Title: Acceleration sensor
Inventor: MURATA RIYOUJI
IPC: G01P15/135
Filed: 1983-08-03
Abstract: PURPOSE:To prevent effectively damage such as a breakage due to impulsive force by providing an amplitude limiting mechanism to prevent an SAW element from deforming beyond a range required to measure acceleration. CONSTITUTION:A couple of amplitude limiters 17 and 17 for preventing the SAW element 10 from deforming excessively beyond the amplitude range required to measure the acceleration are fitted to both upper and lower internal surfaces of a housing 13 so that the projection sides of their curved parts face each other with the SAW element 10 between, thus constituting a mechanical amplitude limiting mechanism. Consequently, if an impulsive force is applied to the acceleration sensor and the SAW element 10 is to deform beyond a gap (g), the SAW element 10 collides with the amplitude limiters 17 and 17 positioned on both upper and lower surfaces to stop the deformation, and consequently there is no damage due to the impulsive force even when the sensitivity of the SAW element 10 is increased. Therefore, damage such as a breakage due to the impulsive force is prevented effectively.

Abstract: PURPOSE:To eliminate a pump for heating hot water by disposing a condenser having a double-pipe heat exchanger in a hot water tank to heat water as it is being supplied, and also heating hot water with fins attached to the condenser by way of natural convection. CONSTITUTION:High-temperature, high-pressure refrigerant from a compressor 25 passes through the inner pipe 30 of a condenser 27 and is circulated through expansion valve 32 and evaporator 33. When a feed water valve 26 is opened by the signal from a water level sensor 23 to admit feed water to the outer pipe 28 of the condenser 27, the feed water is directly heated by the high- temperature, high-pressure refrigerant flowing through the inner pipe 30, and enters a hot water tank 22 via a temperature regulating valve 35. The water in the hot water tank 22 is heated with fins 37 attached to the condenser 27 by way of natural convection, and when it is detected that the water is heated to a desired temperature by a temperature sensor 36, the operation of the compressor 25 is shut down. This way, a pump for heating hot water can be eliminated, and the heat loss from the condenser can be eliminated in principle.
