  • Patent number: 11768169
    Abstract: A heater section includes a plate-like ceramic body (a first substrate layer 1, a second substrate layer 2, and a third substrate layer 3) having a longitudinal direction (front-rear direction) and a short-length direction (left-right direction), and a heater 72 disposed within the plate-like ceramic body and including a lead section 79 and a heating section 76 connected to the lead section 79. The heating section 76 includes a straight portion 78 extending along the longitudinal direction, and a lead side curved portion 77b connected to one of the ends of the straight portion 78 closer to the lead section 79. The lead side curved portion 77b has a lower resistance per unit length than the straight portion 78 at one or more temperatures in the range of 700° C. to 900° C.

  • Patent number: 9989506
    Abstract: Provided is a gas sensor in which a protective cover has no looseness even by repetitive use. The gas sensor includes a sensor element for detecting a predetermined measurement target gas component in a measurement gas; a protective cover which protects a side of one end portion of the sensor element; and a housing which houses the sensor element. The protective cover includes a brim portion at one end portion of an outer surface of the protective cover. The brim portion is brought into contact with a contact surface provided in said housing, and is held between a swaging portion and the contact surface, the swaging portion extending from the contact surface while bending, so that the protective cover is fixed to the housing. The brim portion is tilted at a tilt angle of 5° or more and 15° or less relative to a plane vertical to a central axis of the gas sensor.
