Abstract: Imaging devices and ranging devices are disclosed. In one example, an imaging device includes a semiconductor substrate, a first pixel array, a second pixel array, and a control unit. In the first pixel array, a first light receiving pixel on the semiconductor substrate has a stacked structure of a first electrode, a photoelectric conversion layer, and a second electrode (80). It photoelectrically converts light in a first wavelength region including the visible light region. In the second pixel array, a second light receiving pixel is provided at a position overlapping the first light receiving pixel in a thickness direction of the semiconductor substrate. It photoelectrically converts light in a second wavelength region including the infrared light region. The control unit drives and controls the second pixel array based on a signal photoelectrically converted by the first pixel array.

Abstract: A gravity door hinge in which a cam is inserted non-rotatably into the lower half of a socket provided in a fixed member, the upper end of an axial rod is inserted non-rotatably into an axial bore hole provided in a rotational member, a cam follower is fitted rotatably around the middle of the axial rod by inserting the axial rod through a central hole bored in the cam follower, the lower half of the axial rod is inserted rotatably into an axial hole formed by hollowing out the center of the cam, the cam follower is fitted rotatably into the upper half of the socket, on top of the cam housed in the lower half of the socket so that an inclined cam surface formed on the lower end of the cam follower comes into close contact with an inclined cam surface formed on the upper end of the cam, and the base of the socket is completely closed.
