A method of conveying documents for an ADF includes steps of beginning a first conveying procedure of a next document after a preceding document passes through a scanning section during a first conveying procedure of the preceding document, performing a first inverting procedure and then beginning a second conveying procedure of the preceding document during the first conveying procedure of the next document, performing a first inverting procedure and then beginning a second conveying procedure of the next document during the second conveying procedure of the preceding document, performing a second inverting procedure and then beginning a third conveying procedure of the preceding document during the second conveying procedure of the next document, and performing a second inverting procedure and then beginning a third conveying procedure of the next document during the third conveying procedure of the preceding document. The next document begins the first conveying procedure during the preceding document performs the first conveying procedure to improve the efficiency and speed.

An airtight multi-layer array type LED is disclosed, which comprises a metal substrate with an airtight metal frame formed thereon, and the metal substrate is integrally formed with the airtight metal frame, and an airtight sealing frame slot is formed around the upper surface of the airtight metal frame, the airtight metal frame is installed with two sets of sealing through hole pairs accommodating the lead frames. The interior of the airtight metal frame can be installed with packaging materials or optical components. The sealing holes are sealed with a glass or ceramic material. A fluorescent layer is formed on a silica gel layer, wherein the fluorescent layer can also be installed inside a silica glass package cover. The silica glass package cover is installed on the top surface of the airtight metal frame, and the silica glass package cover is engaged and sealed to a sealing rack. Nitrogen is filled in a space defined between the silica glass package cover and the fluorescent layer, so that moisture is prevented from permeating through the airtight metal frame and a dice protection layer. As such, a sealed-type LED packaging structure is formed and is suitable to be used in extreme or severe environments.

An apparatus adapted for eliminating a ghost image of point light sources is disclosed. The apparatus includes a plurality of point light sources adjacently arranged, and a plurality of medium elements provided corresponding to the point light sources. Each of the point light sources is adapted for emitting a light. Each of the medium elements includes a light input surface, and a light output surface, and both of the light input surface and the output surface are arcuate surfaces adapted for diffusing the light emitted from the point light source. The point light source emits the light, and the light is inputted from the light input surface of the medium element and outputted from the light output surface of the medium element, thus configuring a uniformly distributed light without producing a ghost image. Further, a fluorescent material may be mixed in the medium element for obtaining a color combined light.

An electrical connector includes a pedestal terminal which has a base board, two fastening boards extending upward from two sides of the base board, and two elastic boards extending upward from two free ends of the fastening boards and inclined gradually away from each other in process of extending upward, and a connecting terminal having two elastic arms and a bent portion connecting the elastic arms together to make the connecting terminal show a substantial inverted-V shape. Two free ends of the elastic boards are bent inward to form two restraining portions. Two free ends of the elastic arms are arched outward to form two interfering portions. The connecting terminal is movably engaged with the pedestal terminal with the elastic arms restrained between the restraining portions, the interfering portions abutting against insides of the corresponding elastic boards and the bent portion projecting upward beyond the pedestal terminal.

A key structure having an improved light emitting efficiency is provided. The key structure includes a light guide plate, an isolation sheet, a circuit board, an elastic member, and a key cap sequentially disposed one on another in order. A circuit and a plurality of first electrical contacts are distributed on a top surface of the light guide plate. An optical structure is disposed at a bottom surface of the light guide plate. The isolation sheet has a light reflective surface facing the light guide plate. A light source emits a light into the light guide plate. The light is reflected by the optical structure to pass through the through holes configured at the isolation sheet, thus allowing more light outputting through the through holes, so as to improve the illumination of the key cap, and improve the light emitting efficiency.

A probe connector includes an insulating housing of which a top protrudes upward to form a plurality of inserting pillars each defining an inserting hole vertically penetrating therethrough, and a bottom defines a plurality of fixing holes each vertically extending to be connected with a bottom of one inserting hole. A plurality of probe pins is inserted upward in the inserting holes through the corresponding fixing holes respectively. A shielding body made of metal defines a plurality of inserting openings arranged in accordance with the inserting pillars and each vertically penetrating through the shielding body. The inserting pillars each are inserted in one of the inserting openings with a top end of the probe pin stretching in the corresponding inserting opening, so that each of the probe pins is enclosed by the shielding body to make the probe pins separated from one another by the shielding body.

A memory system includes a NAND flash memory, a NOR flash memory and a SRAM memory on a single chip. Both NAND and NOR memories are manufactured by the same NAND manufacturing process and NAND cells. The three memories share the same address bus, data bus, and pins of the single chip. The address bus is bi-directional for receiving codes, data and addresses and transmitting output. The data bus is also bi-directional for receiving and transmitting data. One external chip enable pin and one external output enable pin are shared by the three memories to reduce the number of pins required for the single chip. Both NAND and NOR memories have dual read page buffers and dual write page buffers for Read-While-Load and Write-While-Program operations to accelerate the read and write operations respectively. A memory-mapped method is used to select different memories, status registers and dual read or write page buffers.
