Abstract: Provided are various novel DNA polymerases. Provided are: a DNA polymerase comprising: an amino acid sequence modified from the amino acid sequence of SEQ ID NO: 12, which has a substitution of arginine at position 651 by an amino acid residue having a negatively charged side chain, preferably by asparatic acid or glutamic acid, more preferably by glutamic acid; and a DNA polymerase comprising an amino acid sequence modified from the amino acid sequence of SEQ ID NO: 14, which has a substitution of proline at position 653 by an amino acid residue having a negatively charged side chain, preferably by asparatic acid or glutamic acid, more preferably by glutamic acid.

Abstract: A measurement device and measurement method make it possible to eliminate the load generated by stopping on a measurement subject that is moved among multiple magnetic field generating devices. The measurement device includes a first external magnetic field generating device that generates a magnetic field of a set size, a second external magnetic field generating device that generates a magnetic field of a size that differs from that of the magnetic field of the first external magnetic field generating device, a rotating table that causes the subject of measurement to pass in sequence through the magnetic fields of the first and second external magnetic field generating devices by causing the subject of measurement to move rotationally, and an OMRI measurement processing part and MRI measurement processing part that measures images such as functional images or structural images of the subject of measurement while it is being moved rotationally by the rotating table.

Abstract: When an attenuation pole produces, highly-efficient-izing and a miniaturization of a filter are enabled by changing the electric length between a branch point and each filter. The 1st band pass filter 5 that has the characteristics of center frequency f1, and the 2nd band pass filter 7 that has the characteristics of different center frequency f2 from center frequency f1, In co-planer filter 3 provided with transmission line 9 which connects the 1st band pass filter 5 and the 2nd band pass filter 7, and branch point 11 formed in transmission line 9. It is designed so that an attenuation pole may produce in either [at least] the 1st band pass filter 5 or the 2nd band pass filter 7, and the frequency region which the formation position of branch point 11 is adjusted and an attenuation pole produces is adjusted.
