IPC: H03H9/10
Filed: 1986-04-15
Abstract: PURPOSE:To prevent the superposed part of an electrode and a case from being damaged even if high temperature is applied to these parts by forming the electrode by a material having the coefficient of thermal expansion approximate to that of the case. CONSTITUTION:The case 10 is formed by alumina ceramic material and the electrode 30 is formed by a material having the coefficient of thermal expansion approximate to that of the ceramic material. For instance, the alloy of 58% Fe and 42% Ni or the alloy of Fe-Ni-Co is recommended as the material. In addition, a material obtained by coating the whole surface of an alumina ceramic material 31 having a cap with a conductive film 32 based on electroless plating is also considered. When the oscillator is fixed by soldering, the electrode 30 and the case 10 are highly heated, but since the electrode 30 is formed by the material having the coefficient of thermal expansion approximate to that of the case 10, thermal expansion is approximately equivalently generated and the superposed part of both the parts is prevented from the generation of large stress.

Abstract: PURPOSE: To accelerate the rising time of the heating operation and to improve the heating effect of the captioned apparatus by a method wherein a liquid heat medium section, a steam heat medium section and a plurality of lines of heat transfer passages are provided in the heat exchanging apparatus which is used for a central  heating system utilizing a hot water boiler.  
     CONSTITUTION: In case a floor heating operation is performed, primary side hot water is introduced into an  intermediate heat exchanger 151 from the liquid heat medium section 151 to thereby heat a heat medium 156.  The heat medium 156 heated to a high temperature heats a secondary circulating water heat pipe 155 and the  secondary circulating water heated by the heat pipe 155 circulates through a floor heating panel to thereby perform the floor heating operation. Further, when a heat medium 157 which is evaporated and heated by the  liquid heat medium section 151 fills an evaporation section 152, the level of the heat medium 156 at the liquid  heat medium section 151 lowers and the amount of heat exchange between a primary side heat transfer pipe  154 and the secondary heat transfer pipe 155 decreases so that the floor panel heating capacity decreases. On  the other hand, as a room heating operation is in progress and the heating load is in a reduced condition, the  primary side heat transfer pipe 154 and the secondary transfer pipe 155 are brought under a balanced condition  and the level of the heat medium 156 is also brought into equilibrium with the heating load. Thus, the heating  operation is started earlier and the heating effect of the heat exchanging apparatus can be improved.
