  • Patent number: 8328395
    Abstract: A light emitting apparatus emits light emitted from a light emitting element (200) mounted on a substrate (300) via a luminous flux control member (100). The luminous flux control member (100) has a bottom surface section (101) opposite to the substrate (300), an input surface section (106) for causing the light emitted from a light emitting element (200) to enter inside the input surface section (106), a light control output surface section (102) for refracting the light having entered from the input surface section (106) and outputting the light outside, and two or more leg sections (103) are formed to project outward from the bottom surface section (101) inside a circle with a circumference on which a position where the amount of light reflected by the light control output surface section (102) and yet reaching the bottom surface section (101) peaks is located, and attached to the substrate (300).

  • Patent number: 8327488
    Abstract: An actuator allows miniaturization by realizing back-and-forth rotating motion of, for example, an electric brush without a drive transmitting mechanism which constitutes a separate entity from a drive source. In a movable body (160) of this actuator (100), an outer yoke (110) is provided with inner wall planes (112a and 113a) located opposing each other spaced a predetermined interval apart and magnets (121 and 123) of different magnetic poles opposing each other in the inner walls planes (112a and 113a). The movable body (160) has a center yoke (140) located between the magnets (121 and 124) through air gaps. The movable body (160) is provided with a shaft (150). The fixed body (180) has a coil (170) which is located in the air gaps and which circles the center yoke (140). The fixed body (180) movably supports the movable body (160) through elastic bodies (190).

In a movable body (110) of this actuator (100), an outer yoke (150) is provided with sidewalls (152 and 153) located opposing each other spaced a predetermined interval apart. A magnet (160) is provided in the outer yoke (150) through a non-magnetic body (170) and has different magnetic poles located opposing to the opposing inner wall planes of the outer yoke (150) through the air gaps. The movable body (110) is provided with a shaft (180). The fixed body (120) has a coil (128) which is located in the air gaps and which circles the magnet (160). The fixed body (120) movably supports the movable body (110) through elastic bodies (130).

  • Patent number: 8172587
    Abstract: The card connector can adequately detect the state in which an electronic device such as a memory card to be inserted and removed is fitted, and saves the footprint for mounting the card connector. With this card connector, a card detection switch detects a state in which a memory card is fitted in an accommodating part of a housing through an insertion slot. The card detection switch has movable terminals and fixed terminals, and the movable terminals each have a card contact part which is displaced by being pressed by the memory card to be inserted, and a movable contact part which is displaced in a same direction as a direction in which card contact part is displaced following displacement of the card contact part. The fixed terminals are each arranged in the housing to project in a direction to interest the direction in which the movable contact part is displaced, and is slid against by the movable contact part when the movable contact part is displaced.

  • Patent number: 8153919
    Abstract: A membrane switch can attach an elastically deformable dome to a board in a reliable manner such that the dome is not detached even if a fixing sheet is made thinner and smaller and therefore has a smaller footprint. This switch has: a dome (110) that is formed projecting toward the surface and that is dented opposite toward the back surface by elastic deformation; and a flexible fixing sheet (120) that has a back surface of an adhesive face pasted to the entire face of the surface of the dome (110). The fixing sheet (120) fixes the dome (110) in a predetermined position of a board (4) by means of a stretching part (122) which stretches radially outer to the dome (110), from an outer rim (112) of the dome (110), in a direction virtually orthogonal to a direction in which the dome (110) projects.

  • Patent number: 8148213
    Abstract: A method for manufacturing a biosensor includes forming a laminate of a first silicon oxide film and a polysilicon film on one surface of a silicon substrate; forming a second silicon oxide film on the other surface of the silicon substrate; forming a source electrode, a drain electrode, and a channel on the first silicon oxide film, the channel connecting the source electrode and the drain electrode; and removing the polysilicon film.
