Abstract: A waterproof cloth is provided that solves the problem in durability of the conventional biodegradable plant-derived component resin, such as a polylactic acid resin, and exhibits excellent comfort. The waterproof cloth contains a cloth having formed on one surface thereof by a coating method or a joining method a waterproof layer containing a polyurethane resin film containing from 10 to 65% by weight of a plant-derived component.

Abstract: An electromagnetic proportional flow control valve includes an electromagnetic solenoid having a bobbin with an axial bore and a fixed core in the axial bore. A valve housing defines a first port, a second port and a valve seat fludically positioned between the first and second ports, while a valve is normally in a closing position for closing the valve seat and interrupting fluid communication between the first and second ports. A movable core is fixed to the valve and positioned relative to the electromagnetic solenoid such that the movable core is attracted to the fixed core upon excitation of the electromagnetic solenoid. As a result, the valve may move from the closing position upon excitation of the electromagnetic solenoid to fluidically communicate the first and second ports. An annular diaphragm is positioned between the valve and the electromagnetic solenoid and is sealingly mounted to the movable core so as to form a fluid tight pressure chamber on a side of the diaphragm opposite the valve.
