Title: Phase correcting circuit
Inventor: KITAMURA TETSUYA
IPC: H03K5/00
Filed: 1988-04-28
Abstract: PURPOSE:To make the phase difference between a 1st and 2nd clock signals constant by inputting the 1st clock signal and 2nd clock signal having a prescribed phase difference to the 1st clock signal to a NOR gate and inputting its output signal to a flip-flop. CONSTITUTION:A NOR gate 1 receives the 1st synchronizing phase clock signal S1 and the 2nd phase clock signal S2 and an output signal S3 is fed to a data input terminal D of a D FF2. The synchronizing clock signal S1 is inputted to a clock input terminal CK of the D FF2, a signal S3 inputted to the data input terminal D of the D FF2 is latched by the signal S1 and a signal S4 is outputted from an output terminal Q. When a signal S2 whose output delay differs from the signal S1 by a half the period of the synchronizing clock signal is inputted to the NOR gate 1, the same signal S3 is outputted in the same timing the same case as that shown in figure (a). That is, even if a signal S2 without output delay to the signal S1 is inputted, a sufficiently small signal S4 whose output delay is constant with respect to the signal S1 is outputted.

Title: Single mode optical fiber for 1.5mu band
Inventor: MASUDA YUICHI
IPC: C03C13/04
Filed: 1985-05-20
Abstract: PURPOSE:To obtain an optical fiber which evades stress concentration and has a superior transmission band by adding an additive which compensates the difference in coefficient of linear expansion between a core and a clad to the clad together with fluorine. CONSTITUTION:A material to be added to the clad itself is selected to compensate the difference in coefficient of linear expansion between the core and clad, and thus stress concentration on the interface is reduced; and the coefficient of linear expansion of quartz glass to which fluorine is added is smaller than that of pure quartz glass. For the purpose, another additive is added to the clad together with the fluorine to approximate the coefficient of linear expansion to that of the pure quartz glass, reducing the stress concentration. Consequently, the additive which increases the coefficient of linear expansion of the clad is necessary. When the additive has such property that the refractive index is increased, the increase in refractive index is preferably small. In this case, P2O5 approximates the coefficient of linear expansion to that of the pure quartz glass without causing any deterioration in light transmission loss, so P2O5 and fluorine are added as additive to the clad.
