Title: Exposure method, aligner and method of manufacturing device
Inventor: SHIRATA YOSUKE
IPC: G03F7/20
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To enable DP exposure even under conditions under which DP exposure is conventionally impossible. SOLUTION: In this exposure method, an illumination system 12 and a substrate driving system 56 are controlled so that a substrate W is rested at a first position in the direction of an optical axis AX of a projective optical system PL and subjected to exposure with a first light exposure, subjected to a second exposure while being moved from the first position to a second position in the direction of the optical axis continuously and subjected to a third exposure when rested at the second position. At this time, a main control unit 50 adjusts exposure time by adjusting the illumination on the substrate surface. Therefore, the illumination of the substrate surface, that is, the first to third exposures are appropriately set by the main control unit 50 so that the exposure time for each process or the entire exposure time is appropriately set.  Therefore, DP exposure can be performed under optimal exposure conditions even under conditions under which DP exposure is conventionally difficult (combination of resist sensitivity and movement distance of the substrate in the direction of the optical axis).

Title: Superconductive radioactive ray detector
Inventor: MOROHASHI SHINICHI
IPC: H01L39/22
Filed: 1994-03-29
Abstract: PURPOSE:To eliminate the critical current by locating a control line near a Josephson junction and allowing the specified current to flow in the control line. CONSTITUTION:The strength of a magnetic field H near a Josephson junction can be approximated to 1/(2pir), where the distance between a control line 21 and the Josephson junction is 'r' and the current which flows in the control line 21 is 1. When the distance 'r' is about 1mum, the strength of a magnetic field at the Josephson junction when the maximum superconductive current is caused to flow in the control line 21 is 2.4X10<4>/m, which is 300 gausses by the gauss unit system and whose component parallel to the junction face is about 210 gausses. All that has to be done to eliminate the critical current at the junction is to let a magnetic flux corresponding to 1 magnetic flux quantum phi0, pass through parallelly to the junction face. If the thickness of a barrier layer 5 is 2nm and the length of the control line 21 is 50nm, the magnetic flux density of about 207 gausses is required at the junction. Since the magnetic flux density which can be generated by the control line 21 is 210 gausses or below, the critical current can be eliminated by allowing the superconductive current to flow in the control line 21.

IPC: G01J3/02
Filed: 1988-03-14
Abstract: PURPOSE:To make the output waveform by enlarged display or by plotter easier to read, by deleting the spectrum waveform indicated partially by the spectrum waveform within a specified range, and thereupon emitting the output. CONSTITUTION:Those spectrum waveforms corresponding to the contents of a range specifying part 2 which should be deleted are judged by an output spectrum judging part 6.

Vector waveform conforming to l=¦x0-x1¦ is emitted. That is, the spectrum waveform meeting this condition lies within the specified rectangular zone, and the spectra not meeting the condition are partially outside the rectangular zone. In case no spectrum waveform meets the condition, the one with greatest l is emitted.
