Abstract: A mass flow controller has a sensor section that generates an electrical signal, dependent on the measured flow rate. The controller sends a control signal to a magnetic field generating unit, dependent upon the actual flow rate and the desired flow rate, which in response, generates a magnetic flux in the direction of the fluid input to the fluid output through the body of the controller. This means that the magnetic flux is concurrent with the fluid flow within the mass flow controller body. The magnetic flux alters the position of a plunger button assembly, located between the bypass chamber and the fluid output, relative to an orifice plate to control the flow rate to obtain the desired output flow. By incorporating the proportional control valve within the mass flow controller body, the need for a separate and large valve section is eliminated, reducing the size and cost of the controller.

Abstract: A safety valve has a valve body, a piston contained in the valve body, a soluble alloy filled between said piston and said valve body, and a spring inserted between the piston and the valve body. The piston includes a path connecting both ends thereof, and has a first gas pressure receiving surface and a second gas pressure receiving surface at both ends. The first and second gas pressure receiving surfaces have the same area; the piston works as a balanced piston where the gas pressure in the fuel tank functions in reverse directions. As a result, no gas pressure is applied to the soluble alloy but only the energizing force of the spring is applied. Therefore, the pressure applied to the soluble alloy can be kept constant without regard to the increase of the gas pressure.

Abstract: A molten metal pouring time determining apparatus determines a proper time for pouring molten metal into a die. A mass of metal is placed in a melting pot. The melting pot and the metal mass are radio frequency (RF) induction heated with RF signal modulated with a low frequency signal. A light receiver receives light emitted by the metal mass heated in the melting pot and develops a received-light representative signal. A high-pass filter extracts a high frequency component developed by a sudden change in the received-light representative signal caused by the melting of the metal mass. A comparator develops an output signal when the output signal of the high-pass filter exceeds a reference signal. When the comparator output signal remains above the reference signal for a predetermined time period, a timer generates a molten metal pouring command signal.
