  • Patent number: 11979017
    Abstract: Provided is a novel power conversion device that enables estimation of a temperature of a power device without using a temperature sensing diode and can accurately estimate a temperature and a current of a current sensing element that observes a main current. A measurement voltage (Vref) is applied between source terminals (31s and 49s) of a main control element 31 and a current sensing element 49 in a state in which the main control element 31 and the current sensing element 49 are turned off, and a temperature of a power device 30 is estimated from a current (Ib) flowing between the source terminals (31s and 49s) of the main control element 31 and the current sensing element 49 at the time of the application by using the fact that a resistance value of a semiconductor substrate between the source terminals of the main control element 31 and the current sensing element 49 has temperature dependency.

  • Patent number: 7176014
    Abstract: A solid medium having a 10 minute-average water absorption rate of at least 0.05 ml/minute, which is obtainable by a method for producing a solid medium comprising the steps of dissolving components of the solid medium other than solvent water into the solvent water, solidifying the obtained solution, and drying the solidified medium to remove water, wherein water is removed in such an amount that the solid medium after the removal of water should have the 10 minute-average water absorption rate of at least 0.05 ml/minute, and the amount of the solvent water is larger than a prescribed amount by an amount almost equal to the amount of the water to be removed. The solid medium does not cause growth inhibition of microorganisms due to drying, shows a superior water absorption rate to enable application of a larger amount of a sample in a short period of time, and is suitable for quick and accurate measurement tests of microbial numbers.
