Abstract: Memory (237) stores relative correction values that indicate the differences of transfer characteristics between a) a radio unit made up of transmission circuit (211) and reception circuit (212), and b) a radio unit made up of transmission circuit (221) and reception circuit (222). Correction control unit (239), by means of phase shifter (240) and amplifier (241), uses the relative correction values to correct transmission signals. In similar fashion, the adaptive array apparatus and the radio base station perform corrections in order that identical array antenna patterns are formed at times of reception and transmission.

Abstract: A current flowing through a reactor flows through a resistor, which generates a voltage in accordance with the value of the current. As the voltage generated by the resistor is greater than or equal to the threshold of a transistor, the transistor is in an on state. As the current flowing through the reactor decreases and the voltage generated by the resistor becomes lower than the threshold of the transistor, the transistor turns off and an NMOS turns on. Accordingly, the gate voltage of an NMOS is decreased by a diode, ensuring that the NMOS is turned off before the current flowing through the secondary winding of a transformer becomes zero.

Abstract: A transformer has a primary winding connected to a pair of DC input terminals via an active switch, and a secondary winding connected to a pair of DC output terminals via a first rectifying and smoothing circuit. The active switch is driven constantly under normal load, and at intervals under light load, under the direction of a switch control circuit. This switch control circuit is powered with a control voltage fed from a second rectifying and smoothing circuit which is connected to a tertiary winding of the transformer. In order to preclude malfunctioning or nonoperation in the event of an abnormal drop of the control voltage during operation in light load mode, the switch control circuit is equipped to drive the active switch at shorter intervals in control voltage recovery mode when the control voltage falls below a predefined limit than the normal intervals of the light load mode.

Abstract: An ion wind generator (20) is arranged on one side of a light source (1). The ion wind generator (20) produces an air current by negatively ionizing air by corona discharges at a needle electrode (21), or negative side, and drawing the negatively-ionized air at a cylindrical electrode (22), or positive side. The air current blows toward the light source (1) and removes heat generated by the light source (1). An ultraviolet ray from the light source (1) is introduced to a vent of the ion wind generator (20) by a first dichroic mirror (4) and a ultraviolet ray reflection mirror (17). Though air exhausted from the vent includes ozone (o3) produced by corona discharges, the ozone is decomposed by the ultraviolet ray.

Abstract: A pressure sensor portion includes a plurality of pressure sensors arranged in a plurality of rows and a plurality of columns inside a pressure-sensor-equipped carpet. The pressure sensor portion senses a pressure applied to the surface thereof and outputs a pressure value to a control portion. In an initial learning mode, a storage portion stores, as an initial value, the pressure value output from the pressure sensor portion. In a sensing operation mode, the control portion outputs to a modem portion a data signal indicating that an abnormal event is sensed, when the pressure value output from the pressure sensor portion is larger than the initial value stored in the storage portion by at least a prescribed threshold value. The modem portion superimposes the data signal received from the control portion on a power carrier wave (with a frequency of 50-60 Hz) and outputs the data signal to a power supply plug.

Abstract: A partition 13a is provided at the almost center of a parallel sheet feed tray 13 in a main-scanning direction and recording paper sheets P1 and P2 such as postcards are mounted in two rows in parallel in the main-scanning direction. By bringing upper surfaces of the recording paper sheets P1 and P2 into contact with a pick roller 5, the recording paper sheets P1 and P2 are picked one by one per row and fed toward an inside of a housing 10. While the recording paper sheets P1 and P2 are conveyed in a sub-scanning direction with being arranged in parallel in the main-scanning direction, ink drops are discharged to both the recording paper sheets P1 and P2 with reciprocation of a carriage 2 with the ink cartridges 3 in the main-scanning direction. Thus, images are formed on the two recording paper sheets P1 and P2 simultaneously, and thereby shortening time necessary for printing a lot of recording paper sheets.
