Patent number: 11988228Abstract: Air compressor for a vehicle having improved internal cooling efficiency by ensuring a circulation flow of compressed air for internal cooling and allowing the compressed air to sufficiently flow. The air compressor comprises: a housing with a compression unit for introducing and compressing air from outside; a motor unit which includes a rotor and a stator, and drives the compression unit to rotate according to the rotation of the rotor; a bearing unit supporting the rotor to be rotatable; a cooling circulation flow path formed inside the housing for moving, in an axial direction, some of the air compressed in the compression unit and circulating the air to the compression unit; and a bypass flow path which receives some of the air passing through the cooling circulation flow path and bypasses a partial region of the bearing unit to join the cooling circulation flow path.Type: GrantFiled: September 29, 2020Date of Patent: May 21, 2024Assignee: Hanon SystemsInventors: Gun Woong Park, Chi Yong Park, Jong Sung Lee, Kyu Sung Choi

Patent number: 11213029Abstract: The present invention relates to a composition for controlling plant diseases containing a limonene derivative as an active ingredient. In the present invention, the limonene derivatives have an effect of inhibiting the growth of Xanthomonas oryzae pv. Oryzae (Xoo), which is a pathogen mediating bacterial leaf blight, and Magnaporthe oryzae, which is a pathogen mediating rice blast, and it was confirmed in an experiment with respect to inhibition using volatility (i.e., in a state not being in direct contact with Xoo or M. oryzae) that the limonene derivatives have a growth inhibitory effect. Accordingly, the limonene derivatives have an inhibitory effect against the growth of Xoo and thus they can be effectively used as a composition for controlling plant diseases.Type: GrantFiled: June 7, 2018Date of Patent: January 4, 2022Assignee: KOREA ATOMIC ENERGY RESEARCH INSTITUTEInventors: Sungbeom Lee, Gun Woong Lee, Kwangwoo Jung, Byung Yeoup Chung, Seungsik Lee, Jin-Hong Kim, Hyoungwoo Bai, Yong-Dae Park

Publication number: 20090312216Abstract: The present invention relates to a photoresist stripper composition for removing the photoresist in the manufacturing process of the semiconductor device. More particularly, the photoresist stripper composition comprises 3-20 wt % of hydrazine hydrate or amine compound; 20˜40 wt % of polar solvent; 0.01-3 wt % of corrosion inhibitor selected from the group consisting of imidazoline derivative, sulfide derivative, sulfoxide derivative, aromatic compound or aromatic compound with hydroxyl group; 0.01-5 wt % of monoalcohol compound of C2-C10; and 40-70 wt % of deionized water. The photoresist stripper composition for manufacturing the semiconductor can remove the photoresist film thermoset by hard bake, dry etching, ashing or ion implantation and denatured by the metallic by-product etched from the bottom metallic film in said process at low temperature easily and quickly, and minimize the corrosion of the bottom metallic wiring in the removing process of the photoresist.Type: ApplicationFiled: August 5, 2006Publication date: December 17, 2009Applicant: TECHNO SEMICHEM CO., LTD.Inventors: Hyun Tak Kim, Seong Hwan Park, Jung Hun Lim, Sung Bae Kim, Chan Jin Jeong, Kui Jong Baek, Woong Hahn, Sang Won Lee, Gun-Woong Lee
