Title: Exposure device
Inventor: SUZUKI AKIYOSHI
IPC: H01L21/30
Filed: 1985-02-12
Abstract: PURPOSE:To contrive the enhancement of a virtual size of a picture by scan- illuminating the surface of a reticle partly with an aperture and moving the reticle or a wafer in a direction of an optical axis of a projection optical system while syn chronizing it to the scanning. CONSTITUTION:During the first exposure, a drive device 14 drives a stage 11 in Z-axis directions i.e., in a direction of an optical axis S of a projection optical system 9 corresponding to the scanning position on a reticle 8 surface of an aperture image 4'. A drive controller 15 controls the drive quantity in Z-axis by synchronizing it to oscillation mirrors 5 and 6 so as to bring the above quantity in accordance with the characteristics of curvature of image field of the projection optical system 9 which has been worked out previously. For example, assuming that the curvature of image field of the projection optical system 9 is formed and the aperture image 4' is projected on the position distant (a) from the optical axis S on a wafer surface 10, wherein the exposure is done after the stage 11 is driven to the side of projection optical system 9 by a distance (b) compared with at the exposure of the center of optical axis, the pattern image of high resolution can be obtained also in the region distant (a) from the optical axis S almost similarly in the position fo the optical axis S.

Abstract: PURPOSE:To obtain the subject compound in high purity and yield by oxidizing an easily available 2-alkyl-6-acylnaphthalene, separating the obtained compound from the system, precipitating and removing impurities from the resultant mother liquor by concentration, cooling, etc., and reusing the purified liquor in the reaction. CONSTITUTION:A 2-alkyl-6-acylnaphthalene produced by the acylation of an easily available 2-methylnaphthalene is oxidized with an O2-containing gas in acetic acid solvent in the presence of a catalyst containing Co and Mn to obtain 2,6-naphthalenedicarboxylic acid. In the above process, the mother liquor left after the separation of 2,6-naphthalenedicarboxylic acid crystals from the reaction product is partly or totally cooled or concentrated and cooled, the precipitated impurities are removed and the purified liquor is reused in the oxidation reaction. The process is industrially advantageous, because 2,6- naphthalenedicarboxylic acid useful as a raw material for high performance polyester can be produced in high purity and yield.

Title: Device for reproducing video signal
Inventor: TANAKA SOICHI
IPC: G11B19/02
Filed: 1990-02-06
Abstract: PURPOSE:To improve the operability of the video signal reproducing device by setting up a mode for speed-variably moving a recording medium while reproducing a video signal by rotating a rotating operation part and a mode for rapidly moving the recording medium without reproducing the video signal. CONSTITUTION:The rotating operation part 12 is constituted so that a rotary ring 12a is rotated from the position of a mark MS up to the positions of marks ML, MR and a reproducing key 13 is arranged on a center part. In the 1st mode for outputting a video image, i.e. the ring 12a is rotated during the period of reproducing or stopping, variable speed reproducing is attained. In the 2nd mode in which a reproduced image is not outputted, i.e. at the time of stopping the rink 12a, quick feeding or rewinding operation is attained by the rotating operation part 12. Thus, the number of operation keys is reduced. In addition, the operability of the device is improved by sensuously understanding an operation method.

Title: Industrial robot controller
Inventor: SUGIMOTO KOICHI
IPC: B25J13/00
Filed: 1990-02-06
Abstract: PURPOSE:To control an industrial robot with high accuracy by providing a means which detects the displacement of an actuator and a means which decides the value of coefficient of an arithmetic formula and outputting the speed of the actuator as the command value to be given to the servo system of the actuator. CONSTITUTION:A force sensor 2 detects a force vector, the inverse of (f) and a moment vector, the inverse of (m) of a three-dimensional space which acts on a decided reference point P of a hand 3. Both the force vector and the moment vector are shown by a coordinate system xyz fixed to the sensor 2. A servo amplifier device consists of six servo amplifier grounds and controls six actuators respectively. A single servo amplifier 5a receives a command signal from a controller 4 and performs the control so that an actuator 6a has a motion at a speed accordant with the level of the command signal. A detector 7a is attached to the actuator 6a for detection of the speed and the displacement. Then a speed signal S1 and a displacement signal S1 are fed back to the amplifier 5a and the controller 4 respectively. As a result, the arithmetic value is reduced.

Title: Solid-state color image pickup device
Inventor: MATSUDA TETSUAKI
IPC: H04N5/347
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To provide the color images of high movement resolution and high sensitivity by resetting the final electric charge detection part of the horizontal transfer part of a CCD by a prescribed odd-numbered picture element number and amplifying and correcting a lacking chrominance signal level in an amplifier after a color separation circuit. SOLUTION: In the final electric charge detection part of the horizontal transfer part of the CCD 11, by performing reset for every signals for three picture elements, luminance signals provided with a tripled signal level compared to the case of performing the reset for each picture element are obtained. Then, by performing almost triple time amplification by the amplifier 18 provided after the color separation circuit 14, the lacking chrominance signal level is corrected and almost normal highly sensitive color images are obtained without lowering the movement resolution.  Since the reset is performed for every three picture elements, the picture element number of output signals is reduced to 1/3, however, since the bright color images whose luminance level is almost tripled are obtained, it is suitable for picking up the image of a dark object at night or without sufficient illumination.

Title: Error detecting system
Inventor: OONISHI MASARU
IPC: H03M5/04
Filed: 1983-02-18
Abstract: PURPOSE:To attain the error detection of the mBIC code rule without synchronism by ORing exclusively an input signal and a signal delaying the said input signal by a 1-bit delay circuit. CONSTITUTION:A (0) level holding circuit 8 is a circuit keeping to output (0) until a reset signal is inputted when an output of an AND circuit 7 is (0). The output of the circuit 8 is logical (1) when an input to supervisory circuits 4-1-4 is always logical (1), and the output goes to (0) until a reset signal is inputted when (0) is inputted once. Since an output of the EX-OR between a c-bit and a bit just before the c-bit is always logical (1) normally, a bit output of a shift register 3 corresponding to the c-bit goes to (1). The probability of (1) and (0) for the EX-OR of other bits is 1/2 and the probability where the output of the supervisory circuit is logical (1) closes to (0) when the period is increased. Thus, the error is detected by supervising the output of the supervisory circuit.
