A decoding device compares the number of errors estimated from input data syndromes by an error number estimation section with the number of errors computed by an error number computation section during decoding process, performs error correction by an error correction section based on this comparison result and the input data syndromes, performs a syndrome computation for error corrected data by a syndrome computation section again to obtain corrected data syndromes, and outputs input data as second corrected data when erroneous correction is performed or the estimated number of errors differs from the computed number of errors.

The present invention provides an error correction circuit for receiving and decoding a trellis-encoded signal of a series of data Z , Z , . . . ,Z which comprises convolutional-encoded bits and unencoded bits, the convolutional-encoded bits being obtained by convolutional-encoding lower t bits X , X , . . . ,X of an input p-bit series of data X , X , . . . , X (where p&gE;2, q&gE;p, and p>t&gE;1), and the unencoded bits being obtained by not convolutional-encoding upper (p-t) bits thereof. The circuit includes: a maximum likelihood decoder for preselecting one of m parallel paths of transition from state x at time k to state y at time k&plus;1.

Error correction circuit and error correction method

Gas flow control apparatus that includes a gas flow control unit having a gas flow adjusting capability and a gas closing capability of selectively opening and closing a gas. A stepping motor is used for driving the gas flow control unit. A drive control unit is provided for controlling the stepping motor. The gas flow control unit is capable of adjusting the gas flow in multiple stages by selectively opening and closing one of a plurality of gas flow adjusting holes and also capable of varying the gas flow in multiple stages by selectively opening and closing one of the plural gas flow adjusting holes according to a number of pulses of the stepping motor.

A method for manufacturing a solid-state imaging device includes forming a transfer channel portion and a light-receiving portion in a silicon substrate; forming a silicon oxide film on the silicon substrate; forming a silicon nitride film on the silicon oxide film, the silicon nitride film acting as a gate insulating film together with the silicon oxide film above the transfer channel portion and acting as an anti-reflection film above the light-receiving portion; forming a protection film on the silicon nitride film; forming a polysilicon film above the silicon nitride film via the protection film at least above the light-receiving portion; and etching the polysilicon film so as to form a transfer electrode above the transfer channel portion. The etching of the polysilicon film is carried out so that the polysilicon film is removed above the light-receiving portion while the protection portion remains.

A safety device for a heating apparatus detects the errors of the input power-supply voltage, failures of the respective heating device and control device, and displays the detected failure and safety stops the associated apparatus. The safety device quickly and safely stops only a faulty heating function if the heating apparatus further has a plurality of heating functions, and allows the other normal heating functions of the heating apparatus to be used.
