IPC: H04N9/28
Filed: 1986-02-20
Abstract: PURPOSE:To make unnecessar a complicated interpolation arithmetic circuit, and to adjust a convergence dislocation rapidly and with accuracy, by performing the approximate calculation of a correction data corresponding to a scanning line between adjusting points in a vertical direction, and providing a 1 frame memory which storage the correction data at the adjusting point, and between the adjusting points in the vertical direction. CONSTITUTION:Since only the correction data of a position corresponding to the adjusting point is written in a 1 frame memory (RAM) 4, it is necessary to write the correction data at every M-number of scanning lines included between the adjusting points in the vertical direction by finding it with the approximate calculation. Then, for example, a change share by every scanning line between the adjusting points is found from a correction quantity (a) on the first line, and a correction quantity (b) on the second line, and the correction quantity by every scanning line is found by adding the change share with the correction quantity on the second line. Next, the output signals of the 1 frame memory (RAM)4 are converted to analog quantities with D/A converters 5-8 for each color, and are smoothed at low-pass filters (L.P.F) 9-12, and after being amplified at amplifiers 13-16, they are supplied to convergence yokes for each color.

Abstract: PURPOSE:To obtain coumarins useful as a perfume in high purity by previously distilling a reactional mixture and then carrying out reaction in subjecting 3-(2-oxocyclohexyl)propionic acid ester to cyclodehydrogenating reaction. CONSTITUTION:A compound expressed by formula I (R<1> to R<4> are H, methyl or ethyl; R<5> is 1-4C alkyl) is subjected to the chclodehydrogenating reaction in the presence of a fixed metallic catalyst (e.g. Pd supported on active carbon) at 100-350 deg.C to afford coumarins expressed by formula II. In the process, the reactional mixture is previously distilled to remove high-boiling substances so as to reduce the total amount of contained 3-cyclohexylpropionic acid O- ethylphenyls and 3-phenylpropionic acid O-ethylphenyls to <=3wt.% based on the coumarins and the content of 3-(2-hydroxyphenyl)propionic acids to <=1wt.% based on the coumarins. The resultant reactional mixture is then rectified to afford the coumarins with contents of <=0.1wt.% O-ethylphenols and <=0.2wt.% 3,4-dihydrocoumarins. The obtained coumarins are further crystallized to provide the objective substances of high purity.

Abstract: PURPOSE:To enable high-speed transmission by interposing a resistor which has a resistance value close to the value, obtained by subtracting a half of the impedance of a bus from the impedance of a branch wire, between the branch wire and bus. CONSTITUTION:Respective circuit blocks 1-4 have resistors 80-83 and transmission lines 11-14 or 41-44; and the lines 11-14 and lines 41-44 are designed matching the same characteristic impedance or a value close to it.

In this signal transmission circuit, the resistance value of the resistors 80-83 is set to the value obtained by subtracting the half of the impedance of the bus 100 from the impedance of the line 11. Consequently, the resultant impedance of the resistor 80 and bus 100 which is viewed from the line 11 becomes equal to the impedance of the line 11 and the repetition of reflection in the branch line can be prevented. Further, the resistors 81-83 are set by similar methods.

Title: Production of high-strength optical fiber
Inventor: SAKAGUCHI SHIGEKI
IPC: C03C25/62
Filed: 1982-03-11
Abstract: PURPOSE:Optical fibers, immediately after spun, are subjected to plasma etching to remove cracks on their surfaces and coated with a resin composition, before contacting with other solid matters to produce high-strength optical fibers. CONSTITUTION:The parent material for optical fibers is surface treated, e,g., by hydrofluoric etching of flame abrasion and made into fibers by means of a resistance furnace or laser furance. The resultant optical fibers are introduced into a plasma etching unit to effect etching on their surface and remove cracks on thier surfaces. Then, before these optical fibers come into contact with other solid substances, they are subjected to primary coating with a silicone resin or the like continuously, further to secondary coating by extrusion of a nylon resin or the like. The effective combination of the flexible primary coating and the secondary extrusion coatings results in additional increase in the strength of the optical fibers. The thickness of the coatings are in general 100-200mum.
