Title: Substrate for photographic paper
Inventor: KITAGAWA KEIJI
IPC: D21H27/30
Filed: 1981-12-03
Abstract: PURPOSE:To prevent the contamination of cut surfaces by using specific high density PE for PE-coated photographic paper. CONSTITUTION:A coating layer is formed of high density PE of 0.85-1.30dlg intrinsic viscosity (value measured at 135 deg.C in decalin) and >=0.940g/cm<3> density contg. >=7 methyl groups in 1,000 carbon atoms on base paper. When the paper receives shearing forces between the upper and lower blades of a cutter in the stage of shearing, the coating layer is cut in the form that said layer is stretched and the appearance thereof is unsightly. The stretching of the coating layer is more significant particularly on the side where no emulsions are coated, but such can be prevented by the high density PE. If the intrinsic viscosity is smaller than said range, the paper is vulnerable to scratching and if the viscosity is larger than said range, cutting quality is poor.

Title: Method for identifying input signal to optical receiver
Inventor: KITANO KOICHI
IPC: H04B10/50
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To recognize a fault or the like on an optical transmission line by discriminating whether control voltage inputted to a voltage controlled oscillator(VCO) indicates a fixed value or an irregular value. SOLUTION: A flip flop(FF) 6 compares the phase of an input signal from a photodiode(PD) 5 with that of an output signal from a VCO 8 and outputs an error signal. The error signal is inputted to a phase control circuit 7, a variation part is removed and control voltage is outputted. The VCO 8 outputs a timing signal (CLK) with frequency corresponding to the control voltage value inputted from the circuit 7. A discrimination circuit 9 discriminates whether the input waveform from the PD 5 is '0' or '1' based upon the CLK and outputs a pulse waveform. Since the method for discriminating whether an input signal is a normal optical signal including a main signal component or a signal including only a naturally radiated optical component, or the OFF of light input is provided, the reliability of an optical transmission system can be improved.
