  • Patent number: 10844251
    Abstract: Provided is a method of producing a pressure-sensitive adhesive containing a cured product of a curable composition containing a crosslinkable silicon group-containing organic polymer and an adhesion-imparting resin as a pressure-sensitive adhesive layer; curing of the curable composition does not proceed when heated during production, i.e., the curable composition has excellent stability when heated, and the crosslinking reaction of the curable composition proceeds by some sort of trigger. The pressure-sensitive adhesive contains, as a pressure-sensitive adhesive layer, a cured product of a curable composition containing (A) a crosslinkable silicon group-containing organic polymer, (B) an adhesion-imparting resin, (C) a Si—F bond-containing silicon compound, and (D) a photobase generator.

  • Patent number: 8248540
    Abstract: In a broadcast signal receiving apparatus, a remote controller has, as one of a plurality of buttons thereof, a state changing button for instructing to change a source to be reproduced by a main body. The main body or the remote controller has a memory storing a first state changing table indicating an order in which the source is changed. When the state changing button is operated, if the broadcast signal is being received by the tuner portion and reproduced as the source, the main body performs state change such that the first source in the first state changing table is specified as the source to be reproduced by the main body.

  • Publication number: 20090316017
    Abstract: An imaging apparatus is so configured that the imaging apparatus and an external electronic device are connected, and when the imaging apparatus is in a power-save mode state, if a predetermined button on an external electronic device-use remote controller is depressed, the imaging apparatus is shifted from the power-save mode to a normal activation mode, and respective thumbnail images of a still image file and/or a moving image file stored in the imaging apparatus are multi-displayed on the external electronic device. Therefore, a user is able to immediately confirm what images are stored in the imaging apparatus with a simple manipulation, and thus, convenience is provided.
