  • Patent number: 11515227
    Abstract: Semiconductor devices laterally surrounded by at least one dielectric material portion are formed over a substrate. At least one edge seal ring structure is formed around the semiconductor devices and the at least one dielectric material portion. One or more of the at least one edge seal ring structure has a horizontal cross-sectional profile that includes laterally-extending regions that extend laterally with a uniform width between an inner sidewall and an outer sidewall, and notch regions connecting neighboring pairs of the laterally-extending regions and having a greater width than the uniform width. Cavities in the laterally-extending regions are connected to cavities in the notch regions to allow outgassing from the material of the at least one edge seal ring structure.

  • Publication number: 20220106653
    Abstract: Provided is a method for executing a quenching method in which an object to be treated that is a quenching target is cooled with a quenching coolant that is a coolant for quenching, in which the object to be treated is moved inside the quenching coolant accumulated in a cooling tank, by a moving device for moving the object to be treated, and at least from when the object to be treated comes into contact with the quenching coolant until a surface of the object to be treated undergoes martensitic transformation, a state in which a relative speed of the object to be treated and the quenching coolant is slower than a moving speed of the object to be treated is maintained.

  • Patent number: 9589683
    Abstract: A reactor shutdown system includes a reactor, a control-rod drive unit that can drive a control rod in pulling and inserting directions with respect to a fuel assembly, a power source that can supply power to the control-rod drive unit, and a power converter that is provided between the control-rod drive unit and the power source, in which when power supply is cut off, the control-rod drive unit inserts the control rod into the fuel assembly to stop nuclear reaction in the reactor, and the reactor shutdown system includes a reactor trip breaker provided between the power converter and the control-rod drive unit, a safety protection-system device that controls the reactor trip breaker to cut off power supply to the control-rod drive unit, and a CCF device that controls the power converter to cut off power supply to the control-rod drive unit.

  • Publication number: 20070019116
    Abstract: A broadcasting timetable is newly created at one step. If a broadcasting state of a channel is changed at certain times' intervals in this broadcasting timetable, a processing goes to a next step. At the next step, the broadcasting state of each channel is judged at a time at which the broadcasting state is changed, and a judgment result is temporarily stored. At a next step, a content stored in the broadcasting timetable is compared with the judged broadcasting state to determine whether they are coincident. If they are coincident, a processing goes to a next step; otherwise, the broadcasting timetable is updated.

  • Patent number: 5184224
    Abstract: A transmission-type video projection television system employs a transmission-type screen for displaying an image projected from a rear projector for visual observation by an observer in front of the screen. The transmission-type screen has Fresnel and lenticular lenses, one of which has an electrically conductive layer or a metal member on its surface to prevent the lens from being electrostatically charged, so that dust or dirt particles will not be attracted to the screen.
