摘要:
An optical mechanism installed in an office machine, which has a machine base defining an internal space, and a paper-feeding mechanism arranged on the machine base, the paper-feeding mechanism having an inside receiving space and a bottom incident zone for the passing of light. The optical mechanism has an optical-path device formed of an image sensor and an optical module and mounted in the internal space inside the machine base, and a light-focusing structure mounted in the receiving space inside the paper-feeding mechanism above the incident zone for increasing optical path.

According to one embodiment a network switch is disclosed. The switch includes a first media access controller (MAC) coupled to a plurality of ports and a memory controller coupled to the first MAC. The memory controller is adaptable to write a first portion of packet data received from a first of the plurality of ports to a first memory device and write a second portion of the packet data from the first port to a second memory device.

A network switch includes a media access controller (MAC) coupled to a plurality of ports, a receiver coupled to the MAC, and packet queuing control (PQC) coupled to the receiver. The PQC is configured to maintain a count of the number of receive packets stored in the receiver in each of a plurality of input buffers, each input buffer associated with one of the plurality of ports coupled to the MAC. The network switch also includes at least one output buffer operably connected to the input buffers.

A roller mechanism for separating paper has a fusing roller, a following roller, and at least two paper-separating rings. The fusing roller is formed with at least two annular grooves on a periphery thereof. The two paper-separating rings are respectively mounted in the annular grooves correspondingly. The following roller is contiguous to the fusing roller for heating a paper therebetween and transporting out the paper smoothly.

A light emitting diode and a method for manufacturing the same are provided. The light emitting diode includes: a transparent substrate made of AlxGa1-xAs; a light emitting layer made of AlGaInP, stacked on the transparent substrate, and having a multiple layered epitaxially growing structure; a window layer made of GaP, stacked on the light emitting layer, and having a transparent structure with a great bandgap; an upper electrode layer overlying the window layer; and a lower electrode layer underlying the transparent substrate, wherein the x-value in AlxGa1-xAs is set to corresponding to the emission wavelengths of the light emitting layer so that the transparent substrate can have a great bandgap which make it to be transparent to the light emitted by the light emitting layer; and a window layer is used to increase the current diffusion from the upper electrode layer to the light emitting layer.
