| titleOfInvention | Hot-wire type air flow rate sensor and its manufacture |
| abstract | PURPOSE: To easily manufacture a hot-wire type air flow rate sensor having a cavity in the inside with a high automation rate by winding a metallic wire to a metallic core whose cross section is elliptical, and welding a lead wire to its tip part, and thereafter, covering it with a glass member and burning it. n CONSTITUTION: A platinum wire 2 being a heating resistor is wound continuously to a molybdenum core 5 whose cross section is elliptical by an automatic winding machine, it is cut to length of a one-piece portion of an element, and on both ends, a lead wire 3 is welded in a connecting pat 21. In such a state, the periphery is covered with a glass member 41 by an electrophoresis method, and thereafter, the glass member 41 is burned. At the time of burning, as a temperature rises, the molybdenum core 5 is sublimated and eliminated, and thereafter, a glass member 42 of the second layer is covered by an immersing method and burned, by which a heating resistor 2 having a cavity whose cross section is elliptical in the inside is obtained. In such a way, the automation rate of manufacture is raised, and the workability can be improved. n COPYRIGHT: (C)1989,JPO&Japio |
