  • Patent number: 9712039
    Abstract: An in-vehicle power conversion system, which can shield a circuit unit without using a particular shield member and can achieve reduction in cost and size, is obtained. Included are: a conductive housing having an opening; and a multilayer printed wiring board in which circuit units are mounted and one layer is a GND plane. The multilayer printed wiring board is assembled to an opening surface of an opening of the conductive housing to form a closed space; and the GND plane of the multilayer printed wiring board is electrically connected to the conductive housing to shield the circuit units stored in the closed space surrounded by the conductive housing and the multilayer printed wiring board.

  • Patent number: 9404912
    Abstract: A protective cap 2 is engaged with a latch 10 of a diluent container 5 so as to fix the diluent container 5 at a liquid holding position of a diluent container containing section 11. The engagement is released when the protective cap 2 is set to an open position against the engagement so as to expose an inlet 13. When the protective cap 2 is shifted from the open position to a closed position, the protective cap 2 pushes the diluent container 5 into a liquid discharge position. Thus, it is possible to preserve a diluent for a long period of time and to easily open the diluent container 5 without having to complicate the structure of an analysis apparatus.

  • Patent number: 7974790
    Abstract: A particulate determination method determines by onetime scanning, the size of a particulate included in a plurality of particulates of various sizes which are arranged on a disc. False recognition of the number of particulates is avoided even when a plurality of particulates are adjacent to each other. A photodetector detection signal is judged using plural threshold values according to the sizes of particulates to be detected. Results of determinations corresponding to the respective threshold values are stored on mutually independent memory maps. When counting particulates, a particulate size and a particulate count value are determined from a combination of stored data appearing in a scanning window at the same position on the respective memory maps.

  • Patent number: 7889274
    Abstract: An image input apparatus can acquire an image with a high contrast without saturating a camera output even for a subject having a large light and dark difference while achieving a wide dynamic range. An image sensor has an input-output characteristic varying with a plurality of regions delimited according to a difference in the amount of incident light. A video luminance signal level is detected from a video signal of the image sensor. An amount of light on a screen is calculated from the image luminance signal level. The image sensor is adjusted to make the amount of light on the screen coincide with a target light amount. The target light amount is set such that a relation between the target light amount R and an amount of light Q at a change point that is at the lowest luminance in an input-output characteristic of the image sensor satisfies R<Q.
