  • Patent number: 10377497
    Abstract: There is provided an anti-icing system that has a simple structure and makes it possible to exert anti-icing performance by dealing with displacement of a stagnation point without increasing air resistance. The anti-icing system according to the present invention blows heated gas to an inner surface of a wing of an aircraft, and includes: a piccolo tube that includes a flow path through which the heated gas flows in a longitudinal direction from a rear end to a front end, and a plurality of ejection holes provided along the longitudinal direction to make the flow path communicate with an outside; and a supply source that supplies the heated gas toward the piccolo tube. The piccolo tube is held to cause positions of the respective ejection holes to be fixed in a gravity direction.

  • Patent number: 10315775
    Abstract: An aircraft duct structure includes a first duct through which exhaust air from a front-side equipment compartment flows, and a second duct through which exhaust air from a rear-side equipment compartment flows. The first duct has a terminal end part where the exhaust air inside the second duct flows into the exhaust air inside the first duct at a substantially right angle, and a flow straightening plate located inside the terminal end part. The terminal end part has a jet opening which faces, across a clearance, an air pressure regulating port where an air pressure regulating valve is disposed. The inside of the terminal end part is divided by the flow straightening plate into an upper region and a lower region. The exhaust air inside the first duct and the exhaust air inside the second duct merge together in the upper region.

  • Patent number: 8226002
    Abstract: A conductive fixed static elimination member is provided in a before-magnetic head travel portion which guides a magnetic card to a magnetic card reader unit provided with a magnetic head, such that a protuberance portion thereof protrudes into a card travel groove through an opening formed in one of side walls, and has a conductive cleaning pad affixed to a surface thereof. The magnetic card inserted in the before-magnetic head travel portion is cleaned by the cleaning pad, and if the magnetic card has static electricity, it is possible to eliminate the static electricity by discharging the static electricity to the ground via the cleaning pad having conductivity, the fixed static elimination member, and a magnetic card reader fixing bracket.

  • Patent number: 8162217
    Abstract: A magnetic head is held by a side wall through a head fixing fitting so as to freely advance into and retreat from a card sliding groove. First and second head urging levers are swingably supported through a pin. In a standby state, the magnetic head is away from the card travel groove, and card engaging sections of the first and second head urging levers are staying in the card travel groove. When a magnetic card slides in a card sliding direction, the magnetic card makes contact with a card contact section to push the card contact section away from the card travel groove. This causes the first head urging lever to push out the magnetic head into the card travel groove so that the magnetic head makes contact with the magnetic card.

  • Patent number: 6728015
    Abstract: A bar code reader having two reading windows, i.e., a bottom window and a side window. An increased number of scanning lines are used for constituting scanning patterns for scanning bar codes, and the arrangement of the optical system is contrived to decrease the whole size of the bar code reader and, particularly, to decrease the depth of the bar code reader. A source of laser light, a splitter for splitting the laser beam emitted from the laser light source into two, a reflection mirror for transmitting one beam from the splitter to a polygon mirror, the polygon mirror which rotates to scan the incident laser beam, a mirror system for emitting the beam reflected by the polygon mirror through the reading window, and a focusing member for focusing the beam reflected by the bar code onto a detector that detects the beam reflected by the bar code, are arranged on the same line in the bar code reader. By using a concave mirror, furthermore, the beam reflected by the bar code is folded back to one detector.

  • Patent number: 6631844
    Abstract: A multi-head optical scanning device used for a bar code reader having a reduced thickness and realizing more complete 360° bar code reading. The scanning device includes a bottom part, a side part which is nearly vertical to the bottom part, a light source, a polygon mirror and a light detector contained inside the body of the side part. Light beams are emitted from the light source so that they are nearly vertical to the surface of the bottom part, and the polygon mirror has a rotation axis at a position which is nearly parallel to the surface of the bottom part. The optical scanning device eliminates the need for a mechanism which performs scanning inside the bottom part and the degree of freedom with which each of the pattern mirrors is disposed is increased, and provides a scanning pattern whose reading capacity can be upgraded by using a scanning pattern which is emitted from the bottom part.
