Abstract: PURPOSE:To provide a novel DNA having a specific base sequence and autonomous replicating ability and capable of efficiently producing an useful peptide, protein, etc. CONSTITUTION:Autonomous replicating sequence DNA of the mammal cell has a base sequence expressed by the formula. The DNA is produced by the following method: DNA is taken out from a mammal cell and treated with a proper restriction enzyme to give a DNA fragment having proper size, which is then blended with DNA linking protein to afford a DNA-protein linked product. The aimed DNA can be obtained from the DNA-protein linked product by applying ordinary protein separating and obtaining means such as antigenantibody reaction. Gene product can be produced using selfrenewal ability of the resultant DNA sequence in a cultured cell or by a genetic animal and production of a plasmid containing the DNA, mammal cell transformed with the above-mentioned plasmid and gene product obtained by using the transformed cell are useful.

Abstract: PURPOSE:To ensure all lead terminals to be in contact with a printed circuit board by applying bending processing to a frame and a tie bar prolonged from a same side of an opening so as to be escaped against the thickness of a frame laminated and arranged precedingly. CONSTITUTION:This ladder type filter 1 consists of a case 2,a filter member 3 in which piezoelectric resonators 6,8 and terminal boards 5,7,9 are laminated, and a seal member sealing the case 2.

SOLUTION: When DC power is switched by a plurality of transistors of an inverter section 3 and is supplied to a brushless motor 4, a position detecting circuit 10 synthesizes the terminal voltages of armature windings by means of a synthesis circuit 10a and then cuts a DC component of the synthesized voltage (neutral point voltage: induced voltage waveform) by means of a DC-cutting circuit 10b and at the same time, generates a specified reference voltage by means of a voltage generating circuit 10c and connects the neutral voltage with its DC component cut and the specified reference voltage with a resistor circuit 10e and fluctuates the neutral voltage above and below the specified reference voltage.  The neutral voltage which has been fluctuated above and below is compared with the specified reference voltage, by a comparing circuit 10e to detect a signal at the intersection between the neutral voltage and the reference voltage (a signal which changes at the half point of the induced voltage) and then outputs the signal to a controlling circuit 11. The controlling circuit 11 detects a magnetic pole changing point of a rotor changes (in other words, detects the position of the rotor) from the signal which changes at the half point of the induced voltage (in other words, detects the position of the rotor) and then switches the energization of the armature windings according to the magnetic pole changing point.
