  • Publication number: 20240144504
    Abstract: A crankshaft shape inspection method includes: acquisition step that acquires three-dimensional point cloud data of a surface of a crankshaft S; generation step that generates, while using the three-dimensional point cloud data, first point cloud data based on point cloud data generated by performing isolated point removal processing that removes data points whose distance to the nearest neighbor data point is equal to or more than first threshold value Th1 and generates second point cloud data based on point cloud data generated by performing isolated point removal processing that removes data points whose distance to the nearest neighbor data point is equal to or more than second threshold value Th2 (>the first threshold value Th1); and a calculation step that calculates a side dimension of a counterweight SC using the first point cloud data and calculates a longitudinal position of the counterweight SC using the second point cloud data.

  • Patent number: 11966716
    Abstract: An information processing apparatus includes an annealing control unit, a spin interaction memory, a random number generation unit, and a spin state update unit and obtains a solution by using an Ising model. The annealing control unit controls an annealing step and a parameter of a temperature and a parameter of a self-action. The spin interaction memory stores the interaction coefficient of a spin. The random number generation unit generates a predetermined random number. The spin state update unit includes a spin buffer that stores values of a plurality of spins, an instantaneous magnetic field calculation unit that calculates instantaneous magnetic fields of the plurality of spins, a probability calculation unit that calculates update probabilities of the plurality of spins, and a spin state determination unit that updates the values of the spins based on the update probabilities and a random number.

  • Patent number: 11912775
    Abstract: A monoclonal antibody is provided which binds to a human CC chemokine receptor 1 (CCR1) and inhibits activation of the human CCR1, or an antibody fragment thereof. The monoclonal antibody binds to an extracellular region of a human CCR1 and inhibits activation of the human CCR1 by a human CC chemokine ligand 15 (CCL15). An antibody fragment thereof, a hybridoma producing the antibody, a nucleic acid having a nucleotide sequence encoding the antibody or the antibody fragment, a transformant cell containing a vector containing the nucleic acid, a method for producing the antibody or the antibody fragment using the hybridoma or the transformant cell; a therapeutic agent and a diagnostic agent containing the antibody or the antibody fragment, and a method for treating and diagnosing a CCR1-related disease using the antibody or the antibody fragment are also provided.

  • Patent number: 11040280
    Abstract: A game processing method that causes a computer to execute a game program includes displaying, with a touchscreen, a reference operation and a deck that comprises an item, receiving a first input operation to select the deck and second input operations, determining a matching degree between the reference operation and each of the second input operations, outputting, from a processor to a memory, a level of the matching degree based on the determination, counting, with the processor, a number of consecutive times that the level continuously exceeds a predetermined threshold level, calculating, with the processor, a score of the user based on the number, and outputting, from the processor to the memory, the score. When the item comprises a card having a predetermined effect and continuation of exceeding the predetermined threshold level is interrupted, the number is counted as if no interruption has occurred.
