  • Patent number: 8632245
    Abstract: A temperature sensor is provided that can easily make possible stuffing with the filler or burying of the temperature detector element so that faster temperature response can be achieved. A temperature sensor has a closed-bottom tubular shaped case, a temperature detector element inserted and accommodated in the case, and a filler filled in the case and sealing the temperature detector element. The temperature sensor is provided with a filler flowing portion formed in a relative gap between the case and the temperature detector element along an insertion direction of the temperature detector element and having a gap relative to the temperature detector element larger than that relative to the remainder portion of the gap.

  • Patent number: 4907896
    Abstract: There is disclosed a maximum reading, temperature measuring device, such as a clinical thermometer, composed of a bulb containing an expandable liquid, such as mercury, an elongated tube with a central bore into which the liquid expands when heated, and a flow control member positioned intermediate the tube and bulb and sealed to each. The flow control member is a short length of tubing having a central bore that is sufficiently small in diameter to form a constriction that inhibits reverse flow of the liquid.
