A magnet having an annular coolant fluid passage is generally described. Various examples provide a magnet including a first magnet and a second magnet disposed around an ion beam coupler with an aperture there through. The first and second magnets each including a metal core having a cavity therein, one or more conductive wire wraps disposed around the metal core, and an annular core element configured to be inserted into the cavity, wherein an annular coolant fluid passage is formed between the cavity and the annular core element. Furthermore, the annular core element may have a first diameter and a middle section having a second diameter, the second diameter being less than the first diameter. Other embodiments are disclosed and claimed.

Annular cooling fluid passage for magnets

A magnet having an annular coolant fluid passage is generally described. Various examples provide a magnet including a first magnet and a second magnet disposed around an ion beam coupler with an aperture there through. Each of the first and second magnets including a metal core having a cavity therein, one or more conductive wire wraps disposed around the metal core, and an annular core element configured to be inserted into the cavity, wherein an annular coolant fluid passage is formed between the cavity and the annular core element. Furthermore, each annular core element may have a first diameter and a middle section having a second diameter, the second diameter being less than the first diameter. Other embodiments are disclosed and claimed.

An ultrasound diagnostic device is provided which is portable, small, light weight and easy to use. Preferably, the ultrasound diagnostic device is very small and light weight. The weight of the ultrasound diagnostic device normally will be approximately 6 or 7 pounds, including electrical control circuitry, a battery pack, a carrying strap and a transducer assembly. The ultrasound diagnostic device is similar in design to a laptop computer, except that it is smaller than typical laptop computers. The ultrasound diagnostic device comprises a console portion and a display portion. To open the device, the user simply flips open the display portion by lifting up on the display portion at a location near the front end of the device. The display portion is in a hinging relationship with the console portion so that when the user lifts up on display portion, the display portion is rotated upwards and away from the console portion. A transducer assembly is attached to the ultrasound diagnostic device and comprises a transducer cable, a transducer handle, a transducer and a transducer connector. The transducer connector comprises a latch which engages a mating mechanism comprised in a receptacle formed in the console portion. The connector enables different types of transducer assemblies to be implemented with the ultrasound diagnostic device, depending on the bodily feature being imaged. The ultrasound diagnostic device may be adapted to be harnessed with a carrying apparatus, e.g., a strap assembly, which enables the user to carry the device in a manner similar to the manner in which a person carries a camera around his or her neck. The user may operate the device when it is strapped to the user's body. The ultrasound device may include a handle to facilitate hand carriability.

A nozzle for an ink-jet printer is provided. The nozzle is manufactured from a heat-softenable tube and has a gradually converging inner diameter leading to an orifice less than 30 microns in diameter and an outer nozzle diameter proximate the orifice at least as great as the outer diameter at other points along the tube. The nozzle is produced by heating a short segment of a heat-softenable tube while rotating it, until said segment is sufficiently softened to cause the inner diameter to converge at an angle between 5 and 25 degrees with respect to the axis of symmetry of the tube, and until the inner diameter is equal to or less than a selected orifice diameter. The gradual taper is achieved solely as a result of heat-activated surface forces inherent in the tube material and without external drawing or pulling of the tube. Further the gradual taper facilitates achieving a desired orifice dimension during removal of a portion of the tube having an inner diameter less than the selected orifice diameter. The extremely small orifice size enables an ink-jet printer to deposit droplets of ink sufficiently small to make photographic-quality gray scale and color images. Such a nozzle can also advantageously be used for biological, medical and pharmaceutical apparatuses and devices.

Ink jet nozzle

A nozzle for an ink-jet printer is provided having a gradually converging inner diameter leading to an orifice less than 15 microns in diameter and having an outer nozzle diameter proximate the orifice at least as great as the outer diameter at other points along the nozzle. The nozzle is produced by heating a vitreous tube while rotating it, until a portion of the tube is sufficiently viscous to cause the inner diameter to converge at an angle between 5 and 25 degrees with respect to the axis of symmetry of the tube, and until the inner diameter is less than a selected orifice diameter. The gradual taper is achieved without drawing or pulling the tube and it facilitates achieving a desired orifice dimension during removal of a portion of the tube having an inner diameter less than the selected orifice diameter. The extremely small orifice size enables an ink-jet printer to deposit droplets of ink sufficiently small to make photographic-quality gray scale and color images.
