  • Patent number: 9888227
    Abstract: Provided is a highly reliable imaging module that can easily carry out optical axis adjustments and focus adjustments while assuring required light shielding performance, and in which malfunctions do not easily occur in solder junctions and the like for imaging elements even under severe temperature environments. An imaging module has, in addition to a lens holding member (10), an imaging element (25), and a substrate (30) on which the imaging element (25) is mounted, a shielding member (40) that is for preventing extraneous light from entering the imaging surface of the imaging element (25) and on which a ring-shaped or notched ring-shaped protrusion (51) for shielding is provided. The shielding member (40) is held between the lens holding member (10) and the substrate (30) without the protrusion (51) for shielding coming into contact with another member.

  • Patent number: 9456199
    Abstract: Although a conventional method can eliminate a mounting position deviation when left and right camera units only are taken into consideration, a problem is posed that deviation again occurs due to poor machining precision and assembly precision at the mounting surface between a camera unit and a member when a camera unit is mounted to a stay. According to this invention, mounting surfaces for mounting left and right imaging elements to a stay are provided to directly position left and right imaging elements to the stay, whereby built-up tolerance between components is reduced and the positional mounting precision between imaging elements is improved.

  • Publication number: 20160219896
    Abstract: The present invention discloses a method of manufacturing porous granules, a porous granule obtained by the method, a lipid-containing granule and a method of manufacturing thereof, and a food containing the lipid-containing granules and a method of manufacturing thereof. The porous granule of the present invention is bigger than the granule manufactured by the spray drying method, has high solubility, is easily obtained (porous structure can be easily formed), and has enough hardness. In addition, drying time and drying cost can be reduced because an amount of water to be dried can be reduced. The porous granule can be obtained by mixing a powder whose solubility is at most 100 g per 100 mL of water at 20° C., with water and drying a mixture under reduced pressure to obtain the porous granules having loose bulk density of at least 0.30 g/mL, having porous structure, and capable of absorbing lipids.
