  • Patent number: 12103229
    Abstract: The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. Then, solutions of first and/or second binding agents are printed on the powder bed in a predetermined pattern. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The removable binding agent is then removed. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

  • Patent number: 12104349
    Abstract: Provided is a construction machine configured such that a hydraulic actuator is driven by a hydraulic pump for a closed circuit, by which oil film breakage of the hydraulic pump for a closed circuit is prevented to improve the reliability and a high operation rate can be obtained. The construction machine includes a switching valve that is provided in a branch hydraulic line connecting one of suction/delivery ports of a closed circuit pump and a charge line to each other and is opened and closed according to a control signal from a controller. The controller is configured to, in a case where a state in which a delivery volume of the closed circuit pump is kept to zero continues for a predetermined time period or more, open the switching valve and keep the delivery volume of the closed circuit pump to a predetermined delivery volume or more, the predetermined delivery volume being greater than zero.

  • Patent number: 11494739
    Abstract: Message display control means updates and displays messages sequentially on a message list screen each time message receiving means receives a message. When input detection means detects a response message, identification means identifies the latest message at the time of detection and the response message. Response message sending means sends the response message as a response to the identified message to other participants upon completion of input of the response message. Therefore, even in the case where the message list screen is updated due to receiving the subsequent message during the input of the response message, the completed response message is able to be sent back to the response object message.

  • Patent number: 10832568
    Abstract: A method, system, and computer program product for transferring image data taken by an on-vehicle camera. The image data and nearby-vehicle information on a vehicle are received, where the image data and the nearby-vehicle information are successively transferred from each of a plurality of vehicles capable of making a communication with each other. Furthermore, information on a line of vehicles is generated based on the nearby-vehicle information. The image data is then associated with the information on the line of vehicles. Display data may then be generated using the image data. Furthermore, the display data may be presented on a display device in the vehicle.

  • Patent number: 10061661
    Abstract: A computer-implemented method includes running a software unit in an isolation container located on a software platform. The computer-implemented method further includes allocating an instance of a device function instantiated by the software platform to the software unit. The computer-implemented method further includes storing usage data associated with the instance to a memory region logically external to the isolation container, the usage data being generated by the software unit operating the device function. The computer-implemented method further includes detecting a failure of the software unit. The computer-implemented method further includes, responsive to detecting the failure, restarting the software unit and providing the software unit with a usage context, wherein the usage context comprises at least one of identifying information and the usage data associated with the instance stored in the memory region logically external to the isolation container.

  • Publication number: 20150292939
    Abstract: Difference between light intake quantities just from a front and from an upper direction is reduced in an illuminance sensor. A light-guiding member includes a light-guiding member base part, a compound light-guiding part and an infrared light receiving light-guiding part. Side surface parts each extending backward are formed at right and left ends of the light-guiding member base part. The compound light-guiding part includes a front square column part extending frontward from the light-guiding member base part, a back square column part extending backward therefrom, and a round column part extending frontward from the front square column part. A plurality of slits are formed in the light-guiding member base part such that boundaries of base portions of the front square column part and the back square column part communicate with each other.

  • Patent number: 8966458
    Abstract: A virtual machine can be extended to be aware of secondary cores and specific capabilities of the secondary cores. If a unit of platform-independent code (e.g., a function, a method, a package, a library, etc.) is more suitable to be run on a secondary core, the primary core can package the unit of platform-independent code (“code unit”) and associated data according to the ISA of the secondary core. The primary core can then offload the code unit to an interpreter associated with the secondary core to execute the code unit.
