摘要： The present invention relates to SPM nanoprobes and the preparation method thereof, more particularly, to SPM nanoprobes comprising a spheroid deposit capped-nanoneedle bonded to one end of a mother tip, wherein the spheroid deposit is formed by particle beam induced deposition and is characterized in that the ratio of the diameter of the spheroid deposit to that of the nanoneedle is in the range of 1.5 to 8.5. The SPM nanoprobe according to the present invention is capable of imaging or measuring an irregularly curved or complicated surface, pattern and/or a frictional or adhesive force thereof and controlling size of a spheroid deposit formed at the end portion of nanoneedle and the ratio of the diameter of the spheroid deposit to that of the nanoneedle arbitrarily.

摘要： A display apparatus for displaying pictures virtually instantaneously adopts a direct-heating type cathode of an impregnated structure, and includes a cathode ray tube having a dispenser cathode wherein a cathode material is filled in pores of a porous body and a porous heater is directly connected to the cathode material. A voltage generator of the apparatus produces a first voltage for driving the heater. A video signal supply portion supplies a video signal to the cathode, while a deflector deflects horizontally and vertically an electron beam generated from the cathode to produce a raster by scanning the fluorescent surface of the cathode ray tube. A flyback transformer generates a second voltage to be supplied to the anode and one or more grids of the cathode ray tube using a horizontal deflection output signal supplied from the deflector. With the described arrangement, an electron-emitting velocity of an electron gun reaches its maximum value within about one second after power is applied. Thus, the display apparatus can be adapted to an HDTV requiring high current density electron-emitting characteristics.
