A camera module package comprises a housing having a lens section mounted therein; a circuit board having a window through which light transmitted through the lens section of the housing passes; an image sensor that is flip-chip bonded to a lower surface of the circuit board; and an impact absorbing member attached to an upper surface of the circuit board, of which the side surface serves as a coupling guide which is coupled to an inner periphery of the housing.

A photodiode array 1 has a plurality of photodetector channels 10 which are formed on an n-type substrate 2 having an n-type semiconductor layer 12, with a light to be detected being incident to the plurality of photodetector channels 10. The photodiode array 1 comprises: a p−-type semiconductor layer 13 formed on the n-type semiconductor layer 12 of the substrate 2; resistors 4 each of which is provided to each of the photodetector channels 10 and is connected to a signal conductor 3 at one end thereof; and an n-type separating part 20 formed between the plurality of photodetector channels 10. The p−-type semiconductor layer 13 forms a pn junction at the interface between the substrate 2, and comprises a plurality of multiplication regions AM for avalanche multiplication of carriers produced by the incidence of the light to be detected so that each of the multiplication regions corresponds to each of the photodetector channels. The separating part 20 is formed so that each of the multiplication regions AM of the p−-type semiconductor layer 13 corresponds to each of the photodetector channels 10.

An inline-ready method of finishing the surface of a long material (W) capable of preventing any environmental problem from occurring and the mechanical properties of the long material from deteriorating, comprising the steps of holding the long material (W) by two or more elastic endless belts (1) with a specified force, rotating the elastic endless belts (1) in the same direction as or in the reverse direction to the moving direction of the long material by moving the long material (W) and increasing or decreasing the rotating speed of the elastic endless belts (1) more than or less than the moving speed of the long material, and loading powder and granular grinding material (S) between the elastic endless belts (1), characterized in that the grinding material (S) is moved relative to the long material (W) to rub the grinding material (S) against the long material (W) so as to finish the surface of the long material (W).

Each point light source includes an overhang projecting perpendicularly to a light emitting surface from one side of the light emitting surface, and the overhang has its main surface made in contact with a light outgoing surface of a light guide plate with the light emitting surface facing a light incident surface of the light guide plate. Engagement of the overhang with the light outgoing surface of the light guide plate prevents a displacement of the light emitting surface of the point light source and the light incident surface of the light guide plate even when the light guide plate suffers from deformation such as warpage. Even if a displacement occurs, the presence of the overhang reflects leaked light to guide it to the light incident surface of the light guide plate.
