Publication number: 20240075665Abstract: A molded resin product includes a plurality of protrusions formed in a predetermined region. A histogram indicating a height distribution of the plurality of protrusions has two peaks having a boundary height as a boundary therebetween. In a case where protrusions having height equal to or smaller than the height Hx are first protrusions and protrusions having height larger than the boundary height are second protrusions among the plurality of protrusions, an arithmetic mean curvature of the first protrusions is smaller than an arithmetic mean curvature of the second protrusions.Type: ApplicationFiled: November 13, 2023Publication date: March 7, 2024Inventors: Toshimitsu Nagoya, Kei Oikawa, Makoto Kojima, Takahiro Suzuki, Mao Mukaida

Patent number: 9016917Abstract: An electronic device includes a housing, a first light guide plate, a second light guide plate, and a first adhesive member. A first hole in position to a first light-emitting source and a second hole in position to a second light-emitting source are formed on the housing. The first light guide plate has a first projection to be inserted into the first hole. The second light guide plate has a main-body plate portion to be superposed on the first light guide plate with the first projection penetrating therethrough and a second projection to be inserted into the second hole. The second light guide plate blocks out the light of the first light-emitting source with the main-body plate portion. The first adhesive member is inserted between the second light guide plate and the housing, and attaches the main-body plate portion to the housing.Type: GrantFiled: April 16, 2013Date of Patent: April 28, 2015Assignee: Fujitsu LimitedInventors: Kyoko Fujita, Jun Hata, Kei Kojima, Chikara Kobayashi

Patent number: 8886257Abstract: An electronic device includes a housing, a display module, and a touch panel. On the housing, an opening is formed. The display module is fixed to the inside of the housing in such a way that a display surface faces the side of the opening. The touch panel is placed to be opposed to the display surface of the display module via a first elastic member placed on the display surface of the display module, and is fixed to the housing via a second elastic member placed on the housing. Hardness of the first elastic member is higher than that of the second elastic member.Type: GrantFiled: April 22, 2013Date of Patent: November 11, 2014Assignee: Fujitsu LimitedInventors: Tomohiro Butsusaka, Kei Kojima, Chikara Kobayashi, Masahiko Ina, Shigehiro Fujii
