  • Publication number: 20100076190
    Abstract: The problem to be solved by the present invention is to provide a highly-versatile method for producing a nitroxyl radical derivative, in which position-2 and position-6 in a TEMPO-based compound can be easily substituted, and further, a method for producing a nitroxyl radical derivative, in which a nitrogen nucleus is labeled with 15N. The above-described problem can be solved by reacting a triacetoneamine derivative with ketone or aldehyde in the presence of ammonium salt or a 15N-labeled compound thereof to obtain a 2,6-substituted-4-piperidone derivative.

  • Patent number: 7682667
    Abstract: An adhesion strength of spray coating comparable to that obtained in a conventional combination of blast treatment and gas flame spraying can be realized even if roughening is conducted with the use of simple tools by performing in advance such a roughening treatment that the average roughness (Ra) of the surface of the thermal spray subject falls within the range of 2 to 10 ?m with the use of a grinding tool, and thereafter carrying out thermal spraying under such conditions that the average area of each of molten particles when molten particles of a thermal spray material have stuck to the surface of thermal spray subject falls within the range of 10000 to 100000 ?m2. In the roughening by grinding tools, a large-scale apparatus is not needed as different from the blast treatment, and portable small tools can be used in overhead location work at field repair. The scattering of powder resulting from grinding is slight so that the danger of environmental pollution is low.

  • Publication number: 20100043731
    Abstract: A medium circulating apparatus of engine oil, which improves startability and warm up ability of an internal combustion engine, includes a microbubble generator that generates microbubbles and mixes the microbubbles into the circulating engine oil. Further, the medium circulating apparatus includes a medium temperature acquiring unit that acquires a temperature of the engine oil. The microbubbles are generated by the microbubble generator when the temperature of the engine oil is less than or equal to a predetermined value in order to decrease a viscosity, a heat conductivity, and a heat capacity of the engine oil in which the microbubbles are mixed.

  • Publication number: 20090288647
    Abstract: A fuel supply apparatus that supplies fuel to an internal combustion engine by injecting liquid fuel from a fuel injection valve into a suction port is configured by a microbubble generator that generates microbubbles and an ultrasonic wave generator that generates an ultrasonic wave depending on a gas in the microbubbles generated by the microbubble generator. In the fuel supply apparatus, the generated microbubbles are mixed into the liquid fuel that is supplied to the fuel injection valve, and the liquid fuel in which the microbubbles are mixed is irradiated with the ultrasonic wave depending on the driving state of the internal combustion engine. When the liquid fuel in which the microbubbles are mixed is irradiated with the ultrasonic wave, a temperature of the liquid fuel is raised instantaneously due to contraction of the microbubbles.

  • Patent number: 7557761
    Abstract: An array antenna apparatus includes a first feeding element having a first feed point, a second feeding element having a second feed point, and a first parasitic element electrically connected to the respective first and second feeding elements. In a first frequency band, respective resonances in the feeding elements occur independent of each other, by eliminating electromagnetic mutual coupling between the feeding elements, and exciting the first feeding element through the first feed point as well as exciting the second feeding element through the second feed point. In a second frequency band lower than the first frequency band, a loop antenna having a certain electrical length is formed by the first and second feeding elements and the first parasitic element, and a resonance of the loop antenna substantially occurs by exciting the first feeding element through the first feed point.

  • Publication number: 20090066644
    Abstract: An input control device and an image forming apparatus capable of proving an easy-to-use operating environment even for a user having difficulties operating such conventional devices and apparatuses due to his/her height, color vision deficiency, weak vision, use of a wheelchair, and the like is disclosed. In the input control device, based on the detected distance between an instruction item on the display and an operation direction means (such as a user's finger), the display mode of the instruction item is changed (by, for example, changing positions, colors, and combinations). Further, as the operation direction means approaches, the size of the instruction item on the display becomes larger, thereby improving the operability especially for a user with color vision deficiency or weak vision.

  • Publication number: 20090060612
    Abstract: The height of an image reading unit or an operating panel in an image forming apparatus is adjusted to facilitate their operation depending on the physical characteristics of a user, such as his height or use of a wheel chair. A second operating panel and a second automatic document feeder (ADF) are disposed on the side of the image forming apparatus, so that a user on a wheel chair can access them easily. The second ADF houses plural sheet trays that are configured to open or close together. When the sheet trays are closed, a first operating panel disposed at the top of the apparatus is activated while the second operating panel on the side is deactivated. When the sheet trays are open, the second operating panel is activated while the first operating panel is deactivated.

  • Publication number: 20090031978
    Abstract: A heat accumulator (1) is formed by connecting a first container (4) and a second container (5) using a spring (6). The first container (4) has a wall-shaped inner side wall that corresponds to the shape of a cylinder bore wall (7). Provided on this inner side wall is a flexible structural part (8). The flexible structural part (8) is formed of highly elastic resin. The second container (5) has a similar structure. A heat storage medium within the first container (4) and the second container (5) absorbs heat, which generates a change of phase from a solid to a liquid. When this happens, the volume of the heat storage medium increases. The increase in the heat storage medium projects the flexible structural part (8), and separates the first container (4) and the second container (5) from the cylinder bore wall (7).

  • Publication number: 20090020366
    Abstract: An oil pan (130) comprises an oil pan cover (131) storing oil in an internal space and an oil pan separator (132) positioned in the internal space. The oil pan separator (132) is positioned so as to divide the internal space into a first chamber (30a), which has an oil strainer (41) at its bottom, and a second chamber (30b), which is adjacent to the first chamber (30a). The oil pan separator (132) includes a slope plate (132c) for capturing return oil that flows back from a cylinder block (20a) to an oil pan (130). Part of the captured return oil flows to the second chamber (30b) via a communication hole (132f) that is provided in the slope plate (132c). The remaining captured return oil flows into the first chamber (30a). This ensures that the oil level in the second chamber (30b) is higher than that in the first chamber (30a). Therefore, when a solenoid valve (133) opens at the end of a warm-up operation, the oil in the second chamber (30b) flows into the first chamber (30a).

    Abstract: An oil pan separator 132 is disposed so as to divide a space within an oil pan 130 into a first chamber 30a and a second chamber 30b. The oil pan separator 132 has a protrusion 132b formed at a low position in such a manner that a portion of the first chamber 30a protrudes into the second chamber 30b. A protrusion upper-plate 132b1, which serves as an upper end portion of the protrusion 132b, is provided with an oil feed valve 138, which is a one-way valve, for allowing substantially only outflow of oil from the first chamber 30a to the second chamber 30b.
