  • Patent number: 10627549
    Abstract: Substrates with lenses having lenses disposed therein are aligned with high accuracy. A stacked lens structure has a configuration in which substrates with lenses having a lens disposed on an inner side of a through-hole formed in the substrate are direct-bonded and stacked based on an alignment mark. The alignment mark is formed simultaneously with the through-hole. The present technique can be applied to a camera module or the like in which a stacked lens structure in which at least three substrates with lenses including first to third substrates with lenses which are substrates with lenses in which a through-hole is formed in the substrate and a lens is formed on an inner side of the through-hole is integrated with a light receiving element, for example.

  • Patent number: 10627258
    Abstract: In a related-art resolver, a front and a back of a stator core cannot be distinguished, and it is difficult to mass-produce the resolver while matching directions of shear drops and burrs. Thus, assembly accuracy of the resolver is degraded. Further, productivity and assembling ability are degraded because electromagnetic steel sheets are laminated by rotary lamination. The present invention provides a resolver including: a resolver stator including: a stator core formed of electromagnetic steel sheets, which have teeth, and are laminated without rotary lamination; a one-phase excitation winding; and two-phase output windings; and a resolver rotor arranged to be opposed to the resolver stator, in which the stator core has marks which enable distinction of a rolling direction of the stator core and distinction of a front and a back of the stator core.
