20140290039 | METHOD FOR MANUFACTURING GAS SENSOR - Among first and second swaged sections, the second swaged section begins to be swaged prior to the first swaged section. Hence, a strong force can be prevented from acting on a rubber plug in a free state at a time and the first swaged section can begin to be swaged in such a state that a portion of the rubber plug that corresponds to the second swaged section is aligned as compared to the case where the first and second swaged sections begin to be simultaneously swaged. This prevents the position of the rubber plug from being significantly varied during swaging and also prevents the rubber plug from protruding from an outer tube. | 10-02-2014 |
20140290333 | GAS SENSOR - An outer tube and a rubber plug are swaged at two sites, a first swaged section located on the side of connections between contact fittings of a connector and leads and a swaged section located closer to an open end of the outer tube than the first swaged section, such that the inside diameter of a portion of the outer tube is greater than the inside diameter. This prevents reduction of the detection accuracy of a gas sensor because sealing properties can be enhanced by heavily swaging at the second swaged section than the first swaged section. Additionally, excessive force can be prevented on the connections and the leads by lightly swaging the first swaged section rather than the second swaged section. Thus, the disconnection between the connector and the leads can be prevented. | 10-02-2014 |

20120248071 | RESISTANCE WELDING METHOD AND RESISTANCE WELDING JIG - In resistance welding, an end portion and a flange portion are welded together at contact surfaces thereof by applying a voltage between two electrodes a while an inner casing and a main metal piece are pressed in directions toward each other. When a shearing stress due to the pressure is applied to a ceramic guide pin, the guide pin is more resistant to wear as compared to a phenolic resin guide pin, for example. In addition, a clearance is provided between a large-diameter portion of the guide pin and an inner surface of a guide-pin insertion hole. Accordingly, the guide pin is capable of tilting in the radial direction, to partially absorb the shearing stress. Therefore, the guide pin is more resistant to breakage compared to a non-tilting ceramic guide pin. Thus, the life of the guide pin used in the resistance welding process can be prolonged. | 10-04-2012 |

20110281472 | CONNECTOR - Each of contact fittings is obtained by bending a die-cut member having a metal plate portion of substantially rectangular shape and a metal piece connecting to a long side of the metal plate portion.

Then, the metal piece is bent along the length of the metal plate portion to form a hook to be retained by a first housing or a second housing. Therefore, as compared to a structure in which hooks are orthogonal to the length of metal plate portions and bend outward from contact fittings, the arrangement width of the contact fittings arranged in a direction substantially orthogonal to the length of the contact fittings can be reduced. | 11-17-2011 |
