  • Patent number: 11646215
    Abstract: A load port apparatus connects a main opening of a wafer transportation container to a frame opening. The apparatus includes an installation unit, a frame unit, a flange clamp unit, and a detection unit. The installation unit includes an installation table configured to install the container and relatively move to the frame opening. The frame unit is upright upward from the installation unit and includes the frame opening. The flange clamp unit includes an engagement section and a drive section. The engagement section is engageable with a flange surrounding an outer circumference of the main opening. The drive section drives the engagement section to carry out an engagement operation and a separation operation. The detection unit detects the engagement operation by the flange clamp unit with classification into a normal engagement operation and an abnormal engagement operation.

    Abstract: After low-temperature finish rolling has been performed on a steel material having a certain chemical composition, cooling is performed at an average cooling rate of 10° C./s or higher to a temperature of 500° C., rapid cooling is further performed in a temperature range from a Ms temperature to a temperature of (Ms temperature - 200° C.), coiling is thereafter performed in a low temperature range of 250° C. or lower, and the coiled steel sheet is uncoiled and further subjected to rolling with a certain amount or more of rolling load per unit width and the like. Consequently, it is possible to obtain a high-strength hot-rolled steel sheet having a microstructure including, in terms of area fraction, 95% or more of a martensite phase at a position located at ¼ of the thickness of the steel sheet, in which an average aspect ratio of prior austenite grains is 3.0 or more.
