  • Patent number: 11273820
    Abstract: A hybrid vehicle includes a connecting/disconnecting clutch disposed between an engine and an electric motor, an automatic transmission including an input clutch, a starting clutch disposed between the electric motor and the automatic transmission, and a control apparatus for executing an engine-start control operation for starting the engine, by igniting the engine after increasing a rotational speed of the engine by a torque of the electric motor while placing the connecting/disconnecting clutch into an engaged state. In process of the engine-start control operation that is executed when the hybrid vehicle is in a stopped state with the starting clutch being in a released state, the control apparatus places the input clutch in an engaged state until the rotational speed of the engine exceeds a predetermined speed value, and switches the input clutch to a released state after the rotational speed of the engine has exceeded the predetermined speed value.

  • Patent number: 10499648
    Abstract: A sterilization method is provided which acquires microbicidal activity equivalent to plasma-treated solution or more powerful than the same without the use of a plasma generation device. The sterilization method includes applying liquid containing peroxynitric acid (HOONO2) produced by chemical reaction to an object to be sterilized under acidic conditions of a pH value of 4.8 or lower. The liquid containing the peroxynitric acid is produced by mixing nitrous acid and peroxide together, for example, mixing nitrite and peroxide together.

  • Publication number: 20160074829
    Abstract: An apparatus includes a pipe line, water supplying devices, gas supplying devices, a plasma generation device, a cooling device for cooling water flowing in the pipe line, and a vessel. The plasma generation device has a high-voltage electrode and a ground electrode which are provided outside the pipe line to face each other with the pipe line interposed therebetween and applies a plasma treatment continuously to the water flowing in the pipe line by generating dielectric barrier discharge between the high-voltage electrode and the ground electrode. The cooling device cools the water to have a low temperature of 10° C. or lower. The plasma treatment is applied to generate a plasma-treated solution in which superoxide anion radicals (O2?.) or a precursor thereof is diffused in the water and a microbicidal activity is sustained.

  • Patent number: 9050963
    Abstract: A map is provided that has an unlimited region where a take-off slip-engagement the next time is repeatedly executed indefinitely, a limited region where the take-off slip-engagement the next time is repeatedly executed only once, and a prohibited region where the take-off slip-engagement the next time is prohibited, and has a generated heat amount during the take-off slip-engagement and an elapsed time after the lock-up slip-engagement ends as variables. Therefore, a region in which the take-off slip-engagement the next time had been prohibited because the take-off slip-engagement the next time is unable to be repeatedly executed indefinitely even though it is able to be repeatedly executed only once is made the limited region, so the take-off slip-engagement the next time is allowed to be repeatedly executed only once.
