  • Patent number: 11500527
    Abstract: To improve convenience when creating slides for a presentation. A presentation material creation apparatus includes a material creation unit that creates a card-shaped object in which characters or a figure can be placed on the basis of an operation of a user through a GUI (graphical user interface) and places the object on a field, and also sets an order for the multiple objects, and a material playback unit that outputs a presentation material outputting the objects in the set order. When one object is superimposed on another object by an operation of the user, the material creation unit creates an object in which the one object is placed inside the other object.

  • Patent number: 8783390
    Abstract: A vehicle drive apparatus independently controls drive forces for a front-right drive wheel, a front-left drive wheel, a rear-right drive wheel, and a rear-left drive wheel using a front-right electric motor, a front-left electric motor, a rear-right electric motor, and a rear-left electric motor, respectively. The drive forces for the drive wheels of a vehicle incorporating the vehicle drive apparatus are determined based on the target moments in the yaw and roll directions of the vehicle, the total drive for the drive wheels, and the drive reaction forces at the drive wheels. Thus, the performance desired by the driver can be achieved, and the drivability therefore improves accordingly.

    Abstract: An analysis apparatus is provided with a storage tank, an injection nozzle, a syringe, a collection nozzle, a test sample tank, a microchip having two or more separation channels, detectors, a waste liquid tank, a controller, and a power supply. The collection nozzle collects a specimen which becomes a test sample from a test sample container housing the specimen, and transfers the specimen to the test sample tank. The separation channels separate characteristic components contained in the test sample. The injection nozzle is distanced from the collection nozzle and injects the test sample from the test sample tank into the separation channels. The detectors detect the separated characteristic components in the separation channels.
