Title: Laser lithography system
Inventor: OKUYAMA TAKASHI
IPC: B23K26/00
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To execute suitable and highly accurate scaling correction processing for the dimensional fluctuation of a body to be pattern formed. SOLUTION: Positioning marks P1, P2, P3 and P4 are provided at four corners of a nearly rectangular base plate 20, and relative coordinates are obtained. The degree of expansion and contraction, and the inclination, in a main scanning direction, of a straight line obtained by connecting marks P1 and P2 and that obtained by connecting the marks P3 and P4 in a main scanning (Y) direction are calculated based on the coordinates of the marks P1, P2, P3 and P4. The degree of expansion and contraction and the inclination of an intermediate scanning line are obtained on an assumption that the degree of expansion and contraction, and the inclination in a subscanning (X) direction are linearly changed, so that the base plate 20 is positioned by an X-table 14 and an θ-table 16. Also, an error due to the rotation of the base plate 20 at the time of correcting the inclination is obtained, so that the position of the base plate 20 is corrected.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of bright and dark parts in a field when an image is picked up by a method wherein a lens material layer is formed on a lens fixing layer by conducting selective etching on the unnecessary part of the lens fixing layer, and a microlens is formed by processing the lens material layer. SOLUTION: A color filter layer 6 is formed on the surface of a substrate 1 through a color filter fixing layer 5 consisting of organic material. A lens- fixing layer 7 is formed thereon, and a groove 9 is formed on the surface of the lens-fixing layer 7. Besides, a lens material layer 8a is formed on the lens- fixing layer 7, and a microlens 8 is formed by processing the lens material layer 8a. Then, a positive type photoresist film 10, to be used for selective etching of the lens-fixing layer 7, is formed, and the lens-fixing layer 7 is etched using the photoresist film 10 as a mask. As a result, the generation of difference in brightness and darkness in the field when an image is picked up can be prevented.

Title: Gain adjusting method
Inventor: KOYAMA KENICHI
IPC: G05B13/00
Filed: 1988-12-19
Abstract: PURPOSE:To easily adjust a feedback servo system which handles a digital signal by performing control so that the gain intersection of the feedback servo system coincides with a disturbance frequency when the output of a counter reaches a specific value. CONSTITUTION:A triangular or rectangular wave whose most significant digit bit has about 55% duty is used as a disturbing signal waveform. A phase comparison is made by exclusively ORing the most significant digit bits of respective signals, the duty of the output is measured by a counter 10 which counts a clock of frequency Fp, which is set to 2N.Fg (where N is an integer >=1 and Fg is the frequency of the disturbing signal). Consequently, when N=3, there are eight clocks 6A, the frequency of the output 8A of an exclusive OR gate 8 is twice as high as that of disturbance X, and the output 9A of an AND gate 9 is generated four times in one cycle of the disturbance X; and the output 10A of the counter 10 is latched 12 after counted up to 4 and an output 12A is invariably 4. At this time, a control circuit 11 fixes the value of its output 11B, i.e. the multiplicator of a multiplier 2.

Title: Protective circuit against alternating current mixed contact
Inventor: OKA RITSUO
IPC: H02H3/20
Filed: 1989-12-13
Abstract: PURPOSE:To perform protection securely at the time of AC mixed contact by changing the polarity of the gate voltage of a reverse conducting gate turn off thyristor, by a switching signal from a mixed contact signal detector. CONSTITUTION:If a mixed contact has occurred between a distribution line and a line, line L1 for example, and the voltage of the junction of diodes D1 and D2 exceeds the endurable voltage of the diodes, a current flows into a mixed contact signal detector SD through the diodes D1, D2. This makes the detector SD send out a switching signal having a required constant level, and connects a point (a) with a point (b) by moving the contact segment (g) of a gate signal switching circuit GS. This makes the gate voltage of gate turn off thyristors S1, S2 negative polarity and turns them off into a cut-off state by a battery Bb. Accordingly, the line is interrupted and a circuit A to be protected can be protected.

Title: Method for adjusting damping characteristic in surface acoustic wave device
Inventor: FUJII YOSHIMORI
IPC: H03H9/64
Filed: 1988-12-19
Abstract: PURPOSE:To adjust a damping quantity at each frequency individually by forming a film for mass additional processing on either inter-digital transducers IDT, and moving only the damping characteristic of the IDT to a low frequency side. CONSTITUTION:Since the film 4 for mass additional processing is formed on either two IDTs 2 and 3, only the damping characteristic of the IDT on a side where the film is formed is moved to the low frequency side. And since entire damping characteristic is formed by synthesizing the damping characteristic of the IDT on one side with the one of the IDT on the other side, the damping quantity can be set at a level a little higher by estimating what value of damping quantity can be obtained based on the amount of travel to the low frequency side by the mass additional processing when the damping characteristics of two IDTs 2 and 3 in advance, or a processing to move synthesized damping characteristic to a high frequency side is applied after a mass additional processing is performed. ln such a manner, it is possible to set a frequency fs for voice carrier, a frequency fc for chrominance subcarrier, and a frequency fp for video carrier at desired ranges, separately.

Title: Dc transmission facility
Inventor: KUWABARA TAKASHI
IPC: H02H7/125
Filed: 1993-12-21
Abstract: PURPOSE:To decrease the number of series circuits of thyristor regardless of the limit voltage of an arrester by detecting overvoltage generated in an AC/DC converter and firing a thyristor connected in reverse parallel with the thyristor in the AC/DC converter. CONSTITUTION:When an overvoltage exhibiting the plus electrode at the AC terminal 8 of a converter is generated on the DC line 4 side, it is detected by a voltage detector 11. A detection signal is delivered from the detector 11 through a cable 12 to a thyristor 9 which is thereby fired thus dropping the potential between the DC line 4 and the terminal 8 substantially to zero. Consequently, the overvoltage disappears in the form of current flowing into the thyristor 9. When an overvoltage exhibiting the plus electrode with respect to the DC line 4 is generated on the terminal 8 side, it is detected by a voltage detector 14. A detection signal is fed through a cable 15 to a thyristor 13 which is thereby fired and the potential between the DC line 4 and the terminal drops substantially to zero thus dissipating the overvoltage.
