Patent number: 10252213Abstract: Provided is a dehumidification apparatus with good energy efficiency. A moisture absorbing material (polymeric moisture absorbing material 24), which absorbs moisture and swells at a temperature not higher than a predetermined temperature sensitive point, while shrinking and releasing condensed water at a temperature higher than the temperature sensitive point as a result of phase transition, is formed so as to be divided into a plurality of segments which are made apart from each other during dehydration. A rotation motor (21) is used to move the moisture absorbing material (polymeric moisture absorbing material 24) between a moisture absorption region (14a) and a dehydration region (14b). In the dehydration region (14b), the moisture absorbing material (polymeric moisture absorbing material 24) is heated by the heater (25).Type: GrantFiled: August 27, 2015Date of Patent: April 9, 2019Assignees: SHARP KABUSHIKI KAISHA, THE SCHOOL CORPORATION KANSAI UNIVERSITYInventors: Yoshihiro Uramoto, Nobuki Sakikawa, Takashi Miyata

Patent number: 7822449Abstract: In a front surface leather portion of a cover 10, there are formed a display surface opening portion 14 for exposing a display screen of a display of a mobile communication terminal 90, an operating surface opening portion 15 for exposing an operating surface of an input device of the terminal 90, and a fitting opening portion 16 for fitting this cover 10 to the terminal 90. Accordingly, even when the cover 10 is fitted, it is possible for the user both to check the display screen of the terminal 90 from the portion 14 and to actuate the input device of the terminal 90 from the portion 15. Due to this, it is possible to implement a cover for a mobile communication terminal which, along with maintaining a good operating feeling and serving as cushioning material in the case of shock, can also impart a soft texture and a sense of high quality.Type: GrantFiled: April 30, 2007Date of Patent: October 26, 2010Assignee: Vodafone K.
