  • Patent number: 6340982
    Abstract: An exposure device in which an image forming lens is disposed in such a posture that the center line of an image forming is out of axial alignment with the center of beam intensity distribution of the light emitting diode output (the center of beam intensity distribution) so as to reduce possible incidence of stray light when local part of the light output from the light emitting diode array reflects on said wires. As a result, the stray light does not strikes the circumference surface of the image supporting body and the vivid image can be formed.

  • Patent number: 6340617
    Abstract: A method of manufacturing a semiconductor device having shallow p-n junctions and silicide regions, capable of meeting both requirements of a high annealing temperature and a low annealing temperature. A lamination of two films made of materials having different etching characteristics is formed on the surface of a silicon substrate, covering an insulated gate electrode structure. The upper film is anisotropically etched to form side wall spacers. Impurity ions are implanted into a surface layer of the silicon substrate and sufficiently activated to a first level. The lower film is removed by using as a mask the side wall spacers, and a metal film capable of being silicided is deposited to perform a first silicidation reaction. The insulated gate electrode is exposed and impurity ions are implanted shallowly in the surface layer of the silicon substrate.

  • Patent number: 6340378
    Abstract: A process and apparatus for separating briquettes and fragments in a product stream resulting from briquetting direct reduced iron. Separating and cooling of the briquettes and fragments are carried out simultaneously in an initial step with use of separating means submerged in a cooling bath. The process enables use of less rugged apparatus following the initial step and the apparatus is not subjected to handling the product stream at the elevated temperatures at which briquetting is carried out. Capital expenditure and equipment maintenance is thus reduced.

  • Patent number: 6339692
    Abstract: This invention relates to a printing device that performs fixation after transfer, and which prevents the occurrence of no transfer even when feeding the paper backward starting printing from the next page after the final page. This printing device comprises image-formation units (3, 4) that transfer a toner image, a fixation unit (5), and a control unit (10). The control unit (10) control adjustment of the moisture content on either the final page or leading page. In order to do that, it lowers the fixation energy of the fixation unit (5) for the final page. There is a moisture-adjustment mechanism (16) that reduces the moisture content of the leading page. Heat energy is applied to the leading page by the fixation unit (5). This reduces the difference in the amount of shrinkage between the final page and the leading page, and prevents wrinkling of the leading page.

  • Patent number: 6338654
    Abstract: A connector housing has a lock arm for locking a terminal therein. The lock arm deflects in an complete insertion state of the terminal so that a spacer abuts against a side surface of the lock arm. The lock arm is formed with a projection which abuts the incompletely inserted terminal in the spacer advancing direction. The projection may be a plate piece elongated in the longitudinal direction of the lock to be pinched by a pair of a resilient contact plates of the terminal. Alternatively, the lock arm may have a protrusion engaging with an engagement hole formed in the connector housing. The protrusion is a rectangular plate extending from the fore end of the lock arm. An inclined guide surface continuos with the engagement hole may be provided in the connector housing. Alternatively, the connector housing may have an inner embossed wall positioned closely to the deflected lock arm to oppose to the spacer.
