Abstract: PURPOSE:To adjust an ink jet direction in a uniform manner and at a prearranged precision by arranging an electric charge detection stand having an indication circuit in the neighborhood of a printing surface and stopping adjustment of a deflected ink jet direction when the indication circuit indicates a detected electric charge. CONSTITUTION:An electrode stand 1 equipped with a plural number of wire- shaped or bar-shaped electric charge detection electrodes 21, 22, 23... arranged in a  deflection direction at a prearranged pitch, is installed near a printing surface.  Electric charge detection circuits 51... are connected to the electric charge detection electrodes 21.... While indication circuits 71... are connected to the electric charge detection circuits 51.... Ink ejected from an ink jet nozzle 93 will be electrically charged, a deflection field be reduced to nothing and FET be closed instaneously. Then pins 193, 203 will be turned so that the ink jet direction may be slided toward a deflection direction. If a luminous diode Dp1 becomes luminous, that signifies that ink particles collide with the electric charge detection electrode 23 and a deflected ink ejection direction is appropriate.

Abstract: PURPOSE:To improve the workability of target member exchanging work, to continuously generate X rays for a long time, and to reduce the size and cost of a vacuum vessel by providing an introducing section and vacuum holding means to a target supplying means and the vacuum vessel. CONSTITUTION:Rubber rollers 110a and 110b are formed of an elastic material and tightly attached to the surface of a tape-like target 109 without gap so as to substantially prevent the flowing of air, etc., into a vacuum vessel from the contact areas of the rollers 110a and 110b.

In addition the target 109 can be replaced without stopping an X-ray generator by replacing a reel 102 and all and additionally connecting a new target 109 to the end of the old tape. Since a vacuum vessel 101 has a remarkably small internal volume and the relative performance of a vacuum pump is improved, the inside of the vessel 101 is substantially maintained in a vacuum stage even when a very small amount of air, etc., flows in the vessel 101 from the contact areas of the rollers 110a and 110b.

Title: Current-injection-logic synchronous driving circuit
Inventor: TONII TAKESHIAN
IPC: H03K19/091
Filed: 1992-02-18
Abstract: PURPOSE: To provide an IIL synchronous driving circuit with fan-out capability which is improved without causing equivalent timing skew between an input signal and output signals. CONSTITUTION: The current injection logic synchronous driving circuit generates output signals through logic gates 24 and 34 according to one input signal 12. The logic gates 24 and 34 have their inputs connected in common by a common gate 26 and are then connected in parallel. A current source 30 supplies a current to a 1st logic gate between the logic gates 24 and 26, the driving circuit supplies a driving level which is sufficient for the common node 26 of the inputs of the logic gates 24 and 34 according to the input signal, and the logic gates 24 and 34 sink currents equal to the specific current from the current source 30. Thus, the synchronous driving circuit generates the output signals in the same logical states to increase the fan-out to other logic circuits of the system.  The propagation delay of the synchronous driving circuit is small because of the parallel connection of the logic gates having common drive.
