To provide a microorganism with enhanced secretory production of a protein or polypeptide and a method of producing the protein or polypeptide using the microorganism. A modified microorganism that has been genetically modified to delete 60 to 80 carboxyl-terminal amino acids of SecA.

Modified microorganism

A signal processing device and a signal processing method are provided which can reproduce a smooth signal in the reproduction of a discrete signal having a non-uniform sample point interval. The device includes a coefficient calculation unitthat inputs a sample point signal Erepresentative of the time of a sample point of a discrete signal Ehaving a non-uniform sample point interval to obtain a coefficient of a sampling function corresponding to the discrete signal, and a reproduction signal calculation unitthat obtains a continuous reproduction signal Eby calculating and outputting a function value within the sample point interval from the discrete signal and the value of the coefficient outputted by the coefficient calculation unit.

Discrete signal processing device and processing method

A signal processing device which outputs a discrete signal composed of a string of the sampling values and parameters m signal. The signal processing device includes a sampling circuit which samples an input signal and outputs a discrete signal, multiple function generators which generate multiple sampling functions with parameters m different from each other, plural inner product operating units for each of parameters m that take an inner product between the input signal and each of plural sampling functions and output an inner product operating value, and a judging unit which determines parameter m providing a minimum error out of multiple errors composed of differences between the sampling value and inner product operating values output from the multiple inner product operating units and outputs the parameters m signal.
