Abstract: PURPOSE: To clean only a microchip without exerting effect on other element part by using a vacuum chamber housing a microchip part. CONSTITUTION: After a vacuum chamber 11 is evacuated by a vacuum pump 15, a probe 22 is laterally irradiated with ArF laser 12. At this tide, a support stand 14 is rotated and the entire periphery of a microchip 8 is irradiated with the laser 12. When O2 gas is introduced into the chamber 11 from a gas introducing port 13, O-radicals are formed from O2 by the energy of the laser 12 and the org. contaminant of the microchip 8 is dissociated and the reaction product with the O-radicals is discharged. Finally, the irradiation with the laser is stopped and the probe 22 is allowed to approach a sample 21 under vacuum to scan an X-Y stage 23 and voltage is applied across the microchip 8 and the sample 21 from a bias voltage applying circuit 27. The tunnel current observed at this time is read by a detection circuit to observe an image.  The sequence control of these operations is performed by a CPU 26.

IPC: G21F9/02
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To securely collect the radioactive iodine produced in nuclear power plants and facilities for reprocessing spent nuclear fuels by using an iodine removal filter comprising a macromolecular material that, on a main chain, has polymer side chains containing units derived from N-alkyl-N-vinylalkylamide and the like. SOLUTION: An iodine removal filter comprising a macromolecular material is used in order to adsorb and remove iodine. Side chains in the form of polymer chains containing units derived from N-alkyl-N-vinylalkylamide at least are located on a macromolecular main chain of the macromolecular material. A radiation-induced graft polymerization method is adopted as a means for introducing the side chains in the form of such polymer chains. Moreover, macromolecular material fiber and woven or unwoven fabric as its aggregate can be utilized as a material used as a base for introducing the side chains of the polymer chains. A base made of woven and unwoven fabric, which is lightweight and easy to work into a filter, can remove not only a noxious gas ingredient but also particulates.

Filed: 1984-03-28
Abstract: PURPOSE:To relieve the load of data processing of a microprocessor unit using a mode designation circuit discriminating a required instruction out of plural data instructions and switching automatically the operating mode to the instruction even in case of the automatic increment of an X axis address. CONSTITUTION:A mode designation circuit 31 latches a 1-bit mode identification data in the timing of a latch pulse L4. When the result of mode identification is the signal processing mode of the proportion/differentiation/integration system, the circuit 31 selects a changeover switch 32 and feeds the result to a write timing pulse generating circuit 17. On the other hand, when the mode identification result is the signal processing mode of the photographic system, the circuit 31 controls are changeover switch 32, the switch 32 selects a latch pulse L3 and supplies the result to the circuit 17. Thus, a required data descripiton instruction is discriminated and the mode is switched automatically in the operating mode suited to the instruction. In case of the automatic increment of the X axis address, the data processing load of the microprocessing unit is retrieved.

Abstract: PURPOSE:To provide a magneto-optical disk device capable of easily reducing leakage magnetic field in a laser beam focal position on a magneto-optical disk. CONSTITUTION:This device is provided with first focus magnets 100a, 100b and second focus magnets 101a, 101b for driving an objective lens l irradiating a laser beam on the magneto-optical disk 2 in a focus direction, and the thickness of the first focus magnets 100a, 100b of a side far from the magneto-optical disk 2 is formed larger, and the thickness of the second focus magnets 101a, 101b of the side close to the magneto-optical disk 2 is formed smaller, and directions of magnetization are constituted inversely respectively.
