Publication number: 20200208969Abstract: In a road surface condition determining device, when determining a road surface condition, a vibration detection unit, a waveform processing unit and a data transmission unit for implementing a sensing function and a data transmission function are not set continuously to an active state for all tire side device, but at least only one tire side device is set to an active state. Remaining one or more is set to a sleep state. A reduction in power consumption of the tire side devices set to the sleep state can thus be achieved. Further, with regard to the at least one tire side device, since the sensing function and the data transmission function remain in the active state, the road surface condition can be reliably determined based on the road surface data of the tire side device.Type: ApplicationFiled: March 10, 2020Publication date: July 2, 2020Inventors: Yoichiro SUZUKI, Takatoshi SEKIZAWA, Nobuya WATABE

Patent number: 10274506Abstract: In the past, when centering the center of a liquid surface and fixation thereof proved difficult during mounting a container into an automatic analytical apparatus, there was sometimes the possibility that the accuracy of checking the liquid surface conditions and the pipetting precision could not be ensured. When this problem occurred, there was the possibility that the reliability of the analysis results would be diminished. Accordingly, an automatic analytical apparatus is provided with a probe for suctioning a liquid to be used in analysis, wherein the apparatus is provided with a transport apparatus for transporting a container accommodating the liquid, and a container-clamping apparatus for clamping the container transported by the transport apparatus. The container-clamping apparatus has a vibration suppression mechanism for retaining the clamped container with an elastic body, and a centering retention mechanism with which centering of the container center can be fixed.Type: GrantFiled: January 19, 2015Date of Patent: April 30, 2019Assignee: Hitachi High-Technologies CorporationInventors: Kazuhiro Noda, Yoichiro Suzuki
