Filed: 1993-07-20
Abstract: PURPOSE:To hold a voltage of an output terminal constant by so disposing conductive type transistors of a power source side and a ground side that threshold value changes of the transistors are symmetrical to an output terminal as the center. CONSTITUTION:An absolute value of a threshold value of an NMOS transistor is assigned to be Vth, and an absolute value of a threshold value of a PMOS transistor is assigned to be Vtp. Resistors 31, 32 are so designed that a voltage of a between a NMOS 24 and a PMOS 18 becomes voltage Vdd/2 of a half of a power source voltage Vdd. In this case, a drain voltage of the NMOS 24 becomes (Vdd/2+Vtn), and a drain voltage of the PMOS 18 becomes (Vdd/2-Vtp). Since a gate voltage of an NMOS 25 becomes (Vdd/2+Vtn) and a gate voltage of a PMOS 19 becomes (Vdd/2-Vtp), a voltage of an output terminal 1 becomes Vdd/2. When a load is connected to the terminal 1 and hence the voltage of the terminal 1 is raised beyond Vdd/2, the NMOS 25 is turned off, and when it is lowered beyond the Vdd/2, the PMOS 19 is turned off, and the terminal 1 is held at the Vdd/2.

Title: Thermally-actuated steam trap
Inventor: KOIKE TADASHI
IPC: F16T1/10
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To prevent water hammering from occurring by packing expanding media of which expansion and contraction temperatures are different from each other in right and left of two internal spaces, and forming a seal surface to close a lead path of a valve seat member at a valve member and a seal surface to close through holes of the valve member on the valve seat member. SOLUTION: An expanding medium 23 is filled into an internal space formed with a wall member 13 and a right-side diaphragm 14, and an expanding medium 25 is filled and sealed into an internal space formed with the wall member 13 and a left-side diaphragm 15. Also the expanding medium 25 is a liquid lower by several degrees in boiling point than the expanding medium 23. When the temperature inside a valve chamber 3 is lowered, the expanding medium 23 is contracted to move the diaphragm 14 upward, and then the expanding medium 25 is contracted to move the diaphragm 15 upward. By this, the seal surface 26 of a valve member 17 opens the lead path 8 of a valve seat member 7, and the seal surface 37 of the valve seat member 7 opens a through hole 16 of the valve member 17 so as to drain condensate from an outlet 5.  Thus water hammering can be prevented because abrupt opening and closing operations are not performed.
