  • Publication number: 20240094624
    Abstract: According to one embodiment, a pattern formation method includes holding a substrate on a suction chuck that an outer suction region for an outer edge portion of the substrate and an inner suction region for an inner region of the substrate. A partial shot region at an outer edge of the substrate has a first alignment mark in the inner region and a second alignment mark at the outer edge portion. While a template is being pressed against a resin film in the shot region, position alignment using the second and fourth alignment marks is performed by adjusting a suction force for the outer suction region for changing a warpage amount of the substrate while observing the second and fourth alignment marks through the template.

  • Patent number: 11899360
    Abstract: An imprinting method includes placing a template onto non-solidified resin that is applied onto a surface of a substrate, such that the non-solidified resin extends into a pattern of the template in a surface direction of the substrate, starting first alignment operation to align the template with the substrate using a first alignment mark at a first timing, and starting a second alignment operation to align the template with the substrate using a second alignment mark at a second timing after the first timing. The first timing is when the non-solidified resin has extended into the first alignment mark and not yet into the second alignment mark. The second timing is when the non-solidified resin has extended into the first and second alignment marks.

  • Patent number: 9694821
    Abstract: An upper limit value of an upward gradient of a road surface for starting neutral coasting is set to be larger than an upper limit of the upward gradient of the road surface for starting free-run coasting, so, when the upward gradient is relatively large and a coasting distance is short, the vehicle is caused to travel in the neutral coasting, and stop and restart of the engine are not carried out. Therefore, a decrease in drivability of the vehicle is suppressed. When the upward gradient is relatively small and the coasting distance is long, the vehicle is caused to travel in the free-run coasting, and supply of fuel to the engine is stopped, so fuel economy of the vehicle is obtained. Thus, it is possible to achieve both fuel economy and drivability of the vehicle during coasting on an upward gradient.

  • Patent number: 9598084
    Abstract: A running control device of a vehicle executes a normal running mode with an engine coupled to drive wheels, a first inertia running mode with the engine stopped during running and an engine brake force reduced as compared to the normal running mode, and a second inertia running mode with the engine rotating during running and the engine brake force reduced as compared to the normal running mode. A determining portion determines a necessity of a brake negative pressure during the first or second inertia running mode. The necessity of the brake negative pressure is a condition for returning from the first inertia running mode and the second inertia running mode to the normal running mode. An upper limit value of the necessity of the brake negative pressure for returning from the first inertia running mode is smaller than that for returning from the second inertia running mode.
