Title: Optical information recording method
Inventor: GOTO NORIO
IPC: G11B7/0055
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To improve an erasure ratio by providing a multiple interference film adjacent to a recording film for utilizing a phase change on a substrate, allowing a function indicating the relationship between the power of laser beams being applied to the recording film and the reflection factor of an irradiation part where reproduction laser beams are applied to have an extreme value, and applying laser beams with a power where the reflection factor becomes the extreme value and crystallizing the recording film. SOLUTION: In an optical disk 20, an AIN film, an INSbTe phase change film, an Au film, and the AIN film are formed as a first interference film 6', a recording film 7, a reflection film 8, and a protection film 9, respectively, on a transparent glass substrate 5 by sputtering. A recording laser power operating point is set to 14mW. When an erasure laser power is set to 8-10mW where a reproduction laser beam reflection factor becomes an extreme value, the reproduction laser beam reflection factor does not change even if the degree of crystallization on erasure slightly changes, thus suppressing unerasure (a slight change in the degree of crystallization) on overwriting and improving an erasure ratio.

Title: Hydraulic type wrapper roll
Inventor: HONJIYOU HISASHI
IPC: B21C47/06
Filed: 1979-02-05
Abstract: PURPOSE: To decrease the impact due to thickness difference and to prevent the vibration of a press frame quickly, by moving the press frames of wrapper rolls stepwise by an air cylinder means, and by forcing back push-and-pull rods simultaneously.  
     CONSTITUTION: Just before the top of a strip 4 passes wrapper rolls 7, the rolls 7 are forced back by a distance equal to the plate thickness by drawing off the air from an air cylinder means 9 according to the ON-OFF timing command signal 34. When the top of a second turn lapping over the tail of the first turn (a portion having plate thickness difference) passes the rolls 7, the rolls 7 are forced back in the simmilar way. Following these operation, rods 10 moves gradually together with pistons 15 in the direction opposite to the press frame 2, and the pistons 15 come into contact with stop means 29 at the time when the plate thickness difference becomes relatively small because of the increase in the number of turns of the strip 4, then the rods 10 only are moved. Even if the frames 2 begin to vibrate, the vibration is decreased and stopped completely in its early stage by throttle valves 26, 28.

Title: Scanning aligner
Inventor: OOUCHI CHIGUSA
IPC: G03F7/20
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To provide a scanning aligner capable of accurately measuring an illumination flutter in an orthogonal direction of scanning substrate by setting a mask with its transmittance of each section of an orthogonal scanning direction which is inversely proportional to the sensitivity of the corresponding position on the light-receiving face of a photosensor. SOLUTION: A sensitivity control mask 12, with transmittance of each section of an orthogonal scanning direction inversely proportional to the sensitivity of the corresponding position of the photo sensor 12, is set on the light-receiving face of a photosensor 11. Since the width of an opening slit of the sensitivity control mask 12 is set inversely proportional to the sensitivity on the position corresponding to the photosensor 11, the sensitivity of the photosensor 11 can be compensated to the scanning direction 16 of a stage 9, that is, with respect to the lengthwise direction of the slit. Even if an illumination flutter in a scanning direction 16 of the exposure light exists, an output proportional at the exposure of wafer exposure can always be obtained from the photosensor 11. This enables improvement in the accuracy of exposure control and image focussing performance.

IPC: H01J37/08
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To stabilize an ion current by introducing oxygen to the vicinity of a liquid metal ion source, guiding the secondary electrons from an optical part irradiated by discharged ions to the liquid metal ion source and removing impurities on the liquid metal surface. SOLUTION: When a discharged ion current becomes unstable, oxygen is introduced from a gas cylinder 10, by applying a potential negative to an extraction electrode 3 to a beam limiting aperture 4, most of the secondary electrons generated in the aperture 4 pass a hole 6 and rush in a emitter. The quantity of generated secondary electrons is approximately equal to that of the irradiation ion current. As a result of the interaction between the electrons generated by positive irradiation of the emitter and the introduced oxygen, an insoluble film including carbides as the main component formed on the liquid metal surface is decomposed and removed so that a clean liquid metal surface can be exposed. In this way, the tailor cone is stabilized both in position and time and a discharge ion current is stabilized.
