Title: Forced circulation type bath apparatus
Inventor: KONDO FUMIO
IPC: F24H1/00
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent a microcomputer meter from an error in action and make it less in the number of times for the combustion of gas, to the bather's unpleasantness, to be forcedly forbidden. SOLUTION: A suspension time-measuring timer at all times measures an unbroken time of the suspension of combustion (S19) and does the count (S26) so as to make it as least as possible in number of times for the combustion to be forcedly forbidden. This forced forbiddance of combustion is effected only in a certain time zone (S17) specified as a time period in which the use of the hot-water supply part is not frequent (S30) and, therefore, the probability is low that other gas appliances are used during the forced forbiddance. Moreover, the time before the start of the forced forbiddance is made variable (S28) so that it does not occur for there to be wasteful application of forced forbiddance in regard of, for example, changes of seasons.

Filed: 1989-12-22
Abstract: PURPOSE: To detect the sudden change of pressure by forming the walls of two pressure chambers out of a gas permeable wall for changing the pressure of the pressure chambers at the prescribed rate and a diaphragm moving to the prescribed position in response to the danger change rate of pressure. CONSTITUTION: The first and the second pressure chambers 38 and 40 are formed out of parts 16 and 15 in a cylindrical housing 12. In addition, one of the walls of the pressure chambers 38 and 40 is formed out of a flexible diaphragm 32, and independently movable between the first position and the second position in response to the danger change rate of pressure in the chamber 38. Also, one of the walls of the pressure chambers 38 and 40 is made of a gas permeable wall. In this case, the gas permeable wall is formed to have permeability so that the pressure of the pressure chambers 38 and 40 becomes uniform for preventing the diaphragm from detecting a pressure change when a pressure change rate in the chamber 38 is low, as well as to have permeability of such an extent as not preventing the travel of the diaphragm 32, upon the change of the pressure at the danger change rate.  As a result, a sudden change in the pressure of the pressure chambers 38 and 40 is detected and the safety of a tire is improved.
