  • Patent number: 10473597
    Abstract: A neutron grid, comprises: a grid including: a plurality of spacers through which at least a part of first neutrons from a target passes; and a plurality of absorbers to absorb at least a part of second neutrons scattered thorough the target, the spacers and the absorbers being alternately arranged along a first direction and extending along a second direction intersecting with the first direction; and a pair of covers through which at least a part of the first neutrons and at least a part of the second neutrons pass, sandwiching the grid along a third direction intersecting with the first and second directions. A thermal expansion coefficient difference between one of the spacers and one of the absorbers is ±9×10?6/° C. or less, or Young's modulus of the spacer is 100 GPa or more.

  • Patent number: 10374509
    Abstract: In a control circuit for controlling a power converter that includes a switch, a power supply circuit outputs electrical power, and a command generator generates a switching command that controls switching operations of the switch, based on the electrical power output from the power supply circuit. A failure mode determiner executes a determination of whether which of failure modes has occurred in the power supply circuit, and outputs a result of the determination. A switch controller selectively executes, based on the result of the determination, a first switch control task and a second switch control task. The first switch control task forcibly shuts down the switch independently of the switching command, and the second switch control task enables the switching operations of the switch to be continuously controlled based on the switching command.

  • Patent number: 8360499
    Abstract: A decorative molding that is to be fixed to a frame of a framed window glass plate for a vehicle is provided. The decorative molding is configured such that when the frame is formed around a peripheral portion of a glass plate by injecting a molten resin, the decorative molding is simultaneously fixed to the frame. The body of the decorative molding is made of a metal. A cationically electrodeposited coating film is formed on a surface of the body of the decorative molding and a resinous coating film is formed on the cationically electrodeposited coating film.

  • Publication number: 20120025554
    Abstract: Summary: Task: In a field wherein a frame is formed around a peripheral portion of a glass plate by injection molding and a decorative molding is simultaneously fixed to the frame upon the injection molding, there are provided a decorative molding and a framed window glass plate having the decorative molding mounted thereto, the decorative molding being suppressed from an appearance failure at the time of injection molding and suitable for a multi-coloring. Means for achieving Task: A body proper of the decorative molding is made of a metal, a cationically electrodeposited coating film is formed on a surface of the body proper, and a resinous coating film is formed on the cationically electrodeposited coating film. By containing a pigment or dye in the resinous coating film which is made of a melamine-based resin, acrylic resin, polyester-based resin, fluororesin or epoxy resin, the decorative molding has the same color as the frame and the body of the vehicle, which is a feature.

  • Patent number: 7037621
    Abstract: A metal plate and an electrode in a polymer lithium ion secondary battery or the like are welded certainly, and it is accomplished to further improve the reliability and the durability thereof. Each of an upper metal plate (7a) and a lower metal plate (9a) on the positive pole/terminal is welded to a pole/terminal of positive electrode (3) so that the pole/terminal of positive electrode (3) may be sandwiched from each of the upper and lower sides. Moreover, each of an upper metal plate (7b) and a lower metal plate (9b) on the negative pole/terminal is welded to a pole/terminal of negative electrode (5) so that the pole/terminal of negative electrode (5) may be sandwiched from each of the upper and lower sides. This eliminates occurrence of poor welding in the electric resistance welding.
