Title: Correcting method for electron beam writing exposure amount
Inventor: KAGA HIROYASU
IPC: H01L21/30
Filed: 1987-12-02
Abstract: PURPOSE:To exclude the influence of electric field radiation noise, and enable keeping electric charge to be given to resist constant, by detecting the instantaneous value of an electric field radiation current accompanied by electric radiation noise, and adjusting the length of exposure time in accordance with the ratio of the mean value of the electric field radiation current as a basis to determine the exposure time to the detected instantaneous value. CONSTITUTION:Electron beam from an electric field radiation electron gun is thinly stopped down, exposure time is set in accordance with the mean value <i> of an electric field radiation current, and a specific amount of electric charge is given to resist, which is exposed. The correcting method of exposure amount in this electron beam writing process is as follows. The instantaneous value <i> of the electric field radiation current accompanied by electric field radiation noise is detected. The length of exposure time is adjusted in accordance with the ratio of the mean value <i> of electric radiation current as a basis to determine the above exposure time to the detected instantaneous value <i>. Thus the amount of charge to be given to resist is kept constant. For example, the radiation current during writing is detected with a beam monitor 6. An operating unit 57 calculates the mean current value <i> and the ratio of the mean current value <i> to the instantaneous current <i>. A correction operating unit 59 multiplies a value produced by an exposure time producing part 51 by the above ratio, and obtains a corrected exposure time.

Title: Production of optical fiber preform
Inventor: ITO HIDEAKI
IPC: C03B37/014
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To prevent the fluctuation in the pressure in an evacuating chamber and to prevent an atmospheric gas flowing to the outside by controlling the flow amt. of air which flows by suction by a sucking device into the evacuating chamber through the space between the supporting rod which supports a porous preform and the insertion hole of the rod to specified times or more as the flow amt. of supplied atmospheric gas. SOLUTION: An optical fiber preform is produced by heating a porous preform 1 while supplying an atmospheric gas such as chlorine gas or the like from a supply device 5 to a muffle tube 3 and operating a sucking device 8 to keep the inside of the tube in a negative pressure state, and then dehydrating and sintering. In this process, the flow amt. of air flowing into an evacuating chamber 6 through the space between an insertion hole 10 and the supporting rod 2 is controlled to >=10 times as the supplied flow amt. of the atmospheric gas. With the larger ratio compared with the average flow amt., the fluctuation ratio of the flow amt. caused by fluctuation in the operation of the sucking device 8 is decreased, and the higher degree of the effect can be obtd.  The ratio of the amts. of entering flow and supplied flow is adjusted by controlling both or either of the sucking flow amt. by the sucking device 8 or the inner diameter of the insertion hole 10.

Filed: 1986-12-24
Abstract: PURPOSE:To decrease the increase of the hardware quantity and at the same time to shift digits at a high speed by using a shifter which has a bit/digit shift switching function and performs the shifts of 1-4 bits also for shifts of 1-4 digits. CONSTITUTION:The data to be shifted is set at a B latch 4 from a B work 2 through a B bus 13. Then the data set at the B latch 4 is shifted by a shifter 7 by the number of shifts shown by a shift control circuit 11 via a bit/digit selector 6 which is switched to the bits or digits by the circuit 11 controlled by a microprogram. The shift output is set at a C latch 10 through a bit/digit selector 8 switched by the circuit 11 and then an output selector 9 and then delivered to a C bus 14 to be set again at the work 2. As a result, a shift up to 4 digits is carried out just with a single shift action. Then the normalizing or digit matching tasks are carried out at a high speed in case the digit data like the floating point data is treated.

Inventor: SASAKI TAMOTSU
IPC: H01L21/68
Filed: 1991-10-25
Abstract: PURPOSE:To quickly align the direction of orientation flats of a plurality of semiconductor wafers in the same direction. CONSTITUTION:At a plurality of wafers 18, axial lines of the individual wafers are directed in a direction which is parallel to a notch alignment roller 14. While the individual wafers 18 are being held so as to be capable of being turned and moved in up-and-down direction, the notch alignment roller 14 is turned in a state that outer circumferences of the individual wafers 18 have been brought into contact with a notch coupling part 14a at the notch alignment roller 14 from the upper part. Thereby, the individual wafers 18 are turned simultaneously when they come into rolling contact with the notch coupling part 14a. However, when notches 19 are turned up to the notch coupling part 14a, both are coupled and the wafers 18 cannot be tuned any more.
