Title: Apparatus and method for controlling water heater
Inventor: TSUGAI YASUO
IPC: F23N3/08
Filed: 1995-02-02
Abstract: PURPOSE: To provide an apparatus and a method for controlling a water heater in which a desired voltage can be applied to a load. CONSTITUTION: Before a water heater in which a voltage is applied to a load 14 in response to the amplitude of a control signal voltage divided from the output voltage of a power source 2 is delivered, when a standard voltage to be output from the power source 2 is voltage-divided as the control signal, the divided value to be applied with the standard voltage to the load 14 is stored in a read only memory 11 as an initial divided value, and the ratio of the standard voltage to the real output voltage of the power source 2 is stored as a correction coefficient in a nonvolatile memory 12. In the case of a real operation, when the real output voltage is divided from the initial divided value and the coefficient as a control signal, the correction divided value to be applied by the standard voltage to the load 14 is calculated to form a control signal.  Thus, even if the power source outputs the voltage different from the standard, a desired voltage can be applied to the load.

IPC: F16K31/122
Filed: 1981-02-05
Abstract: PURPOSE:To control securely lift of the poppet from outside by controlling the position of poppet, which is always maintained open due to the fluid pressure at the pump side, by means of the pilot pressure only; a command pressure from outside; independently of the pump side pressure. CONSTITUTION:When both the pilot pressure Pi and the liquid pressure of pump are zero, a stepped piston 7 is positioned uppermost due to a spring 17, and a poppet 3 is touched to a valve seat 4 by its dead weight, desconnecting a primary side path 13 from a secondary side path 18.
