Abstract: PURPOSE:To provide a low loss and good resistance to radiation by specifying the respective refractive indices of a core, clad and elliptical jacket and the size in the prescribed part at specific values and forming the clad of silica glass contg. fluorine and B2O3. CONSTITUTION:An optical fiber for maintaining plane of polarization has the relation expressed by the inequality I where the respective refractive indices of a core 21, a clad 22 and an elliptical jacket 23 are designated as n1, n2, n3 and has the relation expressed by the inequality II where the radius of the core is designated as T, the thickness of the clad as delta1T, and the total min. thickness of the clad and the elliptical jacket as delta2T. Such relations are obtd. by forming the core 21 and the support 24 of high purity silica, making the clad 22 into the constitution consisting essentially of SiO2 and contg. fluorine and B2O3 and making the jacket 23 into the constitution consisting essentially of SiO2 and contg. P2O5 and B2O3. A low loss and good resistance to radiation are thus obtd.

Title: Electron-beam generating device
Inventor: MOCHIZUKI KATSUKUNI
IPC: H01J37/24
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To reduce the fluctuation of current due to an insulation leak. SOLUTION: In an electron-beam generating device, a sample-and-hold signal consisting of a sample signal S having a sampling period much shorter compared with the hold period (a few tens of seconds to several minutes) and a hold signal H, is sent from a sample-and-hold signal generating circuit 14 to a sample-and-hold amplifier 13. A voltage corresponding to a current flowing through a closed circuit sent to the sample-and-hold amplifier 13 is sampled only during the much shorter sampling period and sent to an amplifier 10 for control, but not sampled during the longer hold period until the next sampling period. The amplifier 10 for control controls a bias power supply 8 only by the voltage sent during each sampling period.

Title: Charged beam lithography
Inventor: YAMAZAKI SATOSHI
IPC: G03F7/20
Filed: 1993-03-15
Abstract: PURPOSE:To write a character figure form selected by a forming deflection system, in a desired lithography position, by a method wherein, when the form of the outer frame of a minimum unit figure is not rectangular, the minimum unit figure is so changed that the minimum unit figure of a repetition pattern becomes rectangular, and the minimum unit figure is formed into an aperture. CONSTITUTION:A repetition pattern 2 is to be written. The minimum unit of the repetition pattern 2 is a parallelogram, and an angle theta is not equal to 90 deg.. Since the form 18 larger than the maximum character beam size of an equipment, the form can not be made the character form as it is. As a result, the form of a figure turning to the repetiton minimum unit 3 is changed. The excess and the lack of patterns 94 are previously considered and designed by using a peripheral circuit pattern. The size of a changed form is 5mm square on the specimen surface, which size is smaller than or equal to the maximum character beam size of the equipment. Thereby the changed form can be defined as the character form.

When recording on the last page, cutting of the recording medium at the last page and rewinding of a cut end part are performed, the cut recording medium 1 is fed until it becomes impossible to detect the medium 1 by a recording medium sensor 6. When it is detected that the trailing end of the last page of the recording medium 1 thus cut is passed through the position of the sensor 6, a feeding roller 7 is reversely rotated until the recording medium 1 is again detected, and it is indicated on an indicator that the recorded recording medium is present on a stacker 20. Accordingly, it is possible to inform an operator of the presence of the recorded recording medium through a simple and inexpensive means.

Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent whitening and erasure after an in-void processing in an original with a light color surface by converting data of an in-void area into surface data. SOLUTION: In a compositing part 403, an averaging part 1307 averages data around white in the original and output data of the averaging part 1307 becomes white data in the area, except the white region. White also includes a light hue. An averaged white output is obtained in the in-void area which is an original image position (a high density area) by the averaging processing. Therefore, the in-void processing is executed by leaving the white (surface) and an in-void part (the high density part in the original) can be provided with the surface density. In the in-void area, a selector 1321 selects averaging data of the averaging part 1307, the selector 1322 selects an in-void signal Nin1 and a buffer 1311 outputs averaging data.

Abstract: PURPOSE:To ensure that the same result can be obtained in printing data on a vertically long sheet in a running direction as that obtained in printing data on a laterally long sheet by expanding print data in dots in drawn image memory depending on a direction in which the sheet runs and reading the expanded data for printout. CONSTITUTION:When a vertically long sheet is used, an image drawing control device 11 expands print data in dots in drawn image memory 12. Then a data sending device 13 reads the data expanded in dots sequentially and allows a printing device 14 to print the data. Subsequently, in this case, the same result is obtained in printing data on the sheet as that obtained in printing data on the vertically long sheet using a conventional printer. On the other hand, when a laterally long sheet is used, the image drawing control device 11 expands print data in drawn image memory 12 from an address corresponding to a reference position suited to the laterally long sheet. Next, the data sending device 13 reads the data from a reading start address in accordance with the laterally long sheet sequentially and allows the printing device 14 to execute the printout process. Accordingly, it is possible to obtain the same result in printing data on the laterally long sheet as that obtained in printing data on the vertically long sheet.

And, when rotation starts to advance from the lower picture, the rate of the change in an area to a rotational angle between the figures S 1  and S 2  turns gradual increase in the rate of change in the area of the figure S 2 , and when the rate of change in the area between the figures S 1  and S 2  is extremely small, the tips 25 and 23 of the 2nd and 3rd small grooves 16 and 17 are opened in the figures S 1  and S 2 . Therefore, extraordinary high pressure and low pressure are not caused in the figures S 1  and S 2  and thus the noises caused thereby are not generated.
