  • Patent number: 9670868
    Abstract: When a first automatic stopping condition is established while a vehicle (1A, 1B) is stationary or a second automatic stopping condition is established during travel, an internal combustion engine (2) of the vehicle is automatically stopped. The first automatic stopping condition is established when a battery voltage or a battery state of charge of a battery (21) equals or exceeds a first threshold, and the second automatic stopping condition is established when the battery voltage or the battery state of charge of the battery (21) equals or exceeds a second threshold. By setting the second threshold to be greater than the first threshold, opportunities for automatically stopping the internal combustion engine (2) are secured while satisfying a power requirement of an electrical load (26, 27) during restarting of the internal combustion engine (2).

  • Patent number: 9662874
    Abstract: After the end of a preceding print job, a printing press is stopped, and ink form rollers (6-1 to 6-4) of an ink roller group (6) are thrown off. After that, a printing plate (7) is exchanged with a printing plate (7?) of a next print job, and a blanket (91) mounted on a blanket cylinder (9) is cleaned. The opening amounts of ink fountain keys (4-1 to 4-n) corresponding to the image of the printing plate (7?) of the next print job are obtained. The obtained opening amounts of the ink fountain keys (4-1 to 4-n) are corrected by correction values of the opening amounts of the ink fountain keys (4-1 to 4-n) considering the influence of cleaning of the blanket (91) to obtain corrected opening amounts. In a state in which the opening amounts of the ink fountain keys (4-1 to 4-n) have been set to the corrected opening amounts, a corrected ink film thickness distribution corresponding to the image of the printing plate (7?) of the next print job is formed on the ink roller group (6).
