    摘要: A soft x-ray imaging device is disclosed having a housing defining a housing chamber. A faceplate having a planar surface is secured to the housing so that the planar surface is positioned within the housing chamber. A phosphorus coating is applied to the planar surface of the faceplate for convening electrons to visible light. A microchannel plate for convening x-rays to electrons is secured within the housing chamber so that the microchannel plate is spaced from and parallel to the planar surface of the faceplate. An opening is formed in the housing in alignment with the microchannel plate and this opening is sealingly closed by a window which is made of a material substantially transparent to soft x-rays. This window also creates a vacuum tight housing chamber which is continuously evacuated by a pump.

    摘要: An electrical discharge machining apparatus is disclosed having a frame with a base and a vertical support secured to and extending upwardly from the base. A tank adapted to contain an electrolytic liquid is secured to the vertical support by an adjustment mechanism which enables the vertical position of the tank to be varied. A work holder is optionally pivotally secured to the top of the vertical support and movable between a work position in which the work support and work are aligned with the tank and an inspection position in which the work holder is laterally spaced from the tank. Electrical discharge electrodes are contained within the tank while a servo motor vertically moves the work support with its attached work against the electrodes to perform the machining operation. The electrical discharge apparatus is particularly suited for dental prosthesis applications.

    摘要: A soft x-ray imaging device is disclosed having a housing defining a housing chamber. An optic post having a planar surface is secured to the housing so that the planar surface is positioned within the housing chamber.

A microchannel plate for converting x-rays to electrons is secured within the housing chamber so that the microchannel plate is spaced from and parallel to the planar surface of the optic post.
