  • Patent number: 11680638
    Abstract: The present invention provides a shift control method implemented in a vehicle equipped with an automatic transmission for controlling an input shaft rotation speed to a target input shaft rotation speed during a shift. The method includes setting of a basic target synchronization rotation speed that is a basic target value of the input shaft rotation speed during the shift, and setting of a corrected target input shaft rotation speed as the target input shaft rotation speed when the shift is a downshift without a requirement for a driving force of the vehicle, The corrected target input shaft rotation speed is obtained by decreasingly correcting the basic target synchronization rotation speed. Further, a decreasing correction amount of the basic target synchronization rotation speed is set so as to become larger as a deceleration of the vehicle becomes larger.

  • Patent number: 9368363
    Abstract: The present invention is a plasma etching gas comprising a fluorocarbon having 3 or 4 carbon atoms, the fluorocarbon including at least one unsaturated bond and/or ether linkage, and including a bromine atom, and a plasma etching method comprising subjecting a silicon oxide film on a substrate to plasma etching through a mask using a process gas, the process gas being the plasma etching gas. This plasma etching gas exhibits excellent etching selectivity, and has a short atmospheric lifetime and a low environmental impact. This plasma etching method makes it possible to selectively subject a silicon oxide film to plasma etching at a high etching rate without causing an increase in surface roughness.

  • Patent number: 9302306
    Abstract: Provided is a technique which can, in order to guarantee the molding accuracy of hot press molding, accurately measure the temperature of a workpiece being subjected to the hot press molding. A hot press mold is a mold used for hot press molding for hardening and molding a workpiece, which has been heated, by pressing the workpiece. The hot press mold is provided with a stroke type temperature measuring device which is extended and retracted by a pressing force applied thereto through the workpiece. The temperature measuring device is provided in such a manner that the temperature measuring device protrudes outward from the molding surface of the mold, and when subjected to the pressing force applied through the workpiece while being in contact with the workpiece, the temperature measuring device shortens in length and retracts into the mold.
