Title: Modulating system of digital signal
Inventor: ROKUTA MORIHITO
IPC: G11B20/16
Filed: 1984-02-01
Abstract: PURPOSE:To reduce a clock rate less than a 3PM code, to increase the width of a detecting window and to suppress or remove a DC component or a low frequency component by converting an input signal into a code word inserting one or more ''0''s between ''1'' and ''1'' to attain NRZI conversion. CONSTITUTION:An inputted NRZ signal is divided for every M (positive integer) bits and the M bits are converted into a code word consisting of N (M<N-1, positive integer) signal bits; the most significant bit is ''0'' and one or more ''0''s are arranged between ''1'' and ''1''. Out of residual data satisfying said condition, data reducing the absolute value of the accumulated value of weight at the NRZI convertion of data obtained until the current point of time are selected. Only at the time when both the least significant bit of the preceding data and the 2nd bit from the most significant bit of the current data are ''0'', the most significant bit of the current data is made ''1'' and the code word consisting of these bits is NRZI-converted. Thus, the clock rate can be reduced less than the 3PM code, the width of the detecting window can be increased and the DC component or low frequency component can be suppressed or removed.

Abstract: PURPOSE:To prepare an optical fiber glass having low transmission loss even in the far infrared range, and no toxicity and hygroscopicity, by compounding one or more component selected from CaF2, SrF2 and BaF2 with specific amounts of YF3 and AlF3. CONSTITUTION:An optical fiber glass composition composed of (A) 10-64mol% of CaF2, SrF2 and/or BaF2, (B) 0.5-50mol% of YF3 or one or more fluorides of lantanoid elements, and (C) 30-65mol% of AlF3. The sum of (A), (B) and (C) is 100mol%. The addition of YF3 widens the vitrification range, and increases the stability against crystallization. The composition transmits the far infrared light of the wavelength of from 2mum to about 8mum. As the composition is free of the toxic component such as BeF2, ThF2, etc., it has high safety. The absence of deliquescent component in the composition prevents the deterioration of the characteristics by moisture.

Abstract: PURPOSE:To prevent the generation of a dislocation of a relative position rela tion between a mother tape and a copy tape by providing an air reserving groove communicating to an air blow-out port on a tape running direction side from the air blow-out port of the wall surface opposed to a tape running surface of an air guide. CONSTITUTION:A strong pressure by air works on tapes 4-6 extending over a wide area from a transfer part T to a detaching part U. That is to way, the pressure in the transfer part T becomes maximum, and the pressure drops in the tape running direction side or the opposite tape running direction side from said part, but since an air reserving groove 22 is provided, a drop rate of its pressure in the area corresponding to its air reserving groove 22 is extremely low. Also, pressure of 90-98% against the maximum value, in other words, pressure which is scarcely changed from the pressure in the transfer part T can be operated on a transferred part positioned between the transfer part T and the detaching part U of the tapes 4-6. In this way, even if a varia tion is generated in a tension of a copy tape 4 and a mother tape 5, a disloca tion of a relative position relation between the tape 4 and 5 is not generated in its transferred part.
