  • Patent number: 11948823
    Abstract: A substrate treating apparatus includes a carrier platform, a transport mechanism, and a controller. The carrier platform places a carrier thereon. The carrier includes a plurality of shelves arranged in an up-down direction. The shelves are each configured to place one substrate thereon in a horizontal posture. The transport mechanism is configured to transport a substrate to a carrier placed on the carrier platform. The controller controls the transport mechanism. The transport mechanism includes a hand and a hand driving unit. The hand supports a substrate. The hand driving unit moves the hand. The controller changes a height position of the hand when the hand is inserted between two of the shelves adjacent to each other in the up-down direction, depending on a shape of a substrate taken from or placed on one of the shelves by the transport mechanism.

  • Patent number: 11850623
    Abstract: Disclosed are a substrate treating apparatus and a substrate transporting method. The substrate treating apparatus includes a first transport mechanism. The first transport mechanism includes a hand. A hand includes a base, a suction portion, a first receiver, a second receiver, and a receiver driving unit. The suction portion is attached to the base. The suction portion flows gas along a top face of a substrate, and sucks the substrate upward without contacting the substrate. The first receiver and the second receiver are supported on the base. The first receiver and the second receiver are disposed below the substrate sucked by the suction portion. The first receiver and the second receiver can receive a back face of the substrate. The receiver driving unit moves the second receiver with respect to the base. The receiver driving unit causes the second receiver to access the first receiver and to move away from the first receiver.

  • Publication number: 20230302501
    Abstract: A substrate processing apparatus delivers a gas between a lower surface of a substrate and a base surface of a base part to form an airflow flowing radially outward and to cause a pressure drop in a space between the substrate and the base part by the Bernoulli effect. The base surface includes a second surface sloping upward in a radially outward direction. A third surface slopes downward in a radially outward direction from the outer peripheral edge of the second surface. A fourth surface is an annular surface contiguous to the lower edge of the third surface. The fourth surface expands radially outward outside the outer peripheral edge of the substrate in the radial direction. Accordingly, it is possible to suppress adhesion of a processing liquid to the lower surface of the substrate and to improve the stability of holding the substrate.

  • Publication number: 20230290670
    Abstract: In a substrate holder, a gas supply part sends out a gas to the space between the lower surface of a substrate and a base surface of a base part to form a radially outward airflow. A division plate is arranged radially outward of the outer peripheral edge of the substrate on the base surface of the base part to surround the substrate. The inner peripheral edge of the division plate and the outer peripheral edge of the substrate face each other in the radial direction with a space in between. The upper surface of the division plate is located below or at the same position in the up-down direction as the upper surface of the substrate. An annular passage is provided between the lower surface of the division plate and the base surface of the base part.

  • Patent number: 8547479
    Abstract: A display apparatus includes a conversion unit for converting first video data having a first frame rate to second video data having a second frame rate which is “n” times as high as the first frame rate (“n” being an integer of two or larger), and a display unit for displaying the second video data. When the first video data is video data of two successive frame images having different brightnesses, the conversion unit performs a first frame rate converting process for converting the first video data to the second video data by outputting a frame image group made of two successive frame images in the first video data “n” times in a row at the second frame rate. Consequently, the frame rate converting process can be performed without causing a deterioration of a visual effect such as an HDR effect, and a viewing environment comfortable for the user can be realized.

  • Patent number: 8027559
    Abstract: An image reproducing apparatus is connected to a display device via a video data transmitting unit and a file data transmitting unit and is driven by a battery. The image reproducing apparatus calculates a first electric power required to transmit video data to the display device and a second electric power required to transmit file data to the display device, and acquires a remaining amount of electric power in the battery. Then, the image reproducing apparatus judges whether the acquired remaining amount of electric power in the battery is equal to or larger than the first electric power, is equal to or larger than the second electric power but smaller than the first electric power, or is smaller than the second electric power, and determines whether the image data is to be transmitted as the video data or the file data.
