  • Patent number: 7810280
    Abstract: The force from a drive rod driven by an electric motor is transmitted via a link arm pivotally linked to the drive rod and a back door. When the back door is operated in an open direction, the link arm is supported by an open-side support slider and the acting direction of the force applied to the link arm by the drive rod is shifted to the opening direction of the back door. When the back door is operated in a closing direction, the link arm is supported by a closed-side support slider and a closed-side support roller and the acting direction of the force applied to the link arm by the drive rod is shifted to the closing-direction of the back door. The open-side and closed-side support sliders are pressed against the link arm by leaf spring members so that the link arm is prevented from oscillating between the sliders.

  • Publication number: 20100245051
    Abstract: A communication method for a noncontact RF ID system that uses a first waveform, a second waveform, and a third waveform, wherein the first waveform and the second waveform are formed by a basic waveform having one of a rising or falling state transition at the approximate center of the waveform, the third waveform is formed by a plurality of basic waveforms that have one state transition at the approximate center part of the waveform, and the third waveform generates one state transition only at the approximate center of the plurality of basic waveforms. In addition, communication is carried out by using the third waveform in place of the first waveform and the second waveform in the case in which communication is carried out using a first waveform and a second waveform and one state transition is generated outside the approximate center part of the basic waveform.

  • Patent number: 6893106
    Abstract: A printing apparatus and an ink-discharge status detection method which perform appropriate print control by detecting discharge failure with a simple construction, without reducing the printing speed. The apparatus, to which the method is applied, performs test ink discharge from a part of nozzles of a printhead while scanning the printhead, and detects ink discharge statuses of the nozzles of the printhead by using a photosensor in an area between the home position of the printhead and a position outside of an effective printing area. In next detection, nozzles different from those used in the previous test ink discharge are used for performing test ink discharge, and discharge statuses are detected. Discharge statuses of all the nozzles are detected in forward and backward scannings or a plurality of scannings.

  • Patent number: 6797972
    Abstract: A high-polymer neutron shielding material which scarcely reduces the hydrogen number density when exposed to a high temperature of 150 to 200° C. for a long time period A heat-setting type epoxy resin is employed. The base resin is selected from various epoxy resins such as bisphenol A type epoxy resin. The hardener is selected from alicyclic polyamine, polyamide amine, aromatic polyamine, acid anhydride, and so on. These materials are mixed and hardened at a temperature higher than the room temperature. To give a flame resistance to the hardened resin, a fire retardant such as magnesium hydroxide is added to the mixture. To improve the neutron shielding performance of the hardened resin, a neutron absorbing material is added to the mixture. Further, to increase the moderating performance, hydrogenated bisphenol A epoxy resin is used as the base resin or metal hydride or hydrogen absorbing alloy is added.
