  • Patent number: 6652033
    Abstract: A leg rest and a seat back are rotatably mounted at the front and rear of a seat cushion of a passenger seat respectively, and a footrest is mounted on the leg rest in such a manner that it can be extended and retracted. Adjustment of the angle of the seat back and the leg rest, and positioning of the footrest are performed with a seat back actuator, a leg rest actuator, and a footrest actuator. A contact sensor is provided at the end of the footrest, wherein when the contact sensor detects contact with an obstacle, downward rotation of the leg rest is stopped and the footrest is moved backward. When the leg rest or the footrest is moved, the interference of the obstacle with the footrest such as a baggage can reliably be prevented.

  • Patent number: 6578947
    Abstract: The present invention provides an ink drying prevention apparatus that can prevent ink within an ink-jet recording head from drying, for a long period of time. The ink drying prevention apparatus prevents ink within an ink-jet recording head from drying, and includes a porous substance permeated with a seal liquid that is nonvolatile and incompatible with the ink within the head, wherein the porous substance can contact a nozzle surface of the ink-jet recording head. The seal liquid forms plural meniscuses in an interface with the nozzle surface and inside the porous substance to block air paths, thereby preventing ink within a nozzle exposed to the nozzle surface from drying.

  • Publication number: 20030051801
    Abstract: A screen printing plate which includes an ink permeable member through which ink permeates, and an ink blocking material which adheres to the ink permeable member and blocks permeation of ink. The fluid ink blocking material is ejected onto the ink permeable member. Alternatively, the fluid ink blocking material is ejected onto an intermediate transfer member and then transferred onto the ink permeable member. The ink blocking material solidifies on the ink permeable member, thereby forming a pattern of ink blocking material on the ink permeable member. The ink blocking material is preferably ejected using an ink jetting device.

  • Patent number: 6283579
    Abstract: A recording head for carrying out printing by jetting ink drops for deposition at predetermined positions on recording media, and allowing minute drops to be jetted without using a nozzle to record high-definition images. The recording head includes an elastic member vibrating in response to the excitation of a vibration generating means vibrating in accordance with a pixel signal, wherein capillary waves are generated on the surface of ink by the vibration of the elastic member to jet the ink for deposition on recording media. The elastic member is of a cantilever construction that bending vibration is made by excitation.

  • Patent number: 6046201
    Abstract: N-(12-Nitroxydodecyl)-6-(4-ethyl or isopropyl-1-piperazinyl)pyridine-3-carboxamide or physiologically acceptable salts thereof. The said compounds have excellent inhibiting activity of cerebral edema, especially ischemic cerebral edema, and inhibiting activity of delayed neuronal death (an inhibiting activity of Ca-influx in neuronal cells). Cerebral edema is a pathologic condition accompanying cerebrovascular disorders, especially the acute stage cerebrovascular disorders and then the compounds are useful as an inhibiting agent for cerebral edema or a therapeutic agent for cerebrovascular disorders. Moreover, because the compounds do hardly show a behavior suppressing action, which is considered to be side effect in treating cerebrovascular disorders at the acute stage, they are an excellent therapeutic agent for, in particular, the acute stage cerebrovascular disorders.
