Abstract: A multisource type X-ray CT apparatus including a fixed sensor array, a fixed vacuum chamber, and an X-ray generation unit. The X-ray generation unit includes a cathode and an anode which are fixed in the vacuum chamber so as to surround the sensor array, a gate array including a plurality of grid electrodes which are densely fixed between the cathode and anode and which include holes for passing the electron beams, a power source which applies a bias voltage to the grid electrodes of the gate array, and a controller which controls the power supply operation from the power source so as to select the grid electrode suitable for image pickup from the gate array in accordance with an image pickup portion of the subject and to release the bias voltage applied to the selected grid electrode.

Abstract: An X-ray CT apparatus comprises a large number of X-ray sources, a detector, and a collimator. The X-ray sources are arranged around an object P of inspection. The detector detects X rays emitted from the X-ray sources. The collimator is located between the X-ray sources and the object of inspection, and restricts the angle of emission of the X rays emitted from the X-ray sources so as to match the size of the detection surface of the detector.

Abstract: An X-ray CT apparatus according to the present invention comprises a plurality of X-ray generating means which generate X-rays, surround a measuring object, are arranged on a circle with the measuring object at the center, and are relatively movable with respect to the measuring object, a detector which surrounds the measuring object, is arranged on a circle with the measuring object at the center, is relatively movable with respect to the measuring object, and detects X-rays emitted from the X-ray generating means and transmitted through the measuring object, and X-ray generation controlling means which selects use/non-use of each of the X-ray generating means, and a mode setting directing means for directing a desired operation mode with respect to the X-ray generation controlling means.

Abstract: In a booster type high-pressure container including an outer cylinder associated with upper and lower lids and an inner cylinder fitted in the outer cylinder with a gap clearance retained therebetween, a booster chamber is provided between a piston disposed within the inner cylinder at its bottom portion and the lower lid of the outer cylinder, a boosting liquid medium is injected into the booster chamber for pushing up the inner cylinder jointly with the piston to boost the pressure within the inner cylinder, and the gap clearance communicates with the booster chamber.

Abstract: The present invention relates to a cassette-type printing head which comprises in combination: a cassette body for housing an ink, an ink guiding member in which one end portion thereof is immersed in the cassette body, and a film member having a plurality of holes or recesses for housing an ink which is contacted by the ink guiding member which protrudes from the cassette body.

Abstract: At least one pulley member which is rotatably positioned in said casing member; a film member which is movably contacted with a heating surface of a thermal head and is movably guided by said pulley in said casing member; a plurality of small holes which is shaped to said film member; a recording ink which is stored in said casing member; said pulley and film members are immersed in said recording ink; said recording ink is housed in said small holes; said recording ink in said small holes of said film member is moved to a corresponded position to a heating surface of said thermal head by rotating said pulley member and moving said film member according to a rotation of said pulley member.

Abstract: A printing machine is provided, comprising a thin film having first and second surfaces connected by a plurality of hole or recess portions and movably positioned; an ink tank for supplying ink to the hole or recess portions; a thermal head member having a plurality of thermal head elements in contact with the first surface of the film; a driving circuit for selectively driving the thermal head elements; and a recording paper feeding mechanism to feed recording paper adjacent the second surface of the film. The ink fills the holes or recess portions, and the thermal head element is selectively driven by the driving circuit when one thermal head element corresponds to a plurality of holes or recesses of the film, whereby ink is sprouted or jetted from a plurality of the holes or recesses onto the recording paper by bubble pressure caused by heat from the thermal head element. Color printing is also possible with the apparatus of the invention.

Abstract: Difficult flushing of a very narrow gap between a first member having a bore with a closed end and a second member inserted and fixed in the bore can be easily achieved by connecting the gap with a container filled with a pressurized flushing liquid and locally heating the closed end of the gap. Preferably, while locally heating the blocked end of the gap the pressure of the pressurized liquid is reduced to cause the liquid to boil, and if necessary, the pressurizing and pressure reduction are repeated to enhance the flushing effect.
