    摘要: There is provided a multilayer bottle including outermost and innermost layers each made mainly of a polyester (A) and at least one barrier layer interposed between the outermost and innermost layers. The polyester (A) is a thermoplastic resin obtained by polymerizing a dicarboxylic acid component containing 80 mol % or more of terephthalic acid with a diol component containing 80 mol % or more of ethylene glycol. The barrier layer is composed of a polyamide (B) and a polyamide (C). The polyamide (B) is obtained by polycondensing a diamine component containing 70 mol % or more of m-xylylenediamine with a dicarboxylic acid component containing 70 mol % or more of an α,ω-linear aliphatic dicarboxylic acid having 4 to 20 carbon atoms. The polyamide (C) has a higher saturation water content than that of the polyamide (B) as measured at 23° C. and 50% RH under 1 atm, and a content of the polyamide (C) in the barrier layer is 20% by weight or less on the basis of a weight of the barrier layer. The multilayer bottle hardly suffers from delamination upon dropping or upon exposure to impact and, therefore, is not required to have a shape with less irregularities or less bends for preventing the delamination, and further has a large freedom of design choice.

    摘要: A pressure regulator for controlling pressure with high response and high accuracy even a flow change occurs on the downstream side. The pressure regulator (1) regulates the rate of inflow into an isothermal pressure vessel (13) for the gas supplied from a gas supply source (10) by means of a servo valve (11) to maintain the constant pressure in the isothermal pressure vessel (13). Pressure control means (a computer (16)) operating the servo valve (11) has as a main loop a pressure control system for feedback-controlling the pressure in the isothermal pressure vessel (13) measured by a pressure gauge (14) and has therein a rate-of-inflow-control system for feedback-controlling the rate of flow measured by a flow meter (12), an observer for estimating the rate of outflow from the isothermal pressure vessel (13) according to the rate of inflow and the derivative of the pressure in the isothermal pressure vessel (13) measured by a pressure differentiator (15), and a model follow-up control system for feed-backing the estimated rate of outflow to the rate-of-inflow control system.
