Abstract: Method and apparatus for accelerating micro particles for use in delivering DNA or a solid drug in which a shockwave is generated by applying a short pulse energy to a surface of a metal foil to be absorbed and cause vaporization and plasmatization of the metal foil. A jet is generated by a sudden expansion of metal gas and thereby the shockwave is generated on a surface of an opposite side of the metal foil on which the micro particles are arranged.

Abstract: A transfer control method includes a selecting step which selects one of a first route for making an asynchronous transfer to a request destination via a control block and a second route for making a synchronous transfer to the request destination by not passing the control block, with respect to a request from a request source.

Abstract: Shockwave is generated by applying a short pulse energy to a surface of a metal foil to be absorbed and cause vaporization and plasmatization of the metal foil, generating thereby a jet by a sudden expansion of metal gas and thereby generating a shockwave on a surface of an opposite side of the metal foil.

Abstract: Disclosed are a safe and small-scaled shock wave generating apparatus and effective applications of shock wave generated by the device. Provided in the shock wave generating apparatus are a columnar rotation body, a rotation shaft projected from both end faces of the rotation body towards outside in parallel to the lateral surface of the rotation body, a rotation drive unit for providing predetermined torque to the rotation body through the rotation shaft and a controller for controlling operation of the rotation drive unit. The controller has a function of controlling the operation of the rotation drive unit so that at least a part of the lateral surface of the rotation body spins at a speed higher than the sound velocity under a condition near the periphery of the rotation body.

Abstract: An apparatus for disintegrating a calculus in the human body by an underwater shock wave produced outside the human body. The apparatus includes a shock wave generation chamber having an inner surface in the shape of a part of a pseudo-ellipsoid of revolution having an opening therein. Also provided is a shock wave generation source positioned at the first focus of the pseudo-ellipsoid of revolution. In addition, a flexible container housing a liquid is attached to the shock wave generation chamber so that the liquid from the flexible container fills up the shock wave generation chamber. The flexible container containing the liquid is brought into contact with the human body, and the shock wave generation chamber is displaced so as to deform the flexible container, until the calculus in the human body is positioned at the second focus of the pseudo-ellipsoid of revolution.
