Abstract: A shutoff valve structure of a liquefied petroleum injection (LPI) engine includes an operation valve disposed within a pump housing in a fuel pump and configured to allow or block the flow of fuel from the fuel pump. The shutoff valve structure includes an extension including a knob disposed outside the pump housing and connected to the operation valve by being extended into the pump housing. The operation valve is operable by the knob.

Abstract: A window includes: a folding part foldable around a virtual folding axis extending in a first direction, and first and second non-folding parts spaced apart from each other in a second direction perpendicular to the first direction with the folding part therebetween. A plurality of groove patterns extending in the first direction and arranged in the second direction are defined in the folding part. The folding part includes a first part adjacent to the folding axis, a third part adjacent to one of the first and second non-folding parts and a second part between the first part and the third part. widths of the first to third parts in the second direction are the same. A volume of the first part is greater than a volume of the second part, and the volume of the second part is greater than a volume of the third part.

Abstract: The present invention relates to: a method for producing a metallocene-supported catalyst, the method including (1) a step of producing a reaction solution 1 by reacting one or more metallocene compounds with one or more co-catalyst compounds, (2) a step of performing supporting by mixing a support with the reaction solution 1, (3) a step of producing a reaction solution 2 by reacting one or more metallocene compounds with one or more co-catalyst compounds, and (4) a step of mixing the reaction solution 2 with the supporting material of the step (2); and a metallocene-supported catalyst produced by the same.
