Title: Paper feeding device and method, and image reading device
Inventor: WATANABE HIROTAKE
IPC: B65H3/06
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To enhance paper separating performance by arranging separating gate moving according to movement of a drawing roller and regulating the number of paper sheets carried by the drawing roller to the separating roller between the drawing roller and the separating roller. SOLUTION: The separating gate 30 is arranged adjacently to a paper table 28 and perpendicularly to the paper table 28 between the drawing roller 10 and a final separating part 50. The separating gate 30 has a vertical part 32 and a curved part 34. Because the vertical part 32 is perpendicular to a carrier direction FD of paper, paper to be carried is prevented from being carried in the carrier direction FD when paper hits on the vertical part 32. Because the curved part 34 is curved toward the carrier direction FD of paper, paper is carried in the carrier direction FD along a curved surface, even if paper hits on the curved part 34.  By this constitution, the separating gate 30 permits only carrying of the prescribed number of sheets on an upper part and regulates carrying of paper under the upper part because moving of paper in the carrier direction FD is hindered by the vertical part 32.

Title: Semiconductor device of multi-layer construction
Inventor: JIYON RENII
IPC: H01S5/323
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce a voltage drop occuring at a barrier portion by radiating impurities which create spots on hetero interface during the formation of a hetero junction and by passing electrons and holes through a barrier created at the hetero interface by means of a tunnel current. SOLUTION: A GaAs-ZnSe boundary is irradiated with 10<13> cm<-2> of B as impurities which create spots. A tunnel current flowing through a hetero junction is increased, and an excessive voltage is reduced. An operating voltage is 5V for a sample which is not irradiated with B but the operating voltage is very low or 2.5V for a sample irradiated with B. By doing this, a lower voltage and a longer operating life can be achieved for a ZnSe-based or a GaN-based laser device or a light emitting diode. Also, by optimizing the density of impurities to be introduced to the interface, a saturated tunnel current region can be created and a laser light emitting diode having a self-current limiter can be obtained, thereby economizing the equipment including a power supply.
