    摘要： A decoding device that achieves an improvement in code performance by optimization of the quantization width, thus allowing for high-precision decoding of LDPC codes, is provided. A decoding device (3) includes a distribution determining unit (20) that determines a distribution of noise that is superposed on data received by a receiving unit (10), a quantization width determining unit (30) that determines the quantization width that is optimized so that the error probability after decoding becomes the minimum with respect to the noise distribution determined by the distribution determining unit (20) or the noise distribution determined by the distribution determining unit (20) becomes the maximum with respect to a given error probability after decoding, a quantizing unit (40) that quantizes the probability distribution of the received value received by the receiving unit (10) with a predetermined low bit number according to the quantization width determined by the quantization width determining unit (30), and a message determining unit (50) that determines a message as information bits based on the probability distribution of the received value quantized by the quantizing unit (40).

    摘要： In multiplying circuits, filter coefficients are multiplied to tap outputs between the stages of delay circuits, respectively. The multiplication outputs are added by an adding circuit, thereby performing an interpolation arithmetic operation. Phase information and coefficient adjustment data are inputted to a coefficient generating circuit. Either the nearest neighborhood approximating method or the bilinear approximating method can be selected by the coefficient adjustment data, and any of the intermediate characteristics between the nearest neighborhood approximating method and the bilinear approximating method, characteristics which are closer to those of the nearest neighborhood approximating method between the nearest neighborhood approximating method and the bilinear approximating method, and characteristics which are closer to those of the bilinear approximating method can be freely set.

    摘要： A multi-unit switch assembly has a single housing which is divided into a plurality of compartment for respectively accommodating therein a corresponding number of switch mechanisms. Each switch mechanism includes contacts and an actuator rockable within the housing for closing and opening the contacts. Each of the actuators is provided with a spring catch for detachable snap connection with each of operator handles which correspond in number to the number of the switch mechanisms and positioned exteriorly of the housing and thus rockable together with the corresponding actuators for contact closing and opening of the individual switch mechanisms. With the detachable connection of the handle and the actuator in each switch mechanism within the housing, the housing may be mounted to a wall or a like supporting surface prior to assembling the operator handle to the housing. An indicator lamp for showing the switch position is mounted in the housing and transparent portions on the actuator and operator handles permit viewing thereof.

    摘要： A head cleaning device includes a first wiping member, a first drive mechanism, a second wiping member, a second drive mechanism, a common drive source, and control circuitry. The first wiping member wipes a nozzle face of each of a plurality of liquid discharge heads. The first drive mechanism moves the first wiping member to a first wiping position at which the first wiping member wipes the nozzle face and a first retraction position spaced apart from the nozzle face. The second wiping member wipes the nozzle face. The second drive mechanism moves the second wiping member to a second wiping position at which the second wiping member wipes the nozzle face and a second retraction position spaced apart from the nozzle face. The common drive source drives the first drive mechanism and the second drive mechanism. The control circuitry controls the common drive source.

    摘要： A lens driving device includes an auto-focusing driving part that includes an auto-focusing coil and driving magnets, and an optical image stabilization driving part that includes an optical image stabilization coil disposed so as to be spaced apart from the driving magnets in an optical-axis direction and the driving magnets. An autofocus fixing part includes a magnet holder to which the driving magnets are fixed by adhesion, and adhesion surfaces of the magnet holder to which the driving magnets adhere are parallel to the optical-axis direction, and first end portions of the adhesion surfaces facing an optical image stabilization fixing part in the optical-axis direction are opened. Each adhesion surface includes a recessed portion that extends in the optical-axis direction toward a second end portion, which is opposite to the first end portion, from a portion positioned closer to an inside than the first end portion.
