The voltage smoothing circuit includes first and second smoothing capacitors, a first balancing resistor, and a second conduction regulating portion. The first smoothing capacitor and the second smoothing capacitor are connected in series to each other and are connected in parallel to the power supply portion. The first balancing resistor is connected in parallel to the first smoothing capacitor. The second conduction regulating portion is connected on a current path in parallel with the second smoothing capacitor and conducts current in one direction on the current path in a case where a voltage equal to or greater than a second predetermined voltage has been applied.

摘要: A fan control system includes a first fan, a second fan adjacent to the first fan, a first motor that rotates the first fan, a second motor that rotates the second fan, and a control unit. The control unit controls the rotational speeds of the first motor and the second motor. The control unit decreases the rotational speed of the first motor and increases/decreases the rotational speed of the second motor when the rotational speed of the first motor must be decreased. The control unit can decrease the rotational speed of the second motor when the rotational speed of the first motor whose rotational speed has been decreased is lower than a prescribed rotational speed, and increase the rotational speed of the second motor when the rotational speed of the first motor whose rotational speed has been decreased is higher than the prescribed rotational speed.

摘要: An imaging system may include an image sensor array and column randomizing multiplexers. The imaging system may include a data output circuit and image readout circuitry such as analog amplifiers, analog-to-digital converters, and memory circuits. The column randomizing multiplexers may include a first column randomizing multiplexer between the image sensor array and at least some of the image readout circuitry. The first column randomizing multiplexer may randomly connect columns of the image sensor array to the image readout circuitry. The connections made by the first column randomizing multiplexer may be randomized as each row of the image sensor array is read out. The column randomizing multiplexers may include a second column randomizing multiplexer between at least some of the image readout circuitry and the data output circuit. The second column randomizing multiplexer may reorder image data for the image readout circuitry.

摘要: A large liquid crystal display (100) comprises a light guide plate (3) arranged on the back side of a liquid crystal panel (1). The front surface of the light guide plate (3) is flat, while the back surface thereof is concave. The upper and lower end faces of the light guide plate (3) respectively facing hot cathode fluorescent lamps (2a, 2b) have a convex shape projecting toward the respective lamps. White light from the fluorescent lamps is incident on the upper and lower end faces of the light guide plate directly or by being reflected by reflectors (4a, 4b), and propagates within the light guide plate while being reflected by the front and back surfaces of the light guide plate. At the front surface of the light guide plate, a part of the white light is directed toward the back side of the liquid crystal panel (1) by a light guide portion (5).

摘要: A motor drive control device for controlling the driving of a brushless motor includes position detecting units (e.g. sensors or Hall elements), a drive signal determining unit and a drive signal outputting unit (an output circuit). The position detecting units are disposed in positions apart from each other by an electric angle of 120 degrees and output position detection signals representing the position of the rotor with respect to the stator. The drive signal determining unit determines drive signals for driving the 3-phase drive coils on the basis of the position detection signals. The drive signal outputting unit generates and outputs, to the 3-phase drive coils, the drive signals that have been determined by the drive signal determining unit.
