The method and device of the present invention for wound treatment includes a transducer to produce waves, preferably ultrasonic waves. The transducer has tip with the distal end (radiation surface). A liquid is directed to the radiation surface wherein an directed atomized particle spray of the liquid is created upon contact of the liquid with the radiation surface. The spray directed to the wound from at least 0.1 inches transmits wave trough particles and has an irrigation, mechanical cleansing, liquid energizing and bactericide effect.

The hydraulic control apparatus of an automatic transmission of claim 1, further comprising: a third valve which is arranged in between the hydraulic source and the first and second control means and which is capable of selectively switching a supply and cutting off of hydraulic pressure to the first and second control means, wherein, the second valve assumes a position to cut off hydraulic pressure to the first hydraulic servo and the first signal pressure to the first valve when the third valve assumes a position to cut off hydraulic pressure to the first and second control means. 3. The hydraulic control apparatus of an automatic transmission of claim 1, wherein the second valve is arranged in an upstream side of a signal pressure supply hydraulic path, a branch of the first hydraulic path, to the first valve. 4. The hydraulic control apparatus of an automatic transmission of claim 1, wherein when the first control means outputs hydraulic pressure and condition changes from an engagement of the first friction element to the second control means ready to output hydraulic pressure enabling supply of hydraulic pressure to the second hydraulic servo, at least predetermined forward speeds are achieved by releasing the second friction element using at least the first valve, and wherein when the predetermined forward speed is a high speed, the first friction element is released at a low speed and is engaged at a high speed, and the second friction element, which is released by hydraulic pressure to the first friction element, is engaged at the low speeds and is released at high speeds. 5. The hydraulic control apparatus of an automatic transmission of claim 4, wherein the second valve is structured in such a manner that hydraulic pressure to the first hydraulic servo which operates the friction element to be released during the low speed time is applied to the second valve, and wherein hydraulic pressure supply state is enabled by running current to the signal pressure generation means when the friction element is engaged, after which the hydraulic pressure supply enable state is maintained even if the current is stopped. 6. The hydraulic control apparatus of an automatic transmission of claim 4, further comprising the third friction element and the third control means for controlling engagement and release by supplying and removing hydraulic pressure
