9. The apparatus as recited in claim 1 wherein said laminated together interleaved portions are drilled and plated using a plated through hole (PTH) process, creating a PTH connection between the conductors carried by adjacent dielectric layers.
10-18. (canceled)
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A flow amount control apparatus comprising:
a supply tank for storing a liquid;
a main pipe having a first open end connected to the supply tank in a water tight manner and a second open end disposed at a position lower than the first open end with respect to the gravity for transferring the liquid from the supply tank to the second open end;
a supply valve capable of preventing the liquid from flowing into the main pipe, the supply valve being placed at a position between the supply tank and the second open end;
a branch pipe having
a third open end connected to the main pipe in a water tight manner at a position between the supply valve and the second open end and
a fourth open end disposed at a position above the third open end with respect to the gravity;
a flow amount adjustment means for controlling an amount of the liquid flowing between the third open end and the second open end in response to a control signal, the means being connected to at least one of the second open end and the fourth open end;
a liquid level detection unit for detecting a liquid level in the branch pipe at two positions;
a timer; and
a controller for controlling the flow amount adjustment means in response to a first signal sent from the timer and a second and third signals sent from the liquid level detection unit.
2. The flow amount control apparatus according to claim 1, wherein the flow amount adjustment means includes:
a pressure nozzle having a barrel, a chamber, and an outlet, the barrel and chamber being provided in a through hole formed therein;
a needle arranged in the chamber and movable forward and backward with respect to the outlet, the needle having a root fixed to a micrometer having a thimble;
an air path for blowing an air into the barrel;
a liquid path communicating with the chamber and the second open end; and
a stepper motor for holding the thimble of the micrometer.
3. The flow amount control apparatus according to claim 1, wherein the flow amount adjustment means includes:
a gas source capable of supplying a gas having a first predetermined pressure higher than an atmospheric pressure;
a gas pipe connecting the gas source to the fourth open end in an air tight manner; and
an electro pneumatic transducer provided between the gas source and the gas pipe for adjusting the pressure of the supplied gas to a second predetermined pressure lower than the first predetermined pressure and higher than the atmospheric pressure to supply the pressure adjusted gas to the gas pipe.
4. The flow amount control apparatus according to claim 3, wherein the gas is an inert gas.
5. The flow amount control apparatus according to claim 1, wherein the liquid level detection unit includes an optical sensor for detecting the liquid level in the branch pipe by emitting light on the branch pipe from outside thereof.
6. The flow amount control apparatus according to claim 1, further comprising an inert gas purge means for purging the supply tank and the fourth open end with an inert gas.
