Title: Digital signal recording device and record reproducer
Inventor: OBATA SHINICHI
IPC: G11B19/02
Filed: 1993-05-27
Abstract: PURPOSE:To enable dubbing at a high speed, and to shorten the dubbing time by installing the changeover circuit of compressed data on the recording side and expanded data on the reproduction side and transmitting reproduction side data to the recording side without expansion at the time of dubbing at a high speed. CONSTITUTION:A mean read-out rate is increased by a medium access requirement signal 57 from a first micro-computer 7 and continuous read is conducted at the time of a dubbing mode at a high speed in a mode changeover signal 22 from a mode setting terminal 21. The transfer rate of the input 5 of a first buffer RAM 6 and the transfer rate of an output 9 are equalized by a RAM control signal 8. A signal 9 before expansion output from the RAM 6 is selected as an output signal 24 in a changeover circuit 23, and a mean write rate to a recording-side recording medium 28 is also increased by the signal 57 and continuous wite is performed. Consequently, the signal is reproduced at a high speed from a reproduction-side recording medium 1, and the regenerative signal is recorded on the medium 28 at a high speed. Accordingly, compressed data can be dubbed without expansion, thus accelerating the dubbing.

Abstract: PURPOSE: To phenol resin improved in punchability without detriment to its flame retardancy, prepared by reacting a mixture of a phenol, an aldehyde and a basic catalyst with diethyl N,N-bis-(2-hydroxyethyl)aminomethylphosphonate.  
     CONSTITUTION: To a phenol such as phenol or cresol is added an aldehyde such as formalin or paraformaldehyde. The pH of the mixture is adjuted by addition of a basic catalyst such as sodium hydroxide or an amine. To the mixture is further added diethyl N,N-bis(2-hydroxyethyl)aminoethylphosphonate and the resulting mixture is reacted. The amount of diethyl N,N-bis(2-hydroxyethyl)aminomethylphosphonate is pref. such that 13W30pts.wt. of diethyl N,N-bis(2-hydroxyethyl)aminomethylphosphonate is used per mol of phenols. When said amount is below 13pts.wt., punchability-improving effect is little, and when said amount exceeds 30pts.wt. the heat resistance and electrical insulation resistance are lowered.

Abstract: PURPOSE:To obtain stable analysis results by separating phosphoric acid ions and fluoride ions from each other in an excellent state by using an aqueous solution containing carboxylic acid and a specific quantity or more of boric acid and having a pH value lower than a fixed value as an eluate (acidic). CONSTITUTION:Carboxylic acid having a dissociation constant of <=6.5 is used as that to be contained in the eluate used for the title method. Since a remarkable effect can be obtained when boric acid which is an important constituent for accelerating the separation of fluoride ions from phosphoric acid ions is contained in the eluate by about >=10mM, boric acid is added to the eluate in the form of boric acid (H3BO3) or boric anhydride (B2O3). Then, after separating anions by making an aqueous solution containing carboxylic acid and >=10Mm of boric acid and having a pH value of <=6.5 to flow to an anion exchange column as an eluate together with a sample, the anions are detected. The chromatogram obtained by this analyzing method shows that the peak 1 of phosphoric acid ions and the peak 2 of fluoride ions are excellently separated from each other.
