  • State sensing system for eFuse memory
    Patent number: 8780604
    Abstract: An eFuse circuit may include a wordline, a first eFuse, a first logic gate, a first blowFET, and a first bitline discharge device. The first eFuse may have a first end coupled to the wordline and a second end. The first eFuse may have a first resistance when unblown and a second resistance when blown. The first logic gate may be coupled to the first end of the first eFuse. The first logic gate may be capable of driving enough current to blow the first eFuse. The first blowFET may have a source coupled to a first supply voltage, a gate coupled to a program signal, and a drain coupled to the second end of the first eFuse. The first bitline discharge device may have a gate coupled to the second end of the first eFuse, a source coupled to the first supply voltage, and a drain coupled to a first bitline.

  • Stator core cooling for dynamoelectric machines
    Patent number: 4217511
    Abstract: Improved cooling is provided for the end regions of the stator cores of large dynamoelectric machines where substantial losses result from the presence of axial magnetic flux. Additional cooling is provided in the tooth portion of the end regions of the core by means of axial vents in the slots for flow of coolant gas between the winding conductors and the slot walls, thus cooling the teeth and reducing excessive heating, while the heated slot wall is spaced from the winding insulation and direct contact is prevented.
