  • Patent number: 11977042
    Abstract: An oxygen sensor for detecting gas concentration based on either an electric current value or a resistance value measured when a voltage is applied to a sensor element includes gaps formed between electrodes arranged in an element main body and ridges where surfaces of an element touch each other. These gaps will be escaping parts for expansion and contraction of electrode material that accompany thermal expansion and contraction of a sensor main body, and concentration of thermal stress at edge parts of the element main body may thus be eliminated, thereby alleviating thermal stress on the oxygen sensor. This allows provision of a gas sensor that controls generation of cracks in the element and that is stably usable over a long period of time.

  • Patent number: 11757546
    Abstract: A method with which the reception sensitivity of a communication device can be measured accurately and with satisfactory reproducibility and a method with which the effect of noise control performed upon a communication device can be accurately evaluated. A first communication device in a nonreflective environment in an anechoic chamber wirelessly receives a test signal transmitted from a pseudo base station through an attached antenna thereof at the same time when a second communication device near the first communication device receives the test signal through a signal line. The first communication device is simultaneously subjected to the interference of noise generated by the second communication device at the attached antenna. Thus, the noise is made to interfere with the attached antenna of the first communication device without disassembling the first communication device and moving the first communication device in the nonreflective environment.
