Title: Temperature control device of heat accumulator
Inventor: ENDOU TAKUYA
IPC: G05D23/185
Filed: 1980-10-31
Abstract: PURPOSE: To have a highly reliable temperature control which does not require much  cost, by inserting an encapsulated metallic hydrogen compound into the heat accumulating material for the heat of exhaust gas from an engine and by permitting the pressure of hydrogen gas generated at the time of the heat accumulating material being at  high temperature to actuate the bypass valve for the accumulating material.   
     CONSTITUTION: The exhaust gas 100 from an engine is led through a heat accumulator  101 to be used there for warming etc. of the car. When the accumulating material is at  high temperature a valve 105 is opened to release the exhaust gas 100 out to a bypass  pipe 102 and thereby to protect the heat accumulating material. In this heat accumulating material 101 is inserted a thermosensor 104 with encapsulated metallic hydrogen  compound 106 connected to a pipe 107 whose one end is in communication to a chamber 105a in a diaphragm for operating the valve 105. Because this metallic hydrogen  compound release hydrogen when the accumulating material is at high temperature owing to a chemical reaction, the pressure in the pipe 107 becomes high to actuate the  abovementioned diaphragm and thereby to open the valve 105, and the exhaust gas 100  is thus led toward the bypass 102. A simple protection of heat accumulating material  is thus accomplished.

The fibrous material is treated with an aqueous solution of an acid (e.g. aqueous solution of hydrochloric acid) to extract the K component completely, and the resultant crystalline titanate fiber is heat-treated at >=500 deg.C to obtain the objective fiber. Since a natural titanium oxide is used as it is, the objective fiber can be manufactured at a low cost compared with the conventional process using a high-purity TiO2.
