Title: Production of magnetic recording medium
Inventor: SAKURAI KAZUE
IPC: G11B5/845
Filed: 1986-07-29
Abstract: PURPOSE:To easily form circumferentially orientate disk-like magnetic recording media with high mass-productivity by using a pair of rod-like magnets having specific size relating to that of each disk-like magnetic recording medium. CONSTITUTION:A pair of orientation magnets 1 are oppositely arranged on the center of an original plate sheet 2 coated with a magnetic coating material and unhardened so as to hold the sheet 2 between both the magnets 1 and the sheet 2 is passed in the longitudinal direction (arrow 3 direction) of the magnets 1 while keeping the sheet 3 on the approximately center position of a gap (g) between the sheets 2 to orientate needle-like magnetic substances in the magnetic coating material. In case of traveling the sheet 2 in the arrow 3 direction, orientation patterns shown by arrows are formed on a magnetic layer of the sheet 2. The sheet 2 orientated by said procedure is punched like a disk with a prescribed diameter as shown by a broken line circle. At that time, the sheet 2 is positioned so that a straight line (shown by a straight broken line) passed by the centers of orientation magnets and the center point of the edge of the sheet 2 is set up on the center of the disk and then punched. Consequently, the disk-like magnetic recording medium having the circumferentially orientated magnetic layer can be obtained.

IPC: C07D209/44
Filed: 1994-07-28
Abstract: PURPOSE:To obtain a 1,3-diiminoisoindoline derivative under mild conditions with no loss by adding ammonia and potassium hydroxide to an alcoholic dispersion of a 1,3-diiminoisoindoline derivative nitrate followed by removing both the ammonia and resultant potassium nitrate and then removing the alcohol. CONSTITUTION:The nitrate of a 1,3-diiminoisoindoline derivative of formula I (R is a 1-10C alkyl, alkoxyl, alkylthio or OH; (n) is 04) is first dispersed in an alcohol. Second, ammonia is blown into the dispersion into a homogeneous solution, which is then incorporated with potassium hydroxide (in an equimolar amount to the nitrate). Third, the ammonia in the solution is removed to effect deposition of potassium nitrate which is then filtered off. Finally, the alcohol is removed from the alcoholic filtrate to obtain the objective 1,3- diiminoisoindoline derivative of formula II. The nitrate of this derivative is obtained by reaction of the corresponding phthalic anhydride derivative with both urea and ammonium nitrate in the presence of a molybdic acid catalyst.

Filed: 1988-07-14
Abstract: PURPOSE:To always execute stable operation by providing a level converting circuit, amplifying an input signal level with prescribed amplification factor and automatically executing the control of a receiving gain to correspond to a line. CONSTITUTION:A signal inputted from lines L1 and L2 is passed through a transformer 1, converted to a digital signal by a level detector 6 and inputted to a control circuit 8. The circuit 8 sends a signal to show the amplification factor to an amplifier 7 in correspondence to the input signal from the detector 6. The amplifier 7 amplifies an inputted analog signal by the signal from the circuit 8 and sends the analog signal to a MODEM 3. The analog signal is demodulated by the MODEM 3 and converted to the digital signal. Signal processing is executed to this digital signal in a receiving part 4 and the signal is returned to a picture signal. Since the circuit 8 suitably controls the input signal to the MODEM 3 and executes the control to a MODEM speed which corresponds to the signal level, the stable operation is always executed and the picture of satisfactory quality can be obtained.
