Abstract: An X-ray imaging device and an auxiliary positioning system thereof, include a first display, a second display and a camera. The first display is used for displaying a standard position to a patient. The camera is used for acquiring a position image of the patient, and transmitting the acquired position image to the second display. The second display is used for displaying an overlap graph between the position image of the patient and an automatic exposure control domain, as well as a collimator opening domain of a collimator. With the first display displaying a standard position to a patient, the patient may quickly and intuitively know the optimal position, which reduces the time needed for an operator to give explanations to the patient.

Abstract: This invention relates to a method for the inhibition of the growth of undesirable microorganisms on fruit, vegetable, turfgrass and other plant systems by the application of specific enzymes either alone or in combination with fungicidally active agents.

Abstract: The present invention relates to a method and apparatus of manufacturing nickel-metal-hydride alloy powder material. The furnace charge of nickel-metal-hydride alloy is melted in vacuum or argon atmosphere in this invention. After melting, the molten alloy is gas atomized to fine spherical powder or centrifugal atomized to flaky shape. Then the powders are fed into a hydrogen heat treatment chamber for hydrogen heat treatment and pulverization. This invention integrates the melting, pulverizing and hydrogen treatment of nickel-metal hydride alloy powder into a whole step. It can charge and pulverize continuously and is suitable for the large-scale industrialized production of homogeneous composition and least segregation nickel-metal hydride alloy powder.
