  • Patent number: 12208489
    Abstract: One array of grindstones is used for in-feed grinding and creep-feed grinding. Therefore, it is not necessary to position a chuck table that is holding a plate-shaped workpiece with respect to two different arrays of grindstones. As a result, a period of time required to grind the plate-shaped workpiece can be shortened. Furthermore, lower surfaces of the grindstones are used for the in-feed grinding, whereas side surfaces of the grindstones are used for the creep-feed grinding. Consequently, the amount by which the grindstones are worn can be smaller than that in a case where the plate-shaped workpiece is ground to a predetermined thickness in only the in-feed grinding or the creep-feed grinding.

  • Patent number: 12017669
    Abstract: A drive force control system controls acceleration of a vehicle accurately in line with an operation of an accelerator pedal to improve an acceleration feel. A controller calculates a corrected target acceleration when a required acceleration is large and an operating speed of the accelerator pedal is fast, and converts the corrected target acceleration into a target driving force to propel the vehicle so as to achieve the corrected target acceleration by generating the target driving force.

  • Publication number: 20230321680
    Abstract: A processing apparatus includes a processing chamber cover having a first transverse member extending from between a first side plate and a first delivery port defined in the first side plate outwardly of a first processing chamber. The width of a gap between the first transverse member and a pedestal positioned in the first delivery port when a workpiece is processed in the first processing chamber, i.e., the length of the gap along the direction toward the outside of the processing chamber, is large. When processing water that is scattered passes through the gap, the processing water will likely contact the pedestal or the first transverse member and stay in the gap. As a result, the processing water is effectively prevented from being scattered out of the first processing chamber by a simple structure, compared with water supply means for forming a water film in the gap.
