station has a table that for each index value among different index values, associates repetition counts of different channels correlated with each other and acquires the repetition counts of the channels from the table, based on the index value from the base station.

Abstract: The power level of a wavelength division multiplexed optical signal is detected by a detection unit. When the power level of the optical signal detected by the detection unit is equal to or lower than a first threshold, the coupling direction of an attenuation unit for controlling the coupling direction for the ports of the optical signal is controlled in the direction orthogonal to the array direction of the ports. When the power level of the optical signal exceeds a second threshold, the coupling direction of the attenuation unit is controlled in the array direction of the ports.

Abstract: A method of manufacturing a semiconductor device has a first exposure to the photoresist by using a first mask having a first portion of a monitor pattern, a second exposure to the photoresist by using a second mask having a second portion of the monitor pattern so that a first image of the first portion and a second image of the second portion are connected.
