  • Patent number: 10162425
    Abstract: An input device includes a touch panel incorporating a switch electrode region, and an actuator. The switch electrode region includes a switch electrode and a ground electrode disposed side by side with the switch electrode. The actuator includes a push button having an operation surface, an elastic body, a conductor, and a facing surface.

  • Patent number: 7528783
    Abstract: An antenna including a rectangular ground plane, a feed point disposed in a vicinity of a corner of the ground plane, an antenna element coupled to the feed point, and a parasitic element coupled to the ground plane. In this antenna, the shortest length from the feed point to a distant narrow side of the ground plane and a shortest length from the feed point to a tip of the parasitic element via the ground plane have substantially the same electrical length. Such a configuration can correspond to a small and thin size and reduce SAR easily.

  • Publication number: 20080019254
    Abstract: A laser beam emitted from a light source is divided into a main beam and two sub-beams by a diffraction grating. A filter is arranged between a collimator lens and an objective lens. A filter unit is arranged in a predetermined pattern in the filter. The filter unit gives a maximum transmittance or a maximum reflectance at an incident angle at which the laser beam is incident in a parallel light state. The filter unit is formed in a pattern in which at least the laser beam reflected from a layer except a recording layer of an irradiation target is prevented from entering a sub-beam sensor pattern.
