Title: Image normal position controller
Inventor: NARUKI HIDETOSHI
IPC: H04S1/00
Filed: 1993-10-08
Abstract: PURPOSE:To reduce holding coefficients and to correspond to multiple image normal positions by holding only one coefficient by means of setting the coefficients in symmetrical image normal positions on right and left to be a pair of common coefficients. CONSTITUTION:The coefficients in the image normal positions of 0-180 degrees are held in coefficient ROM 3. A coefficient supply means 4 supplies the coefficients from ROM 3 to convolvers 1 and 2. When the instruction of the image normal position is given to the means 4, the image normal position is judged. When it is the image normal position between '0' to 180 degrees, the coefficient corresponding to the position is supplied to the convolvers 1 and 2 as it is, and a convolution operation is executed. When the image normal position is between 180 degrees to 360 degrees, a position (0-180 degrees) in the symmetrical relation with the instructed position by right and left is obtained, and the coefficient of the obtained position is read from ROM 3. A pair of right and left coefficients are exchanged and the coefficients which are read are supplied to the convolvers 1 and 2 and the convolution operation is processed.

Title: Deflection correcting circuit of electron beam lithography equipment
Inventor: OKINO TERUAKI
IPC: H01L21/30
Filed: 1987-11-04
Abstract: PURPOSE:To facilitate highly accurate beam lithography without degrading a throughput by a method wherein a stage position error signal obtained in accordance with the measured value of a laser beam length meter is stored in a main deflector side first and then a correction value (LBC value) variance is stored in an auxiliary deflector side and, after that, the LBC value is stored in the main deflector side every time the LBC value variance exceeds the allowable value. CONSTITUTION:An LBC value stored in a register 13 is supplied to an adder 14 and added to main deflection data. A subtractor 16 calculstes the difference (LBC value variance) between the LBC fixed value (output of the register 13) and the LBC value afterwards and supplies the difference to an adder 15. As a result, the adder in an auxiliary deflector side adds an LBC correction value to auxiliary deflection data. A comparator 17 always compares the LBC value variance outputted from the subtractor 16 with an allowable value. If the LBC value variance exceeds the allowable value, a signal is supplied to the register 13 and the LBC value at that moment is stored in the register 13. With this process, the LBC value applied to the adder 14 becomes larger than before that time and the LBC value (output of the subtractor 16) is quickly reduced. As a result, an allowance is created again in the allowance region in the auxiliary deflector side.

Title: V-bending method for composite type damping steel plate
Inventor: NAKAMURA MICHIO
IPC: B21D5/01
Filed: 1987-11-06
Abstract: PURPOSE:To prevent the 'sea gull' phenomenon that both sides of bending part are bent in two steps by executing V bending by using the lower die made of the nylon whose Barcol hardness is at specified value and whose angle of both shoulder parts of a V groove is larger by specified angle than the punch angle. CONSTITUTION:The V bending of a composite type damping steel plate 4 is executed by the V die composed of a punch 8 and the lower die 9 which is made of the nylon whose Barcol hardness is 65-80, and whose angle of at least both shoulder parts of a V groove is larger by 15-30 deg. than that of the punch 8. When the punch 8 is lowered by placing a composite type damping steel plate 4 on the upper part horizontal face 9a of the lower die 9, the composite type damping steel plate 4 is bent in V shape by the punch 8. At this time the angle of both shoulder parts continued to the upper part horizontal face 9a is larger by 15-30 deg. than that of the punch 8 and also due to the material of the lower die 9 being made of nylon the load onto both shoulder parts is small. A stress concentration is thus not generated on the composite type damping steel plate 4 of the part coming into contact with both shoulder parts, no 'sea gull' phenomenon is caused and the V bending can be executed well.
