Abstract: An apparatus and method for measuring air currents on the surface of a substrate, which can accurately measure the magnitude and direction of air currents on the surface of a wafer with wafer-type air current measurement sensors, are provided. The apparatus includes: a first air current measurement module measuring a magnitude of air currents on a surface of a first substrate, which is processed in accordance with a semiconductor manufacturing process; a second air current measurement module measuring a movement direction of the air currents; and a power module supplying power to the first and second air current measurement modules, wherein the first air current measurement module, the second air current measurement module, and the power module are mounted on a second substrate, which has the same shape as the first substrate.

Abstract: Disclosed is a transparent ice manufacturing system including a reservoir tank, in which a liquid is stored, a mold having a cavity, in which the liquid supplied from the reservoir tank is filled to form ice, a cooling part that cools one area of the mold to manufacture ice while freezing the liquid from the one area to an opposite area of the mold, and a fluid circulation part provided between the reservoir tank and the mold, and that circulates the liquid between the reservoir tank and the cavity while the liquid is frozen in the cavity.

Abstract: A buffer unit for temporarily storing a substrate includes a housing having a space for storing a substrate therein, one or more slots disposed within the housing for placing a substrate thereon, and a holding unit disposed at a bottom portion of the housing, having a flat and non-inclined top surface, and comprising a built-in wireless charging module. A substrate type sensor is stored at the holding unit.

Abstract: An apparatus of tilting a seat cushion of a vehicle, includes a tilting motor, a pinion gear, a sector gear, and a tilting link which perform the tilting operation of the seat cushion and exert a binding force in a tilted state of the seat cushion and are provided to be connected to both of one side and the other side of a seat cushion frame, and has two sector gears positioned on left and right sides and connected to each other by a connection bar so that, by strengthening a binding force of the front portion of the seat cushion, it is possible to secure the safety of passengers in the event of a collision.

Abstract: Provided is a jetting driver that can be used for various types of heads with minimal changes. The jetting driver includes: an image board receiving raw image data and generating image data by transforming the raw image data into a form suitable for a type of heads used; and an interface board physically separated from the image board, receiving the image data, and transmitting the image data to the heads through a plurality of channels.
