Title: Preparation of novel nuclease
Inventor: ANDOU TADAHIKO
IPC: C12R1/07
Filed: 1978-10-16
Abstract: PURPOSE: To prepare a nuclease having substrate specificity, which discriminates  the DNA of specific species of organisms, and breaks the phosphodiester bond at a  specific position of the DNA molecule, by separating and purifying an extract of  bacterial cells obtained by the culture of bacteria belonging to Bacillus sphaericus.  
     CONSTITUTION: Endonuclease-producing bacteria belonging to bacillus sphaericus, e.g. Bacillus sphaericus IAM 1286 strain, are cultured in a nutrient medium at 30W37°C using an aerated and agitated fermentor. The cultured cells are collected between the logarithmic growth phase and the initial stage of the stationary phase, disintegrated and extracted to obtain a cell-free extract. The extract is purified by the combination of removal of nucleic acid, ammonium sulfate fractionation, ion exchange chromatography, gel filtration, etc. to obtain the objective endonuclease. The enzyme breaks the phosphodiester bond of Bacillus phage ϕ105C DNA and coil phage λ DNA to DNA fractions having specific lengths.

Filed: 1989-05-19
Abstract: PURPOSE:To obtain the acceleration/deceleration torque by which tension is kept constant by operating the compensation quantity in accordance with different plate width, and correcting a tension reference value at the time of acceleration and deceleration. CONSTITUTION:Plate width is divided by the diameter of a coil, and plate width of D0<D<=D1, D1<D<=D2, and Dn-1<D<=Dn are set as l1, l2, and ln, respectively. These information is set before starting coiling and uncoiling. Subsequently, the outside diameter D of the coil at the time of coiling and uncoiling is measured by a periphery measuring circuit 4. The diameter train D0, D1,... set by a plate width setting circuit 8 and D are compared by a measuring circuit 9, and P for satisfying an expression 1 is determined. Next, by a speed reference arithmetic circuit 6, acceleration alpha is determined. From these information, acceleration/deceleration torque T is derived by an expression 2, and in accordance with the diameter, different acceleration/deceleration torque T can be obtained, and tension can be kept constant.

Title: Address recording system
Inventor: KOYAMA KENICHI
IPC: G11B27/10
Filed: 1980-09-11
Abstract: PURPOSE:To realize the quick and simple searching of address for a disk-shaped recording carrier, by showing the order of music with the 1st address signal and varying the 2nd address signal toward the radius of the recording carrier. CONSTITUTION:The 1st address signal 31 showing the order of music plus the 2nd address signal 32 that gives a monotonous increase from the head of each music are recorded within each information unit. Then sections P3 and P4 are defined as the 3rd music and the 4th music respectively. When the address searching is given to the 4th music, a reproducer performs an arithmetic comparison between the 1st address signal in the reproduced address signal and the address signal desired by a user. A reader is shifted in the radius direction on a disk-shaped recoring carrier until a coincidence is obtained between both above-mentioned address signals and both signals enter the section P4. As a result, the time required for the reader to shift into the section P4 can be reduced enough.
