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: The invention relates to a dielectric filter for mounting to a printed wiring board wherein the edges of the filter's electrodes are covered with a protective film to prevent the peeling of edges of electrodes. The dielectric filter is a dielectrics (1) having a through hole (2) extending from its top to bottom face, an external electrode (3a) disposed on the outer face of the dielectrics (1) except for the top face, an internal electrode (3b) disposed inside the through-hole (2), island-like input/output electrodes (6) which are disposed on the outer side face of said dielectrics (1) and surrounded by a non-electrode portion (5) of the external electrode (3a). An electrode protection film (8) covers an outer edge of said input/output electrode (6), the non-electrode portion (5) of the external electrode (3a) disposed around the input/output electrode (6), and an inner edge of the external electrode (3a) contacting the non-electrode portion (5).

Abstract: Antenna sharing device used for a communications system such as a land mobile radiotelephone which has a transmitting frequency and a receiving frequency that are different from each other, and which commonly uses the antenna transmission and reception. The bands of transmission and reception of the antenna sharing device are each divided into half and are switched into a pair of sending side low-pass filter and a receiving side low-pass filter and a pair of sending side high-pass filter and a receiving side high-pass filter by a switching device, whereby the band widths of transmission and reception are narrowed and the isolation point is increased between the transmission and reception.
