Abstract: A filtering medium includes a nonwoven fabric and a first electrode having an input terminal of power. The first electrode is provided on a surface of the nonwoven fabric. Alternatively, in a case where the nonwoven fabric has a plurality of fiber layers, the first electrode may be provided between the fiber layers. An air purifier includes the filtering medium disposed between a sucker and a discharger of a gas, and an output terminal via which power is output to the first electrode of the filtering medium.

Abstract: A computer, which is communicably connected to a plurality of computers having respective storage areas for storing data and in which second data that is replication of first data arranged in a storage area of own computer is arranged in storage areas of other computers, and the computer holds capacities of the storage areas of the respective computers and determines first data ranges for arranging the first data in the storage areas of the own computer and the plurality of other computers in accordance with the capacities, determines a second data range that is a largest data range or has a largest capacity, with, as a starting point, a data range that is different from a largest data range or a data range having a largest capacity in the first data ranges, and arranges the data in the storage areas of the respective computers.

Abstract: By a display unit of a vehicle control device, a lane line which partitions a driving lane and a neighboring lane is displayed on a display screen in a perspective from a host vehicle to the front of the host vehicle and the lane line is displayed while the position of the lane line is changed according to a progress situation of a lane change. For this reason, a movement of the lane line in a display of the display screen and a movement of the lane line at the point of view of a driver of the host vehicle become more similar. Therefore, the driver of the host vehicle has a reduced uncomfortable feeling with the display of the display screen, and thus it becomes easier for the driver of the host vehicle to grasp the progress situation of the lane change.

Abstract: A receiver according to the present invention includes a first receiving (RCV) quality detector and a second RCV quality detector connected before a combining unit. The second RCV quality detector determines a quality of a signal output from at least one of a first receiving unit and a second receiving unit by a method different from that of the first RCV quality detector. A controller allows the receiver to operate in a single receiving mode when a determination result of the second RCV quality detector is not better than a predetermined level regardless of a determination result of a determination result of the first RCV quality detector not being a predetermined level. When the receiver passes in an area where the receiver cannot receive a broadcast signal, the determination result of the second RCV quality detector is not better than the predetermined level. In response, the controller allows the receiver to operate in the single receiving mode, thereby reducing power consumption of the receiver.

Abstract: Provided is a reception device that selectively receives an analog broadcast signal and a digital broadcast signal. The reception device includes: an oscillation unit operable to output an oscillator signal; a frequency conversion unit operable to output an IF (Intermediate Frequency) signal group based on the oscillator signal outputted from the oscillation unit and a reception signal; a filter unit connected to an output side of the frequency conversion unit; and a control unit operable to control a frequency of the oscillator signal outputted from the oscillation unit. The control unit controls: the frequency of the oscillator signal to be within a reception frequency band when receiving the digital broadcast signal; and the frequency of the oscillator signal to be outside the reception frequency band when receiving the analog broadcast signal. With this configuration, it is possible to improve reception quality when receiving an analog broadcast signal.

Abstract: An antenna device includes a grounding subject, a feeder insulated from the grounding subject, a first conductor shaping like substantially a looped triangle and coupled to the feeder at a first feeder top, and a second conductor symmetric to the first conductor with respect to a phantom line extending through the feeder and coupled to the feeder at a second feeder top. The first feeder top is placed closest to the grounding subject among other elements of the first conductor, and the second feeder top is placed closest to the grounding subject among other elements of the second conductor. The foregoing structure allows a high electrical field section of a first side of the first conductor and that of a first side of the second conductor to leave further away from the grounding subject.
