Abstract: The present disclosure relates to a transmission of an agricultural work vehicle, the transmission comprising: a pre-shift part for performing speed shifting on driving transmitted from an engine of an agricultural work vehicle; a clutch part connected to the pre-shift part so as to selectively output driving transmitted from the pre-shift part; an adjusting part connected to the clutch part so as to perform speed shifting on driving transmitted from the clutch part; and a subsequent shift part connected to the adjusting part so as to perform speed shifting on driving transmitted from the adjusting part.

Abstract: Provided is an aerogel blanket and a method for producing the same, wherein a catalyzed sol is sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalyzed sol can be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.

Abstract: An air pocket module (10) inserted into an air mattress (1) includes a plurality of air pockets (100), each of which has a hollow defined therein to be expanded due to air inflow or contracted due to air outflow, and a lower plate (110) coupled below the air pockets (100) to shield the hollow of the air pocket (100). The air pocket (100) includes a top surface part (1100) provided in a regular n-polygonal shape (n is an even integer of 6 or greater) when viewed in a plan view, a connection part (1200) connected to the top surface part (1100), side surface parts (1300), each of which has one end connected to the connection part (1200) to extend downward and the other end connected to the lower plate (110), a side surface part connection part (1400).

Abstract: Provided is an aerogel blanket and a method for producing the same, wherein a catalyzed sol I sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalyzed sol can be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.

Abstract: An embodiment roof assembly for a vehicle includes a roof panel including a core, an upper skin attached to a top surface of the core, and a lower skin attached to a bottom surface of the core, a face sheet disposed above the roof panel, and a foam layer interposed between the roof panel and the face sheet.

Abstract: Apparatus and method for measuring an aerial image whereby influences of various defects existing on patterns formed on a photomask as well as the surface of the photomask substrate can be inspected. The aerial image measuring apparatus includes an optical transmitting device, an optical reflecting device and an aerial image forming device. The optical reflecting device includes a beam splitter and a reflecting mirror. The reflecting mirror switches the path of light so that the light transmitted along the reflected light path is irradiated to the surface of the photomask on which the patterns are formed. According to an aerial image measuring method of the present invention, either transmitted light or reflected light is selected for analysis, the selected light is converted into an electrical signal to form an aerial image, and the aerial image is measured.

Abstract: A method of projection exposure utilizing a mask including a step of exposing an object by utilizing a transparent mask substrate of which the upper surface is slanted at a predetermined angle from a direction perpendicular to the light path and an opaque film pattern is formed at regular intervals on a lower surface of the mask substrate so that the phase difference between adjacent mask patterns occurs due to the slanted mask substrate, thereby reducing the minimum pitch available for pattern formation without a shorter-wavelength light source and without increasing NA by reducing the frequency difference .delta.v to the pitch d of the mask in a given wavelength of a light source and NA.
