Title: Protective circuit in thyristor rectifier from surge voltage
Inventor: HASHIZUME TOSHIAKI
IPC: H02M1/00
Filed: 1980-06-02
Abstract: PURPOSE:To prevent the breakdown of thyristors by checking the discharge of the charges in capacitors to a main circuit side by connecting diodes to capacitors in series wherein discharging resistors are also connected to the capacitors in parallel. CONSTITUTION:A pair of capacitors 10a, 10b are connected in series with the AC side buses in a thyristor rectifier 16 respectively and doides 12a, 12b are also connected in series with the opposite terminals of the capacitors 10a, 10b in reverse polarity. And the connection points of the diodes 12a, 12b are connected to common fuses 14 for short-circuit protection. Furthermore, the connection points of a pair of the series-connected capacitors 10a, 10b are grounded respectively. In this way, the charges charged in the capacitors will be prevented from discharge to a main circuit side by the diodes and are discharged through discharging resistors 18a, 18b. Therefore, the breakdown of thyristors at the time of turning on the thyristors in the thyristor rectifier can be prevented.

Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To provide chrominance converters reducing an interpolation error by simple method without increasing the size of a conversion table as far as possible. SOLUTION: These converters convert an inputted chrominance signal expressed by a coordinate value in an n-dimensional chrominance space which can define a color difference by a distance to a desired output chrominance signal. The chrominance converters 11 to 14 are respectively provided with a conversion table indexed by the high-ordered digit of an each-dimensional input coordinate value in n-dimensional chrominance space and a linear interpolation means. First values consisting of plural coordinate values surrounding the output coordinate value of each-dimension corresponding to the inputted coordinate value are respectively obtained from the each- dimensional conversion table.  A line interpolation means obtains a second value by linear interpolation using the low-ordered digit of the each-dimensional input coordinate value in the n-dimensional chrominance space from the first value of each-dimension. The second value is supplied to one-input and one-output conversion means 21 to 24. The one-input and one-output conversion means 21 to 24 convert a value directly proportional to the color difference in an n-dimensional distance space to a corresponding output chrominance signal to obtain the output chrominance signal.

Title: Tape tension controller for magnetic recording and reproducing device
Inventor: SUZUKI MICHIHITO
IPC: G11B15/43
Filed: 1990-03-23
Abstract: PURPOSE:To prevent the sag, etc., of a tape and to decrease the defect of recording and reproduced image quality by strongly driving a reel motor if a tension value is below the prescribed threshold lower than an adequate value, thereby rapidly controlling the tension value is below the prescribed threshold lower than an adequate value, thereby rapidly controlling the tension value to the adequate value. CONSTITUTION:A tension detecting lever 15 and a photointerruptor 20 detect the tension value by the displacement of a tension arm and the output of the photodetecting light quantity of the photointerruptor 20 is applied via an amplifier 21 to a comparator 22 and a 1st motor driving section 23. The comparator 22 discriminates the tension value by the threshold value Vref to a prescribed level. The discrimination output is applied to the 1st motor driving section 23 and a 2nd motor driving section 24. The 1st motor driving section 23 drives the reel motor 25 until the adequate value is attained when the tension value exceeding the threshold is detected. The 2nd motor driving section 24 drives the reel motor 25 and sharply increases the tension value when the tension value is between the threshold value. The generation of the defect of the recorded image quality by the sag of the tape is lessened in this way.

Title: Reduction-type x-ray lithography
Inventor: MORIGAMI MITSUAKI
IPC: H01L21/027
Filed: 1990-03-23
Abstract: PURPOSE:To lessen the effect of diffraction and to realize high resolution by moving a mask and a resist surface in synchronism a specified distance and by transferring a pattern on the mask by X-rays of a specified thin beam size while scanning the pattern. CONSTITUTION:At first, X-rays 2 are dispersed by a monochrometer 3 and X-rays of a desired wavelength passes through. The divergence of the X-ray beam is suppressed vertically and horizontally by using two pairs of monochrometers 3 of a longitudinal direction monochrometer 3a and transversal direction monochrometer 3b. Then, X-rays 2 whose beam size is restricted to a specified size by a metallic shaping aperture 8 pass through a part of a mask 6 whereon a pattern 6a is mounted, reduce is size vertically and horizontally by first and second reduction reflection crystals 4, 5 and forms a reduced pattern on a resist 7a. The mask 6 and a substrate 7 which is coated with the resist 7a move synchronously in accordance with the reduction rate. The X-ray beam 2 is deflected to scan the pattern 6a and a reduced pattern is transferred on the mask 6 on the resist 7a. Since the X-ray beam 2 is reduced thin by the shaping aperture 8, it is possible to reduce the distance from the reduction reflection crystals 4, 5 to the resist 7a.
