IPC: B63B22/00
Filed: 2007-02-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a buoy used for mooring a vessel in fishery harbors, harbors, and other facilities that emits light even without using a power source or a mechanical device.  <P>SOLUTION: A light storage material is mixed in a skin material or a skin coating material of the mooring buoy 1 to make the mooring buoy 1 luminous.

Title: Fluid control valve
Inventor: NABEI TATSUMI
IPC: F16K31/365
Filed: 2007-02-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a fluid control valve in which repulsive force against pressing force from a pressure operating chamber is obtained by a compression coil spring and the compression coil spring and a primary-side fluid chamber are separated from each other by a diaphragm, capable of preventing secondary pressure from fluctuating even when primary pressure fluctuates.  <P>SOLUTION: The compression coil spring 36 for generating the repulsive force against the pressing force from the pressure operating chamber R3 is disposed below the diaphragm 34. An effective pressure-receiving diameter of a valve seat portion 25c is set larger than that of the diaphragm 34 on the primary side. When the valve opening degree is changed due to the fluctuation of the primary pressure, the compression coil spring 36 expands or contracts so that the load thereof also fluctuates. Even when the spring load fluctuates, a change in load of the compression coil spring 36 is canceled by a change of the primary pressure due to a difference between the effective pressure-receiving diameters. Therefore, it is possible to keep the secondary pressure constant irrespective of the expansion/contraction of the compression coil spring 36.  <P>COPYRIGHT: (C)2008,JPO&INPIT
