  • Publication number: 20240079492
    Abstract: A semiconductor device includes a second deep layer between a first deep layer and first current distribution layer and a base region in an active region and in a part of an inactive region adjacent to the active region. The second deep layer has a second stripe portion including lines connecting to the base region and the first deep layer. The semiconductor device further includes a second current distribution layer between the first current distribution layer and the base region and arranged between the lines of the second stripe portion. The first deep layer has a first stripe portion including a plurality of lines, and each line has an end portion connecting to a frame-shaped portion and an inner portion on an inner side of the end portion. The width of the end portion is equal to or greater than the inner portion.

  • Patent number: 10690549
    Abstract: A mounting structure of a temperature sensor is adapted to mount a temperature sensor adapted to measure a temperature of a coil to a stator constituted by arranging a plurality of sets of a stator core, the coil wound around the stator core, and an insulator ensuring insulation between the stator core and the coil. The mounting structure of a temperature sensor comprises a holder fixing portion fixed to the insulator, and a sensor holding portion formed integrally with the holder fixing portion and holding the temperature sensor on a coil end portion of the coil. In the sensor holding portion, a storage groove adapted to store the temperature sensor is formed, and at a groove bottom of the storage groove, a sensor pressing portion adapted to press the temperature sensor to the coil end portion is formed.

  • Patent number: 9347949
    Abstract: The present invention provides a compound represented by the formula (I): or a salt thereof; and a method of quantitatively analyzing an amino group-containing target substance, including labeling a target substance in samples by using, as a labeling compound, two or more of such compounds having a mutually different mass due to isotope labeling, to confer a mass difference to the target substance between two or more samples, and the like.
