Abstract: A light receiving element is comprised of a light sensitive surface on a semiconductor substrate and a positive electrode (anode), a negative electrode (cathode), a mounting precision test mask, a conductive electrode wire, and solder resist on the same substrate surface. A metal thin film, a mounting alignment mark, and a mounting precision mark window are provided on the back side of the substrate. Two or more electrode surfaces having either the anode or the cathode used as the common electrode are provided. The light sensitive surface is positioned approximately in the center between these two electrode surfaces.

High precision mounting is also obtained when mounting light receiving element arrays. This type of light receiving element can be precisely positioned and bonded by solder bumps to a substrate having an optical fiber fitted in the V groove.

This device operates in the following way: a piezo-electric element transmits the pressure generated by its vibration first to the pressure transmitting medium of a non-solid matter; through this medium, the pressure is transmitted to the passive vibrating means being in contact with the ink to be projected, and facing the orifice through which ink is projected, thereby vibrating this vibrating means, and by the pressure generated by the vibration, ink is projected through the orifice. With such a structure, the assembling work of this device is easy; uniform projection characteristics are achieved, and moreover, the problem of air suction with resultant projection failure is eliminated.
