摘要:
An object to be decontaminated contaminated with radioactive material is introduced into an acid eluting solvent to dissolve the radioactive material. The radioactive material dissolved is concentrated and separated from the eluting solvent in the present method. The object to be decontaminated comprises contaminated soil and contaminated liquid. One or both of the contaminated soil and the contaminated liquid are collected and introduced into the eluting solvent. The radioactive materials and the object to be decontaminated dissolved in the eluting solvent are separated into solid and liquid. The decontaminated soil separated from the eluting solvent is collected. The eluting solvent used for separating the radioactive material and in which radioactive material is dissolved is concentrated.

An error correction method and device and a communication system using them, including an LDPC code generation method capable of adjusting an encoding rate of an LDPC code in a variable manner while leaving the length of the code constant by use of an efficient encoding method or mechanism supporting a variable encoding rate, so that the encoding rate of the LDPC code can be adjusted without changing the code length. An error correction method includes a row dividing to divide each of a part or all of rows into two or more rows based on one parity check matrix, and a code construction to construct a plurality of LDPC codes with arbitrary code rates, respectively.

A driving device is provided and includes: an actuator that includes a driving shaft attached to a piezoelectric element; and a driving signal control unit. The piezoelectric element is expanded and contracted in response to a driving signal. The driving shaft is reciprocated by the expansion and contraction operation of the piezoelectric element to move a driven member that is frictionally engaged with the driving shaft. The driving signal control unit outputs to the piezoelectric element a second driving signal that increases a driving force applied to the driven member and reduces the movement speed of the driven member during a period from the start of the expansion and contraction operation of the piezoelectric element to a predetermined time, as compared to a first driving signal output when the driven member is moved after the period has elapsed.

A mobile device includes a camera module and a magnetism generating part that is different from the camera module. The camera module includes: a movable portion that corrects camera shake; a magnetism detecting element that detects a position of the movable portion. when the camera module is in a photographing state, the magnetism generating part is arranged at a position distant from the magnetism detecting element by at least the distance of D mm or more, where D = magnetic force of the magnetism generating part [ gauss ] .

An error correction coding apparatus includes a first coding unit for coding a sequence data to be coded which includes information source data for each frame to generate an error correcting code word sequence including a parity sequences, and a first rearranging unit for rearranging elements of the error correcting code word sequences of a plurality of frames generated by the first coding unit. The first rearranging unit rearranges elements of the parity sequences included in the error correcting code word sequences. The first rearranging unit also rearranges elements of the error correcting code word sequences other than the parity sequences, within the error correcting code word sequences other than the parity sequences.

An apparatus for treating the surface of an object to be treated comprising introducing a surface treatment fluid into a reaction vessel (4) capable of receiving an object, introducing the surface treatment fluid into a separation vessel (14) after the object is subjected to surface treatment, and circulating the surface treatment fluid, from which a contaminant has already been removed, to the reaction vessel (4). At the time of treatment on the surface of the object, a circulation passage for the surface treatment fluid including the reaction vessel (4) is communicated and the surface treatment fluid is constantly circulated through the circulation passage.

When an error correction decoding unit 26 of a data reception device 2 fails in error correction decoding of a codeword, an MIMO processing unit 15 of a data transmission device 1 deforms transmitted codewords according to a predetermined rule, and transmits the codewords, and the error correction decoding unit 26 of the data reception device 2 reproduces data by using the deformed codewords. As a result, not only the noise but the interference wave components can be reduced, and the success rates of the demodulation and error correction decoding can be improved greatly.

Disclosed is a driving device capable of stably operating a plurality of actuators.Control units supply driving signals to piezoelectric elements to control actuators such that the actuators repeatedly change their operational states between a driving state and a stop state. In addition, the control units control the actuators to enter the stop state at different timings. As such, since the actuators enter the stop state at different timings, it is possible to reduce or prevent the situation that all of the actuators stop at the same time by shifting the use timing of a power supply circuit. In addition, it is possible to reduce or prevent the situation that all of the actuators are driven at the same time and a current is supplied to all the actuators at the same time.
