  • Patent number: 11892077
    Abstract: A vehicle gear-shifting control apparatus is equipped with an engine, an automatic transmission, and a controller which changes a shift stage by outputting a gear-shifting signal in accordance with the rotation speed of an input shaft to the automatic transmission. The controller executes a torque-regulating control of temporarily increasing or decreasing an input torque input to the input shaft during a shift-change, and when executing the control, determines whether or not a target increase/decrease amount of the input torque can be realized based on calculation results of a target output torque and a target gear-shifting time, executes the control to realize the target amount when it is determined that the target amount can be realized, and executes the control based on an allowable gear-shifting time set in advance to be longer than the target gear-shifting time when it is determined that the target amount cannot be realized.

  • Patent number: 11501998
    Abstract: There is formed, on a stack formed by alternately stacking an oxide film and a nitride film or an oxide film and a polysilicon film on a substrate, a hard mask in which two or more kinds of lines made of mutually different materials are arranged in order. Then, a photoresist is applied onto the hard mask. Furthermore, the photoresist is trimmed until one line is exposed from the end of the hard mask. Moreover, one line of the hard mask exposed beneath the photoresist is etched. Furthermore, a part of the stack exposed beneath the hard mask is etched. The etching of the photoresist, the hard mask, and the stack is repeated while changing etching conditions.
