  • Publication number: 20190162339
    Abstract: A metal seal can be crushed evenly without forming wrinkles and scratches due to sliding against first and second flat surfaces. The seal comprises a first/second end surface arranged to face the first/second flat surface, respectively. The first end surface comprises a first convex part having a curved or flat surface that contacts the first flat surface, and a first projection that is formed shifted in a radial direction from the first convex part and has a ridge line that contacts the first flat surface. Prior to deformation, when the second end surface contacts the second flat surface and the first flat surface is separated from the first end surface, a point where a vertical distance between the first convex part and the second flat surface is the greatest and the ridge line are located on the same surface that is parallel to the first flat surface.

  • Patent number: 9154578
    Abstract: In a communication terminal device, in a case where the arrangement of the windows is changed in a list screen, an overhead screen is initially displayed, in which the list screen is overviewed, and the arrangement of the windows is subsequently changed in the overhead screen, and a magnified screen (original screen) of the overhead screen, in which the arrangement of the windows has been changed, is displayed last, as described in the foregoing. By displaying a magnified image, it is possible to make windows better visible in a small display area of a mobile phone. Also, in a case where a window exists that cannot be displayed in a magnified screen, by displaying an overhead screen, it becomes possible for a user to recognize a fact that a window that cannot be displayed exists in a magnified screen, and also recognize a position of the window.

  • Patent number: 9112994
    Abstract: The environment around mobile phone handset 10 is judged according to the number of other mobile phone handsets present near mobile phone handset 10 and the registration status of the nearby telephones. Then, the display sequence of function names on a function selection screen is changed according to the environment. As a result, functions deemed likely to be selected by the user based on the environment surrounding mobile phone handset 10 may be displayed at positions where they may be selected with fewer operations. In this way, the number of operations required of the user for selecting any of multiple functions may be reduced.

  • Patent number: 9001156
    Abstract: An information-processing device comprises: a display control that controls display positions of first and second information images in a display area of a display means for displaying an image, instructions are received for causing the first information image to move in a given direction. A display control executes a first process that, during a period in which the instruction is received, causes the first information image to move and a second process that, in a case where the first information image comes into contact with the second information image as a result of the movement caused by the first process and is further moved after the contact, causes the second information image to move in a direction different from the direction of movement of the first information image, such that the second information image does not overlap the first information image.

  • Patent number: 8984443
    Abstract: An information processing device displays in a display area a key image indicating an associated key to which a process is allocated as a soft key. In the information processing device, a key to which a process is allocated can be changed. The information processing device changes what is displayed based on the display mode. For example, if processes are allocated to a key, the information processing device displays an associated key image. If the user desires to change the orientation of the device, the key and associated key image and allocated process can be changed.
