Publication number: 20240081404Abstract: Provided is a heater for an aerosol-generating device including a first electrically conductive pattern configured to perform heating and a second electrically conductive pattern arranged in parallel with the first electrically conductive pattern. The first electrically conductive pattern and/or the second electrically conductive pattern may include a material having a relatively small resistance temperature coefficient. Accordingly, a temperature increase rate of the heater may be greatly improved.Type: ApplicationFiled: January 13, 2022Publication date: March 14, 2024Applicant: KT&G CORPORATIONInventors: Jong Seong JEONG, Gyoung Min GO, Hyung Jin BAE, Jang Won SEO, Chul Ho JANG, Min Seok JEONG, Jin Chul JUNG

Patent number: 8180416Abstract: A sliding-type mobile communication terminal having a first housing and a second housing opened or closed by means of a sliding movement in a longitudinal direction of the first housing, The terminal includes a spring module adapted to provide a sliding force, along the longitudinal direction, for closing of the second housing within a predetermined range of distance, and for providing the sliding force in an opposite direction for opening of the second housing beyond the predetermined range of distance. The spring module includes link bars rotatably coupled in one end onto the first housing, coil springs supported by one end of the link bar and coupled to enclose the link bar, and a slider slidably coupled to the link bar to be acted upon by an elastic force from the coil spring. The coil springs implement a semi-automatic sliding opening/closure of the second housing.Type: GrantFiled: March 5, 2008Date of Patent: May 15, 2012Assignee: Samsung Electronics Co., LtdInventors: Tae-Keon Park, Chul-Ho Bae, Tae-Ha Chang, Su-Yong Jung

Patent number: 7433723Abstract: A spring module in a sliding-type portable terminal has a first housing and a second housing. In a predetermined portion of the length of the first housing, the spring module applies an elastic force in a direction in which the second housing slides to cover the first housing. In the remaining portion of the length of the first housing, the spring module applies the elastic force in a direction in which the second housing slides to expose the first housing. As a consequence, the elastic force generated by the spring module provides for semi-automatic opening/closing of the sliding-type portable terminal.Type: GrantFiled: September 17, 2004Date of Patent: October 7, 2008Assignee: Samsung Electronics Co., LtdInventor: Chul-Ho Bae

Publication number: 20080158832Abstract: A sliding-type mobile communication terminal having a first housing and a second housing adapted to allow the first housing to be opened or closed by means of a sliding movement on the first housing in a longitudinal direction of the first housing. The terminal includes a spring module adapted to provide a sliding force, along the longitudinal direction of the first housing, for allowing closing of the second housing within a predetermined range of distance, and for providing the sliding force in an opposite direction for allowing opening of the second housing beyond the predetermined range of distance. The spring module includes link bars rotatably coupled in one end onto the first housing, coil springs supported by one end of the link bar and coupled to enclose the link bar, and a slider slidably coupled to the link bar to be acted upon by an elastic force from the coil spring. The terminal uses the elasticity in coil springs to implement a semi-automatic sliding opening/closure of the second housing.Type: ApplicationFiled: March 5, 2008Publication date: July 3, 2008Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Tae-Keon Park, Chul-Ho Bae, Tae-Ha Chang, Su-Yong Jung

Publication number: 20050041148Abstract: Disclosed herein is a camera lens assembly for portable wireless terminals. The camera lens assembly includes a first lens housing rotatably attached to a portable wireless terminal so that the first lens housing can be rotated about a first rotating axis, and a second lens housing rotatably attached to one end of the first lens housing so that the second lens housing can be rotated about a second rotating axis extending perpendicularly to the first rotating axis. The second lens housing has a camera lens mounted therein. The camera lens can be independently rotated about two rotating axes extending transversely to one another, whereby a picture-taking operation can be effectively carried out in various directions.Type: ApplicationFiled: March 29, 2004Publication date: February 24, 2005Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventor: Chul-Ho Bae
