IPC: G05D23/13
Filed: 1993-12-27
Abstract: PURPOSE:To prevent the rise of the internal pressure or a mixing valve due to the afterheating of a hot water supplier after the stoppage of the supply of hot water by starting a timer part at the time of the stoppage of the supply of the hot water, and opening a water supply valve for a definite period of time at several times after the lapse of the prescribed time from the stoppage of the supply of the hot water. CONSTITUTION:The timer part 9 starts counting when the instruction of the stoppage of the supply of the hot water is given by an operating part 7, and after the prescribed time elapses, it outputs a signal to a water supply control valve 8 so that the water supply valve 6 is opened for the definite period of time at several times, and the water supply control valve 8 receives this signal, and opens the water supply valve 6 for the definite period of time at several times. The operating part 7 repeats the start and the stoppage of the supply of the hot water by a hot water supply switch. Thus, the rise of the internal pressure of the mixing valve 2 after the stoppage of the supply of the hot water due to the afterheating of the hot water supplier 1 can be prevented, and the discharge of the hot water at the time of depressurization is prevented that the splash of hot and cold water on a user can be prevented.

Abstract: PURPOSE:To inspect an opening angle of an opening/closing piece by providing a variable resistor whose resistance value varies with the rotation of a rotating shaft at a part of a shaft of one opening/closing piece of an opening/closing device while a rotating means is mounted on the other opening/closing piece to rotate a rotating shaft of the variable resistor. CONSTITUTION:One opening/closing piece 1 has a variable resistor 3 buried into a hinge part 1a thereof. A hinge shaft 4 inserted through a hinge part 2a of the other opening/closing piece 2 is inserted into one side of the hinge section 1a while a non- rotating shaft 5 is inserted into the other hinge part 2b in such a manner as not to rotate. The non-rotating shaft 5 is inserted into the hinge section 1a in such a manner as to rotate. The tip of the non-rotating shaft 5 is inserted into a linear groove formed on an end face of the rotating shaft 3a of the variable resistor 3 to transmit the rotation of the non-rotating shaft 5 to the rotating shaft 3a of the variable resistor 3. With the rotation of the rotating shaft 3a of the variable resistor 3, a lead 6 connected to two terminals varying in resistance value is led out from inside the opening/ closing piece 1. When the variable resistor 31 with an angle of rotation of the rotating shaft 3a proportional to the resistance value is used, the opening/closing angle between the opening/closing pieces 1 and 2 can be learned by measuring the resistance value.
