Title: Charged particle beam lithography
Inventor: SUGATA MASANORI
IPC: H01L21/027
Filed: 1990-07-18
Abstract: PURPOSE:To reduce the total sum of the blanking time and, thereby, to shorten the drawing time by a method wherein a drawing operation for a next line is executed immediately before it in a direction opposite to the drawing operation and a blanking operation to start the drawing operation for the next line is executed according to the distance between a final pattern position of an immediately previous line and an initial pattern position in the next line. CONSTITUTION:A position designation signal (X0+3px) is sent to a subtracter 46 from a pattern position register 31. An X-direction pitch signal px is sent to the subtracter 46 from an X-direction pitch register 33. Consequently, after the subtracter 46 has subtracted the pitch signal px from the position designation signal (X0+3px), its subtracted value (X0+2px) is reset to a pattern position register 31. Patterns A, B are drawn in the same manner on the basis of a reference point (X0+2px, Y0+py), and a counter 34 counts one. In addition, the position designation signal (X0+2px) from the pattern position register 31 is sent to the subtracter 46 via a changeover circuit 45. A subtracted value in which the pitch signal px has been subtracted from the position designation signal (X0+2px) by using the subtracter 46 is reset at the pattern position register 31; the patterns A, B are drawn.

Title: Electromagnetic shielding sheet
Inventor: OGUCHI MASAHIRO
IPC: B22F1/00
Filed: 1988-07-29
Abstract: PURPOSE:To obtain an electromagnetic shielding sheet having excellent orientation by dispersing at least one of flakelike amorphous magnetic alloy having specific thickness and aspect ratio and powderlike amorphous magnetic alloy having specific short diameter and long diameter and aspect radio in specific volume % of rubber base. CONSTITUTION:The aspect ratio of amorphous magnetic alloy is 5 or more. If the aspect ratio is 5 or more, the orientation of the alloy is improved. If the aspect ratio of a flake is 5 or less, the orientation of the flake and the engagement of the flakes are deteriorated. The thickness of the flakes is ranged at 0.5-5mum. If the thickness is less than 0.5mum, many holes exist in the powder, and electromagnetic shielding effect of low frequency of 1kHz or less is eliminated, while if it exceeds 5mum, its flexibility is deteriorated. If the diameter of the powder particle is 25mum or less, a predetermined aspect ratio cannot be provided, while if it exceeds 1000mum, it becomes difficult to knead the flake powder uniformly with rubber. If the using amount of the flake and the powder is less than 5vol.% of the volume of the sheet, its electromagnetic shielding effect is deteriorated, while if it exceeds 30vol.%, its shielding effect is increased, but the flexibility of the sheet is deteriorated.

Title: Pll circuit
Inventor: TATEISHI HISAO
IPC: H03L7/14
Filed: 1988-07-28
Abstract: PURPOSE:To shorten stable time without bringing about a lockout by controlling the operations of the first and second PLL circuits by an external control signal and always setting the free running frequency of a voltage controlled oscillator to a desired frequency by the second PLL circuit. CONSTITUTION:When an external control signal RCTL is a low level, the second PLL circuit 2 makes a sample-and-hold circuit 25 into a sampling state, inputs the output of a charge pump 24 through a low-pass filter 26 to a voltage controlled oscillator 15, further, makes the output of a switching circuit 13, for example, into a reference frequency signal SR having a 50% duty factor, and inputs the above-mentioned output to a low-pass filter 14. Namely, the first PLL circuit 1 is made into an open loop state, and the second PLL circuit 2 is made into a closed loop state. In this manner, when the external control signal RCTL is the low level, the free running frequency of the voltage controlled oscillator 15 can be always set to the desired frequency by the second PLL circuit 2. Thus, the lockout is never brought about, and the stable time can be shortened.
