Abstract: An X-ray CT scanner comprises a plurality of X-ray generators which are arranged radially on a circle concentric with an object for measurement and each consists of a cathode electrode, an anode electrode constituting a target and a grid between the cathode and anode electrodes. For X-ray tomography, X-rays are projected onto the objects from the circle concentric therewith by sequentially temporarily removing a bias voltage applied to the grids of the respective X-ray generators for suppressing an electron beam directed from the cathode electrode to the anode electrode of each X-ray generator.

Abstract: The present invention provides a printing device wherein a sublimable dyestuff contained in a dyestuff case is heated to sublime to form steam of the dyestuff into which gas is flowed in order to pressurize the dyestuff steam to form pressurized dyestuff steam. A nozzle plate having a nozzle formed therein for jetting the pressurized dyestuff steam toward a record medium is communicated in a closing up relationship with the dyestuff case, and a valve for opening and closing the nozzle is provided at a deformable portion of a valve beam. An electrode plate is provided in an opposing relationship to the valve and in an isolated relationship from the valve and the pressurized dyestuff steam. The valve is displaced by an electrostatic force caused by a difference in potential between the valve and the electrode plate to close the nozzle. By selectively opening the nozzle, the pressurized dyestuff steam at a high pressure is jetted from the nozzle to effect printing.

Abstract: A deodorizing coating formulation is composed of a white or substantially colorless deodorizing agent, a binder resin and a liquid medium. The deodorizing agent may preferably be composed of 10-90 parts by weight of a zinc compound and 90-10 parts by weight of an aliphatic polycarboxylic acid, aromatic polycarboxylic acid, acidic polymer or a sulfate of aluminum, or a salt thereof. A deodorizing sheet can be obtained by coating and/or impregnating a base sheet with the deodorizing coating formulation and then drying the resulting base sheet. The deodorizing sheet can shield a flavor or odor from external flavors or odors while maintaining air permeability, it is suitable for wrapping foods having strong flavors or odors.

Abstract: A communication system employing a multi-conjunction architecture has a supervising circuit for supervising whether or not a returning signal is received from a destination terminal device in response to a sending signal. When no returning signal is detected within a specific time after the sending signal is transmitted, a communication path used for transmitting the sending signal is isolated from rest of the communication system, or a pseudo returning signal is outputted from the supervising circuit to fix a communication path used for transmitting the sending signal and the pseudo returning signal. As a result, communication paths other than that used for transmitting the sending signal may be used for other communications when the returning signal is not detected for the specific time.
