Abstract: An exhaust gas purification catalyst includes a substrate and a catalyst layer on the substrate. The catalyst layer includes lower and upper catalyst layers. The lower catalyst layer includes a powder material containing a powdered carrier, and catalyst metal particles containing Rh on the carrier. The upper catalyst layer includes an upstream catalyst layer in an upstream side in an exhaust gas flow direction, and a downstream catalyst layer in a downstream side in the exhaust gas flow direction. At least the upstream catalyst layer of the upstream and downstream catalyst layers includes a powder material containing a powdered carrier, and catalyst metal particles containing Pd on the carrier. A cumulative 50% particle size D50 in a volume-based particle size distribution of the powder material included in at least the upstream catalyst layer of the upstream and downstream catalyst layers is 6 ?m or more and 10 ?m or less.

Abstract: A separating apparatus includes a notch device configured to form a notch by inserting a sharp member into a side surface located most adjacent to a separation start point; a first holder including a start point side attraction member and a start point side elevating mechanism; a second holder configured to attract and hold a second substrate; a detection device; and a controller configured to form the notch in the side surface, and lower the start point side attraction member to attract it to a first substrate. The controller moves the start point side attraction member from a standby position to a speed-change position at a first speed; moves the start point side attraction member from the speed-change position to be close to the first substrate at a second speed; and stops the start point side attraction member when it is determined that the first substrate is attracted.

Abstract: A separating apparatus includes a first holder configured to move a first substrate to be away from a second substrate; a second holder; a controller configured to move the first substrate to be away from the second substrate; a light emitting device configured to emit light parallel to a bonding surface between the first substrate and the second substrate; and a light receiving device configured to receive light emitted from the light emitting device. In a case where the light from the light emitting device is not received by the light receiving device due to separation of a part of the first substrate from the second substrate and then the light is received, the controller determines whether separation of the first substrate from the second substrate is completed based on a position or a movement direction of the first holder with respect to the second holder.

Abstract: An analysis method for a rubber composition includes the followings: (1) acquiring input data generated from a microscopic image obtained by image-capturing a rubber composition with a microscope, the microscopic image showing a formulation contained in the rubber composition; (2) inputting the input data to a trained machine learning model; and (3) deriving output data from the trained machine learning model. The output data is data defining a region that appears in the microscopic image corresponding to the formulation.

Abstract: [Problem] To provide a control method of avoiding drop of a throughput by solvent substitution and of avoiding increase of a solvent consumption amount in a control method for an automatic analyzer including a liquid chromatograph that includes plural analysis flow passages arranged to be parallel to each other. [Solution] Which one of plural analysis flow passages 105 to 107 is to be used is determined in introducing plural separation processes using solvents whose kind is different from each other with a time lag relative to one another, and a solvent used in a next separation process executed at timing after starting the plural separation processes determined to be introduced with a time lag relative to one another and each of the solvents used in the plural separation processes determined to be introduced with a time lag relative to one another are compared.

Abstract: A method of controlling an automatic analyzer includes searching for a substitute stream that can be substituted, in a case where an abnormality of a stream is detected for a liquid chromatograph having multiple streams, after setting an analysis schedule; and modifying the analysis schedule, if a substitute stream exists, so that a sample scheduled to be introduced into the stream which has the abnormality is introduced into the substitute stream, and treatment timings of the sample which has passed through the substitute stream and the sample which has passed through another normal stream in the detector do not overlap with each other, in which the automatic analyzer includes a pretreatment unit that purifies a sample; a separation unit; and a detector that detects a separated sample, and a treatment timing of the sample in the separation unit and the detector is controlled based on the analysis schedule.

Abstract: In an automatic analyzer where a plurality of types of separation column are selectively used for performing a chromatographic analysis, an automatic analyzer configured to install a separation column of an intended type at an aimed position, and a method for installing the separation column in the automatic analyzer are provided. Identification mechanisms, a computer, and a display unit are included. The identification mechanisms read identifiers included in separation columns when the separation columns are installed at installation positions. The computer determines whether identification information of the identifiers read by the identification mechanisms matches an installation pattern registered in advance or not. The display unit notifies an alarm when the identification information is determined not to match the installation pattern by the computer.
