Abstract: An imaging module includes an imaging chip including a micro-lens guiding incident light and an imaging element in a semiconductor substrate and converting the incident light into an electric signal, and a polarizing glass chip including a polarizing filter glass having a polarizer determining a polarization direction of the incident light arranged on a transparent substrate such that the polarizer faces the micro-lens and a spacer member connected to the polarizing filter glass to adjust a gap between the polarizer and the micro-lens of the imaging chip. In the imaging module, a melt-bonding surface of the spacer member is melt-bonded to the semiconductor substrate such that the polarizer of the polarizing glass chip and the micro-lens of the imaging chip are arranged close to each other via the gap, and the imaging element and the micro-lens of the imaging chip are sealed by the polarizing glass chip.

Abstract: A movable device includes: a mechanism configured to drive a movable portion, the mechanism including: a gear including a first protrusion; and a cam in contact with the movable portion; and a driver to drive the mechanism, the driver including: a second protrusion to engage with the first protrusion; and an actuator to cause the second protrusion to reciprocate in response to application of voltage or electric current, to rotate the gear in a predetermined direction, to rotate the cam with the rotation of the gear to drive the movable portion. The first protrusion has a shape in which a downstream portion in the predetermined direction is lower in a direction perpendicular to the predetermined direction than an upstream portion. The second protrusion has a shape in which a downstream portion in the predetermined direction is higher in the direction perpendicular to the predetermined direction than an upstream portion.
