  • Publication number: 20240099021
    Abstract: According to one embodiment, a magnetic memory device includes a lower insulating layer, first and second conductive portions provided in the lower insulating layer, first and second memory cells provided on the lower insulating layer and on the respective first and second conductive portions, and each including a magnetoresistance effect element, a switching element and a bottom electrode connected to corresponding one of the first and second conductive portions. As viewed from a third direction, a width of each of the first and second conductive portions is less than a width of a corresponding bottom electrode. The lower insulating layer has a void under a region between the first and second memory cells.

  • Patent number: 11018289
    Abstract: Disclosed is a thermoelectric generation system that generates electricity using waste heat from a steam condenser that exchanges heat with steam as cyclic water flows through a high temperature portion and a low temperature portion, the thermoelectric generation system including: a first hot-water discharge line used to discharge the cyclic water passing through the high temperature portion; a cyclic water circulation line through which the cyclic water from under water circulates; and a thermoelectric generation unit that generates electricity on the basis of a temperature difference between a temperature of the cyclic water flowing through the first hot-water discharge line and a temperature of the cyclic water flowing through the cyclic water circulation line.

  • Patent number: 9121449
    Abstract: A slide bearing has an oil supply passage formed in a lower bearing portion, that supplies lubricating oil into clearance between an outer peripheral surface of a rotating shaft and lower and upper slide surfaces, and an oil discharge passage formed in the lower half bearing portion and discharges the lubricating oil from the clearance. The oil supply passage has a downstream portion and the oil discharge passage has an upstream portion which is provided at positions on opposite sides of the rotating shaft. The oil supply passage has an upstream portion extending toward the upstream portion of the oil discharge passage, and the oil discharge passage has a downstream portion extending toward the downstream portion of the oil supply passage.
