Patent number: 9404912Abstract: 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.Type: GrantFiled: January 22, 2014Date of Patent: August 2, 2016Assignee: PANASONIC HEALTHCARE HOLDINGS CO., LTD.Inventors: Yoshiyuki Fujii, Kenji Okada

Patent number: 7974790Abstract: 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.Type: GrantFiled: June 19, 2008Date of Patent: July 5, 2011Assignee: Panasonic CorporationInventors: Junji Tada, Hideyuki Kurokawa, Yoshiyuki Fujii

Patent number: 7889274Abstract: 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.Type: GrantFiled: July 26, 2005Date of Patent: February 15, 2011Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kenichi Fujie, Yoshiyuki Fujii, Hisashi Ishikura, Tomoko Konda, Takayuki Yamamoto
