  • Patent number: 12128525
    Abstract: A workpiece supporting device (6) includes a base stand (10), a shoe (11) which is disposed on at least one place in a circumferential direction of a workpiece (1a) that is rotationally driven using a rotary drive device (4) and is in sliding contact with a circumferential surface of the workpiece (1a), and a supporting body (12) which supports the shoe (11) with respect to the base stand (10). The supporting body (12) includes a compliant structure portion (a leaf spring (14)) which tilts the shoe (11) in accordance with tilting of the workpiece (1a) with respect to the base stand (10).

  • Publication number: 20240330166
    Abstract: A vehicle control system includes: a computation unit that executes a computation of first control software when a vehicle is in a first state and that executes a computation of second control software when the vehicle is in a second state; a comparison reference data saving unit that saves input data input from a sensor to the first control software and to the second control software and that saves output data from the first control software and the second control software; and an evaluation unit that evaluates the performance of the second control software, based on a difference between pieces of output data read from the comparison reference data saving unit.

  • Publication number: 20240241747
    Abstract: An electronic controller includes: a virtual machine that accesses a first virtual driver to execute a process; a hypervisor that calls a first real driver of a first peripheral, based on a peripheral access request received from the first virtual driver; an access recording unit that calls the first virtual driver to record a peripheral access request transmitted to the hypervisor; a state recording unit that calls the first real driver to record a state of a register of the first peripheral; and a monitoring unit that monitors an operation of the hypervisor. The monitoring unit determines an abnormality of the hypervisor, based on a record by the access recording unit and on a record by the state recording unit.

  • Patent number: 11638976
    Abstract: An oscillating device includes: a driving source; an oscillating member which performs an oscillating motion; and a connecting mechanism which converts a rotational motion of the driving source into an oscillating motion and transmits the oscillating motion to the oscillating member. At least one of a part or whole of a component forming the connecting mechanism is a component made of a fiber-reinforced resin, and the component made of a fiber-reinforced resin includes a reinforced fiber and a binder resin.

  • Patent number: 9914194
    Abstract: Provided is a grinding method capable of preventing variation in the outer diameter of a processed object 1 at the completion of grinding regardless of change in the amount of elastic deformation of the processed object 1 based on the change in the cutting ability of a grindstone 4. The outer diameter D of the processed object 1 during grinding is measured by gauge heads 5 in process. Plural target values Di that differ from each other are set for the outer diameter D of the processed object 1, and first threshold values are set for the rate of change of the outer diameter D of the processed object for each of these target values Di. Spark out is started when the outer diameter D of the processed object 1 becomes equal to a target value Di and the absolute value of the rate of change v is greater than a first threshold value that corresponds to the target value Di.
