Abstract: PURPOSE:To form a phase modulation circuit with a wide band whose modulation frequency ranges to 0 - several MHz by providing the 1st monostable multivibrator obtaining a phase difference and the 2nd monostable multivibrator deciding the duty ratio so as to provide the phase modulation with a wide range over 360 deg.. CONSTITUTION:A PLL10 generates an output signal Nf0 having a frequency being an integral number of multiple of a frequency of a reference input f0 and phase-locked and the output signal is used as a trigger to change the output pulse width of a monostable multivibrator (MM1)6 by using a modulation input. Then the trailing of the pulse triggers a monostable multivibrator (MM2)7 to make the output duty ratio constant. Thus, the output phase of the monostable multivibrator (MM2)6 being the final output is changed against the output phase of a VCO4 or the phase of the reference frequency input f0. The modulation is improved because of excellent frequency stability as well as wide variable range of pulse width of the monostable multivibrator through the adoption of the PLL.

Abstract: PURPOSE:To improve the bond strength at the pinch-off part of the container concerned and obtain tire blown container, on which no restrictions on color tone and on the design of the container and which has favorable resistance to organic solvent by a method wherein inner layer is made of manganese compound-containing polyamide layer. CONSTITUTION:The blown container concerned is molded by a publicly known blow molding method. For example, a three-layered oil tank consisting of polyamide, bonding layer and polyethylene can be molded with an accumulator type blow molding machine. At blow molding, when the inner layer of the container is made of polyamide, generally the poor bonding of pinch-off part results. In the container concerned, as its inner layer, manganese compound- containing polyamide is employed. Thus, the pinch-off part having enough bond strength can be formed and a blown container excellent in impact strength and barrier properties can be obtained.
