Publication number: 20240125812Abstract: An automatic analyzer includes a dispensing mechanism having at least one horizontal drive shaft and one vertical drive shaft for moving the dispensing nozzle, a first mechanism having a stop position at which the dispensing nozzle is stopped, and a control section for positioning the dispensing nozzle with the stop position of the first mechanism. A member is disposed on the first mechanism to indicate predetermined first and second positions of the first mechanism so that the first and the second positions are detected by sensing the member using the dispensing nozzle. Based on the displacement between the first and the second positions indicating the displacement of the relative position between the dispensing mechanism and the first mechanism, the control section calculates a correction value for correcting the displacement of the stop position caused by fluctuation in a relative position between the dispensing mechanism and the first mechanism.Type: ApplicationFiled: February 24, 2022Publication date: April 18, 2024Applicant: Hitachi High-Tech CorporationInventors: Kenshiro SAKATA, Yoshihiro KABE, Takuya TAKAHASHI

Publication number: 20240123998Abstract: The driver assistance system comprises a detector, a navigator, a stimulator, and a voice interactor. The detector detects wakefulness reduction of a driver or absent-minded driving by the driver. The navigator navigates a vehicle based on map information. The stimulator continuously or intermittently applies stimulation to the driver. The voice interactor interacts with the driver by voice. The navigator searches for a resting facility on a route from the map information in response to a detection of the wakefulness reduction or the absent-minded driving. The voice interactor executes a first interaction of proposing navigation to the resting facility by the navigator in response to the detection of the wakefulness reduction or the absent-minded driving, and executes a second interaction of proposing application of stimulation by the stimulator after an execution of the first interaction and during a period until the vehicle arrives at the resting facility.Type: ApplicationFiled: December 19, 2023Publication date: April 18, 2024Inventors: Masataka SANO, Koichiro YAMAUCHI, Takuya SAKATA
