  • Patent number: 11940347
    Abstract: A pressure sensor has a stem in which a pressure introduction hole into which a pressure medium is introduced and a diaphragm deformable according to the pressure of the pressure medium are formed, and a strain detecting element which is arranged on the diaphragm via an insulating film and being configured to output a detection signal according to the deformation of the diaphragm. The strain detecting element is configured to have a portion made of polysilicon. A low doping layer having a higher electrical resistivity than polysilicon and a higher crystallinity than the insulating film is arranged between the insulating film and the strain detecting element.

  • Patent number: 9753207
    Abstract: A light guide plate having light-emitting-side unit optical shapes arranged on a light emitting surface in a direction perpendicular to a light guide direction and a thickness direction of the light guide plate. The optical shape extends in the light guide direction and has a groove shape recessed in the light emitting surface, and a bottom of the groove is formed on a surface which is concave toward the back surface side. Inclined surfaces which are inclined from an edge portion toward the bottom side are formed in two end portions of the concave surface in an arrangement direction. When a width of the optical shape in the arrangement direction is W21, a maximum inclination angle ? of the inclined surface relative to the light emitting surface satisfies 20°???45°, and a radius of curvature r of the concave surface satisfies r?W21/(4×sin ?).

  • Patent number: 9239420
    Abstract: A light guide plate 13 has a number of back surface-side unit optical structures 131 arranged in a back surface 13d along a light guide direction. Each back surface-side unit optical structure 131 is tapered in a direction away from a light exit surface 13c, and has a first inclined surface 132 lying on the light entrance surface side, a second inclined surface (133) lying opposite the first inclined surface and which totally reflects at least part of incident light, and a top surface region 134 lying between the first inclined surface 132 and the second inclined surface 133, and located farthest from the light exit surface 13c. The top surface regions 134 each include a plurality of surfaces 134a to 134d which are parallel to the light exit surface 13c and have different heights “h” in the direction away from the light exit surface 13c.

  • Patent number: 6725027
    Abstract: A multipath noise reducer detects and removes the individual noise spikes occurring in an interval of multipath noise, thereby reducing the multipath noise with minimal distortion of the audio output signal. The multipath noise spikes are detected by comparing a rectified signal with a threshold signal derived from the rectified signal. When the multipath noise reducer is used in an FM stereo radio receiver, stereo separation may also be controlled according to the detection of multipath noise.
