Title: Extraction of polyol from aqueous polyol solution
Inventor: YAMAMOTO TAMECHIKA
IPC: C07C27/00
Filed: 1979-09-12
Abstract: PURPOSE: A solvent that has small compatibility with water and large difference in specific gravity from the polyol aqueous solution such as benzene is used to extract polyol from the polyol aqueous solution at high temperatures, thus economizing heat consumption and producing high-purity polyol with low water content.  
     CONSTITUTION: In the extraction of polyol from the aqueous solution, a nonpolar or low polar solvent such as benzene, toluene, xylene or their mixture is used to extract at a high temperature of 150W250°C, preferably near 200°C. Industrially, this operation is conducted continuously by means of a multistage counter-current extractor.

Title: Demagnetization
Inventor: NISHIGAKI YUKIO
IPC: H01F13/00
Filed: 1979-09-13
Abstract: PURPOSE:To enable the consecutive demagnetization of a material with a simple constitution by a method wherein the material to be demagnetized is made to pass in a constant speed through a coil converting the polarity of flowing current having a prescribed D.C. value. CONSTITUTION:A constant current Im irrelevant to time is kept to flow in a coil 10, and a material 11 to be demagnetized is made to pass in a constant speed  through the coil 10. By this way, the strongest polarity converting demagnetizing field is applied to the material 11 at the center of the coil 10, the intensity of magnetic field decreases in proportion to the increase of distance from the center and finally becomes to zero. Consequently as the demagnetizing field in the material 11 changes from the maximum to the minimum that the same effect with the decay of magnetism by a direct current demagnetization is given to the material 11. By this way, the material 11 can be demagnetized consecutively with a simple constitution.

Title: Halogen labelled compound including estradiol derivative, synthetic intermediate and synthesis thereof
Inventor: RICHIYAADO JIEE BARANCHIYUKU
IPC: C07J1/00
Filed: 1986-05-21
Abstract: A method of preparation of halogen labeled organic compounds is described. In particular, estradiol derivatives labeled by halogen substitution at C-16 are synthesized according to the present invention. A triflate intermediate is prepared from which either 16-alpha-halo-substituted-17- beta-estradiols or 16-beta-halo-substituted-17-beta-estradiols can be rapidly formed as desired. ln particular, the preparation of 16-alpha-<sup>123</sup>I-17-beta-estradiol and 16-beta- <sup>123</sup>I-17-beta-estradiol are shown and are synthesized from a 17-beta-estradiol-16-beta-triflate. Both 16-alpha-<sup>123</sup>I-and 16- beta-<sup>123</sup>I-17-beta-estradiol made according to the present invention are shown to have a high specific activity. The method of synthesis is sufficiently rapid so that the relatively short half-life of <sup>123</sup>I is readily accommodated. The high stereospecificity of each step of the reaction sequence in preparing the labeled estradiols provides for highly efficient syntheses and little waste of radio-label.

Abstract: PURPOSE:To utilize to the maximum an operating speed of a microprocessor and a memory, and to raise a performance of a device by extending a clock supplied to the microprocessor, only when a memory error is confirmed. CONSTITUTION:A bus cycle BC2 shows a timing in case when a memory error is generated. When a memory error signal MEMERR is generated, an FF143 latches (in the case, a clear input of the FF is P4 and inactive) this signal by a timing of a time t15, and closes an AND gate 144 and 145. As a result, an input of an FF142 is controlled so that a bus cycle T4 does not fall at the next time t16, and the bus cycle T4 falls at the next time t17, by which the bus cycle is ended by one clock, and a data in which a memory error data has also been corrected is supplied to a microprocessor.

Title: Deflection yoke for in-line type color cathode-ray tube
Inventor: KOBAYASHI KENICHI
IPC: H01J29/76
Filed: 1986-05-23
Abstract: PURPOSE:To obtain a large CRT having excellent convergence characteristis, by connecting a pair of diodes, which are connected in parallel and with inverse polarities, in series with a vertical deflecting coil winding for controlling a saturable reactor, and then connecting a resistance in parallel with said connection. CONSTITUTION:A pair of diodes D1 and D2, which are connected in parallel and with inverse polarities, are connected in series with a vertical coil winding (inductance Ls and resistance R5), and then resistance R is connected in parallel with said connection. Regarding a silicon diode, current I rapidly rises from the point where voltage V is near 0.7 V. Therefore, current almost flows across the resistance During a vertical deflection current Iv is small. However, from the point where the voltage across paired diodes D1 and D2 becomes in excess of a rising voltage Vrise, the current starts to flow across the diodes and the vertical coil winding of a saturable reactor, so that the saturable reactor starts its operation. The relation R>Rs is suitable for enlarging a correction efficiency, and cross mis-convergence can be adjusted by making the resistance R variable.

Filed: 1989-05-12
Abstract: PURPOSE: To limit error propagation so as to maintain other specified characteristics than d, k codes by reversing a binary digit 0 directly before and after a single binary digit 1 into a binary digit 1. CONSTITUTION: Two bits of non-constraint data are received through a line 10 at a time, and m/n encoder 11 encodes two non-restraint data bits into five channel bits. Apart of the encoder 11 is a modified d and k encoder, and a channel 12, which encodes d and k into 3, 7 or 4, 20 of a channel sign format, outputs a signal to the modified d and k decoder during reading from the medium or from a communication channel. This decode includes a n-to-m decoding transformation function (by decoder 13). The decoder 13 outputs the non-restraint data of two bits to the line 14 at a time. Thus, error propagation is reduced less than in normal d, k coding even at an increased information density.
