摘要:
Light emitted from an array of light-emitting elements in an electrophotographic printer is transmitted through a birefringent plate that deflects light polarized in a first plane but does not deflect light polarized in a second plane perpendicular to the first plane, and through a polarization switching device that is controlled by an electrical signal so as to selectably transmit light polarized in either the first plane or the second plane. The transmitted light illuminates a photosensitive medium. Each light-emitting element can illuminate two dots on the photosensitive medium, depending on the state of the polarization switching device, thereby doubling the dot resolution.

A composite semiconductor device is formed of a semiconductor wafer having a plurality of device-forming areas in which semiconductor elements are formed and dicing areas defined between the device-forming areas, and is formed by dicing the semiconductor wafer at the dicing areas. The composite semiconductor device includes a semiconductor substrate, and a plurality of wiring layers layered on the semiconductor substrate. The wiring layers include at least conductive films. Connecting portions are formed to connect the wiring layers with each other in a layering direction of the wiring layers. Each of the connecting portions is disposed on the device-forming area side with respect to a dicing position defined in the dicing area.

An optical line terminal receives an optical signal transmitted by time division multiple access from plural optical network units among which are an optical network unit performing communications at a first bit rate and an optical network unit performing communications at a second bit rate. The optical line terminal includes a branching unit, a first receiving unit, and a second receiving unit. The branching unit branches the optical signal into branches, at an asymmetrical branching ratio. The first receiving unit receives a branch having the first bit rate, among the branches of a greater branched proportion. The second receiving unit receives a branch having the second bit rate, among the branches of a lesser branched proportion.

By doing this, it is possible to perform the rental and return operation of the motor vehicle without relying on the control center 1.
摘要:
A light emitting semiconductor device comprises an upper cladding layer (106) consisting of a first upper cladding layer (106a) provided on an active layer (105) and a second upper cladding layer (106b) provided on the first upper cladding layer (106a) to increase the light emitting efficiency and reduce the defective ratio in formation of a patterned layer. The energy band gap (Eg(106a)) of the first upper cladding layer (106a) is larger than the energy band gap (Eg(106b)) of the second upper cladding layer (106b), which is larger than the energy band gap (Eg(105)) of the active layer (105). One of a patterned layer, an dielectric interlayer (109) has an etched region at a predetermined area thereof so that at least a part of the upper cladding layer (106) or a second conductive type semiconductor region (108) is exposed.

On the first layer insulating film 12, p-side electrodes 14 to connect to the p-type semiconductor layers 13 at the first opening portions 16a and an n-side electrode 55 (an n-side contact electrode 55a and an n-side pad electrode 55b) to connect with the n-type semiconductor block 11 at the n-side opening portion 17 are formed. Furthermore, p-side common wirings 4 to connect with specific p-side electrodes 14 are formed via a second layer insulating film 18. The p-side electrodes 14 and the n-side electrode 55 are formed using the same conductive film material through a single film formation and patterning process. An Au alloy film, for instance, may be used to form the conductive film that is to constitute the p-side electrodes 14 and the n-side electrode 55.

In one aspect of the invention, a light-emitting semiconductor device has a light-emitting layer with a certain bandgap energy, an upper cladding layer with a higher bandgap energy, a first diffusion area extending into the light-emitting layer, a second diffusion area extending only into the upper cladding layer, and an electrode making contact with the second diffusion area, without covering any part of the first diffusion area. The second diffusion area conducts current to the first diffusion area, where light is emitted from a pn junction in the light-emitting layer. In another aspect of the invention, a semiconductor contact layer is provided to assure ohmic contact with the electrode, and the semiconductor contact layer is removed from the light-emitting area, avoiding absorption of light.
