摘要： PROBLEM TO BE SOLVED: To eliminate the situations of the case of correcting an error to a non-expanded component and to an expanded component when an expanded Reed-Solomon code is decoded, and of the case of achieving a plurality of times of Euclid's algorithm operational process and a plurality of times of chain search process when a mistake of estimation of the number of pieces of the error is made. SOLUTION: The estimated number of pieces of the error EN1 estimated at an estimation portion 60 of the number of pieces of the error from an input data syndrome SI is compared with the calculated number of pieces of the error EN2 calculated at a calculation portion 70 of the number of pieces of the error in a decoding process. After an error correction process is applied at an error correcting portion 40 based on the comparison data and the input data syndrome SI, a correction data syndrome is calculated by calculating the syndrome again to an error-corrected data C1 at a syndrome calculating portion 10. An input data D1 is output as a second corrected data C2 when the error correction is conducted or when the estimated number of pieces of error EN1 is different from the calculated number of pieces of the error EN2.

摘要： PROBLEM TO BE SOLVED: To provide an error correction circuit and an error correction method, that can use a trellis decoder in n kinds of states, that is, a trellis decoder capable of conducting decoding in a plurality of different kinds of states, so as to decode data without producing coset.
SOLUTION: A branch metric production circuit 201 generates each branch metric, with respect to each code data. An ACS circuit 202 sums each range metric and a path metric in each state, compares the sums, and selects the smallest sum for a new path metric in each state and stores data, corresponding to the selected path in each state to a path memory. A trace back processing circuit 204 traces back a predetermined cut-off path length along a surviving path, which contains a state whose new path metric is smallest, so as to determine data Y
2 Y
1 (4-states) or data X
2 X
1 (8-states). Using the configuration above, decoder can decode data using one 4-state and 8-state which are common use trellis.

摘要： PROBLEM TO BE SOLVED: To provide a high acoustic pressure even in a low voltage by constituting a circuit so as to apply the output of a rectangular wave oscillating means on one end of the sounding body and the output of an inverting means on the other end. SOLUTION: In an oscillating circuit 2 comprising an inverter IC as a rectangular wave oscillating means, a rectangular wave is generated in the turning off state of a switch 1, its output is applied on the terminal 3-1 of a sounding body 3, the phase is inverted by an inverter circuit 4 composed of an inverter IC as an inverting means and is applied on the terminal 3-2 of the sounding body 3. In this case, the phases of the respective terminals of the sounding body 3 are reverse phases to each other and the state HIGH and LOW is repeated, the applied voltage becomes a voltage being added by the output voltage of the oscillating circut 4 and the output voltage of the inverter circuit 4 and almost twice of a power source voltage generally in the case of a high impedance load such as a piezoelectric buzzer. Consequently, since a twice voltage of the output of the oscillating circuit 2 is applicable on the sounding body 3, high acoustic pressure is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a controller for a gas cooker in which even with any failure erroneous judgement of a combustion state is eliminated, and a switch operation is recognized on a safety side for ensurance of safety. SOLUTION: AC voltage of an AC power supply 1 is applied to a flame rod 2 for sensing a flame and is opened and closed with a phototriac 10. Upon combustion a pulse shaped flame rod current 7 flows through the flame rod 2 via a flame which is converted to a pulse shape combustion detection voltage signal 8 with a field effect transistor 3 and is inputted into a microcomputer 6. The combustion detection voltage signal 8 and the waveform of a switching pulse 9 for driving the triac 10 are compared, and if they are same phase, then it is judged that the state is a combustion state while if 0 volt level, then it is judged the state is a non-combustion state. In this case, when the field effect transistor 8 is opened and troubled after the detection of combustion, voltage of a drain 4 becomes a constant level of DC 5V so that the failure can be judged for discrimination of the combustion state and the trouble state.
