  • Patent number: 9752477
    Abstract: A honeycomb structure including a honeycomb structure body, first plugging portions, and second plugging portions. The honeycomb structure body has a porous partition wall. The first plugging portions are disposed at an outflow side end face of inlet cells and an inflow side end face of outlet cells. The inlet cells are the predetermined cells of the honeycomb structure body. The outlet cells are the residual cells of the honeycomb structure body. The second plugging portions are not fired. The first plugging portions form a checkered pattern at the inflow side end face and the outflow side end face. The number of the second plugging portions is within 3% of the number of cell open ends where the first plugging portions are not formed, on both end faces of the honeycomb structure body.

  • Patent number: 7403776
    Abstract: When electronic mail transmitting operation is performed, it is checked whether the standby mode is the digital mode. If the standby mode is not the digital mode, processing for changing the standby mode from the analog mode to the digital mode is executed. When the standby mode is changed to the digital mode, the electronic mail is transmitted through a digital channel. If the standby mode cannot be changed to the digital mode, the transmission electronic mail is stored in a memory, and message hold transmission control is executed afterward.

  • Patent number: 7388574
    Abstract: A pointing device is provided which facilitates the assembly, achieves downsizing and has a long life. Magnetic sensors 21 are placed symmetrically two by two along an X axis and Y axis on a printed circuit board 24. A switch 28 is placed on a silicone resin 23 side surface of the printed circuit board 24 to provide a switch function achieved by depressing a magnet cover 25 toward the magnet 22. The pointing device, a device for outputting coordinate values of an input point, can not only output the coordinate values, but also make a decision by the switch function. A silicone resin 23 is easy to deform caused by an external force, and returns its initial state without the applied external force as soon as the external force is removed.
